This paper presents an imaging system for high-throughput magneto-optical (MO) Kerr effect characterization of combinatorial materials libraries, which allows an efficient way to measure the Kerr rotation of all samples in a materials library. A laser was used as the light source to achieve high signal-to-noise ratio, and a charge coupled device was used to record the MO images so that we can get the Kerr rotation of every sample in the library simultaneously. Reasonable spatial resolution and high sensitivity for high-throughput characterization were also demonstrated.

Most rollover accidents involve articulated engineering vehicle due to the center of gravity shift when steering. In this paper, a virtual prototype model of a loader as the typical articulated engineering vehicle is built using multi-body dynamics software. The dynamic simulation of steering characteristic under different slop and speed is made and the roll stability is analyzed. The stable working range of the loader obtained from the simulation results can give reference for the drivers selection of vehicle route and safe operation. This paper has a certain meaning for further study of articulated vehicles roll stability.

Nanorods of Ni/Fe complex metal hydroxides precursor were fabricated by a microemulsion method. The nanorods were 20~30 nm in diameter and 600~1000 nm in length, with amorphous structure. Ni/Fe composite oxides were obtained by calcinations of Ni/Fe complex metal hydroxides precursor. At 500 °C, the sample retained the morphology of the nanorods, with the same diameter to the precursor and the length shortened to 300~400 nm. The crystal phase was composed of NiO and dispersed amorphous Fe2O3. When the calcination temperature was higher than 500 °C, the morphology of the nanorods of the precursor were collapsed to nanoparticles, and the crystal phase transformed to the mixture of NiO and NiFe2O4.

Ni/poly(m-toluidine)(PMT) nanocomposites were prepared by in situ chemical oxidative polymerization of m-toluidine (MT) monomer in the presence of Ni powder, with ammonium persulfate (APS) as oxidant and citric acid (C6H8O7) as dopant. The resultant products were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC) and superconducting quantum interference device magnetometer (SQUID). The results exhibited that Ni/PMT nanocomposites show a ferromagnetic behavior with saturation magnetization strength (Ms) and coercivity of 28.4emu/g and 105.8Oe at room temperature. The prepared Ni/PMT composites were soft and ferromagnetic materials. Moreover, thermal Stability of nanocomposites was also investigated.
