  5. 3. Computational prediction of novel MAB phases

    Author : Adam Carlsson; Johanna Rosén; Denis Music; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The synthesis procedure of any materials system is often considered a challenging task if performed without any prior knowledge. Theoretical models may thus be used as an external input and guide experimental efforts toward novel exotic materials which are most likely to be synthesizable. READ MORE

  6. 4. Tuned acidity in zeotypes: A descriptor to unravel the direct conversion of methane to methanol

    Author : Simone Creci; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; methanol; MFI; zeolite; methane; catalysis; infrared spectroscopy; zeotype;

    Abstract : The catalyst's acidity is crucial in countless chemical reactions, and thus to tune this parameter means to take the lead on the desired catalytic reaction. Therefore, it is not surprising that zeolites have been used since decades as catalysts for their outstanding properties of solid acids. READ MORE

  7. 5. Microstructure of a cubic boron nitride tool material and its degradation during hard turning operations

    Author : Jenny Angseryd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDX; adherent layer; cBN; PCBN; SEM; TEM; EELS and APT; wear; EFTEM;

    Abstract : Abstract. Polycrystalline cubic boron nitride (PCBN) materials are widely used in turning operations of hardened steels due to their beneficial mechanical properties like maintained high hardness at elevated temperatures, adequate toughness and for being more chemically stable towards iron compared to diamond at temperatures typical for turning operations.
