  4. 3. Surface modification of inorganic materials with graphene oxide : From solution to high-temperature synthesis

    Författare :Simon Tidén; Ulf Jansson; Mamoun Taher; Erik Lewin; Lars Nyborg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphene oxide; Coatings; Additive Manufacturing; Laser Powder Bed Fusion; Reactive Hot Pressing; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The use of graphene as an additive in materials is often challenging due to the agglomeration of the two-dimensional graphene sheets. An alternative additive is graphene oxide (GO), an oxidized form of graphene, which is easily dispersed in water. LÄS MER

  5. 4. Synthesis and Characterization of New Inorganic Thermoelectric Materials

    Författare :Daniel Cederkrantz; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; thermal conductivity.; Ba8Ga16Ge30; Seebeck coefficient; nanoinclusions; Thermoelectricity; waste heat recovery; clathrates; thermal stability; electrical resistance; Mg2Si; substitution; semiconductors;

    Sammanfattning : With thermoelectric materials it is possible to convert a difference in temperature into electrical energy. This can be utilized for a more efficient use of available energy, eg. by converting waste heat from a combustion process. LÄS MER
