  • For the quality and safety of filter media
  • the retention capacity for particulate components in liquids is often a critical factor. Particle size
  • size distribution and particle number are important characteris-tics
  • whose determination requires valid measuring methods. Number-based quantifying becomes more difficult the smaller the particles to be examined are and creates great challenges for the measurement technology
  • especially for particles of nano- and sub-micrometer range. In this paper we describe the measuring technique of an advanced photometer measuring simultaneously forward and sideward light scattering of single particles (SPLS-Technology). Light intensities allow to determine size distribution and particle concentration of nano- and microparticles in suspensions and emulsions with unparalleled resolution and a dynamic range from below 50 nm to 8 µm. In this paper we report about the application of these measuring technique for filter media and membrane testing (cut-of).

We used a versatile strategy to produce a stable Pickering emulsion by depletion interaction between an emulsion droplet and a particle using solvent-soluble polymers as a depletant. This interaction facilitates the adsorption of particles onto the droplet interface and stabilizes the emulsions. The coating formulation is based on water-in-toluene emulsions stabilized using commercial hydrophobic silica

  • Capsaicin (CAP) is a hydrophobic substance with various physiological effects in chili peppers that is responsible for their perceived heat. Nonetheless
  • its application as a nutraceutical is hugely hindered by its low bioaccessibility and mucosal irritation. In this study
  • capsaicin was entrapped in the water phase of water-in-oil (W/O) high internal phase emulsions (HIPEs) using a pH-driven method. Initially
  • the capsaicin was mixed with sodium alginate (SA) to form a water-dispersible form of the capsaicin and then used to form CAP-loaded W/O HIPEs. The influence of capsaicin concentration on the properties of W/O HIPEs was then investigated.
