Application of NEXRAD precipitation data for assessing the implications of low development practices in an ungauged basin
Authors: Aryal Abhiru , Kalra Ajay 
Published: August 2023

AbstractHydrologic analysis in watersheds lacking rain gauge stations has been a challenge and even those with stations that do not contain the required amount of data create problems in model verification. So, the study integrates the Next Generation Weather RadarIII precipitation data and the Personal Computer Storm Water Management Model (PCSWMM) for evaluating the model's effectiveness. The study further integrates 100‐year return period precipitation intensity and PCSWMM to generate a one‐dimensional flood risk zone map, which shows the major sub‐catchments under risk zones. Based on the identification of risk zones from PCSWMM, three different low‐impact developments (LIDs), street plants, infiltration trenches, and green roofs are applied independently and uniformly to compare the decrease in flow. Thereafter, the prioritized list of critical sub‐catchments from hydraulic modeling is compared with the compromise programming method, an approach for studying the decrement in flow by increasing LID application (infiltration trench) in the first five critical sub‐catchments, suggesting planners and researchers identify the most critical sub‐catchments and develop future potential strategies.

Published: August 2023

AbstractA classifier may be limited by its conditional misclassification rates more than its overall misclassification rate. In the case that one or more of the conditional misclassification rates are high, a neutral zone may be introduced to decrease and possibly balance the misclassification rates. In this paper, a neutral zone is incorporated into a three‐class classifier with its region determined by controlling conditional misclassification rates. The neutral zone classifier is illustrated with a text mining application that classifies written comments associated with student evaluations of teaching.
Trade openness helps move towards carbon neutrality—Insight from 114 countries
Authors: Wang Qiang , Wang Lili , Li Rongrong 
Published: August 2023

AbstractIn order to better understand the impact of trade openness and foreign direct investment (FDI) on carbon neutrality (economic growth without increasing carbon emissions), linear fully modified ordinary least squares model and non‐linear panel threshold regression model are applied to explore the impact of trade openness and FDI on economic growth and carbon emissions in 114 countries. The results of the Tapio decoupling model showed that the decoupling between economic growth and carbon emissions is an M‐shaped from 2002‐2015, and a strong decoupling exists between them after 2015. The results from the linear model showed that FDI promotes both economic growth and carbon emissions. Trade openness promotes economic growth, but curbs the increase in carbon emissions. In other word, trade openness contributes to economic without increasing carbon emissions, which is conducive to achieving carbon neutrality. The results of the non‐linear model showed that when FDI crosses the threshold, the effect of FDI on economic growth first promotes and then inhibits and then promotes, the effect of FDI on promoting carbon emissions first increases and then decreases. When trade openness crosses the threshold, the promotion effect of trade openness on economic growth increases, while the inhibitory effect of trade openness on carbon emissions decreases. Finally, the policy implications are proposed.

Authors: Takeuchi Yuki , Ohkubo Takahiro 
Published: August 2023

AbstractMetal oxides have the excellent functions including high thermal stability, electrical properties, catalytic performance, and adsorption properties of acid gases such as CO2 via the acid‐base interactions. However, they suffer from low reserves, porosity control, and low adsorption efficiency per weight compared with lightweight materials including carbon and silica. To solve these issues, various methods for supporting metal oxides on porous carriers, such as decomposition‐precipitation and impregnation, have been investigated, but controlling the formation of metal oxide on clay nanosheets remains as a challenge. Herein, we developed a soft‐template method for supporting metal oxide (CuOx) nanoparticles on activated clay nanosheets. The intercalation of polyethyleneimine (PEI)−Cu2+ complexes between the layers of clay nanosheets followed by calcination to construct CuOx and remove the PEI templates afforded CuOx/clay nanocomposites. The constructed CuOx/clay nanocomposites had the close porosity to that of clay. Tuning the Cu2+/PEI ratio in PEI−Cu2+ complex allowed to control CuOx states (loadings, particle sizes, etc.). Tuning of the supporting conditions allowed constructing a structure suitable for CO2 uptake. These findings will contribute to the development of the material science of metal oxide nanoparticles and their hybrid materials in diverse fields including CO2 adsorbents, energy devices, and catalysts.

