Authors: Singh Neha , Malik Ankur , Sethi Paras , Mondal Prakash Chandra 
Published: July 2024

AbstractInterfacial electron transport in multicomponent systems plays a crucial role in controlling electrical conductivity. Organic–inorganic heterostructures electronic devices where all the entities are covalently bonded to each other can reduce interfacial electrical resistance, thus suitable for low‐power consumption electronic operations. Programmed heterostructures of covalently bonded interfaces between ITO‐ethynylbenzene (EB) and EB‐zinc ferrite (ZF) nanoparticles, a programmed structure showing 67 978‐fold enhancement of electrical current as compared to pristine NPs‐based two terminal devices are created. An electrochemical approach is adopted to prepare nearly π‐conjugated EB oligomer films of thickness ≈26 nm on ITO‐electrode on which ZF NPs are chemically attached. A “flip‐chip” method is employed to combine two EB‐ZnFe2O4 NPs‐ITO to probe electrical conductivity and charge conduction mechanism. The EB‐ZnFe2O4 NPs exhibit strong electronic coupling at ITO‐EB and EB‐NPs with an energy barrier of 0.13 eV between the ITO Fermi level and the LUMO of EB‐ZF NPs for efficient charge transport. Both the DC and AC‐based electrical measurements manifest a low resistance at ITO‐EB and EB‐ZF NPs, revealing enhanced electrical current at ± 1.5 V. The programmed heterostructure devices can meet a strategy to create well‐controlled molecular layers for electronic applications toward miniaturized components that shorten charge carrier distance, and interfacial resistance.

AbstractThrombus causes a serious condition characterized by the formation of blood clots in blood vessels or heart, potentially leading to life‐threatening emergencies. Photothermal therapy (PTT) serves as a treatment for thrombosis that provides noninvasive thrombus dissolution and fewer bleeding side effects. However, the high temperatures generated by PTT can exacerbate vascular inflammation and promote thrombus recurrence. In this study, a photothermal hydrogen sulfide (H2S) nanogenerator (PSA@ADT‐OH) is constructed using a perylene‐cored photothermal agent (PSA) coassembled with a H2S donor ADT‐OH. The system PSA@ADT‐OH demonstrates outstanding targeting and accumulation efficiency against blood flow shear forces. It also provides sustained H2S release at thrombus sites, contributing to antiplatelet aggregation, reactive oxygen species clearance, and vascular healing. This approach opens up new possibilities for advanced thrombus treatment.

AbstractGold tailings is formed as an industrial waste during gold mining and processing. The aim of the current study is to use it to prepare foamed concrete as subgrade filler. The effect of wet density (600, 700 and 800 kg/m3) and tailings content (15, 30, 45 and 60 wt%) on fluidity, compressive strength, elastic modulus, drying shrinkage, freeze–thaw resistance, hydration heat and pore structure were investigated. It was found that incorporating tailings into foamed concrete decreases the compressive strength as tailings adversely affected the pore structure, resulting in increased porosity, enlarged and connected pores, and reduced sphericity. To meet the requirement of subgrade filler, the tailings content was limited to 30 wt% when the designed wet density was 600 kg/m3 and it was 45 wt% when the wet density increased to 700 and 800 kg/m3. Nevertheless, increasing the tailings content effectively reduced the drying shrinkage and early age hydration heat which are favorable for massive foamed concrete construction. Besides, the incorporation of gold tailings is helpful to the freeze–thaw resistance of 600 and 700 kg/m3 foamed concrete for application in seasonal frozen areas.

Published: July 2024

AbstractCement production is responsible for 5%–7% of global CO2 emissions, highlighting the need for sustainable alternatives like geopolymer composite (GCOMP) to meet the growing demand for concrete. This study investigates the mechanical, microstructural, and thermal properties of GCOMP by incorporating nano‐alumina (n‐alumina) and MSF (MSF). The n‐alumina content was varied at 1%, 2%, and 3% by weight of the mix, while the MSF content remained fixed at 0.5% by weight. Thermal characterization was conducted up to 800°C. The performance of GCOMP blends with n‐alumina was compared to a control blend consisting of only 0.5% MSF. Various mechanical properties were evaluated for all GCOMP blends. Microstructural and mineralogical characteristics were analyzed using scanning electron microscopy (SEM), X‐ray diffraction (XRD), and Fourier‐transform infrared spectroscopy (FTIR). Thermogravimetric and differential thermal analysis were performed up to 800°C for the thermal analysis of the GCOMP mix. The results indicate that the optimal mechanical properties were achieved with 2% n‐alumina (compressive and flexural strength increased by 35.65% and 77.7%, respectively). Additionally, the incorporation of n‐alumina improves the interfacial zones and results in a denser structure. GCOMP mortars portrayed a mass loss between 25°C and 250°C, with a marginal mass loss occurring between 250°C and 715°C. No mass loss was observed between 715°C and 800°C. The MSF‐reinforced GCOMP mortars experienced an ultimate mass loss of approximately 12%, with the MSF showing negligible influence. The addition of n‐alumina particles to MSF‐reinforced GCOMP resulted in the development of stronger samples characterized by the presence of C–S–H, calcium aluminate oxide hydroxide, and quartz.

