On Determining Continuum Quantities of Non-Equilibrium Processes via Molecular Dynamics Simulations [PDF]

open access: yes, 2013
In this dissertation, a high-fidelity atomistic-to-continuum link for highly non-equilibrium processes has been established by making several modifications to Hardy’s theory.

AI‐Guided Co‐Optimization of Advanced Field‐Effect Transistors: Bridging Material, Device, and Fabrication Design

open access: yesAdvanced Intelligent Discovery, EarlyView.
This article outlines how artificial intelligence could reshape the design of next‐generation transistors as traditional scaling reaches its limits. It discusses emerging roles of machine learning across materials selection, device modeling, and fabrication processes, and highlights hierarchical reinforcement learning as a promising framework for ...

Numerical investigation on effect of different projectile nose shapes on ballistic impact of additively manufactured AlSi10Mg alloy

open access: yesFrontiers in Materials
In the last few years, due to the superior mechanical qualities of Additive Manufacturing (AM) AlSi10Mg alloy to those of traditional casting process AlSi10Mg alloys, the application of AM technology has significantly increased.

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

open access: yesAdvanced 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.

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

open access: yesJournal 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

Simplified simulation of impact bullet - stratified pack for restraining ballistic tests [PDF]

open access: yesMATEC Web of Conferences, 2017
This paper presents a macro FEM isothermal model for simulating the impact of a 9 mm FMJ bullet on a stratified packs in order to restrain the preliminary tests for actual stratified packs made of layers of Twaron LFT SB1plus (Teijin), taking into account the friction between layers and between bullet and layers, in order to obtain the number of layers

Behind helmet blunt trauma induced by ballistic impact : a computational model

open access: yes, 2016
Behind helmet blunt trauma (BHBT) has emerged as a serious injury type experienced by soldiers in battlefields. BHBT has been found to range from skin lacerations to brain damage and extensive skull fracture.

Dynamic mechanical response and failure behaviour of AlMgB14-based ceramic: experimental observation, constitutive modelling and ballistic performance evaluation

open access: yesJournal of Materials Research and Technology
AlMgB14-based ceramics have emerged as promising materials for ballistic protection due to their ultra-hardness and low density. However, their dynamic mechanical behaviour and ballistic performance remain underexplored.

Surface Charges Guided Quasi‐TEM‐mode Microwave Propagation along Dielectric Nanowire

open access: yesAdvanced Physics Research, EarlyView.
According to Maxwell's equations, a single‐conductor transmission line cannot allow TEM‐mode electromagnetic wave propagation, however, this is based upon the assumption that dielectric material is isolated from the environment. In practice, surface electrostatic charges widely existed in nano‐materials with large surface‐to‐volume ratio.
