  1. 1. Coverage increase in a plant-based BB cream formulation with natural pigments

    University essay from KTH/Kemi

    Author : Leelou Zoé Billot; [2024]
    Keywords : BB cream; Coffee; Coverage; Formulation; KAFFAGE®; BB cream; kaffe; täckning; formulering; KAFFAGE®;

    Abstract : Kaffe Bueno, ett bioteknologiskt start-up-företag dedikerat till framsteg inom naturliga och gröna produkter, fokuserar på att utnyttja den outnyttjade potentialen hos kaffebiprodukter genom grön kemi och bioteknik. Då endast 1% av kaffet används för bryggning, extraherar företaget lösliga och olösliga produkter genom en uppdelning mellan ett oljeutvinning och ett efterföljande vattenuttag, vilket bidrar till att sänka CO2-utsläppen per värde och en cirkulär ekonomi.

  3. 2. Protein digestibility of biorefined juice from fresh and ensiled ley crops in growing pigs

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Jhon William Perez Davila; [2023]
    Keywords : protein digestibility; amino acids; ley crops; silage; biorefinery; press juice; growing pigs;

    Abstract : The study aimed to evaluate the protein and amino acid digestibility of press juice from biorefined ley crops in the form of fresh (FPJ) and silage (SPJ) when included as an ingredient in liquid diets for pigs. The juice was extruded from ley crops mixture (grass-clover). READ MORE

  4. 3. Light-activated gas sensing with copper oxide micro- and nanostructures

    University essay from KTH/Fysik

    Keywords : Gas sensors; Gas sensing; Light-activation; Copper oxide; Cuprous Oxide; Nanomaterials;

    Abstract : Metal oxide semiconductor (MOS) gas sensors have proven to be useful in many applications, ranging from detection of hazardous gases to monitoring of air quality. The demand for power efficient and high performance gas sensors has seen an increase in situations facing contemporary society. READ MORE

  5. 4. Photocatalytic activity of titanium dioxide thin films deposited with high power impulse magnetron sputtering

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Victor Eriksson; [2021]
    Keywords : Photocatalysis; Titanium dioxide; Thin film; HiPIMS; Sputtering; Stearic acid;

    Abstract : High power impulse magnetron sputtering has shown a lot of promise as a way of depositing photocatalytic thin films of titanium dioxide at low temperatures, however, the films deposited are often amorphous and display uncertain photocatalytic abilities. This thesis explores the deposition and characterization of photocatalytic thin films deposited with high power impulse magnetron sputtering. READ MORE

  6. 5. Photocatalytic Degradation of Organic Substances in Salt Water

    University essay from KTH/Kemiteknik

    Author : Celice Carlsson; Love Wiklund; Emilie Svensson; Benjamin Fégeant; [2021]
    Keywords : Photocatalytic degradation; titanium dioxide; reactive halogen species; Tris hydroxymethyl aminomethane; methanol; competition kinetics; Fotokatalytisk nedbrytning; titandioxid; reaktiva halogen molekyler; Tris hydroxymetyl aminometan; metanol; konkurrenskinetik;

    Abstract : The purpose of this research was to investigate the kinetics and mechanisms of the photocatalytic degradation of organic substances in the presence of anions (bromide and chloride), using titanium dioxide as a photocatalyst. Tris(hydroxymethyl)aminomethane (Tris) and methanol were the organic substances used as probes. READ MORE
