Hydrogenation‐Driven Metal Dispersion and Catalytic Enhancement of Borophane‐Supported Single‐Atom Catalysts for Electrochemical Nitrogen Reduction
Authors: Sun Yi‐Bing , Dang Jing‐Shuang , Zhao Xiang 
Published: October 2024

AbstractThe present study delves into electrochemical nitrogen reduction reaction (NRR) for ammonia synthesis using borophane‐supported single‐atom catalysts (SACs) through density functional theory (DFT) calculations. In comparison to previously reported borophene, which serves as a potential substrate for SACs in NRR, hydrogenated borophane, especially borophane‐2H(B5H2), not only prevents metal aggregation, resulting in stable atomically dispersed metal centers, but also enhances catalytic activity by modulating the metal's charge state. Among all candidates, atomic tungsten anchored on W1/borophane‐2H(B5H2) displays the most favorable NRR activity and product selectivity.

Published: October 2024

AbstractDouble polymer networks (DNs) consist of two interpenetrating polymer networks and can offer properties that are not merely a sum of the parts. Here, we report an elastic DN made from two supramolecular polymers (SMPs) that consist of the same poly(n‐butyl acrylate) (BA) backbone. The two polymers feature different non‐covalent binding motifs, which form dynamic, reversible cross‐links. The polymers were prepared by reversible addition−fragmentation chain‐transfer polymerization of n‐butyl acrylate and either the self‐complementary hydrogen‐bonding motif 2‐ureido‐4[1H]pyrimidinone, or the 2,6‐bis(1′‐methylbenzimidazolyl)pyridine ligand, which forms complexes with metal ions. The supramolecular DN made by these components combines features of the single networks, including high thermal stability and resistance to creep. The DN further exhibits excellent healability and displays a higher extensibility and a higher toughness than its constituents. The mechanical characteristics of the DN can be further enhanced by selectively pre‐stretching one of the networks, which is readily possible due to the reversible formation of the supramolecular cross‐links and their orthogonal stimuli‐responsiveness.

AbstractBackgroundThe objective of this study was to elucidate the frequency and cytologic features of positive peritoneal washing cytology (PWC) in cervical gastric‐type adenocarcinoma (GAS) and to clarify the clinical significance of positive PWC.MethodsThe authors analyzed cases from their institution between 1991 and 2023 in which patients underwent surgery and PWC. The study included 62 patients who had cervical GAS (1991–2023; including seven patients with adenocarcinoma in situ and 26, 15, nine, and five patients with International Federation of Gynecology and Obstetrics 2018 stage I, II, III, and IV disease, respectively) and 100 patients who had usual‐type endocervical adenocarcinoma (2007–2023; including 65, 15, and 20 patients with stage I, II, and III disease, respectively). The frequency of positive PWC results and cytologic features was assessed, and correlations between positive PWC results and clinicopathologic factors were examined, including prognosis, in the GAS group.ResultsPositive PWC results were significantly more frequent in patients who had GAS at 24% (15 of 62 patients) compared with 7% (seven of 100 patients) in those who had usual‐type endocervical adenocarcinoma. The cytologic features of GAS included distinct cellular atypia (enlarged nuclei, nuclear irregularity) and frequent formation of spherical clusters (10 of 15 cases) without the golden‐yellowish mucus commonly seen in cervical smears. A positive PWC result in GAS was significantly correlated with larger tumor size, parametrium invasion, lymph node metastasis, and elevated carbohydrate antigen 19‐9 levels. In patients with stage I GAS, the PWC‐positive group had significantly shorter disease‐free survival and overall survival compared with the PWC‐negative group.ConclusionsPositive PWC findings are frequent in cervical GAS and are associated with pathologic factors indicative of tumor growth and progression. In patients who have stage I GAS, positive PWC results may indicate a poor prognosis, warranting further investigation.

AbstractThe modularization of metal‐organic‐frameworks (MOFs) powders is a crucial to bringing out the excellent properties of MOFs to industrial applications in water treatment, gas adsorption/separation and catalytic fields. To improve their practical application and recyclability, we propose a hybrid composite of biocompatible MOFs decorated on self‐supported three‐dimensional (3D) printed polyurethane acrylate (PUA) for wastewater treatment. In this study, we select Bi‐based MOFs with good visible‐light response and chemical stability as photocatalysts, two MOFs, bismuth gallate (Bi‐GA) and bismuth ellagic acid (Bi‐EA), are loaded into the mesh‐like PUA template by in‐situ growth method. And then, these two composites, PUA/Bi‐GA and PUA/Bi‐EA are used for the photocatalytic treatment of Rhodamine‐B (RhB) dye. The results demonstrate that PUA/Bi‐EA could reach the highest removal rate of 98.08 % under acidic conditions in 4 hours. The excellent performance should be attributed to unique structure that endow their high adsorption capacity for dyes, further, the adsorbed dye as a sensitizer enhances the utilization of sun‐light. This study provides a new composite for advanced photocatalytic water treatment and other environmental purification.

