Nanoparticle-induced unusual melting and solidification behaviours of metals [PDF]
Nature Communications, 2017 A material with a deep melted zone (MZ) but small heat-affected zone (HAZ) is ideal for manufacturing, but improving one zone comes at the expense of the other.

Extinction behaviour for two–dimensional inward-solidification problems [PDF]
Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2003 Summary: The problem of the inward solidification of a two-dimensional region of fluid is considered, it being assumed that the liquid is initially at its fusion temperature and that heat flows by conduction only. The resulting one-phase Stefan problem is reformulated using the Baiocchi transform and is examined using matched asymptotic expansions ...

The rainfall effect onto solidification and stabilization of heavy metal-polluted sediments [PDF]
Royal Society Open Science, 2020 Rainfall makes impacts on the process of solidification/stabilization (S/S) and the long-term safety of solidified matrix. In this study, the effect of rainfall on solidification/stabilization process was investigated by the rainfall test. The unconfined

Dependence of Solidification for Bi2Te3−xSex Alloys on Their Liquid States
Scientific Reports, 2017 The resistivity versus temperature (ρ-T) behaviours of liquid n-type Bi2Te3−x Se x (x = 0.3, 0.45 and 0.6) alloys are explored up to 1050 °C. A clear hump is observed on all ρ-T curves of the three studied Bi2Te3−x Se x melts during the heating process ...
