篇1：Fluorapatite: An Effective Solid Bas

Fluorapatite: An Effective Solid Base Catalyst for Michael Addition of Indole/pyrrole to Nitroalkenes under Solventless

Solid base fluorapatite was found to catalyze the Michael addition of indole/pyrrole to nitroalkenes efficiently under solventless condition, affording the products in good to excellent yields. The Michael addition occurred at the 3-position of indole exclusively with an exception of 3-methylindole. The synthetic fluorapatite could be recovered and reused easily without obvious loss in activity.

篇2：Validation of Flight Control Law Bas

Validation of Flight Control Law Based on LFT and Structured Singular Value

The main goal of flight clearance is to use the structured singular value (μ) analysis of the flight control system when some parameters in the system vary in a certain range. As theμ-analysis can only be done on a linear fractional transformation (LFT) model, the first step of flight clearance is to generate the LFT model of the flight control system. In this paper, based on the introduction of basic theory of LFT and μ-analysis, an X-fighter is chosen as an example to utilize the proposed methods. In order to realize the flight clearance process automatically, a novel software package based on MATLAB programming language is developed. The results of simulation experiments validate the feasibility and effectiveness of the novel methods proposed in this paper.

篇4：DNA purification and gene typing:Bas

DNA purification and gene typing:Based on multifunctional nanobeads

In this report, a universal protocol for extracting genomic DNA from whole blood, saliva, and bacterial culture by using magnetic nanobeads as solid-phase absorbents was presented. The enrichment of target cells and adsorption of DNA have been functionally integrated onto the surfaces of the carboxyl-modified magnetic nano-beads, and the DNA segments bound on the surface of the beads can be directly used as PCR templates to amplify a target gene. The PCR products were applied to an oligonucleotide array to perform gene typing. The protocol proves to be simple, rapid, biologically and chemically nonhazardous, and promising for the microfabrication of DNA preparation chip.

篇5：Cf/BAS复合材料的氧化行为研究

Cf/BAS复合材料的氧化行为研究

采用热压工艺成功的合成了碳纤维/钡长石(Cf/BAS)复合材料,研究了这种复合材料的氧化行为.结果表明,Cf/BAS复合材料的氧化失重与基体微裂纹有关.基体中的微裂纹提供了氧化性气体的扩散通道,从而导致高温下碳纤维的严重氧化.随着时间的增加,氧化性气体沿内部碳纤维的扩散路径逐渐增加,残留碳纤维的'氧化速度逐渐降低.Cf/BAS在燃气中氧化后力学性能降低的幅度比在空气中降低小一些,这是由于燃气中的氧分压较低,纤维的氧化程度不如在空气严重.
