University Of Washington It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point. Also well known is that the solid form of many materials can have numerous phases, but it is difficult to pinpoint the temperature and pressure for the points at which three solid phases can coexist stably. Scientists now have made the first-ever accurate...

An international team of physicists has developed a method for taking ultrafast “sonograms” that can track the structural changes that take place within solid materials in trillionth-of-a-second intervals as they go through an important physical process called a phase transition. Common phase transitions include the melting of candle wax before it burns and dissolving sugar in water. They are purely structural changes that produce dramatic changes in a material´s physical...

A systematic study of phase changes in vanadium dioxide has solved a mystery that has puzzled scientists for decades, according to researchers at the Department of Energy's Oak Ridge National Laboratory. Scientists have known that vanadium dioxide exhibits several competing phases when it acts as an insulator at lower temperatures. However, the exact nature of the phase behavior has not been understood since research began on vanadium dioxide in the early 1960s. Alexander Tselev, a research...

CHAMPAIGN, Ill. -- Dietary supplements containing vanadium are used by body builders to help beef up muscles and by some diabetic people to control blood sugar. New research now suggests the naturally occurring but easily toxic element may help prepare the body to recover speedily from infections from gram-negative organisms such as E. coli. In research at the University of Illinois at Urbana-Champaign, scientists are trying to understand how recovery might be encouraged and why people with...
