AbstractBatteries and supercapacitors continue to be one of the most researched topics in the class of energy storage devices. The continuous development of battery and supercapacitor cell components has shown promising development throughout the years—from slabs of pure metal to porous and tailored structures of metal‐based active materials. In this direction, metal–organic frameworks (MOFs) serve great advantages in improving the properties and structure of the derived metal‐based active materials. This research provides a novel electrode material, Ni–Co–Se/C@CuO, derived from Ni–Co‐MOF integrated with pre‐oxidized Cu mesh. The superior electrochemical performance of Ni–Co–Se/C@CuO over Ni–Co‐MOF@CuO is evident through its higher specific capacity, lower resistivity, richer redox activity, and more favorable diffusion‐dominated storage mechanism. When assembled as a hybrid supercapacitor (HSC), the hybrid device using rGO and Ni–Co–Se/C@CuO as electrodes exhibits a high energy density of 42 W h kg−1 at a power density of 2 kW kg−1, and maintains its capacity retention even after 20 000 cycles. The improved capacity performance is also evaluated using first‐principle investigations, revealing that the unique and preserved heterostructure of Ni–Co–Se/C@CuO portrays enhanced metallic properties. Such evaluation of novel electrodes with superior properties may benefit next‐generation electrodes for supercapacitor devices.

AbstractDrug‐resistant bacteria and biofilm‐associated infections are prominent problems in the field of antibacterial medicine, seriously affecting human and animal health. Despite the great potential of nanomaterials in the antibacterial field, overcoming the paradox of size and charge, efficient penetration, and retention within biofilms remain a formidable challenge. Here, self‐assembling chimeric peptide nanoassemblies composed of multiple functional fragments are designed for the treatment of drug‐resistant bacteria and biofilm‐associated infections. Notably, the chimeric peptide self‐assembles into nanofibers at pH 7.4 and is transformable into nanoparticles in the acidic biofilm‐infected microenvironment at pH 5.0, and thus achieves a size reduction and charge increase, improving the penetration into the bacterial biofilms and killing drug‐resistant bacteria by a mechanism dominated by membrane cleavage. In vivo mouse and piglet infection models confirm the ability of chimeric peptide nanoassemblies to reduce bacterial load within biofilms. Collectively, this research on pathological‐environment‐driven nanostructural transformations may provide a theoretical basis for designing high‐performance antibacterial nanomaterials and advance the application of peptide‐based nanomaterials in medicine and animal husbandry.

Published: May 2023

AbstractControversy over artwork's authenticity is ongoing despite numerous technologies for copyright protection. Artists should build their own ways to protect the authority, but these are still open to piracy. Here, a platform is proposed for developing anticounterfeiting labels based on physical unclonable functions (PUFs), in an artist‐friendly manner, brushstrokes. Deoxyribonucleic acid (DNA), which is natural, biocompatible, and eco‐friendly, can be applied as a paint that shows entropy‐driven buckling instability of the liquid crystal phase. Brushed and wholly dried DNA exhibits line‐shaped zig‐zag textures with inherent randomness as a source of the PUF, and its primary performance and reliability are systematically examined. This breakthrough enables the utilization of these drawings in a wider range of applications.

AbstractMetal‐free carbon‐based catalysts have attracted significant attention owing to their unique electronic structure and excellent catalytic activity for the oxygen reduction reaction (ORR). Recently, several heteroatom‐doped carbon catalysts with ORR performances comparable with those of state‐of‐the‐art Pt‐based catalysts have been reported. However, the intrinsic influence of heteroatoms on the catalytic activity has not been thoroughly investigated to date. This paper reports porous carbons co‐doped with N and S, prepared using an ion‐exchange resin and tetramethylammonium cations, with an onset potential of 0.93 V versus reversible hydrogen electrode (RHE) and a half‐wave potential of 0.79 V versus RHE. First‐principles calculations reveal that the change in the atomic charge caused by the co‐doping of N and S is important for inducing a high ORR activity. This paper presents a rational synthetic strategy for metal‐free catalysts and provides fundamental insights into their electrocatalysis.

