A dose of carbon nanotubes more than doubles the growth rate of plant cell cultures – workhorses in the production of everything from lifesaving medications to sweeteners to dyes and perfumes – researchers are reporting. Their study, the first to show that carbon nanotubes boost plant cell division and growth, appears in the journal ACS Nano. Mariya V. Khodakovskaya and colleagues explain that their previous research demonstrated that so-called multiwalled carbon nanotubes...

Researchers from Stanford University and the U.S. Department of Energy's SLAC National Accelerator Laboratory have created the first-ever system of "designer electrons" — exotic variants of ordinary electrons with tunable properties that may ultimately lead to new types of materials and devices. "The behavior of electrons in materials is at the heart of essentially all of today's technologies," said Hari Manoharan, associate professor of physics at Stanford and a member of SLAC's...

Researchers at Oregon State University have tapped into the extraordinary power of carbon “nanotubes” to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug...

Seoul, Feb 27, 2012 - (ACN Newswire) - Hanyang University of Korea and RIKEN of Japan, in cooperation with other Asian universities and research institutes, are launching the Asian Research Network (ARN) which aims to strengthen research and educational cooperation across Asia. Recently ARN members succeeded in producing transparent touch sensors using carbon nanotubes and ink solutions that can print electronic circuits or change colour in exposure to heat or UV radiation.The spirit of...

Researchers at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have discovered a novel way to make nanomaterials. Using computer simulations, the researchers have been able to predict that long and narrow graphene nanoribbons can be rolled into carbon nanotubes by means of twisting. The research has received funding from the Academy of Finland. The basic idea is simple and easily explained: just twist the ends of...

Discovery is designed to allow inexpensive detection of poisonous industrial gases by workers wearing small sensor chips filled with gold nanowires Researchers at the University of Pittsburgh have coaxed gold into nanowires as a way of creating an inexpensive material for detecting poisonous gases found in natural gas. Along with colleagues at the National Energy Technology Laboratory (NETL), Alexander Star, associate professor of chemistry in Pitt's Kenneth P. Dietrich School of Arts and...

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...
