  3. 2. Catalyst Design for the Valorisation of Biomass-derived Furans into Aromatics

    Författare :Guido J.L. de Reijer; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; aromatics; 2; 5-dimethylfuran; gallium; biomass; furans; production of aromatics; zeolites; biomass conversion; catalysis;

    Sammanfattning : Anno 2023, mankind must strive towards a more sustainable chemical industry; one that does not solely rely on fossil fuels but also utilises renewable feedstocks such as biomass. Biomass can be catalytically converted into commodity chemicals such as aromatics, through intermediates like furans. LÄS MER

    Sammanfattning : New measurements of the elements Ba, Fe, Ga, In and Ru are reported. The analysis of barium contains new wavelengths, improved energy level values and new values of the ionization limit in both Ba I and Ba II. Oscillator strengths and radiative lifetimes in Fe II, as a part of the FERRUM project, are reported. LÄS MER

  5. 4. Antivirulent and antibiofilm salicylidene acylhydrazide complexes in solution and at interfaces

    Författare :Shoghik Hakobyan; Madeleine Ramstedt; Jean-Francois Boily; Mikael Elofsson; Marcus Textor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Antivirulent; Antibiofilm; Hydrazones; Gallium; Pseudomonas aeruginosa; Type three secretion system; Equilibrium constant; Chemical equilibrium modelling; Spectrophotometric titration; UV-Vis;

    Sammanfattning : The growing bacterial resistance against antibiotics creates a limitation for using traditional antibiotics and requests development of new approaches for treatment of bacterial infections. Among the bacterial infections that are most difficult to treat, biofilm-associated infections are one of the most hazardous. LÄS MER
