Published: July 2023

AbstractFoldable electroluminescent (EL) devices have attracted much attention in recent years. By folding, 2D EL devices can be transformed to 3D structures, which play an important role in foldable, portable, and 3D displays. Foldability is similar to flexibility, but there are differences. Foldable electronic devices mainly focus on the properties of the folding regions, which are flexible or stretchable, while the non‐folding regions may be rigid. On the other hand, folding deformation is usually accompanied by severe and sharp compression and stretching in the folding regions, which have a significant impact on device performance. The unique deformation characteristics make foldable devices complicated in materials, structures, and strategies. In this review, the progress of foldable electronic devices is summarized. According to the crease characteristics, foldable devices are divided into a free‐folding type and a crease‐preset type. First, the materials, structures, and strategies of various non‐luminescent foldable electronic devices are summarized, which will enlighten the research of foldable EL devices. Then, the progress of foldable EL devices is summarized. Foldable EL devices are still in the early stage of research and still face many problems and challenges. It is hoped that this review can promote their rapid development.

Abstract2D materials provide an effective strategy for the construction of fast‐responsive and highly sensitive Schottky heterojunction devices. However, the strong Fermi pinning at the contact between bulk metallic electrodes and 2D semiconductor materials greatly hinders the wide application of such devices in optoelectronics. Herein, a self‐powered photodetector with high performance is fabricated based on an all‐2D van der Waals (vdWs) heterojunction composed of metallic 2H‐NbSe2 and semiconducting MoSe2. Benefiting from the strong built‐in electric field, the device exhibits a high rectification ratio of 2.1 × 103. Furthermore, the photovoltaic effect can be observed in a broad spectrum ranging from 405 to 980 nm without external voltage, where a maximum responsivity of 64.92 A W−1, a maximum specific detectivity of 2.39 × 1014 Jones, and a large on–off current ratio >105 are obtained at 650 nm. Simultaneously, the efficient charge separation at the high‐quality heterointerface of NbSe2/MoSe2 results in a fast response/recovery time of 180/80 µs. This work demonstrates the promising potential of the 2D metallic NbSe2 as an electrode forming a Schottky heterojunction to realize a high‐performance broadband photodetector for near‐infrared communication.

AbstractA practical electrochemical method for synthesizing aryliminophosphoranes from widely available nitro(hetero)arenes in a continuous‐flow system is presented. The utilization of flow technology offers several advantages to our approach, including the elimination of the need for a supporting electrolyte and enhanced scalability. Our method demonstrates good tolerance towards various functional groups, with electron‐deficient nitroarenes being particularly suitable for this strategy. In addition, we have demonstrated the versatility of aryliminophosphoranes as intermediates in synthesizing anilines, amines, and amides. To further enhance the utility of our approach, we have developed a telescoped method that utilizes a tube‐in‐tube setup for the in‐situ production of isocyanates.

Published: July 2023

AbstractHerein, we report the reaction system based on Pd(II) catalyst and Tl(OCOCF3)3 for the electrophilic C3−H alkenylation of 2,6‐dialkokypyridines with alkenes. Synergistic action of the Pd/thioether ligand catalytic system and Tl(III) results in efficient C−H alkenylation of various nitrogen heteroaromatics with complete regioselectivity. Remarkably, the use of a sterically hindered thioether ligand and the Pd(II)/Tl(III) system enables mono‐selective C3(5)−H alkenylation of 2,6‐dialkoxypyridines, and subsequent introduction of a second, different alkene affords unsymmetrical, multi‐substituted pyridine derivatives. Mechanistic studies indicate that the reaction proceeds via electrophilic thallation of heteroarenes followed by Pd‐catalyzed Heck‐type reaction. The utility of this method is showcased by its application to the late‐stage functionalization of structurally complex bioactive molecules having 2,6‐dialkoxypyridine as a core structure.

