AbstractCircularly polarized luminescence (CPL) materials offer exciting potential due to their unique light properties. However, controlling the color of afterglow emission, a key feature for many applications remains a challenge. Here, a co‐doping strategy is presented for precise control of multicolor CPL afterglow in films. This approach utilizes chiral naphthylphosphoric acid derivatives as energy and chirality transfer donors, commonly used fluorescent dye rhodamine B (RB) and PVA are selected as the acceptor and the polymeric matrix, respectively. Remarkably, the co‐doped films exhibit ultra‐long green circular polarization phosphorescence lasting several seconds with high efficiency (14.23%), lifetime (1025.5 ms), and dissymmetry factor (8.44 × 10−3). Crucially, by adjusting the acceptor content, it can precisely tune the phosphorescence‐to‐fluorescence ratio and achieve multicolor afterglow. This control stems from a combination of Förster resonance energy transfer, chirality transfer, and color‐mixing effects. Furthermore, this approach significantly improves the asymmetry factor of the CPL afterglow by an order of magnitude (5.17 × 10−2). It is anticipated that this straightforward approach to precisely regulating the afterglow color of CPL will provide invaluable insights for the future design of highly efficient and innovative CPL materials.

AbstractSelf‐healing materials that integrate excellent mechanical properties and high healing efficiency meet the requirements of flexible electronic sensors for mechanical flexibility and reliability. In the field of wearable devices, they are of great significance for improving the stability of the equipment and reducing the frequency of replacement. However, the high strength of materials often limits their self‐healing ability. When damage occurs, it will hinder the microstructural adjustment and fluidity of the material at the damaged site, thus negatively affecting the activation and execution of the self‐healing mechanism. In this study, a strength‐toughness and room‐temperature self‐healing triboelectric material is prepared by the dynamic nanoconfinement effect and the quenching effect of ethanol (referred to as the DNCQ strategy). The quenching effect of ethanol improves the aggregation of nanocluster phase, and the constructed nanoconfined network skillfully balances the contradiction between mechanical properties and self‐healing ability. The obtained triboelectric material has high tensile strength (27.1 MPa), toughness (97.9 MJ m−3), and excellent healing efficiency (88.6%). The self‐powered pressure distribution sensing array based on triboelectric materials can accurately reflect the pressure distribution of the object, which has potential application prospects in the field of wearable devices.

AbstractReconstruction of a full‐thickness spongy urethra is difficult because a corpus spongiosum (CS) defect cannot be repaired using self‐healing or substitution urethroplasty. Small extracellular vesicles (sEVs) secreted by urine‐derived stem cells (USC‐sEVs) strongly promote vascular regeneration. In this study, it is aimed to explore whether USC‐sEVs promote the repair of CS defects. To prolong the in vivo effects of USC‐sEVs, a void‐forming photoinduced imine crosslinking hydrogel (vHG) is prepared and mixed with the USC‐sEV suspension. vHG encapsulated with USC‐sEVs (vHG‐sEVs) is used to repair a CS defect with length of 1.5 cm and width of 0.8 cm. The results show that vHG‐sEVs promote the regeneration and repair of CS defects. Histological analysis reveals abundant sinusoid‐like vascular structures in the vHG‐sEV group. Photoacoustic microscopy indicates that blood flow and microvascular structure of the defect area in the vHG‐sEV group are similar to those in the normal CS group. This study confirms that the in situ‐formed vHG‐sEV patch appears to be a valid and promising strategy for repairing CS defects.

Published: July 2024

AbstractPhotoluminescent metallopolymers displaying photo‐stimuli‐responsive properties are emerging as promising materials with versatile applications in photo‐rewritable patterns, wearable UV sensors, and optical encryption anti‐counterfeiting. However, integrating these materials into practical applications that require fast response times, lightweight qualities, fatigue resistance, and multiple encryption capabilities poses challenges. In this study, luminescent photochromic lanthanide (Ln) metallopolymers with rapid self‐healing properties are developed by cross‐linking terpyridine (Tpy)‐ and spiropyran (SP)‐ functionalized polyurethane chains through Ln‐Tpy coordination bonds and H‐bonds among polymer chains. The resulting products exhibit a range of intriguing features: i) photo‐stimuli responsiveness using spiropyran monomers without additional dopants; ii) dual‐emitting performance under UV‐light due to Ln‐Tpy and open‐ring spiropyran moieties; iii) satisfactory mechanical properties and self‐healing abilities from polymer chains; iv) multiple control switches for luminescence colors through photostimulation or feed ratio adjustments. Leveraging these attributes, the developed material introduces novel opportunities for light‐writing applications, advanced information encryption, UV‐sensing wearable devices, and insights into designing multifunctional intelligent materials for the future.

