INVESTIGATIONS ON Positive Temperature Coefficient of Resistance OF POLYCRYSTALLINE BARIUM TITANATE
The way similar to monomerisation or at higher temperatures. CD studies indicated no major change in the secondary structure of the proteins of lipovitellins during chloroform absorption. The interaction of Ca²? and Na? ... -
Investigations On Size Dependence Of Diffusivity In Condensed Media
(2010-08-24)Diffusion plays an important role in a number of processes like heterogeneous catalysis, corrosion, separation and purification of chemicals of industrial importance, steel hardening, fuel cells, and solid electrolytes for ... -
Investigations On Size Dependence Of Diffusivity In Condensed Media
In summary, the present work reports results for diatomic species AB in zeolite NaY. The results show that when A = B, there is a maximum in the self-diffusivity of the diatomic molecule at large bond lengths c_lab. This ... -
