Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments

Journal of Raman Spectroscopy, Volume 57, Issue 8, Page 1392-1406, August 2026.
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

Purification and Properties of Polyvinyl Nitrate and Its Compatibility With Solid Oxidizers

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 8, Page 1224-1234, August 2026.
ABSTRACT Polyvinyl nitrate (PVN) is a nitrate‐ester energetic binder that can be produced directly from polyvinyl alcohol—a cheap commodity feedstock—thereby offering potential cost and supply‐chain advantages over binders based on nitrocellulose and other specialty polymers.

Microstructure Tailoring of Laser Powder Bed Fused Nb521 Alloy Toward Strength‐Ductility Synergy

Rare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT Niobium‐based refractory alloys are promising candidates for high‐temperature aerospace structures, yet their limited ambient‐temperature ductility and poor processability remain major barriers to broader implementation. Here, Nb521 alloy was fabricated by laser powder bed fusion (LPBF), and the effects of processing conditions and subsequent ...

Basins of Attraction and Escape in Pendulum‐Type Potentials with Quadratic Air Drag

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 8, August 2026.
ABSTRACT Quadratic air drag is a common dissipative mechanism at moderate to high velocities, yet in nonlinear one‐degree‐of‐freedom systems, it typically blocks closed‐form solutions and energy‐based phase‐plane partitions. We study the autonomous class ẍ+α(x)|ẋ|ẋ+β(x)sgn(ẋ)+V′(x)=0,$$\begin{equation*} \ddot{x}+\alpha (x)\,|\dot{x}|\,\dot{x}+\beta
