Studies on cation exchange membranes (perpmaplex-C-20)
The investigations described in this thesis have been aimed at contributing to the understanding of equilibrium and non-equilibrium phenomena in ion-exchange membranes. Towards this end, Permaplex C-20 has been chosen as ... -
Physiocochemical investigations on urea-nitrate calcium phosphate system
The experimental results obtained in the present investigation clearly demonstrate that when urea nitrate is ground with tribasic calcium orthophosphate, a reaction takes place in the solid-state even at laboratory temperature ... -
Substitutent and solvent effectson the electronic adsorption spectra of organic molecules, spectroscopy of nonbonded electrons.
The above results show that both the substituent and nitrogen on the N-transition of alkyl iodides are similar to those on the N-alkylamines, and the differences lie in rather three points. This is not surprising because ... -
Time resolved resonance raman studies on photo-induced electron transfer reaction
Time-Resolved Resonance Raman Studies on Proton-Induced Electron Transfer Reaction from Triplet 2-Methoxy-Naphthalene to Benzophenone In this chapter, the effect of solvent polarity on the mechanism and the nature of ... -
Time-resolved resonance Raman spectroscopic studies on photoinduced transients
Transient absorption spectroscopy has been applied to find the relative yield of the radical cations for PVCz and PDBVCz. It has been found that the ratio of the relative yield of the radical cation for monomer to polymer ...
