Vapor Species over Molten S–Se Mixture

Liquid-vapor phase behavior of a symmetrical binary fluid mixture

Using Monte Carlo simulation and mean-field calculations, we study the liquid-vapor phase diagram of a square-well binary fluid mixture as a function of a parameter d measuring the relative strength of interactions between particles of dissimilar and similar species. The results reveal a rich variety of liquid-vapor coexistence behaviors as d is tuned. Specifically, we uncover critical end poin...

Vapor Phase Esterification over Sodium Acid Sulfate

Diffusion of multi-isotopic chemical species in molten silicates

Diffusion experiments in a simplified Na2O–CaO–SiO2 liquid system are used to develop a general formulation for the fractionation of Ca isotopes during liquid-phase diffusion. Although chemical diffusion is a well-studied process, the mathematical description of the effects of diffusion on the separate isotopes of a chemical element is surprisingly underdeveloped and uncertain. Kinetic theory p...

Conductivity of molten sodium chloride and its supercritical vapor in strong dc electric fields

Chemical Vapor Deposition of Large-Size Monolayer MoSe2 Crystals on Molten Glass.

We report the fast growth of high-quality millimeter-size monolayer MoSe2 crystals on molten glass using an ambient pressure CVD system. We found that the isotropic surface of molten glass suppresses nucleation events and greatly improves the growth of large crystalline domains. Triangular monolayer MoSe2 crystals with sizes reaching ∼2.5 mm, and with a room-temperature carrier mobility up to ∼...
