    on April 2, 2020 at 7:26 PM

    One way to change the properties of a material is to stretch it just a wee bit, so its atoms are farther apart but the bonds between them don't break. This extra distance affects the behavior of electrons, which determine whether the material is an insulator or a conductor of electricity, for […]
