Hydrothermal plumes and processes in Indian Ocean

, 2006
The predicted cycling of the whole ocean through hydrothermal plumes is comparable to the mixing time of the oceans (few thousand years). Hence, understanding hydrothermal plume processes is crucial if their impact on the global geochemical cycles of ...

Rare‐Earth–Functionalized Carbon Dot Hydrogels as Mechanically Robust Antibacterial Wound Dressings

Advanced Healthcare Materials, EarlyView.
The schematic depicts a dynamically cross‐linked PVA hydrogel network in which reversible borate ester bonds and hydrogen‐bonding interactions integrate lanthanum‐doped carbon dots (La‐CDs) and dipotassium glycyrrhizinate (DPG) to form a mechanically robust, multifunctional matrix.

Cody hydrothermal system [PDF]

, 1982
The hot springs of Colter's Hell are the surface manifestations of a much larger hydothermal system. That system has been studied to define its extent, maximum temperature, and mechanism of operation. The study area covers 2700 km/sup 2/ (1040 mi/sup 2/) in northwest Wyoming.

An Engineered Biomimetic Nanoreactor With Cascade Functions for Targeted and Combinatorial Therapy of Ischemic Stroke

Advanced Healthcare Materials, EarlyView.
Preparation of RVG‐modified erythrocyte membrane‐coated HMPB nanocarriers loaded with L‐arginine and NBP (RM@HPAN) and its neuroprotective mechanism. After intravenous injection, RM@HPAN achieves prolonged circulation, RVG‐29‐mediated BBB penetration, and ischemic accumulation.

Rare earth element systematics in ancient and modem hydrothermal systems

, 1998
The geochemical significance of on-axis diffuse fluids, in addition to those formed during the waning phases of hydrothermal systems and off-axis crustal ageing processes, has been investigated through a comparison of the rare earth element (REE ...

Hypolithic Photosynthesis in Hydrothermal Areas and Implications for Cryptic Oxygen Oases on Archean Continental Surfaces

Frontiers in Earth Science, 2019
Mounting geochemical evidence suggests microorganisms capable of oxygenic photosynthesis (e.g., Cyanobacteria) colonized Archean continental surfaces, driving oxidative weathering of detrital pyrites prior to the 2.5 Ga Great Oxidation Event (e.g ...

Liquid and supercritical CO2 as an organic solvent in Hadean seafloor hydrothermal systems: implications for prebiotic chemical evolution

Progress in Earth and Planetary Science, 2022
Prebiotic chemical evolution and the emergence of life in the seafloor hydrothermal systems of Hadean Earth is among the most plausible and popular hypotheses for the origin of earthly life.

Moytirra: Discovery of the first known deep-sea hydrothermal vent field on the slow-spreading Mid-Atlantic Ridge north of the Azores [PDF]

, 2013
Geological, biological, morphological, and hydrochemical data are presented for the newly discovered Moytirra vent field at 45oN. This is the only high temperature hydrothermal vent known between the Azores and Iceland, in the North Atlantic and is ...

Microbial colonization of basaltic glasses in hydrothermal organic-rich sediments at Guaymas Basin

Frontiers in Microbiology, 2013
Oceanic basalts host diverse microbial communities with various metabolisms involved in C, N, S and Fe biogeochemical cycles which may contribute to mineral and glass alteration processes at, and below the seafloor.
