Study on Toxic Effect of Nanomaterials on Organisms

Zhongguo anquan kexue xuebao (2010)

Haiqun Chen Wang Kai-quan

The calculation based on the first proliferation formula of Einstein and the settlement formula semi-quantitatively and quantitatively indicates that the nano-particles' settling velocity is about one thousandth of micron particles'. This feature makes nano-particle more easily suspend in the atmosphere and solution and be absorbed by organisms through respiratory and circulatory system. Meanwhile, the calculation based on the interaction potential energy formula caused by Vander Waals force semi-quantitatively indicates that nano-particle is easier than micron particle to be adsorbed, aggregated and collected into the body from the food chain through transformation in the atmosphere or migration in water and soil. Therefore, nanoparticle has more serious toxicity and worse effect on organisms than micron particles. Finally, according to the research on the toxicity of nanomaterials, new direction to the virtuous development of nano-technology is proposed.

Strategy for Rapid Recovery of Simultaneous Sulfide and Nitrite Removal under High Substrate Inhibition

Research Square (Research Square) (2021)

Wang Kai-quan Qaisar Mahmood Bilong Chen Siyi Liu Yuanyuan Wu

Abstract The paper deals with the strategy for a quick recovery of reactor treating sulfide and nitrite simultaneously under inhibition caused by high substrate concentration. For influent sulfide concentration of 360 mg S/L, respective sulfide and nitrite removal percentages dropped to 74.19% and 14.33% due to inhibition caused by high sulfide and nitrite concentrations. It was found that reduction in the influent substrate concentration (300 mg S/L) could not revive the nitrite removal performance in 4 days’ operation, which still showed a declining tendency from 47.16–18.52%. Regulating the influent pH around 6.70 ± 0.10, it only took 4 days to recover the performance for 300 mg S/L. Furthermore, at influent sulfide concentration increased to 360 mg S/L, respective sulfide and nitrite removal percentages were 99.76 ± 0.27% and 100%. The strategy of regulating influent pH could recover the process performance in a short term, which would provide great convenience for subsequent process research.

Melt flow properties, mechanical properties, thermal properties and morphology of polycarbonate/highly branched polystyrene blends

Polymer International (2006)

LI Ai-ying Chang Jie-yun Wang Kai-quan Lude Lu Xujie Yang

Abstract A highly branched polystyrene (HBPS) was synthesized via the copolymerization of 4‐(chloromethyl) styrene with styrene using the self‐condensing atom transfer radical polymerization method. The addition of HBPS as a melt modifier for polycarbonate (PC) was attempted. Melt flow properties, mechanical properties, thermal properties and morphology of the blends were studied. The results showed that a significant drop in the blend viscosity occurs immediately on addition of HBPS. Impact strength, tensile strength and glass transition temperature ( T g ) of all the blends have not been significantly reduced compared with those of pure PC. The TGA analyses showed that an initial weight loss temperature of all the blends is above 458 °C and slightly low compared with that of pure PC, but all the blends still have excellent thermal stability. Morphological studies using SEM showed that a two‐phase morphology is characteristic of all the blends, with more or less spherical droplets of the minor HBPS phase dispersed in the continuous PC phase.

Risk Information Management System of City Gas Line Based on GIS

Ning Zhou Shihui Xu Xuanya Liu Wang Kai-quan Huijun Zhao

The pipe network has throughout each corner and entrance thousands of families with the constant development and expansion of gas pipeline in our country; it also has provided our life with more convenience. However, since geological conditions and surrounding environment of gas pipeline are very complex, and gas transportation in pipeline is flammable, explosive, toxic and pernicious; once leakage happens in pipeline, it is apt to cause combustion, explosion accident, casualties and enormous property losses. Therefore, pipeline security has gradually become a critical concern of the country and the whole society. Taking geographic information system (GIS) as a platform, a set of city natural gas pipe network risk management information system was developed using the MapX C/S structure pattern in this study, which can realize real time inquiry of pipeline basic information and security evaluation. It has also set up a variety of emergency response measures and rescue proposals when an accident takes place. It offers technical support for incident succor and emergency response management. It also can forecast a variety of consequences such as flame, blast and leakage accident through invoke background program; the coverage of incident can be shown in graphs. It can provide optimized rescue route and personnel evacuation path, supporting technically for rescue decision making.

Risk Characteristics of Urban Natural Gas Pipeline and Improvement of the Kent Method

Zhongguo anquan kexue xuebao (2008)

Wang Kai-quan LU Ze

The Kent Grading method,which was suitable for pipeline analysis in cities,was firstly improved in the items of grading and factor weights according to urban pipeline characteristics.Then,it was applied to the risk assessment of a 21-kilometer-long high-pressure natural gas pipeline,and 8 pipe sections with relatively high risks were obtained.The analysis result can be taken as theoretical basis for safety management staff to reasonably distribute maintenance resources.This engineering illustration shows that the improved Kent method is feasible,and is an effective tool to assess the risk of urban high-pressure gas pipelines.
