Abstract Electrical and electronic devices face significant challenges in heat management due to their compact size and high heat flux, which negatively impact performance and reliability. Conventional cooling methods, such as forced air cooling, often struggle to transfer heat efficiently. In contrast, thermoelectric coolers (TECs) provide an innovative active cooling solution to meet growing thermal management demands. In this research, a refrigerant based on mono ethylene glycol and distilled water was used instead of using gases, in addition to using thermoelectric cooling units instead of using a compressor in traditional refrigeration systems. This study evaluates the… More > Graphic Abstract

Abstract Addressing the persistent challenge of shale hydration and swelling in water-based drilling fluids (WBDFs), this study developed a smart thermo-responsive shale inhibitor, Hyperbranched Polyethyleneimine-Propylene Oxide-N-isopropylacrylamide (HPN). It was synthesized by grafting hyperbranched polyethyleneimine (HPEI) with propylene oxide (PO) and N-isopropylacrylamide (NIPAM), creating a synergistic hydration barrier through hydrophobic association and temperature-triggered pore plugging. Structural characterization by Fourier-Transform Infrared (FTIR) spectroscopy and gel permeation chromatography (GPC) confirmed the successful formation of the HPN terpolymer, revealing a unique “cationic–nonionic” amphiphilic architecture with temperature-responsive properties. Performance evaluation demonstrated that HPN significantly outperforms conventional inhibitors, including potassium chloride (KCl),… More >

Abstract In this study Fe doped SnO₂-SnS₂ (FS) and Fe doped SnO₂-SnS₂-polypyrrole (FS-PPY) were synthesized and studied for the methylene blue (MB) egrdation under UV light. The morphological and structural characterizations were carried out by FTIR, SEM-EDX, XRD and XPS. It has been found that FS-PPy degrade methylene blue upto 98 % under optimized conditions as pH =3, dye concentration = 10 ppm, oxidant dose = 2 mM. The Langmuir-Hinshelwood kinetics model fitted well. The optimization was studied using response surface methodology. Scavengers study was carried out to find the active species. Reusability of photocatalyst was evaluated More >

Abstract This study focuses on the development of zinc oxide (ZnO)/zinc sulfide (ZnS) core-shell structures on flexible polyethylene terephthalate (PET) substrates for enhanced light sensing. PET offers high elasticity, optical transparency, and chemical resistance, making it ideal for wearable optoelectronics. By optimizing the vulcanization process, a uniform ZnS shell is formed on the exposed regions of ZnO nanorods (NRs), significantly enhancing ZnO-based sensor’s sensitivity to visible light, especially red light (peak wavelength at 630 nm). Structural and spectral analyses confirm the successful formation of the ZnO/ZnS heterostructure, improved charge separation, and broadened light response. To improve More >

Abstract Electrospinning has gained significant importance across various fields, including biomedicine, filtration, and packaging due to the control it provides over the properties of the resulting materials, such as fiber diameter and membrane thickness. Chitosan is a biopolymer that can be utilized with both natural and synthetic copolymers, owing to its therapeutic potential, biocompatibility, and biodegradability. However, producing electrospun chitosan is challenging due to its high solution viscosity, which often results in the formation of beads instead of uniform fibers. To address this issue, the spinnability of chitosan is significantly enhanced, and the production of continuous More >

Abstract Acer paxii belongs to the evergreen species of Acer, but it exhibits a unique feature of reddish leaves in fall in subtropical regions. Although the association of AP2/ERF transcription factors with color change has been well-documented in prior research, molecular investigations focusing on AP2/ERF remain notably lacking in Acer paxii. This research focuses on performing an extensive genome-wide investigation to identify and characterize the AP2/ERF gene family in Acer paxii. As a result, 123 ApAP2/ERFs were obtained. Phylogenetic analyses categorized the ApAP2/ERF family members into 15 subfamilies. The evolutionary traits of the ApAP2/ERFs were investigated by analyzing their… More >

Abstract In the production processes of modern industry, accurate assessment of the system’s health state and traceability non-optimal factors are key to ensuring “safe, stable, long-term, full load and optimal” operation of the production process. The benzene-to-ethylene ratio control system is a complex system based on an MPC-PID double-layer architecture. Taking into consideration the interaction between levels, coupling between loops and conditions of incomplete operation data, this paper proposes a health assessment method for the dual-layer control system by comprehensively utilizing deep learning technology. Firstly, according to the results of the pre-assessment of the system layers… More >

Abstract Background: U2AF homology motif kinase 1 (UHMK1) has been associated with RNA processing and protein phosphorylation, thereby influencing tumor progression. The study aimed to explore its regulatory mechanisms and biological functions in human prostate cancer (PCa). Methods: In this study, we systematically evaluated the expression and prognostic significance of UHMK1 in public databases, followed by validation through immunohistochemistry (IHC) in PCa specimens. Both gain-of-function and loss-of-function experiments were conducted to elucidate the role of UHMK1 in vitro and in vivo. Additionally, a series of molecular and biochemical assays were performed to investigate the regulatory mechanisms underlying UHMK1… More >

Abstract Power cables are important pieces of equipment for energy transmission, but achieving a good balance between flame retardancy and mechanical properties of cable sheaths remains a challenge. In this work, a novel intumescent flame retardant (IFR) system containing silicone-containing macromolecular charring agent (Si-MCA) and ammonium polyphosphate (APP) was designed to synergistically improve the flame retardancy and mechanical properties of ethylene-butyl acrylate copolymer (EBA) composites. The optimal mass ratio of APP/Si-MCA was 3/1 in EBA composites (EBA/APP-Si-31), corresponding to the best flame retardancy with 31.2% of limited oxygen index (LOI), V-0 rating in UL-94 vertical burning More > Graphic Abstract

Abstract With the widespread use of polyethylene (PE) materials in gas pipelines, the problem related to the aging of these pipes has attracted increasing attention. Especially under complex environmental conditions involving temperature, humidity, and pressure changes, PE pipes are prone to oxidative degradation, which adversely affects their performance and service life. This study investigates the aging behavior of PE pipes used for gas transport under the combined effects of temperature (ranging from 80°C to 110°C) and pressure (0, 0.1, 0.2, and 0.3 MPa). By assessing the characteristics and thermal stability of the aged pipes, relevant efforts… More >
