Interfacial Engineeringof Carbene-FunctionalizedZIF-90 Porous Liquid-like Dispersion-Based Mixed Matrix Membranesfor Enhanced Ethanol Recovery via Pervaporation

Abstract Mixed matrix membranes (MMMs) are promising for overcoming the permeability–selectivity limitations of polymeric membranes, yet their performance is often restricted by filler aggregation and interfacial defects at high loadings. Here, we introduce ZIF-90 in a porous liq...

The impact of environmental, social, and governance uncertainty and economic growth on green energy management in the United States

Green energy is no longer merely an environmental priority for the United States; it has become a strategic pathway for sustainable development shaped by environmental, social, and governance uncertainty (ESGU) and economic growth (ECG). Against this background, this study examin...

Enhanced Hybrid Retrieval-Augmented Model for Question Answering in High-Sensitivity Domains

Arabic question-answering systems in high-sensitivity domains require not only accurate retrieval but also reliable evidence grounding and effective hallucination mitigation, as incorrect or unsupported responses may have serious consequences. Existing retrieval and generation ap...

Nonlinear primary resonance and dynamic stability in parametrically excited self-sustaining curved SWCNTs subjected to a thermal and magnetic loads

Abstract This research conducts a systematic examination of the nonlinear dynamic behaviour exhibited by curved single-walled carbon nanotubes (CSWCNTs) under parametric excitation while embedded in a nonlinear viscoelastic medium. The investigation employs nonlocal Euler–Bernoul...

Colorectal cancer incidence and clinicopathological patterns in Saudi Arabia, 2013–2023: A national registry analysis with exploratory estimation of attributable risk factor burden

ABSTRACT Background: Colorectal cancer (CRC) is the most commonly diagnosed cancer among Saudi males and a leading cause of cancer mortality in Saudi Arabia. Systematic characterization of its incidence and clinicopathological patterns is needed to inform national screening and p...

A Greener Approach towardYnones via Visible-Light-InducedOxidation of Propargyl Alcohols under Aqueous-Aerobic Conditions

Abstract A simple and convenient approach involving visible-light-induced, TBHP-mediated oxidation of propargyl alcohols to ynone in aqueous media has been developed. This photoinduced protocol was conducted under an aerobic-aqueous medium using Eosin Y as a photosensitizer. A di...

Synthesis and evaluation of fluorinated chromene-pyridone as a dual-acting agent against Alzheimer's disease and cancer: biological assessment and computational modelling

The global challenge of neurodegenerative diseases and cancer necessitates new multifunctional therapeutics. We designed and synthesised novel chromene-hydrazone derivatives as multitarget ligands. Structures were confirmed spectroscopically and by X-ray crystallography, with dat...

Self-medication among higher education students: prevalence, risk factors, and health information-seeking behaviours

The WHO estimates that more than two-thirds of university students engage in this practice. This study aims to determine the prevalence, knowledge, attitudes, and practices related to self-medication, along with the determinants that influence these behaviors, among higher educat...
