Meeting Reports

Two investigations of amorphous materials illustrated the value of combining both neutrons and X-rays, one of the themes of the school. In the first, Robert Hart (Indiana University) identified the role of niobium in the partial crystallization of potassium niobate tellurite glasses. In the second, Jacob Urquidi (Argonne National Laboratory, IPNS) found that amorphous ice evolved under pressure from its low-density to high-density amorphous forms through a series of intermediate metastable structures, rather than through a single first-order phase transition as earlier reported.
