Published: January 2024

AbstractVanadium‐based compounds are explored as promising electrode materials in lithium/sodium‐ion batteries exhibiting superior energy storage properties. However, similar attempts are rarely reported for potassium‐ion batteries (PIBs), in which the fundamental reaction mechanisms remain inexplicit. Herein, porous CaV4O9 nanobelts (NBs) are selected as a PIB anode to systematically investigate potassium storage mechanisms through in situ transmission electron microscopy. In situ measurements track overall electrochemical potassiation reactions of CaV4O9 and identify a polyphase state of V4O7, CaO, and K2O phases after potassiation. Unexpectedly, the potassiated products can be partially converted back to the original CaV4O9 phase with residual VO2 and CaO phases, which is different from the irreversible phase transformations in lithium/sodium storages of CaV4O9. Impressively, the cavities in NBs alternately disappear and appear with (de)potassiation, avoiding the drastic volume change and structural degradation of anodes. The reversible potassium storage and stable cycling are evaluated by electrochemical measurements and in situ X‐ray diffraction analysis. This work provides a paradigm by revisiting the existing anode materials in lithium/sodium‐ion batteries to seek out viable anodes for next‐generation PIBs.

Published: January 2024

AbstractIn a hydrogen fuel cell, an electrolyte membrane conducts protons, but blocks electrons, hydrogen molecules, and oxygen molecules. The fuel cell often runs unsteadily, resulting in fluctuating water production, causing the membrane to swell and contract. The cyclic deformation can cause fatigue crack growth. This paper describes an approach to develop a fatigue‐resistant polymer electrolyte membrane. The membrane is prepared by forming an interpenetrating network of a plastic electrolyte and a rubber. The former conducts protons, and the latter enhances fatigue resistance. The introduction of the rubber modestly reduces electrochemical performance, but significantly increases fatigue threshold and lifespan. Compared to pristine plastic electrolyte, Nafion, an interpenetrating network of Nafion and perfluoropolyether (PFPE) reduces the maximum power density by 20%, but increases the fatigue threshold by 175%. Under the wet/dry accelerated stress test, the fuel cell with the Nafion‐PFPE membrane has a lifespan 1.7 times that of a fuel cell with the Nafion membrane.

AbstractNext‐generation, high‐efficiency energy storage and conversion systems require development of lithium metal batteries. But the high cost of production and constraints on thickness of lithium (anode) foils continue to limit adoption for integration into battery cell architectures. Here, a novel lithium anode manufacturing solution is demonstrated – single‐step production of ultrathin gauge foil formats directly from solid ingot. Hybrid cutting‐based deformation processes, involving large plastic strains and strain rates, produce foil to sub‐10 µm thickness, with surface quality even superior to present Li anode processing routes. Energy analysis shows the single‐stage processing is ≈50% more efficient than conventional processing by extrusion‐rolling. Through in situ force measurements and high‐speed imaging of the cutting it also characterize – for the first time – the flow stress of Li to strain rates of 800 sec−1, revealing a power‐law relationship. The results present a paradigm shift in manufacturing and integration of solid lithium anodes for energy applications.

Published: January 2024

AbstractBright white color is often achieved in nature by the combination of polydisperse scattering structures and high refractive index contrast between the scatterer and the surrounding medium. Similarly, synthetic systems have commonly utilized inorganic materials as the scattering centers to achieve white color, which, however, lacks the ability to switch the optical properties. While hydrogels capable of scattering light are utilized in applications such as smart windows, their reflection properties have remained limited due to the low refractive index contrast between the polymer and water. As a result, thick layers in the millimeter range are often required to achieve reasonable whiteness. Here a hydrogel consisting of a temperature‐responsive poly(N‐isopropylacrylamide) (PNIPAm) and chemically modified agarose used as a chemical macro‐crosslinker is presented. The hydrogel exhibits high whiteness at temperatures above the phase transition (≈31 °C). The reflectance at 800 nm is four times as high as for standard PNIPAm, and a change in transmittance can be induced by laser pulses as short as 30 ms. The macro‐crosslinked structure of this hydrogel provides superior reflectance at a lower thickness compared to reported hydrogel systems, enabling a variety of potential applications including smart windows, responsive displays, optical switches, and camouflage.

