Sol-Gel Phase Transitions In Thermoreversible Gels: Onset Of Gelation And Melting, Y. Liu, R.B. Pandey

Faculty Publications

A Monte Carlo simulation model is propsed to study the phase transition and the structural evolution of thermoreversible gels with the coexistence of phase separation and gelation processes. Our model includes the mobility of all the species and the reversibilty of bonds of the clusters formed due to cross-linking reactions. These features provide a more realistic depiction of a polymer-solvent system. We attempt to elucidate the effects of interactions, solvents, polymer fraction, etc. on the phase behaviors of the thermoreversible gel. Sol-to-gel transition is studied in detail as a function of temperature, and the related critical exponents are evaluated. Two …

Genomics: Past & Future

AT THE END OF THE ROAD in Little Cottonwood Canyon, near Salt Lake City, Alta is a place of near-mythic renown among skiers. In time it may well assume similar status among molecular geneticists. In December 1984, a conference there, co-sponsored by the U.S. Department of Energy, pondered a single question: Does modern DNA research offer a way of detecting tiny genetic mutations—and, in particular, of observing any increase in the mutation rate among the survivors of the Hiroshima and Nagasaki bombings and their descendants? In short the answer was, Not yet. But in an atmosphere of rare intellectual fertility, …

Making History: Quarks, Neutrinos, And Virtual Perfection: Interviews With Robert W. Galvin And Leon M. Lederman, Timothy J. Gilfoyle

Documents

In 1986, Leon Lederman helped establish the Illinois Mathematics and Science Academy, one of the nation's first residential secondary schools created specifically for gifted students in the sciences. "Kids hate to be different," Lederman recognizes, "and very bright kids know they're different when they're in normal schools, and they react to that differentness in many different ways. But here, they're all the same. They're all . . . academically gifted and work together and collaborate and . . . have excellent teachers. While the building was a hand-me-down from the overbuilding of schools in the early '70s, it works, and …
