Geochemistry of metals and metalloids in siliceous sinter deposits: Implications for elemental partitioning into silica phases
(Elsevier, 2017)
Sinter deposits are formed by precipitation of silica from hydrothermal fluids that have reached the
surface environment. They are commonly found around hot springs and represent surface expressions of
underlying geothermal ...
Thermo-mechanical behavior of a granodiorite from the Liquine fractured geothermal system (39 degrees S) in the Southern Volcanic Zone of the Andes
(Elsevier, 2020)
Fractures and faults in granitic rocks play an important role in geothermal systems because they permit the circulation of hot fluids. However, the thermo-hydro-mechanical behavior of granitic rocks has predominantly been ...
Influencie of pretreatments on crystallinity and enzymatic hydrolysis in sugar caane residues
(2019-09-04)
This research evaluated the effect of different delignification pretreatments (enzymatic and organosolv), on the crystallinity and enzymatic hydrolysis of harvested sugar cane residues. The Crystallinity Index (CrI), the ...
Origin of holocene trachyte lavas of the Quetrupillan volcanic complex, Chile: examples of residual melts in a rejuvenated crystalline mush reservoir
(Elsevier, 2018-05-15)
The Quetrupillan Volcanic Complex (QVC) is a stratovolcano placed in the center of a NW-SE volcanic chain, between Villarrica volcano and Lanin volcano, in the Central Southern Volcanic Zone of the Andes. Its youngest ...
Characterization of phase changes during fabrication of copper alloys, crystalline and non-crystalline, prepared by mechanical alloying
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ingeniería, 2016-09-01)
The manufacture of alloys in solid state has many differences with the conventional melting (casting) process. In the case of high energy milling or mechanical alloying, phase transformations of the raw materials are ...
Influence of pretreatments on crystallinity and enzymatic hydrolysis in sugar cane residues
(Brazilian Society of Chemical Engineering, 2019)
This research evaluated the effect of different delignification pretreatments (enzymatic and organosolv), on the crystallinity and enzymatic hydrolysis of harvested sugar cane residues. The Crystallinity Index (CrI), the ...
Silicic volcanism triggered by increased denudation rates in the Quaternary Andean arc of central Chile between 33 degrees 50 '-34 degrees 30 ' S
(Elsevier, 2020)
In central Chile (33 degrees 50'-34 degrees 30'S), the Quaternary arc records a distinctive episode of silicic volcanism (SiO2 >70 wt%) that occurred during latest Pleistocene (0.1-1 Ma). This episode is recorded in several ...
Morphological raman analysis of short chain branched ethylene and propylene metallocenic copolymers
(Elsevier, 2018-05)
Spectroscopic features in the Raman spectra of semicrystalline polyolefins that characterize different phase morphologies are reported. With growing incorporation of different 1-olefins, changes in the spectra due to ...
The effect of molecular weight and hydrolysis degree of poly(vinyl alcohol)(PVA) on the thermal and mechanical properties of poly(lactic acid)/PVA blends
(Associação Brasileira de Polímeros, 2018-06)
The effect of molecular weights and hydrolysis degrees (HD) of polyvinyl alcohol (PVA) on thermal and mechanical properties and crystallinity of polylactic acid (PLA)/PVA blends was investigated. Blends were prepared by ...
Low-energy ion beam synthesis of ag endotaxial nanostructures in silicon
(Springer, 2018-06)
Coherently, embedded metal nanostructures (endotaxial) are known to have potential applications concerning the areas of plasmonics, optoelectronics and thermoelectronics. Incorporating appropriate concentrations of metal ...
