Melting and Crystallization of Ice in Partially Filled Nanopores [PDF]

open access: yesThe Journal of Physical Chemistry B, 2011
We investigate the melting and formation of ice in partially filled hydrophilic and hydrophobic nanopores of 3 nm diameter using molecular dynamics simulations with the mW water model. Above the melting temperature, the partially filled nanopores contain two water phases in coexistence: a condensed liquid plug and a surface-adsorbed phase.

Topology Optimization of Lattice Support Structure for Cantilever Beams Fabricated Via Laser Powder Bed Fusion

open access: yesAdvanced Engineering Materials, EarlyView., 2023
A numerical scheme is presented to design a lattice support for metallic components additively built via laser powder bed fusion. Results show that thermal‐induced distortion can be respectively reduced by 69%, 58%, and 50% in comparison to a uniform lattice, a fully solid support, and a truss‐based lattice support.

Mineralogical Evidence for Partial Melting and Melt-Rock Interaction Processes in the Mantle Peridotites of Edessa Ophiolite (North Greece)

open access: yesMinerals, 2019
The Edessa ophiolite complex of northern Greece consists of remnants of oceanic lithosphere emplaced during the Upper Jurassic-Lower Cretaceous onto the Palaeozoic-Mesozoic continental margin of Eurasia.

Helix or Coil? Fate of a Melting Heteropolymer [PDF]

open access: yesEurophysics Letters 85 10008 (2009), 2008
We determine the probability that a partially melted heteropolymer at the melting temperature will either melt completely or return to a helix state. This system is equivalent to the splitting probability for a diffusing particle on a finite interval that moves according to the Sinai model.

Hole-initiated melting process of thin films [PDF]

open access: yes, 2022
We perform numerical and experimental studies on the melting process of thin films initiated by a small hole. The presence of a non-trivial capillary surface, namely the liquid/air interface, leads to a few counter-intuitive results: (1) The melting point is elevated if the film surface is partially wettable, even with a small contact angle.

Recrystallization and Melting of Partially Melted Stark Rubber [PDF]

open access: yesRubber Chemistry and Technology, 1967
Abstract Two specimens from a piece of stark rubber which had a melting temperature originally at 41° C were partially melted at 38° C and allowed to stand for 11 years, one at about 25° C, the other at 38° C. The first showed a continuous slow decrease in specific volume, while the second increased slowly in volume for 5 months and ...

Transition from Icosahedral to Decahedral Structure in a Coexisting Solid-Liquid Nickel Cluster [PDF]

open access: yesPhys. Rev. Lett. 95 116101 (2005), 2005
We have used molecular dynamics simulations to construct a microcanonical caloric curve for a 1415-atom Ni icosahedron. Prior to melting the Ni cluster exhibits static solid-liquid phase coexistence. Initially a partial icosahedral structure coexists with a non-wetting melt.

Partial Melting of Lower Oceanic Crust Gabbro: Constraints From Poikilitic Clinopyroxene Primocrysts

open access: yesFrontiers in Earth Science, 2018
Successive magma batches underplate, ascend, stall and erupt along spreading ridges, building the oceanic crust. It is therefore important to understand the processes and conditions under which magma differentiates at mid ocean ridges.

Activity–composition relations for the calculation of partial melting equilibria in metabasic rocks

open access: yes, 2016
A set of thermodynamic models is presented that, for the first time, allows partial melting equilibria to be calculated for metabasic rocks. The models consist of new activity–composition relations combined with end‐member thermodynamic properties from ...

Superheating and solid-liquid phase coexistence in nanoparticles with non-melting surfaces [PDF]

open access: yesPhys. Rev. Lett. 96, 256101 (2006), 2006
We present a phenomenological model of melting in nanoparticles with facets that are only partially wet by their liquid phase. We show that in this model, as the solid nanoparticle seeks to avoid coexistence with the liquid, the microcanonical melting temperature can exceed the bulk melting point, and that the onset of coexistence is a first-order ...
