Abstract: Size effect for intrinsic stresses and thermodynamics of films formation established taking into account the nature of stresses in copper condensates deposited on solid state substrates. We believe that surface energy changes during layer by layer deposition in such condensates with chaotically dispersed areas (possessing different values of Young’s modulus) define the film’s mechanic parameters. The quantitative estimations of mechanical stresses are calculated for layer by layer film growth. The resulting intrinsic stresses (ISs) in copper condensates nature from local static ones, superposed within the area of a film. The latter arose due to anisotropy of interface interaction energy parameters.

Abstract: Against for a series of problems with the currently existing of bad modifiability and reusability for the traditional user interface development method, first propose a general-purpose interface automatically generated model--GIAGM, including interface configuration, interface customization, interface generating, the interface control and interface management mechanism, further put forward a interface interaction method based on message control. Research work to achieve an XML-based general-purpose interface automatically generated system. The application of the system not only allows the software development easier and faster, but also easy to maintain. Finally, the instance is introduced for the interface automatically generated system has good scalability and customization capabilities, can reduce the complexity of the interface development, improve the efficiency of the development.

Abstract: The nature of interface plays a very important role in the properties of nanoparticle-reinforced polymer nanocomposites. Understanding the interfacial interactions is crucial in further development of such nanocomposites. In this work, density functional theory is used to examine the interfacial interactions in the clay-nylon 6 nanocomposites. In particular, comparison has been made the systems in the absence of surfactant and in the presence of surfactant. It is found that surfactant can enhance the interfacial interactions through the formation of hydrogen bonds with clay surface and nylon 6. The interaction energies among the different components are calculated for the systems with clay of different atomic substitution.

Abstract: Interfaces are important for many properties and applications of multiphase materials. This is particular true for particle-reinforced polymer composites, where the interfacial characteristics between particle and polymer play a crucial role in load transfer and mechanical properties. In polymer nanocomposites, the adhesion strength between particle and polymer matrix is a major factor in determining their mechanical properties. In this work, we present our recent study towards the quantification of the interaction strength at the interface of clay-based polymer nanocomposites by molecular dynamics simulation.
