Photodissociation dynamics of C6HxF(6-x) (x= 1-4) at 193 nm

Article Abstract:

Photodissociation of fluorine-substituted benzenes, including 1,3-difluorobenzene, 1,2,4-trifluorobenzene, 1,2,4,5-tetrafluorobenzene, and pentafluorobenzene, at 193 nm under collision-free conditions is examined in separate experiments using multimass ion imaging techniques. Small amounts of photofragments of C6H3F2 and C6H2F3 from 1,3-difluorobenzene and 1,2,4-trifluorobenzene, were observed.

Viscosity of polyelectrolyte solutions with oppositely charged surfactant

Article Abstract:

A report made on the rheological properties of aqueous solutions of poly(acrylic acid) and an oppositely charged surfactant, dodecyltrimethylammonium bromide (C12TAB), indicates that the solution viscosity decreases rapidly as surfactant is added. The effects of polymer molecular weight, polymer concentration, and polymer charge are studied with no added salt.
