in this research, the tacticity and microstructure of polyvinyl chloride (pvc) were studied through back bone methylene and methine carbons and protons splitting by carbon (13c nmr), proton (1h nmr) and two-dimensional (2dnmr) nulear magnetic resonance spectroscopy in deuterated etrahydrofuran.polyvinyl chloride was synthesized by emulsion polymerization of vinyl chloride (vcm) under pressure t...

[To my family for their love and support] iv ACKNOWLEDGEMENTS There are many people I would like to thank for their support throughout my Ph.D. study at Georgia Tech. I would like first express my tons of gratitude to my advisor Dr. Behrens for his invaluable support that I will remember for ever. I will remember his great guidance whenever I encounter a problem in my thesis work; I will rememb...

hybrid nanocomposites of binary pt-ru/polyaniline were prepared by oxidative polymerization of aniline andformation pt and ru nanoparticles. the polymerization of aniline was carried out in the presence of potassiumhexa cyano platinate (iv) and ruthenium (iii) nitrosyl nitrate as oxidizing agents. during the reaction anilinemonomers undergo oxidation and form polyaniline (pani) whereas the redu...

The manufacturing of stable emulsion is a very important challenge for the cosmetic industry, which has motivated intense research activity replacing conventional molecular stabilizers with colloidal particles. These allow minimizing hazards and risks associated use stabilizers, providing enhanced stability to obtained dispersions. Therefore, particle-stabilized emulsions (Pickering emulsions) ...

A Pickering emulsion based on sodium starch octenyl succinate (SSOS) was prepared and its effects the physicochemical properties of hairtail myofibrillar protein gels (MPGs) subjected to multiple freeze-thaw (F-T) cycles were investigated. The whiteness, water-holding capacity, storage modulus (G') texture MPGs significantly improved by adding 1%-2% (P < 0.05). Meanwhile, Raman spectr...
