high-pressure chemistry

[′hī ¦presh·ər ′kem·ə·strē]
(physical chemistry)
The study of chemical reactions and phenomena that occur at pressures exceeding 10,000 bars (a bar is nearly equivalent to a kilogram per square centimeter), mainly concerned with the properties of the solid state.

"With our new high-pressure chemistry technique, we can create low-temperature reactions in much smaller spaces and with a much smaller volume of gas," said Badding.
To do this, they used high-pressure chemistry techniques to deposit semiconducting materials directly, layer by layer, into tiny holes in optical fibers.
The technique, the first of its kind to use high-pressure chemistry for making well-developed films and wires of this particular kind of silicon semiconductor, will help scientists to make more efficient and more flexible optical fibers.
These results not only pioneer a new type of high-pressure chemistry but also have implications for geophysics.
- high-pressure chemistry began in 1954 and became a separate section about 1960.
