Acid-resistant, nonenveloped viruses belonging to the enterovirus, reovirus, and adenovirus groups were readily concentrated on PE60, an insoluble cross-linked polyelectrolyte based on isobutylene maleic anhydride. Hydrolysis of PE60 by NaOH increased its capacity to adsorb viruses. Hydrogen ion levels played an important role in virus concentration; optimal pH levels for maximal virus adsorpti...
Vinylcyclopropane and bicyclopropyl C6 compounds are studied as diene precursors in the Diels-Alder reaction. Their rearrangement under different thermal and microwave conditions leads to specific isomeric hexa-, pentaor butadienes, condensed with maleic anhydride as a dienophile. Adduct stereochemistries were compared to those of previously-synthesized model compounds, and are fully characteri...
Miniemulsion polymerization technique has been used extensively for preparing small sized uniform particles of polymers, core-shell polymer particles, hybrid particles and encapsulation of liquid core. The technique has achieved limited success in the area of uniform core shell structure with liquid as core, as it requires matching of strict thermodynamic and kinetic factors. The interfacial te...
