Functional gradient materials (FGMs) have a microstructurally graded transition in composition (e.g. zirconia to a nickel based superalloy). The graded transition eliminates problems associated with a discrete interface such as poor mechanical strength and transport losses. They are being actively pursued by the engineering community, particularly in Japan, as a means of taking advantage of two di ...

The proposed program is to develop the use of aqueous biopolymers for the solid freeform fabrication of ceramic components. It will be a collaborative effort between ACR and Battelle PNL. PNL has expertise in colloidal ceramic processing and experience on utilizing biopolymers in ceramic slurries. ACR has already developed extensive software and hardware capability for solid freeform fabricatio ...

There is a need for accurate and cost effective airborne techniques to estimate fish biomass in the open ocean. Arete proposes to develop in Phase I optimal detection algorithms using existing imaging LIDAR data collected with the Fisheye(R) sensor. These algorithms will be developed to allow real-time detection of fish and fish schools, discrimination between fish and ambient clutter, and discr ...

An advanced ceramic heat recuperator (ACHR) incorporates thin corrugated,d triangular-shaped flow channels made of non-oxide ceramics with high thermal conductivity and high fracture toughness. A counterflow arrangement together with the unique design of the flow channels makes the ACHR highly efficient, highly reliable and compact. A key processing innovation is also made for fabrication of the ...
