AbstractThe last 20 years have seen many publications investigating porous solids for gas adsorption and separation. The abundance of adsorbent materials (this work identifies 1608 materials for CO2/N2 separation alone) provides a challenge to obtaining a comprehensive view of the field, identifying leading design strategies, and selecting materials for process modeling. In 2021, the empirical bound visualization technique was applied, analogous to the Robeson upper bound from membrane science, to alkane/alkene adsorbents. These bound visualizations reveal that adsorbent materials are limited by design trade‐offs between capacity, selectivity, and heat of adsorption. The current work applies the bound visualization to adsorbents for a wider range of gas pairs, including CO2, N2, CH4, H2, Xe, O2, and Kr. How this visual tool can identify leading materials and place new material discoveries in the context of the wider field is presented. The most promising current strategies for breaking design trade‐offs are discussed, along with reproducibility of published adsorption literature, and the limitations of bound visualizations. It is hoped that this work inspires new materials that push the bounds of traditional trade‐offs while also considering practical aspects critical to the use of materials on an industrial scale such as cost, stability, and sustainability.

Published: January 2023

AbstractThe application of photoelectrochemical (PEC) water splitting is limited by the sluggish surface oxygen evolution reaction (OER) kinetics. OER kinetics can be effectively improved through cocatalyst engineering. However, the tardy transfer process and serious recombination of carriers are the key factors restricting the cocatalyst development. Taking BiVO4 as an example, a Co‐modified heme film rich in large conjugated ring structures is introduced onto the photoanode surface using a solvothermal method. This film functions as an efficient cocatalyst. It considerably reduces the surface overpotential, promotes the transfer of photogenerated holes, and boosts the kinetics of OER by specifically affecting the formation of OOH*. Simultaneously, the formed CoOV bonds induce strong interaction at the photoanode/cocatalyst interfaces, reducing the recombination of photogenerated carriers. Consequently, the onset potential of the optimized photoanode decreases from 0.45 to 0.07 V and the photocurrent density at 1.23 V versus reversible hydrogen electrode boosts to 5.3 mA cm−2. This work demonstrates a facile strategy for designing cocatalysts to obtain rapid hole transfer capability and reduced carrier recombination for improved PEC performance.

AbstractThe introduction of high economic value species like giant freshwater prawn (GFWP) makes culture‐based fisheries (CBF) a substantial source of income and simultaneously supports the livelihood development of rural fishers in Sri Lanka. However, this CBF strategy has been implemented without any scientific basis, and therefore, this paper evaluated the stocking and production data of GFWP in Sri Lankan reservoirs from 2011 to 2017 to identify interventions for achieving future sustainability. We used two distinct approaches to appraise the CBF strategies practised so far and decrypt the identified shortcomings in the initiatives. The first approach was a straight‐head univariate generalized additive model (GAM) analysis of stocking density (SD), production (PRD), recapture efficiency (RCE) and reservoir surface area (A). The latter approach was a hybrid PCoA‐GAM for detained data mining for a better management perspective. The relationships among SD, PRD RCE and A were significant and, stochastic PRD and RCE were reasoned by the biased stocking practices identified in the GAM analysis. The hybrid PCoA‐GAM is seemingly robust in predicting and explaining the deviances of PRD and RCE of GFWP CBF. Results indicated that the present practices of CBF of GFWP in Sri Lankan reservoirs suffer several weaknesses, overstocking in minor and understocking in both medium and major reservoirs are primarily under consideration, which includes inter alia, the need for effective tools for identification of suitable reservoirs, the inefficient harvesting practices, non‐optimal SDs coupled with the possible vulnerability of stocked postlarvae to high mortalities. According to the study, we prefer to set the optimum SD as 1500 PLs ha−1 to all reservoirs. A comprehensive study has been launched for the enhancement of CBF of GFWP in Sri Lankan reservoirs.
A trait‐based approach to determining principles of plant biogeography
Authors: Vasconcelos Thais 
Published: January 2023

AbstractLineage‐specific traits determine how plants interact with their surrounding environment. Unrelated species may evolve similar phenotypic characteristics to tolerate, persist in, and invade environments with certain characteristics, resulting in some traits becoming relatively more common in certain types of habitats. Analyses of these general patterns of geographical trait distribution have led to the proposal of general principles to explain how plants diversify in space over time. Trait–environment correlation analyses quantify to what extent unrelated lineages have similar evolutionary responses to a given type of habitat. In this synthesis, I give a short historical overview on trait–environment correlation analyses, from some key observations from classic naturalists to modern approaches using trait evolution models, large phylogenies, and massive data sets of traits and distributions. I discuss some limitations of modern approaches, including the need for more realistic models, the lack of data from tropical areas, and the necessary focus on trait scoring that goes beyond macromorphology. Overcoming these limitations will allow the field to explore new questions related to trait lability and niche evolution and to better identify generalities and exceptions in how plants diversify in space over time.

