    How to deposit nanoparticles?

    There are several ways to deposit nanoparticles. Most methods are able to coat the surface, but for controlled monolayer deposition, more sophisticated methods are needed.

    Characterization of polyelectrolyte multilayer build-up and structure

    The versatility of polyelectrolyte multilayers, PEMs, is high, which makes them interesting for e.g. biomedical applications. The functionality is largely determined by the layer properties, which needs to be understood to be tailored. Here, we show how PEMs can be characterized with QCM-D.

    What is contact angle hysteresis?

    Contact angle hysteresis (CAH) is an important physical phenomenon. When you look through the window on a rainy day, you have probably noticed that some of the water droplets stick to the glass even though gravity is pulling them down. The phenomenon can be explained by contact angle hysteresis.

    How to characterize surfactant solutions?

    Surfactants are used in many industrial fields. Characterization of surfactants is thus important to optimize their performance and the products they are applied to. Surface and interfacial tension measurements offer versatile method to study the properties and behavior of the surfactant solution.