Published: October 2024

AbstractThe red/green cyanobacteriochrome (CBCR) slr1393g3 exhibits a quantum yield of only 8 % for its forward photoconversion, significantly lower than other species from the same CBCR subfamily. The cause for this reduced photoconversion is not yet clear, although in the related NpR6012g4 dark‐state structural heterogeneity of a paramount Trp residue has been proposed to cause the formation of nonproductive subpopulation. However, there is no such information on the equivalent residue in slr1393g3, W496. Here we use solid‐state NMR to explore all possible sidechain rotamers of this Trp residue and their local interactions at the atomic level. The indole nitrogen (Nϵ1) is used as an NMR probe, achieved by site‐specific 15N‐indole labeling of a quadruply Trp‐deleted variant and trehalose vitrification technique. The data reveal a set of seven indole rotamers of W496 with four distinct environments for the Nϵ1‐H group. Only a minority population of 20 % is found to retain the π‐stacking and hydrogen‐bonding interactions with the chromophore in the dark state that has been assigned to account for complete forward photoconversion. Our results demonstrate the direct role of W496 in modulating the forward quantum yield of slr1393g3 via rearrangement of its sidechain rotameric conformations.
Mitochondrial Function and Dysfunction in White Adipocytes and Therapeutic Implications
Authors: Wang Fenfen , Huynh Phu M. , An Yu A. 
Published: October 2024

AbstractFor a long time, white adipocytes were thought to function as lipid storages due to the sizeable unilocular lipid droplet that occupies most of their space. However, recent discoveries have highlighted the critical role of white adipocytes in maintaining energy homeostasis and contributing to obesity and related metabolic diseases. These physiological and pathological functions depend heavily on the mitochondria that reside in white adipocytes. This article aims to provide an up‐to‐date overview of the recent research on the function and dysfunction of white adipocyte mitochondria. After briefly summarizing the fundamental aspects of mitochondrial biology, the article describes the protective role of functional mitochondria in white adipocyte and white adipose tissue health and various roles of dysfunctional mitochondria in unhealthy white adipocytes and obesity. Finally, the article emphasizes the importance of enhancing mitochondrial quantity and quality as a therapeutic avenue to correct mitochondrial dysfunction, promote white adipocyte browning, and ultimately improve obesity and its associated metabolic diseases. © 2024 American Physiological Society.Compr Physiol14:5581‐5640, 2024.

AbstractAs a gluten‐free cereal with high nutritional properties, pearl millet [Pennisetum glaucum (L.) R. Br.] has been increasingly regarded as an alternative dryland resilient food crop with enriched grain nutritional value. This paper explores the potential of single‐kernel near‐infrared (SKNIR) spectroscopy combined with multivariate analysis for rapid and non‐destructive evaluation of protein, moisture, fat, fiber, and ash contents of pearl millet grains. Samples harvested from two consecutive years (2021 and 2022) were evaluated under dryland and irrigated conditions in Kansas State University, Agricultural Research Center, Hays (ARCH), KS and were analyzed using SKNIR and conventional laboratory methods. Model calibrations were developed using partial least squares regression. Results showed satisfactory performance of models with standard errors cross‐validation of 1.04%, 0.17%, 0.39%, 0.21%, and 0.16%, respectively, for protein, moisture, fat, fiber, and ash content. The findings suggest that SKNIR can be a potential tool for high‐throughput pearl millet composition screening efficiently, which will assist breeders and grain processors to optimize grain properties and enhance the grain quality and products.
A method to spatially assess multipass spray deposition patterns via UV fluorescence and weed population shifts

