Physicists at the University of Zurich have developed a system that enables them to switch back and forth the adhesion and stiction (static friction) of a water drop on a solid surface. The change in voltage is expressed macroscopically in the contact angle between the drop and the surface. This effect can be attributed to the change in the surface properties on the nanometer scale.
MIT researchers have found a way to use mid-infrared lasers to turn molecules in the open air into glowing filaments of electrically charged gas, or plasma. The method could make possible remote environmental monitoring to detect chemicals with high sensitivity.
By using an innovative 3-D inkjet printing method, researchers from Chemical and Biological Engineering at the University of Sheffield have taken the biggest step yet in producing microscopic silk swimming devices that are biodegradable and harmless to a biological system.
A research team at Clarkson University reports an interesting conclusion that could have major impacts on the future of nano-manufacturing. Their analysis for a model of the process of random sequential adsorption shows that even a small imprecision in the position of the lattice landing sites can dramatically affect the density of the permanently formed deposit.
Handheld, mobile phone-based microscopes can be used in developing countries after minimal training of community laboratory technicians to diagnose intestinal parasites quickly and accurately.
Harvard researchers have created nanoscale electronic scaffolds that can be seeded with cardiac cells to produce a 'bionic' cardiac patch.
As oil producers struggle to adapt to lower prices, getting as much oil as possible out of every well has become even more important, despite concerns from nearby residents that some chemicals used to boost production may pollute underground water resources. Researchers from the University of Houston have reported the discovery of a nanotechnology-based solution that could address both issues -- achieving 15 percent tertiary oil recovery at low cost, without the large volume of chemicals used in most commercial fluids.
Researchers at The Ohio State University have found a way to create the perfect texture on plastic to let soap products flow freely out of the bottle.
With a surface resembling that of plants, solar cells improve light-harvesting and thus generate more power. Scientists at KIT reproduced the epidermal cells of rose petals that have particularly good antireflection properties and integrated the transparent replicas into an organic solar cell. This resulted in a relative efficiency gain of twelve percent. An article on this subject has been published recently in the Advanced Optical Materials journal.
A team of researchers led by Dr. Friederike J. Gruhl and Professor Andrew C. B. Cato at Karlsruhe Institute of Technology (KIT) are developing a three-dimensional model for prostate cancer research based on cryogels. The model will be used to reproduce natural processes and above all to examine the development and the progression of tumors. A current paper on this project published in the scientific journal Small (DOI: 10.1002/smll.201600683).
