  2. 16. Exploring the surface of aqueous solutions : x-ray photoelectron spectroscopy studies on a liquid micro-jet

    Author : Josephina Werner; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The surface behavior of biologically or atmospherically relevant chemical compounds in aqueous solution has been studied using surface-sensitive X-ray photoelectron spectroscopy (XPS). The aim is to provide information on the molecular-scale composition and distribution of solutes in the surface region of aqueous solutions. READ MORE

  4. 17. Photophysics of Perovskite Nano- and Microcrystals

    Author : Junsheng Chen; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ultrafast spectroscopy; Two-photon absorption; Perovskite; Nanocrystals; Photostability; Lead free perovskite;

    Abstract : The demand and consumption of energy is increasing dramatically all around the world. Broad adoption of fossil fuels has triggered an enormous threat to the environment. To ensure sustainability of our species and habitat, new solutions to fulfill the energy demand have to be found. READ MORE

  6. 19. Physical characterization of exosomes and other extracellular vesicles using surface-based sensing

    Author : Deborah Rupert; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoparticle tracking analysis; exosomes; scattering; surface-based biosensing; optical density; cluster of differentiation 63 CD63 ; liposomes; label-free; fluorescence; surface plasmon resonance; Extracellular vesicles; specificity; antibody; lipid content; single particle; quantification; size distribution; optical waveguide microscopy;

    Abstract : Extracellular vesicles (EVs) are hundred of nanometer sized particles secreted by almost all cell types. Exosomes are one type of EVs today intensively investigated due to the increased evidence suggesting that they play important roles as communicating vehicles in a broad range of physiological processes, pathological conditions and disease diagnostics.

  7. 20. Relict non-glacial surfaces and autochthonous blockfields in the northern Swedish mountains

    Author : Bradley W. Goodfellow; Arjen Stroeven; Clas Hättestrand; Johan Kleman; Krister Jansson; Adrian Hall; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; blockfield; chemical weathering; cosmogenic exposure dating; glaciated landscape; northern Sweden; periglacial geomorphology; relict surface; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Geography; Physical Geography;

    Abstract : Relict non-glacial surfaces occur in many formerly glaciated landscapes, where they represent areas that have escaped significant glacial modification. Frequently distinguished by blockfield mantles, relict non-glacial surfaces are important archives of long-term weathering and landscape evolution processes. READ MORE
