Membrane‐Freeze Concentration Hybrid for Temperature‐Sensitive Biomolecules. Investigation, Application, and Techno‐Economic Benefits Timo van Beek, Michael Budde, Jan van Esch Abstract In order to close the technology gap between membrane technologies and spray/freeze‐drying ideally with a technology that avoids thermal stress to sensitive enzyme solutions, the limits of freeze concentration for this application have been investigated.… Continue reading Membrane‐Freeze Concentration Hybrid for Temperature‐Sensitive Biomolecules. Investigation, Application, and Techno‐Economic Benefits

How different nanoparticles affect the rheological properties of aqueous Wyoming sodium bentonite suspensions Abstract Clay suspensions present complex microstructures in different environments and deep understanding of such microstructures is crucial to control their flow properties. Their rheological profile is closely linked with the structural association (3-D network) of bentonite particles. Nanomaterials are considered very good… Continue reading How different nanoparticles affect the rheological properties of aqueous Wyoming sodium bentonite suspensions

Effect of porous structure and spreading pressure on the storage stability of red onion microcapsules produced by spray freezing into liquid cryogenic and spray drying L.A. Pascual-Pineda, M.P. Rascón, M.X. Quintanilla-Carvajal, M. Castillo-Morales, U.R. Marín, E. Flores-Andrade Abstract Red onion microcapsules were produced by spray freezing into liquid cryogenic (SFLC) and spray drying (SD) and… Continue reading Effect of porous structure and spreading pressure on the storage stability of red onion microcapsules produced by spray freezing into liquid cryogenic and spray drying

Freeze Granulation for the Processing of Silicon Nitride Ceramics Ola Lyckfeldt, Kent Rundgren, M. Sjöstedt Abstract Freeze granulation (LS-2, PowderPro HB, Sweden) has been demonstrated as a favourable alternative to conventional granulation methods (spray drying, sieve granulation etc) in the production of granules for the pressing of high-performance ceramic powders. Freeze granulation/freeze drying prevents the… Continue reading Freeze Granulation for the Processing of Silicon Nitride Ceramics

Selective Oxidation of HMF via Catalytic and Photocatalytic Processes Using Metal-Supported Catalysts Lolli A, Maslova V, Bonincontro D, Basile F, Ortelli S, Albonetti S Abstract In this study, 5-hydroxymethylfurfural (HMF) oxidation was carried out via both the catalytic and the photocatalytic approach. Special attention was devoted to the preparation of the TiO₂-based catalysts, since this… Continue reading Selective Oxidation of HMF via Catalytic and Photocatalytic Processes Using Metal-Supported Catalysts

Modern frontiers and applications of spray-freeze-drying in design of food and biological supplements Sayantani Dutta, J. A. Moses, C. Anandharamakrishnan Abstract Spray‐freeze‐drying (SFD) is a unique tandem technique combining spray drying (SD) and freeze drying (FD), and exploiting the advantages of both. SFD is particularly suitable for volatiles, biologicals, and food supplements that are sensitive… Continue reading Modern frontiers and applications of spray-freeze-drying in design of food and biological supplements
