Published: October 2023

AbstractThe coordination microenvironment modulation of single‐atom catalysts (SACs) based on p‐block metals holds promise for excavating their enormous potential in electrochemical CO2‐to CO conversion. Guided by the instructive theoretical calculations over serial asymmetric coordination microenvironments, herein, a novel Pb SAC with highly asymmetric coordination microenvironment (Pb‐N2SV) is developed. Namely, the Pb atom is coordinated with two N atoms, one S atom and one vacancy nearby. With the breaking of coordination symmetry, the obtained Pb‐N2SV shows excellent ECR performance with 97.3% Faradaic efficiency of CO at −0.47 V, and long‐term stability of 33 h, which exceeds the vast majority of main‐group SACs. More importantly, in situ spectroscopy and density functional theory (DFT) studies unveil that the S doping in Pb SAC can significantly improve electron localization around Pb sites to facilitate *COOH intermediate adsorption, while the introduction of vacancy defect nearby the Pb sites can function as a synergistic modulation on the electronic structure for favorable *CO intermediate desorption, which jointly contributes to achieve the suitable adsorption energy for reaction intermediates to boost the ECR process. As an expandability, this approach will be widely used to construct SACs with unique coordination microenvironment for other challenging catalysis.

AbstractRechargeable aqueous zinc‐ion batteries (ZIBs) are threatened by the cathode dissolution and anode corrosion/dendrites, resulting in poor reversibility. Here, a multifunctional electrolyte is developed to regulate the cathode, anode interface, and solvation by introducing a low‐cost diethylene glycol monomethyl ether (DGME). The DGME can modulate the primary solvation sheath (PSS) of the hydrated Zn2+ and destroy the original hydrogen bond network of water, while the electric double layer (EDL) interface is reconstructed by the adsorption of DGME, which guides the uniform deposition of Zn2+ on the (002) crystal plane. Simultaneously, the DGME also effectively inhibits the dissolution of VO2 and enhances the reaction kinetics. As a proof of concept, the Zn//Cu cells deliver 2000 cycles with an ultrahigh coulombic efficiency (CE) of 99.6%. Additionally, the multifunctional electrolyte significantly improves the multiple performance of Zn//VO2 full cells. The low‐cost and multifunctional electrolyte can be readily applied to ZIBs, demonstrating its practical versatility.

AbstractThe emerging wide varieties of the van der Waals (vdW) magnets with atomically thin and smooth interfaces hold great promise for next‐generation spintronic devices. However, due to the lower Curie temperature of the vdW ferromagnets than room temperature, electrically manipulating its magnetization at room temperature has not been realized. In this work, it is demonstrated that the perpendicular magnetization of the vdW ferromagnet Fe3GaTe2 can be effectively switched at room temperature in the Fe3GaTe2/Pt bilayer by spin–orbit torques (SOTs) with a relatively low current density of 1.3 × 107A cm−2. Moreover, the high SOT efficiency of ξDL ≈ 0.28 is quantitatively determined by harmonic measurements, which is higher than those in Pt‐based heavy metal/conventional ferromagnet devices. The findings of room‐temperature vdW ferromagnet switching by SOTs provide a significant basis for the development of vdW‐ferromagnet‐based spintronic applications.

AbstractSelf‐assembling peptides are valuable building blocks to fabricate supramolecular biomaterials, which have broad applications from biomedicine to biotechnology. However, limited choices to induce different globular proteins into hydrogels hinder these designs. Here, an easy‐to‐implement and tunable self‐assembling strategy, which employs Ure2 amyloidogenic peptide, are described to induce any target proteins to assemble into supramolecular hydrogels alone or in combination with notable compositional control. Furthermore, the collective effect of nanoscale interactions among amyloid nanofibrils and partially disordered elastomeric polypeptides are investigated. This led to many useful macroscopic material properties simultaneously emerging from one pure protein material, i.e. strong adhesion to any substrates under wet conditions, rapidly self‐‐assembling into robust and porous hydrogels, adaptation to remodeling processes, strongly promoting cell adhesion, proliferation and differentiation. Moreover, he demonstrated this supramolecular material′s robust performance in vitro and vivo for tissue engineering, cosmetic and hemostasis applications and exhibited superior performance compared to corresponding commercial counterparts. To the best of his knowledge, few pure protein‐based materials could meet such seemingly mutually exclusive properties simultaneously. Such versatility renders this novel supramolecular nanomaterial as next‐generation functional protein‐based materials, and he demonstrated the sequence level modulation of structural order and disorder as an untapped principle to design new proteins.

