Can we make a more inexpensive and greener coating using naturally forming minerals? Xenotime mineral composition was determined to be (Y0.80Gd0.04Dy0.07Er0.05Yb0.04)PO4. Preliminary studies into REPO4 species showed compatable CTE match with SiC, formation of a multilayer reaction product that improves CMAS resistance, and parabolic growth rates ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