AbstractThis paper investigates the effects of pozzolanic substitutions for ordinary Portland cement (OPC) with silica fume (SF) and metakaolin (MK) on the mechanical and toughness performances of steel fiber reinforced concrete (SFRC). Initially, a reference concrete mix with a water‐to‐binder ratio of 0.4 is blended with different volume fractions of steel fibers with varying geometry: crimped steel (CS) and straight steel (SS), both individually and in combination, to examine their mechanical properties. In the subsequent phase, the study investigates the impact of combining macro‐ and microsteel fibers on flexural toughness, to determine potential synergy for suitable combinations. Also, the possible influence of pozzolans in the variation of flexural toughness of hybrid steel fiber reinforced concrete (Hy‐SFRC) was evaluated. Hybridization of steel fibers was found effective in improving the workability of the concrete mix up to 11%. SFRC mixes containing pozzolans exhibited a significant enhancement in compressive strength, modulus of rupture, and modulus of elasticity compared to non‐pozzolanic SFRC. The hybrid combination of CS 1.5% and SS 0.5% was considered the best in terms of mechanical properties. Additionally, the results of synergy assessment showed that hybridization of steel fibers in the pozzolanic concrete mix was particularly effective in the post‐cracking stages with a positive 14% compared to a negative 8% in the pre‐cracking stage. The pozzolanic addition improved the flexural toughness of Hy‐SFRC to about 10%–20%. Blending of SF and MK in Hy‐SFRC was found effective in enhancing the toughness mechanism of concrete compared to Hy‐SFRC mixes containing binary SF and MK, indicating a stronger bond between the fibers and the matrix resulting from the pore refinement and hydration products developed at the interface. Hy‐SFRC containing a ternary pozzolanic mix of SF 10% and MK 10% gave the best results in flexural toughness, and the corresponding synergy values were found to be the maximum. The results were consistent with the morphology analysis, which revealed an increase in hydration products at the interface between the aggregate and concrete matrix, as well as between the steel fiber and concrete matrix, due to the ternary blending of SF and MK.

ABSTRACTPyriproxyfen (PPF) is an insecticide used in agriculture, which is approved for use in drinking water tanks for human consumption. However, some studies indicate that it may act as an endocrine disruptor and affect nontarget organisms. This study aimed to evaluate the effects of PPF on reproduction and general health status in female mice exposed from pre‐puberty to adulthood. In the first experiment, females were treated by gavage from postnatal day (PND) 23 to (PND) 75 and were distributed into three experimental groups: control (vehicle), PPF 0.1 mg/kg, and PPF 1 mg/kg. Female mice were assessed for the age of puberty onset, body mass, water and food consumption, and the estrous cycle. On PDN 75, a subgroup was euthanized, when vital and reproductive organs were collected and weighed. The thyroid, ovary, and uterus were evaluated for histomorphometry. The other subgroup was assessed in relation to reproductive performance and fetal parameters. In a second experiment, the uterotrophic assay was performed with juvenile females (PND 18) using doses of 0.01, 0.1, or 1 mg/kg of PPF. PPF treatment reduced thyroid mass and increased liver mass. Furthermore, there was an increase in ovarian interstitial tissue and, in the uterus, a decrease in the thickness of the endometrial stroma with reduced content of collagen fibers. There was also a reduction of 30% in pregnancy rate in the treated groups and an increase in the frequency of fetal death. This study suggests that, based on this experimental model, the insecticide may pose a reproductive risk for females chronically exposed to the substance from the pre‐pubertal period until adulthood. These results raise concerns about prolonged exposure of women to the same compound.

