The Mzymta River (Black Sea coast, Russia) erodes different types of rocks. Among them, mudstones, siltstones and shales are predominating, and carbonate and clay-carbonate rocks are present in smaller quantities, and occasionally eruptive rocks are ...

Diagenesis is defined as the process involving physical and chemical changes in sediment after deposition that converts it to consolidated rock. Carbonate rocks are mainly composed of carbonate minerals only and have a polygenic origin, and thus are different considerably from clastic and pyroclastic rocks.

Methods for synthesizing diethyl carbonate from ethanol and supercritical carbon dioxide by one-pot or two-step reactions in the presence of potassium carbonate [PDF]
Carbon dioxide sequestration was studied by synthesizing diethyl carbonate (DEC) from ethanol and CO2 under supercritical conditions in the presence of potassium carbonate as a base. The co-reagent was ethyl iodide or a concentrated strong acid.

Sustainable Plant‐Based Water Repellent Coatings Using Hydrophobic Pine and Palm Pollen
A novel formulation strategy for creating superhydrophobic coatings using plant‐derived waxes and chemically treated pine and palm pollen. By employing acid modification, the hydrophobicity of the pollen surface is enhanced, resulting in water contact angles exceeding 150°.

Rapid determination of organic carbon in carbonate rocks.
A rapid method for determination of organic carbon in carbonate rocks has been developed to replace the normal procedure in which carbonate samples are pretreated with hydrochloric acid to decompose carbonate minerals. The method involves dry combustion of organic material in an oxygen stream and subsequent measuring of carbon dioxide (CO2) generated ...
