Scientists have taken inspiration from one of the oldest natural materials to exploit the extraordinary qualities of graphene, a material set to revolutionize fields from computers and batteries to composite materials. Published today in Nature Communications, a Monash University study led by Professor Dan Li has established, for the first time, an effective way of forming graphene, which normally exists in very thin layers, into useful three-dimensional forms by mirroring the structure of...

Semiconductor Nanoflowers Hold Promise For Energy Storage And Solar Cells

April Flowers for redOrbit.com - Your Universe Online A research team from North Carolina State University has created flower-like structures out of germanium sulfide (GeS), which is a semiconductor material. The GeS flowers have extremely thin petals, 20-30 nanometers thick, with an enormous surface area. These flowers hold promise for next-generation energy storage devices and solar cells. “Creating these GeS nanoflowers is exciting because it gives us a huge surface area in...

Less Costly Ways of Sequencing DNA Could Open New Possibilities for Disease Prevention Engineers at The University of Texas at Dallas have used advanced techniques to make the material graphene small enough to read DNA. Shrinking the size of a graphene pore to less than one nanometer — small enough to thread a DNA strand  — opens the possibility of using graphene as a low-cost tool to sequence DNA. “Sequencing DNA at a very cheap cost would enable scientists...

A pencil, containing a solid pigment core within a protective casing, is a common writing implement or art medium. Having a case keeps the pigment from breaking as well as from marking the user's hand. Pencils differ from pens because they leave marks by physical abrasion rather than staining the paper. The pigment leaves behind a trail of material that adheres to the sheet of paper or other writing surface. Cores are usually made of graphite mixed with clay to bind it. Graphite is durable...

Graphite (named by Abraham Gottlob Werner in 1789, from the Greek γραφειν: "to draw/write", for its use in pencils) is one of the allotropes of carbon. Unlike diamond, graphite is a conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. Occurrence Associated minerals include: quartz, calcite, micas, iron meteorites and tourmalines. Notable occurrences include New York and Texas in the USA, Russia, Mexico, Greenland,...
