A research team led by a scientist from the U.S. Department of Energy’s Ames Laboratory has demonstrated for the first time that the magnetic fields of bacterial cells and magnetic nano-objects in liquid can be studied at high resolution using electron microscopy. This proof-of-principle capability allows first-hand observation of liquid environment phenomena, and has the potential to vastly increase knowledge in a number of scientific fields, including many areas of physics, nanotechnology, biofuels conversion, biomedical engineering, catalysis, batteries and pharmacology.

Getting under graphite’s skin: A recently discovered method of layering metals with the 2D material may lead to brand new properties12/15/2017
Scientists at the U.S. Department of Energy’s Ames Laboratory have discovered a new process to sheathe metal under a single layer of graphite which may lead to new and better-controlled properties for these types of materials.
The U.S. Department of Energy (DOE) released Ames Laboratory’s Performance Evaluation Report Card for FY 2017, and the results show the Laboratory improved on its FY 2016 performance and now exceeds expectations in a majority of the key performance areas measured. In addition to maintaining an A- in the key category of mission accomplishment, the Laboratory also improved its grades in two important performance areas – science and technology program management and management of facilities and infrastructure – from a B+ in 2016 to an A- in 2017. In the DOE grading system, a B+ means
Physicists at the U.S. Department of Energy’s Ames Laboratory compared similar materials and returned to a long-established rule of electron movement in their quest to explain the phenomenon of extremely large magnetoresistance (XMR), in which the application of a magnetic field to a material results in a remarkably large change in electrical resistance. It is a useful property, which could be used in the development of computers with increased processor speeds and data storage.
Researchers at the U.S. Department of Energy’s Ames Laboratory have developed germanium nanoparticles with improved photoluminescence, making them potentially better materials for solar cells and imaging probes. The research team found that by adding tin to the nanoparticle’s germanium core, its lattice structure better matched the lattice structure of the cadmium-sulfide coating which allows the particles to absorb more light.
