In this work, assembled ZnO/ZnCo2O4 heterostructure nanosheets (ZnO/ZCO) were successfully synthesized through a rapid one-step microwave-assisted hydrothermal method. The ZnO/ZnCo2O4 sample features an ordered assembly of nanocrystals with a size of 30 nm forming two dimensional (2D) nanosheets, and ZnO-ZnCo2O4 heterojunctions are uniformly distributed. The physicochemical properties of ZnO/ZCO heterostructures were systematically studied by combining experiments and density functional theory (DFT) calculation. The heterojunction configuration of ZnO and ZnCo2O4 produced an interfacial charge redistribution and strong electronic interaction, resulting in the enhanced electrocatalytic performance towards ofloxacin (OFL). Consequently, the ZnO/ZnCo2O4 heterostructure nanosheet-based electrochemical sensor possessed an outstanding sensing performance in the detection of OFL with a high electrochemical sensitivity of 1.97 µA µM−1 cm−2. In addition, the proposed sensor was successfully applied for the detection of OFL in tap and lake water with recovery rates of 97.0–99.2%. The study demonstrates the potential of spinel oxide-based electrochemical sensors for rapid and cost-effective detection of antibiotic residues, providing an effective solution for water quality safety monitoring.

Abstract. Nguyen TV, Kasim M, Anggraini T, Doan LN, Duong NV. 2025. Resilience of wild and cultivated bitter melon (Momordica charantia) under deficit irrigation in Vietnam. Biodiversitas 26: 5248-5257. Water scarcity increasingly constrains vegetable production in tropical regions, requiring adaptive strategies such as deficit irrigation and the use of resilient genetic resources. This study evaluated the physiological and agronomic responses of two Momordica charantia accessions—designated as the wild type (TCCS VP-BT08/16) and the cultivated type (TCCS VP-BT01/14)—under three irrigation regimes (80 %, 65 %, and 50 % of field capacity, FC) in a split-plot field experiment conducted during the 2024–2025 dry season in Vietnam. Growth traits, SPAD chlorophyll values, and cumulative dry fruit yield were assessed using ANOVA and Duncan's multiple range test (P < 0.05). Irrigation significantly influenced all measured traits (P ? 0.001). The cultivated type showed strong early vigor under full irrigation but declined rapidly after ~90 days under water stress, whereas the wild type maintained stable growth, branching, leaf production, and SPAD values across irrigation levels through 120 days. Dry fruit yield was sustained at 65% FC in both accessions (~185 g plant-¹ wild, ~178 g plant-1 cultivated) without significant reduction from full irrigation, while severe deficit (50% FC) caused moderate yield decline in the wild (~22%) and substantial losses in the cultivated type (~50%). These findings indicate that maintaining soil moisture at 65% FC can sustain bitter melon yield under dry-season conditions and highlight the superior drought resilience of the wild bitter melon as a valuable genetic resource for breeding climate-resilient cultivars.

Abstract Plastic waste from end-of-life (EOL) fishing nets is a significant contributor to marine pollution. Recycling these nets has attracted increasing attention, particularly in coastal countries such as Vietnam. However, recycled materials often exhibit reduced properties compared to virgin materials due to degradation. Blending recycled and virgin polymers provides a simple solution to obtain materials with properties close to virgin ones, thereby reducing the demand for natural resource extraction. In this study, EOL trawling nets were collected, cleaned, shredded, and extruded into recycled granulates (RGs), which were compared with virgin granulates (VGs) and a 1:1 blend (R-VGs). Characterization was performed using FTIR, DSC, MFI, and tensile testing. Results confirm that the nets are made of high-density polyethylene (HDPE). RGs showed slightly lower yield stress (20.94 MPa) than VGs (21.59 MPa), while R-VGs reached 21.50 MPa, closely matching virgin properties. The mechanical performance of RGs was sufficient for filament production in 3D printing, demonstrating a feasible approach toward sustainable circular economy applications.

Bài báo trình bày cấu hình mạch nghịch lưu 1 pha tăng áp cầu H được điều khiển với giải thuật có khả năng giảm tổn hao chuyển mạch trên các khoá công suất. Cấu hình kết hợp bộ chuyển đổi DC-DC tăng áp ba bậc và bộ nghịch lưu 1 pha cầu H. Khác với giải thuật thông thường, điện áp sau bộ chuyển đổi DC-DC tăng áp được duy trì ở mức hằng số, bài báo đề xuất giải thuật điều khiển điện áp DC-link cấp cho phía nghịch lưu thay đổi được trong hai chế độ. Chế độ giảm áp, điện áp DC đầu vào lớn hơn điện áp đầu ra, khi này chỉ các khoá ở phía nghịch lưu hoạt động tạo điện áp đầu ra. Và ngược lại, ở chế độ tăng áp, điện áp DC đầu vào thấp hơn điện áp đầu ra, các khoá bán dẫn của bộ chuyển đổi DC-DC tăng áp điều khiển điện áp DC-link bằng với điện áp đầu ra. Từ đó giảm được số lần chuyển mạch cũng như điện áp đặt trên các khoá bán dẫn. Từ đó cải thiện hiệu suất so với giải thuật thông thường. Ngoài ra, việc sử dụng tụ film thay thế cho các tụ hoá làm cho bộ nghịch lưu có hiệu suất và độ tin cậy cao hơn. Để kiểm chứng lợi thế của việc giảm tổn hao chuyển mạch, các kết quả mô phỏng phân tích tổn hao công suất được thực hiện bằng phần mền PSIM.

