Rational Design of Broad‐Spectrum Anti‐Enteroviral Molecular Glues Targeting Enteroviral RNAi Suppressors

open access: yesAdvanced Science, EarlyView.
By leveraging this homodimerization mechanism, molecular glues were rationally designed to induce dysfunctional 3A dimerization, thereby restoring antiviral RNAi. The optimal molecular glue, VTP‐32, demonstrated potent and pan‐enterovirus (groups A, B, D) antiviral effects.

Boil-off gas handling from liquefied hydrogen storage

open access: yes, 2020
The main objective of the thesis was to develop concepts for hydrogen boil-off gas reliquefaction. Three different processes were simulated, analyzed, and compared: helium Brayton refrigeration cycle with two helium turbine expanders, hydrogen Claude refrigeration cycle with two hydrogen expanders, and Brayton refrigeration cycle with two expanders for

Boil-off gas handling for LNG-carriers with a low-swirl burner

open access: yes, 2018
Wärtsilä is looking into a new technology for boil-off gas handling. The technology chosen for further research is a low-swirl burner. This burner has shown promising NOx emission results which is a problem inside the shipping industry. The system is a combined high/low-swirl burner that could handle both premixed- and none-premixed mixture.
