Researchers have reported a new method for the lithography-free etching of complex surface motifs with the use of biodegradable polymers and enzymes. Starting with structured microchannels, they have built an assembly for the isolation and concentration of cells from whole blood.
As a laser material, Germanium together with Silicon could form the basis for innovative computer chips in which information would be transferred partially in the form of light. This technology would revolutionise data streaming within chips and give a boost to the performance of electronics.
Researchers at the University of Pennsylvania have made an important advance in this frontier of photonics, fashioning the first all-optical photonic switch out of cadmium sulfide nanowires. Moreover, they combined these photonic switches into a logic gate, a fundamental component of computer chips that process information.
Scientists from the University of Aberdeen's Marine Biodiscovery Centre and the University of St Andrews presented their work on the components of a new type of computer chip created using molecules from a sea squirt sourced from the bottom of the Great Barrier Reef.
A new process holds promise for improving the production and capabilities of the infrared light emitting diode, or LED, for use in technologies ranging from communications to night vision devices used by the military.
A new report from the National Research Council finds that the foundation of science at the U.S. Environmental Protection Agency is strong, but the agency needs to continue to address numerous present and future challenges to maintain its science leadership and meet its expanding mandates.
The National Nanotechnology Coordination Office (NNCO) will hold a webinar on September 20 to provide an open forum to answer questions and hear suggestions related to the National Nanotechnology Initiative's (NNI) public website, Nano.gov
Named NU-109 and NU-110, the materials belong to a class of crystalline nanostructure known as metal-organic frameworks (MOFs) that are promising vessels for natural gas storage for vehicles, catalysts, and other sustainable materials chemistry.
Researchers at Aalto University have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly water-repellent surface, two water droplets rebound like billiard balls.
An international team of researchers have demonstrated a new type of light beam that propagates without spreading outwards, remaining very narrow and controlled along an unprecedented distance. This "needle beam", as the team calls it, could greatly reduce signal loss for on-chip optical systems and may eventually assist the development of a more powerful class of microprocessors.