Published: July 2024

AbstractThe growing challenge of poly(ethylene terephthalate) (PET) plastic bottle waste underscores the urgent need for innovative solutions. This study introduces a pioneering approach to repurpose PET waste into valuable electrolytic material for electrochromic (EC) smart windows, presenting a novel strategy to address environmental concerns while advancing technology. Through alkaline depolymerization, disodium terephthalate (DST) electrolyte is derived from PET waste, offering an eco‐friendly and cost‐effective alternative. Integrated with chromogens such as 1‐hexyl‐[4,4′‐bipyridin]‐1‐ium iodide [MV(I)], or 1,1′‐dihexyl‐[4,4′‐bipyridine]‐1,1′‐diium iodide [DVH(I)], or 1,1′‐dihexyl‐[4,4′‐bipyridine]‐1,1′‐diium dihexafluorophosphate [DVH(PF6)], alongside hydroquinone [HQ] and poly(ethyene glycol) diacrylate [PEGDA]: water, novel EC gel‐based devices are fabricated. Notably, ED‐3 exhibits dual‐band absorption across the visible to near‐infrared spectrum, enabling seamless color transitions and exceptional optical contrast. With (ΔT) values of 88.03% at 550 nm and 73.7% at 900 nm, along with a coloration efficiency of 277 cm2C⁻¹ and cyclic stability exceeding 2000 cycles, this innovative approach marks a significant advancement in PET waste upcycling for EC applications. Furthermore, this research contributes to addressing the global challenges of plastic waste pollution and energy consumption, underscoring the transformative potential of sustainable material development.

Published: July 2024

AbstractPubertal research has primarily focused on hypothalamic–pituitary–gonadal axis (HPG) regulation of puberty, though the hypothalamic–pituitary–adrenal axis (HPA) is increasingly considered critical. Heightened HPA function proxied by increasing cortisol levels may play a role in accelerated pubertal timing. However, the extent to which cortisol varies across ages and its relation to pubertal changes in linear growth are less well substantiated. We explored relationships between age, linear growth, adiposity, C‐peptide (proxy for insulin), and cortisol across puberty, and we tested whether higher cortisol levels are associated with earlier ages at menarche and peak height velocity. We utilize longitudinal data (n = 777 urine samples) from Qom females ages 7–14 (n = 46) and test our pre‐registered analysis using Bayesian longitudinal mixed effects models and joint modeling techniques. We find limited evidence supporting the overarching hypothesis that HPA upregulation is associated with pubertal maturation or timing. We find some evidence that HPA upregulation, as proxied by cortisol, may be more clearly related to differences in relative linear growth at early‐mid puberty, as measured by height‐for‐age z‐scores. Transdisciplinary perspectives on puberty, including the assumption that stressors acting via cortisol accelerate pubertal development, are discussed.

AbstractThiourea dioxide (TDO) has been demonstrated to be an efficient reagent for the transformation of aromatic, heteroaromatic, alkenyl and aliphatic aldoximes to respective nitriles in excellent yields. Furthermore, this method has been applied to the synthesis of fungicide cyazofamid from a commercial precursor using TDO as a pivotal dehydrating and reducing reagent. This new procedure offers simple and easily reproducible technique for nitrile synthesis and highlights the synthetic utility of TDO as a versatile reagent in organic chemistry.

AbstractChanges in the rate of self‐directed behavior—a proxy for social tension—offer valuable insights into individuals' experiences of social interactions. Many studies have tested the tension‐reduction hypothesis, whereby grooming is expected to reduce social tension in the grooming partners. However, it is still unclear whether responses to grooming are affected by social factors such as an individual's role or social relationship with their partner, and whether responses are similar for females and males. Focussing on same‐sex grooming in Yakushima Japanese macaques (Macaca fuscata yakui), we analyzed the effects of two social factors on the change in the rate of self‐scratching after receiving grooming: sitting in contact with their partner outside of grooming contexts (as a measure of relationship strength) and rank distance. We collected 10‐min postgrooming and matched‐control focal samples on recipients of grooming. After controlling for postinhibitory rebound effects, grooming reduced scratching in females (suggesting that grooming was relaxing for the receiver), but not in males. In females, this reduction was associated with increased sitting in contact and increased rank distance: being groomed was more tension‐reducing if the grooming partners spent time together outside of grooming contexts, or if their difference in rank was greater and therefore more conspicuous. The reduction effect was mediated by sitting in contact only when females had a higher‐ranking—that is, more dominant and potentially aggressive—groomer. Our findings suggest that not all grooming interactions are perceived as equal, which has implications for its use as an index of relationship quality. To our knowledge, this represents the first study of postgrooming social tension in male Japanese macaques and our results highlight the need for caution when generalizing findings from only one sex to the species level.