Published: January 2024

AbstractThe jammed liquid‐liquid interface offers an elegant approach to achieve non‐equilibrium shapes of liquids. The interfacial jamming subsequently brings about formation of 2D “solid‐like” assembly. In this work, biphasic reaction between a perylenediimide based luminogen benzoperylenediimide monoanhydride (Bp(Im)2MA) and diamines are demonstrated that rendered amide bond formation and in turn amide nanoconjugates across the oil‐water interface. Amide nanoconjugates formed with different diamines showed diamine alkyl chain length dependent varied interfacial properties and sizes. Jamming of the interface is judiciously utilized to induce aggregation of amide nanoconjugates which successfully established macroscopic Aggregation Induced Emission‐switching (AIE‐switching) behavior. Further, the versatility of this approach is extended to analyze the reactivity of chiral amino acids. The reaction between the Bp(Im)2MA luminogen and chiral amino acids exhibits macroscopic enantioselectivity at jammed interface via diverse surface coverage of the amino acids‐based amide nanoconjugates. The formation of discrete nanoscopic amide interfacial assembly for each of the L‐ and D‐ amino acids isomers is corroborated with Atomic Force Microscopy (AFM) images. This study extends a fascinating pathway to aid in understanding and fabrication of structurally diverse jammed interfaces and aggregation of organic molecules across an oil‐water interface.

Published: January 2024

AbstractWe report a vinyl cyanation reaction of vinyl triflates and readily available 1,4‐dicyanobenzene through a nickel‐catalyzed reductive coupling process. The reaction is operated under mild conditions with remarkable functional‐group compatibility. Cyclic vinyl triflates with various ring sizes and substituents at different positions all reacted smoothly. The synthetic utility is demonstrated by the derivatization of pharmaceutical and natural compounds, a scale‐up synthesis, and various functional group transformations. Preliminary mechanistic studies demonstrate that vinyl triflates are more reactive than 1,4‐dicyanobenzene towards the oxidative addition to nickel catalyst.

Published: January 2024

AbstractDespite the attractive properties of tetrafluorosulfanyl (SF4) compounds in drug discovery, medicinal research on SF4 molecules is hindered by the scarcity of suitable synthetic methodologies. Drawing inspiration from the well‐established Sonogashira cross‐coupling of terminal alkynes under Pd‐catalysis, it is envisioned that SF4‐alkynes can serve as effective coupling partners. To overcome the challenges associated with the electron‐deficient nature of SF4‐alkynes and the lability of the SF4 unit under transition‐metal catalysis, an aryl radical mediated Csp–Csp3 cross‐coupling reaction is successfully developed under Cu catalysis. This methodology facilitates the coupling of SF4‐alkynes with alkyl iodides, leading to the immediate synthesis of SF4‐attached drug‐like molecules. These findings highlight the potential impact of SF4‐containing molecules in the drug industry, paving the way for further research in this emerging field.

AbstractLong‐persistent luminescent (LPL) materials have attracted considerable research interest due to their extensive applications and outstanding afterglow performance. However, the performance of red LPL materials lags behind that of green and blue materials. Therefore, it is crucial to explore novel red LPL materials. This study introduces a straightforward and viable strategy for organic–inorganic hybrids, wherein the organic ligand 1,3,6,8‐Tetrakis(4‐carboxyphenyl)pyrene (TCPP) is coordinated to the surface of a red persistent phosphor Sr0.75Ca0.25S:Eu2+ (R) through a one‐step method. TCPP serves as an antenna, facilitating the transfer of absorbed light energy to R via triplet energy transfer (TET). Notably, the initial afterglow intensity and luminance of R increase by twofold and onefold, respectively, and the afterglow duration extends from 9 to 17 min. Furthermore, this study involves the preparation of a highly flexible film by mixing R@TCPP with high‐density polyethylene (HDPE) to create a sound‐controlled afterglow lamp. This innovative approach holds promising application prospects in flexible large‐area luminescence, flexible wearables, and low‐vision lighting.

