Take a material that is a focus of interest in the quest for advanced solar cells. Discover a "freshman chemistry level" technique for growing that material into high-efficiency, ultra-small lasers. The result, disclosed today (Monday, April 13) in Nature Materials, is a shortcut to lasers that are extremely efficient and able to create many colors of light.

When a scientist needs to concentrate a sample that’s in a volatile liquid—like acetone, acetonitrile, or methanol—a nitrogen evaporator can do the job. As a result, scientists use this technology in sample preparation in environmental, polymer science, quality control, and toxicology labs, plus others.

Refrigeration and air conditioning may become more efficient and environmentally friendly thanks to the patent-pending work of Louisiana State University (LSU) physicists. The team of researchers led by LSU Physics Professor Shane Stadler has discovered a breakthrough magnetocaloric material that may change the energy industry, including air conditioning and food refrigeration.
