Theoretical analysis and Computer simulations have proven to be cost-effective and powerful tools in scientific studies of materials, particularly at nano-scale where synthesis of nano-structures, interpretation of their observed character and exploration of new structures are not always straight forward. We present here fundamental principles of techniques used today for computational simulati...

The definition of wear has been proposed as a progressive loss of materials due to mechanical action of two bodies while in contact. Several researchers have also suggested the definition of wear as the progressive loss of substance from the operating surface of a body occurring as a result of relative motion against a solid, liquid or gaseous counter body at the surface. Thus, it can be stated...

Studying the properties of structures where at least one spatial dimension is on the nanometer scale is motivated by many factors from engineering (such as the semiconductor industry’s push towards higher density integrated circuits), chemistry (developing methods to produce particles of well controlled size and structure), biology (using DNA to control the self-assembly of small structures) an...

Transport experiments in strong magnetic fields show a variety of fascinating phenomena like the quantum Hall effect, weak localization or the giant magnetoresistance. Often they originate from the atomic-scale structure inaccessible to macroscopic magnetotransport experiments. To connect spatial information with transport properties, various advanced scanning probe methods have been developed....

In this paper, a teleoperated nano scale object manipulation system is proposed, and requirements of such systems are defined. The system consists of a user interface utilizing visual and haptic displays (macro world), nano-manipulator, controller and sensors (nano world), and teleoperation control and rough to fine imaging and actuation tools (between macro and nano worlds). A home-made Atomic...
