AbstractThe growing concern over implant‐associated infections motivates the development of novel antibacterial coatings for medical devices as an effective strategy in reducing the occurrence of IAI. Polyelectrolyte multilayers (PEMs) incorporating metal/metal oxide nanoparticles (NPs) as antimicrobial components receive special attention for their ability to coat diverse surface types and low potential to induce antimicrobial resistance. This study investigates the potential of poly(amino acid) multilayers consisting of poly‐L‐lysine and poly‐L‐glutamic acid with embedded silver (PEMAg) or copper oxide (PEMCuO) deposited on titanium surfaces for the coating of medical surfaces. The results of the quartz crystal microbalance with dissipation, scanning electron microscopy, and electron dispersive spectroscopy show that both types of NPs are successfully incorporated in the PEM and deposited over the entire coated surface. The incorporation of NPs in PEM prevents the burst release. The viability of MG‐63 cells is higher than 70% on all investigated PEMs, confirming their biocompatibility. PEMCuO shows better biofilm prevention compared to PEMAg, entirely preventing Pseudomonas aeruginosa biofilm and allowing the formation of only weak Staphylococcus aureus biofilm. The results obtained confirm the high potential of poly(amino acids) multilayers with embedded metal/metal oxide NPs as biocompatible antimicrobial coatings for medical devices.

Published: December 2024

AbstractAll‐solid‐state lithium–sulfur batteries (ASSLSBs), a promising alternative to liquid lithium–sulfur batteries, are expected to alleviate the shuttle effect, reduce material loss, and achieve a compact structure. However, ASSLSBs face challenges in ionic conductivity and stability of solid electrolytes, optimization of sulfur cathodes, and electrolyte/electrode interfaces. This review summarizes recent research progress and strategies addressing these issues, focusing on oxide and sulfide‐based electrolytes. Furthermore, it emphasizes the crucial role of rational optimization of sulfur cathode materials in composition, structure, and microstructure for constructing efficient ion/electron transport networks, and explores methods to solve chemical/electrochemical and physical interface issues. Additionally, it addresses challenges associated with the lithium anode and its interface problems, covering strategies, such as lithium alloy formation, 3D electrode architecture, and interfacial buffer layer implementation. These approaches aim to enhance the stability and performance of the lithium anode in ASSLSBs. Finally, this review highlights the significance of in situ characterization techniques for revealing reaction mechanisms, providing insights into phase composition, elemental chemical states, and dynamic structural transformations within the batteries, crucial for developing high‐performance ASSLSBs.

Published: December 2024

AbstractCombination therapy has become a promising strategy for promoting the outcomes of anti‐programmed death ligand‐1 (αPD‐L1) therapy in lung cancer. Among all, emerging strategies targeting cancer metabolism have shown great potency in treating cancers with immunotherapy. Here, alteration in glucose and copper metabolisms is found to synergistically regulate PD‐L1 expression in lung cancer cells. Thus, an intelligent biomimetic nano‐delivery system is synthesized by camouflaging lung cancer cell membranes onto glucose oxidase‐loaded Cu‐LDHs (CMGCL) for cancer metabolism targeted interference. Such novel nanomedicine is able to induce lung cancer cell cuproptosis and PD‐L1 upregulation significantly via self‐amplified cascade reactions. Meanwhile, with a decent cancer cell membrane coating, CMGCL exhibited great biosafety, tumor‐targeted efficiency and anti‐tumor effects in LLC lung tumor‐bearing mice models. Additionally, a combination of CMGCL can sensitize the therapeutic effects of αPD‐L1, substantially promoting tumor inhibition in both subcutaneous and lung metastasis LLC‐bearing mice models. Overall, these findings highlight the potential connections between glucose metabolism and cell cuproptosis, offering a promising approach for treating lung cancer by integrating starvation, cuproptosis, and immunotherapy.

