courtesy of Particle Measuring Systems

Maintaining a contamination-free environment is a prerequisite for high-tech manufacturing and scientific research. Cleanrooms are central to this endeavour. Although a cleanroom is a critical part of maintaining a working environment, they cannot guarantee required cleanliness standards without robust monitoring systems such as particle counters and air quality monitors. A cleanroom particle counter directly contributes to air quality by measuring the concentration of airborne particles in the environment, which is essential for quality assurance (QA) and compliance. Here is a guide on how to choose the right particle counter for your cleanroom

Understanding the phase separation behaviour of microemulsions for enhanced oil recovery processes

winsorcourtesy of DataPhysicis

Microemulsion mixtures are commonly used for enhanced oil recovery (EOR) processes due to their high crude oil extraction efficiency. Generally, such mixtures consist of a thermodynamically stable dispersion of crude oil, surfactant, and water or brine. The phase behaviour of the mixture changes from Winsor I to Winsor II by the way of Winsor III when adjusting temperature, salinity, and pressure. The Winsor III state is the most desirable during the EOR process. The dispersion stability analysis system MultiScan MS 20 from DataPhysics Instruments (Fig. 2) is a compact and versatile measuring device for the optical stability and aging analysis of a variety of multi-phase dispersions. The phase behaviour of a crude oil, surfactant, and water mixture will be presented in this application note

Drying and Dehydration

courtesy of Surface Measurment Systems

Matter under ambient conditions interacts with moisture and volatiles continuously. Exposure to heat and a high airflow over material will induce some form of drying. A material’s ability to resist rapid transitions between wet/hydrated states can be a good measure of stability.

Removal of volatiles from the surface of a solid can have a significant effect on the surface area by collapsing fragile crystals, altering surface energy, and changing the hydrated state of a solid. The degree of wetting and interaction with moisture can significantly change a material’s function and performance, therefore, monitoring its wettability/dry-ability is ever more necessary.

Measuring the surface potential and isoelectric point of polyester fibres with a zeta potential analyzer

courtesy of DataPhysics

Fibres
Polyester fibres are synthetic fibres manufactured from polyethylene terephthalate. Polyester fibres are widely used in the textile industry. However, unmodified polyester fibres have deficiencies, e.g., a low water uptake, a hydrophobic character, and few reactive groups. This means they display a low affinity for dyes. Many techniques for improving the reactivity and hydrophilic character of polyester fibres exist in an industrial context. Generally, modifying fibres can enhance the interactions between the cations or anions of the dye and the functional groups on the fibre surface, and thus, the dyeability and water sorption of such fibres[1].
