Three-dimensional (3-D) printing or additive manufacture (AM) is a popular technique that has presently attracted tremendous attention as a promising method to revolutionize design and manufacture. Researchers have expanded ...
Scientists are excited about diamonds—not the types that adorn jewelry, but the microscopic variety that are less than the width of a human hair. These so-called "nanodiamonds" are made up almost entirely of carbon. But ...

People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. They do so whenever their elementary magnets, the magnetic spins, cannot align properly. Cesium copper chloride (Cs2CuCl4) ...