AbstractGas reactant transport plays a crucial role in various gas‐consumption reaction‐based electrochemical devices, but the pivotal performance limitation still centers on gas diffusion electrodes (GDEs). To this end, natural cross‐cut wood to prepare GDEs for aluminum–air batteries is introduced by utilizing the ordered structure with microchannels. With cobalt–nitrogen co‐doped carbon nanotubes as the oxygen reduction reaction catalysts grown inside the channels of carbonized wood slice and wettability gradient modification, cherry‐based GDE achieves higher power density (267 vs. 236 mW cm−2) than the commercial carbon fiber paper‐based electrode. By bridging the identified characteristics of pore structure via deep‐learning image recognition technology with the permeability of other three typical kinds of (ash, pine, and oak) wood‐based GDEs, it is revealed that the ratio of effective porosity to the average pore size is key to the performance. This work demonstrates the feasibility of bio‐derived wood‐based materials for fabricating high‐performance GDEs and provides insights into pore structure for the rational design of structured electrodes.
On the Origin of Energetic Disorder in Mixed Halides Lead Perovskites

Published: October 2023

AbstractMixed halide perovskites are emerging as promising candidates for wide‐bandgap components in tandem solar cells and color‐tunable light‐emitting diodes. Yet, halide mixing poses a fundamental question of whether the inhomogeneous halide distribution impacts the intrinsic electronic disorder in these materials. To address this point, density functional theory (DFT)‐based molecular dynamics (MD) simulations are performed for pure and mixed halide perovskites, accounting for disorder stemming from inhomogeneous chemical composition associated with the halide component and from finite temperature effects. For pure halide perovskites, finite‐temperature band gap fluctuations from the MD simulations are in good agreement with the broadening measured using photoluminescence. Furthermore, these calculations confirm the natively modest inhomogeneous disorder in the electronic structure of these materials. Most notably, such a low degree of electronic disorder is preserved in models mimicking finely intermixed Br/I solid‐state solutions. In contrast, models featuring halide segregation show comparably wider band gap fluctuations, with a sizable contribution from inhomogeneous (static) broadening, which is associated, at least in part, with structural distortions stemming from lattice mismatch.

AbstractIt is well known that triplet–triplet annihilation upconversion (TTU) can enhance electroluminescence (EL) efficiency by converting two low‐energy triplet excitons into one high‐energy singlet exciton. However, conventional intermolecular TTU requires high doping concentration to activate, limiting device architecture. Here, six dimer molecules comprised of two anthracene units connected by a spacer unit are investigated, which have a possibility of the intramolecular TTU process. As a result, two dimer molecules show high TTU efficiencies close to the theoretical maximum even in dispersed, diluted conditions. By comparing these molecular conformations, a correlation is found between the dimer structures of two anthracene units and the TTU activity in the diluted condition, i.e., the 3D molecular structure with the exciton utilizing efficiency.

AbstractThe success of arsenic in degrading PML‐RARα oncoprotein illustrates the great anti‐leukemia value of inorganics. Inspired by this, the therapeutic effect of inorganic selenium on t(8; 21) leukemia is studied, which has shown promising anti‐cancer effects on solid tumors. A leukemia‐targeting selenium nanomedicine is rationally built with bioengineered protein nanocage and is demonstrated to be an effective epigenetic drug for inducing the differentiation of t(8;21) leukemia. The selenium drug significantly induces the differentiation of t(8;21) leukemia cells into more mature myeloid cells. Mechanistic analysis shows that the selenium is metabolized into bioactive forms in cells, which drives the degradation of the AML1‐ETO oncoprotein by inhibiting histone deacetylases activity, resulting in the regulation of AML1‐ETO target genes. The regulation results in a significant increase in the expression levels of myeloid differentiation transcription factors PU.1 and C/EBPα, and a significant decrease in the expression level of C‐KIT protein, a member of the type III receptor tyrosine kinase family. This study demonstrates that this protein‐nanocaged selenium is a potential therapeutic drug against t(8;21) leukemia through epigenetic regulation.