AbstractIntroductionThe relationship between initial cognitive symptoms and subsequent rate of clinical decline is important in clinical care and the design of dementia clinical trials.MethodsThis retrospective longitudinal, autopsy‐confirmed, cohort study among 2426 participants in the National Alzheimer's Coordinating Center database included Alzheimer's disease (AD) pathology, n = 1187; Lewy body pathology (LBP), n = 331; and mixed pathology (AD‐LBP), n = 904. The predominant initial cognitive symptom was assessed clinically. Linear mixed models evaluated the longitudinal outcome of the Clinical Dementia Rating‐Sum of Boxes (CDR‐SB) score.ResultsNon‐amnestic initial symptoms had a faster rate of decline than amnestic symptoms in all three groups. Language symptoms had a faster rate of decline in all three groups. Executive symptoms had a faster rate of decline than amnestic in AD and AD‐LBP. There was a similar trend for visuospatial symptoms in AD‐LBP.DiscussionInitial cognitive symptoms, despite varied underlying pathology, are a predictor of longitudinal functional outcomes among dementias.Highlights
Initial non‐amnestic symptoms had a faster rate of longitudinal cognitive and functional decline on the Clinical Dementia Rating‐Sum of Boxes (CDR‐SB) scores than amnestic symptoms among Alzheimer's disease, Lewy body pathology, and mixed neuropathology.
Given the relative size of CDR‐SB changes in Alzheimer's disease clinical trials, clarifying the nature of initial symptoms could be an important variable in ensuring appropriately designed clinical trials.

AbstractBackgroundWe aimed to prepare a non‐invasive, reproducible, and controllable rat model of intracerebral hemorrhage with focused ultrasound (FUS).MethodsA rat intracerebral hemorrhage (ICH) model was established by combining FUS and microbubbles (μBs), and edaravone was used to verify whether the free radical scavenger had a protective effect on the model. The brain tissue of each group was sectioned to observe the gross histology, blood–brain barrier (BBB) permeability, cerebral infarction volume, and histopathological changes.ResultsCompared with the FUS group, the BBB permeability was significantly increased in the FUS + μBs (F&B) group (p = 0.0021). The second coronal slice in the F&B group had an obvious hemorrhage lesion, and the FUS + μBs + edaravone (F&B&E) group had smaller hemorrhage areas; however, ICH did not occur in the FUS group. The cerebral infarction volume in the F&B group was significantly larger than that in the FUS group (p = 0.0030) and F&B&E group (p = 0.0208). HE staining results showed that nerve fibrinolysis, neuronal necrosis, microglia production, and erythrocytes were found in both the F&B group and the F&B&E group, but the areas of the nerve fibrinolysis and neuronal necrosis in the F&B group were larger than the F&B&E group.ConclusionsA rat ICH model was successfully prepared using the μBs assisted FUS treatment, and edaravone had a therapeutic effect on this model. This model can be used to study the pathophysiological mechanism of ICH‐related diseases and in preclinical research on related new drugs.

AbstractMetal‐free perovskites (MFPs) with flexible and degradable properties have been adopted in flexible X‐ray detection. For now, figuring out the key factors between structure and device performance are critical to guide the design of MFPs. Herein, MPAZE‐NH4I3 ⋅ H2O was first designed and synthesized with improved structural stability and device performance. Through theoretical calculations, the introducing methyl group benefits modulating tolerance factor, increases dipole moment and strengthens hydrogen bonds. Meanwhile, H2O increases the hydrogen bond formation sites and synergistically realizes the band nature modulation, ionic migration inhibition and structural stiffness optimization. Spectra analysis also proves that the improved electron‐phonon coupling and carrier recombination lifetime contribute to enhanced performance. Finally, a flexible and degradable X‐ray detector was fabricated with the highest sensitivity of 740.8 μC Gyair−1 cm−2and low detection limit (0.14 nGyair s−1).

