Five teams have been selected as finalists for Friday's (March 25) Nanotechnology New Ventures Competition, an inaugural business plan competition led by Purdue University and the University of Notre Dame with prizes totaling $57,000.
There is a big demand for flash memories that can store even more data. However, it is now necessary to use new materials and technologies to improve flash memories and researchers worldwide are trying different approaches to achieve this aim. The project REALISE has developed a material and a processing technique now ready for industrial application.
Researchers in Sweden have invented an improved pump, called an electroosmotic pump, which can be placed in a "microfluidic chip". Such chips, sometimes called "lab-on-a-chip" devices, contain miniaturized versions of the beakers and test tubes found in chemistry laboratories interconnected by tiny pipes. Rather than using moving parts, the new pump moves fluids in these pipes via an electric current. The fluids to be pumped can be biological samples such as blood, urine or saliva for medical devices.
Scientists have introduced a novel contrast agent that marks tumor cells in vitro. The dye is a phosphorescent ruthenium complex incorporated into nanoparticles of a metal-organic coordination polymer, which allows an extraordinarily high level of dye loading.
A highly sensitive sensor that combines a variety of testing means (electrochemistry, spectroscopy and selective partitioning) into one device has been developed at the University of Cincinnati. It's already been tested in a variety of settings - including testing for components in nuclear waste.
A Syracuse University chemist has developed a way to use very low frequency light waves to study the weak forces (London dispersion forces) that hold molecules together in a crystal. This fundamental research could be applied to solve critical problems in drug research, manufacturing and quality control.
Structural studies of some of nature's most efficient light-harvesting systems are lighting the way for new generations of biologically inspired solar cell devices. Researchers from Washington University in St. Louis and the Department of Energy's Oak Ridge National Laboratory used small-angle neutron scattering to analyze the structure of chlorosomes in green photosynthetic bacteria.
Building on the success of the past two years, the N.C. Office of Science and Technology will host the 2011 N.C. Nanotechnology Commercialization Conference at the UNC Charlotte Barnhardt Student Center on March 29-30. The third annual conference brings together entrepreneurs, business leaders, researchers, and investors to accelerate the commercialization of nanotechnology and drive economic development.
A recently patented adhesive made by Kansas State University researchers could become a staple in every astronaut's toolbox. The patent, "pH dependent adhesive peptides", covers an adhesive made from peptides -- a compound containing two or more amino acids that link together -- that increases in strength as moisture is removed.
Scientists at the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Centre (DKFZ) in Heidelberg in Germany have developed a method to uncover the combined effects of genes. The method should help scientists understand how different genes can amplify, cancel out or mask the effects of each other.
