Hydraulic fracturing fluids commonly consist of water, ‘proppants’ and chemical additives that open, enlarge and maintain fractures within the rock formation. The proppants – sand, ceramic pellets or other small incompressible particles – hold the newly created fracture open. The fracture widths are generally equal to a few diameters of the grains used in the […]

Research on the application of titanium dioxide as a photocatalyst has been carried out in many fields since it was discovered that this substance causes water splitting when exposed to ultraviolet light. For example, a titanium dioxide photocatalyst has been put into practical use for the decomposition of poisonous gas, etc. However, due to the […]

The discovery, which has previously only be theoretically-predicted by scientists, helps explain the interactions between single oxygen molecules and titanium dioxide, giving the research teams a better idea of how the compound functions. The scientists also say that it could point to further enhancement of the compound, as well as different functions, including the possibility […]

Imagine a city that could devour the very pollution that it creates. Such was the scenario envisioned by scientists in the Netherlands, who have found that using specially treated pavement on city streets can cut air pollution nearly in half. The researchers from Eindhoven University of Technology installed concrete paving which included titanium dioxide ­– […]

Oil and gas companies continue to explore new and improved methods of minimizing precipitation of iron compounds during acid treatments of wells. Stannous chloride solution has been gaining significant popularity as an iron reducing agent (IRA). Strong reducing agents easily lose (or donate) electrons. An atom with a relatively large atomic radius tends to be […]
