Advancing graphene-enabled piezoelectric, triboelectric, and hybrid nanogenerators: A review on mechanistic and performance optimization

Graphene significantly enhances the performance of piezoelectric (PENG), triboelectric (TENG), and hybrid piezoelectric-triboelectric (H-P/TENG) nanogenerators by regulating polarization, dielectric behavior, charge transport, and interfacial coupling. This review presents a crit...

Morphology, Thermal Behaviour, Abrasion Mass Loss, and UV-Induced Coffee-Stain Discolouration of TiO2-Coated Polyester Fabrics Treated at Different Coating Temperatures

The coating temperature during TiO2 treatment can influence particle deposition, abrasion behaviour, and stain discolouration of polyester fabrics. However, the relationship between coating temperature and the resulting structural and functional properties requires further evalua...

Worsening Hypertensive Control as a Clue to High-Grade Brachiocephalic and Subclavian Artery Stenosis in Primary Care: A Case Report

Objective: Unusual clinical course Background:Upper-extremity peripheral arterial disease (PAD) is a less common manifestation of peripheral arterial disease than lower-extremity PAD.Many patients with upper-extremity PAD remain asymptomatic until significant arterial stenosis de...

Influence of culm position and regional growth conditions on the tensile strength perpendicular to the grain

Bamboo has received increasing attention as a sustainable structural material; however, its tensile strength perpendicular to the grain remains elusive in governing splitting failure, particularly in joint and connection design. This study experimentally investigates the tensile...

Pedestrian-level wind environment within the intervening space between elevated towers above a podium: Effects of core geometry and wind direction

An intervening space, which is typically situated between buildings over the podium, has been increasingly incorporated into residential developments, yet its pedestrian-level wind environment (PLWE) remains insufficiently investigated. This study combines wind tunnel experiments...

Herpes Zoster in an Immunocompetent Child Following an Influenza-Like Illness

Herpes zoster (HZ) or shingles is uncommon in children and is traditionally associated with advancing age and immunocompromised states. However, HZ may also occur in immunocompetent children, in whom diagnosis may be overlooked due to its rarity and broad differential diagnosis o...

A literature-derived database and machine learning-assisted analysis of compressive strength retention in biochar-modified cementitious composites

Biochar has attracted growing interest as a carbon-rich additive or partial cement replacement in cementitious composites, but published data remain fragmented across feedstocks, processing conditions, mixture designs and material types. This study compiled a structured database...

A qualitative study on feeding experiences among caregivers of children with cerebral palsy requiring food texture modification

Background and purpose Children with cerebral palsy often experience feeding difficulties that require food texture modification and are highly dependent on their caregivers, which commonly lead to malnutrition. This study aimed to explore caregiver's current practices, perceptio...

Epoxidation of Waste Palm Cooking Applied With Hybrid Zeolite Catalyst Derived From Natural Clinoptilolite/Synthetic ZSM ‐5

ABSTRACT Catalyst development for epoxidation is constrained by the trade‐off between efficiency, cost, and sustainability. Homogeneous catalysts such as sulfuric, hydrochloric, and acetic acids exhibit high activity but are limited by corrosiveness, environmental concerns, and l...

Visual elements in food packaging and consumer choice: a moderated mediation analysis of consumer satisfaction in the tea market

This study examines how consumer satisfaction moderates the relationship between visual packaging elements and purchase intention in low-involvement products. Whilst packaging design’s influence on purchase decisions is well-documented, understanding of boundary conditions remain...
