Highly purified silicon represents up to 40 percent of the overall costs of conventional solar-cell arrays — so researchers have long sought to maximize power output while minimizing silicon usage. Now, a team at MIT has found a new approach that could reduce the thickness of the silicon used by more than 90 percent while still maintaining high efficiency.
Carbon nanotubes represent a significant departure from traditional silicon technologies and offer a promising path to solving the challenge of energy efficiency in computer circuits, but they aren’t without challenges. Now, engineers at Stanford have found ways around the challenges to produce the first full-wafer digital logic structures based on carbon nanotubes.
Researchers from the University of Notre Dame have engineered nanoparticles that show great promise for the treatment of multiple myeloma (MM), an incurable cancer of the plasma cells in bone marrow.
Researchers at the University of California, San Diego Jacobs School of Engineering have developed a technique that enables metallic nanocrystals to self-assemble into larger, complex materials for next-generation antennas and lenses. The metal nanocrystals are cube-shaped and, like bricks or Tetris blocks, spontaneously organize themselves into larger-scale structures with precise orientations relative to one another…
Experienced anglers know that choppy waters make for difficult fishing, so they try not to rock the boat. Thanks to a new microscopy technique, cell biology researchers can heed that same advice.
Electrified graphene a shutter for light
– phys.org
(Phys.org) — An applied electric voltage can prompt a centimeter-square slice of graphene to change and control the transmission of electromagnetic radiation with wavelengths from the terahertz to the midinfrared.
Nanotechnologists are control freaks. They want to exploit the properties of materials at the ultimate level – the atoms.
