By developing a process in which a chemical 'sleeve' tightly wraps itself around the nanotube, scientists managed to not only create a smooth new surface on the nanotube but also to 'clean' its underlying exterior of defects in a way that has never been accomplished before.
In a finding that may help speed the production of ultra-clean fuel cell vehicles powered by hydrogen, scientists in Michigan are reporting development of a sponge-like nanomaterial with a record-high surface area for holding gases.
Ultimately, the technique, based on manipulating parahydrogen, the fuel of the space shuttle, is expected to allow doctors to learn far more about a patient's condition from an MRI scan at lower cost while increasing the range of medical conditions that can be examined.
The power of magnetism may address a major problem facing bioengineers as they try to create new tissue -- getting human cells to not only form structures, but to stimulate the growth of blood vessels to nourish that growth.
A method for creating dispersed and chemically modified graphene sheets in a wide variety of organic solvents has been developed, opening the door to use graphene in a host of important materials and applications such as conductive films, polymer composites, ultracapacitors, batteries, paints, inks and plastic electronics.
Researchers have wrestled with creating palladium nanoparticles with enough active surface area to make catalysis efficient in fuel cells while preventing particles from clumping together during the chemical processes that convert a fuel source to electricity. Two Brown University chemists have found a way to overcome those challenges.
CTSI today announced that more than forty-five clean technology executives joined forces in Washington DC last week as part of the Clean Technology + Sustainable Industries Organization annual policy tour.
Researchers at the Commerce Department's National Institute of Standards and Technology and Cornell University have capitalized on a process for manufacturing integrated circuits at the nanometer level and used it to develop a method for engineering the first-ever nanoscale fluidic (nanofluidic) device with complex three-dimensional surfaces.
To deal with the increasing dynamism in (networked) embedded systems, IMEC launches a new research program. This program will focus on moving the management of the system's resources from the design phase to runtime software solutions.
TAPPI and Alberta Ingenuity Fund are co-sponsoring the 2009 International Conference on Nanotechnology for the Forest Products Industry, scheduled for June 23-26, 2009 in Edmonton, Alberta Canada. The theme of this year's event is 'Unlocking the Potential of Nano-Enabled Biomaterials'.
