The rate of solidification affects the microstructure, quality and mechanical properties of the castings. The analysis of heat transfer in centrifugal casting is very complex due to rapid solidification, rotating mould, opaque mould and high temperature. As the grain size is directly depending on the rate of solidification of the casting, based on grain size the rate of solidification of the ce...

Cool frustration. Engineering composition across a thin surface oxide layer of metal particle, and stabilizing it with appropriate ligands, leads to sharp stress that frustrates solidification. Chemical potential gradients from compositional variation ligand inductive effects all contribute stabilization metastable state. An undercooled liquid particle is formed, highlighting new paradigm in en...

Soil contamination is a major threat to the sustainability of agricultural fields and safety food production. This paper presented remediation techniques, including surface covering, encapsulation, thermal restoration, stabilization, solidification, phytoremediation, bioremediation, combined remediation. Bioremediation, which uses microorganisms break down contaminants, has gained popularity du...

The leaching concentration of copper ions from the industrial sludge that has been extracted using sulfuric acid may still exceed 15 mg/L, which is the leaching standard of the toxicity characteristic leaching procedure (TCLP) for hazardous waste in Taiwan. Therefore, the acid-extracted industrial sludge is still an important source of hazardous waste. Usually, hazardous waste in Taiwan must be...

This study reports the possibility of obtaining WPI-based meringues with small sucrose content (0–15%). The whey protein isolate (WPI) solution (20%, w/v) was whipped and added to foam at concentrations 5, 10 15%. surface tension, viscosity, zeta potential pre-foam solutions, overrun, stability their rheological properties (G?, G? tan (?)) were evaluated. To produce meringues, liquid foams soli...

Gao and Sonin (1994) have proposed a method for rapid prototyping and microfabrication by precise deposition and solidification of molten microdrops. Objects can be fabricated by a drop-on-demand, computer-controlled droplet generator. To understand the fundamentals of droplet deposition and solidification, experiments have been conducted using microcrystalline wax droplets (Schiaffino and Soni...
