The mass extracted by QCM-D and ellipsometry are often not the same. So, what is the difference between these masses, and why are they not equal?

Blood-repellent surfaces are needed in medical devices that come in contact with blood. The traditional approach has been the use of antithrombotic surface treatments However, these coatings are prone to eventually wear-off. Superhydrophobic surfaces have been proposed as an alternative solution.
A term surfactant comes from the word surface active agent. At the interface, they align themselves so that the hydrophobic part is in the air and hydrophilic part is in water. This will cause the decrease in surface or interfacial tensions.
Nanoparticle thin film-based sensors offer several advantages over traditional sensor types, especially in electrochemical sensing. The main challenge has been the fabrication of the nanoparticle sensing layer. Two main methods have been used; layer-by-layer (LbL) and Langmuir-Blodgett (LB).
The official World Cup ball 2018 is called Telstar 18, inspired by the original Telstar that was made for 1970 games. It resembles the one used in 1970 by the appearance but that's where the similarities end. Have you ever thought how much science is put behind to develop the perfect soccer ball?
Nanoparticle thin films are finding applications in areas where functional coatings are needed. How to produce these nanoparticle thin film needs to be considered. Dip coating offers one of the simplest methods to coat the substrate with nanoparticles.
