  2. 1. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation

    Author : Mohsen Parchami; Mohammad J Taherzadeh; Sudip Rakshit; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brewer s spent grain; Hydrothermal pretreatment; Organosolv pretreatment; Edible filamentous fungi; Anaerobic digestion; Biorefinery; Resource Recovery; Resursåtervinning;

    Abstract : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. READ MORE

  4. 2. Network Programming Applied too Operation Planning of Hydrothermal Power Systems

    Author : Håkan Brännlund; Janis Bubenko; KTH; []

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; photocatalysis; zinc oxide; quantum dots; nanorods; quantum confinement; low-dimensional; cathodic electrodeposition; Raman spectroscopy; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Abstract : The increasing demand for clean energy and safe water resources has driven the development of efficient and sustainable technologies. Among these technologies, photocatalysis using semiconducting materials has emerged as a promising solution for both solar hydrogen generation and water purification. READ MORE

  6. 4. The Tjårrojåkka apatite-iron and Cu (-Au) deposits, northern Sweden : products of one ore forming event

    Author : Åsa Edfelt; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Tjårrojåkka area is located about 50 km WSW of Kiruna, northern Sweden, and hosts one of the best examples of spatially related apatite-iron (Kiruna type) and Cu (-Au) deposits in Sweden. The results from this project show that the two deposits are genetically related and indicate the presence of a younger, previously unknown, 1780 Ma generation of apatite- iron ores in northern Sweden.

  7. 5. Fluid migration and brittle tectonothermal evolution in the central Fennoscandian Shield - recorded by fracture minerals and wall rock alteration

    Author : Björn Sandström; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Forsmark area in central Sweden has been investigated as a potential geological host for a final repository of spent nuclear fuel by the Swedish Nuclear Fuel and Waste Management Company (SKB). High quality drill core material from the upper 1 km of the central Fennoscandian Shield has been obtained during the site investigations and has provided a unique opportunity for detailed fracture mineralogical investigations.
