Test objects to see if they're magnetic, you could even make a magnet maze. Try sorting a group of toys into metal, plastic, wood and fabric. As a twist on this we sorted Ariel's cave too! Practice squashing, stretching and pulling different materials to change their shape. Try play dough, fabric, paper, soft balls.Web

Chemists study isolated molecules (e.g., as occur in the atmosphere and in astronomical environments), solutions of molecules or ions dissolved in solvents, as well as solid, liquid, and plastic materials comprised of molecules. All such forms of molecular matter are what chemistry is about. Chemical science includes how to make molecules ...Web

GANs, on the other hand, learn data distribution for materials implicitly. Specifically, instead of approximating the likelihood of a data distribution, two neural networks (generator and discriminator) simultaneously compete and cooperate with each other in a zero-sum game, or minimax problem (Goodfellow et al., 2014).The generator …Web

This is very similar to an extrusion process. Manipulation of the fiber material, template wall chemistry, and processing parameters (e.g., concentration, pH scale, soaking times, and temperature) allows the nanofiber morphology to be controlled [211]. It is possible to make hollow nanofibers (commonly referred to as nanotubes).Web
