  2. 16. Ink Film Splitting Acoustics in Offset Printing

    Author : Joakim Voltaire; Per Claesson; Douglas Bousfield; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : This thesis claims a relationship between the film splitting sound emission from the printing press nip and the dynamic interaction occurring there between ink, fountain solution and substrate in offset lithography. The film splitting sound derives from the cavitation formed by the pressure drop in the second half of the print nip flow passage. READ MORE

  4. 17. Self Assembly at the Liquid Air Interface

    Author : Niga Petru; Rutland Mark; Ye Shen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; VSFS; SFG; interface; crown ethers; ethylene oxides; ionic liquids; fatty acids; domains.; Surface and colloid chemistry; Yt- och kolloidkemi;

    Abstract : The aim of this work is to study the interfacial properties of amphiphilic compounds at the liquid–air interface in an attempt to develop a comprehensive understanding of their orientation as well as the influence of their interaction with the solvent on the interfacial layer properties. Using Vibrational Sum Frequency Spectroscopy (VSFS) as the main tool, the molecular structure of the amphiphilic layer and the amphiphile–solvent relation can be illuminated in great detail – it is arguably the most sensitive surface spectroscopy currently available.

  5. 18. ASPECTS OF FLUID THERAPY: An experimental study of the effects of systemic inflammation, microvascular permeability, blood pressure and plasma volume

    Author : Maris Dubniks; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sepsis; activated protein C; SIRS; albumin; blood pressure; colloids; plasma volume; hypervolaemia; hypovolaemia; microcirculation; noradrenalin; permeability; prostacyclin;

    Abstract : Adequate circulating blood volume is a prerequisite for circulatory stability. Fluid therapy aims at correcting hypovolaemia, and is an important part of the haemodynamic management of perioperative and critically ill patients. READ MORE

  6. 19. Interaction Between Graphene Derivatives and Asphaltenes in Crude Oil and Crude Derivatives

    Author : Govindan Induchoodan; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micelle Structures; Material enhancement; Enhanced Roads; Graphene; Asphaltene deposition; Structure-Function;

    Abstract : The chemistry of crude oil (SARA) and crude derivatives, and the percentage of asphaltene can vary significantly depending on external and internal factors such as the source and method of SARA extraction. If graphitic materials are introduced into a system such as SARA, it becomes an additional variable to a complex multi-phase colloid. READ MORE

  7. 20. Colloidal carrier substances : Properties and impact on trace metal distribution in natural waters

    Author : Anna Ledin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Colloidal (0,45 J.Im) are important constituents in the aquatic environment, due to their impact on the mobility and bioavailability of associated components (e.g. metals). READ MORE
