Tiny silicon crystals caused no health problems in monkeys three months after large doses were injected, marking a step forward in the quest to bring such materials into clinics as biomedical imaging agents, according to a new study.
Working with ultrathin membranes of the semiconductor indium arsenide, a team of researchers at the Berkeley Lab has discovered a quantum unit of photon absorption that should be general to all 2D semiconductors, including compound semiconductors of the III-V family that are favored for solar films and optoelectronic devices.
Chemists have developed a new method for parallel protein analysis that is, in principle, capable of identifying hundreds or even thousands of different proteins. It could be used to detect the presence of viruses and identify their type in tiny samples.
Live beings are not the only things that can move around - it turns out that small crystals can also rotate or even jump. Scientists from United Arab Emirates and Russia have now systematically examined crystals that move when irradiated by light.
The use of plasmonic black metals could someday provide a pathway to more efficient photovoltaics to improve solar energy harvesting, according to researchers at Lawrence Livermore National Laboratory.
As part of an international team of researchers, scientists at the Helmholtz Center Berlin have observed the switching mechanism from a non-conducting to a conducting state in iron oxide (specifically, magnetite) with previously unrealized precision. This switching mechanism, which in oxides proceeds in two consecutive steps, is thousands of times faster than it is in current transistors.
Could a substance that resembles baby powder curb global carbon emissions? Wake Forest University researchers believe so, and a new Department of Energy grant worth more than $1 million will enable them and collaborators at the University of Texas at Dallas to design a novel material that could help revolutionize green engineering.