Published: December 2024

AbstractIntegrating pain perception into wearable electronics or humanoid robots within artificial neuromorphic systems is highly desirable, as it allows for the identification of harmful stimuli and the generation of appropriate responses. In this study, flexible pain perception synaptic transistors is developed based on solid state ionic‐liquid‐cross‐linking‐poly (4‐vinylphenol) (IL‐c‐PVP) electrolyte and IGZO channel with excellent electrical and photoelectric performances. Typical transistor synaptic plasticity, such as paired pulse facilitation, short‐term memory, and long‐term potentiation, is realized with the electrolyte comprising 40% ionic liquid, featuring a large electric‐double‐layer capacitance of 0.65 µF cm−2 at 20 Hz. In addition, due to the low ion mobility and large capacity of the electrolyte, alongside the persistent photoconductivity to UV light and the high electron carrier mobility of the IGZO, the fabricated synaptic transistors demonstrated excellent pain perception capabilities, including pain threshold, peripheral sensitization, desensitization and central regulation in response to both electrical and optical stimuli with ultralow energy consumption (≈1.3 fJ per event) and desirable mechanical flexibility. Moreover, classical Pavlovian pain conditioning is successfully simulated through electro‐optical co‐modulation, and visual imaging in the curved state is demonstrated, highlighting the potential applications of these synaptic transistors in biomimetic nervous systems.

Published: December 2024

AbstractInherent rigidity of high‐performing inorganic thermoelectric materials constrains their potential applications as flexible power sources for the wearable electronics. Deformation within the elastic region ensures the reservation of a material's initial functionalities, motivating the current work to focus on the elasticity enhancement of Ag2Te thermoelectric. Ag2S‐alloying results in an observable reduction in the modulus of Ag2Te1‐xSx alloys (x ≤ 0.3), which thereby enables not only a great increase in the elastic strain but also a significant plasticization of the alloys, allowing the plastic deformability by the rolling at a temperature of ≈120 °C. Such a plastic deformation‐induced improvement in yield strength leads to a further improvement of the elastic strain up to 1.8%, corresponding to ≈200% enhancements as compared to pristine Ag2Te (≈0.6%). Eventually, the multi‐pass hot‐rolled Ag2Te0.9S0.1 film achieves a full recoverability in transport properties even after elastic bending within a tiny radius of ≈3 mm for 100 000 times and a power density as high as ≈25 W m−2 in six‐leg device. This work robustly demonstrates a universal strategy to advance the recoverable bendability of inorganic thermoelectric materials for flexible applications.

Published: December 2024

AbstractIonogel polymer electrolyte (IPE), incorporating ionic liquid (IL) within a polymer matrix, presents a promising avenue for safe quasi‐solid‐state lithium metal batteries. However, sluggish Li+ kinetics, resulting from the formation of [Li(anion)n]−(n−1) clusters and the occupation of Li+ transport sites by organic cations, limit their practical applications. In this study, we have developed zwitterionic bottlebrush polymers‐based IPE with promoted Li+ conduction by employing poly(sulfobetaine methacrylate)‐grafted poly(vinylidene fluoride‐co‐chlorotrifluoroethylene) (PVC‐g‐PSBMA) bottlebrushes as matrices of IL. The grafted zwitterionic side chains greatly facilitate the dissociation of [Li(anion)n]−(n−1) clusters to produce more movable Li+. Moreover, the positively charged −NR4+ groups in zwitterionic side chains effectively restrain anions migration, while the negatively charged −SO3− groups immobilize IL cations, preventing them from occupying Li+ hopping sites and reducing the energy barrier for Li+ migration. These synergistic effects contribute to a notable ionic conductivity (7.5×10−4 S cm−1) and Li+ transference number (0.62) of PVC‐g‐PSBMA IPE at 25 °C. As a result, PVC‐g‐PSBMA IPE enables ultralong‐term (over 6500 h) reversible and stable Li plating/stripping in Li||Li symmetric cells. Remarkably, the assembled Li||LiFePO4 full batteries demonstrate unprecedented cycling stability of more than 2000 cycles with a superior capacity retention of 93.7 %.

Published: December 2024

AbstractMetal oxide (MO)‐based chemiresistive sensors have great potential in environmental monitoring, security protection, and disease diagnosis. However, the thermally activated sensing mechanism in pristine MOs leads to high working temperature and poor selectivity, which are the main challenges impeding practical applications. Precise modulation of the band structure at the heterojunction interfaces of MOs offers the opportunity to unlock unique electrical and optical properties, enabling us to overcome these challenges. Metal–organic frameworks (MOFs) with tunable structures are promising materials for aligning the energy levels at the heterojunctions of MOs. Herein, we report the energy‐level structural engineering of MO@MOF heterojunctions to optimize chemiresistive sensing performance. The interface was flexibly modulated from a straddling gap to a staggered gap by ‐NH2 functionalization of TiO2@(NH2)x‐MIL‐125, varying x from 0 to 1 and 2, respectively. TiO2@(NH2)x‐MIL‐125 combines the advantages of MOs and MOFs to synergistically improve gas‐sensing properties. As a result, TiO2@NH2‐MIL‐125 is the first light‐activated material to detect NO2 at 1 ppb with a response time of < 0.3 min at room temperature. It also exhibited excellent selectivity and long‐term stability. Our study underscores the potential of energy band engineering in creating high‐performance sensors, offering a strategy to overcome current material limits.

