A new form of paper with the built-in ability to fight disease-causing bacteria could have applications that range from anti-bacterial bandages to food packaging that keeps food fresher longer to shoes that ward off foot odor.
Scientists report how they have managed for the first time to grow graphene ribbons that are just a few nanometres wide using a simple surface-based chemical method. Graphene ribbons are considered to be hot candidates for future electronics applications as their properties can be adjusted through width and edge shape.
Researchers came up with a process simple enough to be achievable with a nine-volt battery. The researchers apply an electrical charge to the nanostructures during the manufacturing process, charging each tiny wire and making it repel its neighbor.
ETH Zurich researchers have built a transistor whose crucial element is a carbon nano-tube, suspended between two contacts, with outstanding electronic properties. A novel fabrication approach allowed the scientists to construct a transistor with no gate hysteresis. This opens up new ways to manufacture nano-sensors and components that consume particularly little energy.
Scientists from the Hebrew University of Jerusalem have succeeded in showing how it is possible to greatly expand the memory capacity of future computers through the use of memory units based on silica nanoparticles combined with protein molecules obtained from the poplar tree.
The quest to come up with an artificial system organised like the biological nervous system promises to drive the future of humanoid robots and pave the way for a generation of supercomputers that can perform highly complex decision-making for gaming and defense technologies.
The effort to interest young women in the fields of science and technology received a boost on July 20 through a partnership between the College of Nanoscale Science and Engineering (CNSE) of the University at Albany and the Children's Museum of Science and Technology (CMOST) that showcased the exciting world of nanotechnology.
More than 70 users of ZEISS electron and ion microscopes from all over the world have already submitted their nano masterpieces to the first ever Carl Zeiss Nano Image Contest. The current voting record of the overall competition is held by Peter Nirmalraj from Trinity College Dublin.
To serve a world bent on gaining autonomous power for wireless sensors, MicroGen Systems LLC, of Ithaca and Cornell University's Energy Materials Center (emc2) have signed a memorandum of understanding to develop 'self-charging' batteries - that use background shaking and stirring for their energy source.
Semiconductor Research Corporation (SRC), the world's leading university-research consortium for semiconductors and related technologies, the National Science Foundation (NSF) and researchers from the University of Connecticut (UConn) and Duke University have found a new way to significantly improve the screening of small delay defects (SDDs) commonly found in semiconductors.
Liverpool scientists have managed to create nanoscale knots in the laboratory by mixing together two simple starting materials - one a rigid aromatic compound and the other a more flexible amine linker.
