Development and investigation of a NiO/ZnO@PPy-modified glassy carbon electrode for electrochemical sensing of metronidazole in environmental samples: Experimental and DFT studies

Metronidazole (MTZ) is widely prescribed as an antimicrobial drug, and its extensive use in animal farming has led to its accumulation in the environment, posing significant risks to human health and the environment. In this study, nickel and zinc oxide (NiO/ZnO) composite materi...

Improving Meteorological Drought Forecasting Through a CPO ‐Tuned VMD ‐Liquid Neural Network

ABSTRACT This paper introduces a novel hybrid model for one‐month‐ahead meteorological drought forecasting. The proposed approach employs the Crested Porcupine Optimizer (CPO) to adaptively tune the key parameters of Variational Mode Decomposition (VMD). This optimization step ef...

A Spectral Tau Algorithm Using Shifted Convolved Fibonacci Polynomials for Singular Functional Models

In this paper, for some second-order singular functional differential equations (SOSFDEs), a tau-type spectral technique is built using non-origin-symmetric polynomials called shifted convolved Fibonacci polynomials as the approximation basis. Derivative formulae, integral identi...

A multilevel perspective on university student mental health: a systematic review of determinants and implications for social inclusion

Purpose This study aims to synthesise determinants of university student mental health through a multilevel framework and examine their implications for social inclusion. Design/methodology/approach Following preferred reporting items for systematic reviews and meta-analyses 2020...

Optimized Wavy Thermal Radiative Analysis of Electrochemically Ternary Hybrid Nanomaterials Affected by an Induced Magnetic Force: An ANN‐Based Levenberg–Marquardt Backpropagation Approach

ABSTRACT This study is motivated by the growing demand for highly efficient thermal management fluids in modern energy systems, microelectronics and industrial heat flow processes, where conventional fluids fail to meet rising performance requirements. To address these limitation...

Numerical and machine learning framework for strategic fin design to accelerate phase change material melting in advanced enclosures

The melting behavior of phase change materials (PCMs) is numerically investigated in rectangular, trapezoidal, and heptahedral enclosures equipped with identical V-shaped fins, under coupled parametric variations. The investigated parameters include PCM type (RT-25 to RT-38), fin...

Nanoparticle-Mediated Waste Valorization: Transforming Heavy Metal Pollutants into Efficient Electrocatalysts for Methanol Oxidation

This study demonstrates a waste-to-catalyst strategy in which nickel ferrite (NFO) first removes Cu(II), Co(II), and Cd(II) from aqueous solutions, and the resulting metal-loaded ferrites are subsequently employed as non-noble-metal electrodes for alkaline methanol oxidation. Pri...

Seismic vulnerability and sustainable retrofit strategies for traditional masonry heritage buildings in Oman

Traditional masonry buildings constitute an important part of Oman’s architectural heritage; however, their seismic performance has received limited systematic attention despite the country’s exposure to regional and local seismic hazards. This study presents a qualitative assess...

Design and Optimization of Smart-Grid-Connected Microgrids for EV Charging Stations Integrating Net Energy Metering and Demand Response

The widespread adoption of EVs is expected to intensify peak demand, stress distribution networks, and increase carbon emissions if traditional grid-based charging models continue. Therefore, this study proposes a smart-grid-connected microgrid (MG) architecture for EV charging s...

Synergistic engineering of mixing A-site cations and oxygen vacancies to boost optical, electrochemical, and dielectric properties of Ag0.5Na0.5NbO3−δ

Ag 0.5 Na 0.5 NbO 3−δ lead-free perovskite was synthesized using a conventional solid-state method. X-ray diffraction (XRD) confirmed an orthorhombic (Pbcm) Ag 0.5 Na 0.5 NbO 3−δ perovskite phase with a small monoclinic (P2 1 /n) NaAgNb 4 O 11 phase. Transmission electron microsc...

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...
