AbstractBy virtue of reversible energy dissipation and good ionic conductivity, metal ions have been extensively introduced to construct hydrogels. However, the traditional soaking method to prepare metal ions coordination hydrogels (MI‐HG) faces the challenge of diffusion and combination of metal ions, leading to weak mechanical properties. Inspired by the leather mineral tanning mechanism, a strategy that controls the accessibility of hydrogels by pickling and basifying processes thus significantly improving the strength and toughness of MI‐HG is proposed. To achieve this, polyvinyl alcohol/poly(acrylamide‐co‐acrylic acid) (PVA/PAM‐co‐PAA) hydrogels‐bearing ligands similar to those of leather collagen are fabricated. Zr4+, Cr3+, Al3+, and Fe3+ commonly used for mineral tanning are chosen as the metal source. The results demonstrate that the mechanical properties of the products (MI‐HGTanning) are significantly promoted, especially for Cr3+ and Zr4+. For example, the tensile strength of Zr‐HGTanning and toughness of Cr‐HGTanning reach 7.79 ± 0.41 Mpa and 28.01 ± 3.1 MJ m−3, approximately three and seven times that of their soaking samples. From macro to micro characterization and by theoretical simulation, the mineral tanning mechanism of metal ions first permeating and then effectively combining with carboxylates, thus improving the mechanical performance of MI‐HGTanning is deciphered, the products of which are promised applications in flexible force sensors.

Published: January 2024

AbstractAbdominal and intrauterine adhesions are common postoperative problems that can cause serious complications. Current adhesives are usually double sided and suffer from poor wet adhesion, nondegradability, and monofunctionality, which limits their application in preventing postoperative adhesions. Herein, a bioinspired microstructured Janus bioadhesive, named OD/GM@PG, with a wet adhesive inner layer and an antiadhesive outer layer is prepared by combining electrostatic spun and adhesive materials. By using both capillary suction and a catechol‐based strategy, the wet adhesive strength and interfacial toughness of the Janus bioadhesive reach 98 kPa and 325 J m−2, respectively, which are much higher than those of commercial fibrin glues and cyanoacrylate glues. The electrostatic spun outer layer acts as a physical barrier with antiadhesive and friction‐reducing effects. Additionally, the Janus bioadhesive demonstrates biodegradable, hemostatic, antioxidative, anti‐inflammatory, and prohealing properties. In vivo results show that the asymmetric adhesion effect of the Janus bioadhesive effectively preventing postoperative abdominal and intrauterine adhesions. Notably, tandem mass tags‐labeled quantitative proteomics analysis demonstrate that the expression of inflammatory response‐associated proteins (S100A8, S100A9) is associated with adhesion; the Janus bioadhesive significantly downregulates this expression. Therefore, the OD/GM@PG Janus bioadhesive is a promising candidate for preventing postoperative adhesions.

AbstractIt's a promising way to address the global freshwater crisis and energy shortage through solar‐driven devices with evaporate, degrade, and generate electricity at the same time. Low‐efficient light‐thermal conversions for multi‐usage limit application. This paper presents a low‐cost melamine foam/TiO2/carbon black/bismuth (MF/TiO2/CB/Bi) composite with excellent activity to simultaneously process photothermal water evaporation, pollutant degradation, and thermoelectric output, namely‚ shooting three birds with one stone. Under 1 sunlight light intensity, the water evaporation rate reach 4.235 kg m−2 h−1, and the maximum electric power output of a single module is 0.733 W m−2. Meanwhile, Rhodamine B (RhB) solution with 4.0 × 10−4 mol L−1 can be almost degraded within 60 min. Excellent performance benefits from the enhanced adsorption by chemicals, 3D structure for accepting more incident light, and hydrophilic group reducing evaporation enthalpy. Combined with the simulation and experiment, the relationship between heat distribution and thicknesses is studied. When less than 1.98 cm, the lateral temperature is higher than the ambient temperature, thus additional energy cannot be obtained. This work provides a facile and novel method for the construction of photothermal conversion materials with multi‐functional, as a new and useful attempt to solve the shortage of fresh water and electric energy, as well as environmental pollution.

