A basic requirement of any coating is that it should form a uniform, defect-free surface. Surface and interfacial tensions play a key role in that.
To avoid potential adverse effects, it is relevant to study how nanoparticles interact with their surroundings. Here we present examples of how nanoparticle interaction with a variety of surfaces can be analyzed.
Contact angle hysteresis is often measured with so-called tilting cradle or plate method. The measurement can be done either manually or automatically.
Most commonly used methods to study reservoir wettability are Amott-Harvey, USBM, and sessile drop contact angle.
Dynamic contact angle measurements with the needle method has been automated for reliable and repeatable results.
Working in a surface science lab, you surround yourself with analysis equipment that you need to progress in your work. The benefits of running combination measurements could be three-fold.
Carbonate reservoirs are characterized as intermediate to oil- wet. Altering the wettability of the carbonates has been proposed as one of the main mechanisms for enhanced oil recovery.
Biosensing is a crucial part of human well-being as early detection of diseases requires highly sensitive and selective methods. New materials, such as graphene oxide, are evaluated for improved biosensor performance.
Different enhanced oil recovery methods are used to alter the wettability of the reservoir rock. To study the wettability alteration at the reservoir conditions, an instrument where the measurements can be done at high pressures and temperatures are needed.
