Penn researchers make first all-optical nanowire switch
Computers may be getting faster every year, but those advances in computer speed could be dwarfed if their 1s and 0s were represented by light, instead of electricity. 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.

Semiconductors grown on graphene
Researchers at the Norwegian University of Science and Technology have patented and are commercializing GaAs nanowires grown on graphene, a hybrid material with competitive properties. Semiconductors grown on graphene are expected to become the basis for new types of device systems, and could fundamentally change the semiconductor industry.

Nano-velcro clasps heavy metal molecules in its grips
Researchers have devised a simple, system based on nanoparticles, to detect mercury as well as others pollutants. This technology makes it possible to easily and inexpensively test for these substances in water and, more importantly, in the fish that we eat. This will be published in Nature Material on September 9, 2012.

Needle beam could eliminate signal loss in on-chip optics
An international, Harvard-led 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.

Wireless window sentinel
Window contacts tell users if a window is open or closed. Typically, such sensors are wire-based. Scientists working with industry partners recently developed a new system that operates without wires or batteries. It draws its power from its environment: from sunlight and ambient heat.
