    Keywords : Raman spectroscopy; brain tumor; diagnosis;

    Abstract : Brain tumors or brain cancer is a disease than affects people of all ages. The median age of a person living with a brain tumor is 60 years, it is however a disease that affects children and young adults in high grade. READ MORE

  3. 2. Effect of iron redox state on crystallization behaviour of Fayalite slags

    University essay from KTH/Materialvetenskap

    Author : Paolo Mai; [2020]
    Keywords : Copper smelting; Slag; Magnesium Oxide; Iron redox equilibria; Optical basicity; Raman spectroscopy.; Smältning av koppar; Slagg; Magnesiumoxid; Järnredoxjämvikt; Optisk basicitet; Ramanspektroskopi.;

    Abstract : In the copper smelting processes, the viscosity of the matte and the slag is an important factor for establishing efficiency. Impurities in the concentrates affect the viscosity not only by changing the melt structure but also by promoting precipitation of solid phase which sharply rises it. READ MORE

  4. 3. Optical Characterization of Lignin Nanoparticles

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kristoffer Linder; [2020]
    Keywords : lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

    Abstract : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. READ MORE

  5. 4. FTIR- och Ramanspektroskopi som analysmetod för den kemiska sammansättningen av granved : en jämförelse

    University essay from SLU/Dept. of Forest Ecology and Management

  6. 5. Tactile resonance method for measuring stiffness in soft tissue - evaluation of piezoelectric elements and impression depth using a silicone model

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tobias Tovedal; [2017]
    Keywords : Tissue stiffness; Resonance sensor; Prostate cancer; Piezoelectric; Tactile sensor;

    Abstract : An instrument is being developed at the Department of Biomedical Engineering; Research and Development (MT-FoU), at the University Hospital of Umeå with the aim to detect prostate cancer ex vivo. Using a combination of tactile resonance technology and Raman spectroscopy the instrument is intended to be used in the operating room during radical prostatectomy to identify positive surgical margins.
