  • This book is a collection of some of the invited talks presented at the international meeting held at the Max Planck Institut fiir Physik komplexer Systeme, Dresden, Germany during August 6-30, 2001, on the rapidly developing field of nanoscale science and bio-electronics (http://www.mpipks-dresden.mpg.de/~nanobio/). Semiconductor physics has experienced unprecedented developments over the second half of the twentieth century. The exponential growth in microelectronic processing power and the size of dynamic memories has been achieved by significant downscahng of the minimum feature size.

  • HPDE-clay composites materials prepared by melting compounding have discrete change in mechanical physical properties in comparison to the initial HPDE even when a small amount of clays is introduced. It is presented the results of the studying of the structure, the properties and morphology of HPDE- clay composites. The E modulus is increased from 702 MPa in the initial to 993.34 MPa, the tensile strength is raised from 12.37 to 35.33 MPa (most 3 times) and solvent permeability is decreased with 1% clay.

  • The ZnO nano-tetrapods have been prepared by the evaporation of metallic Zn powder at the temperature range of 700oC- 950oC in air. The influence of experimental conditions, such as the evaporation temperature and the substrate temperature, on the morphology, the size and the photoluminescence (PL) was investigated. The XRD pattern showed that the nano–tetrapods were ZnO with hexagonal structure. The branch size of the tetrapods was about two hundreds nanometers.

  • Tools shape how we think; when the only tool you have is an axe, everything resembles a tree or a log. The rapid advances in instrumentation in the last decade, which allow us to measure and manipulate individual molecules and structures on the nanoscale, have caused a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details underlying interfacial phenomena have customarily been inferred from in situ measurements of macroscopic quantities. Now we can see and “finger” physical and chemical processes at interfaces.

  • Boundary films are formed by physical adsorption, chemical adsorption, and chemical reaction. The physisorbed film can be either monomolecular or polymolecular thick. The chemisorbed films are monomolecular, but stoichiometric films formed by chemical reaction can have a large film thickness. In general, the stability and durability of surface films decrease in the following order: chemical reaction films, chemisorbed films, and physisorbed films. A good boundary lubricant should have a high...

  • The new millennium has seen the birth of a new perspective that conflates research in solid-state physics, biological science as well as materials engineering. The perspective is one that recognizes that future new advances in all these areas will be based on a fundamental understanding of the atomic and molecular infrastructure of materials that has resulted from two centuries of chemistry. Major advances will be achieved when the novel behavior, in particular the quantum mechanical behavior, that nanoscale structures possess, can be controlled and harnessed....
