Role of Mn3+/Mn4+ redox-coupled oxygen vacancy modulation in SnO2 nanoarchitectures for ultrasensitive acetone detection

Acetone (CH 3 COCH 3 ) is a ubiquitous volatile organic compound in industrial and laboratory settings; however, its high volatility and toxicity necessitate advanced monitoring to ensure human health and occupational safety. In this work, we report a highly sensitive and selecti...

Electrochemical sensors for melamine and clenbuterol in food

Food safety remains a critical global concern as escalating demand and intensified market competition continue to drive economically motivated adulteration (EMA). The unauthorized inclusion of substances such as melamine (MEL) and clenbuterol (CLB) poses a severe public health ri...

Colloidal and lithographic polymer templated nanostructures for chemiresistive gas sensors and intelligent gas discrimination

Metal-oxide-semiconductor (MOS)-based chemiresistive gas sensors are promising for real-time detection, but poor gas accessibility, stochastic charge transport, low selectivity, and high thermal burdens hinder their practical translation. Polymer templating provides a powerful ar...

One‑step spray‑coated self-stratified PDMS/P(VDF‑TrFE) hybrid fibrous composite-based Triboelectric Nanogenerators

Fibrous architectures have emerged as highly promising platforms for triboelectric nanogenerators (TENGs) due to their large surface area, mechanical flexibility, and enhanced mechanical-to-electrical energy conversion efficiency. However, conventional fabrication strategies for...

Accuracy Verification and Correction of a Depth-Camera-Based Digital Measurement System for Pelvic Balance Assessment in the Trendelenburg Test

This study proposes a markerless, single-camera depth-sensing system for digitally quantifying pelvic-balance ability in the Trendelenburg test, and verifies its accuracy and reliability against a marker-based motion capture (MC) reference and manual measurement (MM) in 16 health...

Digital Connectivity and Human Capital Development: Understanding the Distraction Paradox in Higher Education Using Structural Equation Modelling

Abstract Digital technologies have rapidly transformed teaching and learning in higher education in recent years, reshaping the learning environment alongside factors that influence technology acceptance and users' digital competence. Grounded in the Technology Acceptance Model (...

A Scoping Review of In-Vehicle VR Sickness Factors: A Multidisciplinary Perspective

Mitigating in-vehicle VR sickness is a critical challenge for the use of immersive content in autonomous vehicles. In this study, to solve in-vehicle VR sickness, the cause of motion sickness in each field is identified by conducting a scoping review in three fields (medicine, co...

A VR Sickness Reduction Method Using Visual Guide Transparency

As VR hardware advances, hardware-related factors inducing motion sickness are expected to be gradually resolved; consequently, software-based mitigation methods are garnering significant attention. While various software-based methods exist, they often rely on modifying the cont...
