Published: October 2024

AbstractManganese‐based compounds have the characteristics of high theoretical capacity, low cost and stable performance, thus become a research hotspot for cathode materials of zinc‐ion batteries (ZIBs). However, in the process of charging and discharging, it is accompanied by problems such as structural collapse and low conductivity, which resulted in severe capacity degration during cycles. In this paper, a kind of Zn2+ doped MnO2 hollow cube cathode material (Zn−MnO2) was prepared by self‐sacrificing template method. The Zn2+ doped in MnO2 crystals can induce oxygen vacancies in the structure, thereby improving the structural stability ion diffusion coefficient and electrical conductivity of the material. After 100 cycles at 0.3 A g−1, the high specific capacity of 281.2 mA h g−1 is still maintained. Through ex‐situ XPS and ex‐situ XRD tests, the mechanism of charge‐discharge process was discussed. The results show that the storage mechanism of Zn‐MnO2 is H+ and Zn2+ insertion/removal and Mn3+/Mn2+ two‐electron reaction pathway. The total state density (TDOS) and partial state density (PDOS) of Zn−MnO2 and MnO2 further demonstrated that the doping of Zn2+ enhanced the electron conductivity and is beneficial to the electron transfer during the electrochemical reaction.
Strategic Design of Anion‐Responsive Triarylboranes Exhibiting Colorimetric and Fluorometric Red‐Shift for Sensing and Optoelectronic Applications
Authors: Takeda Youhei 
Published: October 2024

AbstractTriarylboranes (TABs) have been employed as colorimetric and/or fluorometric anion sensors. The majority of TAB‐based anion sensors exhibit blue‐shift modes of absorption and photoluminescence (PL) or turn off of PL, attributed to the intrinsic electronic polarity of the trivalent boron unit in their molecular designs. In this Concept article, I introduce a novel approach to modulating the photophysical properties of TABs toward a red‐shift mode by balancing the dual, opposing roles of the amine‐bridged TAB (phenazaborine). This molecular design strategy enables significant changes in color and emission response to anions, shifting to the lower energy regime in solution. Additionally, this approach is applicable to the solid‐state modulation of PL in films and organic light‐emitting diodes (OLEDs).

Published: October 2024

AbstractCovalent organic frameworks (COFs) are robust, porous materials with well‐defined structures that have been employed for gas separation, photoluminescence, sensing, energy storage, and heterogeneous catalysis. This review summarizes recent progress in the use of COFs as a versatile platform for heterogeneous photocatalytic cross‐dehydrogenative coupling (CDC) reactions, which are an efficient and clean methodology for the formation of C−C or C−P bonds. We review the synthesis of these photocatalytic COFs, correlating their catalytic performance with their structures and photoelectric properties.
Shining light on the shadows: The role of corruption control in the relationship between board composition and SDG disclosure
Authors: Pinheiro Alan Bandeira , Lopes Gabriele , Mazzo Gabriel Gusso 
Published: October 2024

AbstractThis paper investigates how corruption control moderates the relationship between board composition and Sustainable Development Goals (SDG) disclosure. We analyze a sample of 269 companies from Mediterranean capitalism countries (Portugal, Greece, Italy, Spain, Malta, and Cyprus) combining a symmetric method (panel data analysis) and an asymmetric approach (fuzzy‐set qualitative comparative analysis). Our findings show that larger boards enhance SDG disclosure and female presence negatively impacts SDG disclosure. Corruption control is a driver of SDG disclosure, and the effect of board size on SDG disclosure is greater when companies are operating in countries with low rates of corruption. This the first paper that investigates the relationship between board composition and SDG disclosure, highlighting the moderating effect of controlling corruption at the country level. Managers should be aware that some board characteristics drive greater SDG disclosure. Additionally, governments can support SDG disclosure by combating corrupt practices in their countries, and by creating support mechanisms for companies to incorporate SDGs into business strategies.

