Engineering Phase Changes in Nanoparticle Arrays

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have just taken a big step toward the goal of engineering dynamic nanomaterials whose structure and associated properties can be switched on demand. In a paper appearing in Nature Materials, they describe a way to selectively rearrange the nanoparticles in three-dimensional arrays to produce different configurations, or phases, from the same nano-components.

Shape-Shifting Plastic

Researchers from Oak Ridge National Laboratory, Washington State University and the University of Idaho have developed a process to make a thermoset that can be reshaped and reused. The new plastic is a shape-memory polymer, so named because the material can “remember” its original shape and return to it after being deformed with heat or other forces.

Nanobionics Supercharge Photosynthesis

A new process has been developed for spontaneously incorporating and assembling carbon nanotubes and oxygen-scavenging nanoparticles into chloroplasts, the part of plant cells that conduct photosynthesis. Incorporation enhanced electron flow associated with photosynthesis.

CLAIRE Brings Electron Microscopy to Soft Materials

Berkeley Lab researchers, working at the Molecular Foundry, have invented a technique called “CLAIRE” that extends the incredible resolution of electron microscopy to the non-invasive nanoscale imaging of soft matter, including biomolecules, liquids, polymers, gels and foams.

New Tool Shrinks Big Data in Biology Studies at SLAC's X-ray Laser

A team led by Stanford scientists has created software that tackles the big data problem for X-ray laser experiments at the Department of Energy’s SLAC National Accelerator Laboratory. The program allows researchers to tease out more details while using far fewer samples and less data and time. It can also be used to breathe new life into old data by reanalyzing and improving results from past experiments at the Linac Coherent Light Source (LCLS) X-ray free-electron laser, a DOE Office of Science User Facility.

Ames Laboratory Scientists Create Cheaper Magnetic Material for Cars, Wind Turbines

Cerium is a widely available and inexpensive rare-earth metal. Ames Laboratory scientists have used it to create a high-performance magnet that's similar in performance to traditional dysprosium-containing magnets and could make wind turbines less expensive to manufacture.
