New Form Of Carbon: Grossly Warped 'Nanographene'
2013-07-15 15:15:00

Boston College Bucking planarity, contorted sheets of graphene alter physical, optical and electronic properties of new material Chemists at Boston College and Nagoya University in Japan have synthesized the first example of a new form of carbon, the team reports in the most recent online edition of the journal Nature Chemistry. The new material consists of multiple identical pieces of grossly warped graphene, each containing exactly 80 carbon atoms joined together in a network of 26...

A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt normal function. Understanding the mechanical forces of nanotoxicity should help engineers design safer materials at the nanoscale. Researchers from Brown University have shown how tiny graphene microsheets — ultra-thin materials with a number of commercial...

Strength Of CVD Graphene Revealed In New Study
2013-05-31 14:01:24

Columbia University In a new study, published in Science May 31, 2013, Columbia Engineering researchers demonstrate that graphene, even if stitched together from many small crystalline grains, is almost as strong as graphene in its perfect crystalline form. This work resolves a contradiction between theoretical simulations, which predicted that grain boundaries can be strong, and earlier experiments, which indicated that they were much weaker than the perfect lattice. Graphene consists...

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,...

barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
