Here we present a new class of active system, carbon nanotube-biopolymer composite actuators, which can easily overcome drawbacks of carbon nanotube bulky papers. In such a flexible and biocompatible composite, carbon nanotubes are only served as a highly conductive filler together with an ionic liquid in a chitosan matrix. The actuator adopts a bimorph configuration with the unform biopolymer-supported internal ionic liquid electrolyte layer sandwiched by two carbon nanotube electrode layers. Such an all-in-one combination of materials clearly shows a sizable reversible displacement in an atmosphere at low applied voltages was applied. Results of experimental investigations have shown the improvements achieved throughout the development process focusing on the voltage amplitude, frequency and moisture-determined displacement response, which shows the possibility of implementation of dry actuators in artificial muscle and micro-system products.

We present synthesis and in-situ doping of several important n-type and p-type compound semiconductor 1D nanomaterials via the chemical vapor deposition method, and the nanoelectroic and nanophotonic prototype devices based on these nanomaterials. Various high performance nanoelectroic devices, including metal-insulator-semiconductor field-effect transistors (FETs), metal-semiconductor FETs, and NOT, NOR and NAND logic gates based on FETs, have been fabricated and studied. Various NW (NB)/p+-Si heterojunction electroluminescence devices have been fabricated and studied. CdS NW ring cavities were fabricated and a straight CdS NW with Fabry-Pérot cavity structure was employed to couple the light out from the ring cavity.

Magnetorheological (MR) fluid, a suspension of synthesized nano-sized magnetic particle in non magnetic carrier fluid, was prepared and then their various characteristics were examined in this study. Magnetic particle was at first synthesized in a rather simple process of decomposition of penta carbonyl iron (Fe(CO)5) using oleyl amine and kerosene. Magnetic property and morphology of the synthesized nanoparticle were confirmed via vibration sample magnetometer (VSM) and transmission electron microscopy (TEM), respectively. MR fluid of nano-sized magnetic particle dispersed in a carrier fluid, was investigated under different external magnetic field strengths via a rotational rheometer. Their flow behaviors at a steady shear mode were examined under magnetic field strength.

We present the Quantum Dots (QDs) decorated single walled carbon nanotubes (SWNT) nanohybrids (QD-SWNT) for multimodal cellular imaging via optical imaging and magnetic resonance imaging (MRI).The QD-SWNT has been synthesized by covalently linking QDs onto chitosan-functionalized SWNT. Incubating human embryonic kidney (HEK) cell line 293T cells with QD-SWNT demostrates that the QD-SWNT shows highly intracellular labeling efficinecy and enhanced T2-weighted MRI signal. The higher intracellular labeling efficinecy compared to pure QDs can be attributed to the ability of SWNT to readily penetrate into cells and the enhanced T2-weighted MRI signal is the function of SWNT for lowering the transverse relaxation of water proton, which can acts as MRI contrast agent. Thus, QD-SWNT can serve as dual-modal MRI/optical imaging agent.

Conducting polymers have been extensively investigated using as electronic materials, while the control of the molecular arrangement in nanostructures as well as the nanostructures themselves is extremely important to improve their performance. Herein, we report a controllable synthesis of conducting polymer nanostructures. Firstly, we prepared helical conducting nanofibers with predominately one-handed helical conformation of polymers by a chemical polymerization. Secondly, a general electrochemical strategy was developed to synthesize vertically aligned conducting polymer nanostructures, including nanotubes and nanofibers.

Monodispersive FePt magnetic nanoparticles with hydrophobic ligand were chemically synthesized and with controllable surface-functional properties. In order to compare and select the high saturation magnetization of FePt nanoparticles, the synthesized solvents were changed to effectively increase magnetization due to the increased particle size and isolated distance of each nanoparticles. The surface modification of FePt nanoparticles by using mercaptoacetic acid (thiol) and 11-mercaptoundecanoic acid (MUA) as a phase transfer reagent through ligand exchange turned the nanoparticles hydrophilic, and the nanoparticles were water-dispersible. Transmission electron microscopy images indicate the nanoparticles slightly agglomerate after ligand exchange. FTIR spectra suggest that thiol and MUA bind to the FePt atoms of the surface, respectively.

An increasing number of technologies require large-scale integration of separately fabricated nano-objects into spatially organized, functional systems. Here we introduce an approach for dielectrophoresis and reserse transfer printing method. By doing these method we can easily get a nanowire bottom gate transistor with high performance. Firstly, nanowire bridge was formed simply by dielectrophoresis and then by reverse transferring of this bridge on the gate dielectric layer, a nanowire field effect transistor was fabricated. The on/off ratio, threshold voltage, field effect hole mobility, hole concentration and threshold swing of the transistor were measured by ∼6.6×106, −7.2V, 9.9cm2/V·s and ∼1.453×1016/cm−3, and 0.504V/decade.

An improved two-dimensional fractal analysis for internal rough surface of waveguide was presented in this paper to investigate the transmission power dissipation. Two approximate formulas were deduced to calculate the power dissipation of whole and partly roughness. After the simulation experiment by a BJ110 waveguide of the diplex filter, the results indicated that the surface density had little influence on power dissipation, while the influence of fractal dimension was very strong. Following the increase of surface roughness, the power dissipation would be also increased, and the maximum of the increase of power dissipation was 1.8 times than that of smooth surface.

One dimensional (1D) oxide nanostructures such as nanowires (NWs) are strategically important for both basic science and technological applications. These emerging nanomaterials have demonstrated superb physical properties. In particular, nanowires of wide band gap semiconductors are promising as building blocks in optoelectronic and transparent electronics, and doping with transition metals can result in ferromagnetism. Here we report on the synthesis of ZnO, In2O3 nanostructures and their doped counterparts. Their physical properties have been measured systematically and they show great potential in electronic and spintronic applications.
