  1. 16. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Author : Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Wood board industry; chamber methods; dynamic microchamber DMC ; bio-based adhesives; lignosulfonates; supercritical water hydrolyzed lignin; crosslinkers; fibreboards; particleboards; Forestry and Wood Technology; Skog och träteknik;

    Abstract : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

  2. 17. Organocatalytic Domino Reactions

    Author : Henrik Sundén; Armando Córdova; Pavel Kočovský; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; organocatalytic; domino; iminium-enamine; enamine-iminium; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : Organocatalyzed reactions involving activation strategies of ketones and aldehydes are important processes in organic chemistry. These activation strategies serve as a versatile platform for the construction of several domino reactions. READ MORE

  3. 18. Simulation of Chemical Reactors

    Author : Tommy Hertzberg; Institutionen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid flow; chemical reactors; formox; fractional step; catalytic combustion; Spectral methods; self-adjoint operator; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : This thesis consists basically of two parts. They are, however, interrelated by the fact that both parts concerns modelling of catalytic reaction systems and also by the fact that in both parts, spectral methods are used for simulation. The first part describes the numerical treatment of the dispersion model. READ MORE

  4. 19. Chemical reactions in aluminium electrolytic capacitors

    Author : Ildiko Szaraz; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Aluminium electrolytic capacitors are used in a wide variety of different applications. The aluminium electrolytic capacitor consists of two aluminium foils wound together and separated by special paper, which is impregnated with an electrolyte. READ MORE

  5. 20. Palladium(II)-Catalyzed Heck Reactions : Domino Reactions, Decarboxylations, Mechanistic Studies & Continuous Flow Applications

    Author : Ashkan Fardost; Mats Larhed; Patrick Guiry; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; palladium II ; dft; reaction mechanisms; esi-ms; heck; decarboxylation; microwave; continuous flow;

    Abstract : This thesis describes research efforts dedicated to the development of palladium(II)-catalyzed oxidative Heck and Heck/Suzuki domino reactions, and the applications of a new microwave heating technology, purpose-built for continuous flow in organic synthesis.Paper I describes the development of a ligand-modulated approach for attaching aryl groups to a chelating vinyl ether.
