41False vacuum — In quantum field theory, a false vacuum is a metastable sector of space that appears to be a perturbative vacuum, but is unstable due to instanton effects that may tunnel to a lower energy state. This tunneling can be caused by quantum… …
42Critical radius — is the minimum size that must be formed by atoms or molecules clustering together (in a gas, liquid or solid matrix) before a new phase inclusion (a bubble, a droplet, or a solid particle) is stable and begins to grow. Formation of such stable… …
43Spinodal decomposition — is a method by which a mixture of two or more materials can separate into distinct regions with different material concentrations. This method differs from nucleation in that phase separation due to spinodal decomposition occurs throughout the… …
44Microfilament — Actin cytoskeleton of mouse embryo fibroblasts, stained with Fluorescein isothiocyanate phalloidin Microfilaments ( or actin filaments) are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of all eukaryotic cells.… …
45Ostwald ripening — Basic schematic of the Ostwald ripening process Ostwald ripening is an observed phenomenon in solid solutions or liquid sols which describes the change of an inhomogeneous structure over time. In other words, over time, small crystals or sol… …

49GeSbTe — GeSbTe, or Germanium Antimony Tellurium, also known as GST, is a phase change material from the group of chalcogenide glasses, used in rewritable optical discs and phase change memory applications. Its recrystallization time is down to 20… …
50Alan Needleman — was born in 1944 in Philadelphia, PA and is currently the Florence Pirce Grant University Professor of Mechanics of Solids and Structures at Brown University in Providence, RI. Professor Needleman received his B.S. from the University of… …
