New Pd-Based Bulk Glassy Alloys with High Glass-Forming Ability and Large Supercooled Liquid Region
With the aim of developing a new bulk glassy alloy which can be applied to biomedical applications, we examined glass-forming ability and mechanical properties of Ni-free glassy alloys in Pd50 xPtxCu30P20 system. As a result, the best glass-forming composition is located at Pd35Pt15Cu30P20, and the alloy can be formed into bulk glassy rods with diameters of up to at least 30mm by fluxed water q...
متن کاملCrystal nucleation in a supercooled liquid with glassy dynamics.
In simulations of supercooled, high-density liquid silica we study a range of temperature T in which we find both crystal nucleation as well as the characteristic dynamics of a glass forming liquid, including a breakdown of the Stokes-Einstein relation. We find that the liquid cannot be observed below a homogeneous nucleation limit (HNL) at which the liquid crystallizes faster than it can equil...
متن کاملSupercooled and glassy water: Metastable liquid(s), amorphous solid(s), and a no-man's land.
We review the recent research on supercooled and glassy water, focusing on the possible origins of its complex behavior. We stress the central role played by the strong directionality of the water-water interaction and by the competition between local energy, local entropy, and local density. In this context we discuss the phenomenon of polyamorphism (i.e., the existence of more than one disord...
متن کاملMechanically induced solid-state generation of phosphorus ylides and the solvent-free Wittig reaction.
We describe the nearly quantitative preparation of phosphorus ylides and the Wittig reaction occurring in the solid sate during high-energy mechanochemical processing. Initial insights into the details of the discovered chemical transformations indicate that high-energy mechanical processing supports the interaction of reacting centers by breaking crystallinity of the reactants and by providing...
متن کاملNew Scenario of Dynamical Heterogeneity in Supercooled Liquid and Glassy States of 2D Monatomic System.
Via analysis of spatiotemporal arrangements of atoms based on their dynamics in supercooled liquid and glassy states of a 2D monatomic system with a double-well Lennard-Jones-Gauss (LJG) interaction potential, we find a new scenario of dynamical heterogeneity. Atoms with the same or very close mobility have a tendency to aggregate into clusters. The number of atoms with high mobility (and size ...
