Particle Image Velocimetry (PIV) is a non-invasive optical measurement technique where the velocity field of an entire region within the flow is measured simultaneously. It is a powerful quantitative flow field mapping technique that can provide the extraction of measurement data and the visualization of flow structures. A typical PIV setup includes a camera, a high-power pulsed […]
Hand sanitizers are a crucial element in the fight against disease. The active ingredient in hand sanitizer is alcohol, either ethyl or isopropyl alcohol. It has been shown that alcohol concentrations must be above 60% v/v to be effective. A simple, rapid, and non-destructive test of concentration can help avoid producing or using ineffective hand

Adhesion is important in all applications where two different materials are bonded together. This includes the application of coating such as paint or varnish, bonding with the help of adhesive, and printing. Wettability is required for good adhesion, and because of this contact angle, and surface free energy measurements are often used to evaluate the surface before

In pharmaceutical research and development, there is a vast number of surfaces of which behavior and properties need to be considered and tailored for optimal performance in the interaction with the surrounding environment. Examples of such surfaces are coatings of end-products, such as pharmaceutical tablets, whose properties significantly influence both the delivery and the release
