Curvature Perception of Mesenchymal Cells on Mesoscale Topographies
Authors: Frey Kerstin , Brunner Michael , Curio Christóbal , Kemkemer Ralf
Published: December 2024

Cells can sense geometrical cues with sizes of several tens of micrometers in their vicinity. Recent in vitro studies show that cells can adapt their shape, align along specific directions, or regulate other cellular functions when grown on surfaces with curvatures larger than their size. Although possible mechanisms for such responses like the alignment along axial cues have been suggested, a detailed understanding of the involved cellular processes remains open. This work addresses this gap by systematically investigating mesenchymal cell and nucleus orientation responses using a low‐cost model surface platform, the CurvChip. Using an array of cylindrically curved topographies with radii of curvatures ranging from tens to hundreds of micrometers, the contact guidance response of cells and nuclei is quantified in dependence on substratum curvature and manipulation of cytoskeletal components. Results suggest a desired perceived curvature for the investigated cells, and a very sensitive and robust curvature perception mechanism, as the effect of pharmacological manipulation of cytoskeletal components is relatively small. Furthermore, a comparison with previously published work strengthens the hypothesis of an involvement of the nucleus in the cell response to three‐dimensional (3D) curvatures.

Published: December 2024

Organic light‐emitting diodes (OLEDs) based on hyperfluorescent system have attracted widespread attention due to their ability to simultaneously achieve improvements in efficiency, lifetime, and color purity by combining the advantages of high exciton utilization sensitizers and high‐color purity emitters. Traditional hyperfluorescent systems typically involve three or four components and are severely sensitive to the doping concentration (≈0.5 wt%) of a terminal emitter, which inevitably causes high costs and difficulties in reproducibility. Here, a novel design concept for a matrix‐free hyperfluorescent (MFHF) system that employs a combination of an anti‐quenching TADF host and a high color purity MR‐TADF emitter is proposed. This strategy allows traditional concentration‐sensitive MR‐TADF emitters to significantly improve exciton utilization and reduce exciton lifetime at high doping levels, without the need for complex molecular modifications. The OLEDs with binary emissive layer achieve pure‐green emission, a maximum external quantum efficiency of over 30%, and a high maximum power efficiency of 145 lm W−1. The approach offers a straightforward and universal method to achieve anti‐quenching matrix‐free hyperfluorescent OLEDs with high color purity, making them promising for commercial applications in low‐cost ultra‐high‐definition (UHD) displays.

Published: December 2024

Aqueous zinc–sulfur batteries are a high‐capacity and cost‐effective energy storage technology. However, the performance is plagued by the dissolution of intermediate polysulfides formed during conversion. Here, this issue is addressed by developing aqueous rechargeable Zn‐sulfurized polyacrylonitrile (SPAN) batteries using tandem catalytic systems, containing water and tetraglyme (G4) with iodine (I2) additives. Mechanistic study and experiments reveal that the fully conjugated molecular configurations circumvent the formation of soluble polysulfides and enable reversible co‐storage of H+/Zn2+ with multiple redox‐active centers. The reduced I2 by G4 activates I−/I3− redox couple in SPAN, reducing activation energy, and accelerating Zn‐ion transfer kinetics. Additionally, it stabilizes the Zn anode by forming an organic–inorganic interphase that induces the generation of the predominant (002) plane. The as‐assembled Zn‐SPAN batteries exhibit excellent performances, with a high capacity of 1260.4 mAh g−1 at 0.2 A g−1, a high‐rate performance (409.3 mAh g−1 at 5 A g−1), and a long cycling stability (81.8% capacity remained over 800 cycles at 2 A g−1). This work takes a crucial step forward in organosulfur compounds accompanied by multi‐electron transfer for the high‐performance aqueous zinc‐ion batteries.

Published: December 2024

The photocatalytic reduction of carbon dioxide (CO2) to methane (CH4) represents a sustainable route for directly converting greenhouse gases into chemicals but poses a significant challenge in achieving high selectivity due to thermodynamic and kinetic limitations during the reaction process. This work establishes Ru‐OV active sites on the surface of TiO2 by anchoring coordination unsaturated Ru single‐atoms, which stabilize crucial reaction intermediates and facilitate local mass transfer to achieve dual optimization of the thermodynamics and kinetics of the overall photocatalytic CO2 reduction. Combining operando spectroscopy with density functional theory (DFT) calculations indicates that oxygen vacancies (OV) inhibits the desorption of *CO, whereas Ru facilitates proton extraction. This configuration not only lowers the overall activation energy barrier but has also been engineered to serve as a selectivity switch, changing the reaction route to produce CH4 instead of CO. Consequently, the Ru‐OV/TiO2 exhibits a 195.4‐fold improvement in the CH4 yield compared to TiO2, accompanied by an increase in selectivity to 81%.

