Published: July 2024

AbstractSemiconductor‐assisted photocatalytic treatment is among the most effective methods for eliminating persistent contaminants from industrial wastewater. This study presents a hydrothermal approach for the preparation of Cobalt Telluride (CoTe) nanosheets for the degradation of aniline blue dye under visible light irradiation. The synthesized catalyst was characterized using various techniques, including X‐ray diffraction (XRD), field emission scanning electron microscopy (FESEM), energy dispersive X‐ray spectroscopy (EDX), Fourier transform infrared (FTIR) spectroscopy, RAMAN spectroscopy, high‐Resolution transmission electron microscopy (HRTEM), and X‐ray photoelectron spectroscopy (XPS). Tauc's model was used to determine the optical band gap. The key operating parameters, such as the amount of CoTe, initial aniline blue (AB) concentration, and contact time, have been optimized to achieve the highest AB degradation percentage. Under visible light, 98 % of dye degradation occurred within 60 minutes. The degradation process was further assessed using total organic carbon (TOC) measurements. Free‐radical capture experiments were conducted to identify the role of radical species in the photocatalytic process. The photocatalytic process revealed that the equilibrium data aligns well with the Langmuir‐Hinshelwood kinetic model. A rate constant of 0.03486 min−1 was obtained. The photocatalyst demonstrated excellent recyclability, maintaining efficiency and structural integrity over five cycles. The photocatalytic experiment results also have been confirmed by a density functional theory (DFT) calculation.

AbstractMetal‐Organic Frameworks (MOFs) represent a highly promising class of materials with diverse applications, particularly as catalytic materials. However, their synthesis typically yields powders available only at laboratory‐scale quantities, usually in the gram range or less. This study addresses the challenge of testing limited amounts of MOF catalysts for demanding applications, such as multiphase gas‐liquid‐solid reactions in flow, utilizing a packed‐bed microreactor. Specifically, we investigate the performance of a nanoparticle (NP) ‐immobilized Pd@UiO‐66 MOF catalyst in the selective semi‐hydrogenation of phenylacetylene to styrene, serving as a model reaction. Maintaining the Taylor flow regime upstream of the catalyst bed was crucial to ensure reproducible and reliable experimental results. We conducted 88 experiments at varying liquid flow rates, temperatures ranging from 15 to 45 °C, and relative pressures spanning 0.28 to 8 bar. Styrene selectivity within the range of 80–92.3 % was achieved at phenylacetylene conversions below 20 %. Notably, the optimal condition for styrene selectivity (70 %) was attained at 98.9 % phenylacetylene conversion under the lowest H2 pressure and highest temperature, demonstrating the significance of low H2 concentration for achieving optimal styrene selectivity. Remarkably, the catalyst exhibited stable activity and selectivity over a 20 h testing period, indicating its robust performance under prolonged reaction conditions. This study demonstrates the potential of the proposed catalyst testing system as a rapid and efficient approach for early‐stage exploration studies, particularly when limited quantities of catalyst, typically in the gram scale or less, are available.

Published: July 2024

AbstractPreparing asymmetric pervaporation membranes is a kind of promising method to enhance pervaporation membrane flux. Hydrophobic PVDF polymer can be used to prepare asymmetric pervaporation membranes, but its separation factor is relatively low. In this work, to improve the performance of PVDF membrane pervaporation, PDMS polymer was added to the PVDF membrane, and asymmetric PDMS/PVDF permeable membranes were prepared by the non‐solvent induced phase separation (NIPS) method. The effects of mass ratios of PDMS to PVDF on the membrane structures and the membrane properties were characterized by SEM, XRD, FTIR, TGA, water contact angle and mechanical strength. The results showed that the ratios of the PDMS: PVDF affect its phase‐separation behavior. As the addition of PDMS increased, the finger‐like pores on the membrane section gradually became longer, the upper surface changed from less porous to porous structure, and the lower surface structure changed from interconnected flocculent structure to porous, and the best structure of the blend membrane was achieved when the PDMS: PVDF mass ratio was 1 : 5. Therefore, the membrane had the best separation performance in separating 15 wt. % ethanol aqueous solution with a permeate total flux of 273.65 g/(m2 h) and a separation factor of 9.09 when the mass ratio of PDMS: PVDF was 1 : 5.

AbstractGraphene, a remarkable material known for its exceptional properties, can be efficiently produced through environmentally friendly methods using renewable resources and eco‐friendly solvents. Recent studies have highlighted the potential of leaf extracts as effective reducing and stabilizing agents in converting graphene oxide (GO) to graphene. This paper presents a green and cost‐effective approach for the effective deposition of silver nanoparticles (Ag NPs) onto the reduced graphene oxide (RGO) nanosheets. The process involves the co‐reduction of GO and AgNO3 in water using Moringa olifera leaf extract, resulting in the formation of a nanocomposite termed reduced graphene oxide‐silver (Ag‐RGO). The formation of RGO and Ag NP is confirmed through UV‐visible spectroscopy, XRD, and Raman spectroscopy techniques. TEM images revealed the morphology of the nanocomposite, depicting 2‐dimensional graphene sheets adorned with Ag NPs. FT‐IR analysis confirmed the removal of oxygenated functional groups from GO, indicating graphene formation. The synthesized Ag‐RGO nanocomposite exhibited significant catalytic, antioxidant, and electrochemical properties. This study underscores the utilization of natural ingredients as sustainable alternatives for producing multifunctional graphene‐silver nanocomposites.