AbstractThe low efficiency triplet emission of hybrid copper(I) iodide clusters is a critical obstacle to their further practical optoelectronic application. Herein, we present an efficient hybrid copper(I) iodide cluster emitter (DBA)4Cu4I4, where the cooperation of excited state structure reorganization and the metallophilicity interaction enables ultra‐bright triplet yellow‐orange emission with a photoluminescence quantum yield over 94.9 %, and the phonon‐assisted de‐trapping process of exciton induces the negative thermal quenching effect at 80–300 K. We also investigate the potential of this emitter for X‐ray imaging. The (DBA)4Cu4I4 wafer demonstrates a light yield higher than 104 photons MeV−1 and a high spatial resolution of ≈5.0 lp mm−1, showing great potential in practical X‐ray imaging applications. Our new copper(I) iodide cluster emitter can serve as a model for investigating the thermodynamic mechanism of photoluminescence in hybrid copper(I) halide phosphorescence materials.

Published: January 2023

AbstractIn order to improve the slow‐release effectiveness of waterborne polymer coated fertilizers, an environment‐friendly coated urea was developed by zeolite and waterborne polymer of starch soluble, polyvinyl alcohol, sodium carboxymethyl cellulose, and chitosan. The properties of different mesh and content of zeolite on the membranes and the slow‐release property of coated urea were investigated. Zeolite decreased water vapor, ammonium permeability and porosity of waterborne polymer with an increased ammonium adsorption, and contributed to improve the slow‐release effectiveness of coated urea. In particular, zeolite‐modified waterborne polymer of 200 mesh and 3% content had best effect with 10.8%, 16.5%, and 59.8% decrease of water absorption capacity, water vapor permeability and ammonium permeability, 17.7% increase of water contact angles. Zeolite‐modified waterborne polymer coated urea for the coating contents of 7% had the best effect on the nutrient accumulate release rate. Therefore, zeolite‐modified waterborne polymers have potential to improve the slow‐release effectiveness of coated urea.

Published: January 2023

AbstractIn the current scenario, many automotive and aerospace industries have exaggerated replacement of most of the metal parts with polymers to achieve the pursuit of lightweight thereby to reduce fuel consumption and carbon emission. Foam injection molding (FIM) is among one of the cost‐effective approaches to produce lightweight polymer products. During FIM, stringent control over various processing parameters is crucial to ensure the precision and reliability of molded parts. This work aims toward the investigation of cavity pressure and its effect on microstructure or cell morphology in chemical blowing agent mixed polypropylene (PP) foams produced by FIM. In particular, effect of varying injection temperature, injection speed and plasticization parameters (screw rotation speed and back pressure) have been examined on the cavity pressure profiles and its conforming influence on cell nucleation and growth have been discussed acutely. The results of this study indicate that various process parameters significantly influence the trajectory of cavity pressure profile during FIM which in turn critically decides structural uniformity of foamed product.
Identifying imperilled fish species and potential causes of decline in the Himalaya biodiversity hotspot

Abstract

Despite the global nature of the aquatic biodiversity crisis, drivers of extirpation vary among regions, making local‐level data collection crucial for adaptive management in understudied regions like the Himalaya Biodiversity Hotspot (HBH). As human population growth, economic development and environment change accelerate across the HBH it is important to identify imperilled species and determine any ecological traits that predispose them to extirpation.
In the present study, Monte Carlo analysis was used to determine fish species with significant range reductions (‘significantly declining species’) from the 1980s to the 1990s, and from the 1990s to the 2010s, at 38 sites on Nepal’s Kaligandaki–Narayani River (KNR). Relative to a null model under which all species were equally likely to lose individuals between time periods, distributions of 16 of 83 species declined significantly across at least one of the two time periods, and two species, Hamilton’s baril (Opsarius bendelisis) and the trout barb (Raiamas bola), declined across both.
Mid‐water fishes native to both lowlands and hills were most likely to experience range reduction. International Union for the Conservation of Nature Red List status was not representative of actual population trends, highlighting the critical role of local, long‐term data collection and management strategies for effective conservation.
Opsarius bendelisis and R. bola urgently need protection in the KNR to stem current population declines. Conservation efforts here should focus on speciose lower‐elevation sites, where many of the 14 other significantly declining species also occur. Overfishing is likely to have contributed to species declines, suggesting that the network of terrestrial protected areas already in place across the HBH can aid aquatic biodiversity conservation efforts owing to their status as fish sanctuaries. Rivers such as the KNR represent a unique opportunity to conserve an intact, albeit threatened, fish species, before human pressures lead to widespread extirpations of the type documented in many areas of the world.

