- Materials Science
Filling in the blanks
Scientists have added precision to a patterning technique called microcontact printing.
- Materials Science
Heart of the Matter: Scanning scope digs deeper into microchips
Researchers have developed a noninvasive imaging technique that lets them see deep inside a microchip.
- Materials Science
Carbon nanotubes get nosy
Researchers have demonstrated that individual nanotubes, decorated with DNA, can rapidly detect a number of gases.
- Physics
Transistor laser flaunts twin talents
A transistor that doubles as a laser can now operate at room temperature, bringing it to the verge of practical applications.
- Physics
Champion of strength is forged in mighty anvil
A new form of carbon created in an anvil and composed of microscopic needles of diamond has emerged as the strongest known material.
- Materials Science
Sun and Sand: Dirty silicon could supply solar power
Scientists have proposed a way to control the distribution of contaminants in silicon, potentially opening up the use of cheaper starting materials for making solar cells.
- Materials Science
Fog Be Gone: Nanocoating clarifies the view
Scientists have created a nanocoating that prevents fogging and reflection on glass surfaces.
- Physics
Warm Ice: Frozen water forms at room temperature
Ultrathin films of ice observed at room temperature and ordinary atmospheric pressure should be more widespread than previously thought, according to new experiments indicating that weaker-than-expected electric fields induce such freezing.
- Materials Science
Fine Fabric: New, fast way to make sheets of nanotubes
Scientists have come up with a way to efficiently produce thin, transparent sheets of carbon nanotubes that are several meters long.
- Materials Science
Nanotube carpet mimics gecko feet
Carbon nanotubes can outdo the extraordinary sticking power of a gecko's foot hairs.
- Physics
Materials scientists go flat out
By separating flakes of single-layer crystals from several ordinary materials, physicists have discovered what may be both the world's thinnest materials and a technologically promising new class of substances.