Published: December 2024

AbstractUnderstanding the relationship of competitive adsorption between reactants is the prerequisite for high activity and selectivity in heterogeneous catalysis, especially the difference between the adsorption energies (Eads) of two reactive intermediates in Langmuir–Hinshelwood (L−H) models. Using oxidative dehydrogenation of hydrogen sulfide (H2S‐ODH) as a probe, we develop various metal single atoms on nitrogen‐doped carbon (M‐NDC) catalysts for controlling Eads‐H2S, Eads‐O2 and investigating the difference in activity and selectivity. Combining theoretical and experimental results, a Sabatier relationship between the catalytic performance and Eads‐O2/Eads‐H2S emerges. Mn‐NDC as the optimal catalyst shows excellent H2S conversion (>90 %) and sulfur selectivity (>90 %) in a wide range of O2 concentrations over 100 h. Such a high‐efficiency performance is attributed to appropriate Eads‐H2S and Eads‐O2 on Mn‐N4 sites, boosting redox cycle between Mn2+ and Mn3+, as well as preferential formation of sulfur. This work provides a fundamental guidance for designing Sabatier optimal catalysts in L−H models.

Published: December 2024

AbstractKomplexe mit einem doppelt reduzierten CO22−‐Liganden (Carbonit), koordiniert zwischen einem Nickel(II)‐Zentrum und einem Übergangsmetall(II)‐Ion (ÜM=Fe, Co, Zn), wurden untersucht. In nicht‐koordinierenden Lösemitteln zeigt der Carbonit‐Ligand ein flexibles Koordinationsverhalten, das mittels NMR‐Spektroskopie und DFT‐Berechnungen untersucht wurde. Speziell der [Ni‐CO2‐Fe]‐Vertreter repliziert in vielerlei Hinsicht das entsprechende Intermediat, das während der CO2‐Umwandlung durch das Enzym [Ni,Fe]‐CODH auftritt (Struktur, spektroskopische Eigenschaften, Reaktivität). Unsere Untersuchungen zeigen, dass Übergangsmetall‐Ionen das Reduktionspotenzial der Carbonit‐Einheit verringern, jedoch deren Tendenz zur C−O‐Bindungs‐Spaltung erhöhen. Dies könnte die Wahl des Eisen(II)‐Ions anstelle von s‐ oder p‐Block‐basierten Lewis‐Säuren als Teil des aktiven Zentrums der CODH erklären.

Published: December 2024

AbstractThis study reports a method for enhancing the functions and properties of traditional organic macrocyclic hosts by fully encapsulating them within a large M9L6 cage to form host‐in‐host complexes. Within the cage host, the macrocyclic organic hosts with electron‐rich aromatic rings, such as cyclotriveratrylene and calix[8]arene, adopt specific orientations enhancing their inherent molecular recognition abilities. Due to the high crystallinity of the M9L6 cage, the guest encapsulation behavior of the host‐in‐host complexes can be observed by X‐ray structural analysis.

Authors: McVeigh Mary Jo 
Published: December 2024

AbstractMothers who experience DFV are often at risk of being epistemically harmed by professional discourses that are mother‐blaming because professionals often overburden them with unrealistic expectations of protecting their children. In addition, children and young people who experience DFV are frequently at risk of being subjected to epistemic injustice by professional discourses that negate them as knowledge generators. Added to this tangle of epistemic misplacement is the wedge that perpetrators drive between mothers and children so they both cannot see each other survivance wisdom and connection to each other. Family‐inclusive/lead therapy that epistemically privileges mothers' and children's survivance wisdom can repair the damage done to them as knowledge generators and to their relationships. This article describes an example of nondeliberative work that highlights family‐inclusive/lead therapy has a place in family intervention post‐DFV.

