(Phys.org) —A team of researchers at Northwestern University has found that applying antioxidants such as vitamin E to polymers can cause static charge buildup to disperse without an associated shock. In their paper published ...
We study the movement of incredibly small things. How small is small? Think smaller than "nano." Think smaller than atoms themselves. We measure the infinitesimally small shifts in the positions of atoms to electrical forces. ...
