Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell.
In a new approach to understand dynamic phase transitions, a joint experimental and theoretical effort was undertaken by a team of scientists, using a novel type of quantum matter in a so-called superradiant state.
Flexible optoelectronic devices that can be produced roll-to-roll are a highly promising path to cheaper devices such as solar cells and LED lighting panels. Scientists from TREASORES project present prototype flexible solar cell modules as well as novel silver-based transparent electrodes that outperform currently used materials.
As part of a U.S. Department of Energy effort to showcase new data-handling strategies, scientists from Brookhaven National Laboratory demonstrated two pilot projects for modeling and processing large-volume data sets at the SC14 (Supercomputing 2014) conference.
A new technique to produce graphene at room temperature could help pave the way for commercially feasible graphene-based solar cells and light-emitting diodes, large-panel displays, and flexible electronics.
Scientists describe a powerful approach that uses solvated graphene frameworks as the anode material. Assembled in a lithium coin cell, the as-made electrode excelled with capacities surpassing the values of typically used graphite.
The honeycomb structure of pristine graphene is beautiful, but scientists have discovered that if the graphene naturally has a few tiny holes in it, you have a proton-selective membrane that could lead to improved fuel cells.
Scientists have discovered a high performance cathode material with great promise for use in next generation lithium-sulfur batteries that could one day be used to power mobile devices and electric cars.
Scientists have eveloped a new technology which could one day create quantum phenomena in objects far larger than any achieved so far. The team successfully suspended glass particles 400 nanometres across in a vacuum using an electric field, then used lasers to cool them to within a few degrees of absolute zero.
