5. 3. A Topographic Study of Functional Surfaces

   Author : Robert Ohlsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder bore; 3D surface roughness; topography; expert system; AFM; relocation; replication; instrumentation; functional demands;

   Abstract : Surface topography through the years has taken on increased importance, because of the rise in quality demands. The surface often has to meet additional functional demands when products become more complex in accordance with customer preferences. READ MORE

6. 4. Mechanical properties of carbon nanotubes and nanofibers

   Author : Henrik Jackman; Krister Svensson; Pavel Krakhmalev; Håkan Olin; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atomic force microscopy; bending; carbon nanotubes; deformation; scanning electron microscopy; Young s modulus; carbon nanofibers; mechanical properties; Physics; Fysik;

   Abstract : Carbon nanotubes (CNTs) have extraordinary electrical and mechanical properties, and many potential applications have been proposed, ranging from nanoscale devices to reinforcement of macroscopic structures. However, due to their small sizes, characterization of their mechanical properties and deformation behaviours are major challenges. READ MORE

7. 5. Surface nanomechanical properties of hydrogels and coatings

   Author : Gen Li; Per M. Claesson; Jan van Stam; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanomechanical properties; nanotribology; nanowear; poly-HEMA; poly-NIPAm; Cellulose nanocrystals; AFM; Kemi; Chemistry;

   Abstract : Characterizing mechanical and wear properties at the nanometer scale emerged as a fascinating and challenging topic in the last decades due to recognition of many interesting and unusual properties of nanomaterials. Due to recent developments of the atomic force microscopy (AFM) technique, it is now possible to measure nanomechanical properties and topography simultaneously, as well as performing and evaluating wear measurements at the nanometer scale.
