    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; catanionic surfactant; SANS; NMR; gel; sodium alkylsulfate; Protein-surfactant interactions; lysozyme; LH2; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : Aggregation in protein-surfactant systems have been studied with the ambition of reaching a deeper understanding of the balance of the interaction forces involved. A pure system with maximized electrostatic interactions has been used. LÄS MER

  4. 13. Oxygen formation in the chlorate process and preparation and deactivation of ozone selective anodes

    Författare :Staffan Sandin; Ann M. Cornell; Paul Christensen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATO; EOP; ozone; electrode preparation; elec- trode deactivation; hypochlorite; chlorate; oxygen; chromium VI ; sodium dichromate; electrocatalysis; catalysis; Chemical Engineering; Kemiteknik;

    Sammanfattning : This thesis presents experimental studies concerning two differ-ent electrolytic processes. One part deals with the electrochemicalformation of ozone and focuses on the preparation and deactiva-tion of a highly ozone-selective metal oxide anode (NATO - nickeland antimony doped tin oxide).

  5. 14. Thermodynamic modelling of black liquor-related solutions. Pitzer method for estimating activities, solubilities and boiling point rise

    Författare :Marta Anna Bialik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; activity coefficient; black liquor; boiling point rise elevation ; osmotic coefficient; solubility; Pitzer method; sodium sulphate dicarbonate; burkeite;

    Sammanfattning : Black liquor is considered as being one of the most important process streams as far as the design and optimization of kraft pulp mills are concerned. Many methods have been developed in order to describe and, possibly, predict its physico-chemical properties. Most of them are, however, empirical methods that are difficult to generalize. LÄS MER

  7. 15. Toward Safer Energy Storage Solution by Development of Fluorine-Free Battery Electrolyte

    Författare :Elham Hosseini Bab Anari; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sodium-ion batteries SIBs ; aqueous electrolyte; lithium-ion batteries LIBs ; safer electrolyte; fluorine-free salt;

    Sammanfattning : Portable electronic devices such as mobile phones, laptops, cameras and electronic vehicles (EVs) which contain lithium-ion batteries (LIBs), are indispensable part of our modern society. The safety of conventional electrolytes of LIBs, composed of fluorinated lithium salts and organic solvents is the source of some concerns. LÄS MER
