Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking uses in the electronics and composites industry. The research, in collaboration with the US Office of Naval Research, is published in Nano Letters. Graphene is made up of a single layer of carbon atoms arranged in a hexagonal lattice. It is a promising...

Carbon nanotubes and graphene consist of just a couple of layers of carbon atoms, but they are lighter than aluminium, stronger than steel and can bend like spring-coils. Physicist Niklas Lindahl at the University of Gothenburg, Sweden, has been studying the unique properties of the materials, which in future may result in improved electronics and light, strong material. Nanotechnology could revolutionize the manufacture of new types of materials. Niklas Lindahl has studied carbon...

Wake Forest Baptist Medical Center researchers have again proven that injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second laser treatment can kill them. The results of the first effort involving kidney tumors was published in 2009, but now they´ve taken the science and directed it at breast cancer tumors, specifically the tumor initiating cancer stem cells. These stem cells are hard to kill because they don´t divide very often and...

Scientists are reporting development of a new form of buckypaper, which eliminates a major drawback of these sheets of carbon nanotubes – 50,000 times thinner than a human hair, 10 times lighter than steel, but up to 250 times stronger – with potential uses ranging from body armor to next-generation batteries. Their report appears in the journal ACS Nano. In the study, Christopher Y. Li, Ph.D., and colleagues explain that there are several ways of making buckypaper, named for...

Think of it as cooking with carbon spaghetti: A Kansas State University researcher is developing new ways to create and work with carbon nanotubes -- ultrasmall tubes that look like pieces of spaghetti or string. These carbon nanotubes -- made of graphene, an atom-thick sheet of carbon -- have the perfect ingredients for improving laser detectors and rechargeable batteries, according to research by Gurpreet Singh, assistant professor of mechanical and nuclear engineering. Singh is working...

The National Research Council said on Wednesday that in order to study the potential health hazards of nanotechnology, researchers will need to drum up an additional $24 million a year. The research council said in a study that a new federal oversight agency is also required to integrate research by private business, universities and international groups. Nanotechnology is being used in a fast-growing variety of consumer products, and involves designing and manufacturing materials on a...
