  3. 2. Synthesis and Characterization of NCN Pincer Nickel Complexes

    University essay from Lunds universitet/Kemiska institutionen

    Author : Joel Klarén; [2023]
    Keywords : Pincer complexes; Nickel; organometallic chemistry; synthesis; NCN Pincer Nickel Complexes; organic chemistry; Chemistry;

    Abstract : In this work, a series of nickel NCN complexes and ligands have been synthesized with the goal of determining whether they can perform so-called CO2-insertion reactions into Ni-C bonds. So far, only the synthesis of the Ni-Br precursor complexes to the previously mentioned Ni-C complexes have been synthesized. READ MORE

  4. 3. Synthesis and analysis of potential metabolites of ADB-5´Br-BUTINACA

    University essay from Linköpings universitet/Kemi

    Author : Alaa Malekshahineia; [2023]
    Keywords : metabolites; NPS; synthetic cannabinoids;

    Abstract : In recent years, there has been a rise in the use of New Psychoactive Substances (NPS) that mimic the effects of controlled drugs and licensed medicines, which have become a significant public health concern globally. Synthetic cannabinoids, a rapidly expanding category of NPS, with much higher potency and binding affinity to the cannabinoid receptors than ∆9-tetrahydrocannabinol (THC), have led to serious psychiatric complications and other adverse effects.

  5. 4. X-Ray Fluorescence of Metal Halide Perovskites

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

    Author : Samuel Narciso Silva; [2022]
    Keywords : Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Abstract : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. READ MORE

  6. 5. First Principles Studies Of 2D Magnets

    Author : Yahya Fayazi; Linus Jacobsson; Folke Gustafsson; [2022]
    Keywords : 2D material; ab initio; magnet; Quantum Espresso; Density Functional Theory; DFT; CrCl3; CrBr3; CrI3; 2D material; 2 dimensionella material; två dimensionella material;

    Abstract : The aim of this project is to examine the electric and magneticproperties of three monolayer chromium trihalides when doped withdifferent transitions metals, that is CrXY_6, where X=(Mn,Fe,Co,Ni,V)and Y=(Cl,Br,I). The calculations were made using the software programQuantum Espresso that used density functional theory to solveSchrödinger’s equation. READ MORE
