• On-line particle analysis in wet processes
  

  Fully automated particle size measurement technology integrated with existing plant control platforms for ease of use has the potential to deliver numerous benefits. At plants where a switch to on-line analysis has been made it is frequently easier or possible to: more

• New since 5000 years
  

  Although the ancient Egyptians already used inks 5000 years ago, inks and their properties have been continuously improved and refined over thousands of years. Nevertheless, the basic principle of tinta acqua (colored water) remains the same. Today, in addition to inks based on dissolved dyes, there are many which contain pigments in solid form. Unlike dyes, pigments do not dissolve in the medium but are present in dispersed form, e.g. as suspensions. Pigment-based inks have an advantage over those containing dissolved dyes: after drying, they are light-stable and less sensitive towards water or other solvents. They also have higher color intensity. This is an important criterion for the 'permanent document' quality rating more

• Passivation of high‐surface‐energy sites of milled ibuprofen crystals via dry coating for reduced cohesion and improved flowability

  Abstract Ibuprofen micronization with dry coating is investigated to examine its influence on passivation/stabilization of high‐surface‐energy sites and reduced cohesion. A fluid energy mill was used to micronize ibuprofen particles down to 5–28 μm with or without simultaneous nanosilica coating more

• Detection of low level cryoglobulins by flow cytometry

  Abstract Several patients with cryoglobulin (CG) associated symptoms are seronegative for CG and other potentially causative biomarkers. We analyzed whether it is possible to detect cryoprecipitates by flow cytometry and whether the sensitivity of their demonstration can be increased as compared more

• Improved assessment of aggregate size in Taxus plant cell suspension cultures using laser diffraction

  In suspended culture, most relevant for biotechnological application, plant cells form aggregates. This phenomenon is of importance as it is related to productivity, leads to local heterogeneities, and might be a reason for the considerable shear sensitivity of these cultures. The valid measuremen more
