Cell membranes are bacteria’s first barrier against outside invasions. In this research, permeability of cell membranes will be changed so as to improve toxicity detection sensitivity of vibrio qinghaiensis (Q67). During the cultivation process of Q67, the Ethylene Diamine Tetraacetic Acid (EDTA-Na2) will be added and the hydrophobic fluorescent probe N-Phenyl-1-Naphthylamine (NPN) will be used to test changes of Q67 cell permeability. In addition, the low temperature centrifuge method will be used to eliminate interferences of residual EDTA of the nutrient medium to the acute toxicity test. The microporous plate method of biological toxicity test will be used to test the acute toxicity of K2Cr2Q7, the phenol and the desmetryn on Q67 before and after the permeability is modified. The results show that: during the cultivation process of Q67, if 2.0 mmol/L EDTA-Na2 is added, 40.2% of its absorbability to NPN can be improved. What is more, normal growth and bioluminescent property of Q67 will not be affected. EC50 of the K2Cr2Q7, the phenol and the desmetryn to the modified Q67 is 4.39 mg/L, 128.75 mg/L and 145.89 mg/L respectively. Compared with those before the modification, their EC50 reduces 45.70%, 39.77% and 38.61% respectively.

Published: September 2014

Energy harvesters of PVDF can be used to power small electrical loads or wireless sensor systems. Simple technologies are sufficient for the fabrication of these harvesting modules. Critical process step is the polarization of the piezoelectric material. Main piezoelectric parameters depend strongly on the polarization material. Particularly, the electric field strength and the polarization temperature influence the remanent polarization of PVDF. Dielectric breakdowns of the film at higher temperatures prevent a sufficient polarization. At least, all modules were polarized at a field strength of 100 – 120 MV/m and a temperature of 90°C.Modules with dimensions of 165mm x 95mm x 1.5mm were used to power a commercial available “development kit for Energy Harvesting Wireless systems” (EnOcean ‘EDK 300’). The modules possess of 20 layers of PVDF. Each module was connected via a standard four diode full rectifier bridge with the development kit EDK 300. Positioned underneath a parquet floor (thickness=10mm), the modules converted mechanical energy of footsteps into electricity. Goal of these investigations were to find out configurations suited to generate a sufficient energy level to supply the operation of the EDK 300. Two capacitors in the development kit are used to start the operation of the kit (C1=470μF) and to store converted energy (C2=0.25F). Already a few steps onto one module were sufficient to charge C1 and to start the operation of the EDK 300. Following steps (>100) produced energy which was stored in C2.

Nitrification-denitrification biological nitrogen removal process has become the hotspot for the wastewater. During carbon/nitrogen (C/N) ratio was 1.16, 2.25, 4.07 and 6.20, the change of denitrification efficiency and the impact on the partial nitrification/denitrification was investigated. The results showed that removal rate of ammonia nitrogen was maintained in the high level, and was stable above 98% after C/N ratio higher than 1.16. With C/N ratio increased, the removal rate of chemical oxygen demand was increased about 20%, total nitrogen was increased from 54.9% to 84.6%. Simultaneously, after C/N ratio was higher than 4.07, the concentration of effluent TN was below 15 mg/L. Nitrite accumulation rate was maintained above 95%, the effect on partial nitrification was good, and the concentration of effluent nitrate was nearly 0, the best ratio of the C/N ratio was 4.07.

Published: September 2014

Water scarcity is a critical issue in most regions of China; however, river basin groundwater monitoring is extremely limited.This study evaluates the ability of the GRACE satellites and Global Land Data Assimilation System(GLDAS) to monitor groundwater storage in the Yellow River Basin and Yangtze River Basin, China, which is subjected to intense irrigation, production and living. The simulated terrestrial water storage change data which was calculateed by Global Land Data Assimilate System was used to compare the accuracy of GRACE data. Results show that both two datas show significant seasonal cycle in the Yangtze River and Yellow River (except frozen soil), the correlation is 0.89 and 0.84(p<0.05).Two methods have some differences on grid scales, the results which was retrieved by GRACE satellites have better continuity than simulated by GLDAS. GRACE inversion results reflect deeper water storge change in soil, and GLDAS simply reflect surface soil moisture.

Li2O-Al2O3-SiO2 glass-ceramics doped with Nd2O3 were prepared by the melting method. The effects of Nd2O3 on the crystallization behavior of Li2O-Al2O3-SiO2 glass-ceramics were studied by DTA, XRD and SEM. With the increase of Nd2O3 content, the glass crystallization temperature arised. The SEM result indicates that the main crystal phase of Li2O-Al2O3-SiO2 glass-ceramics doped with Nd2O3 is β-quartz solid solution, for without doping Nd2O3 it is β-spodumene solid solution. These results shows that the crystallization temperature increases significantly by doping Nd2O3, and phase transition from β-quartz to β-spodumene is suppressed. The grain size increases with the increase of Nd2O3 content.