AbstractG‐quadruplex DNA (GQ‐DNA) represents one of the most significant non‐canonical nucleic acid configurations. GQ‐DNA producing sequences are found in different important genomic areas, including the promoter islands of numerous oncogenes and human telomere regions. Therefore, GQ‐DNA is a key target for anticancer medicines. GQ‐DNA has a highly variable structure, it is critical to develop ligand molecules that selectively target certain quadruplex sequences. Natural products such as pyridocarbazole alkaloids have grown interest for healthcare and medicinal values and they considered as a valuable source of innovative anticancer medicines among the chemical compounds. In this investigation, we have synthesised and characterized pyrido[2,3‐c]carbazole derivative (PCAD) through NMR and IR spectra and explore the interactions between PCAD and Pu24T GQ (promoter region), h‐TELO GQ (telomere region) and duplex DNA by employing several multi‐spectroscopic analytical techniques. We have found that PCAD preferentially interacts with Pu24T GQ DNA as compared to other DNA sequences. These findings highlights PCAD as an appealing option for targeting the Pu24T promoter region and consequently acting as an anti‐cancer drug. This study also highlights the potential for developing drugs to understand the molecular aspects of GQ DNA recognition and signaling, paving the way for future research on GQ biology.

Published: July 2024

AbstractStable, efficient, and economical bifunctional electrocatalysts for oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) are needed for rechargeable Zn–air batteries. In this study, a directional electron transfer pathway is exploited in a spatial heterojunction of CoyNix@Fe─N─C heterogeneous catalyst for effective bifunctional electrolysis (OER/ORR). Thereinto, the Co/Ni alloy is strongly coupled to the Fe─N─C support through Co/Ni─N bonds. DFT calculations and experimental findings confirm that Co/Ni─N bonds play a bridging role in the directional electron transfer from Co/Ni alloy to the Fe─N─C support, increasing the content of pyridinic nitrogen in the ORR‐active support. In addition, the discovered directional electron transfer mechanism enhances both the ORR/OER activity and the durability of the catalyst. The Co0.66Ni0.34@Fe─N─C with the optimal Ni/Co ratio exhibits satisfying bifunctional electrocatalytic performance, requiring an ORR half‐wave potential of 0.90 V and an OER overpotential of 317 mV at 10 mA cm−2 in alkaline electrolytes. The assembled rechargeable zinc–air batteries (ZABs) incorporating Co0.66Ni0.34@Fe─N─C cathode exhibits a charge–discharge voltage gap comparable to the Pt/C||IrO2 assembly and high robustness for over 60 h at 20 mA cm−2.

Published: July 2024

AbstractExtending the layer spacing of the (001) planes to regulate the mobility of Zn2+ is widely adopted to optimize the performance of VOPO4·2H2O cathode for zinc‐ion batteries. However, the unique function originating from other planes is often neglected. Herein, an effective in situ conversion methodology is proposed for the synthesis of the (200) oriented growth of vertical VOPO4·2H2O nanosheets with oxygen vacancies (VOd‐VOPO4). Theoretical simulation and ex situ characterizations collaboratively demonstrate that the richly exposed (200) plane with tetragonal channels can offer quick pathways for in‐layer and cross‐layer migration of Zn2+, exhibiting enhanced transfer kinetics with improved reversible capacity. Meanwhile, efficient electron migration in VOd‐VOPO4 is guaranteed by the introduction of oxygen vacancies. Thus, the as‐prepared VOd‐VOPO4 harvests exceptional discharge capacity, impressive rate capability, and remarkable long‐cycle stability at high mass loading. Notably, the VOd‐VOPO4 electrode (15 mg cm−2) provides a capacity of 213.5 mAh g−1 with an ultrahigh areal capacity of 3.02 mAh cm−2 at 0.1 A g−1, showing great potential for applications. This study highlights the orientated growth strategy for facilitating ion storage and migration, offering novel perspectives on the development of high‐performance electrodes and beyond.

