Grim Reaper…
This map predicts how air pollution with fine particles will be in the future – according to Ulas Im’s computer simulation. The blue-colored areas show where the pollution is worst. Green is a little better, and yellow means almost no pollution.

Nano Sanitizer…
The disinfectant powder is stirred in bacteria-contaminated water (upper left). The mixture is exposed to sunlight, which rapidly kills all the bacteria (upper right). A magnet collects the metallic powder after disinfection (lower right). The powder is then reloaded into another beaker of contaminated water, and the disinfection process is repeated (lower left). (Image credit: TongContinue reading “Nano Sanitizer…”

The new composition for fluorine-containing electrolytes promises to maintain high battery charging performance for future electric vehicles even at sub-zero temperatures. (Image by Shutterstock.) Topics: Battery, Chemistry, Climate Change, Global Warming, Lithium, Materials Science Scientists developed a new and safer electrolyte for lithium-ion batteries that work as well in sub-zero conditions as it does atContinue reading “A Charge For All Seasons…”
Superconductors, 3D Disorder, Fractals…
Fractals are a never-ending pattern that you can zoom in on, and the image doesn’t change. Fractals can occur in two dimensions, like frost on a window, or in three dimensions, like the limbs of a tree. A recent discovery from Purdue University researchers has established that superconducting images, seen above in red and blue,Continue reading “Superconductors, 3D Disorder, Fractals…”
