pyUserCalc: A Revised Jupyter Notebook Calculator for Uranium‐Series Disequilibria in Basalts

Earth and Space Science, 2021
Meaningful analysis of uranium‐series isotopic disequilibria in basaltic lavas relies on the use of complex forward numerical models like dynamic melting (McKenzie, 1985, https://doi.org/10.1016/0012-821x(85)90001-9) and equilibrium porous flow ...

Melting behavior of ultrathin titanium nanowires [PDF]

, 2002
The thermal stability and melting behavior of ultrathin titanium nanowires with multi-shell cylindrical structures are studied using molecular dynamic simulation. The melting temperatures of titanium nanowires show remarkable dependence on wire sizes and

Dislocation-Mediated Melting in Superfluid Vortex Lattices

, 2008
We describe thermal melting of the two-dimensional vortex lattice in a rotating superfluid by generalizing the Halperin and Nelson theory of dislocation-mediated melting.

Why do gallium clusters have a higher melting point than the bulk? [PDF]

, 2003
Density functional molecular dynamical simulations have been performed on Ga$_{17}$ and Ga$_{13}$ clusters to understand the recently observed higher-than-bulk melting temperatures in small gallium clusters [Breaux {\em et al.}, Phys. Rev. Lett. {\bf 91},

Analysis of frozen chicken meat using differential scanning calorimetry [PDF]

Food and Feed Research, 2018
The paper analyses the effect of cooling/heating rate of chicken meat (Pectoralis major) on the crystallization temperature (Tcon, Tc, Tcend), melting temperature (Tmon, Tm, Tmend), crystallization enthalpy (ΔHc) and melting enthalpy (ΔHm).

An orbital-free molecular dynamics study of melting in K_20, K_55, K_92, K_142, Rb_55 and Cs_55 clusters

, 2001
The melting-like transition in potasium clusters K_N, with N=20, 55, 92 and 142, is studied by using an orbital-free density-functional constant-energy molecular dynamics simulation method, and compared to previous theoretical results on the melting-like
