Insects that can walk on water? Fabrics that let dirt and water simply bead off? Interfacial tension explains many everyday phenomena. It also matters greatly in chemistry and engineering. Where …

In laboratory environments, substances often need to be free of moisture, samples must be kept dry, or stored under constant humidity conditions. Desiccants for gases, liquids, or solids – as …

Since the second phase of the Industrial Revolution in the 1870s, a modern world without rubber has been almost inconceivable. The material is encountered wherever something must be sealed to …

Polystyrene, PS, Styrofoam or styrene plastic – this material is as versatile as its many names. The thermoplastic made up around 5.2%[1] of the world’s plastic production in 2023. It …

In terms of cost efficiency, calendering technology remains indispensable not only in the production of fabrics, textiles, and paper and in achieving specific surface finishes. It also demonstrates clear advantages …

Many industries rely on filtration as a key separation technique. When particles and substances are removed from liquids and gases using a membrane, membrane filtration comes into its own. Depending …

In the past, per- and polyfluoroalkyl substances were grouped under various terms such as per- and polyfluorinated chemicals, perfluorinated organic compounds, or highly fluorinated substances. In polyfluorinated alkyl substances, hydrogen …

Lubrication technology is the invisible force that keeps machines running. It minimises friction and wear, improving the service life and efficiency of components. This article introduces lubrication technology, explains how …

Sum parameters play an important role in the analysis of water samples from drinking water, surface water, groundwater, and wastewater, as well as sewage sludge. When determining sum parameters, a …

Flow sensors are ubiquitous in process chemistry operations. But what operating principles are these volumetric flow measurement devices based on, what designs are available, and where are they used? This …
