Antimony is more than an emerging pollutant in water but a scare *** this study,we report an adsorbent with the record capacity so far from the balanced view of Sb(Ⅲ) and Sb(Ⅴ).The composite adsorbent was fabricated by encapsulating hollow Fe_(3)O_(4)nanosphere with the EDTA grafted chitosan,and it has superhigh adsorption capacity of for 657.1 mg/g for Sb(Ⅲ) and 467.3 mg/g for Sb(Ⅴ),*** mechanism study reveals that the adsorption of Sb initializes from the Fe_(3)O_(4),propagates along the chitosan with hydrogen bond,and terminates at the inner sphere complex with the EDTA moiety in the *** view of the ultra-high adsorption capacity of the adsorbent,the recovered adsorbent that contains abundant (>36.4%) highly dispersed antimony nanoparticles (600-FCSE-Sb) is applied to Li-ion battery anode after *** article provides a new idea for connecting water treatment and electric energy storage.

为改善车用百叶窗翅片换热器空气侧换热性能,提出一种带涡流发生器百叶窗翅片结构。采用数值模拟方法计算出新型翅片与传统翅片在不同雷诺数(Re)下的传热因子j,阻力因子f和综合性能因子JF,分析了两种翅片的流动和换热特性。结果表明:在Re为100~500时,与传统翅片相比,带涡流发生器翅片的传热因子j增加了2.9%~4.0%,阻力因子f上升了1.6%~2.0%,综合因子JF提高了2.2%~3.4%,因此带涡流发生器换热器换热性能优于传统百叶窗换热器。

In order to establish a rapid RT-PCR assay for detection of porcine epidemic diarrhea virus（PEDV）,a pair of special primers was designed based on S gene sequence of PEDV published in Gen *** optimization of the reaction system,a rapid RT-PCR method was *** showed that a fragment of 826 bp was successfully amplified only from the variant PEDV by RT-PCR,while the expected target fragment could not be amplified from TGEV,porcine rotavirus,porcine kobuvirus,PRRSV,PRV,CSFV,*** test of RT-PCR indicated that only 11.3 pg nuclear acids could be detected accurately and rapidly.A total of 123 samples collected from different farms in Guangxi Province were detected by the established RT-PCR,the positive rate of PEDV was 67.5%,and the positive rate of new PEDV was 86.7%（72/83）.Therefore,the RT-PCR could be used as an effective tool for differentiating diagnosis of the highly pathogenic PEDV in epidemiological investigations.

In order to develop swine hepatitis E （HE） genetically engineering vaccines, specific primers of genes LB1, LB2, LB3 of swine hepatitis E virus were designed and used for amplification, DNA amplieons generated by PCR assays were directly cloned into T-A plasmid and expressed using pEASY-M1 expression vector. Three recombinant eukaryotic expression plasmids of pEASY-LB1, pEASY-LB2 and pEASY-LB3 were constructed. The eukaryotic expression plasmids of pEASY-LB1, pEASY-LB2, and pEASY-LB3 were transfected into 293T cells, and three target genes were detected by real-time fluorescent quantitative RT-PCR. The results confirmed that three eukaryotic expression plasmids were transfected into 293Teells and target protein was expressed. Analysis by SDS-PAGE electrophoresis and Western-blot indicated that three target proteins were expressed in 293T cells transfected with eukaryotic expression plasmids of pEASY-LB1, pEASY-LB2 and pEASY-LB3. Antigenicity studies indicated good HEV responses. Therefore, three recombinant DNAs of HEV ORF2 nucleic acid vaccine candidates were ob- tained, which might lay the foundation for further studies in the future.
