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.
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.
