For the first time, scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space. The easy-to-build lens could lead to improved photolithography, nanoscale manipulation and manufacturing, and even high-resolution three-dimensional imaging, as well as a number of as-yet-unimagined applications in a diverse range of fields.
Nano-sized needles developed by researchers at the Norwegian University of Science and Technology (NTNU) in Trondheim can force medicine into cells, even when the cell membranes offer resistance. The needles will make it easier to study the effects of medicines on cells.
Physicists understand perfectly well why a fridge magnet sticks to certain metallic surfaces. But there are more exotic forms of magnetism whose properties remain unclear, despite decades of intense research. An important step towards filling these gaps comes now from Tilman Esslinger and his group at the Department of Physics. The team has developed a new kind of device that uses laser beams and atoms to emulate magnetic materials.
Graphene has already come a long way towards commercialisation, despite its short history. Manufacturers are busy closing their second or third round of financing and many are installing multi-tonne production capacities across the world.
A new, natural nanomaterial, which may prove incredibly beneficial to medical bioengineers, has been discovered by the research team at Western University that successfully sequenced the spider mite genome in 2011.
In pioneering new research at Columbia University, scientists have grown high-quality crystals of molybdenum disulfide (MoS2), the world's thinnest semiconductor, and studied how these crystals stitch together at the atomic scale to form continuous sheets.
Researchers have created a new type of transparent electrode that might find uses in solar cells, flexible displays for computers and consumer electronics and future optoelectronic circuits for sensors and information processing.
Researchers have developed a new drug delivery system that allows inhalation of chemotherapeutic drugs to help treat lung cancer, and in laboratory and animal tests it appears to reduce the systemic damage done to other organs while significantly improving the treatment of lung tumors.
Researchers at North Carolina State University have developed a new technique for creating high-quality semiconductor thin films at the atomic scale - meaning the films are only one atom thick. The technique can be used to create these thin films on a large scale, sufficient to coat wafers that are two inches wide, or larger.
