AbstractCovalent organic framework (COF) membranes feature with well‐developed 1D in‐plane pores and parallelly arranged 2D interlayer gallery, presenting promising platform for precise separations. However, it remains a formidable challenge to construct and regulate membrane channels at angstrom scale. Herein, pH‐sensitive dopamine is taken advantage to elaborately engineer the spatial size of 1D/2D channels in COF membranes for the separations of alkali metal ions. Acid treatment allows monomolecular dopamine to segment 1D in‐plane pores of COF membrane, achieving ultramicroporous regulation from 1.25 nm to 0.71 nm, which enables high selectivity of 18.7 for K+/Li+ separation. Molecular dynamics simulations reveal the higher dehydration degree, weaker channel‐cation interaction and faster diffusion coefficient of K+ than Li+. For alkaline treatment, dopamine self‐polymerizes to form nanoparticles between COF layers, which enlarges the 2D interlayer channels from 0.33 nm to 0.45 nm in COF membrane, enabling high‐permeance ion/molecule separations. The water permeance increases 86.7% to 404 L m−2 h−1 bar−1, without the sacrifice of membrane sieving ability. Both cation separation and ion/molecule separation performances outperform the current state‐of‐the‐art membranes. This dopamine‐mediated channel engineering strategy may provide the new insights for the design of membrane channels in precise separations.

AbstractA methodology to access stereoisomeric sets of products bearing multiple stereogenic centers is still a significant challenge in asymmetric catalysis. We present herein our experimental studies on the stereodivergent synthesis of chiral hydrobenzofuran‐fused pyrrolidines with three stereogenic centers via organocatalytic asymmetric dearomative cyclization and epimerization process. Chiral bifunctional thiourea catalyst could successfully promote the enantioselective dearomatization cyclization of 2‐nitrobenzofurans with o‐hydroxy aromatic aldimines, which enabled the synthesis of (3S,3aR,8bR)‐hydrobenzofuran[3.2]pyrrolidines in 79–92% yields with >20:1 stereoselectivities and 93–>99% enantio‐selectivities. While catalytic amount of DBU could induce the direct intramolecular epimerization of (3S,3aR,8bR)‐hydrobenzofuran[3.2] pyrrolidines to its diastereomers (3R,3aR,8bR)‐hydrobenzofuran[3.2] pyrrolidines in 72–87% yields without loss of stereoselectivities. The mechanistic pathways of the epimerization process were investigated by a series of control experiments study. This work provides an alternative and forward solution for the stereodivergent preparation of functionalized pyrrolidines with potential bioactivities.

Published: October 2024

AbstractSolvent‐free manufacturing is crucial for fabricating high‐performance sulfide‐electrolyte‐based all‐solid‐state lithium batteries (ASSLBs), with advantages including side reaction inhibition, less contamination, and practical scalability. However, the fabricated sulfide electrolytes commonly suffer from brittleness, limited ion transport, and unsatisfactory interfacial stability due to the uncontrolled dispersion of the sulfide particles within the polymer binder matrix. Herein, a “solid‐to‐liquid” phase transition strategy is reported to fabricate flexible Li6PS5Cl (LPSCl) electrolytes. The polycaprolactone (PCL)‐based binder (PLI) with phase‐transition characteristics fills the gap of LPSCl particles and tightly grafts on the particle surface via ion‐dipole interaction, bringing a thin and compact electrolyte membrane (80 µm). The simultaneously high Li‐ion conducting and electron insulating nature of PLI binder facilitates Li‐ion transport and ensures good interfacial stability between electrolyte and anode. Consequently, the sulfide electrolyte membrane exhibits high ionic conductivity (8.5 × 10−4 S cm−1), enabling symmetric and full cells with 10 and 2.5 times longer cycling life compared with that of the cells with pristine LPSCl electrolyte, respectively. The demonstrated strategy is versatile and can be extended to ethylene vinyl acetate copolymer (EVA) that also brings enhanced electrochemical performance. The thin sulfide electrolyte with high interfacial stability potentially facilitates dendrite‐free ASSLBs with high energy density.

