Mathematical Model for Prediction of Biomass Ash Melting Temperature using Additives

Communications, 2014
Some types of biomass ash have low ash melting temperature which can result in various problems in combustion processes. Ash slags and sinters can avoid heat transfer in heat exchangers, which can also cause corrosion of heat transfer surfaces.

Density isobar of water and melting temperature of ice: Assessing common density functionals. [PDF]

Journal of Chemical Physics
We investigate the density isobar of water and the melting temperature of ice using six different density functionals. Machine-learning potentials are employed to ensure computational affordability.

Melting temperature of graphene [PDF]

Physical Review B, 2015
We present an approach to the melting of graphene based on nucleation theory for a first order phase transition from the two-dimensional (2D) solid to the 3D liquid via an intermediate quasi-2D liquid. The applicability of nucleation theory, supported by

Melting of micro/nanoparticles considering anisotropy of surface energy

Scientific Reports, 2021
The effect of surface energy on the melting of micro/nanoparticles is studied using the asymptotic method. The asymptotic solution of the dynamic model for micro/nanoparticle melting reveals the dependence of the particle melting temperature on the ...

Multiple Melting Temperatures in Glass-Forming Melts [PDF]

Sustainability, 2022
All materials are vitrified by fast quenching even monoatomic substances. Second melting temperatures accompanied by weak exothermic or endothermic heat are often observed at Tn+ after remelting them above the equilibrium thermodynamic melting transition at Tm.
