Polymer Composites, EarlyView.The effect of molecular structure on the moisture absorption of PLA/cellulose biocomposites. Abstract This study investigates the effect of annealing heat treatment on polymer composites composed entirely of biodegradable components. Poly(lactic acid) (PLA) was used as the matrix material paired with three different types of commercial lignocellulose ...

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

ADAPTIVE SIMULATION OF THE INTERNAL FLOW IN A ROCKET NOZZLE
Latin American Applied Research - An international journal, 2014 This work is a first step in the understanding of the interaction process between internal shock waves and the flow transition inside of a rocket nozzle that develops during the engine start-up phase or when the nozzle is operated at overexpanded conditions.

Effects of Galactic Irradiation on Thermal and Electronic Transport in Tungsten
physica status solidi (b), EarlyView.This atomic‐scale study reveals how low‐to‐mid‐energy space irradiation alters tungsten's thermal and electronic behavior, even at low defect levels. Focusing on vacancy sites in bulk and near grain boundaries, it employs two novel approaches: site‐projected thermal conductivity and the N2$^{2}$ method for the thermal and electronic response analysis ...
