| NEW METALLIC MUSCLES FLEX WITH LITTLE HEAT |
| Tiny and efficient metal muscles made of nanoscale-size platinum particles have been created by German researchers, and could one day used to develop robotic limbs. |

| COOL RUNNING SEMICONDUCTORS |
| Solid-state semiconductors don't handle heat very well. If they're operated at high power they tend to burn out. Heat poses other problems as well--the hotter the device, the greater the electrical resistance (and the lower the efficiency). |

| NEW SUPERCONDUCTING TRANSFORMER IS LIGHT AND COMPACT |
| Researchers from the Technology Foundation STW and the University of Twente, in cooperation with Smit Transformatoren and Smit Draad, have developed a prototype coil for a superconducting transformer which is not only light and compact but also energy-efficient. A keen interest has already been expressed by several companies. |