AbstractThe challenge of moving to a carbon‐free energy economy is highlighted in the context of technology and materials restrictions. Many technologies needed for the so‐called energy transition depend on critical metals such as platinum, lithium, iridium and cobalt. Here we focus on solid borohydride salts as hydrogen carriers, studying catalysts for hydrogen release. We combine metal 3D printing technology and a Raney‐type leaching process to make structured macroscopic catalyst/reactor monoliths of cobalt, aluminium and stainless steel with well‐defined micropores. Remarkably, the blank catalyst samples, which are made only from aluminium and stainless steel (Al‐SS), show high activity and, importantly, high stability in borohydride hydrolysis, with no mass loss and no surface poisoning. The batch results are confirmed in a continuous setup running for 96 h. Catalyst performance is attributed to the stable porous structure, the mechanical stability of the stainless steel macrostructure, and the presence of accessible Al(OH)x sites. This research shows a clear contribution to sustainability based on multi‐factor comparison: The Al‐SS catalyst outperforms the state‐of‐the‐art on mechanical and chemical durability, it is both PGM‐free and CRM‐free, and its preparation follows a simple, scalable and low‐waste procedure.

Published: October 2024

AbstractTransition metal‐catalyzed cross‐coupling reaction between organometallic reagents and electrophiles is a potent method for constructing C(sp2)−C(sp3) bonds. Given the characters of organometallic reagents, cross‐reductive coupling is emerging as an alternative strategy. The resurgence of electrochemistry offers an ideal method for electrochemical reductive of cross‐coupling electrophiles. Inspired by the mechanism of electrochemical metal hydride, our study proposed that Ni−H electrochemically catalyze the hydroarylation coupling of unactivated alkenes with aryl halides. 1,1‐Diarylalkanes can be produced effectively. This method have advantages including mild conditions, excellent regioselectivity, and satisfactory yields.
A Hybrid Multiobjective Control Strategy Based on Combination of Modulated Model Predictive Control and Phase‐Shifted Modulation for a Unidirectional Five‐Level Rectifier

Published: October 2024

ABSTRACTThe unidirectional multilevel rectifier has immense potential in high‐power medium‐voltage industrial applications. This paper proposes a multiobjective control method based on the combination of optimal‐vector‐pair modulated model predictive control (OVP‐M2PC) and a phase‐shifted modulation strategy for a unidirectional five‐level rectifier. This strategy takes both of the inductor current tracking and capacitor voltage balancing as the control objectives. First, an optimal vector pair is determined based on the AC‐side current variation rate, and then, through combining the calculated action duration of OVP with carrier phase‐shifted modulation, inductor current tracking is achieved. Second, capacitor voltage balancing control is carried out by compensating for the duty cycles which also decouples the input current tracking and output capacitor voltage balance control. Compared with traditional FCS‐MPC, under the proposed control strategy, complex cost function calculation and weighting factor tuning are not required, which much reduced computational burden. Multiobjective control is achieved with better performance in both steady‐state and dynamic conditions. The superiority of the proposed strategy over traditional FCS‐MPC are validated through simulations and hardware experiments.

Published: October 2024

AbstractINTRODUCTIONWidowhood and divorce are extremely stressful life events that are associated with dementia, but the neurobiological underpinnings of this risk remain unknown. Amyloid beta (Aβ) load may explain influences of chronic stress, commonly seen in disruptive marital transitions, on cognitive decline.METHODSWe examined whether Aβ quantified by tracer uptake on positron emission tomography mediates associations between marital dissolution and executive functioning and episodic memory performance using data from 543 cognitively normal (CN) participants from the Alzheimer's Disease Neuroimaging Initiative.RESULTSMarriage dissolution was associated with increased Aβ burden (β = 0.56; P = 0.015) and worse memory performance (β = –0.09; P = 0.003). Aβ levels were a significant mediator for the relationship between marriage dissolution and memory (average causal mediation effect = –0.007; P = 0.029).DISCUSSIONFindings suggest that stressful life events, such as the dissolution of one's marriage, might exert an effect on Alzheimer's disease proteinopathy, which may subsequently influence poor cognition.Highlights
Marital dissolution was associated with increased amyloid beta (Aβ) and memory declines.
Aβ burden mediated associations between marital dissolution and memory.
Findings were robust to potential non‐linear influences of age.
Mediation results were not observed when stratifying marital groups by sex.

