Energy Science &Engineering, EarlyView.This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

A Unified Framework for Producing CAI Melting, Wark-Lovering Rims and Bowl-Shaped CAIs
, 2016 Calcium Aluminium Inclusions (CAIs) formed in the Solar System, some 4,567 million years ago. CAIs are almost always surrounded by Wark-Lovering Rims (WLRs), which are a sequence of thin, mono/bi-mineralic layers of refractory minerals, with a total ...

Robust multi-fidelity design of a micro re-entry unmanned space vehicle [PDF]
, 2011 This article addresses the preliminary robust design of a small-scale re-entry unmanned space vehicle by means of a hybrid optimization technique. The approach, developed in this article, closely couples an evolutionary multi-objective algorithm with a ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Composite materials hold significant potential for abrasive sealing, yet composite materials used for abrasive sealing fall short in service durability under extreme environments. Here, a controllable strategy for adjusting pore structure is proposed, aiming to design a YSZ(ESP)/BN@ZrO2‐polyester coating with hybrid micron/nanometer ...

Radiative Forcing and Ozone Depletion of a Decade of Satellite Megaconstellation Missions
Earth's Future, Volume 14, Issue 5, May 2026.Abstract Satellite megaconstellations (SMCs) are driving rapid increases in rocket launch and re‐entry rates, emitting pollutants throughout the atmosphere. The environmental impact of SMCs lacks characterization to determine the need for regulation. We utilize a global 3D emission inventory of recent (2020–2022) space activity that distinguishes SMC ...

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.The local carbon environment in the refractory transition metal carbides ZrC, HfC, NbC, and TaC was studied using high‐resolution magic angle spinning 13C NMR spectroscopy. Results show that carbon nuclei with next nearest neighbor vacant sites or oxygen/nitrogen impurities are distinguishable through 13C NMR, and that the technique can be used to ...