Mapping Institutional Resilience: Locating Regulatory and Growth Frameworks in Central Asia
Authors: Khudaykulov Adham 
Published: July 2024

AbstractThis chapter aims to investigate the nexus of state regulation and economic performance from an institutional resilience-building perspective. Specially, I examine the case of the post-Soviet transition economies of Central Asia since gaining independence in the early 1990s. This region’s economic landscape has undergone profound structural changes following the dissolution and implosion of the former Soviet Union. Following a brief economic recession in the early ‘90 s, caused by the rapid disruption to production and economic linkages within the former Soviet Union, the regional economy has quickly recovered and experienced steady economic growth in recent decades. In this chapter, I examine the economic development observed in the region through the exploration of a regulatory regime capable of withstanding various political and economic challenges. In doing so, this study contributes to resilience thinking in economics by examining the robustness of the established regulatory regimes in Central Asian countries in responding and adjusting to the disruptions caused by external and internal factors and ensuring sustainable economic growth.
Taxation in the Digital Economy in Uzbekistan
Authors: Pulatov Alisher 
Published: July 2024

AbstractDigital economy taxation plays a crucial role in the modern globalised world, where digital businesses and transactions are increasingly prominent. As digitalisation continues transforming various aspects of society and the economy, governments face challenges of effectively regulating and taxing digital activities. This chapter focuses on Uzbekistan, exploring the importance of regulating digital businesses and implementing taxation. Here, I aim to understand the significance of digital economy taxation and its implications for Uzbekistan's legal system, business environment, investment climate, societal change, and governance. Specifically, I delve into identifying non-resident businesses subject to value-added tax (VAT) and the associated challenges faced by tax authorities. I discuss the complexities of determining who should pay taxes and the difficulties in establishing the necessary nexuses to enforce taxation on digital service providers. Furthermore, I highlight the limitations of existing methods used to identify VAT-liable businesses, including the limited technical capacity and access to financial data. From my analysis, I outline recommendations for improving digital economy taxation, and recommend developing enforcement mechanisms, exchanging information between non-resident companies and tax authorities, utilising technology, and considering thresholds to support startups and small businesses. These recommendations should foster a fair and efficient tax system supporting the evolving digital landscape and promoting economic growth.
Multiple Agents Involved in the Localization of Our Lady of La Vang: From a Mythic Figure to the Mother of Vietnam
Authors: Duong Van Bien 
Published: July 2024

AbstractOur Lady of La Vang is a version of the Virgin Mary that was first worshipped over a century ago at a place called La Vang in what is now Quảng Trị Province. Today, she is sometimes called the “Mother of Vietnam,” is represented wearing Vietnamese robes and is said to symbolize a supposed essential element of Vietnamese culture, the reverence of women. In other words, Our Lady of La Vang has been fully “localized.” However, the ways in which this happened are complex, and in this chapter, we discuss how scholars have explained the localization of Our Lady of La Vang, and Catholicism in Vietnam more generally, and then proceed to make our own analysis of this issue. In the end, we demonstrate that there have been multiple agents and agendas involved in the localization of Our Lady of La Vang. Further, these agents extend beyond Vietnam and include the Catholic church as well as members of the Vietnamese diaspora.
Feature engineering and parameter tuning: improving phenomic prediction ability in multi-environmental durum wheat breeding trials

Abstract
Key Message
Optimized phenomic selection in durum wheat uses near-infrared spectra, feature engineering and parameter tuning. Our study reports improvements in predictive ability and emphasizes customized preprocessing for different traits and models.

Abstract
The success of plant breeding programs depends on efficient selection decisions. Phenomic selection has been proposed as a tool to predict phenotype performance based on near-infrared spectra (NIRS) to support selection decisions. In this study, we test the performance of phenomic selection in multi-environmental trials from our durum wheat breeding program for three breeding scenarios and use feature engineering as well as parameter tuning to improve the phenomic prediction ability. In addition, we investigate the influence of genotype and environment on the phenomic prediction ability for agronomic and quality traits. Preprocessing, based on a grid search over the Savitzky–Golay filter parameters based on 756,000 genotype best linear unbiased estimate (BLUE) computations, improved the phenomic prediction ability by up to 1500% (0.02–0.3). Furthermore, we show that preprocessing should be optimized depending on the dataset, trait, and model used for prediction. The phenomic prediction scenarios in our durum breeding program resulted in low-to-moderate prediction abilities with the highest and most stable prediction results when predicting new genotypes in the same environment as used for model training. This is consistent with the finding that NIRS capture both the genotype and genotype-by-environment $$(G\times E)$$

Published: July 2024

AbstractThe main objective of this study is to evaluate residual stresses in AISI 316L and 18Ni Maraging 300 functionally graded materials with continuous variation of composition within a single layer using the contour method. The manufacture of this kind of layer-level continuous functionally graded materials by employing a Powder Bed Fusion-Laser Beam system utilizing a blade/roller-based powder spreading technique has only been recently devised and a proper residual stress analysis is still required. In fact, as the mechanical properties of additively manufactured samples are significantly influenced by the direction of construction, the same holds true for the direction along which the compositional variation is made. Furthermore, in this study, the impact of solution annealing and aging heat treatment, which are necessary for enhancing the mechanical properties of martensitic steel, on residual stresses was explored. Additionally, the effect of adopting material-differentiated process parameters was investigated. The results indicated that each specimen displayed areas of tensile stress concentration on the upper and lower surfaces, balanced by compression in the center. The application of heat treatment led to a decrease in the maximum tensile stress of 8% and provided a uniform and significant stress reduction within the maraging steel. Finally, the implementation of material-specific process parameters for the three composition zones in conjunction with the heat treatment resulted in a reduction in the maximum residual stress of 35% and also a significantly lower residual stress field throughout the specimen.