Published: December 2024

Interfacial stability issues at the cathode remain a bottleneck to developing durable and high‐power all‐solid‐state lithium batteries (ASSLBs). In fact, the presence of conductive carbon in the cathode, necessary for high capacity and power capability, is believed to aggravate the stability woes. Thus, it is typically excluded from the cathode mix. Herein, employing a model functionalized carbon, it is shown that a small carbon surface oxygen functionality can in situ engineer a robust carbon–solid electrolyte interphase, which arrests conductive carbon‐mediated degradation of Li6PS5Cl into reactive polysulfides that degrades the active LiNi1/3Mn1/3Co1/3O2 (NMC) cathode. Such interfacial stabilization, as confirmed by ex situ spectroscopic and in situ impedance analysis, combined with fast charge transport facilitated by functionalized yet conductive carbon and lowly resistive cathode interphases, elevates the performance. This is evidenced by stable cycling at room temperature (22 °C) and elevated temperatures (60 °C), high rate capability, a Coulombic efficiency of 99.8%, and ≈100% capacity retention after 1000 cycles and >90% retention over 2000 cycles at 60 °C. Functionalized carbon‐mediated in situ cathode interfacial engineering offers a simple and scalable approach to designing durable ASSLB cathodes, with the potential for broader application across various NMC cathodes and compatible solid electrolytes.

Published: December 2024

Electrochemical carbon dioxide reduction reaction (CO2RR) to valuable fuels and chemical feedstock is a sustainable strategy to lower the anthropogenic CO2 concentration, thereby dynamising the carbon cycle in the environment. CH3OH on the other hand is undoubtedly the most desirable C1 product of CO2RR. However, selective electroreduction of CO2‐to‐CH3OH is very challenging and only limited catalysts are reported in literature. Pyrolyzing metal‐organic frameworks (MOFs) to generate carbon matrix impregnated with metal nanoparticles, heralds exciting electrocatalytic properties. This study unveiled the morphological evolution of a mixed‐ligand Ni‐MOF (Ni‐OBBA‐Bpy) during pyrolysis, to generate Ni nanoparticles anchored 0D porous hollow carbon superstructures (Pyr‐CP‐800 and Pyr‐CP‐600). This unique morphology invokes high specific surface area and surface roughness to the materials, which synergistically facilitates the selective electroreduction of CO2‐to‐CH3OH. In comparison to most of the previously reported Ni electrocatalysts that mainly produced CO, Pyr‐CP‐800 selectively yielded CH3OH with Faradaic efficiency (FE) of 32.46% at −0.60 V versus RHE (reversible hydrogen electrode) in 1.0 M KOH solution, which is highest among other reported Ni‐based electrocatalysts in the literature, to best of our knowledge. Additionally, insights from density functional theory (DFT) calculations revealed that Ni (111) plane to be the active site toward the electrochemical. CO2‐to‐CH3OH formation.

Developing non‐noble metal catalysts with excellent NH3 synthesis activity under mild conditions is a long‐term goal. The best catalysts reported to date often require laborious fabrication methods and controlled environments to fabricate the catalysts or high temperatures and long times to activate the catalysts. This work introduces a facile one‐pot method to fabricate carbon (C)‐based, barium (Ba)‐promoted cobalt (Co) catalysts via the citric acid sol–gel method with metal nitrates as precursors and water as the solvent. This approach ensures the homogeneous incorporation of metal ions into the carbon framework. The resulting (Ba/Co)0.3/C catalyst demonstrates an outstanding NH3 synthesis activity of 34 mmol gcat−1 h−1 (350 °C, 1.0 MPa) with excellent stability. In‐depth characterizations reveal that Ba exists as barium oxide (BaO), uniformly distributed on the carbon framework and around the Co nanoparticles. It is uncovered that retarding barium carbonate (BaCO3) formation in the fresh catalyst significantly reduces the reduction temperature and time (485 °C/4 h), which is a fundamental advantage of this method. Density functional theory and molecular dynamics simulations indeed support the experimental observations. It is anticipated that this simple and economical strategy will resolve the issues in a broad field of heterogeneous catalyst research.

