    Six measurement techniques for nanoparticle size characterization

    Nanoparticle size is one of the key parameters that are relevant to characterize in nanoparticle suspensions. Here we list six different methods that you can use to characterize the nanoparticle size.

    Why is wettability important in enhanced oil recovery?

    In enhanced oil recovery wettability plays an important role as that determines the interactions between the solid (rock) and the liquids in the reservoirs (crude oil, brine). Wettability has been recognized as one of the key parameters controlling the remaining oil-in-place.

    What is wettability?

    Wettability is the preference of a liquid to be in contact with a solid surrounded by another fluid (liquid or gas). Depending on the application, wettability can be wanted or not.

    What is graphene oxide?

    Graphene oxide (GO) is the oxidized form of graphene. Graphene oxide is easy to process since it is dispersible in water and other solvents. Due to the oxygen in its lattice graphene oxide is not conductive, but it can be reduced to graphene by chemical methods.

    What does self-cleaning mean?

    A self-cleaning surface is any surface with the ability to readily remove any dirt or bacteria on it. Self-cleaning surfaces can be divided into three different categories; superhydrophilic, photocatalytic and superhydrophobic.

    Why is contact angle important?

    In industry, wettability is important for example when manufacturing electronics or when planning how to extract oil from the oil reservoir. In all these applications, knowing the contact angle value gives a strong indication on the performance of the product or a successfulness of the process.

    How to characterize nanoparticle suspensions

    Nanoparticle suspensions are complex systems and their characterization includes several parameters such as size, concentration in solution, shape, surface charge and chemical composition. Here we provide a list of methods that could be used to characterize nanoparticle suspensions.

    What is surface tension?

    The net force, which effectively aims to keep the liquid together, is called surface tension.

    What is contact angle?

    Contact angle is easy to understand visually. It is the angle a droplet forms in contact with a solid surface. Thermodynamically, it is a balance between different forces acting on a three-phase contact point where solid, liquid and air meet.
