This paper introduced the fundamental principle of the simultaneous desulfurization and denitrification by combining ozone oxidation and the NaOH double alkali method. And the total chemical reaction equations were achieved by analyzing the process of the absorption of the productions of ozone oxidation by NaOH double alkali method. Then, based on thermodynamic principle, the partial pressure of SOx, NOx and CO2 when reactions reached equilibrium were calculated respectively. This paper also studied the reaction mechanism of the absorption of SOx and NOx and analyzed the absorption characteristic of SOx and NOx in absorption solution. The results showed that the simultaneous desulfurization and denitrification by combining ozone oxidation and NaOH double alkali method was feasible. Not only the elimination ratio of SOx and NOx were almost up to 100%, but also CO2 was removed on a considerable scale. The partial pressure of SOx and NOx was very important to the pH value of the absorption solution which affected the elimination ratio of SOx and NOx greatly.

A hybrid process coupling reverse osmosis (RO) with electrodeionization (EDI) was investigated to remove TDS and boron from simulated seawater in this study. The effects of applied total dissolved solids (TDS) and the concentration of boron in the feed water on product water quality were investigated.

We got good results after applying the new type emulsifier in acrylic emulsion polymerization.

Laser-MAG hybrid, GMAW and SAW welding experiment were carried out for the new low CE 600MPa grade steel, and hardness survey on the welded joints was performed. Laser-MAG hybrid welding has the highest speed with the least filling weld metal, and its joint exhibits almost no softening with higher harness in weld than base metal. SAW welding has high efficiency but most significant softening effect on the HAZ. For SAW, on the HAZ 4 ~ 5 mm apart from the fusion line peak hardness exists. For GMAW, on the HAZ about 2mm away from the fusion line a softened zone appears, but the softening degree is lower than for SAW. The results showed that the hardness of the welded joint of this type of steel seems much subjected to the welding heat input.

A novel multibranched nonlinear dye，4, 4´, 4´´-tris(9-carbazyl-trans-styryl) triphenylamine (TCSTPA)，has been designed and synthesized aimed at two-photon absorption applications. Two-photon absorption cross section of the multibranched dye was obtained as high as 2.35×10-47cm4s photon-1molecule-1pumped with femtosecond laser beam at 800 nm. One-photon and two-photon absorption optical properties were demonstrated in solutions. Three-dimensional (3D) optical data storage experiments were carried out by two-photon photobleaching in the multibranched-dye doped polymethylmethacryate (PMMA) with a 3D data storage density of approximate 14 Gbits/cm3. Research on the two-photon photobleaching ability shows the novel two-photon absorption dye with multibranched molecular motif has higher photosensitivity than traditional linear two-photon absorption dyes do.

An experimental investigation was performed on fatigue crack growth behavior of a 16MnR pressure vessel steel. Standard compact tension (CT) specimens with three specimen thicknesses and notch sizes were subjected to Mode I constant amplitude loading with several stress ratios and loading amplitudes. The results revealed that the stress ratio had an insignificant influence on the fatigue crack growth of the material. The stable fatigue crack growth rate (FCGR) was accelerated as specimen thickness increased. The fatigue crack was extended in terms of the curve crack shape. The crack front at the surface was retarded compared to that at the interior along thickness direction, and the crack front at the mid-thickness plane reached the maximum value of the crack length. The similar curve crack shape was obtained in the stable crack growth stage. The maximum difference of the crack front along thickness direction was increased with the increasing of the specimen thickness. The early crack growth from the notch was effected by the size of the notch, the stress ratio and loading amplitude.

New initiator of FFM6 is used to initiate the acrylic emulsion polymerization. The influences of concentration of FFM6 (c[I]) and polymerization temperature (T) on polymerization reaction rate (Rp) were discussed. Rp is proportional to (c[I])1.4 which is different with classical emulsion polymerization whose Rp is proportion to (c[I])0.4, that indicate polymerization mechanism of the reaction in the study is different with classical mechanism. The value of Ea, 56.4 kJ/mol, is lower than the value of general radical polymerization’s Ea (80.0-96.0 kJ/mol), which indicates the FFM6 can initiate acrylic emulsion polymerization at a lower temperature compared with the other kinds of initiator.

In this paper, flame retardant Polyamide 6 (PA6) composites were prepared by nano-magnesium hydroxide (NMH) or its composites with melamine cyanurate(MCA) and ammonium polyphosphate(APP). Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to analyze the structure of nano-magnesium hydroxide. The properties including tensile properties, molten index (MFI), rockwell hardness and density of flame retardant PA6 were analyzed. Orthogonal experiments were used to study flame retardancy of PA6 with NMH, MCA and APP. The results showed NMH had hexagonal orthorhombic crystal structure with size of 300×200×100nm. Density of polyamide 6 showed an upward trend when the content of NMH was increasing, the mechanical properties and hardness changed little while processing performance serious declined. The flame retardance of nitrogen-phosphorus -inorganic flame retardants was not desirable.

The generation of ozone is efficient by using short high-voltage combined with a dielectric layer placed adjacent to the outer electrode in dry air. Ozone concontration depend on the peak pulsed voltage, pulse repetition rate, gas flow rate, reactor length and so on. For ozone generation by pulsed streamer discharge in dry air, a mathematical model, which describes the relation between ozone concentration and these parameters that are of importance in its design, is developed according to dimensional analysis theory. The presence of nitrogen on ozone formation in dry air cannot only consume high energy electron but also form nitrogen oxides (NOx) in discharge plasma. Nitrogen oxides (NOx) play an important role in the process of ozone generation in air discharge, where the catalytic cycle for ozone destruction takes place. So the nitrogen influencing factor should be considered. Formula is derived for predicting the characteristics of the ozone generation, within the corona inception voltage to the gap breakdown voltage. The predicted results are shown to be in good agreement with experimental findings.

In this paper, the effects of organic acid radicals on degradation of Orange II in UV-Fenton system with hydroxyl-Fe-pillared bentonite as catalyst were studied in detail. The results showed that the rate constants of UV-Fenton reaction will decrease when the system contains sodium citrate or sodium malonate. While the rate of Orange II degradation in UV-Fenton system could increase up to 33.3% and 41.7% when EDTA and sodium oxalate were present, respectively. As the additional TOC of EDTA is higher than sodium oxalate, adding sodium oxalate is a more promising enhanced method for Orange II degradation in UV-Fenton system. The rate of Orange II degradation could increase 25%, 42% and 175% when the concentrations of additional sodium oxalate increased up to 0.1 mM, 0.2 mM and 0.4 mM, respectively.

ZnO thin films were deposited on polyimide foil substrates using cathodic vacuum arc deposition technique. X-ray diffraction was used to investigate the influence of bias voltage on the structure of ZnO thin films. The results show that all the samples have (002) preferred orientation. The internal stress of the films is compressive stress which increases with the bias voltage. Fragmentation test shows that the intrinsic interfacial shear strength of ZnO thin film without bias voltage is slightly lower than the shear yield strength of polyimide substrate; the intrinsic interfacial shear strength of ZnO thin film increases with the bias voltage from -50V to -200V, which indicates that bias voltage is beneficial to the enhancement of the adhesion between ZnO films and polyimide substrates. Further increase of the bias voltage to -300V leads to surface damage of the polyimide substrates.