AbstractPhotomultiplication type organic photodetectors (PM‐OPDs) exhibit obvious superiority in weak light detection due to their low dark current density (JD) and large photo‐induced current density (JPI). The JD is one of the important parameters that influences light detection sensitivity of PM‐OPDs, how to effectively suppress the JD is a great challenge to improve the performance of PM‐OPDs. In this work, the JD of PM‐OPDs can be suppressed by employing PTAA or doped‐PTAA as the interfacial layer replacing PEDOT:PSS layer. The PM‐OPDs with PTAA layer exhibit a low JD of 2.3 × 10−7 A cm−2 under −6 V bias, which is much smaller than 1.4 × 10−6 A cm−2 for PM‐OPDs with PEDOT:PSS layer. The small molecule DRCN5T is incorporated into PTAA to further passivate surficial defects of PTAA films, which is conducive to reducing the leakage current of PM‐OPDs. The optimal PM‐OPDs exhibit rather low JD of 8.4 × 10−8 A cm−2 under −6 V bias, as well as external quantum efficiency (EQE) of 31700% and specific detectivity (D*) of 1.2 × 1013 Jones at 370 nm. The signal‐noise‐ratio of optimal PM‐OPDs arrives to 89600 under −4.5 V bias under white light illumination with intensity of 1.5 mW cm−2.

AbstractThis study presents an innovative, statistically‐guided magnetron sputtering technique for creating nanoarchitectonics of high‐performing, NiFeMoN electrocatalysts for oxygen evolution reaction (OER) in water splitting. Using a central composite face‐centered (CCF) design, 13 experimental conditions are identified that enable precise optimization of synthesis parameters through response surface methodology (RSM), confirmed by analysis of variance (ANOVA). The statistical analysis highlighted a interaction between Mo% and N% in the nanostructured NiFeMoN and found optimizing values at 31.35% Mo and 47.12% N. The NiFeMoN catalyst demonstrated superior performance with a low overpotential of 216 mV at 10 mA cm−2 and remarkable stability over seven days, attributed to the modifications in electronic structure and the creation of new active sites through Mo and N additions. Furthermore, the NiFeMoN coating, when used as a protective layer for a Si photoanode in 1 m KOH, achieved an applied‐bias photon‐to‐current efficiency (ABPE) of 5.2%, maintaining stability for 76 h. These advancements underscore the profound potential of employing statistical design for optimizing synthesis parameters of intricate catalyst materials via magnetron sputtering, paving the way for accelerated advancements in water splitting technologies and also in other energy conversion systems, such as nitrogen reduction and CO2 conversion.

Published: January 2024

AbstractDynamic doping by electrochemical ion intercalation is a promising mechanism for modulating electronic conductivity, allowing for energy‐efficient, brain‐inspired computing hardware. While proton‐based devices have achieved success in terms of speed and efficiency, the volatility and environmental pervasiveness of hydrogen (H) might limit the robustness of devices during fabrication, as well as the long‐term retention of devices after programming. This motivates the search for alternative working ions. In this work, a proof‐of‐concept is demonstrated for electrochemical ionic synapses (EIS) based on intercalation of Mg2+ions. The reported device has a symmetric design, with MgxWO3used as both the gate and channel material. Increasing the Mg fraction,x, in WO3increases the electronic conductance in a continuum over a large range (80 nS − 2 mS). Ex situ characterization of the channel confirms that modulation of channel conductance is due to Mg2+intercalation. Unlike H‐EIS which rapidly loses programmed conductance states over a few seconds when exposed to air, Mg‐EIS can be operated and has good retention in air, with no sign of degradation after 1 h. Mg2+as a working ion with WO3as the channel is a promising material system for EIS with long‐term retention and low energy consumption.

Published: January 2024

AbstractA key challenge to apply aqueous zinc metal batteries (AZMBs) as next‐generation energy storage device is to improve the rechargeability at high current densities, which is needed to circumvent slowly ion diffusion in anode and sluggish charge transfer of Zn2+. Herein, a zincophilic accordion array derived from MOF is developed as zinc host for simultaneously boosted ion diffusion and charge transfer. The designed host is prepared by etching and disproportionation reactions, the abundant zincophilic Sn sites with nano‐size uniform disperse on accordion arrays nanosheets (Sn‐AA). Then a composite Zn anode (Sn‐AA@Zn) is obtained by compacting Sn‐AA host with zinc power (Zn‐P). The Sn‐AA@Zn anode has an ultra‐low activation energy (37.1 kJ mol−1) and nucleation overpotential (10 mV), achieving fast charge transfer of Zinc deposition. In addition, the cycle life of the symmetric cell with Sn‐AA@Zn anode exceeds 13 000 cycles at 50 mA cm−2, which is 32 times than that of the Zn‐P anode. And the full cell with Sn‐AA@Zn anode and MnO2 cathode maintains a capacity of 122 mAh g−1 after 5000 cycles at 5 Ag−1. Hopefully, the 3D anode based on Sn‐AA@Zn accordion array and Zn‐P has significantly improved the rechargeability of AZMB at high current density.

