Iron single crystal growth from a lithium-rich melt [PDF]
, 2018 \alpha-Fe single crystals of rhombic dodecahedral habit were grown from a melt of Li$_{84}$N$_{12}$Fe$_{\sim 3}$. Crystals of several millimeter along a side form at temperatures around $T \approx 800^\circ$C.

Tracking Crystal‐Melt Segregation and Accumulation in the Intermediate Magma Reservoir
Geophysical Research Letters, 2023 The genesis of intermediate intrusions is highly controversial, and one of the hot topics is whether they represent frozen melts or cumulates in the evolution of magmatic systems. Distinguishing accumulation from crystallization melt differentiated along

Melt extraction from partially molten peridotites
Geochemistry, Geophysics, Geosystems, 2003 We measured the rate of melt extraction from partially molten olivine aggregates into a porous reservoir as a function of melt content (ϕ), melt viscosity, grain size, and pressure difference. Samples were prepared using mixtures of olivine and either lithium silicate, MORB glass, or albite glass to obtain a range in melt viscosities.

The Significance of Multiple Saturation Points in the Context of Polybaric Near-fractional Melting [PDF]
, 2004 Experimental petrologists have successfully located basaltic liquid compositions parental to mid-ocean ridge basalt that are, within experimental resolution, multiply saturated with three-phase harzburgite or four-phase lherzolite assemblages on their ...

Evaluation of the effect of TiC precipitates on the hydrogen trapping capacity of Fe-C-Ti alloys [PDF]
, 2014 The present work evaluates the hydrogen trapping behavior of different laboratory cast generic Fe-C-Ti martensitic alloys. Titanium carbides were precipitated in the materials by well-designed heat treatments.

Electrochemical study of the Eu(III)/Eu(II) system in molten fluoride media [PDF]
, 2009 The electrochemical behaviour of the Eu(III)/Eu(II) system was examined in the molten eutectic LiF-CaF2 on a molybdenum electrode, using cyclic voltammetry, square-wave voltammetry and chronopotentiometry. It was observed that EuF3 is partly reduced into

Influence of Lithology on Reactive Melt Flow Channelization
Geochemistry, Geophysics, Geosystems, 2020 To investigate channelization during migration of a reactive melt, we performed a series of Darcy‐type experiments in which an alkali basalt infiltrated partially molten harzburgites and lherzolites at a confining pressure of 300 MPa, temperatures of ...

Nylon 46-polytetramethylene oxide segmented block copolymers [PDF]
, 1988 Block copolymers were synthesized from amine-terminated polytetramethylene oxide (PMTO) (Mw 800 and 1130) and polyamide 4,6 salt. First prepolymers were prepared at 200–210°C in the presence of a solvent (pyrrolidone).

Accessory Mineral Eu Anomalies in Suprasolidus Rocks: Beyond Feldspar
Geochemistry, Geophysics, Geosystems, 2020 Accessory mineral Eu anomalies (Eu/Eu*) are routinely measured to infer changes in the amount of feldspar over time, allowing accessory mineral U‐Pb dates to be linked to the progressive crystallization of igneous and metamorphic rocks and, by extension,

STUDYING GLACIAL MELT PROCESSES USING SUB-CENTIMETER DEM EXTRACTION AND DIGITAL CLOSE-RANGE PHOTOGRAMMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Glaciers are sensitive to climatic variation and a particular developing area of investigation is in the field of "cryoconite”, referring to dustlike residues which form on the glacier surface.