AbstractThe van der Waals (vdW) ferromagnet Fe3‐δGeTe2 has garnered significant research interest as a platform for skyrmionic spin configurations, that is, skyrmions and skyrmionic bubbles. However, despite extensive efforts, the origin of the Dzyaloshinskii–Moriya interaction (DMI) in Fe3‐δGeTe2 remains elusive, making it challenging to acquire these skyrmionic phases in a controlled manner. In this study, it is demonstrated that the Fe content in Fe3‐δGeTe2 has a profound effect on the crystal structure, DMI, and skyrmionic phase. For the first time, a marked increase in Fe atom displacement with decreasing Fe content is observed, transforming the original centrosymmetric crystal structure into a non‐centrosymmetric symmetry, leading to a considerable DMI. Additionally, by varying the Fe content and sample thickness, a controllable transition between Néel‐type skyrmions and Bloch‐type skyrmionic bubbles is achieved, governed by a delicate interplay between dipole–dipole interaction and the DMI. The findings offer novel insights into the variable skyrmionic phases in Fe3‐δGeTe2 and provide the impetus for developing vdW ferromagnet‐based spintronic devices.

AbstractSelf‐healing ability is crucial to increasing the lifetime and reliability of materials. In this study, spatiotemporal control of the healing of a polysiloxane material is achieved using a cleavable cage compound encapsulating a fluoride ion (F−), which triggeres the dynamic rearrangement of the siloxane (Si–O–Si) networks. A self‐healing siloxane‐based elastomer is prepared by cross‐linking polydimethylsiloxane (PDMS) with a F−‐encapsulating cage‐type germoxane (Ge–O–Ge) compound. This material can self‐heal repeatedly under humid conditions. The F− released by hydrolytic cleavage of the cage framework contributes to rejoining of the cut pieces by promoting the local rearrangement of the siloxane networks. The use of a molecular cage encapsulating a catalyst for dynamic bond rearrangement provides a new concept for designing self‐healing polysiloxane materials based on integrated extrinsic and intrinsic mechanisms.

AbstractHigh‐performance chiroptical synaptic phototransistors are successfully demonstrated using heterojunctions composed of a self‐assembled nanohelix of a π‐conjugated molecule and a metal oxide semiconductor. To impart strong chiroptical activity to the device, a diketopyrrolopyrrole‐based π‐conjugated molecule decorated with chiral glutamic acid is newly synthesized; this molecule is capable of supramolecular self‐assembly through noncovalent intermolecular interactions. In particular, nanohelix formed by intertwinded fibers with strong and stable chiroptical activity in a solid‐film state are obtained through hydrogen‐bonding‐driven, gelation‐assisted self‐assembly. Phototransistors based on interfacial charge transfer at the heterojunction from the chiroptical nanohelix to the metal oxide semiconductor show excellent chiroptical detection with a high photocurrent dissymmetry factor of 1.97 and a high photoresponsivity of 218 A W−1. The chiroptical phototransistor demonstrates photonic synapse‐like, time‐dependent photocurrent generation, along with persistent photoconductivity, which is attributed to the interfacial charge trapping. Through the advantage of synaptic functionality, a trained convolutional neural network successfully recognizes noise‐reduced circularly polarized images of handwritten alphabetic characters with better than 89.7% accuracy.

AbstractThe simultaneous optimization of sluggish reaction kinetics and mass transfer in bifunctional oxygen electrocatalysts for air cathodes remains a great challenge. This study utilizes CoAl‐layered double hydroxide as a metal precursor to fabricate a bifunctional oxygen electrocatalyst, denoted as CoAlOXD‐Thin. This electrocatalyst features a specific core–shell structure of Co species, which grows on an aerophilic and conductive substrate composed of Al2O3 and carbon. It is successfully demonstrated that the thickness of Co@Co3O4 core–shell structure can be easily controlled by selecting different precursors and the combination of Co core and Co3O4 shell optimizes the adsorption strength of intermediates, leading to enhanced catalytic performance. Additionally, the Al species plays a dual role. It not only facilitates the mass transfer of oxygen species but also hinders the 2e− pathway of oxygen reduction reaction, leading to improved selectivity. Notably, the Zn–air batteries utilizing CoAlOXD‐Thin demonstrate an impressive peak power density of 216.2 mW cm−2, a high specific capacity of 800.8 mAh gZn−1, and excellent cycling stability and reversibility, surpassing those of the Pt/C + RuO2 catalyst. This study presents a novel approach to enhance air cathode performance by optimizing reaction kinetics and mass transfer through precursor design.

