Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Thermoelectric Response and Field‐Induced Figure of Merit in Fluorine–Doped Carbon Nanotube Using the Lorenz Number

Advanced Physics Research, EarlyView.
Thermoelectric conductivity decreases nonlinearly with increasing temperature for all investigated band‐gap values. Higher energy splitting yields lower conductivity, while smaller gaps maintain superior carrier transport. Peak response occurs at low temperature, followed by gradual saturation at elevated temperatures.

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

The Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Ballistic Performance Evaluation of Aluminium Plate Impact by Fragment Simulating Projectile

Journal of Physics: Conference Series, 2020
Abstract The ballistic performance has drawn attention to researchers from a military background. They intend to provide solutions to ensure the soldiers in the front line of war do not kill in action. A casualty in war can lead to depression among soldiers and not to mention to their family as well.
