  2. 1. Effects of Environment on Charge Recombination in Organo-Metal-Halide Perovskite Observed by Photoluminescence Microscopy and Spectroscopy

    Author : Jun Li; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environment; photoluminescence microscopy and spectroscopy; organo-metal-halide perovskite; charge recombination;

    Abstract : Organo-metal-halide (OMH) perovskites form a new class of materials withperovskite crystal structure ABX3 where A is an organic molecule, B is lead (Pb)and X is a halide atom (I or Br). OMH perovskite semiconductors have been widely used in photovoltaics due to their very strong absorption of sun light, very suitable electrical properties, and the ease of preparation. READ MORE

  4. 2. Direct Amino Acid-Catalyzed Enantioselective α-Oxidation Reactions and Asymmetric de novo Synthesis of Carbohydrates

    Author : Magnus Engqvist; Armando Cordova; Christina Moberg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organo catalysis; Organic chemistry; Organisk kemi;

    Abstract : The ability of amino acids to form nucleophilic enamines with aldehydes and ketones has been used in the development of asymmetric α-oxidation reactions with electrophilic oxidizing agents. Singlet molecular oxygen has for the first time been asymmetrically incorporated into aldehydes and ketones, and the products were isolated as their corresponding diols in good yields and ee’s.
