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).

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…”

Albert Einstein famously dismissedContinue reading “Removing the Spookiness…”
Rate of Expansion…
A University of Minnesota Twin Cities-led team used a first-of-its-kind technique to measure the expansion rate of the Universe, providing insight that could help more accurately determine the Universe’s age and help physicists and astronomers better understand the cosmos.
