By carefully tuning the chemical composition of a particular compound, researchers have created a 'topological crystalline insulator', whose bulk acts as an insulator but whose surface conducts electrical currents through a process that is related to the coupling between the motion and spin of electrons.
As semiconductor nanowires emerge as indispensable building blocks for next-generation electronic, energy conversion, and photonic devices (i.e. solar panels, lasers), better understanding how to direct nanowire growth is vital.
Researchers have discovered a new approach to the production of fuels. Their new method can be used to produce much cleaner diesel. It can quickly be scaled up for industrial use. In 5 to 10 years, we may see the first cars driven by this new clean diesel.
Research on soft condensed matter physics focuses on substances that can be easily bent or deformed, such as liquids, foams, and gels. In this case, scientists investigated the way very thin elastic sheets wrap droplets of water.
A mathematical problem underlying fundamental questions in particle and quantum physics is provably unsolvable, according to a new report. The findings are important because they show that even a perfect and complete description of the microscopic properties of a material is not enough to predict its macroscopic behavior.
Scientists have introduced a method for making an artificial muscle that is based on the hierarchical self-assembly of supramolecular muscle-like fibers. Using this technique, they were able to amplify a molecular motion up to the microscopic scale.
Researchers have developed a new three-drug delivery system for cancer treatment, especially metastatic melanoma, the deadliest form of skin cancer - and shown that the system may have particular value with cancers like this that often spread through the lymphatic system.
Light and electricity dance a complicated tango in devices like LEDs, solar cells and sensors. A new anti-reflection coating lets light through without hampering the flow of electricity, a step that could increase efficiency in such devices.