Published: July 2024

AbstractImmobilization is a key enabling technology in applied biocatalysis that facilitates the separation, recovery, and reuse of heterogeneous biocatalysts. However, finding a consensus immobilization protocol for several enzymes forming a multi‐enzyme system is extremely difficult and relies on a combinatorial trial‐and‐error approach. Herein, we describe a protocol in which 17 different carriers functionalized with different reactive groups are tested in a 96‐well microtiter plate to screen up to 21 immobilization protocols for up to 18 enzymes. This screening includes an activity and stability assay to select the optimal immobilization chemistry to achieve the most active and stable heterogeneous biocatalysts. The information retrieved from the screening can be rationalized using a Python‐based application CapiPy. Finally, through scoring the screening results, we find the consensus immobilization protocol to assemble an immobilized four‐enzyme system to transform vinyl acetate into (S)‐3‐hydroxybutyric acid. This methodology opens a path to speed up the prototyping of immobilized multi‐enzyme pathways for chemical manufacturing.

Published: July 2024

AbstractZn anode protection in Zn‐ion batteries (ZIBs) face great challenges of high Zn utilization rate (i.e., depth of discharge, DOD) and high current density due to the large difficulty in obtaining an extreme overall RTC (relative texture coefficient) of Zn (002) plane. Through the potent interaction of Mn(III)aq and H+ with distinct Zn crystal planes under an electric field, large‐size Zn foils with a breakthrough (002) plane RTC of 99 % (i.e., close to Zn single crystal) are electrodeposited on texture‐less substrates, which is also applicable from recycled Zn. The ultra‐high (002) plane RTC remarkably enhances cyclic performance of the Zn anode (70 % DOD @ 45.5 mA cm−2), and the DOD is even up to 95 % (@ 28.1 mA cm−2) with an electrolyte additive of polyaniline. Furthermore, MnO2, the by‐product of electrodeposition, is directly used as cathode of both coin cell and pouch battery, surpassing the cyclic performance exhibited by the majority of Zn||MnO2 batteries in previous instances. These results demonstrate the great potential of our strategy for high‐performance, low‐cost and large‐scale ZIBs.

AbstractImproving the slow redox kinetics of sulfur species and shuttling issues of soluble intermediates induced from the multiphase sulfur redox reactions are crucial factors for developing the next‐generation high‐energy‐density lithium‐sulfur (Li−S) batteries. In this study, we successfully constructed a novel molecular electrocatalyst through in situ polymerization of bis(3,4‐dibromobenzene)‐18‐crown‐6 (BD18C6) with polysulfide anions on the cathode interface. The crown ether (CE)‐based polymer acts as a spatial “fence” to precisely control the unique redox characteristics of sulfur species, which could confine sulfur substance within its interior and interact with lithium polysulfides (LiPSs) to optimize the reaction barrier of sulfur species. The “fence” structure and the double‐sided Li+ penetrability of the CE molecule may also prevent the CE catalytic sites from being covered by sulfur during cycling. This new fence‐type electrocatalyst mitigates the “shuttle effect”, enhances the redox activity of sulfur species, and promotes the formation of three‐dimensional stacked lithium sulfide (Li2S) simultaneously. It thus enables lithium‐sulfur batteries to exhibit superior rate performance and cycle stability, which may also inspire development facing analogous multiphase electrochemical energy‐efficient conversion process.

Published: July 2024

AbstractMarine biofouling, which is one of the technical challenges hindering the growth of the marine economy, has been controlled using cuprous oxide (Cu2O) nanoparticles due to the exceptional antifouling properties of Cu(I) ions. However, Cu2O nanoparticles have encountered bottlenecks due to explosive releases of Cu+ ions, high toxicity at elevated doses, and long‐term instability. Here, we present a novel method called Redox Concomitant Formation (RCF) for fabricating a hierarchical Cu(I) metal–organic framework polypyrrole (Cu(I)−MOF/PPy) composite. This method enables in situ phase transition via successive redox reactions that change the chemical valence state and coordination mode of Cu(II)−MOF, resulting in a new structure of Cu(I)−MOF while creating a PPy layer surrounded by the hierarchical structure. Owing to the steady release of Cu+ ions from the Cu(I) sites and photothermal properties of PPy, Cu(I)−MOF/PPy exhibits superior and broad‐spectrum resistance to marine bacteria, algae, and surface‐adhered biofilms in complex biological environments, as well as long‐term stability, resulting in 100 % eradication efficiency under solar‐driven heating. Mechanistic insights into successive structural redox reactions and formation using the RCF method are provided in detail, enabling the fabrication of novel MOFs with the desired composition and structure for a wide range of potential applications.

