Felipe MacíasMarta Camps-Arbestain, in Advances in Agronomy, 2020. Carbonation (pH 7.5–9.0): The increase in the concentration of carbonate ions leads to the saturation of the system with CaCO 3 with subsequent precipitation of CaCO 3 (equilibrium pH 8.2) and other carbonates (e.g., with Mg, Na) at higher pH values. While this is not a weathering reaction per-se, the presence of CaCO 3 in ...

The presented work describes the method of preparation of thermosensitive chitosan hydrogels using calcium β-glycerophosphate salt as the only pH neutralizing agent and supporting the crosslinking process. The presence of calcium ions instead of sodium …
2011-3-14 · 5-3 5.2 Single-Component Absorption Most absorption or stripping operations are carried out in counter current flow processes, in which the gas flow is introduced in the bottom of the column and the liquid solvent is introduced in the top of the column. The mathematical analysis for both the packed and plated columns is very similar.
The present invention is directed a multifunctional polymer capable of inhibiting both calcium carbonate and calcium phosphate scale. The multifunctional polymer contains at least one monomer unit from each of four groups: dicarboxylic acids, mono-carboxylic acids, …

The subject of rock–fluid interaction is important in cases where flow through porous media is occurring. One special case is when the fluid reacts with the porous matrix. In this case, the mass transfer and reaction rate control the dissolution pattern. This article aimed to study the interaction between an acid nanoemulsion system and a carbonate porous media.
2021-6-1 · CA catalyzes the reaction between water, calcium ions (Ca 2 +) and CO 2 to produce calcium carbonate (CaCO 3), which, as we show, self-assembles into a stable material that incorporates into the cement paste structure to fill the cracks. CA is the fastest known enzyme for this process and produces calcium carbonate at an exponential rate ...
Oxy has built a large-scale solar facility in the heart of its Permian Basin operations near Odessa, Texas. The 120-acre facility uses 174,000 solar panels to generate 16 MW of electricity, the equivalent of powering about 14,000 homes. This solar farm provides energy to power our Goldsmith oilfield operations, zeroing out the carbon footprint ...

2012-10-3 · Figure S1: Expression and native purification of GFP (28.9 kDa), GFP-perlucin (46.8 kDa) and perlucin (20.2 kDa). Cell cultures were analyzed using SDS-PAGE analysis in 1-hour intervals (t0–t4) and on the following day (t5–t6). The binding (B), washing (W), and elution steps (E1 and E2) demonstrate the success in native affinity purification of GFP-perlucin.
