There were high hopes of using carbon nanotubes, particularly for ultra-fast water transport to desalinate seawater. However, a simulation now reveals that these ultra-fast transport rates might have not been properly grounded after all. Researchers who work with experiments and computer models have been at odds over the capabilities and governing physics of the material ever since.
Scientists have succeeded in building a microscope that allows magnifying the wave function of excited electronic states of the hydrogen atom by a factor of more than twenty-thousand, leading to a situation where the nodal structure of these electronic states can be visualized on a two-dimensional detector.
A light wave oscillates perpendicular to its propagation direction - that is what students learn in school. However, scientists of the Vienna University of Technology now perform atom-physics experiments with light oscillating in the longitudinal direction.
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.