Published: October 2023

AbstractDeubiquitylating enzymes (DUBs) maintain relative homeostasis of the cellular ubiquitome by removing the post‐translational modification ubiquitin moiety from substrates. Numerous DUBs have been demonstrated specificity for cleaving a certain type of ubiquitin linkage or positions within ubiquitin chains. Moreover, several DUBs perform functions through specific protein–protein interactions in a catalytically independent manner, which further expands the versatility and complexity of DUBs’ functions. Dysregulation of DUBs disrupts the dynamic equilibrium of ubiquitome and causes various diseases, especially cancer and immune disorders. This review summarizes the Janus‐faced roles of DUBs in cancer including proteasomal degradation, DNA repair, apoptosis, and tumor metastasis, as well as in immunity involving innate immune receptor signaling and inflammatory and autoimmune disorders. The prospects and challenges for the clinical development of DUB inhibitors are further discussed. The review provides a comprehensive understanding of the multi‐faced roles of DUBs in cancer and immunity.

Published: October 2023

AbstractAcoustically‐driven bubbles at the micron scale can generate strong microstreaming flows in its surrounding fluidic medium. The tunable acoustic streaming strength of oscillating microbubbles and the diversity of the generated flow patterns enable the design of fast‐moving microrobots with multimodal locomotion suitable for biomedical applications. The acoustic microrobots holding two coupled microbubbles inside a rigid body are presented; trapped bubbles inside the L‐shaped structure with different orifices generate various streaming flows, thus allowing multiple degrees of freedom in locomotion. The streaming pattern and mean streaming speed depend on the intensity and frequency of the acoustic wave, which can trigger four dominant locomotion modes in the microrobot, denoted as translational and rotational, spinning, rotational, and translational modes. Next, the effect of various geometrical and actuation parameters on the control and navigation of the microrobot is investigated. Furthermore, the surface‐slipping multimodal locomotion, flow mixing, particle manipulation capabilities, the effective interaction of high flow rates with cells, and subsequent cancerous cell lysing abilities of the proposed microrobot are demonstrated. Overall, these results introduce a design toolbox for the next generation of acoustic microrobots with higher degrees of freedom with multimodal locomotion in biomedical applications.

Published: October 2023

AbstractMiniature robots have been widely studied and applied in the fields of search and rescue, reconnaissance, micromanipulation, and even the interior of the human body benefiting from their highlight features of small size, light weight, and agile movement. With the development of new smart materials, many functional actuating elements have been proposed to construct miniature robots. Compared with other actuating elements, piezoelectric actuating elements have the advantages of compact structure, high power density, fast response, high resolution, and no electromagnetic interference, which make them greatly suitable for actuating miniature robots, and capture the attentions and favor of numerous scholars. In this paper, a comprehensive review of recent developments in miniature piezoelectric robots (MPRs) is provided. The MPRs are classified and summarized in detail from three aspects of operating environment, structure of piezoelectric actuating element, and working principle. In addition, new manufacturing methods and piezoelectric materials in MPRs, as well as the application situations, are sorted out and outlined. Finally, the challenges and future trends of MPRs are evaluated and discussed. It is hoped that this review will be of great assistance for determining appropriate designs and guiding future developments of MPRs, and provide a destination board to the researchers interested in MPRs.

Published: October 2023

AbstractIt is of great significance to develop high‐performance n‐type ionic thermoelectric materials. Herein, the turnover from p‐ to n‐type and great improvement in the n‐type ionic Seebeck coefficient of ionogels through synergistic dopings of cations and anions, is reported. Doping with silver trifluoromethanesulfonate (AgOTf) can turn the ionic Seebeck coefficient of the ionogels consisting of poly(vinylidene fluoride‐co‐hexafluoropropylene) (PVDF‐HFP) and 1‐butyl‐3‐methylimidazolium tetrafluoroborate (BMIM:BF4) from 5.52 to −26.4 mV K−1 under a relative humidity (RH) of 75%. The TE performances can be further improved through the combination with the anti‐solvent method, and the ZTi value can be up to 1.7 under 91% RH, the highest for n‐type ionogels. Such p‐ to n‐type turnover and great improvement in the n‐type ionic Seebeck coefficient can be attributed to synergistic doping by Ag+ and OTf−. Ag+ can form a complex with BMIM+, and OTf− can have strong Coulomb interaction to BMIM+. Both can retard the migration of the BMIM+ cations and thus increase the difference in the mobilities of BMIM+ and BF4−. This is the first time that synergistic dopings by both cations and anions for ionic TE materials has been observed.

