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.

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.

Advancing Lithium-Ion Battery Technology Through Rheology

Lithium-ion batteries represent the dominant rechargeable battery on the market today.  They can be found in many applications including consumer electronics, electric vehicles and industrial equipment. Due to the tremendous adoption of lithium-ion batteries in recent years, battery technology is the focus of a diverse set of research areas aiming to improve battery lifetime, performance and safety.   

How Sustainable Polymer Development is Supported by Dynamic Mechanical Analysis

Dynamic mechanical analysis (DMA) is a technique to measure the response of materials when they are subjected to dynamic or cyclic forces. Typically, dynamic mechanical analysis involves looking at the elastic and viscous response of the material when it is under a small oscillating load that probes the molecular structure’s response to the perturbation . Other variables, such as temperature, time and frequency may be changed as part of the testing to characterize how the material performs under different environmental conditions.

Optimization of Catalytic Reactions by High-Pressure TGA

Catalytic reactions are everywhere: from plastics and bread to over 90% of all chemicals worldwide, countless goods and materials are manufactured with the aid of catalysts.1 Catalysts are substances that speed up sluggish chemical reactions. Faster reactions are more technologically and economically competitive. Furthermore, optimized catalysts offer a huge potential to reduce energy and resource consumption and lower carbon dioxide emissions.