Published: July 2024

AbstractSoySNP50K and SoySNP6K are commonly used for soybean (Glycine max) genotyping. The SoySNP50K assay has been used to genetically analyze the entire USDA Soybean Germplasm Collection, while the SoySNP6K assay, containing a subset of 6000 single‐nucleotide polymorphisms (SNPs) from SoySNP50K, has been used for quantitative trait loci mapping of different traits. To meet the needs for genomic selection, selection of parents for crosses, and characterization of breeding populations, especially early selection of ideal offspring from thousands of lines, we developed two assays, SoySNP3K and SoySNP1K, containing 3072 and 1252 SNPs, respectively, based on SoySNP50K and SoySNP6K mark sets. These two assays also contained the trait markers reported or contributed by soybean breeders. The SNPs in the SoySNP3K are a subset from SoySNP6K, while the SNPs in the SoySNP1K are a subset from SoySNP3K. These SNPs were chosen to reduce the SNP number in the large linkage blocks while capturing as much of the haplotype diversity as possible. They are highly polymorphic and of high quality. The mean minor allele frequencies of the SNPs in the southern and northern US elites were 0.25 and 0.27 for SoySNP3K, respectively, and 0.29 and 0.33 for SoySNP1K. The selected SNPs are a valuable source for developing targeted amplicon sequencing assay or beadchip assay in soybean. SoySNP3K and SoySNP1K assays are commercialized by Illumina Inc. and AgriPlex Genomics, respectively. Together with SoySNP50K and SoySNP6K, a series of nested assays with different marker densities will serve as additional low‐cost genomic tools for genetic, genomic, and breeding research.
Water throughout the green energy transition: Hydrosocial dimensions of coal, natural gas, and lithium
Authors: Cousins Joshua J. , Cantor Alida , Turley Bethani 
Published: July 2024

AbstractEnergy transitions are reshaping hydrosocial relations. How they will be reshaped, however, depends on location and water's material relationship to other resources and industrial activities embedded within energy transitions. To highlight this, we focus on three different resources—coal, natural gas, and lithium—to signal how the water–energy nexus will be reworked in a transition away from fossil fuels. We examine the water–coal nexus as an example of a resource relationship that is transitioning out, or that is being moved away from in the green energy transition. Natural gas represents the “bridge fuel” used through the transition. Lithium illustrates a resource inside the green transition, as it is a fundamental material for green technologies in the transition to a low‐carbon future. Coal, natural gas, and lithium each have their own material impacts to water resources that stem from their industrial lifecycle and different implications for communities shaped by coal, natural gas, and lithium activities. To explore this, we review each of these resources' connection to water, their legal and regulatory dimensions, and their impact on communities and water justice. We argue that the energy transition is also a hydrosocial transition that will create uneven water‐related benefits and burdens. To maximize sustainability and equity, efforts to decarbonize energy systems must examine the localized, place‐based hydrosocial relations that differentially affect communities.This article is categorized under:

Exact analysis of hydromagnetic non‐Gray optically thick heat absorbing fluid with nonlinear parabolic ramped conditions
Authors: Bordoloi Rajdeep , Ahmed Nazibuddin , Chamuah Kalyan , Chamkha Ali J. 
Published: July 2024

AbstractThe article presents a solution to a complex problem involving a transient MHD‐free convective chemically reactive flow. The flow involves a viscous incompressible electrically conducting non‐Gray optically thick fluid moving past a semi‐infinite vertical plate that has suddenly started but is temporarily accelerated. The plate has nonlinear parabolic ramped conditions, and the flow is exposed to thermal radiation, heat absorbing sink, and diffusion‐thermo effect. For the current study, the model fluid being used is moist air. The governing equations are obtained using the Laplace transform technique with the help of the Heaviside step function. This study is the first to consider parabolic ramped motion, temperature and concentration simultaneously. Effects of the pertinent parameters on the Sherwood number and Nusselt number are visualized using 3D surface plotting. Findings of the problem manifest that concentration, temperature, and velocity profiles in case of ramped conditions are less than in isothermal conditions. The rate of heat transfer of mercury is less than oxygen, air, water, and ethanol at a room temperature of 22°C–25°C. The ramped plate has the tendency to augment the heat transfer rate. The present study is of great interest in numerous fields of industry and machine‐building applications.

Published: July 2024

AbstractThis research venture comprehends a theoretical examination of non‐Newtonian fluid flowing peristaltic via an elliptical channel. Furthermore, the Prandtl fluid method for this elliptic duct problem is thoroughly considered. This mathematical inquiry adopts a non‐Newtonian Prandtl fluid model. A polynomial methodology is used to analyze partial differential equations that appear in nondimensional form and deliver an exact analytical solution for the temperature and velocity profile. This study is the first to utilize a novel order polynomial of degree eight having eleven constants to precisely solve the temperature equation for Prandtl fluid flow via an elliptic domain. A comprehensive graphical analysis is also provided to understand the mathematical conclusions fully. The graphs of the velocity profiles clearly show that the non‐Newtonian effects are more potent along the minor axis of the elliptical duct. The streamlined graphs accentuating the trapping phenomenon show specific closed contours close to the boundary wall of the peristaltic duct.
International Organisations and Norm Diffusion: The Case of UNODC in Central Asia
Authors: Genç H. Deniz 
Published: July 2024

