Simultaneous Deposition of Different Phase‐Change Alloys Through a Nanopillars Shadow Procedure

physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 7, July 2026.
A deposition strategy enabling controlled nanoscale stoichiometry modulation in Ge‐Sb‐Te phase‐change materials is presented. Directional elemental fluxes and shadowing effects induced by nanopillar arrays generate distinct Ge‐, Sb‐, and Te‐deficient regions within a single specimen.

Unveiling Non‐classical Pathways in Copper Electrodeposition via In Situ Electrochemical Liquid‐Cell Transmission Electron Microscopy

Small Science, Volume 6, Issue 7, July 2026.
In situ electrochemical transmission electron microscopy reveals dynamic nanoparticle behavior during copper electrodeposition, from lateral motion and Ostwald ripening to coalescence and surface‐energy‐driven restructuring. These nanoscale processes occur “silently,” undetectable in bulk electrochemical signals, highlighting the importance of real ...

A simulation approach for quantifying ballistic impact damage in ultra-high-performance concrete

In this work, we provide a hydrocode simulation model for high-velocity projectile impact against ultra-high-performance concrete targets and establish a methodology to extract damage quantities from the simulation results.

Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

Journal of Forensic Sciences, Volume 71, Issue 4, Page 1607-1620, July 2026.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Infants and Mobiles: Developing an Understanding of Cause and Effect

Developmental Science, Volume 29, Issue 4, July 2026.
ABSTRACT In the mobile conjugate reinforcement paradigm, an infant's leg is connected to a mobile via a string, allowing the infant to move the mobile via moving their leg. Over a few minutes, infants exhibit an increase in the frequency of movement of the connected leg.

Hot Electron‐Informed Quantum Plasmonics in Nanoparticle‐on‐Mirror Nanocavities

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
A computational model for ultrafast optical modulation of quantum phenomena at plasmonic metal interfaces is developed. Focusing on nanoparticle‐on‐mirror nanocavities, it describes temperature‐induced variations in electronic quantum behavior. This facilitates analysis of quantum plasmonics in non‐equilibrium systems, thereby expanding the realm of ...

Modeling of advanced combat helmet under ballistic impact

, 2015
The use of combat helmets has greatly reduced penetrating injuries and saved lives of many soldiers. However, behind helmet blunt trauma (BHBT) has emerged as a serious injury type experienced by soldiers in battlefields. BHBT results from nonpenetrating