The demand for wearable monitoring devices in contemporary medicine has significantly increased, especially in dynamic environments where traditional bulky equipment is impractical. Conventional flexible wearable devices or systems suffer from limited air and moisture permeability, lack of stretchability, and high power consumption, which restrict their long‐term usage and comfort. Herein, a stretchable and breathable backscattered monitoring system (SBBMS) is introduced, integrated with a fabric substrate. To address the challenges associated with fabric substrate system fabrication and encapsulation, a printing‐cutting‐transfer technology is proposed. This method enables the creation of unique, low‐cost, high‐precision, and robust circuit routing and electronic devices on fabric, maintaining high compatibility with commercial surface mounting technology while minimizing sacrifices in breathability. Additionally, a backscatter communication mechanism is designed and implemented to achieve wireless data transmission, which significantly reduces power consumption. Combined with energy management technology and hydrogel batteries, the SBBMS receives safe, multi‐source, and eco‐friendly energy support. Furthermore, through meticulous design, all modules—including the antenna, circuit, and battery—are made stretchable, providing the system with excellent strain‐resistive performance. The approach paves the way for the development of breathable, high‐performance, and highly integrated fabric‐based wearable systems, catering to specific user groups such as athletes, soldiers, and pilots.

Unter den nukleophilen Oxidationsmitteln, die bei der goldkatalysierten Oxidation von Alkinen eingesetzt werden, haben schwefelbasierte Reagenzien von Beginn an eine wesentliche Rolle gespielt und ermöglichten den Zugang zu den jeweiligen Goldcarben Intermediaten. Wir beschreiben hier das erste Beispiel für die Verwendung der Substanzklasse der Sulfoximine als Atomtransferreagenzien zu Alkinen in der Goldkatalyse. Anhand der Umwandlung von N‐(2‐Alkinylphenyl)‐sulfoximinen zu 3H‐Indol‐3‐onen wird gezeigt, dass die Sulfoximinfunktionalität dazu in der Lage ist, unter Ausbildung des α‐Imino‐Goldcarbens zunächst die Stickstoffeinheit selektiv auf das Alkin zu übertragen, welches dann in einem zweiten Schritt durch das freigesetzte Sulfoxid in einem pseudo‐intramolekularen Mechanismus oxidiert wird ‐ eine Besonderheit, die diese Arbeit mechanistisch von früheren Studien unterscheidet. Eine Kombination aus umfangreichen experimentellen und theoretischen Studien liefert Beweise für den zugrundeliegenden Mechanismus. Da keine externen Reagenzien für die 1,2‐Difunktionalisierung des Alkins erforderlich sind, wird eine Vielzahl funktioneller Gruppen bei der Umwandlung toleriert, so dass die gewünschten 3H‐Indol‐3‐one in meist guter Ausbeute erhalten werden. Darüber hinaus wurde gezeigt, dass es möglich ist, unsere Methodik mit weiteren Transformationen des 3H‐Indol‐3‐on Kerns in Eintopfverfahren zu kombinieren, was einen einfachen Zugang zu C2‐quartären Indolin‐3‐on Strukturen ermöglicht.

Published: December 2024

Photochemical transformation represents an attractive pathway for the conversion of earth‐abundant resources, such as H2O, CO2, O2, and N2, into valuable chemicals by utilizing sunlight as an energy source. Recently, two‐dimensional conjugated metal–organic frameworks (2D c‐MOFs) have emerged as the focal points in the field of photo‐to‐chemical conversion due to their advantages in light harvesting, electrical conductivity, mass transport, tunable electronic and porous structures, as well as abundant active sites. In this review, we highlight various physical and chemical features of 2D c‐MOFs that can contribute to enhanced photo‐induced exciton generation, charge transport, proton migration and redox catalysis. Then, the existing strategies to integrate suitable light absorbers and/or co‐catalysts onto 2D c‐MOFs for photochemical transformations (with a particular focus on H2 evolution, CO2 reduction and O2 reduction) have been discussed. Finally, the challenges and opportunities of using 2D c‐MOFs in other photochemical applications (e.g., N2 fixation, organic synthesis, and environmental remediation) are assessed.

Published: December 2024

Compared to near‐neutral electrolytes (pH=3–6), Zn||Mn batteries in acidic environments can achieve voltages up to ~2 V. However, high proton concentrations raise concerns about Zn anode stability. Current strategies for inhibiting hydrogen evolution corrosion (HEC) on the anode in Zn‐based batteries mainly focus on the near‐neutral electrolytes. To supplement this gap, we developed a conversion‐type interphase strategy using phosphate, sulfate precipitation, and phytic acid modification layers for Zn anodes to demonstrate the potential of Zn anode to operate in acidic electrolytes. This approach enables stable Zn stripping/plating at pH=2.2 for over 3,600 h and 400 h at 1 mA cm−2/0.5 mAh cm−2 and 20 mA cm−2/10 mAh cm−2. Benefiting from stable Zn electrodes, the electrolytic Zn||Mn batteries can operate at 1.90 V. To show more harsh scenarios, the seawater‐based 0.25 Ah‐scale Zn||Mn pouch cells can be assembled with a practical energy density of 57.4 Wh  kg‐1 cell. Significantly, we analyze and emphasize that seawater holds promise as an alternative to deionized water for electrolyte solvents due to its energy and economic effectiveness. This strategy has motivated to expand the working pH range of metal anodes and provides the rational design for grid‐scale energy storage technologies.

