More Great Information on High Purity:
Turning heat into power (MIT)
A team of MIT researchers has developed a way of making a high-temperature
version of a kind of materials called photonic crystals, using metals such as
tungsten or tantalum. The new materials — which can operate at temperatures up
to 1200 degrees Celsius — could find a wide variety of applications powering
portable electronic devices, spacecraft to probe deep space, and new infrared
light emitters that could be used as chemical detectors and sensors.
Compared to earlier attempts to make high-temperature photonic crystals, the
new approach is “higher performance, simpler, robust and amenable to
inexpensive large-scale production,” says Ivan Celanovic ScD ’06, senior
author of a paper describing the work in the _Proceedings of the National
Academy of Sciences_. The paper was co-authored by MIT professors John
Joannopoulos and Marin Soljačić, graduate students Yi Xiang Yeng and Walker
Chen, affiliate Michael Ghebrebrhan and former postdoc Peter Bermel.
These new high-temperature, two-dimensional photonic crystals can be
fabricated almost entirely using standard microfabrication techniques and
existing equipment for manufacturing computer chips, says Celanovic, a
research engineer at MIT’s Institute for Soldier Nanotechnologies.
While there are natural photonic crystals — such as opals, whose iridescent
colors result from a layered structure ...
why do certain industries require high purity water?
why is it that the purity of water is so important for certain industries which require them?
Trace ions in water (fluoride, etc.) can screw up sensitive reactions and biological assays.
