- Metal foam has a good memory
12-20-2007 · EurekAlert!
A new class of materials known as "magnetic shape-memory foams" has been developed by two research teams headed by Peter Mьllner at Boise State University and David Dunand at Northwestern University, both funded by the National Science Foundation (NSF).The foam consists of a nickel-manganese-gallium alloy whose structure resembles a piece of Swiss cheese with small voids of space between thin, curvy "struts" of material.

- Tightly packed molecules lend unexpected strength to nanothin sheet of material
07-22-2007 · EurekAlert!
Scientists at the University of Chicago and Argonne National Laboratory, have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness. "It's an amazing little marvel," said Heinrich Jaeger, Professor in Physics at the University of Chicago. "This is not a very fragile layer, but rather a robust, resilient membrane."

- Quantum effects make the difference
03-02-2007 · EurekAlert!
The atomic constituents of matter are never still, even at absolute zero (-273.15 degrees Celsius). This consequence of quantum mechanics can result in continuous transition between different material states. Physicists at the Max Planck Institute for Chemical Physics of Solids have studied this phenomenon using ytterbium, rhodium and silicon at very low temperatures under the varying influence of a magnetic field.

- What light from yonder neutron breaks?
12-20-2006 · EurekAlert!
Researchers from the National Institute of Standards and Technology (NIST) and four universities have made the first experimental observation of rare particles of light emitted during the radioactive decay of the neutron, a key building block of matter. This work confirms theoretical predictions of this type of decay of the neutron and sets the stage for a new class of tests of basic theories in particle physics.
