Researchers have found a convenient way to selectively prepare germanium sulfide nanostructures, including nanosheets and nanowires, that are more active than their bulk counterparts and could open the way to lower cost and safer optoelectronics, solar energy conversion and faster computer circuitry.
Scientists have developed a new approach to how signals might be transmitted at the atomic level. This could be especially important for realising logic structures with strictly defined functions on the basis of individual atoms, which in turn could find application in transistors or diodes.
Tata Steel has formed a strategic partnership with the prominent UK research body, the Engineering and Physical Sciences Research Council (EPSRC), to develop a range of innovations that will include graphene-coated steels and next-generation sensors that can operate in extreme environments.
A pilot plant for the anaerobic digestion of organic waste is going to be used for research in the field of biogas production using wastewater, sludge and organic waste from landfills and purification plants.
Using an acoustic metadevice that can influence the acoustic space and can control any of the ways in which waves travel, engineers have demonstrated, for the first time, that it is possible to dynamically alter the geometry of a three-dimensional colloidal crystal in real time.
Physicists have pushed the frontiers of quantum technology by developing a steerable 'optical tweezers' unit that uses intense laser beams to precisely split minute clouds of ultracold atoms and to smash them together.
Scientists have managed to create artificial nanostructures that can 'bend light,' called metamaterials. But the challenge has been making enough of the material to turn invisibility cloaks into a practical reality. New work may have just cracked that barrier.
Researchers have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature.
Researchers have revealed similarities between the molecular mechanism of carbon nanotube (CNT) growth and hydrocarbon combustion. The study identifies new ways to control the growth of CNTs and increase the understanding of fuel combustion processes.
An international team of researchers found that a nanoparticle trapped with laser light temporarily violates the famous second law of thermodynamics, something that is impossible on human time and length scale.
By harnessing an electropolymerization process to produce aligned arrays of polymer nanofibers, researchers have developed a thermal interface material able to conduct heat 20 times better than the original polymer. The material can operate at up to 200 degrees Celsius.
New reveals that solar cell efficiency is based upon a delicate balance between the size and purity of the interior layers, or domains. These findings may lead to better designs and improved performance in organic solar cells.
Scientists at the Center for Nanotechnology and Nanotoxicology at Harvard School of Public Health have discovered a fast, simple, and inexpensive method to measure the effective density of engineered nanoparticles in physiological fluids, thereby making it possible to accurately determine the amount of nanomaterials that come into contact with cells and tissue in culture.
