Hydrothermal processing of microalgae [PDF]
, 2013 Microalgae are regarded as a promising biomass resource for the production of biofuels and chemicals which does not compete with food production. Microalgae contain large amounts of lipids and have faster growth rates than terrestrial biomass. One of the

Metal Catalysis Acting on Nitriles in Early Earth Hydrothermal Systems
Life, 2023 Hydrothermal systems are areas in which heated fluids and organic molecules rush through basaltic material rich in metals and minerals. By studying malononitrile and acetonitrile, we examine the effects of metal and mineral nanoparticles on nitrile ...

Life, 2022 Researchers have suggested that the condensation of low-molecular-weight aldehydes under basic conditions (e.g., pH > 11) is the prebiotic reaction responsible for the abiotic formation of carbohydrates.

Boletín Geológico, 2020 The products of metasomatic alteration (e.g., carbonation) of peridotites are called listvenites. Based on a description of the outcrops in the laterite deposit at Cerro Matoso located in the NW of Colombia, the mineralogical composition confirmed by ...

Hydrothermal systems on Europa [PDF]
Geophysical Research Letters, 2005 We estimate the global hydrothermal heat transport on Europa by considering the range of heat generation resulting from tidal stresses and radiogenic heat production within Europa's rocky sub‐ocean lithosphere. We show that if factors controlling tidally generated heat on Europa are similar to those on Io, global hydrothermal heat output and its high ...

The Lassen hydrothermal system [PDF]
American Mineralogist, 2016 The active Lassen hydrothermal system includes a central vapor-dominated zone or zones beneath the Lassen highlands underlain by ~240 °C high-chloride waters that discharge at lower elevations. It is the best-exposed and largest hydrothermal system in the Cascade Range, discharging 41 ± 10 kg/s of steam (~115 MW) and 23 ± 2 kg/s of high-chloride waters

Seafloor hydrothermal systems [PDF]
Journal of Geophysical Research: Solid Earth, 1995 The discovery of seafloor hydrothermal systems approximately two decades ago has led to a major reassessment of the Earth's thermal and geochemical budgets and has revolutionized our understanding of biological processes. This review traces the development of the study of seafloor hydrothermal systems from the indirect evidence provided by conductive ...

Recent high-resolution mapping of Guaymas hydrothermal fields (Southern Trough)
BSGF - Earth Sciences Bulletin, 2018 Insights into the factors controlling fluid circulation through the crust and the nature of fluid venting at the seafloor are first steps in understanding their effect on ocean properties and climate change.
