A Cu(II) complex-driven supramolecular array: synthesis, crystal structure, Hirshfeld surface analysis and application in dyes adsorption

Using benzilic acid (BA) and 1-Methylimidazole (1-Me-Imi) ligands, a new Cu(II) complex is prepared, formulated as, [Cu(BA)2(1-Me-Imi)2(H2O)] (1). In the structure, the Cu(II) metal ion adopted a distorted square-pyramidal geometry, completed by two BA ligands, two 1-Me-Imi ligan...

Geometric Properties, Partial Sums, and Fekete–Szegö Inequalities for a Normalized Four-Parameter Le Roy-Type q-Mittag–Leffler Function

In this paper, we introduce and study a normalized four-parameter Le Roy-type q-Mittag–Leffler (LR-q-ML) function defined by means of the q-Pochhammer symbol, the q-Gamma function, and the q-factorial, whose parameters directly influence the associated coefficient sequence and it...

Burnout and resilience among healthcare nurses in Saudi Arabia: a cross-sectional study with exploratory multiclass classification approach

Burnout is a significant occupational and psychological concern among nurses. However, there is an evidence gap in research considering the dimensions of burnout and resilience in healthcare settings where the nursing workforce is predominantly expatriate. Therefore, this study a...

Behavioural biometrics-based continuous authentication using transformer networks for detecting insider-threat session hijacking

Abstract Insider threats, in which a legitimate user’s already-authenticated session is taken over by another enrolled individual, evade one-time login authentication because the session is trusted before the takeover occurs. Continuous authentication, which re-verifies the user...

Advanced experimental analysis on the synthesis and modification of zinc iron-based nanoparticles for separation and removal of pharmaceutical compounds

This study reports the visible-light-driven photocatalytic degradation of tetracycline (TC) in aqueous media using porous Co-doped ZnFe₂O₄ microspheres. ZnFe 2 O 4 (ZF) microspheres with a porous, spherical morphology were synthesized and subsequently doped with 5 wt% and 15 wt%...

3D‐Printed Mold‐Cast MWCNT/PDMS Flexible Heatsinks for Thermal Management

ABSTRACT The innovative concept of converting solid thermal conductors into flexible components is emerging as a compelling development in materials science and electronics. Flexible heatsink designs offer dynamic and adaptable solutions in the field of thermal management. This s...

Smoking Cessation Knowledge among Community Pharmacists in Saudi Arabia

Introduction Tobacco use remains one of the most pressing global public health challenges, contributing substantially to the incidence of preventable diseases and premature mortality. In Saudi Arabia, tobacco consumption continues to rise, with an estimated 21.4% of adults identi...

Integrating Azotobacter inoculation with nano-NPK foliar application: a sustainable strategy for enhancing growth, physiology, and sugar yield in sugar beet (Beta vulgaris L.)

Sugar beet is a key crop for the sugar industry, increasingly reliant on eco-friendly inputs to meet rising global demand. Plant growth-promoting rhizobacteria (PGPR) enhance plant growth via root associations, while nanotechnology offers solutions to limitations of traditional f...

An Insight into Solventless Reaction Techniques of Monovalent Coinage Metal Complexes

The use of solventless synthetic methods is becoming important in green chemistry, as they allow the production of synthetic organic molecules in a way that is less environmentally harmful and requires less waste, energy, and impact than traditional solvent-mediated methods. In t...

Application of in vitro digestion and dialysability procedure for bioavailability evaluation of toxic elements in green leafy vegetables: a realistic health risk assessment by Monte Carlo simulation

Green leafy vegetables (GLVs), which are vital and widely consumed worldwide, require monitoring for contaminants, including toxic elements (TEs). This study measured total concentrations (TC) and bioavailable concentrations (BC) of arsenic (As), cadmium (Cd), lead (Pb), chromium...

Associations of screen time and physical activity with motor control, mood, and cognitive states in adolescents following acute high-intensity interval training

Excessive screen time and insufficient physical activity are increasingly common among adolescents and have been linked to adverse physical and psychological health outcomes. This school-based cross-sectional study examined associations between sedentary screen time, physical act...

Assessment of anxiety levels and marital relationships among women undergoing infertility treatment: A descriptive observational study

This study aimed to assess anxiety levels and marital relationships among women undergoing infertility treatment. A descriptive observational design was conducted involving 300 infertile women over nine months at Zagazig University Hospital. Data were collected using a Structured...

Public Knowledge, Practices, and Acceptance of Smart Health Technologies Addressing Antibiotic Use and Resistance in Saudi Arabia

Background: Antimicrobial resistance (AMR) remains a major global public health threat, largely driven by inappropriate antibiotic use. Smart health technologies (SHTs), including mobile health applications and digital stewardship tools, offer promising opportunities to improve a...

A sensitive and green spectrofluorimetric method for determination of guanfacine hydrochloride based on NBD-Cl derivatization

A sensitive and environmentally friendly spectrofluorimetric method was developed for the determination of guanfacine in pharmaceutical formulations. The method is based on derivatization of guanfacine with 4-chloro-7-nitrobenzofurazan in alkaline medium to yield a highly fluores...

Comparative analysis of cerium incorporation techniques on Ni/Al2O3 catalysts for methane dry reforming: Surface promotion vs. structural support modification

Two series of 5 wt.% Ni/Al 2 O 3 catalysts incorporating cerium (Ce) at loadings ranging from 1.0 to 3.0 wt.% were prepared by impregnation and subjected to systematic evaluation for the dry reforming of methane (DRM) at 700 °C. The two series were distinguished by the mode of Ce...
