Molecules, 2023 Polyhydroxyalkanoates (PHAs) are natural polyesters which biodegrade in soils and oceans but have more than double the cost of comparable oil-based polymers. PHA downstreaming from its biomass represents 50% of its overall cost.

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.

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

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]
, 2011 The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

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 ...

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

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.
