Science Creates Glass that's Stronger Than Steel
Another piece of Star Trek technology has become reality
thanks to researchers who have developed a new kind of malleable,
non-shattering glass that's stronger than steel. by Andy Chalk, TheEscapistMagazine.com,

01.17.2011 Any nerd worth his (or her) salt will
recall the moment at which U.S.S. Enterprise Chief Engineer Montgomery Scott
met his very first Apple Macintosh computer, a bumpy interaction that
nonetheless ultimately led to the invention of transparent aluminum, a vital
component in starship construction. But what was a convenient plot mechanism 25
years ago is non-fiction today thanks to a collaboration between the U.S.
Department of Energy's Lawrence Berkeley National Laboratory and
the California Institute of Technology. Researchers have come up with a new
type of glass that's "resilient yet malleable," bends instead of
breaking when it's subjected to stress and, most important of all, is stronger
than steel. It's actually a microalloy with metallic elements like palladium
that results in a very high "'bulk-to-shear' stiffness ratio that
counteracts the intrinsic brittleness of glassy materials." Furthermore,
by tweaking the formula used in the construction of the material, the team
believes it could make the glass even stronger. "Because of the high bulk-to-shear
modulus ratio of palladium-containing material, the energy needed to form shear
bands is much lower than the energy required to turn these shear bands into
cracks," said materials scientist Robert Ritchie, who headed the Berkeley
team. "The result is that glass undergoes extensive plasticity in response
to stress, allowing it to bend rather than crack." I have no idea what that means and
neither do you but his point, I think, is that time travel is just around the corner.
Or something like that. I suppose it's possible that it could just lead to huge
advancements in architecture, construction, automotive safety and so forth,
which is pretty cool too. On the downside, we still can't have a
conversation with our computers. One step at a time, I suppose.
