Jul 10, 2023 (Nanowerk News) Phase change memory is a type of nonvolatile memory that harnesses a phase change material's (PCM) ability to shift from an amorphous state, i.e., where atoms are disorganized, to a crystalline state, i.e., where atoms are tightly packed close together. This change produces a reversible...

Photonic time crystals could open the door to a new branch of optics
Jul 07, 2023 (Nanowerk News) Refractive index - the ratio of the speed of electromagnetic radiation in a medium to its speed in a vacuum - can be modulated fast enough to generate photonic time crystals (PTCs) in the near-visible part of the spectrum, a new study published in the...
AI learns the language of molecules to predict their properties
Jul 07, 2023 (Nanowerk News) Discovering new materials and drugs typically involves a manual, trial-and-error process that can take decades and cost millions of dollars. To streamline this process, scientists often use machine learning to predict molecular properties and narrow down the molecules they need to synthesize and test in...
Laser pulse creates exotic order in quantum material
Jul 07, 2023 (Nanowerk News) Water flows, ice is rigid – this clear difference between the liquid and solid state of substances is part of our everyday experience. It follows from the very regular arrangement of atoms and molecules in crystalline solids, which is lost when they melt. Less clear,...
