Aqueous Solution Dispersement of Carbon Nanotubes

NASA’s Langley Research Center researchers have developed a novel method to disperse carbon nanotubes in aqueous solutions using chemical buffers. By avoiding the common use of surfactants to achieve dispersion, the researchers have provided a means to maintain biocompatibility of the carbon nanotubes, while also providing a means to functionalize the nanotube surfaces for specific biological and chemical activity. One particular example is the use of this approach to functionalize the surface with nano platinum catalysts to use as electrodes for fuel cells or biofuel cells. Additional surface functionality could provide use for biosensors or delivery of functionalized molecules for medical applications.

Crawling Robot is Powered by Moisture

Using an off-the-shelf camera flash, researchers at Jilin University, China, turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity, without the need for any external power.

‘Solar Paint’ Produces Energy from Sunlight

A team from Australia’s RMIT University created a “solar paint” that generates its own energy. The sunlight-absorbing substance absorbs and splits water atoms, resulting in hydrogen that could someday be used to power fuel cells and conventional combustion engines.

Adam Sidor, NASA Research Fellow, Georgia Institute of Technology, Atlanta, GA

Thermal Protection Systems (TPS) — heatshields — form the outer surface of spacecraft and provide protection as the vehicle plunges through planetary atmospheres. Conformal ablative materials are currently being developed to improve TPS performance. Adam Sidor is developing a fresh approach to designing and manufacturing these materials to produce larger tile sizes while reducing labor, cost, and waste.
