Researchers have discovered a new phase of solid carbon, called Q-carbon, which is distinct from the known phases of graphite and diamond. They have also developed a technique for using Q-carbon to make diamond-related structures at room temperature and at ambient atmospheric pressure in air.
Researchers have demonstrated how the extraordinary properties of graphene can be exploited to create artificial structures that can be used to control and manipulate electromagnetic radiation over a wide range of wavelengths.
Scientists have introduced a new method for making transparent, dirt-repellant coatings that can be applied very quickly and easily. The coatings repel both water and oily liquids and are stable at higher pressures and temperatures.
Researchers report that doping tin selenide with sodium boosts its performance as a thermoelectric material, pushing it toward usefulness. The doped material produces a significantly greater amount of electricity than the undoped material, given the same amount of heat input.
An emerging class of atomically thin materials known as monolayer semiconductors has generated a great deal of buzz in the world of materials science. Monolayers hold promise in the development of transparent LED displays, ultra-high efficiency solar cells, photo detectors and nanoscale transistors.
Physicists have found a way to better understand the properties of manmade 'smart' materials. Their method reveals how stacked layers in such a material work together to bring the material to a higher level.
Silicon nanocones generate 200 times as much infrared luminescence as comparably sized nanocolumns when excited by visible light. Modelling and experimental results show that due to their geometry, cones are able to sustain what is referred to as whispering gallery modes at infrared wavelengths which can intensify the silicon luminescence. New applications are conceivable, including silicon-based nanolasers.
Scientists have discovered how to hide the reflective upper contact and funnel light directly to the semiconductor below. Their findings could lead to a new paradigm in the design and fabrication of solar cells.
