Herein,a one-step co-pyrolysis protocol was adopted for the first time to prepare a novel pyrogenic carbon-Cu^(0)/Fe_(3)O_(4)heteroatoms (FCBC) in CO_(2)ambiance to discern the roles of each component in PDS activation.During co-pyrolysis,CO_(2)catalyzed formation of reducing gases by biomass which facilitated reductive transformation of Fe^(3+)and Cu^(2+)to Cu^(0)and Fe_(3)O_(4),respectively.According to the analysis,the resulting metal (oxide) catalyzed graphitization of biocharand decomposition of volatile substances resulting in an unprecedented surface area (1240 m^(2)/g).The resulting FCBC showed greater structural defects and less electrical impedance.Batch experiments indicated that Rhodamine B (RhB) degradation by FCBC (100%) was superior to Fe_(3)O_(4)(50%) and Cu^(0)/Fe_(3)O_(4)(76.4%) in persulfate (PDS) system,which maintained reasonable efficiency (75.6%-63.6%) within three cycles.The reactive oxygen species (ROS) associated with RhB degradation was identified by an electron paramagnetic resonance and confirmed by scavenging experiments.RhB degradation invoked both(sulfate and dominantly hydroxyl) radical and non-radical (singlet oxygen,^(1)O_(2)) pathways.Regarding FCBC,Cu^(0)can continuously react with Fe^(3+)in Fe_(3)O_(4)to generate larger quantities of Fe^(2+),and both Cu^(0)and Fe^(2+)activated PDS to yield sulfate radicals which was quickly converted to hydroxyl radical.Besides,Cu^(0)/Cu^(2+)could complex with PDS to form a metastable complex,which particularly contributed to1O_(2)generation.These cascade reactions by FCBC were reinforced by carbonyl group of biochar and favorable electron transfer ability.This work highlighted a new approach to prepare a magnetic and environment-benign heterogonous catalyst to remove organic pollutants in water.

Computation on Sentence Semantic Distance for Novelty Detection

引用

Journal of Computer Science & Technology 2005年第3期20卷 331-337页

作者： Hua-PingZhang JianSun bingwang ShuoBai InstituteofComputingTechnology ChineseAcademyofSciencesBeijing100080P.R.China／／GraduateSchooloftheChineseAcademyofSciencesBeijing100039P.R.China InstituteofComputingTechnology ChineseAcademyofSciencesBeijing100080P.R.China

Novelty detection is to retrieve new information and filter redundancy fromgiven sentences that are relevant to a specific topic. In TREC2003, the authors tried an approach tonovelty detection with semantic distance computation. The motivation is to expand a sentence byintroducing semantic information. Computation on semantic distance between sentences incorporatesWordNet with statistical information. The novelty detection is treated as a binary classificationproblem: new sentence or not. The feature vector, used in the vector space model for classification,consists of various factors, including the semantic distance from the sentence to the topic and thedistance from the sentence to the previous relevant context occurring before it. New sentences arethen detected with Winnow and support vector machine classifiers, respectively. Several experimentsare conducted to survey the relationship between different factors and performance. It is provedthat semantic computation is promising in novelty detection. The ratio of new sentence size torelevant size is further studied given different relevant document sizes. It is found that the ratioreduced with a certain speed (about 0.86). Then another group of experiments is performedsupervised with the ratio. It is demonstrated that the ratio is helpful to improve the noveltydetection performance.

For urban wastewater treatment,we conducted a novel four-stage step-feed wastewater treatment system combined with a fluidized bed laboratory experiment to investigate chemical oxygen demand（COD）,NH4＋-N,and total nitrogen（TN） removal performance.The removal rates of COD,NH4＋-N and TN were 88.2%,95.7%,and 86.4% with e？uent concentrations of COD,NH4＋-N and TN less than 50,8,and 10 mg/L,respectively.Biomass and bacterial activities were also measured,with results showing more nitrobacteria in the activated sludge than in the biofilm;however,bacterial activity of the biofilm biomass and the activated sludge were similar.Nitrogen concentrations during the process were also detected,with simultaneous nitrification and denitrification found to be obvious.

