Controllable Water Vapor Assisted Chemical Vapor Transport Synthesis of WS2-MoS2 Heterostructure [PDF]

open access: yes, 2019
The vapor phase synthesis of two-dimensional transition-metal dichalcogenides (MX2) and their heterostructures is often poorly reproducible and sensitive to uncontrolled environmental humidity. It was recently realized that water vapor can play important roles in the growth of MX2 by reacting with MX2 at high temperature to form volatile metal ...

Drying Rate Prediction for Droplets under Combined Convection and Infrared Radiation Drying

open access: yesChemical Engineering &Technology, EarlyView.
Combined convection and radiation drying increases process efficiency and scope. Experiments regarding the influence of convective airflow temperature and radiative power on the mass reduction rate in first‐phase drying were performed. A model was developed for the drying rate prediction in 20 µL water droplets and transferred to a polymer solution ...