AbstractLong‐chain organic halide salts are widely used in perovskite‐based optoelectronic devices for surface passivation owing to their capability to interact with the surface defects of perovskites. Here, aluminum oxide (AlOx) is introduced via atomic layer deposition onto octylammonium iodide (OAI) to exploit the benefits of organic halide salts without generating undesired defects. The devices incorporating AlOx on OAI‐treated perovskite (OAI/AlOx) show enhancement in both device performance and photo‐stability compared to those with only treatment. A diffusion of aluminum from AlOx into the perovskite through surface characterization contributes to a uniform photo‐generated carrier transport in both the surface and the bulk of the perovskite absorber. In addition, it is revealed that light‐induced two‐dimensional perovskite formation on OAI/AlOx. This may be ascribed to preventing the loss of OA cations due to the presence of AlOx, leading to a decrease in the number of iodine anions which suppresses the light‐induced degradation of corresponding devices. Consequently, the devices show over 24% efficiency and retain their efficiency over 1000 hours under continuous light illumination.

AbstractDespite their ultrahigh specific capacity, lithium‐rich layered oxide cathodes are still plagued by challenges such as poor cycle stability and notorious voltage decay, which are primarily attributed to surface issues such as the release of lattice oxygen and interfacial side reactions. In this study, a facial strategy of gradient fluorination is adopted to construct a thin but robust LiF‐rich cathode electrolyte interface (CEI), highly enhancing the stability of the interface of lithium‐rich oxides. Experimental results and theoretical calculations both demonstrate that the stable CEI not only promotes oxygen participation in redox reactions and simultaneously inhibits oxygen release and structural transition, but also facilitates the transport kinetics of lithium ions. As a result, the gradient fluorinated lithium‐rich cathode delivers highly enhanced rate performance (133 mAh g−1 at 5 C), superior cycling stability with a capacity retention of 81.9% after 100 cycles at 1 C (250 mAh g−1), and alleviated voltage fade (only 1.75 mV per cycle). Moreover, a unique formation mechanism for LiF‐rich surfaces is proposed according to theoretical calculations. This work not only provides a fresh understanding of the CEI formation mechanism, but also show a promising avenue for designing LiF‐rich CEIs applicable to other layered oxide cathodes.

AbstractWaste tyres are a global problem, with 1.5 billion being generated annually. To reduce this problem, a circular economy for tyres should be developed. This requires the incorporation of recycled tyre rubber in tyre products. Yet, most recycled rubber is of insufficient quality. Recycled rubber must react sufficiently well with virgin rubber to be elastically effective in the 3D crosslinked network. Although a broad range of devulcanization techniques have been developed, many recycled‐virgin rubber blends show significant reductions in stiffness compared with their virgin counterparts. This paper demonstrates that micromechanical models for filler reinforcement can be used to evaluate whether recycled rubber behaves in an elastically effective manner. Furthermore, mechanical devulcanization of ground tyre rubber (GTR) by solid‐state shear milling was shown to produce a recycled rubber powder that is elastically effective when blended with virgin natural rubber (vNR). These blends match the equivalent virgin rubber stiffness, despite high‐recyclate content (30/70 vNR/GTR). The addition of nanofillers (carbon black and graphene nanoplatelets) to these blends was evaluated to see how they compared with virgin compounds and filler reinforcement theories. This process may allow for incorporation of devulcanized rubber into existing products, promoting a circular economy for high‐value rubber recycling.

AbstractThe existing footwear ecosystem is not environmentally friendly and thus poses a threat to sustainability. In this article, our objective is to take a product‐service systems approach to propose alternative footwear consumption scenarios from a sustainability viewpoint and investigate the perspective of Indian consumers toward the proposed scenarios. To this end, we initially conducted a comprehensive literature review to explore alternative consumption scenarios in the realm of fashion products. This step led to the development of 10 alternative footwear consumption scenarios that focus on maintenance and repair, takeback, assembly, customization, personalization, advice and consultancy, rent, sequential share, swap, and functionality. Next, we adopted the focus group interview methodology to investigate the perception of Indian consumers toward the 10 alternative footwear consumption scenarios, which can inform the footwear industry's product development, marketing strategies, and sustainability initiatives. Our results indicate that while the participants found the consumption scenarios to be interesting and practical, they feel that the proposed scenarios may prove to be more feasible for comparatively expensive footwear products because of the associated logistics costs. Furthermore, the participants pointed out a few cultural as well as hygiene‐related issues that may hinder the adoption of certain alternative footwear consumption scenarios.

