Abrupt changes of hydrothermal activity in a lava dome detected by combined seismic and muon monitoring [PDF]
arXiv, 2018 The recent 2014 eruption of the Ontake volcano in Japan recalled that hydrothermal fields of moderately active volcanoes have an unpredictable and hazardous behavior that may endanger human beings. Steam blasts can expel devastating ejecta and create craters of several tens of meters.

Origin of life's building blocks in Carbon and Nitrogen rich surface hydrothermal vents [PDF]
arXiv, 2019 There are two dominant and contrasting classes of origin of life scenarios: those predicting that life emerged in submarine hydrothermal systems, where chemical disequilibrium can provide an energy source for nascent life; and those predicting that life emerged within subaerial environments, where UV catalysis of reactions may occur to form the ...

Electronic and Superconducting Properties of Some FeSe-based Single Crystals and Films Grown Hydrothermally [PDF]
Front. Phys. 8:586182 (2020), 2020 Our recent year's studies of the prototypal FeSe and molecule-intercalated (Li,Fe)OHFeSe superconductor systems are briefly reviewed here, with emphasis on experimental observations of the link between the superconductivity and normal-state electronic property in the single crystals and films. These samples were successfully synthesized by our recently

Synthesis optimization of Zn-Mn ferrites for magnetic fluid aplications [PDF]
arXiv, 2020 Mn-Zn ferrite nanoparticles have been subject of increasing research due to their desired properties for a wide range of applications. These properties include nanometer particle size control, tunable magnetic properties and low toxicity, providing these ferrites with the necessary requirements for cancer treatment via magnetic hyperthermia.

Development of various methods for PrF3 nanoparticles synthesis [PDF]
arXiv, 2011 The six nanosized PrF3 samples were synthesized using two different chemical reactions and different time of hydrothermal reaction. The X-ray and HRTEM experiments showed high crystallinity of synthesized samples. For all samples the particles size distribution was obtained. It was shown, that precursors of chemical reaction have influence on the shape

International Journal of Speleology, 2016 Several caves of hydrothermal origin in crystalline limestones and metasomatic silicites were investigated in the central zone of the Štiavnica stratovolcano, Štiavnické vrchy Mountains, central Slovakia. Evidence of hydrothermal origin includes irregular spherical cave morphology sculptured by ascending thermal water, occurrence of large calcite ...