Authors: Wei Yuli , Yang Wu , Guo Hao 
Published: August 2023

AbstractAt present, applications of covalent organic frameworks (COFs), a class of novel crystalline porous materials fabricated by organic structural blocks only containing light elements such as C, H, N, O and B through strong covalent bonds, in electrochemical sensing have entered a period of rapid development and showed great potential in various analytical fields such as environmental analysis, food analysis, pharmaceutical analysis, biological and clinical analysis owing to their unique advantages including regular porosity, large specific surface area, periodical ordered structure, extended π‐conjugated system, abundant functional groups and outstanding thermal and chemical stability. But there are still many concerns that need to be urgently solved for further electrochemical sensing application including improvement of electric conductivity and enhancement of selectivity. Limited by poor conductivity and low recognition ability of primitive COFs, they always need to be further functionalized. To further promote the development of COFs‐based electrochemical sensing technology, here, we summarize and review the recent advances on construction of two‐dimensional functional COFs materials for electrochemical sensing applications and related sensing device setups in detail, including design strategies, preparation methods, modification considerations, sensing principles and analytical applications, and tentatively propose development prospects and outlooks in future.

Published: August 2023

AbstractBiocompatible hydrogels of polyvinylpyrrolidone (PVP) with tannic acid (TA) in the weight ratios of 1 : 0.70 (70 %)–1 : 0.60 (60 %) were prepared and loaded with the antifungal drug, nystatin (NYS). The hydrogel is expected to exhibit a two‐fold (anti‐bacterial and anti‐fungal) characteristics. Infrared spectroscopy (IR), viscometry and differential scanning calorimetry (DSC) were used to investigate interactions between PVP and TA. In vitro release kinetics of NYS in simulated body fluid (SBF) and sweat (SS) were studied using ultra‐violet spectroscopy (UV) and high‐performance liquid chromatography (HPLC). An increase in the glass transition temperature (Tg) of PVP accompanied with changes observed in the OH stretching, C=O and the C−O−C regions in the IR spectrum in dried PVP/TA hydrogel suggested physical crosslinking. The swelling of the hydrogels in distilled deionized water (DDW), SBF and SS decreased with increasing TA concentration and showed pH sensitivity. TA release followed the Korsmeyer‐Peppas kinetic model regardless of swelling media while NYS followed the Korsmeyer‐Peppas and Hixson‐Crowell cube root law in SS and SBF respectively. TA was active against Escherichia coli and Staphylococcus aureus while NYS against Candida albicans. A topical patch was prepared by adhering the drug loaded PVP/TA hydrogel onto silicone strips.

Published: August 2023

AbstractNanotechnology is a critical tool to manipulate the sophisticated behavior of biological structures and has provided new research fields. Liquid–liquid phase‐separated (LLPS) droplets gather attention as basic reaction fields in a living cell. Droplets play critical roles in regulating protein behavior, including enzyme compartmentalization, stress response, and disease pathogenesis. The dynamic manipulation of LLPS droplet formation/deformation has become a crucial target in nanobiotechnology. However, the development of nanodevices specifically designed for this purpose remains a challenge. Therefore, this study presents butterfly‐shaped gold nanobutterflies (GNBs) as novel nanodevices for manipulating LLPS droplet dynamics. The growth process of the GNBs is analyzed via time‐lapse electroscopic imaging, time‐lapse spectroscopy, and additives assays. Interestingly, GNBs demonstrate the ability to induce LLPS droplet formation in systems such as adenosine triphosphate/poly‐l‐lysine and human immunoglobulin G, whereas spherical and rod‐shaped gold nanoparticles exhibit no such capability. This indicates that the GNB concave surface interacts with the droplet precursors facilitating the LLPS droplet formation. Near‐infrared‐laser irradiation applied to GNBs enables on‐demand deformation of the droplets through localized heat effects. GNB regulates the enzymatic reaction of lysozymes. The innovative design of GNBs presents a promising strategy for manipulating LLPS dynamics and offers exciting prospects for future research.

