Authors: Singh Hardeep , Mulvaney Michael J. , Bashyal Mahesh , Singh Kulpreet 
Published: September 2024

AbstractProhexadione calcium is a growth regulator, which manages excessive vine growth in peanut (Arachis hypogaea L.) by reducing shoot internode length. To test the effect of prohexadione calcium on peanut, a field experiment was conducted at the West Florida Research and Education Center in Jay, FL, during 2021 and 2022. The objective was to determine peanut response at different rates (untreated control, 70, 105, 140, and 175 g a.i. ha−1 of prohexadione calcium). Data were collected on yield, peg strength, above‐ and belowground biomass, plant height, and total sound mature kernels. Additionally, return on investment for prohexadione calcium application was also calculated. Prohexadione calcium application resulted in significant reduction of peanut plant height. The application rate of 105 g a.i. ha−1 resulted in significantly greater normalized difference vegetation index as compared to untreated control. Belowground, aboveground, and total biomass did not significantly differ between the 140 g a.i. ha−1 rate and untreated control. However, peanut peg strength increased significantly at the 140 g a.i. ha−1 treatment compared to the untreated control. Peanut yield ranged from 6.65 to 7.15 Mg ha−1 among different treatments; however, the differences among treatments were not significant. Similarly, the total sound mature kernels and return on investment did not differ significantly under different prohexadione calcium treatments. Considering that peanut response to prohexadione calcium is difficult to observe in small plots, it is important to test the effect of prohexadione calcium on peanut production under on‐farm large plot conditions.

AbstractBackgroundPrevious studies have shown that job strain is associated with low birthweight (LBW), preterm birth (PTB), and small for gestational age (SGA). We conducted a scoping review and meta‐analysis to assess the association between job strain and adverse pregnancy outcomes.MethodsA literature search was performed on PubMed. We included English‐language studies that examined the association between job strain (based on the Karasek demand‐control model) and pregnancy outcomes. We excluded letters, posters, reviews, and qualitative studies. Random effects meta‐analysis was performed. Heterogeneity was assessed using τ2 and I2 statistics. Potential bias was assessed using standard funnel plots. Asymmetry was evaluated by Egger's test. Leave‐one‐out analysis was performed for sensitivity analyses.ResultsThree eligible studies were found for LBW, seven for PTB, and four for SGA. The number of subjects ranged from 135 to 4889, and the prevalence of high job strain ranged from 6.64% to 33.9%. The pooled odds ratio and 95% confidence interval (CI) for LBW, PTB, and SGA were 1.23 (95% CI: 0.97, 1.56), 1.10 (95% CI: 1.00, 1.22), and 1.16 (95% CI: 0.97, 1.39) respectively, indicating modest associations. Heterogeneity for LBW and PTB may not be important but may be moderate for SGA. No publication bias was detected for LBW and PTB, but possible publication bias exists for SGA.ConclusionWe found a modest association between job strain and PTB. Since job strain is only one of the many aspects of an unhealthy work environment, interventions that improve working conditions more broadly are needed.

Published: September 2024

AbstractPosttranslational modifications (PTMs) greatly enhance the functional diversity of proteins, surpassing the number of gene‐encoded variations. One intriguing PTM is ADP‐ribosylation, which utilizes nicotinamide adenine dinucleotide (NAD+) as a substrate and is essential in cell signaling pathways regulating cellular responses. Here, we report the first cell‐permeable NAD+ analogs and demonstrate their utility for investigating cellular ADP‐ribosylation. Using a desthiobiotin‐labelled analog for affinity enrichment of proteins that are ADP‐ribosylated in living cells under oxidative stress, we identified protein targets associated with host‐virus interactions, DNA damage and repair, protein biosynthesis, and ribosome biogenesis. Most of these targets have been noted in various literature sources, highlighting the potential of our probes for cellular ADP‐ribosylome studies.