AbstractIn this concise review, the recent advancements in fully inkjet‐printed (IJP) indium‐gallium‐zinc‐oxide (IGZO) thin‐film transistors (TFTs) over the past years are discussed. IGZO has replaced hydrogenated amorphous silicon (a‐Si:H) as the primary channel material for liquid‐crystal display TFTs and has gained further attention due to the solution processability of IGZO inks. Despite the longstanding practice of printing IGZO for approximately fifteen years, the realization of fully inkjet‐printed devices, including both dielectric and electrode components, represents a recent milestone in research, potentially heralding a cost‐effective era for IGZO transistors. In this review, following an introductory exposition of IGZO, the focus is on the different ink formulations, currently deployed for solution‐processed IGZO devices, the intricacies of the printing procedure involved are delineated, and ongoing research endeavors pertaining to the printing of dielectrics and electrodes for such devices are expounded upon.

AbstractHardware integration with biological synaptic function is the key to realizing brain‐like computing. Resistive Random Access Memory (RRAM), with a similar structure to biological synapses, are important candidate for the simulation of biological synaptic function. In this work, Ga2O3 film as a functional layer of RRAM is prepared by the solution method, and an RRAM‐based photo‐synaptic device with an Ag/Ga2O3/Si structure is constructed subsequently. The device exhibits excellent bipolar resistive switching characteristics, with the merits of a large storage window and long retention time. Furthermore, the devices generated excitatory postsynaptic currents (EPSC) and paired‐pulse facilitation (PPF) behaviors under light pulse stimulation, enabling the simulation of synaptic plasticity. The transformation of synaptic behavior from short‐term memory (STM) to long‐term memory (LTM) is achieved by observing the spike‐duration dependent plasticity (SDDP), spike‐intensity dependent plasticity (SIDP), spike‐number dependent plasticity (SNDP) and spike‐rate dependent plasticity (SRDP) characteristics of photonic synapses under different conditions. The device also simulates the process of successive “learning‐forgotten‐remembering”, revealing that RRAM‐based photonic synapses have great potential in the fields of artificial visual perception and memory storage.

Published: October 2024

AbstractWith its high energy density, lithium metal battery technology encounters empirical challenges such as pulverization and dendrite growth. These can hinder the achievement of long lifespans. To address these challenges, it is important to optimize the lithium charge behavior. Here, the determination of the appropriate structural conditions and processes to prevent the accumulation of lithium ions on the lithium surface is discussed. Employing a hierarchical structure of polymeric macro/mesopores at the lithium interface, the favorable behavior of lithium ions and the reaction process is monitored. And the way of alloying process is proposed, revealing lithium ion accepted alloyable metals make to lithium‐metal intermetallic compounds. The well‐distributed alloyable metals in the unidimensional polymeric interface have sufficient capacity to accommodate and transport lithium ions. This emphasizes the need for innovative strategies to address irregular lithium nucleation and enhance lithium metal battery technology.

AbstractThe exceptional thermal stability and conductivity of lithium bis(fluorosulfonyl)imide (LiFSI) have made it a preferred salt for lithium‐ion batteries (LIBs). However, the corrosion of aluminum (Al) current collectors by LiFSI at low potentials (3.8 V vs Li/Li+) poses a persistent challenge, hindering the application of LiFSI in 4 V‐class LIBs. Herein, 2,2,2‐trifluoroethyl methanesulfonate (TFMS) is proposed as a versatile co‐solvent to address the issue of Al current collector corrosion. It is demonstrated that incorporating TFMS into a conventional LiFSI‐based carbonate electrolyte can precisely tailor the Li+ solvation structure by hydrogen bonding interactions with dimethyl carbonate (DMC) solvent. This weakens the coordination between DMC and Li+ while increasing the participation of FSI− anions in the primary solvation shell, effectively suppressing the Al current collector caused by free FSI− anions attacking. Furthermore, TFMS and FSI− synergically induce the formation of an inorganic‐rich and compact cathode electrolyte interphase, significantly avoiding undesired side reactions. As a result, the TFMS‐electrolyte enables 1.2 Ah‐graphite||NCM811 (LiNi0.8Co0.1Mn0.1O2) pouch‐cells to achieve 89.9% capacity retention with high average Coulombic efficiency of >99.9% for 200 cycles at a cut‐off voltage of 4.4 V, opening up opportunities for the development of advanced high‐voltage LIBs.

