Not exact matches

Materials researchers at North Carolina State University have developed a technique that allows them to integrate graphene, graphene oxide (GO) and reduced graphene oxide (rGO) onto silicon substrates at room temperature by using nanosecond pulsed laser annealing.

People might purify irradiated water using a substance called graphene oxide, and they could grow food using aquaponics systems that cycle nutrients between plants and fish.

Using metal ions with three or more positive charges, researchers in Tian's laboratory bonded graphene - oxide flakes into a transparent membrane.

Further testing of the material suggested that crosslinking, or bonding, using transition metals and rare - earth metals, caused the graphene oxide to possess new semiconducting, magnetic and optical properties.

The researchers used flash - treated graphene oxide to create a crawler that moved when humidity was increased.

They now want to use the technique with Shewanella oneidensis, a bacterium that can reduce graphene oxide by removing oxygen atoms as it metabolises.

Because the process developed by Mativetsky avoids the use of harmful chemicals, high temperatures or inert gas atmospheres, his work represents a promising step towards environmentally - friendly manufacturing with graphene oxide.

By using the probe of an atomic force microscope to trigger a local chemical reaction, Jeffrey Mativetsky, assistant professor of physics at Binghamton University, and PhD student Austin Faucett showed that electrically conductive features as small as four nanometers can be patterned into individual graphene oxide sheets.

For example, by removing some of the oxygen from graphene oxide, the electrically insulating material can be rendered conductive, opening up prospects for use in flexible electronics, sensors, solar cells and biomedical devices.

They then placed the graphene oxide flakes in solution and stimulated the flakes to curl into scrolls, using two similar approaches: a low - frequency tip - sonicator, and a high - frequency custom reactor.

Stein and Amadei first used a common technique called the Hummers» method to separate graphite flakes into individual layers of graphene oxide.

Stein says graphene oxide nanoscrolls could also be used as ultralight chemical sensors, drug delivery vehicles, and hydrogen storage platforms, in addition to water filters.

For example, a conductive tip can be used to write patterns on different materials by locally oxidizing or reducing a surface, a method that has been used to create conductive channels in, for example, graphene and oxide interfaces.

Using the template, the titanium oxides form tiny crystals on the graphene sheets.

Graphene - based materials, prepared from the exfoliation of graphite oxide, are used as a model of interstellar carbon dust as they contain a relatively large amount of atomic defects, either at their edges or on their surface.