AbstractDefect engineering is an effective strategy for regulating the electrocatalysis of nanomaterials, yet it is seldom considered for modulating Pt‐based electrocatalysts for the oxygen reduction reaction (ORR). In this study, we designed Ni‐doped vacancy‐rich Pt nanoparticles anchored on nitrogen‐doped graphene (Vac‐NiPt NPs/NG) with a low Pt loading of 3.5 wt . % and a Ni/Pt ratio of 0.038 : 1. Physical characterizations confirmed the presence of abundant atomic‐scale vacancies in the Pt NPs induces long‐range lattice distortions, and the Ni dopant generates a ligand effect resulting in electronic transfer from Ni to Pt. Experimental results and theoretical calculations indicated that atomic‐scale vacancies mainly contributed the tolerance performances towards CO and CH3OH, the ligand effect derived from a tiny of Ni dopant accelerated the transformation from *O to *OH species, thereby improved the ORR activity without compromising the tolerance capabilities. Benefiting from the synergistic interplay between atomic‐scale vacancies and ligand effect, as‐prepared Vac‐NiPt NPs/NG exhibited improved ORR activity, sufficient tolerance capabilities, and excellent durability. This study offers a new avenue for modulating the electrocatalytic activity of metal‐based nanomaterials.

AbstractIntegration of living cells with extrinsic functional entities gives rise to bioaugmented nanobiohybrids, which hold tremendous potential across diverse fields such as cell therapy, biocatalysis, and cell robotics. This study presents a biocompatible method for incorporating multilayered functional liposomes onto the cell surface, creating extracellular artificial organelles or exorganelles. The introduction of various extrinsic functionalities to cells is achieved without comprising their viabilities. The integration of extrinsic enzymatic reactions is exemplified through the cascade reaction involving glucose oxidase and horseradish peroxidase. Furthermore, our protocol offers the design flexibility to customize liposome compositions, thereby providing effective cell modification. The versatility of the liposome‐based exorganelle approach establishes an advanced chemical tool, empowering cells with novel functionalities that surpass or are complementary to their innate capabilities.

AbstractSolid polymer electrolytes (SPEs) are crucial in the development of lithium metal batteries. Recently, metal–organic frameworks (MOFs) with open metal sites (OMSs) have shown promise as solid fillers to improve the performance of SPEs. However, the number of OMS‐containing MOFs is quite limited, comprising less than 5% of the total MOFs. When considering yield, cost, and processability, the commonly used OMS‐containing MOFs are no more than 10 types, causing great limitations. Herein, we reported a simple and universal methodology that converted OMS‐free MOFs to OMS‐rich quasi‐MOFs for developing high‐performance SPEs, and explored the underlying mechanism. The “OMS‐polymer” and “OMS‐ion” interactions were investigated in detail to elucidate the role of quasi‐MOFs on battery performance. It was found that quasi‐MOFs, functioning as ion sieves, can effectively regulate ion migration, thus promoting uniform Li deposition and enabling an ultra‐stable interface. As a result, the Li symmetric cell stably ran over 3000 h at 0.3 mA cm−2, while the full cell retained 85 % of its initial capacity after 1500 cycles at 1.0 C. Finally, universal testing was performed using other MOFs, confirming the generalizability and effectiveness of our design concept.

AbstractAlthough gapped grain boundaries have often been observed in bulk and nanosized materials, and their crucial roles in some physical and chemical processes have been confirmed, their acquisition at ultrasmall nanoscale presents a significant challenge. To date, they had not been reported in metal nanoparticles smaller than 2 nm owing to the difficulty in characterization and the high instability of grain boundary (GB) atoms. Herein, we have successfully developed a synthesis method for producing a novel chiral nanocluster Au78(TBBT)40 (TBBT=4‐tert‐butylphenylthiolate) with a 26‐atom gapped and rotated GB. This nanocluster was precisely characterized using single‐crystal X‐ray crystallography and mass spectrometry. Additionally, an offset atomic defect linked to the peripheral Au(TBBT)2 staple was found in the structure. Comparing it to similarly face‐centered cubic‐structured Au36(TBBT)24, Au44(TBBT)28, Au52(TBBT)32, Au92(TBBT)44, and ~5 nm nanocrystals, the bridging Au78(TBBT)40 nanocluster exhibited higher catalytic activity in the electroreduction of CO2 to CO. This enhanced activity was explained through density functional theory calculations and X‐ray photoelectron spectroscopy analysis, which highlight the impact of GBs and point defects on the surface properties of metal nanoclusters in balancing intermediate adsorption and product desorption.

