How nanoscience will improve our health and lives in the coming years

Targeted medicine deliveries and increased energy efficiency are just two of many ways

Nanoscience research involves molecules that are only 1/100th the size of cancer cells and that have the potential to profoundly improve the quality of our health and our lives. Now nine prominent nanoscientists look ahead to what we can expect in the coming decade, and conclude that nanoscience is poised to make important contributions in many areas, including health care, electronics, energy, food and water.

Seeing in Color at the Nanoscale

Berkeley Lab scientists develop a new nanotech tool to probe solar-energy conversion

If nanoscience were television, we’d be in the 1950s. Although scientists can make and manipulate nanoscale objects with increasingly awesome control, they are limited to black-and-white imagery for examining those objects. Information about nanoscale chemistry and interactions with light—the atomic-microscopy equivalent to color—is tantalizingly out of reach to all but the most persistent researchers.

But that may all change with the introduction of a new microscopy tool from researchers at the Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) that delivers exquisite chemical details with a resolution once thought impossible. The team developed their tool to investigate solar-to-electric energy conversion at its most fundamental level, but their invention promises to reveal new worlds of data to researchers in all walks of nanoscience.

New Phenomenon in Nanodisk Magnetic Vortices

Berkeley Lab Researchers Take a Mesocale Look at Magnetic Vortex Formations

The phenomenon in ferromagnetic nanodisks of magnetic vortices – hurricanes of magnetism only a few atoms across – has generated intense interest in the high-tech community because of the potential application of these vortices in non-volatile Random Access Memory (RAM) data storage systems. New findings from scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) indicate that the road to magnetic vortex RAM might be more difficult to navigate than previously supposed, but there might be unexpected rewards as well.

In an experiment made possible by the unique X-ray beams at Berkeley Lab’s Advanced Light Source (ALS), a team of researchers led by Peter Fischer and Mi-Young Im of the Center for X-Ray Optics (CXRO), in collaboration with scientists in Japan, discovered that contrary to what was previously believed, the formation of magnetic vortices in ferromagnetic nanodisks is an asymmetric phenomenon. It is possible that this breaking of symmetry would lead to failure in a data storage device during its initialization process. (more…)