Published: May 2023

AbstractDouble‐sided microfabrication process on an ultra‐thin silicon film has rarely been attempted due to the challenges in terms of the preparation and handling of a thin film in spite of its promising fabrication potentials. Such a process allows for doubling the thin film device density or providing dual functionalities for a thin film depending on whether the front and back sides of a thin film are processed identically or distinctively. Here, a novel double‐sided thin film processing strategy is introduced by realizing a dual coil patterned ultra‐thin silicon film that is working as an actuating or energy harvesting system. Experimentally, a dual coil patterned thin film enabled using the introduced approach shows remarkably enhanced device performance when compared with a single coil patterned counterpart. Furthermore, a multiphysics simulation model is developed and the resultant modeling data validate the experimentally measured performance enhancement. Finally, the structural durability of the thin film upon cyclic loading is tested and its diverse vibration modes are investigated.

AbstractThe important but remained issue to be addressed to achieve the mass production of perovskite solar modules include a large‐area fabrication of high‐quality perovskite film with eco‐friendly, viable production methods. Although several efforts are made to achieve large‐area fabrication of perovskite, the development of eco‐friendly solvent system, which is precisely designed to be fit to scale‐up methods are still challenging. Herein, this work develops the eco‐friendly solvent/co‐solvent system to produce a high‐quality perovskite layer with a bathing in eco‐friendly antisolvent. The new co‐solvent/additive, methylsulfonylmethane (MSM), efficiently improves the overall solubility and has a suitable binding strength to the perovskite precursor, resulting in a high‐quality perovskite film with antisolvent bathing method in large area. The resultant perovskite solar cells showed high power conversion efficiency of over 24% (in reverse scan), with a good long‐term stability under continuous light illumination or damp‐heat condition. MSM is also beneficial to produce a perovskite layer at low‐temperature or high‐humidity. MSM‐based solvent system is finally applied to large‐area, resulting in highly efficiency perovskite solar modules with PCE of 19.9% (by aperture) or 21.2% (by active area) in reverse scan. These findings contribute to step forward to a mass production of perovskite solar modules with eco‐friendly way.

AbstractIn‐plane microbatteries (MBs) with features of facile integration, mass customization, and especially superior electrochemical performance are urgently required for self‐powered microelectronic devices. In this work, a facile manufacturing process is employed to fabricate Zn–MnO2 MB with a 3D macroporous microelectrode. Benefiting from the high electron/ion transport path of 3D macroporous microelectrode and high mass‐loading of poly(3,4‐ethylenedioxythiophene)‐manganese dioxide (PEDOT‐MnO2) film, the MB achieves an ultrahigh capacity of 0.78 mAh cm−2 and an outstanding areal energy density of 1.02 mWh cm−2. Moreover, 3D macroporous PEDOT‐MnO2 hybrid film is achieved by one‐step electrodeposition, which effectively improves the cycling performance without reducing areal capacity or hindering the ion diffusion. Notably, the MB can stably drive an electronic timer for ≈400 min or be integrated and operated on the surface of a digital hygro‐thermometer. The MBs are capable of operating stably in the high rotation speed and vibration condition, such as applied on the surface of an axial‐flow fan. Moreover, the MB can integrate by stacking the substrate‐free microelectrodes and achieving outstanding energy density of 3.87 mWh cm−2. Therefore, the PEDOT‐MnO2//Zn MB has good prospects as a next‐generation component applied in self‐powered microelectronic devices.

AbstractZellweger spectrum disorder (ZSD) is a group of autosomal recessive disorders caused by biallelic pathogenic variants in any one of the 13 PEX genes essential for peroxisomal biogenesis. We report a cohort of nine infants who presented at birth with severe neonatal features suggestive of ZSD and found to be homozygous for a variant in PEX6 (NM_000287.4:c.1409G > C[p.Gly470Ala]). All were of Mixtec ancestry and identified by the California Newborn Screening (NBS) Program to have elevated C26:0‐lysophosphatidylcholine but no reportable variants in ABCD1. The clinical and biochemical features of this cohort are described within. Gly470Ala may represent a founder variant in the Mixtec population of Central California. ZSD should be considered in patients who present at birth with severe hypotonia and enlarged fontanelles, especially in the setting of an abnormal NBS, Mixtec ancestry, or family history of infant death. There is a need to further characterize the natural history of ZSD, the Gly470Ala variant, and expand upon possible genotype–phenotype correlations.

Published: May 2023

AbstractHerein we reported the first enantioselective acetoxycarbonylation of internal (Z)‐alkenes, featuring with a sterically hindered Quinox ligand. The desired acetoxyester products, which could be easily transformed into various biologically important molecules, were obtained in moderate to good yields and excellent enantioselectivities, along with good functional groups compatibility. Further transformations of these acetoxyesters into natural product analogous demonstrated the synthetic utility and application of this method.

