Major Nanotechnology Hurdle Not So Worrisome

Abstract:
According to the classic rules of physics, substances melt at a lower temperature when their sizes decrease. But scientists at Indiana University Bloomington have found that at least one substance, gallium, breaks the rules, remaining stable as a solid at temperatures as much as 400 degrees Fahrenheit above the element's normal melting point. Their report will be published in an upcoming issue of Physical Review Letters. The discovery gives hope to some nanotechnologists and "nanocomputer" engineers, who have been worried that components will behave unpredictably at smaller sizes, possibly even melting at room temperature.
