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.
Contact angles are routinely measured as they offer simple, yet extremely sensitive measurement method for surface characterization. Although, the static contact angle is an excellent tool, more in-depth understanding of the surface properties require dynamic contact angle measurements.
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.