ABSTRACTThis study investigates the effect of agmatine on reducing mortality, neurobehavioral alterations, infarct size, and expression of pro‐inflammatory cytokines in mice subjected to bilateral carotid thrombosis. Under pentobarbital anesthesia, the left common carotid artery was exposed to 6% FeCl3. Thirty‐two days later, the same procedure was performed on the right common carotid artery. Subsequently, Agmatine (100 mg/kg) was administered 15 min after the second procedure, and in another experimental group, the dose of Agmatine was repeated at 72 h. Administration of agmatine extended survival in ischemic animals up to 72 h for the single‐dose group and up to 96 h for the repeated‐dose group, without significant increases in neurological deficits or infarct area size. This neurobehavioral effect was also observed in sham animals treated with agmatine. In ischemic animals, agmatine administration improved digging behavior and reduced recovery times, consistently shorter in those animals treated with repeated doses. RT‐PCR analyses revealed a positive regulation of the cytokine IL‐1β in agmatine‐treated animals, which has been associated with recovery stages. The results suggest that the observed effect may be attributed to the multiple interactions of agmatine with ischemic cascade events, highlighting its anti‐inflammatory role.

AbstractIndigenous Knowledge, Practice, and Belief Systems (IKPBS) are an ecological and cultural framework with which Indigenous communities have (and continue to) adaptively manage their land since time immemorial. In the current context of climate change and colonial forest and fire management in the western US, Indigenously‐led ecological research and cultural revitalization offers a path forward where tribal sovereignty of land stewardship is maintained and the resiliency of natural systems are reestablished. We describe our process of developing an Indigenous‐Directed Research (IDR) partnership to study xánthiip (Karuk for black oak, Quercus kelloggii), a Karuk cultural focal species, in the context of Karuk‐led forest restoration. We first outline our process of IDR by describing how this partnership was established, research questions and methodologies were co‐developed, IKPBS were centered, and utility to tribal forest restoration processes were prioritized. The primary product of this partnership was a culturally responsive black oak monitoring protocol to assess black oak tree quality over time. We describe how this protocol was developed including conducting semi‐structured qualitative interviews with Karuk cultural practitioners, translating qualitative interviews to field protocol metrics, consulting with research partners, testing for field feasibility, and sharing back to the local community through field training and youth curriculum development. Second, we analyzed plot data collected from the implementation of the black oak protocol using a two‐eyed seeing approach that ensured our ecological findings had cultural relevance for future Karuk‐led forest stewardship. Through this analysis we described the dominant black oak tree typologies based on their traits of importance as identified by Karuk cultural practitioners and research collaborators. All natural resources research takes place on Indigenous land. By outlining the steps of this transdisciplinary IDR partnership, we provide a framework for centering IKPBS, respecting Indigenous land sovereignty, and centering Indigenous leadership in ecological research and knowledge co‐development.
The Paradoxical Effect of Repeated Body Checking on Subjective Uncertainty
Authors: Ben Zaken Linn Mor , Kalanthroff Eyal , Weinbach Noam 
Published: October 2024

ABSTRACTObjectiveBody checking is considered a behavioral expression of the core psychopathology of eating disorders (EDs), namely, overvaluation of body weight and shape. Compulsive checking is motivated by a desire to increase a sense of certainty regarding feared outcomes. Paradoxically, studies showed that repeated checking acts to reduce certainty, forming a vicious cycle. No previous study examined whether the same principle applies for body checking. This study filled this gap by examining the causal effect of repeated body checking on memory certainty regarding checked body parts.MethodIn a laboratory‐based study, 77 female participants without an ED checked the size and shape of six body parts. Their objective memory regarding which body part was last checked, and subjective certainty about this memory were assessed. Then, one group of participants continued to engage in repeated body checking, and another group repeatedly checked a neutral object. Finally, all participants completed the six body parts checking procedure again, and their objective memory and memory certainty were re‐assessed.ResultsIn both checking groups, objective memory regarding the last body part checked was unaffected by the type of checking performed. Importantly, certainty about memory dropped considerably only among those in the repeated body‐checking group.DiscussionThe findings provide the first empirical evidence of a paradoxical effect demonstrating that repeated body checking reduces certainty about checked body parts. The study implies that repeated body checking reduces the quality of information obtained through checking and, as such, could potentially motivate further checking.

Published: October 2024

AbstractSolar power has been regarded as the ultimate green‐energy source because of its inexhaustibility and eco‐friendliness. The solar‐driven water‐splitting technology for green hydrogen production is considered to be one of effective ways for solar energy harvesting and storage, which may provide solutions for the energy crisis and environmental issues. In the past decades, great progress has been achieved in this area. Photoelectrochemical (PEC) water splitting is especially promising for the production of solar fuels because of expected large‐scale industrial application. Silicon (Si), as an ideal candidate for the photoelectrode, is the most suitable material for the PEC device in industrial photocatalytic water splitting because of its abundance, mature fabrication technology, and suitable band gap. Here, we give a systematic review on the recent progress for Si‐based photoelectrodes for water splitting with a focus on the industrial application. Particularly, the strategies, such as band‐alignment control, morphology design, and surface engineering, are summarized to enhance the PEC performance and durability for practical application. Furthermore, the perspective for the design of commercial Si‐based PEC devices with high PEC performance, long‐term stability, large‐size, and low cost are given at the end, which shall guide the development of PEC water splitting for industrial application.

