   Abstract : The main objective of nanotechnology is to build self-powered nanosystems that are ultrasmall in size, exhibit super sensitivity, extraordinary multi functionality, and extremely low power consumption. As we all know that 21st century has brought two most important challenges for us. One is energy shortage and the other is global warming. READ MORE

5. 13. Atomically Resolved ac-Mode Atomic Force Microscopy in Ultra-High Vacuum

   Author : Lars Olsson; Franz Giessibl; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : When the atomic force microscope (AFM) was invented in 1986, it was anticipated that the technique should be able to produce atomically resolved images with aquality similar to what was routinely obtained with the scanning tunnelling microscope (STM). Even though the AFM quickly became a very popular technique, the development toward ultra-high resolution imaging turned out to be slow due to problems of both fundamental and technical nature.

6. 14. 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. 15. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

   Author : Petra M Hansson; Per M. Claesson; Agne Swerin; Adam C Simonsen; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

   Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.
