  4. 2. Recovery of Scandium using Antisolvent Crystallization in the Valorization of Scandium-containing Waste Streams

    Author : Edward Peters; Kerstin Forsberg; Michael Svärd; Jens-Petter Andreassen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antisolvent crystallization; ammonium scandium hexafluoride; ammonium metal fluorides; phase equilibria; solubility; supersaturation; seeding; agitation mechanism; crystal size distribution; morphology; Chemical Engineering; Kemiteknik;

    Abstract : Scandium is widely dispersed in the earth’s crust and is rarely concentrated in ores, and a viable option to guarantee a secure supply of scandium is to recover the metal from waste streams of other mining and metallurgical facilities. The valorization of such streams to recover metals of value is a prerequisite to alleviate the global shortages of scandium and other rare earth elements. READ MORE

  5. 3. Cryogels Based on Crosslinked Cells as Green Biocatalysts for Biotechnology

    Author : Oksana Zaushitsyna; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cells; Crosslinkers; PVA PEI; Immobilization; Biocatalysts; Biobased chemicals; Biotransformation; stress tolerance;

    Abstract : Abstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide bio-based chemicals. READ MORE
