A prototype system for the hydrothermal oxidation of feces

Water Research X, 2022
To ensure access to safe sanitation facilities in rural communities, cheap off-grid technologies need to be developed to substitute pit latrines and open defecation. In this study, we present a prototype system based on hydrothermal oxidation, which, under optimal conditions, converts a fecal sludge simulant almost completely to CO 2 and water ...

The Seismicity of Lipari, Aeolian Islands (Italy) From One-Month Recording of the LIPARI Array

Frontiers in Earth Science, 2021
Seismic activity in volcanic settings could be the signature of processes that include magma dynamics, hydrothermal activity and geodynamics. The main goal of this study is to analyze the seismicity of Lipari Island (Southern Tyrrhenian Sea) to ...

Tinjauan Kemungkinan Sebaran Unsur Tanah Jarang (REE) di Lingkungan Panas Bumi

Indonesian Journal on Geoscience, 2014
http://dx.doi.org/10.17014/ijog.vol4no1.20091Geothermal areas occur mainly in an environment of volcanic/magmatic arc where magma chambers play a role as heat sources. The environment is situated within the convergent plate boundaries.

From Fossil to Active Hydrothermal Outflow in the Back‐Arc of the Central Apennines (Zannone Island, Italy)

Geochemistry, Geophysics, Geosystems, 2022
Post‐orogenic back‐arc magmatism is accompanied by hydrothermal ore deposits and mineralizations derived from mantle and crustal sources. We investigate Zannone Island (ZI), back‐arc Tyrrhenian basin, Italy, to define the source(s) of mineralizing ...

Thermal remanence of the ∼0.6 kya Rangitoto volcano eruption, Auckland volcanic field (New Zealand) inferred from self-potential and CO₂ flux measurements

Volcanica
Rangitoto volcano is the most recent (⁓0.6 ka) and voluminous volcano in New Zealand's Auckland Volcanic Field (AVF). In this study, we investigate the status of its hydrothermal system using a combination of self-potential (SP) and CO2 gas flux ...

Peptide Synthesis in Early Earth Hydrothermal Systems [PDF]

Astrobiology, 2009
We report here results from experiments and thermodynamic calculations that demonstrate a rapid, temperature-enhanced synthesis of oligopeptides from the condensation of aqueous glycine. Experiments were conducted in custom-made hydrothermal reactors, and organic compounds were characterized with ultraviolet-visible procedures.
