Carbon

Knowledge of the evolution of soil properties in a constructed wetland is important for a correct design and performance assessment of the system over time. We evaluated the medium-term evolution of some chemical (pH, electrical conductivity [EC], organic carbon [OC], total nitrogen [TN], and total

In the context of gold extraction, leaching is the dissolution of the metal or even a mineral in a liquid phase. Thus, it is of a primary concern the dissolution of gold in an aqueous solution, operation which requires both a complexant and an oxidant to achieve acceptable leaching rates and yields.

The present investigation was undertaken to shed light on the failure of some 90/10 Cu-Ni condenser tubes in a MSF distiller. The tubes showed numerous tiny pits of unusual features. Particles of C were discovered inside the tubes and were suspected of initiating micro-galvanic cells leading to pitt
