Controllable Ge Hut Wires With Mobilities Exceeding 20 000 cm2 V−1 s−1

Advanced Electronic Materials, EarlyView.
The controlled growth of germanium hut wires on patterned SiGe/Si(001) substrates is reported. These self‐assembled nanowires achieve a record hole mobility of 22 900 cm2 V−1 s−1 at 4.2 K. Remarkably, conductance quantization is observed at a channel length of 1.9 µm, highlighting their exceptionally low disorder and paving the way for scalable, high ...

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.

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

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.

The Tendon‐to‐Bone Seam: A Transtendinous Approach to Rotator Cuff Repair

Arthroscopy Techniques, EarlyView.
Abstract This technique article describes the tendon‐to‐bone seam technique, a knotless, transtendinous approach to arthroscopic rotator cuff repair. The technique employs a single‐use deployment device preloaded with multiple PEEK anchors interconnected with a single polyethylene #2 suture, enabling the surgeon to create a continuous “seam” of ...

Numerical Study on Ballistic Phenomena - Part Two

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2016
The study of ballistic phenomena (interior ballistics, exterior ballistics and terminal ballistics) is an activity that involves the use of complex and at the same time very expensive equipment.

Maximizing Neurovascular Outcomes of Facial Transplantation: A Comprehensive Review

Clinical Anatomy, EarlyView.
ABSTRACT Facial transplantation is a division of reconstructive surgery which aims to improve the function and appearance of a face that has endured severe disfigurement. Currently, the face transplant procedure uses allogenic tissue, harvested from a brain‐dead donor, to replace damaged facial components.

Development of a Numerical Model of the 9 mm Parabellum FMJ Bullet Including Jacket Failure

Engineering Transactions, 2014
Even though ballistic experiments are widely accepted as the only reliable way to probe terminal effects, we demonstrate that computer simulation can be a useful alternative.
