When you tear open a bag of potato chips or pop in a DVD, you're probably putting your hand on sputter deposition. No, don't run for the soap.
Sputter deposition is an industrial process used since the 1970s to spray -- sputter, that is -- thin films onto various backings, like the metallic coating on potato chip bags, the reflective surface on DVDs, or the electronics on computer chips.
Electronic products pollute our environment with a number of heavy metals before, during and after they're used. In the U.S. alone, an estimated 70% of heavy metals in landfill come from discarded electronics. With flat screen TVs getting bigger and cheaper every year, environmental costs continue to mount.
Scientists and engineers seek to meet three goals in the production of biofuels from non-edible sources such as microalgae: efficiency, economical production and ecological sustainability. Syracuse University's Radhakrishna Sureshkumar, professor and chair of biomedical and chemical engineering in the L.C. Smith College of Engineering and Computer Science, and SU chemical engineering Ph.D. student Satvik Wani have uncovered a process that is a promising step toward accomplishing these three goals.
In the war against infectious disease, identifying the culprit is half the battle. Now, research professor Shaopeng Wang and his colleagues from the Biodesign Institute at Arizona State University, describe a new method for visualizing individual virus particles. Their research opens the door to a more detailed understanding of these minute pathogens, and may further the study of a broad range of micro- and nanoscale phenomena.
Nanoscale simulations and theoretical research performed at the Department of Energy's Oak Ridge National Laboratory are bringing scientists closer to realizing graphene's potential in electronic applications.
A team of scientists at Rutgers University has found a material in which an electric field can control the overall magnetic properties of the material. If the magnetoelectric effect discovered by the Rutgers group can be extended to higher temperatures, it could be useful for manipulating small-scale magnetic bits in ultra high-density data storage. The research appears in the current issue of Physical Review Letters.
The generation of an electric field by the compression and expansion of solid materials is known as the piezoelectric effect, and it has a wide range of applications ranging from everyday items such as watches, motion sensors and precise positioning systems. Researchers at McGill University’s Department of Chemistry have now discovered how to control this effect in nanoscale semiconductors called “quantum dots,” enabling the development of incredibly tiny new products.
A rheological technique, used by researchers at National Nanotechnology Center (NANOTEC) in Thailand has revealed the instability of y-oryzanol-loaded solid lipid nanoparticles (SLNs) over 60 days storage at three different temperatures of 4, 25, and 40ºC.
New technologies for the diagnosis of cancer are rapidly changing the clinical practice of oncology. As scientists learn more about the molecular basis of cancer, the development of new tools capable of multiple, inexpensive biomarker measurements on small samples of clinical tissue will become essential to the success of genetically informed and personalized cancer therapies.
A normally benign protein found in the human body appears to be able – when paired with nanoparticles – to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs. The finding could lead to a new strategy for targeted cancer therapies, according to Joseph DeSimone and his colleagues at the University of North Carolina at Chapel Hill. However, Dr. DeSimone, who is also co-principal investigator of the Carolina Center of Cancer Nanotechnology Excellence, also cautioned that the result raises concerns about unanticipated "off-target" effects when designing nano-delivery agents.
