An Integrated Electrochemical System for Synergistic Cathodic Nitrate Reduction and Anodic Sulfite Oxidation

open access: yesMolecules, 2023
Electrochemical reduction of nitrate has broad application prospects. However, in traditional electrochemical reduction of nitrate, the low value of oxygen produced by the anodic oxygen evolution reaction and the high overpotential limit its application.

Seawater nutrient and carbonate ion concentrations recorded as P/Ca, Ba/Ca, and U/Ca in the deep-sea coral D. dianthus [PDF]

open access: yes, 2011
As paleoceanographic archives, deep sea coral skeletons offer the potential for high temporal resolution and precise absolute dating, but have not been fully investigated for geochemical reconstructions of past ocean conditions.

European experience with seawater concrete

open access: yes, 2021
The use of seawater for concrete production is not common also in Europe now, even for the production of plain concrete exposed to a marine environment.

Investigation of Minerals Extracted during Seawater Desalination Using Two-Dimensional Correlation Spectroscopy

open access: yesMolecules, 2023
In this study, mineral components extracted during the desalination process were concentrated and dried, and then identified using energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), infrared (IR), and Raman spectroscopy.

Efficient bubble/precipitate traffic enables stable seawater reduction electrocatalysis at industrial-level current densities

open access: yesNature Communications
Seawater electroreduction is attractive for future H2 production and intermittent energy storage, which has been hindered by aggressive Mg2+/Ca2+ precipitation at cathodes and consequent poor stability.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

open access: yesAdvanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Phytoplankton induced changes of air bubble residence time in seawater [PDF]

open access: yes, 2005
Air bubbles in the ocean, naturally induced by breaking waves or artificially entrained by ships, remain in the water for different periods of time. Knowledge of the factors accounting for the differences in air bubble residence time (BRT) is essential ...

Determination of the Density of Seawater [PDF]

open access: yesNature, 1971
KREMLING has recently described1 a promising new method for the determination of the density of seawater. The agreement he demonstrates between his results and those based on the equation of state, determined by Knudsen as a function of salinity and temperature, is even better than he suggests.

Electrolyte-assisted polarization leading to enhanced charge separation and solar-to-hydrogen conversion efficiency of seawater splitting

open access: yesNature Catalysis
Photocatalytic splitting of seawater for hydrogen evolution has attracted a great deal of attention in recent years. However, the poor energy conversion efficiency and stability of photocatalysts in a salty environment have greatly hindered further ...