Published: December 2024

The performance of solid‐state lithium‐metal batteries (SSLMB) is often constrained by the low ionic conductivity, narrow electrochemical window, and insufficient mechanical strength of polyethylene oxide (PEO)‐based electrolytes. Inspired by the soft‐outside, rigid‐inside structure of starfish, we designed multifunctional “starfish‐type” composite polymer electrolytes (CPEs) using electrospinning technology. These CPEs feature a three‐dimensional rigid skeleton network composed of polyacrylonitrile/metal–organic frameworks/ionic liquids (PAN/MOFs/ILs), creating continuous and efficient Li+ transport channels: MOFs impart rigidity, PEO acts as a cushioning outer layer to enhance interfacial compatibility, and ILs reduce interfacial resistance. The resulting CPEs exhibited excellent ionic conductivity (4.37×10−4 S cm−1), a wide electrochemical window (5.34 V), uniform lithium‐ion flux, and a high transference number (0.69). Leveraging these synergistic advantages, the Li/CPEs/Li symmetric cell demonstrated outstanding dendrite suppression for over 1300 hours, and the LiFePO4/CPEs/Li cell retained 90.1 % capacity after 2100 cycles at 1.0 C, which is the best performance reported for SSLMB with MOF/PEO. The formation of multi‐component solid‐electrolyte interphase and its role in stabilizing lithium metal cycling were systematically elucidated through theoretical simulations and spectroscopic analysis. This nature‐inspired design provides a promising strategy for the development of stable solid‐state electrolytes with extended lifespans.

Structural modification is an advanced strategy to improve the biological activity of selected compounds and is effectively used to overcome the adverse properties of phytochemicals (e.g., curcumin), such as poor bioavailability and solubility, which limit their clinical use. Considering the fact that ferrocene is a very good candidate for organometallic derivatization of natural products, we have synthesized six new ferrocenylpyrazole analogs of curcumin 8–13. The new compounds were characterized by FT‐IR, 1H, and 13C NMR spectroscopy and mass spectrometry (ESI‐MS, HRMS), and their antioxidant and electrochemical properties as well as their biological activity were investigated. The best antioxidant activity evaluated with the DPPH assay was shown by compound 13, but it was lower than the activity achieved by curcumin. The prepared compounds showed no activity against the Gram‐positive and Gram‐negative bacteria tested, but the pyrazoles 8, 10, and 11 and the β‐diketone precursors 5, 6, and 7 caused weaker inhibition of the growth of the yeast Candida utilis compared to nystatin. The higher antiproliferative activity in tumorous Hepa 1–6, HeLa, and MCF‐7 cells compared to normal HaCaT and CHO‐K1 cells was achieved by 10, 12, and 13. Compound 12 showed the strongest inhibitory effect in HeLa cells with an IC50 value of 25.20 μM, while the proliferation of normal cells was significantly less affected. In view of the higher selectivity index, compounds 10 and 12 could be considered for further research in the sense of therapeutic use in neoplasms of reproductive tissue.

Two triazine‐cored BODIPY trimers (Compounds 6 and 12) were synthesized and well characterized using 1H NMR, 13C NMR, 11B NMR, 19F NMR, FT‐IR, and high‐resolution mass spectral analysis. The photophysical, computational, and in vitro anticancer studies of the synthesized compounds were comprehensively evaluated along with previously reported phenylene‐BODIPY trimer (Compound 1). The photophysical studies indicated that the triazine‐cored BODIPY trimers exhibited a slight bathochromic shift compared to the phenylene‐cored trimer. Density functional theory (DFT) calculations suggest that the order of stability of the BODIPY trimers was 1 > 6 > 12. The anticancer efficacy of the BODIPY trimers was investigated against human breast adenocarcinomas cell line MDA‐MB‐231 and mouse embryo fibroblast cell line NIH/3T3 through in vitro cytotoxicity assay. All the BODIPY trimers exhibited elevated cytotoxicity towards cancer cells while displaying lesser cytotoxicity towards normal cells. Compound 6 showed the highest cell death potential with an IC50 value of 27.02 μM, which is twice higher than that of the chemotherapeutic drug cisplatin. The triazine‐cored BODIPY trimers demonstrated superior cytotoxicity against cancer cells in comparison to their phenylene‐cored counterparts. The enhanced cytotoxicity of the triazine‐cored trimers suggests that the triazine core plays a crucial role in enhancing their therapeutic efficacy. This result underscores the potential of triazine‐cored BODIPY trimers as promising anticancer agents.

