乙型脑炎灭活疫苗Vero细胞适应毒种的研究

将乙脑P3株鼠脑毒种在Vero细胞中适应性传代，当传至10代时，毒种的CPE和感染性虽无明显变化，但其免疫原性却明显减弱，因此，用在Vero细胞中传递1至2代的几株建立毒种库（P3V1和P3V2），其涵度分别为7．71和78210gpfu／ml。在毒种中加入以山梨醇为主要成分的稳定剂后，4～S℃保存30天，－30℃1年，－60℃2年，滴度降低约0．51ogpfu／ml，在生产中使用效果良好。     

Rapid and large‐scale separation of magnetic nanoparticles by low‐field permanent magnet with gas assistance

Bubbles can be used to greatly improve the speed of magnetic separation (MS) and overcome the limitation of magnetic force on the capture distance, making low‐field MS highly efficient and easily scalable. This novel method leads to the development of a medium‐free continuous gas‐assisted magnetic separator on small pilot scale using low‐field permanent magnet. This separator is demonstrated highly efficient for recovery of proteins‐loaded magnetic nanoparticles from large volume biosuspension. © 2014 American Institute of Chemical Engineers AIChE J, 60: 3101–3106, 2014     

Inorganic microencapsulated core/shell structure of Al–Si alloy micro-particles with silane coupling agent

Al–Si eutectic alloy is a kind of ideal high temperature phase change materials (PCMs) because of its high latent heat and good heat transfer performance. However, it is difficult for Al–Si alloy to be safely applied because of its causticity and incompatibility. In this paper, an inorganic Al–Si/Al₂O₃ micro-particles core/shell structure was prepared by the sol–gel process with the modification of silane coupling agent. The direct evidence for the forming of the dense and stable α-Al₂O₃ shell layer, whose thickness is about 3–5 μm, is presented by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). In terms of the analyses of Fourier transform infrared (FT-IR) and thermogravimetry (TG), it is apparent that the silane coupling agent is successfully grafted on the surface of Al–Si alloy micro-particles, which promotes the condensation between boehmite sols and silanol groups. The latent heat of the encapsulated Al–Si alloy was 307.21 kJ/kg and decreased during the process of microencapsulation. The reasons for the reduction of the latent heat are the excess alumina sols and the depletion of Al–Si alloy.     

The flame‐retardant properties and mechanisms of poly(ethylene terephthalate)/hexakis (para‐allyloxyphenoxy) cyclotriphosphazene systems

Para‐allyl ether phenol derivative of cyclophosphazene (PACP) was prepared and used as a filler to modify the flame‐retardant properties of poly(ethylene terephthalate) (PET) by melting‐blending. The mechanism of flame‐retardant was discussed and the influences of flame‐retardant contents to the mechanical properties were studied. The results revealed that the incorporation of only 5 phpp PACP (0.37 wt % phosphorus containing) into PET matrix can distinctly increase the flame retardancy of PET/PACP composition, and it has a little effect on the mechanical properties of PET. The high flame‐retardant performance of PET/PACP composite was attributed to the combination of condensed‐phase flame retardant and gas‐phase flame retardant. © 2015 Wiley Periodicals, Inc. J. Appl.

复合菌处理抗生素废水的初步研究

抗生素废水由于有机物含量高、含有较多残留的抗生素,常规的处理方法很难达到处理要求.从处理抗生素废水的活性污泥中分别分离出3株光合细菌、酵母菌、放线菌,通过比较处理效果,确定后续试验的菌种.最后,通过菌种单因素试验、菌种复配试验、复合菌种配比正交试验,确定了复合菌种的最佳配比:光合细菌、酵母菌和放线菌投加量分别为10、6、2g/L.此时COD去除率可以达到60.48％.
