   Sammanfattning : This thesis is a summary and discussion of eight papers dealing with failures and structural aspects of Ni-Cd industrial pocket plate batteries, applications of voltammetry in adsorption studies on goethite (a-FeOOH) surfaces and synthesis and characterisation of nanostructured carbons. The work consists of different areas of chemistry; electrochemistry, structural chemistry and solution chemistry. LÄS MER

3. 7. Nanostructured carbon materials under extreme conditions

   Författare :Mattias Mases; Fernando Rodríguez; Luleå tekniska universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

   Sammanfattning : The discovery of the Buckminsterfullerene in 1985 by Richard Smalley, Robert Curl and Harold Kroto opened an era of great interest to the exploration of nanostructured carbon materials. These materials come in many forms and are often categorized by their dimensionality. Graphene is an ideal 2-dimensional (2D) sheet of sp2-bonded carbon atoms. LÄS MER

4. 8. Nanostructures of Graphite and Amorphous Carbon - Fabrication and Properties

   Författare :Hans Fredriksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optical resonance; Raman-spectrum; carbon; optical spectrum; HOPG; GC amorphous carbon; oxidation; Nanofabrication;

   Sammanfattning : Nanoscience is a well-established research area, which concerns properties and fabrication of objects with typical dimensions on the 1-100 nanometer length scale. A central issue has been the development of techniques for fabrication and characterization of nanometer sized objects, which have contributed considerably to progress in both practical applications and fundamental research.