A series of new mixed‐ligand Cu (II) complexes, that is, [Cu (SB)(py)]ClO4 (1), [Cu (SB)(bpy)]ClO4 (2), and [Cu (SB)(phen)]ClO4 (3), were synthesized and characterized. In these complexes, SB represents a new unsymmetrical Schiff base ligand that was formed from 1:1 condensation of 3‐nitrosalicylaldehyde with ethylenediamine. Single‐crystal X‐ray crystallography (SCXRC) was used to determine the crystal structure of (1). Molecular docking and ADMET tools were used to examine the anticancer potential of the synthesized complexes on the proteins of human colorectal (HCT116) (PDB ID: 3ruk), lung (A549) (PDB ID: 4zxt), and breast (MCF7) (PDB ID: 4zvm) cancerous cells. Three types of chemical drugs, that is, 5‐fluorouracil for breast cancer, capecitabine for human colorectal cancer, etoposide for lung cancer, and one medicinal plant, turmeric (curcumin), were also examined. The results of molecular docking showed that complex (3) had the best performance. According to the comparative outcomes of the in silico ADMET evaluations, the complexes and the SB ligand may belong to the category of drug‐like compounds.

Two‐dimensional (2D) Eu‐Bi12O17Cl2 nanosheet binary composites modified by Bi2S3 nanocrystals were constructed at room temperature using a simple in situ anion‐exchange strategy with pure carbon disulfide as a direct sulfur source. The method is simple to prepare, energy efficient, and easy to handle compared to conventional treatments. These biphasic composites were thoroughly characterized by a batch of analytical techniques. XRD, FT‐IR, Raman, TEM, and XPS spectroscopies verified the coexistence of the two components in the composites, with Bi2S3 uniformly distributed in irregularly shaped nanocrystals of Eu‐Bi12O17Cl2 nanosheets to form intimate interfacial contacts in the heterojunction domain. In addition, oxygen vacancies can be created during the vulcanization process. The synthesized Bi2S3/Eu‐Bi12O17Cl2 composites exhibit high photocatalytic efficiency for CO2 as well as high selectivity for CO under visible‐light irradiation. A feasible photocatalytic mechanism was also proposed and tested for reusability. This study reveals the construction of robust Bi2S3‐containing composites with sufficient oxygen vacancies and enhanced photocatalytic capabilities under moderate conditions.
Symmetry Breaking in Supramolecular Gel Condensation
Authors: Sahoo Pathik
Published: December 2024

Supramolecular condensation during cooling cycles often transitions through multiple metastable phases before achieving a stable crystalline state. Metastability arises from various competing parameters like symmetrical arrangement, and supramolecular bonding and manifests at different temperatures. Symmetrical physical arrangements can minimize vibrational energy and stabilize the systems at higher temperatures. Further cooling promotes directional supramolecular bonding, such as charge‐assisted hydrogen bonding, resulting in molecular periodicity within metastable structures. Frustration occurs when weaker van der Waals bonds form during further cooling, propagating perpendicularly to stronger one‐dimensional charge‐assisted hydrogen bonds and disrupting lateral periodicity in certain solvents. This makes parallel 1D fibers slidable, adding flexibility to the gel fiber. Eventually, some supramolecular systems attain thermodynamically stable crystalline states by perfectly arranging all the molecules. Throughout the process, metastability results from different symmetrical arrangements, and each rearrangement alters the supramolecular structure‘s symmetry, generating new physicochemical properties. Different supramolecular gels uniquely break symmetry, which can be monitored through various techniques. This perspective analyzes supramolecular thermoreversible, reverse thermal, liquid crystalline, thixotropic, and antisolvent‐induced gels to illustrate spontaneous symmetry reduction processes. Reaching a suprasymmetry condensate can classify big data and be applied in unconventional analogue computing or data storage.

