Subseafloor Cross‐Hole Tracer Experiment Reveals Hydrologic Properties, Heterogeneities, and Reactions in Slow‐Spreading Oceanic Crust

open access: yesGeochemistry, Geophysics, Geosystems, 2020
The permeability, connectivity, and reactivity of fluid reservoirs in oceanic crust are poorly constrained, yet these reservoirs are pathways for about a quarter of the Earth's heat loss, and seawater‐rock exchange within them impact ocean chemical ...

The vertical distribution of iron stable isotopes in the North Atlantic near Bermuda [PDF]

open access: yes, 2012
Seawater dissolved iron isotope ratios (δ^(56)Fe) have been measured in the North Atlantic near Bermuda. In a full-depth profile, seawater dissolved δ^(56)Fe is isotopically heavy compared to crustal values throughout the water column (δ^(56)Fe_(IRMM-014)

Antibody‐Programmable Bimetallic Nanozymes for Transcriptional Blockade Therapy in HER2/ER‐Positive Breast Cancer

open access: yesAdvanced Functional Materials, EarlyView.
Zr‐Fe MOF@Ribociclib@Herceptin (ZFRH) efficiently targets/kills Human Epidermal Growth Factor Receptor 2/Estrogen Receptor‐positive (HER2/ER+) breast cancer cells. It combats tumors by: 1) Elevating ROS, altering redox balance; 2) Inhibiting transcription; 3) Inducing pyroptosis.

The Iceland Deep Drilling Project 4.5 km deep well, IDDP-2, in the seawater-recharged Reykjanes geothermal field in SW Iceland has successfully reached its supercritical target [PDF]

open access: yesScientific Drilling, 2017
The Iceland Deep Drilling Project research well RN-15/IDDP-2 at Reykjanes, Iceland, reached its target of supercritical conditions at a depth of 4.5 km in January 2017. After only 6 days of heating, the measured bottom hole temperature was 426 °C, and

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

open access: yesGeophysical 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

Numerical simulation of hydrothermal vent‐induced circulation at Endeavour Ridge [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2005
Hydrothermal venting at Endeavour Ridge is focused at five major vent fields spaced at ∼2‐km intervals along a narrow (∼1 km wide) north‐south trending rift‐valley. A Princeton Ocean Model with an axially symmetric rift‐valley centered within a rotating, full‐depth (2400 m) stratified ocean is used to simulate the circulation and associated temperature

Novel Bioconjugate Materials: Synthesis, Characterization and Medical Applications

open access: yesAdvanced Healthcare Materials, EarlyView.
This review discusses the bioconjugation of novel materials grouped under “biological”, “hybrid” and “synthetic” categories. Medical applications ranging from cancer therapy and diagnostics to optogenetics and tissue engineering are explored, and conjugation trends are highlighted as a general guide. The review concludes with a comparison of techniques