AbstractUsing combinatory electrolyte blends represents an imperative avenue to achieve good magnesium (Mg)‐metal anode compatibility and commercial feasibility in fields of promising rechargeable Mg batteries. However, fundamental challenges of how to manipulate component modifier reactivity on molecule level still remain to be solved. Here, molecular structure design concepts towards seeking bromophenyl complex‐based component modifiers has been proposed according to implications of electron‐donating and/or electron‐withdrawing substituents on Br−C bond dissociation reactivity. Exceptional Mg electro‐plating/stripping properties (a stable cycle life of 250 days in Mg//Cu asymmetric cells) have been firstly achieved in a simple salt electrolyte with 1‐(3‐bromophenyl)‐N,N‐dimethylmethanamine (BPDMA) as optimal component modifier. Comprehensive analyses disclose the unique electrochemically‐active Br‐containing ion‐pairs formation, such as [(Mg2+)2(TFSI−)Br−]2+ and [(Mg2+)2(TFSI−)(Br−)(G2)2]2+, which results in the much thinner Br− containing and organic–inorganic mixed interphases on Mg‐metal anodes. Furthermore, conventional MgSO4‐based electrolytes and even calcium (Ca)‐ion electrolytes can also be revived by similar strategy, demonstrating its generality and superiority.

AbstractIn order to compare the effect of the monophenyl ring terephthalic acid (TPA) and biphenyl rings 4,4′‐oxybisbenzoic acid (OBBA) with ether bond on poly(butylene adipate) (PBA)‐based copolyesters properties, two copolyester series poly(butylene adipate‐co‐butylene terephthalate)s (PBATs) and poly(butylene adipate‐co‐butylene oxybisbenzoate)s (PBAOs) were synthesized, and comparatively investigated. All the synthesized copolyesters had satisfactory number‐average molecular weights in the range of 26,500–73,000 g/mol. For PBATs copolyesters, the crystalline structure gradually transitioned from the monoclinic crystal structure of poly(butylene adipate) to poly(butylene terephthalate) (PBT) with increasing TPA because of the crystalline segments transformation from butylene adipate to butylene terephthalate, while PBAO copolyesters progressively shifted from the crystalline structure of PBA to the amorphous structure of poly(butylene oxybisbenzoate) (PBO) as increasing content of OBBA. The incorporation of either TPA or OBBA comonomers with rigid cyclic structure into PBA chain noticeably increased the glass transition temperature (Tg). With the same monomer molar ratio, PBAOs because of incorporation of the bicyclic comonomers presented higher Tg (range from −24.2 to 49.5°C) than that of PBATs (range from −56.5 to 22.4°C). It was found that copolyesters with bicyclic and ether bond OBBA comonomers exhibited a better flexibility in property than that with monocyclic TPA comonomers.

AbstractThe Nickel‐based layered transition metal oxide cathode represented by NCM (LiNixCoyMnzO2, x+y+z=1) and NCA (LiNixCoyAlzO2, x+y+z=1) is widely used in the electric vehicle market due to its specific capacity and high working potential, in which Cobalt (Co) plays a huge role in improving the structural stability during the cycle. However, the limited supply of Co, due to its scarcity and the influence of geopolitics, poses a significant constraint on the further advancement of the Nickel‐based layered transition metal oxide cathode in the field of energy storage. In this paper, the mechanism of Co in the Nickel‐based layered transition metal oxides is reviewed, including its critical role for structural stability such as the inhibition of cationic mixing and the release of lattice oxygen et al. Subsequently, it outlines various strategies to enhance the performance of Co‐lean/free materials, such as ion doping, including single‐ion doping and multi‐ion co‐doping, and various surface coating strategies, so as to eliminate the adverse effects of Co loss on materials. Ultimately, this paper offers a glimpse into the promising future of Cobalt‐free strategies for high performance of Nickel‐based layered transition metal oxides.

Published: September 2024

AbstractLithium ion intercalation chemistry in graphite underpins commercial lithium‐ion batteries since 1991. In exploring the potential of cost‐effective graphite anodes in alternative battery systems, the conventional intercalation chemistry falls short for Na ions, which exhibited minimal capacity and thermodynamic unfavourability in sodium ion batteries (SIBs). The introduction of an alternative intercalation chemistry involving solvated‐Na‐ion co‐intercalation gives a rebirth to graphite anodes. The co‐intercalation chemistry allows appreciable Na ion storage capacities and extraordinary rate capabilities. The fundamental differences between intercalation and co‐intercalation chemistries have attracted extensive investigation over the past decade for high‐power SIBs. Herein, we focus on the state‐of‐the‐art advances on the co‐intercalation chemistry in the SIBs for the purpose of enriching insights into graphite intercalation chemistry. Following our introducing the thermodynamic features of co‐intercalation reactions, we will illuminate the electrochemical properties and mechanic issues of co‐intercalated graphite, finalized by the perspective challenges and potential resolutions.

