Heat Flow and Near‐Seafloor Magnetic Anomalies Highlight Hydrothermal Circulation at Brothers Volcano Caldera, Southern Kermadec Arc, New Zealand

Geophysical Research Letters, 2019
Brothers volcano is the most hydrothermally active volcano along the Kermadec arc, with distinct hydrothermal fields located on the caldera walls and on the postcollapse volcanic cones.

Scalable, Microwave‐Enabled Synthesis of Ternary WxTi1‐xO2 and Heterostructured TiO2‐WO3‐x Colloidal Nanocrystals: Carrier Dynamics and Photocatalytic Properties

Advanced Science, EarlyView.
Two microwave‐assisted synthetic methods, specifically a one‐pot and a seeded‐growth approach, are developed within a hydroalcoholic solution for the growth of single‐phase ternary WxTi1‐xO2 and heterostructured TiO2‐WO3‐x colloidal nanocrystals. Both types of nanocrystals show significant photocatalytic activity for 4‐methoxybenzyl alcohol oxidation ...

Numerical computation of hydrothermal fluid circulation in fractured Earth structures [PDF]

Geophysical Journal International, 1998
Summary Hydrothermal fluid circulation through porous Earth materials is an important physical phenomenon occurring in both submarine and continental environments. Irregularly interconnected discrete fractures are pervasive in nearly all Earth materials, providing preferential paths for fluid flow and controlling the circulating fluid patterns. Most

Photothermal–Immunomodulatory Hydrogel Reinforced by Ti3C2/ZnAl‐LDH Nanoplatform for Eradicating MRSA and Promoting Diabetic Wound Healing

Advanced Science, EarlyView.
A NETs‐inspired Ti3C2/LDH hydrogel integrates trapping, ROS boosting, and M2‐immunomodulation for MRSA‐infected wound repair. ABSTRACT MRSA infections give rise to chronic cutaneous and advance into profound tissue invasions, including osteomyelitis and sepsis—conditions for which existing clinical interventions offer only limited efficacy. The utility

Precision‐Engineered Silver Single‐Atom Carbon Dot Nanozymes for Theranostic Management of Acute Kidney Injury

Advanced Science, EarlyView.
Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Near Vent Seismicity at the Tour Eiffel Vent Site, Lucky Strike Hydrothermal Field, Mid-Atlantic Ridge

Seismica
Secondary hydrothermal circulation is created by local entrainment of cold seawater into the shallow subseafloor by the intense discharge of high temperature fluids through focused vents at black smoker hydrothermal fields.

Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...
