high solid content poly (styrene-co-butyl acrylate) latex ( with 20% and 40% solid content) including high amounts of cloisite 30b (7 wt% and 10 wt%) were kinetically investigated. gravimetric method via measuring the rate of polymerization, number of particles and average number of radicals per particle was used. results showed that by increasing the solid content; the average diameter of poly...

Soft supramolecular materials are promising for the design of innovative and highly tunable adhesives. These materials are composed of polymer chains functionalized by strongly interacting moieties, sometimes called "stickers". In order to systematically investigate the effect of the presence of associative groups on the debonding properties of a supramolecular adhesive, a series of supramolecu...

The preparation of both enantiomers of a chiral compound is still a vital task in pharmaceutical and bioorganic chemistry.1 Basically, it can be achieved with the use of both enantiomers of a chiral ligand, respectively, in a catalytic asymmetric process. However, the two enantiomers of a chiral ligand are not always easily available from natural chiral sources, such as amino acids, carbohydrat...

The breakup of viscous and viscoelastic drops in the high speed airstream behind a shock wave in a shock tube was photographed with a rotating drum camera giving one photograph every 5μs. From these photographs we created movies of the fragmentation history of viscous drops of widely varying viscosity, and viscoelastic drops, at very high Weber and Reynolds numbers. Drops of the order of one mi...
