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.
The quartz crystal microbalance, QCM, has been around since the 60’ where it has been used for monitoring of thin-film deposition and characterization of thin films. So how does this technology work?
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.
When, Nouryon (former AkzoNobel speciality chemicals), launched a new surfactant with a good dermatological profile, they wanted to prove superior performance vs competitive benchmarks. As the current test methods were not sensitive enough, they turned to an analysis using QSense cleaning profile.
Contact lens should support a continuous tear film for optimum visual clarity. It should also resist the sorption of tear components as deposition can lead to decreased visual clarity and discomfort. Wettability of the surface affects both the tear film as well as biocompatibility of the lens.
Model membranes are used in various fields of research. Read about how these lipid membranes can be characterized using QSense QCM-D technology.
You might find it confusing when seeing all the different methods for surface free energy calculations. As surface free energy can give you more information on your surface compared to the contact angle measurements alone, it is time well spent to study the different theories more in detailed.