The primary aim of this concept is to point the overlooked critical issues, and summary the crucial roles of regulating the electric double layer (EDL), zinc ion transfer number and electrolyte design, thereby enhancing the stability of zinc metal anodes and expediting the commercialization of aqueous zinc‐ion batteries.Aqueous zinc‐ion batteries (AZIBs) are received intensive attention for their inherent safety, economic feasibility, competitive electrochemical performance, and environmental friendliness. However, the rampant side reactions such as dendrite growth, hydrogen evolution, corrosion, and passivation of zinc metal anode seriously hinder the stability of AZIBs. This concept is aimed to enhancing the practical viability of AZIBs, with a particular focus on the stability of zinc metal anodes. Here, we summarized the strategies for achieving high reversibility zinc metal anode, and points out the shortcomings that still exist in current research. Then the crucial role of regulation electric double layer (EDL), zinc ion transfer number and electrolyte design is summarized in detail. Finally, we consider that the design of zinc anode should focus more on practicality and commercialization, and provide a perspective for the future development direction of zinc anode. We hope to provide an inspiration for the design of stable zinc metal anodes in AZIBs from this concept.

Published: December 2024

The fast‐moving consumer goods (FMCG) sector plays a crucial role in shaping consumer behaviour and supporting the sustainable development goals (SDGs), particularly in emerging markets like Ho Chi Minh City (HCMC), Vietnam. This study investigates the impact of green marketing activities such as green brand positioning (GBP), green product innovation (GPI), green distribution (GRD), green pricing (GRP) and green advertising (GRA) on consumer purchase intentions for green products in the FMCG sector. It also explores the moderating role of competitive intensity (COI) in these relationships. Data were collected from 340 consumers in HCMC, with 291 valid responses analysed using SmartPLS. The findings reveal a positive relationship between green marketing strategies and consumer purchase intentions. COI was not found to moderate the effects of GBP, GRA on consumer's purchase intentions for green products in HCMC. These insights highlight the importance of green marketing in promoting sustainable consumer behaviour, suggesting that FMCG companies in HCMC can enhance environmental sustainability by offering eco‐friendly products and aligning their marketing strategies with SDG 12 (Responsible Consumption and Production) and SDG 13 (Climate Action). This study contributes to the academic literature by addressing gaps in our understanding the interplay between green marketing and COI in emerging markets.
From Prayer to Practice: Children's Religious Understanding and Outgroup Prosocial Behaviours

Published: December 2024

In a religiously diverse world, understanding how young children perceive and interact with peers from other religious groups is pivotal for promoting harmony from an early age. The study examines how children's understanding of an outgroup religion is associated with their prosocial behaviours towards children from that religion. Conducted with 210 children aged 3–6 years (mean = 4.19 years; 50.7% boys) from the majority religion (Catholic) in state schools in Malta, we assessed children's religious understanding through identification of ingroup religious symbols, and prayer. Additionally, we measured children's outgroup (i.e., Muslim) religious understanding through outgroup prayer. Children's prosocial behaviours were assessed through their costly giving of stickers to outgroup children. Findings indicate that outgroup religious understanding moderated the link between children's religious understanding and outgroup giving. Specifically, outgroup religious understanding dampened the association between ingroup religious understanding and outgroup giving for children with higher ingroup religious understanding. Implications of children's outgroup religious understanding on prosocial behaviours are discussed.
Prepare for best possible experience, outcome during NCAA enforcement investigations

Published: December 2024

Hall of Fame men's basketball coach Jerry Tarkanian once famously said, “The NCAA is so mad at Kentucky they’re going to give Cleveland State another year of probation.” Tarkanian's implication that the NCAA engaged in selective and inconsistent enforcement of its rules has been accepted as fact by many through the years. But the truth is that the goal of the NCAA enforcement staff during its investigations is to follow the information wherever it may lead, even if that means closing a case without alleging any violations.

Extant literature suggests that personal values influence consumers' choice, intention, and preference for sustainable and environment‐friendly products. By adopting a replicative and systematic‐cum‐quantitative approach, this bibliometric review attempts to map the existing literature, which jointly studies personal values and sustainable consumption. Choosing from the bibliometric toolbox, we employed a diverse set of analyses such as performance analysis, co‐authorship analysis, cartographic analysis, thematic mapping, and thematic evolution on a refined dataset comprising 419 peer‐reviewed journal articles from 187 journals. The findings of this synthesis point to six distinct topical clusters to orchestrate and present the intellectual structure, along with identifying top contributors and constituents in the domain. We also map the themes and chart the evolution using the Sankey diagram on Bibliometrix‐R. In addition, a three‐dimensional TMC framework is adopted to outline avenues for future research. Furthermore, we suggest implications for theory and practice and elucidate the limitations.

