  1. 1. Alkylglucosides - physical chemical properties

    Författare :Frederik Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER

  2. 2. Synthesis and Characterization of Carbon Based One-Dimensional Structures : Tuning Physical and Chemical Properties

    Författare :HamidReza Barzegar; Thomas Wågberg; Hans Kuzmany; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Carbon Nanotube; single-walled carbon nanotube; nitrogen doped; chemical vapor deposition; fullerene; hybrid structures; nanomaterials; nanomaterial;

    Sammanfattning : Carbon nanostructures have been extensively used in different applications; ranging from electronic and optoelectronic devices to energy conversion. The interest stems from the fact that covalently bonded carbon atoms can form a wide variety of structures with zero-, one- and two-dimensional configuration with different physical properties.

  3. 3. Physical properties of chromospheric features : Plage, peacock jets, and calibrating it all

    Författare :Alexander G. M. Pietrow; Dan Kiselman; Jaime de la Cruz Rodríguez; Malcolm Druett; Gianna Cauzzi; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Sun; chromosphere; plage; jets; imaging; spectropolarimetry; Astronomy; astronomi;

    Sammanfattning : The chromosphere is a complex and dynamic layer of the solar atmosphere, largely dominated by the local magnetic field configuration. It acts as an important interface between the photosphere below it and the hot corona above. However, studying this layer is not straightforward, as it is largely transparent in optical wavelengths.

  4. 4. Multi-dimensional imaging : A tool to unravel material properties at the nanoscale

    Författare :Boris Louis; NanoLund: Center for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Optical microscopy; Fluorescence Microscopy; Multi-dimensional imaging; Material sciences; Optical Trapping; Single-molecule imaging and tracking; Single-molecule spectroscopy;

    Sammanfattning : Optical microscopy has revolutionized the way we understand our world and has become a crucial tool in a range of disciplines such as biology, physics, chemistry, and material sciences. The development of new microscopy techniques has been capital to its success and wide applicability. LÄS MER

  5. 5. Materials prepared using graphite oxides : properties and applications

    Författare :Artem Iakunkov; Aleksandr V. Talyzin; Josef Breu; Umeå universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Graphene oxide; Activated Graphene; Swelling; Supercapacitor; Sorption of radionuclides; Materials Science; materialvetenskap; fysik; Physics;

    Sammanfattning : Graphite oxides are hydrophilic materials, which have attracted a lot of attention due to unique properties and possible applications. The current thesis includes studies of fundamental properties and applications of graphite oxides as well as materials prepared from graphite oxides such as graphene oxide membranes, defect-rich graphite oxide, reduced graphene oxide and activated reduced graphene oxide.
