In fact, thanks to its organic functionalities (i.e., hydroxyl, carboxyl, epoxy groups), it can react easily to form stable dispersions. An example is represented by the functionalization of graphene oxide with phytic acid, as shown in Figure 4a,b. This latter is a naturally abundant ...
Petroleum is defined as a gaseous, liquid, and semisolid naturally occurring substance that consists chiefly of hydrocarbons (chemical compounds of carbon and hydrogen).Petroleum is therefore a term that includes both oil and natural gas.Petroleum is nearly always found in marine sedimentary rocks.In...
