| 1 | Whole-Process Pollution Control for Cost-Effective and Cleaner Chemical Production A Case Study of the Tungsten Industry in China显示文摘In this research,a methodology named whole-process pollution control(WPPC)is demonstrated that improves the effectiveness of process optimization.This methodology considers waste/emission treatment as a step of the whole production process with respect to the minimization of cost and environmental impact for the whole process.The following procedures are introduced in a WPPC process optimization:①a material and energy flow investigation and optimization based on a systematic understanding of the distribution and physiochemical properties of potential pollutants;②a process optimization to increase the utilization efficiency of different elements and minimize pollutant emissions;and③an evaluation to reveal the effectiveness of the optimization strategies.The production of ammonium paratungstate was chosen for the case study.Two factors of the different optimization schemes-namely the cost-effectiveness factor and the environmental impact indicator-were evaluated and compared.This research demonstrates that by considering the nature of potential pollutants,technological innovations,economic viability,environmental impacts,and regulation requirements,WPPC can efficiently optimize a metal production process. | Hongbin Cao He Zhao Di Zhang Chenming Liu Xiao Lin Yuping Li Pengge Ning Jiajun Sun Yi Zhang Zhi Sun | 2019 | Engineering2019，5，4： | 7 |
| 2 | Internal failure of anode materials for lithium batteriesd——A critical review显示文摘Prevention of mechanical and finally electrochemical failures of lithium batteries is a critical aspect to be considered during their design and performance, especially for those with high specific capacities. Internal failure is observed as one of the most serious factors, including loss of electrode materials, structure deformation and dendrite growth. It usually incubates from atomic/molecular level and progressively aggravates along with lithiation. Understanding the internal failure is of great importance for developing solutions of failure prevention and advanced anode materials. In this research, different internal failure processes of anode materials for lithium batteries are discussed. The progress on observation technologies of the anode failure is further summarized in order to understand their mechanisms of internal failure. On top of them, this review aims to summarize innovative methods to investigate the anode failure mechanisms and to gain new insights to develop advanced and stable anodes for lithium batteries. | Xiangqi Meng Yaolin Xu Hongbin Cao Xiao Lin Pengge Ning Yi Zhang Yaiza Gonzalez Garcia Zhi Sun | 2020 | Green Energy & Environment2020，5，1： | 5 |
| 3 | Modeling for tungstic precipitation and extraction based on Pitzer equation显示文摘This work presented the results of tungstic precipitation from Na_2WO_4-Na_2SO_4-H_2O system at 293.15 K, with which the Pitzer parameters of β_(Na2WO4)^(0) and β(Na2WO4)^(1) were determined from Pitzer equation by regression. Thus the mean ionic activity coefficients of sodium tungstate were calculated. The obtained β_(Na2WO4)^(0) and β(Na2WO4)^(1) were substituted as fixed values in extraction modeling from Na_2WO_4-H_2SO_4-H_2O system by primary amine(N1923) in toluene as diluent. Meanwhile the activity coefficient expressions in organic phase were varied based on Pitzer theory that the interaction term for the solvent should not be included. The Pitzer parameters for organic phase were re-regressed in order to make the model more accurate. The average absolute relative deviation(AARD) for calculated and experimental molality of WO_4~(2-) in aqueous phase was 5.24%. The results showed that the model can not only correlate but also predict the liquid-liquid equilibrium(LLE) data. | Xinyue Zhang Pengge Ning Weifeng Xu Hongbin Cao Yi Zhang | 2016 | Science China Chemistry2016，59，4： | 2 |
| 4 | Thermodynamic models based on Pitzer-NRTL and Pitzer-Margules equations for the extraction of tungstic acid with primary amine N1923显示文摘The thermodynamic model of the extraction of W with primary amine under near neutral conditions is reported in this paper. The activity coefficients of the nonelectrolytes in organic phase are calculated by the Margules and NRTL equations which are based on previously tested liquid-liquid extraction equilibrium data in combination with mass balances and charge balance formula. The activity coefficients of the electrolytes in aqueous phase are calculated by the Pitzer equation. The thermodynamic model of the extraction of W by a primary amine is constructed from the calculated activity coefficients of electrolytes and nonelectrolytes. The extraction of W using primary amine is also predicated, and the data is compared to the calculated results of the thermodynamic model. It is concluded that Margules equation proves to be suitable and reliable for calculating the activity coefficients of nonelectrolytes in complex organic phase systems. | LIN Xiao NING PengGe XU WeiFeng CAO HongBin ZHANG Yi | 2015 | Science China(Technological Sciences)2015，58，5： | 1 |
