  1. 1. Photoredox catalysis enabled C–O bond activation: Access to unnatural amino acids

    University essay from KTH/Kemi

    Author : Josefin Lantz; [2021]
    Keywords : photoredox catalysis; unnatural amino acids; alkyl oxalate; visible light; radicals; fotoredoxkatalys; icke-naturliga aminosyror; alkyloxalat; synligt ljus; radikaler;

    Abstract : Fotoredoxkatalys tillhandahåller möjligheter att utveckla nya hållbara kemiska reaktionsvägar. När fotokatalysatorn bestrålas med synligt ljus möjliggörs elektronöverföring till eller från substratet som i sin tur medför alstring av reaktiva fria radikaler. READ MORE

  3. 2. Evaluating the suitability of carbon source from fermentation of primary filter sludge for biological nutrient removal

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Sanna Sahlin; [2021]
    Keywords : Wastewater treatment; batch activity tests; NUR tests; anaerobic P release tests; EBPR; denitrification; removal rates; internal carbon source; fermentate; water and environmental engineering; Technology and Engineering;

    Abstract : Traditional biological nutrient removal (BNR) processes in wastewater treatment require access to easily biodegradable carbon in order to achieve sufficient removal. However, a lot of the carbon in the influent wastewater is not directly available for BNR bacteria but need to undergo hydrolysis first. READ MORE

  4. 3. Aroma components of long ripened cheese and their origin, variation and contribution to flavour : with focus on propionic acid

    University essay from SLU/Department of Molecular Sciences

    Author : Sandra Carlsson; [2021]
    Keywords : cheese ripening; aroma components; volatile compounds; metabolism of lactose; lactate and citrate; ; proteolysis; lipolysis; propionic acid bacteria; sensory evaluation;

    Abstract : Flavour compounds in cheese are formed by metabolism of residual lactose, lactate and citrate, proteolysis and lipolysis through the activity of e.g., starter bacteria. Generally identified aroma components in cheese are fatty acids, esters, alcohols, ketones, lactones, aldehydes, and sulphur compounds. READ MORE

  5. 4. Conversion of CO2 to higher alcohols

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Joshua Higby; [2020]
    Keywords : CO2 hydrogenation; higher alcohols; modelling; process intensification;

    Abstract : I rapporten framgår det en termodynamisk analys för reverse water gas shift med att sammanmata etanol för att undvika det långsammaste steget i reaktionen för att producera högre alkoholer. Ifrån ett termodynamiskt perspektiv, verkar det möjligt att utgå ifrån reverse water gas shift för att producera högre alkoholer vid 100 bar med en temperatur på 300C . READ MORE

  6. 5. Trifluoromethoxylation of Allylic Alcohols via 1,2-Aryl Migration Promoted by Visible Light-Mediated Photoredox Catalysis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Shuai Qiu; [2020]
    Keywords : Photoredox Catalysis; Fluorination; Trifluoromethoxylation; tvisible light; allylic alcohols; fotoredoxkatalys; trifluorometoxylering; synligt ljus; allyliska alkoholer;

    Abstract : Visible light photoredox catalysis has proven to be a powerful tool for promoting transformations in organic synthesis. Hence this project was carried out to develop tools for predicting reactivity patterns of visible light- promoted redox reactions. Fluorination is of immense importance in organic chemistry, and so is trifluoromethoxylation. READ MORE
