3-D printing with custom molecules creates low-cost mechanical sensor

Posted: 09 Feb 2015 02:13 PM PST

Imagine printing out molecules that can respond to their surroundings. Chemists teamed up with engineers who are using 3-D printers to create 3-D printed objects with new capabilities. Scientists created a bone-shaped plastic tab that turns purple under stretching, offering an easy way to record the force on an object.

Buckyballs offer environmental benefits

Treated carbon-60 molecules have the ability to recover valuable metals from liquids, including water and potential pollutants. In testing various metals, researchers found that charge and ionic radius influence how the metals bind to the hydroxylated buckyballs.

Holes in valence bands of nanodiamonds discovered: Potential catalysts for splitting water

Posted: 28 Jan 2015 09:54 AM PST

Nanodiamonds are tiny crystals only a few nanometers in size. While they possess the crystalline structure of diamonds, their properties diverge considerably from those of their big brothers, because their surfaces play a dominant role in comparison to their extremely small volumes. Suspended in aqueous solutions, they could function as taxis for active substances in biomedical applications, for example, or be used as catalysts for splitting water.