AbstractTolerance induction is critical for mitigating T cell‐mediated inflammation. Treatments based on anti‐CD3 monoclonal antibody (mAb) play a pivotal role in inducing such tolerance. Anti‐CD3 mAb conjugated with dextran‐coated magnetic nanoparticles (MNPs) may induce inflammatory tolerance is posited. MNPs conjugated with anti‐CD3 mAb (Ab‐MNPs) are characterized using transmission and scanning electron microscopy, and their distribution is assessed using a nanoparticle tracking analyzer. Compared to MNPs, 90% of Ab‐MNPs increased in size from 54.7 ± 0.5 to 71.7 ± 2.7 nm. The in vitro and in vivo studies confirmed the therapeutic material as nontoxic and biocompatible. Mice are administered various dosages of Ab‐MNPs before receiving concanavalin‐A (ConA), an inflammation inducer. Preadministration of Ab‐MNPs, as opposed to MNPs or anti‐CD3 mAb alone, significantly reduced the serum levels of interferon‐γ and interleukin‐6 in ConA‐treated mice. Additionally, the transdermal stamp patch as an effective delivery system for Ab‐MNPs is validated. This study demonstrates the utility of the Ab‐MNP complex in pathologies associated with T cell‐mediated hyperinflammation, such as organ transplantation and COVID‐19.

AbstractTopological insulators have recently received attention in optoelectronic devices because of their high mobility and broadband absorption resulting from their topological surface states. In particular, theoretical and experimental studies have emerged that can improve the spin generation efficiency in a topological insulator‐based p–n junction structure called a TPNJ, drawing attention in optospintronics. Recently, research on implementing the TPNJ structure is conducted; however, studies on the device characteristics of the TPNJ structure are still insufficient. In this study, the TPNJ structure is effectively implemented without intermixing by controlling the annealing temperature, and the photocharacteristics appearing in the TPNJ structure are investigated using a cross‐pattern that can compare the characteristics in a single device. Enhanced photo characteristics are observed for the TPNJ structure. An optical pump Terahertz probe and a physical property measurement system are used to confirm the cause of improved photoresponsivity. Consequently, the photocharacteristics are improved owing to the change in the absorption mechanism and surface transport channel caused by the Fermi level shift in the TPNJ structure.

AbstractAqueous zinc ion batteries (ZIBs) exhibit great potential for next‐generation energy storage devices. However, significant challenges exist, including the uncontrollable formation of Zn dendrite and side reactions during zinc stripping and plating. The mechanism of Zn dendrite nucleation has yet to be fully understood. In this work, the first principles simulations are used to investigate the Zn dendrite formation process. The unintentionally adsorbed O2− and OH− ions are the inducing factors for Zn dendrite nucleation and growth on the Zn (0001) plane due to significantly increased Zn diffusion barriers. A top‐down method is demonstrated to suppress the dendrite using delaminated V2CTx to capture O2− and OH− ions thanks to reduced Zn diffusion barriers. The experimental results revealed significantly suppressed Zn dendrite nucleation and growth, resulting in a layer‐by‐layer deposit/stripping of Zn. Based on the electrochemical evaluations, the V2CTx‐coated Zn composite delivers a high coulombic efficiency of 99.3% at 1.0 mAh cm−2. Furthermore, the full cell achieves excellent cyclic performance of 93.6% capacity retention after 2000 cycles at 1 A g−1. This strategy has broad scalability and can be widely applied in designing metallic anodes for rechargeable batteries.

AbstractWe present a green and efficient approach for synthesizing vicinal diols via a metal‐free photocatalyzed pinacol coupling reaction in water or aqueous media. The mild and practical reaction conditions, including a commercially available organic photocatalyst and a nontoxic solvent, provide wide functional group tolerance while furnishing the corresponding vicinal diols in high yields. Mechanistic studies reveal the crucial role of Hantzsch ester (HEH), which undergoes single‐electron oxidation and subsequently acts as a proton donor to aldehydes for proton‐coupled electron transfer (PCET). This work contributes to the development of environmentally friendly methodologies for carbon−carbon bond formation, aligning with the principles of green and sustainable chemistry.

Published: January 2024

AbstractInspired by the drawstring structure in daily life, here we report the development of a drawstring‐mimetic supramolecular complex at the molecular scale. This complex consists of a rigid figure‐of‐eight macrocyclic host molecule and a flexible linear guest molecule which could interact through three‐point non‐covalent binding to form a highly selective and efficient host‐guest assembly. The complex not only resembles the drawstring structure, but also mimics the properties of a drawstring with regard to deformations under external forces. The supramolecular drawstring can be utilized as an interlocked crosslinker for poly(methyl acrylate), and the corresponding polymer samples exhibit comprehensive enhancement of macroscopic mechanical performance including stiffness, strength, and toughness.