Building Information Modeling (BIM) is a transformative technology driving digital innovation in the construction industry. Beyond a 3D design tool, BIM serves as a comprehensive data integration platform that facilitates seamless collaboration among stakeholders throughout the entire project lifecycle - from design and construction to operation. This article provides an overview of BIM, exploring its applications, benefits, challenges, and future development trends. Currently, BIM is extensively utilized in architecture, civil engineering, MEP (mechanical, electrical, and plumbing), and infrastructure management. Its advanced simulation and analytical capabilities help minimize design errors, optimize costs, accelerate project timelines, and enhance construction quality. However, challenges such as high initial investment, workforce training demands, and integration with legacy systems remain significant barriers to widespread adoption. Despite these obstacles, ongoing technological advancements and supportive policies are solidifying BIM’s role as an industry standard. Looking ahead, BIM is expected to integrate with Artificial Intelligence (AI), Virtual Reality (VR), Augmented Reality (AR), and the Internet of Things (IoT), fostering a digital ecosystem that enhances efficiency and sustainability in construction.

Purpose This study aims to explore key questions within the context of Asian countries: How do artificial intelligence (AI) and blockchain adoption in accounting influence enterprise risk management and environmental, social and governance (ESG) performance? What role does enterprise risk management have as a mediator in this relationship? In addition, how does environmental uncertainty shape the interplay between AI and blockchain adoption in accounting, enterprise risk management and ESG performance? Design/methodology/approach The authors collected data from Thomson Reuters Eikon Datastream, initially targeting the 20 Asian countries with the highest gross domestic product (GDP) per capita. Using stringent selection criteria, the research sample included 22,212 firms from these countries: Bahrain, China, Hong Kong, Indonesia, Israel, Japan, Jordan, Kazakhstan, South Korea, Kuwait, Lebanon, Malaysia, Oman, Qatar, Saudi Arabia, Singapore, Sri Lanka, Thailand, the United Arab Emirates and Vietnam. After a rigorous screening process, the final sample comprised 1,742 firms, representing 17,420 firm-year observations over the 2014–2023 period. This paper applied maximum likelihood structural equation modeling to analyze the data. Findings The findings reveal that both AI and blockchain adoption in accounting, along with enterprise risk management, positively impact ESG performance in the Asian context. Enterprise risk management serves as a mediating factor between AI and blockchain adoption in accounting and ESG performance. In addition, environmental uncertainty significantly moderates the relationships between AI and blockchain adoption in accounting and enterprise risk management, as well as between enterprise risk management and ESG performance. Practical implications This study uncovers the interplay between internal factors – such as AI and blockchain adoption in accounting and enterprise risk management – and external factors, notably environmental uncertainty, in fostering sustainable value for Asian firms. Internal factors enable firms to integrate ESG considerations into their operations, facilitating risk mitigation and enhancing ESG performance. Meanwhile, heightened environmental uncertainty drives the adoption of sustainable practices. Consequently, Asian Governments should prioritize the development of regions characterized by high environmental uncertainty to advance national sustainable development goals and encourage responsible business practices. Originality/value This study contributes to the existing literature by uncovering the combined effects of internal and external factors on ESG performance, offering empirical evidence from Asian countries with high GDP per capita. Specifically, it underscores the efficacy of AI and blockchain adoption in accounting and enterprise risk management, as well as the moderating role of environmental uncertainty, within the Asian context.

Background: Patients diagnosed with chronic kidney disease (CKD) have a heightened risk of developing masked uncontrolled hypertension (MUCH), leading to hypertension-induced organ damage. This study aimed to estimate the prevalence and characteristics of MUCH and to investigate risk factors of left ventricular hypertrophy (LVH) in those with CKD. Methods: A retrospective study was conducted on data from 178 patients diagnosed with CKD and having controlled office blood pressure at Nhan Dan Gia Dinh Hospital between October 2018 and June 2019. These participants underwent 24-hour ambulatory blood pressure monitoring (ABPM) using the SunTech Oscar 2 device. Subsequently, echocardiography was performed to assess for the presence of LVH. Results: The prevalence of MUCH was 48.9%. Notably, all patients with MUCH demonstrated elevated nighttime blood pressure. LVH was more prevalent in the MUCH group when compared to those with controlled hypertension (55.2% and 38.5%, respectively). MUCH and CKD staging 4-5 were independent risk factors of LVH with ORs 1.97 (95% CI, 1.03-3.85) and 2.58 (95% CI, 1.16-5.94), respectively. Conclusions: We recommend routinely using ABPM to detect MUCH in CKD patients even with controlled office hypertension. Screening for LVH is necessary in those with MUCH.
