Nanofibrillated Cellulose–Regolith Composite Aerogels for Lunar Thermal Insulation

Abstract Life support systems in extraterrestrial settings face severe material constraints, demanding innovative in situ resource utilization (ISRU) strategies. One material that merits attention is cellulose, which can be procured in relative abundance from locally generated wa...

Evaluation of Particle Degradation of a Ytterbium Disilicate Gas Turbine Coating in a Combustion Environment

Abstract Ytterbium disilicate (Yb2Si2O7) is a state-of-the-art topcoat material used in environmental barrier coatings (EBCs) to protect SiC-SiC composites from water vapor induced corrosion in gas turbine engines. However, its degradation by thermochemical and thermomechanical p...
