Researchers from Massachusetts Institute of Technology and Arizona State University are studying the mechanics of shape-shifting hydrogels: Looking for relationships between a hydrogel structure's initial shape, and the medium in which it transforms, in order to predict its final shape. The researchers report that they can now create and predict complex shapes from hydrogels.

Sooner or later, robots may have the ability to "feel." In a recently published paper, a team of researchers from the University of Pittsburgh and the Massachusetts Institute of Technology demonstrated that a nonoscillating gel can be resuscitated in a fashion similar to a medical cardiopulmonary resuscitation, paving the way for development of new applications that sense mechanical stimuli and respond chemically.

University of Leeds scientists have invented a new type of
polymer gel that can be used to manufacture cheaper lithium batteries
without
compromising performance. The technology has been licensed to the American
company Polystor Energy Corporation, which is conducting trials to
commercialize
cells for portable consumer electronics.

According
to new research from a university in Australia, the combination of two
ordinary materials – graphite and water – could produce energy storage
systems that perform on par with lithium ion batteries, but recharge in a
matter of seconds and have an almost indefinite lifespan.

Researchers at the Georgia Institute of Technology have
designed a multiple-compartment gel capsule that could be used to
simultaneously deliver drugs of different types. The researchers used a
simple
one-pot method to prepare the hydrogel capsules, which measure less than
one micron.

By
combining high pressure with high temperature, Livermore researchers
have created a
nanocyrstalline diamond aerogel that could improve the optics for
something as
big as a telescope or as small as the lenses in eyeglasses.

The
life science company Cellendes in Germany has developed synthetic
hydrogels that make it possible to culture cells in three-dimensional
environments. Their invention has fundamental advantages over other
hydrogels for three-dimensional cultivation, also on the market.

Researchers from North Carolina State Univ. have created a range of
soft,
elastic gels that change color when exposed to ultraviolet (UV)
light—and
change back when the UV light is removed or the material is heated up.
