Researchers have developed nano-sized cantilevers whose gentle touch could help discern the workings of living cells and other soft materials in their natural, liquid environment. Used in combination with a revolutionary detection mechanism, this new imaging tool is sensitive enough to investigate soft materials without the limitations present in other cantilevers. By placing a nanowire cantilever in the focus of a laser beam and detecting the resulting light pattern, scientists at the Molecular Foundry believe atomic force microscopy can be used to non-destructively image the surface of a biological cell.
Through new collaborations totaling $6.2 million, the Department of Energy's Oak Ridge National Laboratory (ORNL) and American industry will tackle some of the most critical challenges facing lithium ion battery production.
Researchers have made an important breakthrough in the use of continuous flow microreactors to produce thin film absorbers for solar cells - an innovative technology that could significantly reduce the cost of solar energy devices and reduce material waste.
After responding to a call for proposals, the research group led by Juan Bisquert at Universitat Jaume I of Castello has won the bid for a scientific and technological research project on new types of solar cells based on nanotechnologies. The project is entitled 'Low cost nanodesigned solar cells based on semiconductor nanocrystals'.
Das Symposium 'Nanowissenschaften und Nanotechnologie' der Bayerischen Akademie der Wissenschaften am Donnerstag, 29. April 2010, stellt aktuelle Entwicklungen der Forschung und moegliche Anwendungen vor, die sich durch die Nanowissenschaften in der Informations- und Kommunikationstechnologie, der Umwelttechnik und der Medizin ergeben.
In military and security situations, a split second can make the difference between life and death, so North Carolina State University's development of new 'smart sensors' that allow for faster response times from military applications is important.
The ouroboros (ancient Greek for 'tail devourer') is a motif found in many cultures: a snake biting its own tail, it symbolizes eternity and cycles. Researchers have now constructed a molecular tail devourer, and have named this new class of compound 'ouroborand'. Their tail-biter is a molecular 'machine', which functions as a nanocontainer with a built-in switch that regulates access to the cavity.
A new biosensor developed at Purdue University can measure whether neurons are performing correctly when communicating with each other, giving researchers a tool to test the effectiveness of new epilepsy or seizure treatments.
The U.S. Department of Energy's Argonne National Laboratory will host on May 3-4 the symposium 'Research Opportunities in Electrochemical Energy Storage Beyond Lithium Ion: Computational Perspectives' to discuss advanced battery technologies for transportation, electronics and renewable energy applications.
Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy.
Florida State hired Steven Lenhert to further enhance the interdisciplinary cluster of faculty who form the Integrative NanoScience Institute (INSI) - a key part of the university's ambitious Pathways of Excellence initiative.
Showcasing its energy research initiatives for an Earth Day event on April 22 at the Pentagon, the Office of Naval Research (ONR) will highlight the microbial fuel cell, a device with the potential to revolutionize naval energy use by converting decomposed marine organisms into electricity.
A small blood lab that fits into the pocket of a jacket can quickly analyze the risk of blood clots in legs prior to a long distance flight; a sensor wristband for measuring electric smog can warn pacemaker patients of life-threatening exposure: 'Smart plastics' can turn such tools into reality.
