| An incredible shrinking material Posted: 07 Nov 2011 01:19 PM PST They shrink when you heat 'em. Most materials expand when heated, but a few contract. Now engineers have figured out how one of these curious materials, scandium trifluoride, does the trick -- a finding, they say, that will lead to a deeper understanding of all kinds of materials.  |
| Researchers ink nanostructures with tiny 'soldering iron' Posted: 07 Nov 2011 01:02 PM PST Researchers have shed light on the role of temperature in controlling a fabrication technique for drawing surface chemical patterns as small as 20 nanometers. This technique could provide an inexpensive, fast route to growing and patterning a wide variety of materials on surfaces for the fabrication of electrical circuits and chemical sensors, or for the study of how pharmaceuticals bind to proteins and viruses.  |
| 2-D electron liquid solidifies in a magnetic field Posted: 05 Nov 2011 12:33 PM PDT Physicists have developed a theory that describes, in a unified manner, the coexistence of liquid and pinned solid phases of electrons in two dimensions under the influence of a magnetic field.  |