AbstractCsPbI3 perovskite is a promising light absorber in perovskite solar cells (PSCs) due to its suitable bandgap (Eg) and high chemical stability, but the perovskite phase is metastable in ambient atmosphere and prone to defect formation. To enhance phase stability and reduce defects, forming a low dimensional (LD) perovskite on CsPbI3 has proved effective. However, the energy levels for most of low‐conductivity LD perovskites are not very compatible with those of CsPbI3, which will impair charge separation and device performance. Herein, a new 1D perovskite (5‐Azaspiro[4.4]nonan‐5‐ium lead triiodide, ASNPbI3) with compatible energy levels and a large Eg is reported as a capping layer. The p‐type ASNPbI3 forms a p‐n heterojunction with n‐CsPbI3 with a staggered band alignment, considerably enhancing the carrier separation. Besides, by pre‐forming a ASNPbI3 at an intermediate stage, defects are suppressed in perovskite film. Consequently, the CsPbI3 PSCs based on carbon electrode without hole transporter (C‐PSCs) achieves a PCE of 18.34%, which is among the highest‐reported values for inorganic C‐PSCs. Furthermore, the hydrophobic ASNPbI3 capping layer has a high thermal stability that greatly enhances perovskite phase stability. Hence, the CsPbI3 C‐PSCs maintains 68% of its initial PCE after 400 h aging at 85°C in a N2 glovebox.

AbstractLow‐bandgap mixed tin (Sn)‐lead (Pb) perovskite solar cells promise efficiency beyond the pure‐Pb ones. However, the difference in the interaction rate of SnI2 and PbI2 with organic salts causes spatial distribution heterogeneity of Sn2+ and Pb2+ in mixed Sn─Pb perovskite layers. This causes a Sn‐rich surface, which can trigger more severe Sn2+ oxidation and nonradiative recombination. A strategy, of introducing indium ion (In3+) into the perovskite precursor solution to compete with Sn2+ when reacting with organic salts is developed. Therefore, the nucleation and crystallization of perovskite films are well‐controlled, leading to improved film quality with a more balanced Sn/Pb ratio on the film surface. Additionally, In3+ has a lower reduction potential compared to Sn2+ which can generate an extra energy barrier for Sn2+ oxidation. The improved film quality and reduced surface oxidation result in accelerated electron transfer and reduced carrier recombination rate. The modified devices achieve a power conversion efficiency (PCE) of 23.34%, representing one of the highest PCEs in mixed Sn─Pb solar cells made with PCBM.
Hypoxia, NSAIDs, and autism: A biocultural analysis of stressors in gametogenesis
Authors: Burke Stacie 
Published: January 2024

AbstractCultural and generational trends have increasingly favored “anti‐inflammatory” action, innovating a new class of analgesic, non‐steroidal anti‐inflammatory drugs (NSAIDs) in the 20th century. The modern human body has been molded over evolutionary time and while acknowledging inflammation can be pathologically entwined, it also serves an important role in healthy folliculogenesis and ovulation, shaping cues that drive needed vascular change. This review argues that because of anti‐inflammatory action, the cultural invention of NSAIDs represents a particular stressor on female reproductive‐age bodies, interacting with natural, underlying variation and placing limits on healthy growth and development in the follicles, creating potential autism risk through hypoxia and mutagenic or epigenetic effects. Since testes are analogs to ovaries, the biological grounding extends naturally to spermatogenesis. This review suggests the introduction of over‐the‐counter NSAIDs in the 1980s failed to recognize the unique functioning of reproductive‐age bodies, challenging the cyclical inflammation needed for healthy gamete development. NSAIDs are framed as one (notable) stressor in an anti‐inflammatory era focused on taming the risks of inflammation in modern human life.