AbstractThe political landscape of Central Asia experienced a profound and irreversible transformation following the dissolution of the Soviet Union. While common trends, such as shifting from planned to market economies and attempts at democratisation, were observed, the distinctive context of each Central Asian state played a unique role in shaping their individual transitions. This process has been further accelerated since the early 2000s with the increasing presence and influence of various actors, including states, multinational companies, and nongovernment and international organisations, across the region. Within this evolving landscape, international organisations have emerged as norm entrepreneurs, playing significant roles in diffusing norms within Central Asia. Whilst actively involved in the region, UNODC’s specific activities, projects, and mechanisms via which it disseminates norms on issues within its mandate in Central Asia remain unexplored. This chapter addresses this gap and seeks to answer the following questions: How does UNODC foster international norms and standards in response to transnational challenges? Why is UNODC’s involvement crucial in facilitating norm diffusion within Central Asia? This study also addresses potential contestation from the Shanghai Cooperation Organisation (SCO) against UNODC’s norm diffusion and reflects upon evolving global governance dynamics and the boundaries of norm diffusion in the Central Asian region.
Huỳnh Thị Bảo Hòa (1896–1982): A Woman Who Wrote to Change Vietnamese Society
Authors: Nguyen Phuong Ngoc 
Published: July 2024

AbstractFor centuries, women in Vietnam had to respect the three obediences of Confucian morality. However, at the beginning of the twentieth century, a radical change took place: women went to school, wrote in the press, gave lectures, published novels and books, led associations, and campaigned for the status of women. In this chapter, we examine the life of a woman who lived during this time. Mrs. Huỳnh Thị Bảo Hòa, born in 1896, is known for her activities on behalf of women, as well as for her account of a trip to the mountains near Đà Nẵng, her essay on the kingdom of Champa and her novel telling the story of a Vietnamese man who was enlisted to fight in France during the First World War and who married a French woman. Through an examination of her biography, we will gain a better understanding of the life of an educated woman in Vietnam at the beginning of the twentieth century. We will then analyze her novel, The Western Beauty, published in Saigon in 1927 to gain a deeper sense of Mrs. Huỳnh Thị Bảo Hòa’s views on the place of Vietnamese women in colonial Vietnam.
An Educational Regime of Truth for Social Reform in Late Colonial Vietnam: The Journalistic Art of the Possible in Phụ nữ tân văn’s “Travel Stories” and “Letters for You”
Authors: Phùng Thanh , Vũ Đăng Minh 
Published: July 2024

AbstractThis chapter examines the presentation of the woman question in Vietnamese journalism in the 1920s–1930s. It spotlights how two columns in the paper Women’s News (Phụ nữ tân văn), “Travel Stories” (Du ký), and “Letters for You” (Thơ cho bạn), fabricated, in a journalistic manner, internationally minded and socially engaged woman figures for a modern Vietnam through authorial modalities of openness and female impersonation. Based on an analysis of the columns and their context, the chapter identifies what can be called an educational regime of truth for social reform in late colonial Vietnam in these journalistic works.

Abstract
We present resummed predictions at next-to-leading logarithmic accuracy matched to the exact next-to-leading order results for a set of classical event-shape observables in hadronic Higgs decays, i.e., for the channels H → gg and H → $$ b\overline{b} $$

Differences in the QCD radiation pattern of gluon- and quark-initiated final states are imprinted in the event-shape distributions, offering separation power for the two decay channels. In particular, we show that ungroomed event shapes in H → gg decays develop a considerably harder spectrum than in H → $$ b\overline{b} $$

Monge Surfaces. Generation, Discretisation and Application in Architecture
Authors: Gonzalez‑Quintial Francisco , Martín‑Pastor Andrés 
Published: July 2024

AbstractThis paper describes a revision of so-called Monge surfaces through using digital graphic tools, based on the synthetic conception exposed by Gaspard Monge in the 18th and 19th centuries, through their geometric relation with polar surface. As a starting point, we propose a graphical system that integrally solves the generation of these kind of surfaces, their rationalization and discretization, with the objective of their specific application in architecture. The geometric system described allows the generation of a type of surface in which the pair of curves -generatrix and directrix- give rise to the network of principal lines of curvature (LCP) of the final surface. In this way, we propose a process that follows a bottom-up generative system based on Monge surfaces, which offers wide possibilities of formal exploration, while imposing geometrical-constructive properties that are very useful in fabrication and assembly processes.
