Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]
, 1985 The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

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 ...

Transient rhyolite melt extraction to produce a shallow granitic pluton. [PDF]
, 2021 Rhyolitic melt that fuels explosive eruptions often originates in the upper crust via extraction from crystal-rich sources, implying an evolutionary link between volcanism and residual plutonism.

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,

Ambient and selective synthesis of dihydro-benzimidazoquinazolines in deep eutectic melt of betaine and trichloroacetic acid [PDF]
RSC AdvancesThe deep eutectic melt of betaine and trichloroacetic acid efficiently promoted the reaction of 2-(2-aminophenyl)benzimidazole with arylaldehydes at ambient temperature, yielding selectively dihydro-benzimidazoquinazoline derivatives in fairly high ...

Utilization of Agrowaste Polymers in PVC/NBR Alloys: Tensile, Thermal, and Morphological Properties
International Journal of Chemical Engineering, 2012 Poly(vinyl chloride)/nitrile butadiene rubber (PVC/NBR) alloys were melt-mixed using a Brabender Plasticorder at 180∘C and 50 rpm rotor speed. Alloys obtained by melt mixing from PVC and NBR were formulated with wood-flour- (WF-) based olive residue, a ...

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.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