AbstractNicotinamide adenine dinucleotide (NAD+) is an essential coenzyme with diverse biological functions in DNA synthesis. Nicotinamide phosphoribosyltransferase (NAMPT) is a key rate‐limiting enzyme involved in NAD+ biosynthesis in mammals. We developed the first chemical tool for optical control of NAMPT and NAD+ in biological systems using photoswitchable proteolysis‐targeting chimeras (PS‐PROTACs). An NAMPT activator and dimethylpyrazolazobenzene photoswitch were used to design highly efficient PS‐PROTACs, enabling up‐ and down‐reversible regulation of NAMPT and NAD+ in a light‐dependent manner and reducing the toxicity associated with inhibitor‐based PS‐PROTACs. PS‐PROTAC was activated under 620 nm irradiation, realizing in vivo optical manipulation of antitumor activity, NAMPT, and NAD+.

AbstractDuring multivalent ions insertion processes, intense electrostatic interaction between charge carriers and host makes the high‐performance reversible Al3+ storage remains an elusive target. On account of the strong electrostatic repulsion and poor robustness, Prussian Blue analogues (PBAs) suffer severely from the inevitable and large strain and phase change during reversible Al3+ insertion. Herein, we demonstrate an entropy‐driven strategy to realize ultralong life aqueous Al‐ion batteries (AIBs) based on medium entropy PBAs (ME‐PBAs) host. By multiple redox active centers introduction, the intrinsic poor conductivity can be enhanced simultaneously, resulting in outstanding capabilities of electrochemical Al3+ storage. Meanwhile, the co‐occupation at metal sites in PBA frameworks can also increase the M−N bond intensity, which is beneficial for constraining the phase change during consecutive Al3+ reversible insertion, to realize an extended lifespan over 10,000 cycles. Based on the calculation at different operation states, the fluctuation of ME‐PBA lattice parameters is only 1.2 %. Assembled with MoO3 anodes, the full cells can also deliver outstanding electrochemical properties. The findings highlight that, the entropy regulation strategy could uncover the isochronous constraint on both strain and phase transition for long‐term reversible Al3+ storage, providing a promising design for advanced electrode materials for aqueous multivalent ions batteries.

COen‐[(iMIC)Li]2 reagieren mit LiAlH4 und (Et2O)2BeBr2 durch redoxneutrale Salzmetathesereaktion zu COen‐[(iMIC)AlH2]2 und COen‐[(iMIC)BeBr]2, bei denen die dianionische COen‐Brücke erhalten bleibt. Alle Verbindungen wurden mittels NMR‐Spektroskopie, Massenspektrometrie und Röntgenbeugung charakterisiert. Die stereoelektronischen Eigenschaften von COon‐[iMIC]2 wurden durch experimentelle und theoretische Methoden quantifiziert.

Published: January 2024

AbstractDeveloping reversible‐deactivation radical polymerization (RDRP) methods that could directly control the thiyl radical propagation is highly desirable yet remains challenging in modern polymer chemistry. Here, we reported the first reversible thiyl radical addition‐fragmentation chain transfer (SRAFT) polymerization strategy, which utilizes allyl sulfides as chain transfer agents for reversibly deactivating the propagating thiyl radicals, thus allowing us to directly control a challenging thiyl radical chain polymerization to afford polymers with well‐defined architectures. A linear dependence of molecular weight on conversion, high chain‐end fidelity, and efficient chain extension proved good controllability of the polymerization. In addition, density functional theory calculations provided insight into the reversible deactivation ability of allyl sulfides. The SRAFT strategy developed in this work represents a promising platform for discovering new controlled polymerizations based on thiyl radical chemistry.

AbstractOrganic molecules bearing chiral sulfur stereocenters exert a great impact on asymmetric catalysis and synthesis, chiral drugs, and chiral materials. Compared with acyclic ones, the catalytic asymmetric synthesis of thio‐heterocycles has largely lagged behind due to the lack of efficient synthetic strategies. Here we establish the first modular platform to access chiral thio‐oxazolidinones via Pd‐catalyzed asymmetric [3+2] annulations of vinylethylene carbonates with sulfinylanilines. This protocol is featured by readily available starting materials, and high enantio‐ and diastereoselectivity. In particular, an unusual effect of a non‐chiral supporting ligand on the diastereoselectivity was observed. Possible reaction mechanisms and stereocontrol models were proposed.