Published: October 2024

AbstractSpray deposition patterns from agricultural sprayers are traditionally sampled discretely along a field transect accounting for 0.5% or less of the treated area. Such methods may not fully capture the dimensional variability inherent in large‐scale, multiple‐pass spray applications, especially evident from an agricultural spray drone (ASD). This study investigated the utilization of UV‐fluorescent dye and nighttime aerial imaging techniques to assess large‐scale, multipass spray deposition patterns. Accuracy of digital hue from UV‐fluorescent photography to predict deposition of proxy dye was confirmed via fluorometry assessed intensity levels of extracted UV‐fluorescent dye from 384 Petri dishes placed prior to treatment. Results showed that ASD applications, regardless of nozzle type, exhibited greater spatial variability within the target area compared to ride‐on sprayer applications, primarily due to overapplication. Additionally, the ASD generated spray drift to adjacent nontarget areas that was at least three times more than that of ride‐on and spray‐gun sprayers. Multipass deposition was further assessed via in situ smooth crabgrass infestation following treatment with quinclorac or topramezone by multipass ASD or hand‐held, four‐nozzle spray boom. Weed infestation annotated from overlaid grids with 9.3‐dm2 ground resolution inconsistently detected spatial heterogeneity between transects assessed along the center and edge of each sprayer pass. The ASD controlled smooth crabgrass 11% more than the hand‐held sprayer, albeit with an 18% increase in spray drift to nontarget areas, similar to the UV‐fluorescence study. Digitally assessed average hue of fluorescence photography appears to be a viable method to assess multidimensional and continuous spatial relationships of spray deposition.

Published: October 2024

AbstractSpring wheat (Triticum aestivum L.) is a popular bread wheat with high milling and baking requirements. Vernalization is not required for spring wheat, which allows for fast growth under manipulated conditions. This experiment's objective was rapid development of inbred lines of hard red spring wheat throughout the off‐season and preserve enough genetic variability to perform selection. A total of 1575 F2 heads from three distinct populations were randomly harvested in the field‐season 2021. To break seed dormancy, seeds were held for 2 days at 0°C. Three breeding cycles were performed through single seed descent under manipulated growth condition during the off‐season 2021–2022. We were able to harvest plant materials as quickly as 54 days after planting in comparison to 110 days average field season. We lost a total of 36.4% during the three off‐season fast advancement generations and 711 genotypes reached the F5:6 generation with enough seed to perform a partially replicated small plot yield trial at two locations during the 2022 field‐season. Response traits collected included grain yield, grain protein, plant height, days to heading, and bacterial leaf streak (Xanthomonas transluens) disease severity. Heritability of collected traits varied between 0.61 and 0.92. Although we had considerable loss during the speed breeding, we were able to identify superior genotypes compared to the parents.

Published: October 2024

AbstractTurfgrass systems are some of the most ubiquitous forms of perennial agricultural systems. People interact with them on a daily basis, and they provide a wide variety of social and environmental benefits. Over the past two decades, turfgrass systems have been increasingly seen as coupled human‐natural systems, which has prompted new avenues of research across multiple areas from breeding to management. While this human‐natural systems framework has been helpful, the rapid development and integration of technology (e.g., smart sensors, robotic mowers) and the push for nature‐based solutions and green infrastructure have changed the landscape significantly for turfgrass systems. With this in mind, the current work advocates for the adoption of a new framework, social–ecological–technological systems (SETS), to better understand where turfgrass systems research is situated now and, more importantly, what directions it could go in the future.

Published: October 2024

AbstractThis research sheds light on the impact of the International Organization for Standardization (ISO) 14001:2015 standard, particularly in its role in driving life cycle perspective (LCP) and effectively integrating product‐oriented environmental management practices (POEMPs) within manufacturing sectors. Addressing this research gap, our analysis utilizes a worldwide sample of 1951 medium and large enterprises from the Thomson Reuters environmental, social and governance (ESG) database to compare the integration of POEMPs, in certified and non‐certified companies, before and after the ISO14001 standard update with a quantitative approach. The findings reveal a higher adoption rate of the seven POEMPs analyzed among certified companies before the publication of the standard. However, its LCP‐focused revision elevates only the implementation of three of them. This highlights a predominant selection effect over the intended treatment effect of the new standard and challenges the assumption that certification to the new version represents an advance in companies' product‐related environmental strategies. The originality of this research lies in its critical analysis of the practical outcomes of ISO14001:2015, pointing the disconnection between certification and the incorporation of POEMPs into environmental management systems. It highlights the need to strengthen implementation mechanisms and provides a nuanced understanding of the role of the standard in driving environmental progress.

