Synthesis and characterization of glycolate precursors to MTiO3 (M = Ni2+, Co2+, Zn2+)

Journal of Asian Ceramic Societies, 2017
Novel glycolate precursors to metal titanates MTiO3 (M = Ni2+, Co2+, Zn2+) were synthesized by heating metal acetate and titanium isopropoxide in ethylene glycol up to 190 °C during distilling the water to avoid hydrolysis of precursors.

Diffuse flow environments within basalt- and sediment-based hydrothermal vent ecosystems harbor specialized microbial communities [PDF]

, 2013
Hydrothermal vents differ both in surface input and subsurface geochemistry. The effects of these differences on their microbial communities are not clear.

Dispersion and Intersection of Hydrothermal Plumes in the Manus Back-Arc Basin, Western Pacific

Geofluids, 2020
The composition of hydrothermal plumes reflects the physical and chemical characteristics of seafloor hydrothermal fluids, which in turn reflects the host rock and subseafloor reaction conditions as well as the water column processes that act to alter ...

Microdistribution of Faunal Assemblages at Deep-Sea Hydrothermal Vents in the Southern Ocean [PDF]

, 2012
Chemosynthetic primary production by microbes supports abundant faunal assemblages at deep-sea hydrothermal vents, with zonation of invertebrate species typically occurring along physico-chemical gradients.

Rates of Hydrothermal Reactions

Science, 1983
The rates of reactions of silicates and aqueous fluids follow zero-order kinetics controlled by the reacting surface area with the rate constant given by the equation: log k ≏ -2900/ T -6.85, where T is temperature and where k has the unit's ...

Hydrothermal processing of biomass and related model compounds [PDF]

, 2012
Future energy supplies, as a result of governmental policy and environmental legislation, will increasingly be borne from renewable sources. Use of biomass to provide fuels and chemicals to replace those derived from coal and oil will be crucial in ...

Probing rapid carbon fixation in fast-growing seaweed Ulva meridionalis using stable isotope 13C-labelling

Scientific Reports, 2020
The high growth rate of Ulva seaweeds makes it a potential algal biomass resource. In particular, Ulva meridionalis grows up to fourfold a day. Here, we demonstrated strong carbon fixation by U.
