He certified as BL and MA and is an advocate by occupation. Photosensitization of nanoparticles of semiconductors, anatase TiO2 and ZnO by the excited states of dyes in meso and microporous silicate hosts is investigated using pico and femtosecond fluorescence and transient absorptions techniques and the results are reviewed. Durai Murugan is an Indian lawyer, Politician, and Spokesperson who’s the present chairperson of Dravida Munnetra Kazhagam (DMK). Picosecond and femtosecond diffuse reflectance fluorescence investigations in the porous solid host materials show intramolecular proton transfer reactions of the dyes and deprotonation of the dyes in the excited states. Top Courses at Durai Murugan College of Education Vellore, Tamil Nadu are B. Photoredox reactions of thiazine and safranine dyes are investigated using time resolved absorption and emission techniques in solution and on encapsulation in micro and mesoporous host materials. Durai Murugan College of Education,Vellore, Tamil Nadu has 4 Courses with Average Fees 30,500 per year. Some of the photolysis reactions investigated provide details in real time including the thermal reactions of molecular oxygen with cobalt(II) amine systems and the cobalt (III) alkyl complex formation on photolysis of cobalt(III) aminoacid complexes. The excitation flash radiation initially was limited to flash lamps with a time resolution to study the decay of the excited states and the fast reactions of photo produced transients in milliseconds and microseconds. more The photoredox reactions of cobalt(III), nickel(II) complexes and organic dyes are reviewed with particular emphasis on using flash photolysis methods to identify the transients in the time scale from milliseconds to subpicoseconds. The photoredox reactions of cobalt(III), nickel(II) complexes and organic dyes are reviewed with. It is suggested that the fractals result from the interpolymer adduct by Diffusion Limited In presence of salts, sodiumĬhloride or potassium chloride, micellar like entities of 80 nm size were formed which further aggregate toįorm fractal patterns. The composition of the fractals in the film is studied by EDXĪnd confocal microscopic images of the fluorophores covalently bound to PMAA. Fractal formation occursĭue to the aggregation of interpolymer adducts. Sodium chloride formation of the fractals in films of the adducts is a novel observation. Of PMAA with complementary polymers such as poly(vinylpyrrolidone) is well-known and in the presence of The structure, morphology and the conditions under which the formation ofįractal patterns occurs were investigated by SEM, EDX and confocal microscopic techniques. Of sodium chloride or potassium chloride form highly ordered fractal patterns in films on glass surface onĭrying at ambient temperature. more Interpolymer adducts of poly(methacrylic acid), (PMAA), with poly(vinylpyrrolidone) in presence Interpolymer adducts of poly(methacrylic acid), (PMAA), with poly(vinylpyrrolidone) in presence
