Molten drop deposition and the dynamics of the molten contact line
… requires a basic understanding of how molten materials spread over cold, solid surfaces. Of varticular interest are molten drop deposition processes in which the drops arrest by solidification before they reach an equilibrium configuration on the solid. Central to this spreading process …

Oxidation kinetics of molten copper sulphide
The oxidation kinetics of molten copper sulphide were investigated by quantitative measurements and qualitative observations. Off-gas analyses for SO2 and 02 were conducted to determine the oxidation rates of approximately 200-gram samples, ofmolten 99.5% Cu2S. The molten sulphide was held in …

Spreading behavior of molten metal microdroplets
Deposition of molten microdroplets is fundamental to many emerging droplet-based manufacturing (DBM) processes. Although the spreading behavior of ordinary liquid and molten droplets has been studied extensively for years, some basic questions remain unanswered. Specifically, the fundamental …

Decommissioning considerations for molten salt type reactors
Molten salt type small modular reactors are presently being developed as an option for providing electricity and alternative energy forms. The current proposed designs do not document how decommissioning will be addressed. The decontamination activities necessary for these reactor technologies upon …