Published: January 2024

AbstractWe present four proton‐responsive palladium and platinum complexes, [MCl2(RPONNHO)] (M=Pd, Pt; R=iPr, tBu) synthesised by complexation of PdCl2 or PtCl2(COD) with the 1,8‐naphthyridine ligand RPONNHO. Deprotonation of [MCl2(tBuPONNHO)] switches ligand coordination from mono‐ to dinucleating, offering a synthetic pathway to bimetallic PdII and PtII complexes [M2Cl2(tBuPONNO)2]. Two‐electron reduction gives planar MI−MI complexes [M2(tBuPONNO)2] (M=Pd, Pt) containing a metal‐metal bond. In contrast to the related nickel system that forms a metallophosphorane [Ni2(tBuPONNOPONNO)], an unusual phosphinite binding mode is observed in [M2(tBuPONNO)2] containing close phosphinite‐naphthyridinone P⋅⋅⋅O interactions, which is investigated spectroscopically, crystallographically and computationally. The presented proton‐responsive and structurally‐responsive RPONNHO and bimetallic RPONNO complexes offer a novel platform for future explorations of metal‐ligand and metal‐metal cooperativity with palladium and platinum.

The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T‐Control® compared with patients with a conventional Foley catheter.Study DesignThis trial is a mixed‐method study comprising a two‐arm, pilot comparative study with random allocation to T‐Control catheter or traditional Foley catheter in patients with long‐term catheterization and a study with qualitative methodology, through discussion groups.EndpointsThe comfort and acceptability of the T‐Control® device (qualitative) and the quality of life related to self‐perceived health (quantitative) will be analysed as primary endpoints. As secondary endpoints, the following will be analysed: magnitude and rate of infections (symptomatic and asymptomatic); days free of infection; indication of associated antibiotic treatments; determination of biofilm; number of catheter‐related adverse events; use of each type of catheterization's healthcare resources; and level of satisfaction and workload of health professionals.Patients and MethodsEligible patients are male and female adults aged ≥18 years, who require a change of long‐term bladder catheter. The estimated sample size is 50 patients. Patient follow‐up includes both the time of catheter insertion and its removal or change 4 weeks later, plus the time until the discussion groups take place.
Isthmin‐1: A critical regulator of branching morphogenesis and metanephric mesenchyme condensation during early kidney development
Authors: Gao Ge , Zhou Zhongjun 
Published: January 2024

AbstractIsthmin‐1 (Ism1) was first described to be syn‐expressed with Fgf8 in Xenopus. However, its biological role has not been elucidated until recent years. Despite of accumulated evidence that Ism1 participates in angiogenesis, tumor invasion, macrophage apoptosis, and glucose metabolism, the cognate receptors for Ism1 remain largely unknown.Ism1deficiency in mice results in renal agenesis (RA) with a transient loss ofGdnftranscription and impaired mesenchyme condensation at E11.5. Ism1 binds to and activates Integrin α8β1 to positively regulate Gdnf/Ret signaling, thus promoting mesenchyme condensation and ureteric epithelium branching morphogenesis. Here, we propose the hypothesis underlying the mechanism by which Ism1 regulates branching morphogenesis during early kidney development.

AbstractBackgroundThe existing literature on the association between brain‐derived neurotrophic factor (BDNF) protein levels and panic disorder presents inconsistent findings. This systematic review and meta‐analysis aim to synthesize the available evidence and determine the overall effect of BDNF protein levels in individuals diagnosed with panic disorder.MethodsA comprehensive literature search was conducted using electronic databases (PubMed, Embase, Scopus, PsycINFO, and Web of Science) from inception to April 21, 2023. The search strategy included relevant keywords and medical subject headings terms related to BDNF, panic disorder, and protein levels. A random‐effects model was used for the meta‐analysis, and subgroup analyses were performed to explore heterogeneity. Publication bias was assessed using funnel plots and statistical tests.ResultsA total of 12 studies met the inclusion criteria. The meta‐analysis demonstrated a significant decrease in BDNF protein levels in individuals with panic disorder (SMD = −.53, 95% CI: −1.02 to −.04, p < .001; I2: 92%). The results of subgroup and meta‐regression analyses were not statistically significant. No significant publication bias was observed based on the results of Egger's regression test (p‐value = .3550).ConclusionThis systematic review and meta‐analysis provide evidence of lower BDNF protein levels in individuals diagnosed with panic disorder compared to healthy controls. The findings suggest a potential role for BDNF dysregulation in the pathophysiology of panic disorder. Further research is warranted to elucidate the underlying mechanisms and potential therapeutic implications.
