The aim of this paper was to present the synthesis, characterization and application of the Fe3O4 - chitosan composite as potential adsorbent for removing lead ions from industrial wastewater. The nanocomposite nanomaterial was characterized by XRD and SEM analyzes. The influence of some parameters (pH of wastewater, lead ions concentration and dose of Fe3O4 - chitosan absorbent) upon the efficiency of wastewater treatment were investigated. The Pb (II) ions concentrations in wastewater were 0.5, 1, 1.5 and 2 mg/L. The amounts of Fe3O4 - chitosan nanocomposite adsorbent tested were 0.05, 0.1 and 0.2 g. In some experimental conditions, Fe3O4 - chitosan nanocomposite adsorbent leaded to obtaining of 100% wastewater treatment efficiency.

The fabrication and the property investigation of the hybrid nanocomposite material made of poly[2-methoxy-5-(2′-ethyl-hexyloxy)-1,4-phenylene vinylene] (MEH-PPV) polymer and Y3Al5O12:Ce (YAG:Ce) with the relative weight ratio of 1 : 1 in order to apply for optoelectronic devices are reported. Thermal analysis showed the hybrid material’s deterioration or decomposition when the temperature exceeded 200°C under inert gas atmosphere. Rheological measurement concluded that the material solution can be used for spinning or soft moulding lithography making large- or flexible substrate surface. Optical properties of the hybrid material are investigated. The effect of thermal treatment on the optical properties showed that, at 180°C under inert gas environment, the optical properties were enhanced. An MEH-PPV/YAG:Ce hybrid nanocomposite converted LED lamp was fabricated showing that the hybrid material is suitable as conversion material for white LED fabrication.

Developement of computer technology provides much improvements on electron microscopy, such as simulation of images, reconstruction of images and automatic controll of microscopes (auto-focussing and auto-correction of astigmatism) and design of electron microscope lenses by using a finite element method (FEM). In this investigation, procedures for simulating the optical properties of objective lenses of HREM and the characteristics of the new lens for HREM at 200 kV are described.The process for designing the objective lens is divided into three stages. Stage 1 is the process for estimating the optical properties of the lens. Firstly, calculation by FEM is made for simulating the axial magnetic field distributions Bzc of the lens. Secondly, electron ray trajectory is numerically calculated by using Bzc. And lastly, using Bzc and ray trajectory, spherical and chromatic aberration coefficients Cs and Cc are numerically calculated. Above calculations are repeated by changing the shape of lens until! to find an optimum aberration coefficients.
