摘要: Three long-standing problems related to the physics of water, viz., possibility vitrifying bulk water by rapid quenching, its glass transition, and supposed impossibility obtaining supercooled between 150 233 K, so-called "no man's land" phase diagram, are studied using highly sensitive technique spin probe ESR. Our results suggest that can indeed be vitrified quenching; it undergoes a transition at approximately 135 relaxation behavior this method 165 K closely follows predictions Adam-Gibbs model.