Environmental Efficiency and the Optimal Size of Chinese Cities

China & World Economy 2017年第3期25卷 60-86页

The spatial distribution of population and economic activities has tmportant tmpacts onboth economic growth and the environment. This paper uses a slack-based measure toestimate the total factor environmental efficiency （TFEE） of 286 Chinese prefectural-and-above cities for the period 2002-2013. In particular, the relationship between citysize and TFEE is investigated. The findings also show an inverted U-shaped relationshipbetween TFEE and city size, which implies an optimal city size of 16.68 million residentsin China. According to this estimate, most Chinese cities may be undersized due to themigration restrictions of the hukou registration system and, hence, suffer from greatenvironmental efficiency losses. The estimated low average TFEE value of Chinese citiesalso suggests the large potential for efficiency improvement. Thus, government policiesshould focus on relaxing migration restrictions and encouraging the development oflarge cities.

为提高煤矿企业的经济效益,合理安排各项安全投入,构建一种解决指标间相关性的模型。首先,剖析基于安全投入的经济效益的影响因素,在此基础上构建一套较为科学合理的结构指标体系;其次,利用熵权法确定各个指标的权重;然后,针对指标之间存在的相关性,基于安全投入结构,引入熵权-基于2-可加模糊测度的Choquet模糊积分模型,计算经济效益评价值;最后,选取某煤矿进行实证分析,验证所构建模型的可行性和有效性。结果表明:所构建的模型比逼近理想解排序(TOPSIS)法更具有可靠性;该模型考虑指标之间相互影响、相互关联情况,能够得到较为准确、科学的评价结果。

为了解决复杂环境下基于单一舰船信息进行目标识别准确率较低,以及多源舰船信息高冲突时无法有效融合识别的问题,提出一种基于深度学习和改进证据理论的海上多源舰船信息融合识别方法。主要从两方面入手:首先利用深度学习高效特征学习能力实现更加准确的分类识别;然后通过改进的证据理论实现多证据体的高效正确融合。高悖论证据融合实验结果表明,相比于其他融合方法,文中方法融合结果具有更高的概率分配值。同时,在不同信噪比条件下对单模式识别以及文中融合识别方法进行测试,文中方法在噪声情况下仍能比单模式平均水平高出6.53%的识别性能。因此,利用文中融合识别方法能够提高舰船目标识别系统的识别准确率和鲁棒性。

Epitaxial growth of highly strained antimonene on Ag（111）

引用

Frontiers of physics 2018年第3期13卷 61-68页

作者： Ya-Hui Mao Li-Fu Zhang Hui-Li Wang Huan Shan Xiao-Fang Zhai Zhen-Peng Hu Ai-Di Zhao bingwang Hefei National Laboratory for Physical Sciences at the Microscale and Synergetic Innovation Center of Quantum Information & Quantum Physics University of Science and Technology of China Hefei 230026 China School of Physics Nankai University Tianjin 300071 China

The synthesis of antimonene, which is a promising group-V 2D material for both fundamental studies and technological applications, remains highly challenging. Thus far, it has been synthesized only by exfoliation or growth on a few substrates. In this study, we show that thin layers of antimonene can be grown on Ag（111） by molecular beam epitaxy. High-resolution scanning tunneling microscopy combined with theoretical calculations revealed that the submonolayer Sb deposited on a Ag（111） surface forms a layer of AgSb2 surface alloy upon annealing. Further deposition of Sb on the AgSb2 surface alloy causes an epitaxial layer of Sb to form, which is identified as antimonene with a buckled honeycomb structure. More interestingly, the lattice constant of the epitaxial antimonene （5 /-） is much larger than that of freestanding antimonene, indicating a high tensile strain of more than 20%. This kind of large strain is expected to make the antimonene a highly promising candidate for room- temperature quantum spin Hall material.
