Deep-Sea Hydrothermal Vent Fauna: Evolution, Dispersal, Succession and Biogeography [PDF]

open access: yes, 2009
Since their discovery in 1977, the ecological communities found at deep-sea hydrothermal vents have provided many surprises about life on Earth in extreme conditions and continue to instill much curiosity in scientists that study their systems as well as

Sclerite formation in the hydrothermal-vent “scaly-foot” gastropod — possible control of iron sulfide biomineralization by the animal [PDF]

open access: yes, 2006
A gastropod from a deep-sea hydrothermal field at the Rodriguez triple junction, Indian Ocean, has scale-shaped structures, called sclerites, mineralized with iron sulfides on its foot.

Enhanced Hydrogen Evolution Reaction Performance of Ni‐Doped MoS2 with 1T Structure for Alkaline Water Electrolyzer: Introduction of 1T Phase and Morphological Optimization Through Co‐Sputtering Technique

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrogen evolution reaction activity of Ni‐doped MoS2 is enhanced by optimizing sputtering parameters in co‐sputtering. Sputtering power controls morphology and Ni doping which promotes 1T yield and activates basal planes. Sputtering time changes 1T yield regardless of Ni ratio.

Overview of hydrogen production processes: Health and environmental impact

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Hydrogen is traditionally regarded as a cornerstone in the path to a sustainable energy economy. However, there are substantial differences in the inclusion of environmental and health effects across the hydrogen production pathways, due to different feedstocks, technologies, and byproduct emissions.

Radiocarbon and Stable Carbon Isotope Constraints on the Propagation of Vent CO2 to Fluid in the Acidic Kueishantao Shallow Water Hydrothermal System

open access: yesGeochemistry, Geophysics, Geosystems, 2022
We report radiocarbon and stable carbon isotope measurements from vent gas (CO2(g)), dissolved inorganic carbon (DIC), and particulate organic carbon (POC), from two vents of the Kueishantao (KST) shallow‐water hydrothermal system, offshore northeast ...

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Development of a moored radium in situ sampler to measure annual time series

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Radium is a useful tracer of sediment‐derived materials, improving our understanding of the geochemical cycling of elements at ocean boundaries. We have developed an autonomous in situ sampler to collect time series samples of radium isotopes on mooring deployments.

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

open access: yesVIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.
