Rheology of Paints and Coatings

From shiny cars to streak-free walls, we demand a lot from our coatings and paints. A high-quality paint not only needs dazzling color, but also must offer the right material properties for a smooth application and drying process. Consistency is crucial: too thin and the paint will run and drip; too thick and it will clump and not dry evenly. Spray paints and coatings also need to be applied smoothly without clogging the spray device.

How To Optimize Lyophilization with Thermal Analysis

Lyophilization, also called freeze-drying, is the process of removing water from a sample, often for preservation. Lyophilization involves the sublimation of a sample’s water content, usually through a rapid freezing process. Freezing materials quickly helps avoid the destruction of the cell walls in the sample from the formation of large ice crystals.

Rheology of Hydrogels

Hydrogels are three-dimensional porous strctures that can absorb large amounts of water. They can be made up of polymers, protein, peptides, colloids, surfactants, or lipids.1 Hydrogels’ ability to uptake large amounts of water is useful for many biological applications, including drug delivery and tissue engineering. Since a hydrogels’ properties change as it absorbs water, scientists must accurately characterize its behavior at different saturation amounts and in varying conditions.

Material Analysis for Bioplastics Quality Assurance and Degradation

What are bioplastics? How can plastic manufacturers use them to improve the environmental impact of their products? With so many emerging green technologies, producers and consumers need to differentiate between greenwashing1 and genuine advancements. Furthermore, if a new development is deemed environmentally beneficial, all stages of the plastics supply chain, especially converters, must then learn how to incorporate the new technology without undermining their process or products.
