Exposing silicon wafers to light during chip manufacture requires special fixtures called chucks. Novel electrostatic chucks made of glass ceramics are incredibly flat. This prevents structural distortions on the exposure mask and the silicon chip.
Algae is a livid green giveaway of nutrient pollution in a lake. Scientists would love to reproduce that action in tiny particles that would turn different colors if exposed to biological weapons, food spoilage or signs of poor health in the blood. Now, University of Florida engineering researchers have tapped the working parts of cells to clear a major hurdle to creating such 'smart dust'.
Working with a nanoparticle designed to target and image glioblastoma, a form of brain cancer, investigators at the University of Washington in Seattle have found that these same nanoparticles inhibit tumor cell invasion, one of the key events that leads to the metastatic spread of cancer.
A multidisciplinary team at the Massachusetts Institute of Technology (MIT) has developed carbon nanotubes that can be used as sensors for cancer drugs and other DNA-damaging agents inside living cells.
Professor Sir Michael Pepper has been appointed to the Pender Chair of Nanoelectronics at UCL (University College of London) where he will work on joint projects between the Department of Electronic and Electrical Engineering and the London Centre for Nanotechnology.
The Institut de physique et de chimie des materiaux de Strasbourg inaugurated its new transmission electron microscope on January 9, 2009. This instrument, which will be devoted to studying matter at the atomic scale, is one of the best-performing in Europe.
The ability to stream videos online with the quality of high-end home theater systems, and to run computer programs a thousand times faster, are some of the future advances being made possible by a Penn State research team led by Tony Jun Huang, the James Henderson assistant professor of engineering science and mechanics.
Dr. Tim Wilkinson from the University of Cambridge Department of Engineering's Photonics Research Group has made an exciting breakthrough by combining liquid crystals with vertically grown carbon nanotubes to create a reconfigurable three-dimensional liquid crystal device structure.
An international team of researchers has developed a numerical modeling technique to study specific types of particles called excitons, which consist of a positively and a negatively charged electron and hole, respectively.
Scientists at the RIKEN Advanced Science Institute in Wako, and co-workers at the National Academy of Sciences of Ukraine (NASU), have shown for the first time that the Casimir force has a complex dependence on temperature.
The House Science and Technology Committee today introduced legislation that highlights the growing attention on Capitol Hill to the need to strengthen federal efforts to learn more about the potential environmental, health and safety (EHS) risks posed by engineered nanomaterials.