AbstractThree dyes–diesters of monoimides of perylene‐3,4,9,10‐tetracarboxylic acid were synthesized in three‐stage process: esterification, hydrolysis, and monoimidation as potential fluorescent light‐stable colorants for high visibility safety wear. The structure of these compounds was confirmed by 1H nuclear magnetic resonance spectroscopy and mass spectrometry, and their spectroscopic and physicochemical properties were determined. Colorants were applied to dyeing polyester fibre and polystyrene and poly (methyl methacrylate) films. The light, wash, and rubbing fastness of the dyeings were determined, and chromaticity coordinates were measured and discussed.

AbstractThis study validates a stability‐indicating LC method for detecting organic impurities in the chlorzoxazone dosage form. Using a Waters X‐Select R HSS T3 analytical column, mobile phase of it was made by mixing of water, methanol, and glacial acetic acid in the ratio of 700:300:10 (v/v/v). The drug product and drug substance were subjected to the stress conditions such as acid, base, oxidation, heat, and photolysis as per the recommendations of the International Conference on Harmonization (Q2) methodology. The study revealed the susceptibility of 4‐chloro‐2‐aminophenol to alkaline environments, emphasizing peak homogeneity and stability. The method verification, per ICH guidelines and USP<1225>, established precision, specificity, linearity, accuracy, and robustness for quality control. The mean impurity recovery ranged from 95.5% to 105.2%, the correlation coefficient (r) was greater than 1.000, and the RSD values (n = 6) ranged from 0.6% to 5.1% across the LOQ–150% ranges. Full‐factorial design tested final method conditions, evaluating multiple parameters concurrently. Graphical optimization within the design space defined strong method requirements, ensuring consistent and reliable outcomes. The study develops and validates chlorzoxazone stability‐indicating methods, employing advanced statistical approaches like design of experiments and factorial design, with resilient conditions established through graphical optimization of the design space.

Published: September 2024

AbstractBackgroundIntracranial atherosclerotic stenosis (ICAS) is one of the most important independent risk factors for stroke that is closely related to the occurrence of cognitive impairment. The relationship between ICAS and vascular cognitive impairment (VCI) remains unclear. Cerebral hemodynamic changes are one of the main causes of cognitive impairment. Computed tomographic perfusion (CTP) imaging can quantitatively analyze cerebral blood perfusion and quantify cerebral hemodynamic changes. Previous research on the relationship between hypoperfusion induced by ICAS and cognitive impairment, as well as its underlying mechanisms, remains relatively insufficient. This study is dedicated to elucidating the characteristics and potential mechanisms of cognitive impairment in ICAS patients with abnormal perfusion, utilizing CTP imaging as our primary investigative tool.MethodsThis study recruited 82 patients who suffer from non‐disabling ischemic stroke (IS group) and 28 healthy controls. All participants underwent comprehensive neuropsychological assessments both collectively and individually, in addition to CTP imaging. Within the patient group, we further categorized individuals into two subgroups: the ischemic penumbra group (IP, N = 28) and the benign oligemia group (BO, N = 54), based on CTP parameters—Tmax. The correlations between cognitive function and abnormal perfusion were explored.ResultsThe cognitive function, including the overall cognitive, memory, attention, executive functions, and language, was significantly impaired in the IS group compared with that in the control group. Further, there are statistical differences in the stroop color–word test‐dot (Stroop‐D) and Montreal Cognitive Assessment (MoCA) sub‐items (memory + language) between the BO and IP groups. In the BO group, the score of Stroop‐D is lower, and the MoCA sub‐items are higher than the IP group. There is no correlation between CTP parameters and cognitive function.ConclusionCognitive function is significantly impaired in patients with ICAS, which is related to cerebral perfusion. Executive, memory, and language function were better preserved in ICAS patients without IP. Hence, this study posits that managing hypoperfusion induced by ICAS may play a pivotal role in the development of VCI.
