A wood-based Ni-P coating electromagnetic shielding material was prepared in an ytterbium oxide-added electroless plating bath. The kinetic model was established and confirmed to be in accord with the experiment and can be used to predict the deposition rate within a certain range. The experimental results showed that the Ni-P coating prepared with the addition of Yb2O3 were smoother, denser and brighter than that prepared without addition of Yb2O3. The deposition rate and electromagnetic shielding effectiveness of the former were 2.662mol×10-4/(cm2h) and 56.48 dB which is about 13% and 9% higher than those of the latter under the same bath compositions and operation conditions.

Alkyd resin dispersions are used in the paint industry as the basis for the new generation of environmentally friendly gloss paints. This research based on two-component seed oil soybean oil and castor oil to synthesis high-efficiency modified alkyd resin. The experimental conditions are the mass ratio of soybean oil with castor oil is 2:1, 55% degree of oil, Ni(OH)2 as the catalyst and 210°C~220°C for alcohol solution reaction, 220°C for esterification under the protection of nitrogen. The experimental results show that the product non-drying days are more than 30 days, acid value is 6.6, the migration is 1.2%, adhesion is one level, flexibility is 0.5, chroma value is 8.

An effective emulsion liquid membrane system with P507 as carrier, Span-80 as surfactant and H2SO4 as internal aqueous phase was established to treat Ni(Ⅱ)-containing wastewater. The effects of volume fraction of Span-80 in the oil phase(φ(Span-80)), emulsifying stirring speed(ν1), separation stirring speed(ν2), volume fraction of P507(φ(P507)), volume ratio of oil phase to internal phase(Roi), milk phase to water phase(Rew) and concentration of H2SO4 in internal aqueous phase on Ni(Ⅱ) migrating rate have been investigated in the course of migrating of nickel ions in the system. The optimal operation conditions were determined to be: φ(Span-80)=8.5%,ν1 =3600 r·min-1,ν2 =320 r·min-1, φ(P507)=6.5%, Roi =1:1, Rew =2:5 and c（H2SO4）=1.6 mol·L-1 ,under which the migrating rate of nickel ions reached above 97%.

Reed Pulp was Raw Material that Pretreated by Four Methods {ultrasonic, Microwave, N, N-Dimethyl Acetamide (DMAc) and Tetrahydrofuran (THF)}. Reed Microcrystalline Cellulose (MCC) was Prepared by the Dilute Hydrochloric Acid Hydrolysis from Pretreated Reed Pulp. the Influences of Pretreatment Methods on Crystalline Type, Crystallinity and Crystallite Size of MCC were Investigated by X-Ray Diffraction (XRD). the Results Showed that the Crystallinity of MCC with Four Pretreatment Methods was 68.45%, 62.28%, 63.21% and 69.56%, Respectively. the Average Crystallite Size of MCC Prepared by Hydrolysis after Pretreated by Dmac was the Largest. whereas, the Crystal Type of MCC was Not Changed, it was still the Cellulose Type I. Comprehensive Analysis Indicated that the Effects of MCC Prepared by Hydrolysis after Pretreated by Ultrasonic were the Best.

In this study, we apply the Sequential Panel Selection Method (SPSM), proposed by Chortareas and Kapetanios (Journal of Banking and Finance 33:390-404, 2009), to investigate and assess the non-stationary properties of the real interest rate parity (RIRP) for fourteen Latin American countries. Utilizing the SPSM, we can classify the entire panel into a group of stationary series and a group of non-stationary series. We clearly identify how many and which series in the panel are stationary processes and provide robust evidence that clearly indicate RIRP holds true for ten countries. Our findings note that these countries' real interest rate convergence is a mean reversion toward RIRP equilibrium values in a non-linear way. Our results have important policy implications for these Latin American countries under study.