Multipotent mesenchymal stromal/stem cells (MSCs) refer to a population of stem cells that exhibit distinct progenitor cell characteristics including the potential for differentiation into a wide range of cell types. MSCs have become a promising candidate for cell therapy and tissue regeneration due to their unique properties, such as their ability to differentiate into multiple cell types, their capacity for expansion, self‐renewal, and immune‐regulatory effects. However, reports have brought attention to thrombosis‐related complications associated with MSCs therapy in the last decade. As tissue factor (TF) is a powerful coagulation activator expressed by MSCs that stimulates the extrinsic coagulation pathway, we investigated the thrombotic properties of human umbilical cord MSCs (HUCMSCs) after knocking out the TF gene. MSCs populations that obtained from umbilical cord were cultured and expanded in the appropriate medium cell culture. The identity of the MSCs was verified through flow cytometry, and their ability to differentiate into osteogenic and adipogenic lineages. Two gRNAs for Exons 1 and 2 of the TF gene have been designed and cloned into px458 vector's backbone (pSpCas9 (BB)−2A‐GFP). Following transfecting of gRNAs into HUCMSCs and successfully knocking out the TF gene using GAP‐PCR, the impact of normal and knockout HUCMSCs on coagulation was assessed through prothrombin time (PT), D‐dimer level, clotting time (CT), and turbidity assay. Furthermore, the impact of TF knockout (TFKO) on MMP19 expression was assessed. Our results revealed that the PT was prolonged and D‐dimer level was decreased in TFKO group compared to normal HUCMSCs. These findings suggest that TF gene plays a crucial role in regulating coagulation in HUCMSCs. Also, a significant reduction in MMP19 expression was observed within the TFKO group.

The present investigation assesses ursodeoxycholic acid's efficacy (UDCA) as an ACE2 activator against gamma irradiation through activating the renin‐angiotensin system's (RAS) beneficial axis, ACE2/Ang‐(1–7)/Mas1 via its profitable influence on inflammation, oxidative stress, and neuronal damage caused by irradiation (IRR). Four groups of rats were treated as follows: control group, group receiving UDCA (100 mg/kg/day) for 14 days by gavage, group irradiated at 6 Gy, and group receiving UDCA post‐irradiation for 14 days. The results revealed that gamma‐irradiation (6 Gy) caused a substantial drop in the cerebral ACE2/Ang‐(1–7)/Mas1 axis and remarkably increased the expression of cerebral inflammatory mediators: tumor necrosis factor‐α (TNF‐α), nuclear factor kappa‐B (NF‐κB), interleukin‐6 (IL‐6) and interleukin‐1β (IL‐1β) combined with significant elevation in cyclooxygenase‐II (COX‐II), (NADPH) oxidases (NOX4), lipooxygenase (LOX) activities and nitric oxide (NO) content. Moreover, it greatly enhanced the reduction in N‐methyl‐d‐aspartate (NMDA) level, while dramatically increasing gamma‐aminobutyric acid (GABA) level and neuronal nitric oxide synthases (nNOS) enzyme activity in cerebral tissue homogenate. Irradiated rats’ brain sections underwent histological investigation using hematoxylin and eosin staining, which revealed cellular damage and a pathological appearance. The administration of UDCA inverts these unusual alterations. In conclusion, UDCA treatment efficiently normalizes the above‐mentioned pathological abnormalities and avoids the development of IRR‐associated neurological dysfunction by upregulating the beneficial axis of RAS in the brain. Hence, ursodeoxycholic acid presents a novel option for patient care during radiotherapy.

Acrylic acid yield (AAY) is a key quality index in production process of acrylic acid. Meanwhile, AAY has been considered as direct characterization of productivity. Aiming at the difficulty of online measurement of AAY in acrylic acid process, a soft sensing model of AAY based on autoencoder long short‐term memory neural network (AE LSTM NN) applying Savitzky–Golay and ReliefF method is presented in this paper. Firstly, Savitzky–Golay method with denoising effect is adopted to remove industrial noise in measurement. Then, ReliefF algorithm is developed to compress characteristic variables from the result of denoising. Finally, AE LSTM is employed to predict the AAY in acrylic acid process. In contrast to LSTM, support vector machine, and artificial neural network, the root mean square error (RMSE) of the provided method is 0.0954, mean absolute error (MAE) is 0.0757, mean absolute percent error (MAPE) is 0.09%, and maximum absolute error (MaxAE) is 0.3236, which shows validity and superiority.

