Researchers successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions
Crystal symmetry is a fundamental concept in materials science, playing a crucial role in determining structure-property relationships. Typically, a crystal is a solid composed of structural units that periodically repeat in three-dimensional space,.....»»
Study reports successful synthesis of centimeter-sized single crystals
A spin liquid is a special state of matter that arises in certain magnetic materials at very low temperatures. Despite its name, it doesn't have anything to do with liquids in the everyday sense. Normally, in a magnet, these electron spins like to li.....»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Novel design approach achieves nonlinear photochromism using easy-to-synthesize rhodamine spirolactam derivatives
Photochromic compounds, which change their color when exposed to light, have been widely used as photo switches to control different properties of materials. Nonlinear photochromic compounds, characterized by a nonlinear response to the intensity of.....»»