Published: October 2023

AbstractInterpersonal violence (IV) is a serious concern for adolescents in the United States that has devastating impacts for individuals and communities. Given the increased importance placed on friendships during adolescence, the purpose of the current study was to examine the extent to which IV experiences cluster within youths' friendship networks. Participants were students (N = 1303) in grades 7th to 10th who completed surveys at the beginning and end of an academic year. Results showed that friends' average perpetration (i.e., the percentage of the friends they nominated who perpetrated IV) was strongly associated with likelihood of individual perpetration at baseline but not at the follow‐up. For victimization, friends' average report of victimization (i.e., the percentage of the friends they nominated who were victimized) was associated with higher likelihood reporting of victimization (at both baseline and follow‐up). Although future research is needed to understand explanatory mechanisms underlying these findings, it is possible that the effectiveness of prevention initiatives may be enhanced by incorporating peer group information.
The now and future of human biology at the extremes: An introduction to the special issue
Authors: Niclou Alexandra , Sarma Mallika S. 
Published: October 2023

AbstractObjectivesA hallmark of the human species is our adaptability to a wide range of different ecologies and ecosystems, including some of the most extreme settings. Human biologists have long studied how humans have successfully (and sometimes unsuccessfully) adapted to such extremes, particularly ecological extremes like environments at lower limits of temperature and high altitude. In this special issue, we revisit traditional definitions and explore new conceptions of work in extreme environments. We argue that our definitions of extremes should change with our changing world, and account for extremes unique to the Anthropocene, including environments of inequality and precarity, pandemic landscapes, climate‐impacted settings, obesogenic environments, and the environments of human spaceflight. We also explore the future of work at the extremes and provide some suggested guidelines on how human biologists can continue to build and expand on foundational work in this area.ConclusionWhile human biologists have done critical work on groups living in extreme environments, our definitions of humans at the limits continue to change as the world around us also changes. Scholars in this area have a responsibility to re‐examine the parameters of extremes to stay at the forefront of scientific exploration and collaboration so human biology, as a discipline, can continue to shape our understanding of adaptability, and thus contribute to the continued thriving of all humans as we endure new climatic, environmental, and societal extremes.

Published: October 2023

AbstractWith increasing ecological and environmental concerns, tin (Sn)‐based perovskite light‐emitting diodes (PeLEDs) are competitive candidates for future displays because of their environmental friendliness, excellent photoelectric properties, and low‐cost solution‐processed fabrication. Nonetheless, their electroluminescence (EL) performance still lags behind that of lead (Pb)‐based PeLEDs due to the fast crystallization rate of Sn‐based perovskite films and undesired oxidation from Sn2+ to Sn4+, leading to poor film morphology and coverage, as well as high density defects. Here, we propose a ligand engineering strategy to construct high‐quality phenethylammonium tin iodide (PEA2SnI4) perovskite films by using L‐glutathione reduced (GSH) as surface ligands toward efficient pure red PEA2SnI4‐based PeLEDs. We show that the hydrogen‐bond and coordinate interactions between GSH and PEA2SnI4 effectively reduce the crystallization rate of the perovskites and suppress the oxidation of Sn2+ and formation of defects. The improved pure red perovskite films not only show excellent uniformity, density, and coverage but also exhibit enhanced optical properties and stability. Finally, state‐of‐the‐art pure red PeLEDs achieve a record external quantum efficiency of 9.32 % in the field of PEA2SnI4‐based devices. This work demonstrates that ligand engineering represents a feasible route to enhance the EL performance of Sn‐based PeLEDs.

AbstractCovalent organic frameworks (COFs) display great potential to be assembled into proton conductive membranes for their uniform and controllable pore structure, yet constructing self‐standing COF membrane with high crystallinity to fully exploit their ordered crystalline channels for efficient ionic conduction remains a great challenge. Here, a macromolecular‐mediated crystallization strategy is designed to manipulate the crystallization of self‐standing COF membrane, where the −SO3H groups in introduced sulfonated macromolecule chains function as the sites to interact with the precursors of COF and thus offer long‐range ordered template for membrane crystallization. The optimized self‐standing COF membrane composed of highly‐ordered nanopores exhibits high proton conductivity (75 mS cm−1 at 100 % relative humidity and 20 °C) and excellent flow battery performance, outperforming Nafion 212 and reported membranes. Meanwhile, the long‐term run of membrane is achieved with the help of the anchoring effect of flexible macromolecule chains. Our work provides inspiration to design self‐standing COF membranes with ordered channels for permselective application.
