A team of researchers at the University of Connecticut and the US Air Force Research Laboratory has now successfully used the electrospinning of DNA complexes to produce nanofibers that incorporate two different fluorescing dyes in such a way that energy can efficiently be transferred from one dye to the other. The color of the resulting fluorescence can be controlled by means of the ratio of the two dyes.
Einem internationalen Forscherteam ist ein Durchbruch in der Nanoelektronik gelungen: Mit einer ungeraden Anzahl an Elektronen sind Moleküle, die mit Metallelektroden im Kontakt sind, nämlich schon im niedrigen Spannungsbereich extrem leitfähig.
Virginia Tech chemistry Professor Harry C. Dorn, Emory and Henry College chemistry Professor James Duchamp, and Panos Fatouros, professor and chair of the Division of Radiation Physics and Biology at the Virginia Commonwealth University School of Medicine have co-invented a hands-off process for filling fullerenes with radio-active material.
A new Northwestern University-led study of human colon, pancreatic and lung cells is the first to report that cancer cells and their non-cancerous cell neighbors, although quite different under the microscope, share very similar structural abnormalities on the nanoscale level.
Researchers at the UCLA Henry Samueli School of Engineering and Applied Science have developed a low-cost solution processing method for CIGS-based solar cells that could provide an answer to the manufacturing issue.
One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them.
Scientists at the Swedish medical university Karolinska Institutet and Linköping University are well on the way to creating the first artificial nerve cell that can communicate specifically with nerve cells in the body using neurotransmitters.
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves.
Three proposals from Nanyang Technological University (NTU) have won up to S$30 million in research fund from the National Research Foundation following its fourth call for proposals under its Competitive Research Programme Funding Scheme.
Features in the July issue of Physics World include a close look at how physics is informing our understanding of cells and of the brain, while Paul Davies, a physicist, astrobiologist and director of BEYOND: Center for Fundamental Concepts in Science at Arizona State University, suggests there are tentative signs that life itself may have arisen as a result of physicists' long-cherished theory of quantum mechanics.
The Environmental Working Group (EWG), a United States-based non-governmental organization that works to expose threats to health and the environment, has released their 2009 Sunscreen Report. The investigators expected to recommend against the use of micronized and nano-sized zinc oxide and titanium dioxide sunscreen, but after months of research and analysis of nearly 400 peer-reviewed studies, they found themselves recommending some sunscreens that may contain nanoparticles.
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised a viable way to manipulate a single 'bit' in a quantum processor without disturbing the information stored in its neighbors
The device is an embedded microsensor capable of measuring real-time water stress in living plants. In theory, the sensor will help vintners strike the precise balance between drought and overwatering - both of which diminish the quality of wine grapes.
A century after German physicist Gustav Mie derived the math to explain why the colors in some stained glass windows look especially resplendent in the sunlight, a team of Stanford engineers has built upon his work to potentially improve a means of harvesting energy from the sun.
