| 1 | Dynamic changes of microbial community diversity in a photohydrogen producing reactor monitored by PCR-DGGE显示文摘A PCR-DGGE (denaturing gradient gel electrophoresis of polymerase chain reaction) protocol was used for monitoring the dynamic changes in the microbial population during photohydrogen production. Total DNA was extracted directly from the mixed bacterial community in the reactor and subjected to PCR with V3-16S rDNA and pufM gene primers, and the amplifications were then analyzed by DGGE. The DGGE patterns demonstrated the dynamics of community structure and the shift of microbial diversity, which corresponded to different running periods of the reactor. The optimal hydrogen producing community formed on day 10. Using DGGE analysis with the pufM gene fragments was superior to V3-16S rDNA region genes for detecting the dynamic variations of the photosynthetic bacteria population during hydrogen production. The comparative sequence analysis of excised DGGE bands showed the relationship between specific population structures and system performance. Rhodopseudomonas palustris was presumed as one of the dominant community members for hydrogen production in the reactor. The PCR-DGGE protocol was proven to be a good tool for monitoring the photohydrogen production in real time and offered the available information to improve the photohydrogen producing system. | Yanling YING Jun CHENG | 2008 | Journal of Environmental Sciences2008，20，9： | 11 |
| 2 | Surface modification of acrylate intraocular lenses with dielectric barrier discharge plasma at atmospheric pressure显示文摘Surface modification with dielectric barrier discharge(DBD) plasma was carried out at atmospheric pressure(argon as the discharge gas) to improve the biocompatibility of hydrophobic acrylate intraocular lens(IOL).Changes of the plasma-treated IOL surface in chemical composition,morphology and hydrophilicity were comprehensively evaluated by X-ray photoelectron spectroscopy(XPS),field emission scanning electron microscopy(FESEM),atomic force microscopy(AFM) and water contact angle(WCA) measurements.The surface biocompatibility of the untreated and plasma-treated IOLs was compared with the adhesion behavior of platelets,macrophages and lens epithelial cells(LECs) in vitro.After DBD plasma treatment,the hydrophilicity of the IOL surface was obviously improved.The changes in WCA with treatment extension may be attributed to both the introduction of oxygen or/and nitrogen-containing polar groups and the increase of surface roughness induced by plasma etching effect.The existence of low molecular weight oxidized material(LMWOM) was proved on the plasma-treated IOL which was caused by the chain scission effect of the plasma treatment.The plasma-treated IOLs resisted the adhesion of platelets and macrophages significantly.The LECs spreading and proliferation were postponed on the IOLs plasma-treated for more than 180 s,with a well maintained epithelial phenotype of LECs.The IOL biocompatibility was improved after the DBD plasma treatment.We speculate that slighter foreign-body reaction and later incidence of anterior capsule opacification(ACO) may be expected after implantation of the argon DBD plasma-treated IOL. | WANG Yao LIU ZhenMei XU ZhiKang YAO Ke | 2009 | Science China Chemistry2009，52，8： | 3 |
| 3 | Preparation of Ti-Mo getters by injection molding显示文摘Ti-Mo getters have been fabricated via metal injection molding (MIM) using three kinds of Ti powders with different mean particle sizes of 46 μm,35 μm and 26 μm,respectively. The surface morphology,porosity,and hydrogen sorption properties of Ti-Mo getters formed by MIM using paraffin wax as a principal binder constituent were examined. It has been proven that the powder injection molding is a viable forming technique for porous Ti-Mo getters. The particle size of Ti powders and the powder loading influence the porosity of getters,and this affects the sorption capacity of Ti-Mo getters. Ti-Mo getters produced with the Ti powders possessing a mean particle size of 35 μm using a powder loading of 40 vol.% have a high porosity,resulting in a good sorption capacity. | Zhao, Zhenmei Wei, Xiuying Xiong, Yuhua Mao, Changhui | 2009 | Rare Metals2009，28，2： | 2 |
| 4 | On the Negative Effects of Trend Noise and Its Applications in Side-Channel Cryptanalysis显示文摘Most existing noise reduction methods in side-channel cryptanalysis treat all noises as a whole, instead of identifying and dealing with each of them individually. Motivated by this, this paper investigates the feasibility and implications of identifying trend noise from any other noises in side-channel acquisitions and then dealing with it accordingly. We discuss the effectiveness of applying least square method to remove inherent trend noise in side-channel leakages, and also clarify the limited capability of existing noise reduction methods in dealing with trend noise. We performed a series of correlation power analysis attacks against real power traces publicly available in DPA contest v2 from an unprotected FPGA implementation of Advanced encryption standard(AES) encryption.The experimental results firmly confirmed the soundness and validity of our analysis and observations. | CAO Yuchen ZHOU Yongbin YU Zhenmei | 2014 | Chinese Journal of Electronics2014，23，2： | 2 |
| 5 | Soil Organic Carbon Stocks of Citrus Orchards in Yongchun County Fujian Province China显示文摘Studies related to the quantitation and distribution of soil organic carbon(C) under different land use types can help to fill the knowledge gaps regarding estimation of the amount of C stored in soils at a global scale. Orchards are an important land use type in southern China; the total area(1.15 × 10~7 ha) of orchards in China comprises approximately 20.5% of the area of all orchards worldwide. We assessed soil organic C stocks(SOCS) in citrus orchards in Yongchun County(consisting of 22 towns), Fujian Province,China in 1982 and 2010. The southeastern part of the county, an area featuring extensive citrus farming with a gently sloping landscape and low rates of water erosion, had the highest SOCS. In contrast, the lowest SCOS was observed in the northern part of the county,where steep hills with severe erosion problems are common and citrus orchards are sparsely distributed. From 1982 to 2010, the mean SOCS in citrus orchards increased from 22.1 to 41.7 Mg ha^(-1), which indicated that current management practices such as fertilization,irrigation, and cultivation enhanced soil C stocks. Further in-depth studies on the effects of these practices on C sequestration would be worthwhile and surveys of SOCS throughout Fujian Province are needed, to support efforts to mitigate global C emission. | WANG Yixiang WENG Boqi TIAN Na ZHONG Zhenmei WANG Mingkuang | 2017 | Pedosphere2017，27，5： | 1 |
