"Yellow Chemistry" Turns Sulfur Waste into Optical Devices
Added Nov 2, 2015 | Rate View top rated
While many scientists are hard at work on "green chemistry" projects that will benefit the environment, there are a handful of researchers at the University of Arizona who are starting a trend of their own -"yellow chemistry." That's because their main ingredient is sulfur, a yellow waste product from petroleum refining and natural gas production. With support from the National Science Foundation, chemists Jeff Pyun and Richard Glass envision using sulfur waste to make lighter, cheaper electric car batteries capable of holding four to five times the charge we've come to expect. Because of its high refractive index and excellent mid-infrared transparency, sulfur also holds potential for optical applications, such as night vision devices, thermal monitoring sensors, and medical imaging hardware.