AbstractIntroductionFall injuries are the second leading cause of traumatic injury and death for all US workers and are a leading injury concern for the Department of the Air Force (DAF). Bundled interventions can improve the likelihood of injury reduction, especially in large, heterogeneous working populations. In 2013, the DAF implemented the “Air Force Fall Prevention Focus,” a bundled intervention of prevention efforts designed to reduce occupational fall injury events among DAF members. The purpose of this study is to describe the burden and risk factors associated with fall injuries and evaluate the effectiveness of the Fall Prevention Focus in reducing the burden of fall injuries.MethodsThe National Institute for Occupational Safety and Health (NIOSH) partnered with the US Air Force Safety Center (AFSEC) to examine the impact of the Fall Prevention Focus as a bundled intervention. Injury events included a narrative description of the injury event, demographics, work environment, job tasks, and other structured details. Descriptive statistics and pre–post longitudinal modeling were used to evaluate changes in fall injury rates.ResultsThe Fall Prevention Focus Implementation (2013–2018) resulted in an annual 10.4% (95% confidence interval [CI]: 8.5%, 12.2%) reduction, and a 6‐year cumulative 48.3% (95% CI: 41.4%, 54.3%) reduction in fall injury event rates by 2018.DiscussionSafety in the DAF involves a comprehensive approach. Documenting the impact of the Fall Prevention Focus may help translate these findings to improve fall prevention efforts in other sectors of the military and high fall‐risk industries in the private sector, such as construction.
Was the abolition of the Aboriginal and Torres Strait Islander Commission an act of dispossession?
Authors: Crumpen Tui 
Published: October 2024

AbstractThe Aboriginal and Torres Strait Islander Commission (ATSIC) has been described as one of the most comprehensive regional and national governance structures for Indigenous people in Australia. This paper looks briefly at its operational life between 1990 and 2005 and focusses on its abolition, arguing that this was an act of dispossession. The ATSIC was, for its time, a remarkable achievement for both the nation state and Indigenous people. Acting as an institution to both represent and deliver services to Indigenous people, the ATSIC model was, and could have remained, a powerful organisation for enacting critical change. Constructed and then removed by the nation state, the ATSIC's abolition dispossessed Indigenous people of a political framework dedicated to organising an Indigenous collective voice. This dispossession, different from earlier waves of dispossession from land, resources and cultural freedoms, can be understood by the application of critical Indigenous institutional analysis. Through its own structure and electoral representation, the ATSIC had made visible the quest for self‐determination and gave Indigenous people decision‐making powers not since replicated. Redirecting ATSIC's limited decision making back to government exposed the illusion of control. The ATSIC's abolition left a void in the growing capability of Indigenous people to self‐determine and a gaping hole in Australia's national political imagination.

AbstractAchieving high‐efficiency perovskite solar cells (PSCs) hinges on the precise control of the perovskite film crystallization process, often improved by the inclusion of additives. While dimethyl sulfoxide (DMSO) is traditionally used to manage this process, its removal from the films is problematic. In this work, methyl phenyl sulfoxide (MPSO) was employed instead of DMSO to slow the crystallization rate, as MPSO is more easily removed from the perovskite structure. The electron delocalization associated with the benzene ring in MPSO decreases the electron density around the oxygen atom in the sulfoxide group, thus reducing its interaction with PbI2. This strategy not only sustains the formation of a crystallization‐slowing intermediate phase but also simplifies the elimination of the additive. Consequently, the optimized PSCs achieved a leading power conversion efficiency (PCE) of 25.95 % along with exceptional stability. This strategy provides a novel method for fine‐tuning perovskite crystallization to enhance the overall performance of photovoltaic devices.

