New Method For Manufacturing Graphene
2012-06-20 12:57:06

Considered by many as the most promising material of the future, graphene still remains an expensive and hard-to-fabricate substance. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw, and the Interdisciplinary Research Institute in Lille developed a low cost method for manufacturing multilayered graphene sheets. The new method does not require any specialized equipment and can be implemented in any laboratory. A low cost method for producing...

A team of U.S. and Chinese researchers are claiming that they have developed a new type of graphene that could prevent laptops and other electronic devices from overheating. Mechanical and electrical engineers from the University of Texas at Austin and the University of California - Riverside, along with colleagues from the University of Texas at Dallas and Xiamen University in China, have demonstrated that the thermal properties of isotopically engineered graphene far surpassed those of...

Hydrogen, the most common element in the universe, is normally an insulating gas, but at high pressures it may turn into a superconductor. Now, scientists at the Carnegie Institution in Washington D.C., US, have discovered a hydrogen-based compound that could be helpful in the search for metallic and superconducting forms of hydrogen. The results are reported in Physical Review Letters and highlighted in the August 3rd issue of APS's on-line journal Physics (physics.aps.org).Hydrogen is the...

By Peng, J Z Yang, X Z; Zhou, F C; Gray, M F According to the average lattice and atom model of the empirical electron theory (EET) of solids and molecules, effects of interstitial impurities on valence electron structures (VESs) and phase transformation of Ti-Al alloys are analysed. In particular, melting points or allotropic transformation in Ti-Al phase diagram affected by interstitial impurities are calculated using the bond energy formula of the EET. It is demonstrated that because of...

Carbon cages can hold super-dense volumes of nearly metallic hydrogen HOUSTON -- Hydrogen could be a clean, abundant energy source, but it's difficult to store in bulk. In new research, materials scientists at Rice University have made the surprising discovery that tiny carbon capsules called buckyballs are so strong they can hold volumes of hydrogen nearly as dense as those at the center of Jupiter. The research appears on the March 2008 cover of the American Chemical Society's journal Nano...

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,...
