1. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap
University essay from KTH/MaterialvetenskapAbstract : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

4. Evolution of the signal induced by ChemCam on Mars as a function of focus
University essay from Luleå tekniska universitet/RymdteknikAbstract : ChemCam, mounted on the mast of the Mars Science Laboratory (MSL) rover, uses Laser-Induced Breakdown Spectroscopy (LIBS) to perform remote-sensing science on Mars. ChemCam’s telescope is used to simultaneously focus the laser on martian rocks up to 7 meters away from the rover and collect the light emitted as the plasma plume created on the target cools down.

5. Classification of spectral signatures in biological aerosols
University essay from Institutionen för fysikAbstract : In this thesis multivariate methods were used to evaluate pretreatment methods, such as normalization, as well as classification possibilities of data collected with Laser Induced Breakdown Spectroscopy (LIBS). The LIBS system that FOI is currently developing for the purpose of classifying biological airborne threats was used to collect data from ten different samples in a laboratory environment. READ MORE
