  2. 16. Influence of Internal Diffusional Limitations on the Performance of an Immobilized Enzyme in Organic Medium

    Author : Raúl J Barros; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biotechnology; internal diffusional; acetonitrile medium; Immobilized a-chymotrypsin; kinetically controlled peptide synthesis; Bioteknik;

    Abstract : The influence of mass-transfer limitations on the performance of immobilized a-chymotrypsin operating in acetonitrile medium has been investigated. The enzyme was immobilized by deposition on various porous carrier materials such as celite, polyamides of different particle sizes, controlled-pore glasses, polypropylene or polyacrylamides.

  4. 17. Aerosol-water interaction at sub and super-saturated regimes : From small scale molecular mechanisms to large scale atmospheric models

    Author : Narges Rastak; Ilona Riipinen; Maria Kanakidou; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; miljövetenskap; Environmental Sciences;

    Abstract : The term “atmospheric aerosol” refers to solid or liquid particles suspended in the atmosphere. Atmospheric aerosols influence the Earth’s energy budget directly by scattering and absorbing radiation (known as the direct aerosol effect) and indirectly by acting as cloud condensation nuclei (CCN) and ice nucleating particles and thereby modifying cloud properties (known as the indirect aerosol effect).