| 5 | Collaborative representation with background purification and saliency weight for hyperspectral anomaly detection显示文摘Collaborative representation-based detection(CRD)has been developed in hyperspectral anomaly detection tasks and testified to be very effective;however,heterogeneous pixels in the background may affect the accuracy of linear representation and make its performance suboptimal.To address this issue,a background purification framework based on linear representation is proposed,in which an automatic outlier removal strategy based on initial coefficients is designed to purify the background.In the proposed method,the classic least squares technique is firstly adopted to obtain preliminary linear representation coefficients,which are positively correlated with its contribution to a central testing pixel.Then,using statistical analysis of the representation coefficients,purified background pixels are obtained.Furthermore,a saliency weight is applied to fully utilize the spatial information of inner window pixels.Extensive experiments with three real hyperspectral datasets show that the proposed method outperforms state-of-the-art CRD and other traditional detectors. | Zengfu HOU Wei LI Ran TAO Pengge MA Weihua SHI | 2022 | Science China(Information Sciences)2022，65，1： | 1 |

| 7 | Design of solvent mixtures for removal of phenol from wastewater using a non-linear programming model with a multi-start method显示文摘The optimization-based design of solvent mixtures used for phenolic wastewater treatment was investigated in this work.A nonlinear programming(NLP)model was formulated based on the concepts of computer-aid molecule design(Computer-Aided Molecular Design,CAMD)to select solvent mixtures with the best extraction performance considering the constraints of extraction process and the environmental impact.Due to the complexity of the NLP model,multi-start method was adopted to solve this problem in order to get near global optimal solution.The results of the calculations suggested that the optimal mixture consisted of 70.1%n-octanol and 29.9%2-octanone(molar fraction).The 119 sets of experimental results showed that the extraction ability of the optimal solvent mixture identified by CAMD technique was among the top 6 sets compared to the experiment results.The results suggested that the developed NLP model could be able to screen the optimal solvent mixture in phenolic wastewater treatment. | Qingjie Wang Yanchun Shi Yuehong Zhao Pengge Ning | 2022 | Emerging Contaminants2022，8，1： | 1 |

| 16 | Comparison between inhibitor and uncoupler for minimizing excess sludge production of an activated sludge process显示文摘In order to study the minimization of excess sludge production,the reduction in the excess sludge production in the presence of an inhibitor and uncoupler was studied in this work.The experimental results show that such an addition could effectively reduce the production of excess sludge.With the energy uncoupling model established in this work,energy uncoupling coefficient(Eu)was used to evaluate the reduction in excess sludge production.The energy uncoupling coefficients in the presence of dinitrophenol(dNP),Zn^(2+),and Cu^(2+)was 0.75,0.46,and 0.18,respectively.The analysis demonstrated that energy spilling occurred in the presence of dNP,and that dNP was an effective uncoupler for reducing the production of excess activated sludge without affecting the microbial respiration activity. | CHEN Guowei XI Pengge XU Deqian YU Hanqing | 2007 | Frontiers of Environmental Science & Engineering2007，1，1： | 1 |
