EPFL researchers have developed a method for accurately determining the toxicity of nanomaterials. By using optical techniques, they are able to measure the concentration of the oxidizing substances produced by a damaged cell. Furthermore, this research also offers a new way to know more about the mechanisms of oxidative stress.
Researchers have discovered a new, potentially life-saving application for polyethylene terephthalate (PET), which is widely used to make plastic bottles. They have successfully converted PET into a non-toxic biocompatible material with superior fungal killing properties.
Researchers are one step closer to an eye drop-free reality with the development of a drug-eluting contact lens designed for prolonged delivery of latanoprost, a common drug used for the treatment of glaucoma, the leading cause of irreversible blindness worldwide.
The energy needed to change the magnetic orientation of a single atom - which determines its magnetic stability and therefore its usefulness in a variety of future device applications - can be modified by varying the atom's electrical coupling to nearby metals.
Researchers have demonstrated a new low energy electron beam technique and used it to probe the nanoscale electronic properties of grain boundaries and grain interiors in cadmium telluride (CdTe) solar cells. Their results suggest that controlling material properties near the grain boundaries could provide a path for increasing the efficiency of such solar cells.
If silicon is squeezed, this affects the freedom of movement of the electrons in this material. This can promote or restrict the flow of electrical current. Compare it to a garden hose. When you stand on it, less water comes out. But strangely enough, the flow of electrons in silicon actually increases when the material is compressed.
Cyber and nanotechnologies took full focus for 26 of the Partnership for Peace Consortium's Emerging Security Challenges Working Group during a two-day workshop hosted at the Swedish National Defense College in Stockholm November 20-22.
Thailand is willing to tell it all at the Seed and Need Seminar on January 31 during nanotech 2014 at Tokyo Big Sight, Tokyo, Japan. The title of the presentation is 'Nanotechnology Development in Thailand'.
Researchers have been working on the optimization of the third-generation sequencing technique based on nanopore. They found that long chain DNA with low salt concentration is more conducive to the nanopore sequencing process.
