  1. 1. Synthesis and Characterization of Copper Halide Complex Materials

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Hiroki Tomita; [2021]
    Keywords : Copper halide complexes; Coordination polymers; Photoluminescence; Bidentate ligands; Applications of thin films; Kopparhalogenidkomplex; koordinationspolymerer; fotoluminiscens; bidentata ligander; tillämpningar av tunna skikt;

    Abstract : Energiförbrukning är ett hett ämne i världen idag, eftersom världens befolkning fortsätter att växa. Som ett resultat ökar också den globala energiförbrukningen snabbt och utsläppen av koldioxid därmed, vilket påverkar global uppvärmning och klimatförändringar. READ MORE

  3. 2. On the Relationship Between Energetic Electron Precipitation and Mesopause Temperature

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Florine Enengl; [2019]
    Keywords : ;

    Abstract : Energetic Particle Precipitation (EPP) can potentially change the neutral atmospheric temperatureat the mesopause region. Cresswell-Moorcock et al. (2013) used European IncoherentScatter Scientific Association (EISCAT) radar data to identify strong electron precipitationevents. READ MORE

  4. 3. Electron cooling in a cometary coma

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Simon Alinder; [2017]
    Keywords : Comet; Plasma; Inner coma;

    Abstract : The ESA Rosetta spacecraft investigated comet 67P/Churyumov-Gerasimenko duringtwo years from August 2014 to the end of September 2016. The dual Langmuir probewas used to measure plasma parameters including the thermal energy of theelectrons. READ MORE

  5. 4. WC grain size distribution during sintering of WC-Co cemented carbides

    University essay from Lunds universitet/Materialteknik

    Author : Oscar Bjäreborn; [2016]
    Keywords : hardmetal; cemented carbides; WC; EBSD; grain size distribution; microstructure; coercivity; hardness; toughness; sintering; growth inhibition; Technology and Engineering;

    Abstract : The grain growth of WC in WC-7%Co cemented carbides with Cr-addition was investigated for cemented carbides synthesized from four different raw materials varying in grain size. Cr additions were 4%of the Co binder phase. To investigate the effect of Cr on grain growth two of the raw materials were also synthesized without Cr-additions. READ MORE

  6. 5. Population Oscillations in Excited Argon Atoms Initiated by Attosecond Pulses

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

    Author : Anna Olofsson; [2016]
    Keywords : Atomic Physics; Attosecond Physics; Population Transfers; Physics and Astronomy;

    Abstract : This project aims to study the process of electron excitation by a light pulse, a process at the core of many important contemporary and possible future devices. Data from an experiment where the electron dynamics is probed with attosecond laser pulses are analyzed in order to gain insight on the rapid population oscillations within the excited atomic system and simulations are constructed with the goal of mimicking structures found in the experimental data.