Published: May 2023

AbstractThe construction of nanotubular structures with non‐deformable inner pores is of both fundamental and practical significance. Herein we report a strategy for creating molecular nanotubes with defined lengths. Macrocyclic (MC) units based on shape‐persistent hexakis(m‐phenylene ethynylene) (m‐PE) macrocycle MC‐1, which are known to stack into hydrogen‐bonded tubular assemblies, are tethered by oligo(β‐alanine) linkers to give tubular stacks MC‐2 and MC‐4 that have two and four MC units, respectively. The covalently linked MC units in MC‐2 and MC‐4 undergo face‐to‐face stacking through intramolecular non‐covalent interactions that further results in the helical stacks of these compounds. Oligomer MC‐4 can form potassium and proton channels across lipid bilayers, with the channels being open continuously for over 60 seconds, which is among the longest open durations for synthetic ion channels and indicates that the thermodynamic stability of the self‐assembling channels can be drastically enhanced by reducing the number of molecular components involved. This study demonstrates that covalently tethering shape‐persistent macrocyclic units is a feasible and reliable approach for building molecular nanotubes that otherwise are difficult to create de novo. The extraordinarily long lifetimes of the ion channels formed by MC‐2 and MC‐4 suggest the likelihood of constructing the next‐generation synthetic ion channels with unprecedented stability.
Geometric Isomerisation of Bifunctional Alkenyl Fluoride Linchpins: Stereodivergence in Amide and Polyene Bioisostere Synthesis

Published: May 2023

AbstractAmide groups are pervasive across the chemical space continuum, where their structural and pharmacological importance, juxtaposed with the hydrolytic vulnerabilities, continues to fuel bioisostere development. Alkenyl fluorides have a venerable history as effective mimics (Ψ[CF=CH]) owing to the planarity of the motif and intrinsic polarity of the C(sp2)−F bond. However, emulating the s‐cis to the s‐trans isomerisation of a peptide bond with fluoro‐alkene surrogates remains challenging, and current synthetic solutions only enable access to a single configuration. Through the design of an ambiphilic linchpin based on a fluorinated β‐borylacrylate, it has been possible to leverage energy transfer catalysis to affect this unprecedented isomerisation process: this provides geometrically‐programmable building blocks that can be functionalised at either terminus. Irradiation at λmax=402 nm with inexpensive thioxanthone as a photocatalyst enables rapid, effective isomerisation of tri‐ and tetra‐substituted species (up to E/Z 98 : 2 in 1 h), providing a stereodivergent platform for small molecule amide and polyene isostere discovery. Application of the methodology in target synthesis and initial laser spectroscopic studies are disclosed together with crystallographic analyses of representative products.

AbstractSelf‐sorting is commonly observed in complex reaction systems, which has been utilized to guide the formation of single major by‐design molecules. However, most studies have been focused on non‐covalent systems, and using self‐sorting to achieve covalently bonded architectures is still relatively less explored. Herein, we first demonstrated the dynamic nature of spiroborate linkage and systematically studied the self‐sorting behavior observed in the transformation between spiroborate‐linked well‐defined polymeric and molecular architectures, which is enabled by spiroborate bond exchange. The scrambling between a macrocycle and a 1D helical covalent polymer led to the formation of a molecular cage, whose structures are all unambiguously elucidated by single‐crystal X‐ray diffraction. The results indicate that the molecular cage is the thermodynamically favored product in this multi‐component reaction system. This work represents the first example of a 1D polymeric architecture transforming into a shape‐persistent molecular cage, driven by dynamic covalent self‐sorting. This study will further guide the design of spiroborate‐based materials and open the possibilities for the development of novel complex yet responsive dynamic covalent molecular or polymeric systems.
Amphiphilic Polymer Hydrogel‐supported Catalysts: Tuning the Accessibility to the Catalytic Site by Molecular Jacketing

