  2. 11. Study of novel electronic materials by mid-infrared and terahertz optical Hall effect

    Author : Nerijus Armakavicius; Vanya Darakchieva; Philipp Kühne; Mircea Modreanu; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Development of silicon based electronics have revolutionized our every day life during the last three decades. Nowadays Si based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. READ MORE

  4. 12. Binary mixtures and cationic modification of protic ionic liquids. Local structure and transport properties

    Author : Iqbaal Abdurrokhman; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nuclear magnetic spectroscopy; cationic modification; triazolium; imidazolium; proton mobility; Protic ionic liquids; vibrational spectroscopy; impedance spectroscopy; binary mixtures; synthesis;

    Abstract : Protic ionic liquids are a subclass of ionic liquids, which in many cases are obtained by mixing an equimolar amount of Brønsted acid and base. Protic ionic liquids possess an exchangeable proton that gives them distinct features, e.g. READ MORE

  5. 13. Amorphous Magnetic Materials : A Versatile Foundation for Tomorrow’s Applications

    Author : Sebastian George; Gabriella Andersson; Björgvin Hjörvarsson; Fridrik Magnus; Elizabeth Blackburn; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amorphous; Magnetism; Rare Earth; Transition Metal; RE-TM; Thin Film; TbCo; SmCo; FeZr; CoFeZr;

    Abstract : Amorphous magnetic materials exhibit a number of key differentiating properties with respect to crystalline magnets. In some cases, the differences may simply be in the values of macroscopic properties such as saturation magnetization, coercivity, Curie temperature, and electrical conductivity. READ MORE

  6. 14. Sub-grain structure in additive manufactured stainless steel 316L

    Author : Yuan Zhong; Zhijian Shen; Daqing Cui; Moataz Attallah; Stockholms universitet; []
