Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic devices, able to transport and switch light through circuits in a stable way. Researchers now have studied how to achieve a more stable propagation of light for future optical technologies.
Interfaces between different materials and their properties are of key importance for modern technology. Physicists have developed a new method, which allows them to have an extremely precise glance at these interfaces and to model their properties.
An international research team has used a 'thermal metamaterial' to control the emission of radiation at high temperatures, an advance that could bring devices able to efficiently harvest waste heat from power plants and factories.
Materials scientists have developed a new strategy for crafting one-dimensional nanorods from a wide range of precursor materials. Based on a cellulose backbone, the system relies on the growth of block copolymer 'arms' that help create a compartment to serve as a nanometer-scale chemical reactor. The outer blocks of the arms prevent aggregation of the nanorods.
Researchers have levitated a tiny nanodiamond particle with a laser in a vacuum chamber, using the technique for the first time to detect and measure its 'torsional vibration', an advance that could bring new types of sensors and studies in quantum mechanics.
Researchers have developed a new way to simultaneously shape and surface treat plastic components. The new method can reduce the manufacturing cost of medical devices, such as diagnostic tools for various diseases.