AbstractBackgroundDistinguishing between central nervous system lymphoma (CNSL) and CNS infectious and/or demyelinating diseases, although clinically important, is sometimes difficult even using imaging strategies and conventional cerebrospinal fluid (CSF) analyses. To determine whether detection of genetic mutations enables differentiation between these diseases and the early detection of CNSL, we performed mutational analysis using CSF liquid biopsy technique.MethodsIn this study, we extracted cell‐free DNA from the CSF (CSF‐cfDNA) of CNSL (N = 10), CNS infectious disease (N = 10), and demyelinating disease (N = 10) patients, and performed quantitative mutational analysis by droplet‐digital PCR. Conventional analyses were also performed using peripheral blood and CSF to confirm the characteristics of each disease.ResultsBlood hemoglobin and albumin levels were significantly lower in CNSL than CNS infectious and demyelinating diseases, CSF cell counts were significantly higher in infectious diseases than CNSL and demyelinating diseases, and CSF‐cfDNA concentrations were significantly higher in infectious diseases than CNSL and demyelinating diseases. Mutation analysis using CSF‐cfDNA detected MYD88L265P and CD79Y196 mutations in 60% of CNSLs each, with either mutation detected in 80% of cases. Mutual existence of both mutations was identified in 40% of cases. These mutations were not detected in either infectious or demyelinating diseases, and the sensitivity and specificity of detecting either MYD88/CD79B mutations in CNSL were 80% and 100%, respectively. In the four cases biopsied, the median time from collecting CSF with the detected mutations to definitive diagnosis by conventional methods was 22.5 days (range, 18–93 days).ConclusionsThese results suggest that mutation analysis using CSF‐cfDNA might be useful for differentiating CNSL from CNS infectious/demyelinating diseases and for early detection of CNSL, even in cases where brain biopsy is difficult to perform.

Published: July 2023

AbstractThis theoretical article aims to recognize the potential of intersectionality theory for understanding well‐being during childhood and adolescence, particularly from a community psychology perspective. Following the tenets of intersectionality, the article analyses and proposes three relevant dimensions for community psychologists, researchers and professionals interested in studying and intervening in children's and adolescents' well‐being. Those dimensions consider (1) adultism as an intersecting power axis fundamental for understanding well‐being, (2) the acknowledgment of diversity in well‐being conceptions and experiences as a critical issue and (3) the need for advancing studies that involve praxis and engagement in transformative changes for child and adolescent well‐being.

AbstractPleurotus ostreatus is an edible fungus with high nutritional value that uses industrial and agricultural lignocellulosic residues as substrates for growth and reproduction. Understanding their growth metabolic dynamics on agro‐industrial wastes would help to develop economically viable and eco‐friendly biotechnological strategies for food production. Thus, we used UHPLC/MS/MS and GNPS as an innovative approach to investigate the chemical composition of two strains of P. ostreatus, coded as BH (Black Hirataki) and WH (White Hirataki), grown on sisal waste mixture (SW) supplemented with 20 % cocoa almond tegument (CAT) or 20 % of wheat bran (WB). Metabolite dereplication allowed the identification of 53 metabolites, which included glycerophospholipids, fatty acids, monoacylglycerols, steroids, carbohydrates, amino acids, and flavonoids. This is the first report of the identification of these compounds in P. ostreatus, except for the steroid ergosterol. Most of the metabolites described in this work possess potential biological activities, which support the nutraceutical properties of P. ostreatus. Thus, the results of this study provide essential leads to the understanding of white‐rot fungi chemical plasticity aiming at developing alternative biotechnologies strategies for waste recycling.