AbstractThe development of innovative and efficient Fe‐N‐C catalysts is crucial for the widespread application of zinc‐air batteries (ZABs), where the inherent oxygen reduction reaction (ORR) activity of Fe single‐atom sites needs to be optimized to meet the practical application. Herein, a three‐dimensional (3D) hollow hierarchical porous electrocatalyst (ZIF8@FePMPDA‐920) rich in asymmetric Fe‐N4‐OH moieties as the single atomic sites is reported. The Fe center is in a penta‐coordinated geometry with four N atoms and one O atom to form Fe‐N4‐OH configuration. Compared to conventional Fe‐N4 configuration, this unique structure can weaken the adsorption of intermediates by reducing the electron density of the Fe center for oxygen binding, which decreases the energy barrier of the rate‐determining steps (RDS) to accelerate the ORR and oxygen evolution reaction (OER) processes for ZABs. The rechargeable liquid ZABs (LZABs) equipped with ZIF8@FePMPDA‐920 display a high power density of 123.11 mW cm−2 and a long cycle life (300 h). The relevant flexible all‐solid‐state ZABs (FASSZABs) also display outstanding foldability and cyclical stability. This work provides a new perspective for the structural design of single‐atom catalysts in the energy conversion and storage areas.

Published: August 2023

Despite great advances in understanding the biological behaviors of chiral materials, the effect of chirality‐configured nanoparticles on tissue regeneration‐related biological processes remains poorly understood. Herein, the chirality of MoS2 quantum dots (QDs) is tailored by functionalization with l‐/d‐penicillamine, and the profound chiral effects of MoS2 QDs on cellular activities, angiogenesis, and tissue regeneration are thoroughly investigated. Specifically, d‐MoS2 QDs show a positive effect in promoting the growth, proliferation, and migration of human umbilical vein endothelial cells. The expression of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), and fibroblast growth factor (FGF) in d‐MoS2 QDs group is substantially up‐regulated, resulting in enhanced tube formation activity. This distinct phenomenon is largely due to the higher internalization efficiency of d‐MoS2 QDs than l‐MoS2 QDs and chirality‐dependent nano‐bio interactions. In vivo angiogenic assay shows the expression level of angiogenic markers in newly‐formed skin tissues of d‐MoS2 QDs group is higher than that in l‐MoS2 QDs group, leading to an accelerated re‐epithelialization and improved skin regeneration. The findings of chirality‐dependent angiogenesis activity of MoS2 QDs provide new insights into the biological activity of MoS2 nanomaterials, which also opens up a new path to the rational design of chiral nanomaterials for tissue regeneration application.

AbstractThe structural coexistence of dual rigid and mobile sublattices in superionic Argyrodites yields ultralow lattice thermal conductivity along with decent electrical and ionic conductivities and therefore attracts intense interest for batteries, fuel cells, and thermoelectric applications. However, a comprehensive understanding of their underlying lattice and diffusive dynamics in terms of the interplay between phonons and mobile ions is missing. Herein, inelastic neutron scattering is employed to unravel that phonon softening on heating to Tc ≈ 350 K triggers fast Ag diffusion in the canonical superionic Argyrodite Ag8GeSe6. Ab initio molecular dynamics simulations reproduce the experimental neutron scattering signals and identify the partially ultrafast Ag diffusion with a large diffusion coefficient of 10−4 cm−2 s−1. The study illustrates the microscopic interconnection between soft phonons and mobile ions and provides a paradigm for an intertwined interaction of the lattice and diffusive dynamics in superionic materials.

Published: August 2023

AbstractBrassinin, a phytochemical in cruciferous vegetables, is an indoleamine 2,3‐dioxygenase inhibitor and possesses a therapeutic opportunity in cancer immunotherapy. Here, we have developed and validated a novel, specific, and rapid bioanalytical method in rat plasma that is unavailable in the literature for preclinical studies. The method development involved single‐step protein precipitation as an extraction method using acetonitrile with an absolute and relative mean recovery of 79.32% and 93.59%, respectively. The method is accurate and precise over the linearity range of 1.0–50.0 μg/mL with a retention time of 5.3 and 3.5 min of brassinin and telmisartan, an internal standard. The intra‐day and inter‐day precision of the method expressed as a %coefficient of variation, ranging from 0.03% to 2.82% and 0.39% to 5.82%, whereas intra‐day and inter‐day accuracy ranged from 99.75% to 103.40% and 99.76% to 104.25%, respectively. The high‐performance liquid chromatography bioanalytical method was successfully validated as per Food and Drug Administration guidelines, and it can be applied in routine bioanalysis and pharmacokinetic studies.