Published: July 2024

AbstractCisplatin (CDDP) is an FDA‐approved chemotherapeutic drug used for treating various solid tumors. Despite of its effectiveness towards chemotherapy, it faces several challenges, such as multi‐drug resistance (MDR) and significant damage to the normal tissues. To address these challenges, various nanoformulations were developed to improve the delivery and safety of CDDP. One of the limitation in these CDDP loaded nanoformulations is that the effective CDDP loading concentrations are very poor. Therefore, this leaves a grand challenge to develop an effective strategy to carry higher concentrations of CDDP molecules, and also simultaneously exhibit very unique properties. Herein, we have developed an one‐pot synthesis of Cisplatin encapsulated Plasmonic blackbody (CiP), which offers a double play for near infrared (NIR) light activatable chemo‐photothermal therapy in destructing cancer cells as well as mediate catalytic reduction of 4‐nitrophenol (4‐NP). The CiP nanoformulation exhibits superior light absorbing capabilities in the NIR region with an appreciable photothermal conversion efficiency of 41 %. Further, NIR light activatable combinatorial therapeutic approach of CiP was demonstrated against ovarian cancer cells and as a catalyst for the reduction of model pollutant 4‐nitrophenol. Our findings highlight the potential of CiP as a versatile platform for light‐activated combinatorial cancer therapy and environmental pollutant remediation.

Published: July 2024

AbstractIn this study, an environmentally sustainable fluorimetric method for determination of Vonoprazan fumarate (VON) in dosage forms using nanoprobes consisting of nitrogen and sulfur co‐doped carbon quantum dots (N, S‐CQDs). The N, S‐CQDs were prepared through a microwave‐assisted method in 30 s. The resulting N, S‐CQDs were characterized using transmission electron microscopy (TEM), high‐resolution transmission electron microscopy (HRTEM), Fourier transform infrared spectroscopy (FTIR), and X‐ray photoelectron spectroscopy (XPS). They exhibit fluorescence emission at 460 nm after excitation at 385 nm with a high quantum yield (60%). The analytical approach for VON determination relies on the quenching effect exerted by VON on the native fluorescence intensity of CQDs. The quenching mechanism was investigated using Stern–Volmer plots. The proposed method demonstrates linearity across a concentration range 10–80 μM (4.6–36.8 μg/mL) with corresponding limits of detection and quantitation calculated as 2.17 μM (0.99 μg/mL) and 6.58 μM (3.02 μg/mL), respectively. The method has been effectively utilized for the determination of VON in the pharmaceutical samples. Statistical comparison with reported RP‐HPLC has been performed to verify the accuracy and precision of the developed method. The environmental sustainability of the developed method has been thoroughly examined through various greenness metrics.

ABSTRACTBackgroundThe aim of this case study is to present the rationality and scientific evidence of a new design for a double (DA) and triple (TA) dental abutment‐implant with their specific new concept of biodynamic optimized peri‐implant tissue (BOPiT).MethodsThe innovative design of these abutments with a paraboloid geometry was based on BOPiT, simultaneously involving the principles of mechanobiology, biotensegrity, and mechanotransduction. Thus, 37 consecutive individuals/43 cases rehabilitated with single dental implant using the innovative DA (n = 28) and TA (n = 15) on 43 implants were included in this case study. The DA and TA support 2 or 3 dental crowns on a single implant, respectively. Clinic and radiographic examinations were presented at T1 (loading after 4 months) and T2 [final examination with an average follow‐up time of 7.2 years (>3 to 12 years)].ResultsAt T2, mean scores for plaque index, peri‐implant bleeding on probing, and peri‐implant probing depth were low, depicting healthy peri‐implant conditions. All radiographic images showed insignificant annual marginal bone loss (0.022 ± 0.05 mm) when compared to T1, reflecting great bone stability.ConclusionDA and TA, based on the BOPiT concept, represent an advantageous, simple and non‐invasive mechanism for the longevity and healthy regulation of the peri‐implant tissues.
