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.

Experimental study of sandwich structures as armour against medium-velocity impacts [PDF]

, 2013
An experimental impact study has been conducted on sandwich structures to identify and improve armour solutions for aeronautical applications. The objectives are to find the best configurations, i.e. the non-perforated targets with the minimal weight and

Experimental study on the dependency of the ballistic performance of tiled ceramic/metal targets on inter tile gap width and projectile impact position

, 2022
S.50-59Inter tile gaps are points of higher vulnerability of tiled armor systems. For the design of armor systems, the knowledge of this weakness effect is essential.

Predicting Crystal Structures and Ionic Conductivities in Li3YCl6−xBrx Halide Solid Electrolytes Using a Fine‐Tuned Machine Learning Interatomic Potential

Advanced Intelligent Systems, EarlyView.
This study refines the Crystal Hamiltonian Graph Network to predict energies, structures, and lithium‐ion dynamics in halide electrolytes. By generating ordered structural models and using an iterative fine‐tuning workflow, we achieve near‐ab initio accuracy for phase stability and ionic transport predictions.

Ballistic Impacts on Bone: Effect of Preloading [PDF]

Human Factors and Mechanical Engineering for Defense and Safety, 2018
An experiment to investigate the effect of preloading on bone impacts by projectiles was undertaken. During this experiment, a total of 59 bones were impacted. Red deer tibias were used, with impacts to the shaft under three different loading conditions. The purpose of the trial was to provide an indication on whether preloading a bone has an effect on

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

Journal of Applied Polymer Science, EarlyView.
Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

A numerical study on the impact behavior of foam-cored cylindrical sandwich shells subjected to normal/oblique impact

Latin American Journal of Solids and Structures
Finite element analysis was used to investigate the impact behavior of the foam-cored sandwich shells under the ballistic impact. The ballistic limit, failure mode of the face-sheet and energy absorption of the uniform/graded core were discussed in this ...
