The third ASTM symposium on damage in laser materials held at NBS in May 1971 is discussed, and the results are reviewed.
Polymorphism often occurs in energetic materials. Differences in the forms range from conformational changes in the molecule from one system to another, to conformational equivalents packing in different manners. These differences, whether drastic or subtle, can lead to substantial alterations in stability and performance. The authors recently reported on the crystal structures of five polymorp...

In general, thermodynamics is the study of laws governing processes which involve heat changes. It includes the study of conditions under which various substances exist in chemical equilibria, the consequences of chemical reactions and the interchange of heat and other forms of energy when a chemical re action occurs. In the field of nuclear technology, it is necessary to know how construction ...
A short history of interconnects in high and intermediate temperature solide oxide fuel cells form those based on ceramics to those made of metals.
