| 1 | Efficient production of ethyl levulinate from cassava over Al2(SO4)3 catalyst in ethanol–water system显示文摘One-pot achievement of ethyl levulinate from cassava was conducted in ethanol-water system over several simple sulfate salt catalysts.Al_2(SO_4)_3 catalyst had the best performance in synthesizing ethyl levulinate comparing with those of a series of sulfate salts.The highest yields of ethyl levulinate was up to39.27%as well as 7.78%levulinate acid when cassava was catalyzed in ethanol medium by adding 10 wt%water.^(13)C and ~1H NMR spectroscopic investigations confirmed that isomerization of glucose to fructose over Al_2(SO_4)_3 catalyst is an important step in producing ethyl levulinate and levulinate acid.Due to aggregations of Al^(3+) under hydrothermal conditions,tiny amount of Al^(3+) were detected in filtrate at the percentage of 0.32%even if in absolute water.Bronsted and Lewis acids could improve the yield of ethyl levulinate and levulinate acid by synergistic effect.All results suggested that A1_2(SO_4)_3 was a simple and efficient catalyst for ethyl levulinate and levulinate acid production. | Jin Tan Qiying Liu Lungang Chen Tiejun Wang Longlong Ma Guanyi Chen | 2017 | Journal of Energy Chemistry2017，26，1： | 11 |
| 2 | Monitoring of atmospheric radionuclides from the Fukushima nuclear accident and assessing their impact on Xi'an, China显示文摘Aerosol radionuclides (131I, 134Cs, 137Cs) and gaseous radioactive xenon (133Xe) were monitored at Xi'an, China following the accident at the Fukushima nuclear power plant in March 2011. The additional annual effective dose attributable to the Fukushima emissions was much lower than the public annual effective dose from natural radiation, according to Chinese national standards. The monitoring results were compared with data from other countries as well as with the radionuclide concentrations observed in Xi'an after the Chernobyl nuclear accident in 1986. Possible transport pathways of the released radionuclides from Fukushima to Xi'an were investigated. The occurrence of an anticyclone in the Pacific Ocean region and the extended period over which the radionuclides were released made the determination transport pathways complex, but divergence in the plume and easterly flow evidently brought the initial suite of radionuclides to Xi'an. | LIU LongBo WU Shan CAO JunJi XIE Feng SHI QuanLin ZHANG ChangYun TANG HanBing HE XiaoBin ZHANG Rong CHEN LiYun WEI GuanYi ZHANG ZhiHong ZHANG JiaMei DANG HaiJun | 2013 | Chinese Science Bulletin2013，58，13： | 4 |
| 3 | Spillover effect of environmental investment: evidence from panel data at provincial level in China显示文摘这份报纸把污染密度看作环境投资的功能。越高环境投资,越多降低污染密度。更低污染密度是更高的生产技术变得。这被称为溢出效果。我们从 2005 ~ 2009 在省的水平收集了中国的面板数据,并且测试了环境投资的溢出效果。这份报纸发现环境投资断然影响了生产技术。在政府开销和溢出效果之间有一种重要积极关系。 | Qunhui LIN Guanyi CHEN Wencui DU Haipeng NIU | 2012 | Frontiers of Environmental Science & Engineering2012，6，3： | 3 |

| 5 | Effect of acupuncture treatment on smoking cessation in smokers from Hong Kong显示文摘OBJECTIVE: To analyze the characteristics of smokers treated with acupuncture for smoking cessation in Hong Kong.METHODS: A total of 2051 subjects were recruited in a clinical pilot research project 'acupuncture for smoking cessation', which was conducted jointly by Institute of Acupuncture and Moxibustion, China Academy of Chinese Medical Sciences and Hong Kong Pok Oi Hospital from January of 2011 to December of 2013. The characteristics of study subjects, including baseline information, smoking background, intention to quit and influencing factors were analyzed.RESULTS: The majority of subjects treated with acupuncture for smoking cessation in Hong Kong was male(66.7%), but the proportion of female smokers in this study(33.3%) was higher than that of female smokers in Hong Kong population(13.8%, P <0.05). Subjects were at the mean age of 43.83 years old, of which the percentage of females aged 31-40 years was the highest(38.8%, P < 0.05). The mean duration of smoking was 25.49 years. The number of cigarettes smoked per day was 17.57 cigarettes.Fagerstrom Test for Nicotine Dependence(FTND)was 5.29 points. Most of the subjects had attempted quitting smoking(81.42%). The confidence index(7.44 points) and the readiness to quit smoking(8.13 points) were high. Subjects quitting smoking were mostly due to health cause(81.91%). The majority of subjects were at the level of middle school(61.63%). The higher the educational level was, the lower the tobacco dependence was and the higher the confidence in successfully quitting smoking was. 50.27% of subjects chose acupuncture for smoking cessation mainly through friends, television and network publicity. Subjects who had received acupuncture had the highest confidence index, while those who wanted to try a new method had the lower confidence index.CONCLUSION: Acupuncture for smoking cessation was more popular in female smokers, especially those aged 31-40 years. The effectiveness of acupuncture-smoking cessation was most significant in the smokers over 60. | Wang Yingying Liu Zhao Zhang Ou Chen Min Huang Lingling Wu Yuan Zhang Fanfan Wu Guanyi He Xiuqing Yang Jinsheng | 2016 | Journal of Traditional Chinese Medicine2016，36，5： | 3 |
| 6 | Review of ionospheric irregularities and ionospheric electrodynamic coupling in the middle latitude region显示文摘This paper briefly reviews ionospheric irregularities that occur in the E and F regions at mid-latitudes. Sporadic E(ES) is a common ionospheric irregularity phenomenon that is first noticed in the E layer. ES mainly appears during daytime in summer hemispheres, and is formed primarily from neutral wind shear in the mesosphere and lower thermosphere(MLT) region. Field-aligned irregularity(FAI) in the E region is also observed by Very High Frequency(VHF) radar in mid-latitude regions. FAI frequently occurs after sunset in summer hemispheres, and spectrum features of E region FAI echoes suggest that type-2 irregularity is dominant in the nighttime ionosphere. A close relationship between ES and E region FAI implies that ES may be a possible source of E region FAI in the nighttime ionosphere. Strong neutral wind shear, steep ES plasma density gradient, and a polarized electric field are the significant factors affecting the formation of E region FAI. At mid-latitudes, joint observational experiments including ionosonde, VHF radar, Global Positioning System(GPS) stations, and all-sky optical images have revealed strong connections across different scales of ionospheric irregularities in the nighttime F region, such as spread F(SF), medium-scale traveling ionospheric disturbances(MSTID), and F region FAI.Observations suggest that different scales of ionospheric irregularities are generally attributed to the Perkins instability and subsequently excited gradient drift instability. Nighttime MSTID can further evolve into small-scale structures through a nonlinear cascade process when a steep plasma density gradient exists at the bottom of the F region. In addition, the effect of ionospheric electrodynamic coupling processes, including ionospheric E-F coupling and inter-hemispheric coupling on the generation of ionospheric irregularities, becomes more prominent due to the significant dip angle and equipotentiality of magnetic field lines in the mid-latitude ionosphere. Polarized electric fields can map to different ionospheric regions and excite plasma instabilities which form ionospheric irregularities. Nevertheless,the mapping efficiency of a polarized electric field depends on the ionospheric background and spatial scale of the field. | Yi Liu Chen Zhou Tong Xu Qiong Tang ZhongXin Deng GuanYi Chen ZhuangKai Wang | 2021 | Earth and Planetary Physics2021，5，5： | 2 |