Cocrystallization of trans‐aconitic acid (TACA) and isonicotinamide (INA) using liquid assisted mechanochemical grinding results in a unique supramolecular hydrogen‐bonded organic framework (HOF) system encapsulating various organic solvents (liquid guest) with the formation of channel inclusion compounds. Dimension and shape of the framework is dependent on the solvent used during liquid assisted grinding (LAG). Although crystal structure of the cocrystal (TACA) ⋅ (INA)2 ⋅ (H2O)@(INA)0.5 has been determined by Single Crystal X‐ray diffraction (SCXRD), crystal structures of 3 cocrystal HOFs were determined by microcrystal electron diffraction (MicroED) and synchrotron X‐ray diffraction due to lack of suitable single crystal. PXRD analysis confirms isostructurality of various host‐guest systems; whereas guest incorporation as well as stability of the HOFs were further confirmed using thermogravimetric analysis. This study demonstrates that the framework of HOFs can be tuned by varying solvent molecules used during LAG.

Published: December 2024

Molecular design of dual‐fluorescent probes requires precise adjustment of the energy levels of two excited states and the energy barrier between them. While the hybridized local and charge‐transfer (HLCT) state has been recently focused as an important excited state for high emission efficiency with a tunable energy level, a dual emission involving the HLCT state has been only achieved with the excited‐state intramolecular proton transfer (ESIPT) system. Here, a series of dual‐fluorescent molecules involving an HLCT excited state with the excited‐state conjugation enhancement (ESCE) motif is presented as the first case. The energy level of the HLCT state has been adjusted by changing substituents and solvents, separately from the ESCE energy level. The HLCT‐ESCE molecular design with tunable fluorescence properties proposes a new strategy for the development of advanced fluorescent probes.

Background

Epidemiological findings regarding the association between asthma and the risk of colon cancer (CC) are inconsistent. The causality and potential molecular mechanisms underlying asthma, eosinophil count, and CC remain unknown.

Methods

We performed Mendelian randomization (MR) analysis to investigate the causality between asthma and CC and attempted to demonstrate that asthma indirectly affects CC mediated by eosinophil count through mediation analysis. Sensitivity analyses and multivariable MR were performed to test the robustness of our findings. Multiple bioinformatics tools were applied to further investigate the underlying mechanisms related to eosinophils that contribute to the pathogenesis of both asthma and CC.

Results

MR with mediation analyses suggested that eosinophil count may play a role in the mechanism through which asthma reduces the risk of CC. Our bioinformatic analyses identified PPP1R14A as a potential therapeutic target and an eosinophil‐associated biomarker for CC patients. Higher expression of PPP1R14A may be associated with a poorer prognosis in CC patients. Additionally, the lysosome pathway emerges as a shared eosinophil‐related pathway in both asthma and CC.

Conclusions

Eosinophils may contribute to a lower risk of CC in patients with asthma. PPP1R14A is a potential therapeutic target and biomarker for CC.

Published: December 2024

The critical micelle concentration is an important property of supramolecular detergents. Two dynamic light scattering approaches have been developed for critical micelle concentration analysis, i. e., concentration‐dependent light scattering intensity analysis and diffusion coefficient analysis. Their utility as complementary tools for a reproducible determination of critical micelle concentration remains to be clarified. Herein, we address the question which of the two approaches is more suitable for obtaining reproducible critical micelle concentration values. We systematically compare both approaches in context with common detergent classes and benchmark utility by means of literature values. Our results show that the diffusion coefficient analysis delivers reproducible critical micelle concentration values in aqueous solutions. Our findings outline a roadmap to guide the critical micelle concentration analysis of detergents by dynamic light scattering in the future.

Published: December 2024

Artificial photosynthesis, encompassing the photocatalytic generation of H2 and CO2 reduction innovations, seems to be a highly promising approach. This is due to its ability to efficiently transform CO2 into hydrocarbon fuel and valuable chemical products using solar energy as a direct energy source. This will simultaneously help to mitigate global warming and energy shortage issues. Chalcogenide‐based semiconductors have recently gotten a lot of attention as an important area of research for photocatalytic H2 production and CO2 conversion, owing to their low band gap energy, suitable band structures, and a great photoresponsivity spectrum. Modifying chalcogenides into their heterostructures could be a great way to solve problems like photo corrosion and carrier recombination. Therefore, this review summarized a series of different modifications of chalcogenides and recent developments in their photocatalytic and photo electrocatalytic performance, particularly in H2 production and CO2 conversion. Lastly, we discussed the challenges, limitations, areas for development, and future prospects of chalcogenides and their heterostructures capable of utilizing visible light to produce H2 gas and reduce CO2.
