Investigations of the interaction of molecules with clean and modified transition metal surfaces by techniques of electron spectroscopy
We have hitherto discussed the features of adsorbed oxygen on a variety of metal surfaces as characterised by the techniques of electron spectroscopy. Specifically, the characteristics of the different oxygen species O²?, ... -
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 ... -
Ion insertion and Ion-host Interactions in Diketopyrrolopyrrole-based π-Conjugated Polymers
π-conjugated organic semiconductors are a class of technologically important materials with broad applicability in areas as diverse as energy conversion and storage, bioelectronics, and consumer electronics. This is because ... -
Isolation and functional charecteristics of xylanases and cellulases of thermoascus aurantiacus
Highly-dispersed platinized-carbon hydrogen anodes are developed for utilization in alkaline and acidic media hydrogen/air fuel cells by tailor-making both their macro and microstructures. The present hydrogen anodes are ... -
Layered Oxides And Phosphates Of Bismuth: New Structural Types And Related Properties
