Authors: Luo Lan , Xiong Zhi Hua , Zhou Nai Gen
Published: February 2012

Combinatorial material synthesis and high throughput evaluation technique have been developed to accelerate material discovering and optimizing. The thin-film combinatorial material library (or material chip), similar to the integrated circuit chip, contains thousands even millions of different compounds, and could be used to screen for the desirable physical or chemical properties. In our work, the rare earth activated gadolinium aluminate perovskite phosphor(GAP:RE1x, RE2y, RE ion vary among Eu3+, Ce3+,4+, Pr3+,4+) combinatorial library is made by ion beam sputtering sequence deposition and two-step thermal processing. The GAP:RE1x, RE2y, combinatorial library indentify the “lead” red luminescent compound as GAP:Eu0.11from the 16 candidates with the help of the photoluminescent (PL) photograph under UV light. Three another compounds have been also picked out as GAP:Eu0.1, GAP:Eu0.1,Ce0.01, GAP:Eu0.1,Pr0.01. Other than the information on “lead” compounds, the discrete combinatorial library provides a quick way to map out the relationships between activators and host, sensitizers and activators： 1) Eu3+is a better red luminescent activator than Ce3+,4+, Pr3+,4+in GAP polycrystalline; 2)Neither Ce3+,4+nor Pr3+,4+is a proper sensitizer for Eu3+. The excitation and emission spectral indicate the resonance energy transfer between the activator and sensitizer must have happened, which leads to Ce3+,4+or Pr3+,4+codoping decrease Eu3+red luminescence intensity. The candidates in powder form are prepared by nitric-citric method for more detailed characterization. All the screening results, obtained from the combinational library, are coherent with the powder phosphor experiments.

Published: February 2012

Abstract: With the purpose to improve the mechanical properties and cut costs of chitosan films, a series of gelatin-chitosan films were prepared. The effect of gelatin content on the mechanical properites of films was studied. FT-IR spectrum and X-ray diffraction analysis showed good compatibility between gelatin and chitosan. The composite films exhibited a higher TS(tensile strengths) and ES(elongation at break) compared with chitosan film, especially when the content of gelatin in blends was 30%. The TS and ES revealed that the interaction between chitosan and gelatin was the strongest when the content of gelatin in blends was 30%. The results obtained from percent water absorption indicated these two biopolymers were high hydrophilicity polymer. The water solubility of composite films was higher than chitosan films. The results suggest that the interactions between gelatin and chitosan was good for the mechanical properties of composite films.

Particle filtering has important applications in location, tracking and other fields. It indicates probability using particle set and can be used in any space-state model. Its core idea is to extract a random state from the posterior probability express the distribution. In general, particle filtering is a process which uses a set of stochastic sample propagating in space-state to approximate probability density function and to replace integral operation with mean value of a sample to obtain minimum state variance distribution. It solves the restriction that nonlinear filtering should match Gaussian distribution, expresses a wider range of distribution than Gaussian distribution and has a strong ability to model the nonlinear characteristic of variance parameter. This paper introduces the application of particle filtering in visual tracking. Finally, it puts forward some improved algorithms to revise the inherent deficiencies existing in particle filtering.

In order to quantitatively evaluate the clean degree of coal resources, the evaluation model and the evaluation system are constructed based on multi-factor and multi-hierarchy evaluation index. Two first-tier indexes, five second-tier indexes and sixteen third-tier indexes are adopted according to the content of harmful elements in coal and their toxicity to establish the evaluation index system. The adopted indexes are quantized using statistical mathematical method, and their weights are obtained utilizing the AHP method. Applying the fuzzy mathematics theory, the multi-hierarchy fuzzy comprehensive evaluation model is established, which is a good basement for further conducting the clean degree evaluation of coal resources.

Published: February 2012

The effects of H2O2 addition to degradation efficiencies of TiO2 and the mixture of TiO2 and HZSM-5 were investigated. When H2O2 concentration increased from 2 mmol/l to 8 mmol/l, methyl orange decoloration rates increased from 41% up to 90%. TiO2 concentration was 100 mg/l and decoloration rates varied with increasing H2O2 concentration. Decoloration of methyl orange increased from 45.3% to 90.3% when H2O2 concentration increased from 2 mmol/l to 8 mmol/l. Total decoloration of the dye mainly came from oxidation of methyl orange by either oxidation of H2O2 and photocatalytic oxidation process. There was a maximum H2O2 concentration in methyl orange degradation when using mixture of TiO2 and HZSM-5.
