Topic: Development of Multifunctional Nanoparticles and Magnetic Immunoassay for Biochemical Applications
Abstract: Functional nanoparticles are important parts of nanotechnology and have been widely used for various applications of material science and biochemical analysis. The multifunctional nanoparticles have great potential to be used in many new applications. Magnetic immunoassay is a relative new and effective technique for bioanalysis. This presentation would show the recent development of functional nanoparticles and magnetic immunoassay for biochemical analysis. Several model biomarkers would be used to demonstrate the applications of this technique. In comparison with other methods, this method has lower detection limit and wider linear range. This technique has great potential to provide a simple, fast, sensitive, and selective analysis for particles, proteins, and other biomaterials.

Topic: Nickel Complexes-catalyzed Synthesis of Polyethylene Elastomers and Ethylene Polymerization in the Confinement of Mesoporous Molecular Sieves
Abstract: Polyethylenes (PEs) with varying branches play important roles in modern society. Metal complexes as pre-catalysts for ethylene polymerization and the introduction of inorganic confinement into ethylene polymerization are two predominant tools in fabricating PEs with improved performance. Firstly, there have been various nickel procatalysts for polymerization of olefin and cyclic olefins. In our research nickel precatalysts for ethylene polymerization have been achieved by bidentate nickel complexes with N^N ligands and O^P ligands. The PEs produced by the [N^N] Ni complexes affords high MWs, high branching degree and good elasticity whereas those formed with the [O^P] Ni complexes possess polar side chains.
Secondly, mesoporous molecular sieves (MMS) act as both the catalyst support and nanoreactor for ethylene polymerization. MMS, typically MCM-41 and SBA-15, offers suitable pore sizes for ethylene polymerizations to proceed in an extrusion mode in which the formation of polymeric nano-fibers composed of extended polymer chains from the nanopores of MMS is completed in one step. Moreover, the polyethylenes (PE) and ethylene copolymers (ECP) are in situ compounded with MMS particles to form polymer nanocomposites when the MMS framework collapses due to polymeric chain growth and/or enormous polymerization exotherms. This facile methodology endows the resultant PEs with significant advantages, such as increased MWs and MWD, elevated strength and modulus, and improved processability, etc..

Topic: Mechanisms of Porosity Encountered in Manufacturing Processes
Abstract: This lecture analyzes different mechanisms of porosity formation in solid. Porosity is susceptible to stress concentration, degrading properties of products in manufacturing and materials technologies. On the other hand, in view of good heat insulation, ice containing oxygen, nitrogen and ozone can be, respectively, used for fishery industries and food preservation and sterilization. Porous scaffold is conducive to tissue ingrowth in tissue engineering. Pore formation can be due to either a bubble entrapment or keyhole collapse during solidification. Pore formation due to a bubble entrapment can be analyzed by proposing a model accounting for species and momentum transport and physicochemical equilibrium at the cap of an entrapped bubble. This work finds that there exist three different cases for pore formation, depending on solidification rate and directions and magnitude of solute transfer across the cap. Pore formation due to keyhole collapse can be studied by proposing a model for a compressible flow through a keyhole of varying cross-section and its transition from annular to slug flows. Introducing the Young-Laplace equation, the predicted pore shapes in solid in both mechanisms agree with experimental data.

Topic: Advances and Opportunities of Solution-Based Process on Metal-Oxide-Semiconductor Devices
Abstract: The speech reviews and presents a discussion on native oxide on GaAs-based semiconductor materials through the solution-based process. Solution-based process is generally flexible, faster and less expensive as compared to vapor deposition methods. Neither anodic equipment nor an assisting energy source is needed in the solution-based system. Moreover, the speech will address how the solution-based process can be applied to fabricate a metal-oxide-semiconductor (MOS) gate of high-electron-mobility transistor (HEMT) with a larger gate voltage swing and lower leakage current density. Therefore, the use of solution-based process on GaAs-based materials provides new opportunities for device applications.