AbstractA robust, metal‐free and K2CO3‐mediated method has been developed to access highly diversified pyrazole C‐3/4/5 linked 1,3,4‐oxadiazole derivatives through the formation of C−O/C−N bonds in a one‐pot operation. This domino methodology was facilitated by utilizing pyrazole C‐3/4/5 carbaldehydes and benzohydrazides as starting substrates to generate the interesting molecular hybrids with high yields. The photophysical properties were also evaluated of the synthesized derivatives and exhibited good results with more than seven parameters. The fluorescence quantum yield of the pyrazole based 1,3,4‐oxadiazole was reached up to 75 %. The salient features of this approach are diversity‐oriented synthesis, metal‐free strategy, high yields and superior atom economy.
Structure and dynamics of anxiety in people with ASD and ID: A network analysis
Authors: Sáez‐Suanes Gema P. 
Published: December 2024

AbstractAnxiety is a very common mental health disorder in the ASD population. Despite the common comorbidity this association is not well understood. To understand the relationship between anxiety symptoms and ASD in a sample of people with ASD and intellectual disability, a network analysis was carried out. One hundred and twenty‐eight adults (M = 36.63 age, SD = 8,54) were evaluated to know the structure of anxiety symptoms in autism and their relationship with ASD symptomatology. The results showed a single network where both symptomatologies were mixed. Bridging symptoms such as fear of being touched, fear of something bad happening to them, and the need for invariance and anticipation were identified. Moreover, social issues such as difficulty in making friends were associated with anxiety symptoms. Knowing and identifying ASD symptoms that are strongly linked to the anxiety network has important implications for the prevention of anxiety in this case in people with autism and intellectual disabilities.

Published: December 2024

ABSTRACTIn this work, a simple, low‐cost method for fabricating random gain media from Rhodamine B dye solution containing highly‐pure CuO nanoparticles in transparent resin hosts is proposed. The spectroscopic characteristics of the dye solution samples were investigated with varying dye concentrations, along with nanoparticles of different particle sizes and concentrations. The fabricated samples were excited using two laser sources (405 and 530 nm) to record the fluorescence spectra. Our findings indicate that nanoparticles ranging in size from 15 to 78 nm may not have a significant impact on the fluorescence intensity or the peak wavelength at which maximum fluorescence occurs. Additionally, the fluorescence peak width, centered around 595 nm showed minimal sensitivity to the variation in particle size. The optimal concentration of nanoparticles in the dye solution was determined based on the optimum values of scattering spectral width and anisotropy parameter. Subsequently, the gain coefficient was calculated and correlated with these two parameters. It was found that the samples with the highest fluorescence intensity can be achieved using dye dissolved in transparent resin at a molar concentration of 5 × 10−5 M, containing 0.03–0.04 mg of CuO nanoparticles with a particle size of 78 nm.

Published: December 2024

ABSTRACTEmbarking on a journey to decipher the role of active sites in the detection and removal of toxic mercury(II) ions from polluted water, the surface of thermally engineered biomass derived carbon matrix NC‐180 was customized with nitrogen atoms. The HR‐TEM and XRD analyses revealed the amorphous nature of Lantana camara derived carbon material with small spherical flakes embedded in it. XPS analysis indicated the presence of pyrrolic, pyridinic, and graphitic N atoms, which was further confirmed by FT‐IR analysis. The material shows quenching effect in presence of Hg2+ ions resulting in the “turn off” effect with a detection limit of 7.2 nM. The activity of NC‐180 was recovered through “turn on” effect in the presence of L‐cysteine. Furthermore, the mystery of binding of mercury(II) ions with N‐sites is clarified through its comparison with other materials bearing sulfur and oxygen functional groups designated as AC‐180, SC‐180, and NSC‐180. The conclusive evidence for efficient binding of nitrogen sites in NC‐180 with mercury(II) ions is derived from various analyses, including 1H‐NMR, FT‐IR, XPS, and density functional theory. Notably, sustainability is achieved through utilization of toxic weed L. camara for the preparation of this selective carbon material for detection and adsorption of mercury(II) ions.
The Role of Sustainability Performance on Financial Resilience During Crisis

Published: December 2024

ABSTRACTThe aim of this study is to investigate the association between sustainability performance (which is proxied by ESG score) and a firm's financial resilience in crisis conditions. This study is triggered in response to the COVID‐19 pandemic as a global crisis setting. By focusing on five ASEAN countries, namely Indonesia, Malaysia, Singapore, Thailand, and the Philippines, this study argues that companies with higher ESG performance will be more financially resilient during a crisis. This study uses several measurements of the company's financial resilience, both measures that utilize share prices and financial ratios from financial statements. The results show that ESG performance is negatively associated with financial resilience. ESG performance is considered less valuable during a crisis because ESG activities consume the company's financial resources. It implies that survival is more important than sustainability during times of crisis. ESG performance is considered to consume a company's financial resources in times of crisis.
