  3. 7. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Linnea Lindh; [2019]
    Keywords : Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Abstract : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions.

  5. 9. Making wood durable. A sustainable approachwith linseed oil

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Helena Olsson; [2019]
    Keywords : Linseed oil; Wood preservation; Nuclear Magnetic Resonance NMR ; Diffusion Ordered Spectroscopy DOSY ; Time-resolved oxidation study; Linolja; Bevarande träbehandling; Nuclear Magnetic Resonance NMR ; Diffusion Ordered Spectroscopy DOSY ; Oxidationstidsstudie;

    Abstract : Linseed oil has been and is used for vast number of applications, such as in food and paint industry, and wood preservation. It is a good environmental choice, as it originates from renewable sources. Linseed oil is mainly a mixture of triglyceride of fatty acids, both saturated and mono- or polyunsaturated, which allows the oil to oxidize. READ MORE

  6. 10. All solid state single-shot Dispersion scan (D-Scan) for ultrashort laser pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Shekhar Jadhav; [2019]
    Keywords : Dispersion scan; d-scan; Single shot d-scan; Si-scan; Physics and Astronomy;

    Abstract : Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. READ MORE
