Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

The elastic properties of silica phases are reviewed. Available monocrystal data for
crystalline SiO2 polymorphs (low-quartz, high-quartz, low-cristobalite, high-cristobalite …

In comparing a material's resistance to distort under mechanical load rather than to alter in
volume, Poisson's ratio offers the fundamental metric by which to compare the performance …

A preliminary study of a promising bi-layer environmental barrier coating (EBC) designed to
reduce the susceptibility of SiC composites to hot water vapor erosion is reported. The EBC …

A recently optimized air plasma spray process has been used to deposit a model tri-layer Yb
2 SiO 5/Al 6 Si 2 O 13/Si environmental barrier coating (EBC) system on α-SiC substrates …

An air plasma spray process has been used to apply a model tri‐layer Yb2SiO5/Al6Si2O13/
Si environmental barrier coating system on SiC test coupons. Significant differences in the …

Progress in seismic methodology and ambitious large‐scale seismic projects are enabling
high‐resolution imaging of the continental crust. The ability to constrain interpretations of …

To interpret seismic images, rock seismic velocities need to be calculated at elevated
pressure and temperature for arbitrary compositions. This technical report describes an …

Elastic geobarometry for host-inclusion systems can provide new constraints to assess the
pressure and temperature conditions attained during metamorphism. Current experimental …

This research has investigated the mechanical properties and microstructure of metakaolin
derived geopolymer mortars containing 50% by weight of silica sand, after exposure to …
