[1] We demonstrate that deformation of partially molten ductile rocks can produce melt segregation by two-phase flow. In simple shear experiments on several melt-rock systems at high temperature and pressure, melt segregates into distinct melt-rich layers oriented 20 to the shear plane. Melt segregates in samples in which pressure gradients can develop at length scales less than the sample thic...

Lignin, a byproduct of paper and pulp industries, is a sustainable, inexpensive biomaterial with potential as composite filler. Past research on polyolefin/lignin composites made by melt processing has led to modest increases in Young’s modulus and drastic reductions in tensile strength and elongation at break relative to neat polymer. Here, green hybrids of low density polyethylene (LDPE) and ...

Solid dispersion is molecular dispersion of drug in a polymer matrix which leads to improved solubility and hence better bioavailability. Solvent evaporation technique was employed to prepare films of different combinations of polymers, plasticizer, and a modal drug sulindac to narrow down on a few polymer-plasticizer-sulindac combinations. The sulindac-polymer-plasticizer combination that was ...

[1] In this study, we use a numerical sea‐ice‐ocean model to examine what causes summertime upper ocean warming and sea ice melt during the 21st century in the Arctic Ocean. Our first question is, “What causes the ocean to warm in the Pacific Sector during the summer”?We find that about 80% of total heating over this region comes from ocean surface heat flux, with the remaining 20% originating ...

In the transition-zone water-filter hypothesis, (see main text), water is assumed essentially trapped within the transition zone because of dehydration melting of ambient upwelling at 410km and exsolution of water from slabs at 660km. The assumption that recycling of water is closed allows us to develop a simple theoretical model with which to predict various important parameters such as the me...

Tabular dunites in the Josephine peridotite of southwestern Oregon represent conduits for melt extraction from the upper mantle. The amount of melt trapped within these channels during cooling and exhumation of the peridotite massif was calculated using a mass-balance approach. These calculations suggest that no more than 0·1^0·2 vol. % melt could have been trapped within these dunites after cr...

Introduction: Impact melts resulting from craterproducing impacts on asteroids can be used to understand the collisional evolution of our solar system. Part of that analysis includes an assessment of the cooling rates of the impact melts and/or the locations where the melts are deposited. In this study, we examined LAP 04751 [1], which is an impact melt breccia that came from the H-chondrite pa...

In the present work microstructural evolution of A356 Aluminum alloy using an inclined cooling plate casting process for thixoforming feedstock production is investigated. The resultant microstructure was evaluated and compared with those of the same alloy produced by the conventional casting process, i.e. directly cast in the same mold without using an inclined cooling plate. It was found that...

Front Cover: In article number 2000265 by Paul D. Dalton, Hans-Werner Schmidt, and co-workers, (AB)n copolymers composed of hydrophilic poly(ethylene glycol)-based segments bisurea segments, acting as physical crosslinks, are tailored for different melt-processing technologies. Defi ned 3D constructs can be made from extrusion-based printing melt electrowriting while a typical nonwoven morpholo...

The impregnation of continuous carbon fibre roving with thermoplastic melt is a challenging task due to the high viscosity and surface tension melt. A new technique under development utilizing ultrasonic oscillations within which encloses roving, achieve impregnation. Despite processing being very efficient, specific conditions created in have never been studied before. This study investigated ...
