21. Voltage Sags: Single event characterisation, system performance and source location
Sammanfattning : This thesis deals with one of the most important disturbances that affect the quality of the electrical supply. Voltage sags cause industrial processes malfunction, producing an enormous economical impact. A voltage sag is defined as a short duration reduction of the rms voltage. LÄS MER
22. Operando Characterisation of Lithium–Sulfur Batteries
Sammanfattning : Lithium–sulfur (Li–S) batteries have been under the spotlight of research on electrochemical energy storage systems, primarily owing to their high theoretical specific energy (2552 Wh kg-1). So far, Li–S cells on the market have presented a specific energy of 400 Wh kg-1, which is superior to many commercial alternatives, but far below the theoretical value. LÄS MER

25. Enzyme Hydrolysis of Cellulose Derivatives. Active Site Studies and Polymer Characterisation
Sammanfattning : Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. LÄS MER
