Mass Transfer and Drop Size Distributions in Reactive Nanoparticel-Stabilized Multiphase Systems, 2017
— Authors: Petzold, M., Röhl, S., Hohl, L., Stehl, D., Lehmann, M., von Klitzing, R. und Kraume, M. — Chemie Ingenieur Technik, 89 (10) (link) Mass transfer in stirred liquid-liquid systems with and without silica nanoparticles is investigated for the saponification of benzoyl chloride. The mass transfer area is positively
The formation of complex droplets in liquid three phase systems and their effect on dispersion and phase separation, 2017
— Authors: Hohl, L. und Kraume, M..— Chemical Engineering Research and Design: 89 (11), 1561–1573 (link) The phase behavior of microemulsion systems consisting of oil, water and non-ionic surfactants can lead to emulsions with unique properties: by adjusting temperature and composition a system with three liquid phases is obtained. These
Continuous two-phase biocatalysis using water-in-oil Pickering emulsions in a membrane reactor: Evaluation of different nanoparticles, 2017
— Authors: Heyse, A., Plikat, C., Ansorge-Schumacher, M. und Drews, A.— Catalysis Today: 12/2017 (link) Pickering emulsions are currently receiving increased attention as a promising alternative to dispersions or surfactant stabilized emulsions in two-phase biocatalysis. In order to design a continuous membrane reactor using water-in-oil Pickering emulsions for biocatalysis, knowledge
Chaotic Mixing Performance of Multiphase-fluid Intensified by Double Rigid-flexible Combination Impeller, 2017
Chongqing University, Chemical Engineering and Technology, 2017, PhD D. Thesis Database, China — Authors: Jun Zhu, Chanyuan Tao — As one of the core equipment of fluid mixing, stirred reactor is widely applied in many fields such as metallurgy, chemical industry, petroleum, which directly influences the efficiency of the whole
Application of Inline Imaging for Monitoring Crystallization Process in a Continuous Oscillatory Baffled Crystallizer (COBC), 2018
AIChE Journal (Link) — Authors: Kacker, R., Maaß, S., Emmerich, J. und Kramer, H. — In this study, an in-situ imaging system has been analysed to characterize the crystal size, the shape and the number of particles during a continuous crystallization process in a COBC. Two image analysis approaches were examined for particle
The impact of grinding intensity on particle properties and rheology of dark chocolate, 2018
LWT: 92, 564-568 (link) — Authors: Rohm, H., Böhme, B. und Skorka, J. — Comminution of the solid contents during chocolate manufacture is an important process that affects physical and sensory properties of the final product. In this study, size reduction was achieved either by multiple passages through a roller refiner, or
Real-time monitoring of the budding index in Saccharomyces cerevisiae batch cultivations with in situ microscopy, 2018
Microbial Cell Factories (link) — Authors: Marbà-Ardébol, M.-A., Emmerich, J., Muthig, M., Neubauer, P. und Junne, S. — Background The morphology of yeast cells changes during budding, depending on the growth rate and cultivation conditions. A photo-optical microscope was adapted and used to observe such morphological changes of individual cells directly
Oil Droplet Size Distributions in Deep-Sea Blowouts: Influence of Pressure and Dissolved Gases, 2018
Environmental Science Technology (link) — Authors: Malone, K., Pesch, S., Schlüter, M., und Krause, D. — To date, experimental investigations to determine the droplet size distribution (DSD) of subsea oil spills were mostly conducted at surface conditions, i.e. at atmospheric pressure, and with dead, i.e. purely liquid, oils. To investigate the influence
