Influence of chemical reaction kinetics on electrokinetic remediation modelling results [PDF]
, 2017 A numerical model describing transport of multiple species and chemical reactions during electrokinetic treatment is presented. The transport mechanisms included in the model were electromigration and electroosmosis.

The Depositional Record, EarlyView.A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

The Depositional Record, EarlyView.Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.

Anomalously cool clumped isotope temperatures in tropical lagoon carbonates
The Depositional Record, EarlyView.Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

The Depositional Record, EarlyView.The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Influence of environment and mineralogy on euendolithic microboring patterns
The Depositional Record, EarlyView.Field experiments at Little Ambergris Cay reveal that euendolithic microorganisms preferentially bore carbonate substrates based on mineralogy, sea water saturation and trace metal content. Results highlight night‐time dissolution activity and mineralogical preferences, shedding light on the ecological and evolutionary drivers of bioerosion and their ...

Adsorptive Desulfurization of Iraqi Light Naphtha Using Calcite and Modified Calcite
Iraqi Journal of Chemical and Petroleum EngineeringThis study used the adsorption method to remove sulfur compounds from light naphtha fuel by using calcite and modified calcite as adsorbents. The calcite was prepared from chicken eggshells by heating and activation methods. It was modified by mixing it
