A novel chip-scale instrument made from carbon nanotubes may simplify absolute measurements of laser power. Developers of the unit at the National Institute of Standards and Technology (NIST) say it may prove especially useful for measuring light signals transmitted by optical fibers in telecom networks.
Researchers from Johns Hopkins and Northwestern universities have discovered that the shape of nanoparticles that move DNA through the body could make a big difference in how well such therapies work to treat cancer and other diseases. The scientists also have figured how to control these shapes.
Researchers from University of Texas at Austin, in collaboration with researchers in Taiwan and China, have developed the world's smallest semiconductor laser, invisible to the naked eye.
It could be the 21rst Century version of California Gold Rush. Researchers from the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) have cracked the code for device-ready nanoparticle self-assembly. In the bargain, the team is looking to change the game – and the economics – for large-scale nanofabrication.
NanoScienceWorks.org looks at the dynamic area of nano-semoconductors, and how these tiny devices are fundamentally changing the worlds of computing and communications. We speak with the author of Nano-Semiconductor: Devices and Technology, Dr. Krzysztof Iniewski, who manages R&D developments at Redlen Technologies, Inc., a start-up firm in British Columbia, Canada. His research interests are in VLSI circuits for medical and security applications.
Researchers at University of California at Los Angeles (UCLA) have developed a supercapacitor or electrochemical capacitor (EC) composed of an expanded network of graphene — a one-atom-thick layer of graphitic carbon. The team demonstrated excellent mechanical and electrical properties as well as exceptionally high surface area.
This month, NanoScienceWorks.org looks at how ideas and work products from nanoscience are helping to reshape the focus and conversations surrounding global sustainability. We speak with the author of Nanotechnology and Global Sustainability, Dr. Donnie Maclurcan, an Honorary Research Fellow with the Institute for Nanoscale Technology at the University of Technology, Sydney, Australia.
A team of MIT researchers has found a way of precisely controlling the width and composition of nanowires as they grow, making it possible to grow complex structures designed for particular applications.
Testing the effectiveness of new pharmaceuticals may get faster thanks to a new technique which uses quantum dots to probe the efficacy of drugs in live cells. The novel technique was developed by a team at the University of Central Florida.
Scientists at Rensselaer Polytechnic Institute have produced a roadmap that can guide scientists on how to design and build graphene-based nanostructures that can be customized for applications in electronics, photovoltaics and other areas.
