REVERSIBLE QUINONE METHIDE ALKYLATION OF DNA
… numerous metabolism processes. Studies of QM's reversible reaction with nucleophiles of DNA are important to understand the mechanism of its biological activity. Reversible alkylation of QMs can extend their lifetime under aqueous conditions. The repeated capture and release of QM from dA adduct …

Aging processes in complex systems
… with simple and complex aging properties, namely reaction diffusion systems with a power growth law, driven diffusive systems with a logarithmic growth law, and a non-equilibrium polymer network that is supposed to capture important properties of the cytoskeleton of living cells. For the reaction …

The discovery of baddeleyite (ZrO2) and chrome spinel in the basal Rooiberg Group of the 2.057 Ga Bushveld Complex, South Africa: Implications for the impact and igneous scenarios for the petrogenesis of the Rooiberg Group.
… in several impact structures as a result of the reversible reaction: ZrSiO4 = ZrO2 + SiO2 at ~1686°C. Therefore, the presence of zircon and baddeleyite in the Basal Rhyolite provides a test for an impact origin of the Basal Rhyolite. Electron microprobe and transmission electron microscope …

Nanoemulsion-like Polymersomes for Nanoreactors
… ionic liquids (ILs) are of great interest as reaction media, with the possibility of replacing organic solvents. However, the implementation ILs is limited by their high viscosity and cost. Phase transfer of IL-filled polymer vesicles (polymersomes) from the IL phase to water produces a very …

Development of solvent for CO2 capture for utilization in concrete and storage in geological formations
… were loaded with CO2 and used for carbonation reactions. The presence of CaCO3, the main product formed when CO2 reacts with concrete, was confirmed by XRD phase identification analysis. Also, by the TGA thermogram, the calcium carbonates in the precipitate of the K2CO3-Ca(OH)2 reaction was …

Metabolic basis for the preferential utilization of disaccharide, by the cellulose-decomposing bacterium, cellvibrio gilvus (nov. sp.)
… A cellobiose phosphorylase was demonstrated as a reversible reaction producing glucose and alpha-D-glucose-1-phosphate. Conversion of glucose-1-phosphate to glucose-6-phosphate was not obtained but fructose-6-phosphate was formed. Ground cells oxidized fructose-1,6-diphosphate and …

The Influence of Equilibrium Reactions on the Kinetics of Calcite Dissolution in Lactic Acid Solutions
… to minimize the corrosion problem and the rapid reaction rate encountered when using strong acids, such as hydrochloric acid (HCl). The reaction of an organic acid with carbonates is reversible and thermodynamically limited by the presence of reaction products. This thermodynamic limitation must …

Liquid-Amine Infused Surfaces for Carbon Capture
… wetting layers capture CO<sub>2</sub> via a reaction to form carbamate. The large interfacial areas per unit volume far exceed the values for commonly used amine scrubbing towers. In addition, the large thickness and the use of pure amines in SWIRL, provides an increase in capacity for …

Understanding and Improving Electrochemical CO2 Capture by Supercapacitive Swing Adsorption
… was an inherently kinetic effect and becomes a reversible process when the voltage was held for longer durations. This reversibility showed the system performance would be dependent on the charging rate and investigation revealed the charging rate that maximised the CO2 adsorption capacity for …