AbstractLow levels of essential mineral elements such as cobalt, copper, and iron, in organisms reduce immune function, increasing the chances of parasitic infection. This phenomenon has been demonstrated widely in domestic animals but rarely in wildlife. In this study, we used data from 7‐ to 9‐month‐old roe deer (Capreolus capreolus), living in two different populations facing contrasting environmental conditions (Trois‐Fontaines and Chizé), to investigate whether the parasitic and immunological statuses could be related to essential element status. Between 2016 and 2019, we collected feces to measure parasite burdens (gastrointestinal and pulmonary nematodes), blood to measure immunological parameters (globulins and white blood cells), and hair to assess the concentration of 11 essential elements (calcium [Ca], chromium [Cr], cobalt [Co], copper [Cu], iron [Fe], magnesium [Mg], manganese [Mn], potassium [K], molybdenum [Mo], selenium [Se], and zinc [Zn]). The results showed first heterogeneity in the individual phenotypes of the two populations. Roe deer with low body mass had high concentrations of all the essential elements (in particular, Ca, Fe, Cu, K, and Mn), a high parasitic burden, and high concentrations of globulins. An association between high concentrations of essential elements and a high parasite burden was found at the two study sites despite markedly different environmental conditions. A relationship between essential element concentrations and immune parameters was also detected, with more basophils and globulins being associated with high concentrations of essential trace elements (i.e., Ca, Fe, Cu, and, to a lesser extent, Se, Cr, and Zn). These results suggest that young individuals with low body mass and high parasitism may select feeding resources rich in mineral elements, which may improve their ability to control the infestation and/or mitigate the negative consequences of parasites by maintaining immune system functions.
Crystal Structure, Phase Transition and Dielectric Behaviors of One‐dimensional Organic‐inorganic Bromoargentate Hybrids of [Et‐dabco]2Ag2Br4

Published: October 2024

AbstractA new haloargentate hybrid, [Et‐dabco]₂Ag₂Br₄ (1) (Et‐dabco+=1‐Ethyl‐1,4‐diazabicyclo[2.2.2]octan‐1‐ium), has been successfully synthesized by a solution diffusion method and characterized using microanalysis, single crystal X‐ray diffraction, variable‐temperature powder X‐ray diffraction (PXRD), differential scanning calorimetry (DSC), and dielectric spectra. The crystal structure of 1 at 273 K contains one‐dimensional (1D) anionic [Ag₂Br₄]2− chains, with the [Et‐dabco]+ cations embedded in the gaps between the inorganic chains. Hybrid 1 underwent a reversible structural phase transition (SPT) at around 464.5 K on heating, and the Pawley refinement revealed similar crystal structures in the low‐ and high‐temperature phases. The SPT endows 1 with switchable and bistable dielectric properties. Combined with previous studies, it was revealed that the self‐assembly of silver halide (AgX) with the lower rotational energy barrier of 1‐alkyl‐1,4‐diazabicyclo[2.2.2]octan‐1‐ium in solution probably achieves new phase transition materials.

AbstractCyclobutanes have attracted significant interest in medicinal chemistry because of their unique structure and potential advantages in pharmacological properties. Nevertheless, 1,2‐disubstituted cyclobutanes remain underrepresented, both in the general chemical space and in fragment‐based drug discovery libraries. In this study, a two‐diversification‐point library of cyclobutanesulfonamides was synthesized through a hyperbaric [2+2] cycloaddition reaction between ethenesulfonyl fluoride and tert‐butyl vinyl ether as the key step. The sulfonyl fluoride was subsequently transformed into various sulfonamides, whereas the tert‐butyl ether was converted into carbamates and triazoles to synthesize a fragment library. Overall, this synthesis contributes to addressing the underrepresentation of 1,2‐disubstituted cyclobutane fragments, making a valuable addition to the field of fragment‐based drug discovery.
