Optimization of F¯ Removal From Wastewater Utilizing Alternating Current Electrocoagulation Coupled With Sonication Using a Statistical Design Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Combining electrochemical and advanced oxidation processes (AOPs) has greatly mitigated the limitations of electrocoagulation (EC) in water treatment. This study examined the effectiveness of sonolysis (US)‐assisted alternating current (AC)–EC in reducing fluoride (F¯) from landfill leachate wastewater (LLW), with measurements of electrical ...

Horizontally forced initiation of the Izu-Bonin-Mariana subduction zone

Communications Earth & Environment
The sparsity of a direct record for the moment of subduction zone initiation has led to various models describing the infancy and evolution of modern oceanic subduction systems.

Synergistic Effect on Enhanced Oil Recovery in High Salinity Carbonate Reservoirs Using a Novel PEI‐Functionalized Carbon Nanotube Nanocomposite

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Extracting the geochemical characteristics of magmas in different global tectono-magmatic settings using sparse modeling

Frontiers in Earth Science, 2022
In this study, key geochemical features of magmas formed in eight different tectono-magmatic settings (mid-ocean ridges, oceanic islands, oceanic plateaus, continental flood basalt provinces, intra-oceanic arcs, continental arcs, island arcs, and back ...

Introduction to Geochemical Modeling

Eos, Transactions American Geophysical Union, 1995
Estimates of the composition of the mantle and the processes occurring within it require the combined application of geophysics and geochemistry. Albarede's new book provides convenient access to many of the theoretical geochemical methods developed during the last two decades, during which theoretical geochemistry developed considerably.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

The Rich Chemistry of Ionized Methanol With Sulfur Dioxide: Pathways to Prebiotic and Elusive Species in Earth's Atmosphere and Space

Chemistry – A European Journal, EarlyView.
The reaction between the methanol radical cation and sulfur dioxide is remarkably fast and forms several ionic and neutral products (HOSOH+, CH2OSO+, CH2OH+, CH2O, H2O, HSO2). The chemistry goes beyond simple proton or hydrogen transfer, revealing a close interaction between the two species, relevant to atmospheric and astrochemical environments where ...

Gibbs energy minimization thermodynamics for CO2 capture by aqueous amines: Conservation laws, concentration variables, and parameter consistency

The Canadian Journal of Chemical Engineering, EarlyView.
We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...