Published: May 2023

AbstractCrosslinked amphiphilic hydrogels, prepared using a peripherally clickable hyperbranched polyester (HBP) and PEG‐diazides of different molecular weights, were used to ligate Cu utilizing the triazole rings formed by the alkyne‐azide click reaction. Since only a fraction of the peripheral propargyl groups in the HB polyester are needed to generate the crosslinked polymer, the remaining were clicked with different types of azides, such as MPEG azide, decyl azide or 4‐methylbenzyl azide, to create a molecular jacket around the catalytic sites that can potentially influence the catalytic activity and reaction outcome. The crosslinked films ligated with Cu functioned very effectively to catalyse alkyne‐azide click reactions, both in water and in organic solvents; the nature of the molecular jacket around the catalytic site had a clear influence the reaction rate, which depended upon the relative solubilities of the reactants. The gel‐supported catalyst films were reused multiple times with little loss in catalytic activity.
Multi‐AGV route planning in automated warehouse system based on shortest‐time Q‐learning algorithm
Authors: Zhang Zheng , Chen Juan , Zhao Wenbing 
Published: May 2023

AbstractRoute planning for automated guided vehicles (AGVs) is one of the key factors that affects work efficiency of automated storage and retrieval systems (AS/RSes). Route planning plays an important role in the operation of AGVs. Since the characteristic of AS/RSes is chessboard‐like, the environment is more complex than traditional route planning environments because the number of nodes is large, more than one shortest route exists between two nodes, and the routes with the shortest distance may not be the most energy‐saving routes. Although the traditional route planning algorithms such as the classical Q‐learning algorithm can work well in AGV route planning, it also has some limitations. This paper proposes a novel multi‐AGV route planning approach to solving the AGV route planning problem in the chessboard‐like warehouse, which can improve the route planning efficiency greatly. First, by combining adjacency matrix and reward matrix, we propose a low‐dimensional adjacency‐reward matrix for route planning. This algorithm improves the efficiency of classical Q‐learning algorithms and accelerates dynamic route planning significantly. We further improve the algorithm by considering the travel directions to minimize the number of turns in the route and additionally by considering whether the AGV is loaded or not and plan routes accordingly. Finally, we propose a multi‐AGV online collision‐free route planning algorithm based on these considerations for dynamic route planning for multi‐AGVs operating in a large‐scale warehouse. The proposed algorithms are validated with several case studies.
Brief report: Publications from mainland China, Hong Kong, and Taiwan in behavioral journals 1980–2021

Published: May 2023

AbstractResearch involving international research communities has been advocated in the field of behavior analysis (Dymond et al., 2000; Martin et al., 2016). The purpose of the present study was to report the status of behavioral research in mainland China, Hong Kong, and Taiwan, in terms of number of publications, types of research, and frequency of collaboration with international researchers. Fifteen behavioral journals were selected from the list by Cooper et al. (2020). These were searched by hand to find publications conducted in or authored by researchers from mainland China, Hong Kong, and Taiwan dating from each journal's inception to December 2021. The earliest publication we found appeared in 1980 in The Psychological Record. Over the following four decades (1980–1989; 1990–1999; 2000–2009; 2010–2021), the number of publications per decade increased dramatically and continues in recent years to rise. Publications include research reports, review papers, and conceptual articles, with the majority being basic research reports published in Behavioral Processes. Approximately half the publications involve collaboration with international researchers, mostly in North America. Implications for behavioral research, practice, and policy in mainland China, Hong Kong, and Taiwan are discussed.

Published: May 2023

AbstractPeriodontitis is an infection‐induced inflammation, evidenced by an increase in inflammatory macrophage infiltration. Recent research has highlighted the role of plasma‐activated medium (PAM) as a regulator of the innate immune system, where macrophages are the main effector cells. This study therefore aims to investigate the immunomodulatory effects of PAM on macrophages and its potential applications for periodontitis management. PAM was generated using an argon jet and applied to culture macrophages. Proinflammatory macrophage markers were significantly reduced after PAM stimulation, and this was correlated with the activation of autophagy via the Akt signaling pathway. Further investigations on the proregenerative effects of PAM‐treated macrophages on periodontal ligament cells (PDLCs) revealed a significant increase in the expression of osteogeneis/cementogenesis‐associated markers as well as mineralization nodule formation. Our findings suggest that PAM is an excellent candidate for periodontal therapeutic applications.

AbstractFrom the fruits of Schisandra cauliflora, five new dimethylbutyrylated dibenzocyclooctadiene lignans, named schisandracaurins A−E, were isolated using separation and chromatographic techniques. Their structures were determined by extensive analyses of HR‐ESI‐MS, NMR, and ECD spectra. The schisandracaurins A−E potentially inhibited NO production in LPS‐activated RAW264.7 cells with their IC50 values from 21.4 to 30.3 μM.