Published: August 2023

AbstractThe present study aims to characterize the physicochemical, morphological, functional, thermal properties and in vitro digestibility of Amaranthus paniculatus flour (APF) and A. paniculatus starch (APS). A significant difference (p ≤ 0.05) is observed in the chemical composition of A. paniculatus flour and starch; the amylose content of the starch (3.91%) is found to be significantly higher (p ≤ 0.05) than flour (2.35%). Morphology of APS reveals that the starch granules are polygonal, have a smooth surface, and have no fissures. A. paniculatus flour and starch exhibit A‐type crystallinity; however, the relative crystallinity of APS (15.75%) is significantly higher (p ≤ 0.05) than flour (12.76%). The functional properties, including solubility, water and oil absorption capacity of APF are significantly higher (p ≤ 0.05) than APS. The enthalpy of gelatinization (ΔH) of APS is found to be significantly higher (p ≤ 0.05) than APF. A. paniculatus starch has a significantly higher (p ≤ 0.05) amount of rapid digestible starch (RDS) than flour, however, the flour of A. paniculatus has significantly higher (p ≤ 0.05) resistant starch (RS) and slowly digestible starch (SDS). The study reveals that A. paniculatus flour and starch are significantly different from each other and can be used in various food and non‐food industries due to their physicochemical, functional, and structural properties.
New damage evolution law in plastic damage models for fiber‐reinforced cementitious composites

Published: August 2023

AbstractNowadays, fiber‐reinforced cement‐based composites (FRCC) can develop ductile behavior with high toughness when the matrix, fibers, and interface are optimally designed. These materials are promising solutions for constructing more resilient structures. In this context, the widespread use in large‐scale applications requires reliable models to predict the performance of FRCC structures. Usually, the studies on numerical modeling of FRCC apply the damage laws developed for quasi‐brittle concrete, making damage increase faster than really occurs in the presence of fibers. Therefore, the present paper proposes a new damage evolution model for FRCC based on energy dissipation concepts. It is assumed that the dissipated energy contributes fully to the evolution of the scalar damage and plastic strain variables, which is a technical advance from the previous works. The damage evolution is obtained with experimental envelopes of uniaxial stress–strain tests and the focal point from loading–unloading cycles. The results showed that the model accurately predicted experimental results using the damage‐plasticity framework. Furthermore, there are no empirical constants in the proposal, which means that it can be applied to any class of FRCC. An application regarding damage evaluation near a load transfer device in jointed plain cementitious pavements is presented. The damage distribution reveals that using FRCC materials has induced smaller damage values when compared with using conventional concrete. Consequently, cracking is reduced in such zones, increasing the structural life of the pavement.

Published: August 2023

AbstractPatagonia (Argentina and Chile) harbors the highest Saccharomyces eubayanus genomic diversity and its widest predominance in natural environments. In this work, S. eubayanus was isolated for the first time from a fermentative environment. This species was found dominating both a traditional apple chicha fermentation as well as feral apple trees in the Andean region of Aluminé (Argentina). S. eubayanus was the only Saccharomyces species found in the isolation substrates, although it coexisted with other non‐Saccharomyces species. The absence of strong fermentative competitors of the Saccharomyces genus (like Saccharomyces uvarum or Saccharomyces cerevisiae) in the feral apples could promote the development and implantation of S. eubayanus in a spontaneous apple must fermentation. Phylogeographic analyses revealed a high intraspecific diversity in S. eubayanus, enabling the characterization of strains belonging to the genomic subpopulations PA1, PA2, and PB1 according to the sequences obtained for the intFR gene region. This result evidence that the studied sampling area represents a natural habitat for the species. Being a novel finding, studying the causes that allowed this species to prosper in a fermentative environment becomes essential. Hence, the physiological profile of the new isolates, including their ability to grow at different temperature, nitrogen, and ethanol concentrations was evaluated in comparison with a set of S. eubayanus strains previously isolated from natural environment and representing different genomic subpopulations. Greater physiological diversity was evidenced when strains isolated from both natural and fermentative environments were analyzed overall. Furthermore, no direct relationship between genomic population and physiological behavior was observed; on the opposite, strains appeared to exhibit similar behavior, primarily grouped by isolation origin.
