  • Wear of sliding surfaces can occur by one or more wear mechanisms, including adhesive, abrasive, fatigue, impact, corrosive, and fretting. The wear rate, a measure of wear, generally needs to be minimized (Bhushan, 1996). As the dimensions of components and loads used continue to decrease (such as in microelectromechanical systems or MEMS), scratching/wear and mechanical properties at the micro- to

  • A large variety of nano- and microscale structures and devices, as well as NEMS and MEMS (systems integrate structures, devices, and subsystems), have been widely used, and a worldwide market for NEMS and MEMS and their applications will be drastically increased in the near future. The differences in NEMS and MEMS are emphasized, and NEMS are smaller than MEMS. For example, carbon nanotubes (nanostructure) can be used as the molecular wires and sensors in MEMS. Different specifications are imposed on NEMS and MEMS depending upon their applications.

  • Making microsystems at a scale level of few microns is called micromachining. Micromachining is used to fabricate three-dimensional microstructures. It is the foundation of a technology called Micro-Electro-Mechanical-Systems (MEMS). MEMS usually consist of three major parts: sensors, actuators, and an associate electronic circuitry that acts as the brain and controller of the whole system.

  • It is not so far from now, although it is just the end of the XX century, the time when we discussed outlooks of the use of biotechnologies in medicine and pharmacy. These hopes were connected mainly with new microbiological products and new materials (polymers) for pharmaceutics, biomedicine and organ transplantation. Now in the XXI century, we are much more enthusiastic about outlooks of nanotechnologies for our life and environment.

  • Polymer applications have become more demanding as industry continuously turns to more microscopic parts. Due to the interactions of the polymer chains with the supporting surface and the air interface, the thinner films required for such applications have distinctly different properties than those of the well-defined bulk systems. The goal of the current research is to elucidate the behavior of ultrathin films.
