Chemical petrology of ultramafites and the origin of magnesite deposites of Musorre District, Karnataka
Any attempt to classify the ultramafites of the Sindhuvalli–Talur area should take into consideration the field features, petrography, and the chemistry of the whole rock as well as the individual mineral phases. Field ... -
Studies on combustion of solid composite propellants condensed mixtures.
Combustion of solid composite propellant is characterised by its rapidity and the highly complex nature of the various physico chemical phenomena taking place both in the flame zone and in the solid phase of the combustion ... -
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 ... -
Tetrathiomolybdate : a versatile reagent in organic synthesis
The simplest binary Mo–S moiety is MoS². Although this ion has been known in the literature for many years, its chemical reactivity has only recently been appreciated. MoS² has been extensively used by synthetic inorganic ... -

Insertion Reactions of copper (I) Aryloxides with heterocumulenes
Studies on alkoxide and aryloxide complexes of copper(I) are significant due to their relevance to biological systems and their potential in small molecule activation. In the present investigation, the insertion reaction ... -
Thermal decomposition studies on the exalate of uranium(IV), praseodymium and neodynium
Thermogravimetric Analysis: The decahydrate on heating gives rise to a monohydrate, which loses its last mole of water on further heating to give the anhydrous oxalate that is quite stable in the range 350–400°C. The oxalate ... -
Theoretical investigations on fluxionality, molecular devices and chemical binding
In the recent past, considerable attention has been focused on the design and synthesis of molecular devices [1]. Molecules that can perform various kinds of interesting motions, such as ratcheting, shuttling, harpooning, ... -
Novel electronic structures in transition metal oxides
