  1. 1. Water treatment using cryogel-based adsorbents - Targeting environmental pollutants at low concentrations

    Author : Linda Önnby; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adsorption; cryogels; nanoparticles; arsenic; cadmium; water treatment; composites;

    Abstract : The lack of safe, clean water is strongly linked to poverty, underdevelopment and poor health. Water is needed not only to sustain life, but to produce food and in industrial processes. Anthropogenic pollution and natural events can jeopardize access to safe water. READ MORE

  2. 2. Anaerobic digestion of crop and waste biomass: Impact of feedstock characteristics on process performance

    Author : Nges Ivo Achu; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Biofertilizer; Renewable energy; Sustainable operation;

    Abstract : Anaerobic digestion provides an array of positive environmental benefits such as reducing greenhouse gas emissions, replacing mineral fertilizers, producing renewable energy and treating waste. However, pitfalls in anaerobic digestion such as poor methane yields, process instability, process failure and regional shortages of feedstock have limited the full exploitation of the anaerobic digestion process.

  3. 3. Particulate Formation in Gasoline Direct Injection Engines

    Author : Sreelekha Etikyala; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Volatileorganic compounds; Particulate Number; Alternate fuels; Gasoline Direct Injection; PM;

    Abstract : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.

  4. 4. Virus inactivation : evaluation of processes used in biowaste management

    Author : Eva Emmoth; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Animal by-products (ABP) Category 3 includes hatchery waste, and also slaughterhouse waste and manure, aimed for use in biogas production. In order to be used as fertilisers, they must be sanitised to reduce pathogenic microorganisms. The initial European regulations regarding processing standards for ABP intended for use in e.g. READ MORE

  5. 5. N-Heterocyclic Carbene Catalysis in Organic Synthesis - A Green Chemistry Approach

    Author : Linda Ta; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; aerobic oxidation; ionic liquid; sustainability; NHC catalysis; oxidative NHC catalysis; green chemistry; OTHO; Organocatalysis;

    Abstract : The twelve principles of green chemistry were created as a response to the multiple environmental issues caused by the release of waste from the chemical industry. The principles acts as a guide in the development of sustainable chemical processes for the syntheses of important molecules needed to sustain our living standards. READ MORE