| 17 | Improved Weighted Local Contrast Method for Infrared Small Target Detection显示文摘In order to address the problem of high false alarm rate and low probabilities of infrared small target detection in complex low-altitude background,an infrared small target detection method based on improved weighted local contrast is proposed in this paper.First,the ratio information between the target and local background is utilized as an enhancement factor.The local contrast is calculated by incorporating the heterogeneity between the target and local background.Then,a local product weighted method is designed based on the spatial dissimilarity between target and background to further enhance target while suppressing background.Finally,the location of target is obtained by adaptive threshold segmentation.As experimental results demonstrate,the method shows superior performance in several evaluation metrics compared with six existing algorithms on different datasets containing targets such as unmanned aerial vehicles(UAV). | Pengge Ma Jiangnan Wang Dongdong Pang Tao Shan Junling Sun Qiuchun Jin | 2024 | Journal of Beijing Institute of Technology2024，33，1： | 0 |
| 18 | Characterization strategy of polymeric transition metal species transformation for high-purity metal recovery显示文摘The aqueous metal species with similar chemical properties are usually extracted together,limiting deep separation for high-purity metal.However,rare attention has been paid to metal speciation characterization and transformation during separation.Herein,the hydrolysis evolution of polymeric metal species was investigated systematically by electrospray ionization time-of-flight mass spectrometry(ESI-TOF-MS).The transformation evolutions were visualized with respect to characteristic vanadium species(V_(1),V_(2),V_(3),V_(4) and V_(10)),chromium species(Cr_(1) and Cr_(2)),tungsten(W_(1),W_(2),W_(4),W_(6) and W_(10))and molybdenum(Mo_(1),Mo_(2) and Mo_(4))species.The key characteristics(such as specfic pHs and concentrations)for speciation variation were revealed.The polymerization behavior of several transition metals can be semiquantitative characterized by this strategy.The sufficient speciation transformation provides a solid base for metal speciation chemistry,and guides further development of high-purity metal recovery. | Jiawei Wen Yan Wu Shujie Lin Pengge Ning | 2021 | Green Chemical Engineering2021，2，3： | 0 |
| 19 | Conversion of phenol to cyclohexane in the aqueous phase over Ni/zeolite bi-functional catalysts显示文摘A series of Ni/HZSM-5 and Ni/HIM-5 bi-functional catalysts were synthesized and applied to the aqueous-phase hydrodeoxygenation(HDO)of phenol.The Ni dispersibility and particle sizes were shown to be directly related to the porosity and crystal sizes of the parent zeolites,which further influenced the catalytic performances.The large pores and small crystal sizes of the parent zeolites were beneficial for dispersing Ni and forming small Ni particles,and the corresponding Ni/zeolite catalyst exhibited a higher phenol conversion and selectivity towards hydrocarbons.Importantly,the Ni/HIM-5 bi-functional catalyst exhibited a high activity(98.3%)and high selectivity for hydrocarbons(98.8%)when heated at 220°C for 1 h and is thus a new potential catalyst for the HDO of phenolics to form hydrocarbons in the aqueous phase. | Jimei Zhang Fuping Tian Junwen Chen Yanchun Shi Hongbin Cao Pengge Ning Shanshan Sun Yongbing Xie | 2021 | Frontiers of Chemical Science and Engineering2021，15，2： | 0 |
| 20 | Design and experiment of intelligent sorting and transplanting system for healthy vegetable seedlings显示文摘Healthy vegetable seedlings are surviving seedlings with good biological characteristics.Selective planting of healthy seedlings in the mechanized transplanting process can effectively avoid the reduction in yield caused by missed planting.Aiming at the current transplanting machinery that cannot achieve the selective planting of healthy seedlings,a healthy seedling intelligent sorting and transplanting system was proposed.The system consisted of a seedling delivery mechanism,sorting mechanism,photoelectric sensor,image sensor,PLC control system,and computer control system.It can realize automatic transmission of seedling trays,automatically identify the information of healthy seedlings in the trays and selectively transplant them.Also it can reduce the missed planting rate caused by the poor quality of plug seedlings after planting and the lack of seedlings in the hole.A sorting test of plug seedlings was carried out for the age-appropriate pepper plug seedlings cultivated in the factory.The results showed that the system had an average recognition accuracy rate of 89.14%and an average sorting success rate of 93.20%in the process of sorting suitable age pepper plug seedlings.The whole system can identify,sort and transplant the plug seedlings of appropriate age according to healthy information,and effectively avoid missing planting.This research can provide technical support for the intelligent upgrade of transplanting equipment. | Mingyong Li Xin Jin Jiangtao Ji Pengge Li Xinwu Du | 2021 | International Journal of Agricultural and Biological Engineering2021，14，4： | 0 |
