  2. 21. Multivariate Measurements and Chemical Imaging of Organic Compounds

    Author : Johan Engelbrektsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Spectroscopy; Hyperspectral; Chemical Imaging; PCA; PLS; SERS; Wavelet Transform; Multivariate analysis;

    Abstract : Chemical imaging is an emerging analytical technique, based on the interplay between, most often, spectroscopic measurements and advanced evaluation methodology. With this we can study the distribution of chemical compounds in different compartments, such as individual cells and pharmaceutical tablets. READ MORE

  4. 22. Elucidating Chemical and Electrochemical Side-Reaction Mechanisms in Li-ion Batteries

    Author : Neeha Gogoi; Erik Berg; M. Rosa Palacín; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion battery; solid electrolyte interphase; electrolyte additives; reaction mechanism; ethylene carbonate; vinylene carbonate; tris trimethylsilyl phosphate; surface enhanced Raman spectroscopy; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : Lithium-ion batteries constitute a leading technology that plays a major role in the transition towards sustainable transportation and power generation. The stability of modern batteries relies on a passivation layer formed on the negative electrode known as the solid electrolyte interphase (SEI). READ MORE

  5. 23. Practical application of machine learning for analyses of biological matrices and environmental phenomena

    Author : Alexandra Walsh; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Machine learning; Surface enhanced Raman spectroscopy; Acute lymphatic leukaemia; Volatile halogenated organic carbons; Marine algae; Doxorubicin; Principal component analysis; Multivariate statistics; Design of experiments; Waterlogged archaelogical wood; Transposed orthogonal partial least squares;

    Abstract : This thesis presents research aimed at forwarding an understanding of machine learning methods as a method of studying complex matrices and environmental phenomena. A number of machine learning methods in the form of linear projection algorithms and statistical experimental designs were applied for qualitative analysis of different matrices. READ MORE

  6. 24. Resonant Interactions Between Nanoparticle Plasmons and Molecular Excitons

    Author : Gülis Zengin; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; surface-enhanced absorption; J-aggregates; Localized surface plasmon resonance; strong coupling; Rhodamine 6G; nanoparticles;

    Abstract : Molecular plasmonics involves the study and applications of plasmonic metal nanostructures interacting with molecules. It has been a basis for development of fundamental understandings of light-matter interactions as well as of new technologies, including biological and chemical sensors and plasmon-enhanced spectroscopies.

  7. 25. On the bone response to oxidized titanium implants. The role of microporous structure and chemical composition of the surface oxide in enhanced osseointegration

    Author : Young-Taeg Sul; Göteborgs universitet; []
    Keywords : Oxidized titanium implants; micro arc oxidation; oxide growth; surface oxide properties; bone; biomechanical tests; histomorphometry; enzyme histochemistry.;

    Abstract : Background: Titanium implants have been widely used clinically for various types of bone-anchored reconstructions. A thin native oxide film, naturally formed on titanium implants contacts with bone tissue and has been considered to be of great importance for successful osseointegration. READ MORE