AbstractWe report a rhodium(I)‐catalyzed asymmetric cyclohydroformylation reaction of 1,6‐enynes with formaldehyde. The reaction of 1,6‐enynes with formaldehyde in the presence of a cationic Rh(I) catalyst, such as [Rh(cod)2]+OTf−, and a chiral biaryl diphosphine led to asymmetric cyclohydroformylation to produce aldehydes with higher‐order structures highly enantioselectively. This transformation procedure is applicable to a variety of enynes, with wide compatibility in various atoms liking between the alkyne and alkene parts, substituents at the alkyne terminus, and substituents at the alkene part, being converted to newly formed aldehydes in 14% to 90% yields with 50% to 98%ee. The products were further transformed with various nucleophiles to alcohols, an amine, and a diene without loss of chirality at their γ‐position.
The “Greenberg Controversy” and the Interdisciplinary Study of Global Linguistic Relationships**
Authors: Kaplan Judith R. H. 
Published: January 2023

AbstractThis paper examines the controversy that followed the 1987 publication of Joseph Greenberg's book, Language in the Americas, attending to the role of language and linguistic research within overlapping disciplinary traditions. With this text, Greenberg presented a macro‐level tripartite classification that opposed then dominant fine‐grained analyses recognizing anywhere from 150 to 200 distinct language families. His proposal was the subject of a landmark conference, examining strengths and weaknesses, the unpublished proceedings of which are presented here for the first time. For specialists in the anthropological and comparative‐historical study of Indigenous American languages, Greenberg's intervention highlighted the tension between language, conceived as an abstract object of study, and languages, understood to be carriers of specific cultural knowledge. For physical anthropologists and archaeologists, his theory was initially fortuitous on programmatic, substantive, and methodological grounds. The essay will show how interdisciplinary appeals were figured by supporters as a virtue, and by critics as a vice. The essay further highlights ethical reasons for integrating historical narratives of science and the humanities.
Synthesis and photophysical investigation of Schiff base as a Mg2+ and Zn2+ fluorescent chemosensor and its application
Authors: Mei Xin , Luo Wentao , Li Hui , Pu Shouzhi 
Published: January 2023

AbstractIn view of the fluorescent switching properties and anti‐fatigue properties of diarylethene, a diarylethene fluorescent chemosensor for the immediate detection of zinc ion (Zn2+) and magnesium ion (Mg2+) in acetonitrile was synthesized in this article. The structure of 1o was determined by performing spectroscopy and elemental analysis. The presence of Zn2+ or Mg2+ made the chemosensor 1o show an obvious “turn‐on” fluorescent signal (bright yellow‐green for Mg2+ and bright cyan for Zn2+). The fluorescent change caused by the 1:1 binding of 1o and Zn2+ or Mg2+ might be due to hindering the excited‐state intramolecular proton transfer (ESIPT) process, which were bolstered by Benesi–Hildebrand analysis, Job's plot curves, proton nuclear magnetic resonance (1H‐NMR) titration and mass spectrometry. The limits of detection were acquired from the standard curve plots for Mg2+ at 44.6 nM and for Zn2+ at 14 nM. Based on the fluorescent behaviors, a logic gate was constructed with the emission intensity at 528/518 nm as output signal, the ultraviolet‐visible (UV‐vis) lights, Mg2+/Zn2+ and EDTA as input signals. Exogenous Zn2+ and Mg2+ fluorescent bioimaging were performed on Hela cells with 1o, indicating its potential application in biodiagnostic analysis. In particular, 1o was manufactured into test paper, and Zn2+ or Mg2+ can be conveniently, efficiently and qualitatively identified by the fluorescent color variation of the test strips.
Study on the interaction of two quinazoline derivatives as novel PI3K/mTOR dual inhibitors and anticancer agents to human serum albumin utilizing spectroscopy and docking
Authors: Chen Jiangang , Bian Xiaoli , Zhang Sanqi , Yang Guangde 
Published: January 2023

AbstractInteractions of human serum albumin (HSA) with two structurally similar quinazoline derivatives, S1 and S2, which are potential anticancer drugs acting on PI3K/mTOR targets, were investigated in vitro utilizing multiple spectroscopy as well as molecular docking. The fluorescence quenching study demonstrated that HSA fluorescence could be statically quenched by S1 and S2 through the formation of an HSA–drug complex. Furthermore, the details of the binding site number, binding constant, as well as the thermodynamic parameters, were estimated at 298, 303, and 310 K. The results revealed that hydrogen bond interactions, as well as van der Waals forces, were the predominant factors responsible for binding HSA to S1 or S2. Synchronous fluorescence and ultraviolet (UV) absorption spectra suggested that S1 and S2 had little effect on the polarity of the microenvironment and conformation of HSA. Energy transfer from HSA to S1 or S2 most probably occurred. The docking study revealed that S1 and S2 were able to bind to the hydrophobic cavity that was located in the HSA subdomain IIA and formed varying numbers of hydrogen bonds with amino acid residues nearby. Due to the subtle difference in the chemical structure, the binding of S1 and S2 to HSA was slightly different.