AbstractPectinases are commonly industrially synthesized by molds. This study aimed to optimize pectin lyase synthesis by a bacterium, Pseudomonas fluorescens, using both the one‐factor‐at‐a‐time (OFAT) method and response surface methodology. First, on optimization of pectin lyase fermentation by the OFAT method, the effects of pectin, peptone, yeast extract, (NH4)2SO4, pH, and salts were investigated. The highest pectin lyase activity was determined to be 28.63 U/mL at pH 8, 30°C, with 1% (w/v) pectin and 0.14% (w/v) (NH4)2SO4 concentration at the 90th hour. The effect of substrate inhibition on the microbial growth was also investigated, and the results showed that the process can be described by noncompetitive inhibition model. The values of kinetic constants were determined as µm = 0.175 h−1, KS = 6.931 g/L, and, KI = 6.932 g/L by nonlinear regression analysis. It was reported that pectin lyase enzymes exhibited peak activity at 50°C and pH 8. Finally, response surface methodology (RSM) was utilized to optimize pH, concentrations of ammonium sulfate, and pectin, which were chosen as independent variables. The interactions between these variables were also examined. According to RSM, the optimum values of the parameters to achieve a maximum pectin lyase activity of 35.62 U/mL were determined to be pH 7.97, 1.25% (w/v) pectin concentration, and 0.25% (w/v) (NH4)2SO4 concentration.

Published: October 2024

AbstractAs a prevalent psychiatric disorder, the etiology of depression remains largely elusive, necessitating further investigation into its pathophysiological underpinnings. Notably, the comorbidity of depression with other mental health conditions and chronic diseases often presents alongside gastrointestinal symptoms. Research on the microbiome‐gut‐brain axis (MGBA) has emerged as a promising avenue for elucidating the pathophysiology of depression. In this study, bibliometric analysis tools, including HistCite, VOSviewer, CiteSpace, and the bibliometrix R package, were employed to comprehensively explore the MGBA‐depression connection. A comprehensive survey identified 980 relevant publications concerning the MGBA‐depression relationship, with a significant increase in research output observed since 2014. This analysis pinpointed five key factors within the MGBA‐depression domain: cytokines, maternal separation, neuroinflammation, probiotics, and the vagus nerve. The insights presented herein offer valuable perspectives on prevailing research models that investigate the intricate interplay among the microbiome, gastrointestinal system, and brain within the context of depression. Based on these findings, future investigations should prioritize developing microbial‐based interventions and innovative therapeutic modalities aimed at alleviating depression. By leveraging interdisciplinary collaboration and enhancing our understanding of MGBA–depression connections, we can pave pathways toward more effective treatments. Furthermore, improving outcomes for individuals with depression may be achieved by deepening our comprehension of the complex relationships between depression itself, the gut‐brain axis, and gastrointestinal microbiota.

AbstractThe safeguarding of animal welfare holds a deep‐rooted history within public institutions and legislative structures, with the objective of enhancing the comfort and overall wellbeing of animals throughout the entire experimental process. It is paramount to harmonize the enhancement of animal welfare with medical research practices, as this is pivotal in mitigating factors that impede modeling precision and prioritizing their welfare. This commitment has nurtured innovation in advanced experimental methodologies and welfare evaluation techniques. The classic 3Rs principle‐replacement, reduction, and refinement‐serves as a fundamental cornerstone for advancing the welfare of model animals. The establishment of appropriate metrics for animal welfare, rooted in the 3Rs principle, will propel progress in related fields. This review delves into the evolution of animal ethics and the 3R principles, alongside strategies to elevate the welfare of various model animals utilized in neuroscience, encompassing non‐human primates, rodents, zebrafish, and other species. The aim of this review is to clarify the notion of welfare in this context and to evaluate the merits and constraints of utilizing model animals in neuroscience research. This, in essence, may contribute to bolstering animal protection and standardizing their use in research endeavors. Additionally, the pursuit of novel modeling methodologies is imperative to provide superior alternatives for neuroscience research.

Published: October 2024

AbstractThe challenging task of designing biopharmaceutical downstream processes is initially to select the type of unit operations, followed by optimizing their operating conditions. For complex flowsheet optimizations, the strategy becomes crucial in terms of duration and outcome. In this study, we compared three optimization strategies, namely, simultaneous, top‐to‐bottom, and superstructure decomposition. Moreover, all strategies were evaluated by either using chromatographic Mechanistic Models (MMs) or Artificial Neural Networks (ANNs). An overall evaluation of 39 flowsheets was performed, including a buffer‐exchange step between the chromatography operations. All strategies identified orthogonal structures to be optimal, and the weighted overall performance values were generally consistent between the MMs and ANNs. In terms of time‐efficiency, the decomposition method with MMs stands out when utilizing multiple cores on a multiprocessing system for simulations. This study analyses the influence of different optimization strategies on flowsheet optimization and advices on suitable strategies and modeling techniques for specific scenarios.