Published: October 2024

AbstractThis study examines the impact of green bond issuance on companies' environmental social and governance (ESG) performances and greenwashing behavior of a sample of Chinese‐listed firms. We find that the issuance of green bonds significantly bolsters corporate ESG performance through the financing and signaling mechanisms. The moderating effect of policy uncertainty proves to have a mutually reinforcing effect on the impact of green bonds on ESG performance. By signaling the commitment to green and low‐carbon transformation, the issuance of green bonds offsets the negative effects of policy uncertainty on firm's ESG performance. Extended analysis on greenwashing discerns no notable differences among firms with different polluting conditions and politically connected levels. The issuance primarily improves environmental (E) and social (S) dimensions, with negligible influence on the governance (G) aspect of ESG. Our findings suggest that a potential propensity of greenwashing in China's green bond market.

AbstractThe catalytic functionalization of CO2 into high‐value compounds comprises a promising approach to mitigate its atmospheric content and sustainable generation of fine chemicals. In this respect, covalent organic frameworks (COFs) offer great potential in carbon dioxide capture and utilization. Herein, we report application of a crystalline, nanoporous 2D COF (ET‐BP‐COF) obtained by condensation of 4,4′,4′′,4′′′‐(ethene‐1,1,2,2‐tetrayl) tetraaniline (ET‐NH2) and 2,2′‐bipyridyl‐5,5′‐dialdehyde (BP‐CHO) building blocks for strategic utilization of CO2. The ET‐BP‐COF features a unique 2D kagome (kgm) topology composed of hexagonal and triangular 1D channels decorated with bipyridine sites, which were exploited for covalent anchoring of eco‐friendly, alkynophilic Cu(I) by the post‐synthetic method. The Cu(I) engrafted COF was applied as a recyclable catalyst for coupling CO2 with alkynes to generate two high‐value compounds, α‐alkylidene cyclic carbonates (α‐ACCs) and 2‐oxazolidinones. Notably, Cu(I)@ET‐BP‐COF demonstrated excellent catalytic performance for transforming propargylic amine and CO2 to 2‐oxazolidinone, an essential building block for antibiotics. Besides, an efficient transformation of propargylic alcohols to generate α‐ACCs, valuable commodity chemicals, has been achieved by utilizing carbon dioxide. Further, detailed theoretical simulations disclosed the insight mechanistic path of Cu(I) catalyzed coupling of CO2 and alkynes to produce 2‐oxazolidinones and α‐ACCs. Significantly, the Cu(I)@COF was reusable for multiple cycles without losing framework rigidity and catalytic performance. This study showcases the potential application of ET‐BP‐COF for stable anchoring of eco‐friendly metals as catalytic sites for effective utilization of CO2 to produce two high‐value products, 2‐oxazolidinones and α‐ACCs, under mild atmospheric conditions.

Published: October 2024

AbstractThe restoration of alpine grasslands has garnered significant attention across various sectors. Historically, natural restoration has been the primary approach for grassland recovery, characterized by its prolonged duration. To expedite the recovery of degraded grasslands, it is essential to identify the limiting factors of restoration, enabling efficient and rapid recovery. Appropriate nitrogen (N) addition levels have been considered a potential strategy to enhance the recovery of grassland ecosystems and augment their ecological benefits. However, the effectiveness of N addition in alpine grassland restoration remains debated. This study investigated the impact of five N addition levels (CK: control [0 g/m2]; LN: low N [5 g/m2]; MN: medium N [10 g/m2]; HN: high N [15 g/m2]; SN: severe N [20 g/m2]) and two experimental approaches (N addition once per year [NPY] and three times per year [NTY] at the same dosages) on plant and soil properties and the maximum restoration capacity of alpine meadows. Our findings reveal three key insights: The level of N addition was the primary factor influencing aboveground plant biomass and coverage. Plant diversity decreased under the NTY regime and increased with NPY in the Bayinbruck grassland. N addition significantly altered soil properties, including pH, salinity, soil organic carbon (SOC), soil‐available phosphorus (AP), and soil total phosphorus (TP). Notably, soil TP, total nitrogen (TN), and AP substantially impacted plant community structure and diversity. Based on structural equation model (SEM) and analysis of variance (ANOVA), optimal grassland restoration was achieved with the HN (15 g/m2) treatment under NPY and the MN and HN (10 and 15 g/m2) treatments under NTY. Overall, our study offers crucial insights into the conservation, management, and restoration of grassland ecosystems on the Bayinbruck Plateau. It underscores the significance of N addition effects on plant communities, vegetation restoration, and soil properties.
