Low‐Velocity Impact Response of Nacre‐Inspired E‐Glass/Epoxy Composites With Varying Platelet Sizes

open access: yesPolymer Composites, Volume 47, Issue 3, Page 2781-2798, 10 February 2026.
Impact response of nacre‐inspired E‐glass/epoxy composites with different platelet sizes. ABSTRACT This study explores the low‐velocity impact behavior of nacre‐inspired biomimetic platelet composites (NIBPC), using low‐cost E‐glass fiber in chopped strand mat (CSM) form as reinforcement and epoxy resin as the matrix.

Casus Belli

open access: yesKyklos, Volume 79, Issue 1, Page 17-23, February 2026.
ABSTRACT This article proposes that wars are fought to bring about and monitor mutual reductions of overinvestment in broadly defined military preparedness. If two potential combatants are overinvested in military preparedness, it is in their individual interest to scale down in order to use their resources in politically more desirable ways.

Sampling the volcanic plumes at Io: Impact speeds and shock conditions

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 2, Page 241-271, February 2026.
Abstract The desire to sample material from the interior of Io, by flying through its volcanic plumes, requires consideration of the flyby speed and the types of sample collection techniques that can be utilized. Low speed collection (1–2.5 km s−1) would require an orbit around Io itself, which is unlikely due to the accumulated radiation dose that ...
