| 1 | Promoting effect of microwave irradiation on CeO2-TiO2 catalyst for selective catalytic reduction of NO by NH3显示文摘In this work we prepared several CeO2-TiO2 catalysts for the NH3-SCR reactionusing co-precipitation with assistance of microwave irradiation.The catalytic NH3-SCR activities over CeO2-TiO2 catalysts at low temperatures are largely enhanced by the treatment of microwave irradiation,the operation temperature window is also broadened.For better understanding the promotion mechanism,the catalyst prepared by conventional co-precipitation with and without microwave irradiation treatment was characterized with H2-TPR,NH3-TPD,XPS,XRD and BET.Microwave irradiation treatment accelerates the crystallite rate of CeO2-TiO2 catalysts,and greatly enlarges their surface area by adjusting their microstructures.The resistance to SO2 and H2O is also improved via regulating the hierarchical pore structure by the microwave irradiation.Microwave irradiation treatment can also improve the redox property and increase the acid sites over the catalyst surfaces.The result of in situ DRIFTS suggests that the microwave irradiation treatment generates more Br?nsted acid sites on CeO2-TiO2-2 h catalyst,helpful in SCR reactions.XPS results show that after microwave irradiation on the CeO2-TiO2 catalysts,the surface demonstrates an elevated concentration of chemisorbed oxygen,consequently leading to better oxidation of NO to NO2.Additionally,the molar ratio of Ce3+/Ce4+has been elevated after being treated by microwave irradiation,a vital factor in enhancing the NH3-SCR activities. | Jie Cheng Liyun Song Rui Wu Shining Li Yanming Sun Hongtai Zhu Wenge Qiu Hong He | 2020 | Journal of Rare Earths2020,38,1: | 11 |
| 2 | Using big data to track marine oil transportation along the 21st-century Maritime Silk Road显示文摘China's designation of the '21 st-century Maritime Silk Road'(MSR) region is of extraordinary significance to its maritime rights, transportation security, and socio-economic development. We developed a technical framework allowing the use of 'big data' derived from the Automatic Identification System(AIS, an automatic ship-tracking network) for two purposes: the accurate mapping of oil tanker trajectories and the creation of heat maps showing the relative use of oil tanker routes and marine shipping chokepoints. We then applied these methods to 1.5 billion AIS records collected within the MSR in 2014 to statistically identify and analyze busy routes, areas, and chokepoints in this strategic region. Our results demonstrate that the proposed framework can provide an effective analysis of oil movements based on large-scale AIS datasets, helping researchers and policy makers better understand the footprint and strategic implications of maritime oil transportation in the MSR region. | CHENG Liang YAN ZhaoJin XIAO YiJia CHEN YanMing ZHANG FangLi LI ManChun | 2019 | Science China(Technological Sciences)2019,62,4: | 3 |

| 10 | Magnetism and work function of Ni-Cu alloys as metal gates显示文摘The magnetism and work function of pure Ni(001) and Ni-Cu slab alloys were investigated using first-principles methods based on density functional theory. The calculated results reveal that both magnetic moments and work functions of the alloys depend strongly on the surface orientation, but hardly on the distribution of doped Cu atoms for a given surface orientation. It is found that the doped Cu atoms have evident influence on the magnetic moment of Ni-Cu slabs, and the average magnetic moment of Ni atoms for Ni-Cu alloys decreases with increasing concentration of Cu atoms. Moreover, it is observed that the work function of Ni(001) is insensitive to the supercell thickness and the inner concentration of Cu atoms. In the meantime, the spin polarization is found to have an obvious role on the work function of the Ni-Cu alloys, which may give a new way to modulate the work function of the metal gate. | Cheng, Yanming Zheng, Yongping Huang, Xu Zhong, Kehua Chen, Zhigao Huang, Zhigao | 2012 | Rare Metals2012,31,2: | 1 |

| 13 | A Deep Learning Approach to Shape Optimization Problems for Flexoelectric Materials Using the Isogeometric Finite Element Method显示文摘A new approach for flexoelectricmaterial shape optimization is proposed in this study.In this work,a proxymodel based on artificial neural network(ANN)is used to solve the parameter optimization and shape optimization problems.To improve the fitting ability of the neural network,we use the idea of pre-training to determine the structure of the neural network and combine different optimizers for training.The isogeometric analysis-finite element method(IGA-FEM)is used to discretize the flexural theoretical formulas and obtain samples,which helps ANN to build a proxy model from the model shape to the target value.The effectiveness of the proposed method is verified through two numerical examples of parameter optimization and one numerical example of shape optimization. | Yu Cheng Yajun Huang Shuai Li Zhongbin Zhou Xiaohui Yuan Yanming Xu | 2024 | Computer Modeling in Engineering & Sciences2024,139,5: | 0 |
| 14 | Seasonal variations in the composition and functional profiles of gut microbiota reflect dietary changes in plateau pikas显示文摘Seasonal variations in gut microbiota of small mammals and how they are influenced by environmental variables are relatively poorly understood.We sampled 162 wild plateau pikas(Ochotona curzoniae)in 4 seasons over 2 and a half years and recorded the air temperature,precipitation,and nutrient content in edible vegetation at the sampling site.After conducting 16S rRNA and shotgun metagenomic sequencing,we found that the highest alpha diversity,the relative abundance of Firmicutes,and the simplest co-occurrence network occurred in winter,whereas the highest relative abundance of Proteobacteria and the most complex network structure were observed in spring.The highest relative abundance of Verrucomicrobiota and Spirochaetota was seen in summer and autumn,respectively.Air temperature,precipitation,and the contents of crude protein,crude fiber,and polysaccharide in vegetation had significant effects on the seasonal changes in gut microbiota.Diet contributed more to microbial variation than climatic factors.Metagenomic analysis revealed that the amino acid metabolism pathway and axillary activity enzymes were most abundant in summer,while abundance of carbohydrate-binding modules and carbohydrate esterases was highest in spring.These microbial variations were related to the changes in dietary nutrition,indicating that gut microbiota of plateau pika contribute to the efficient use of food resources.This study provides new evidence of how external environmental factors affect the intestinal environment of small mammals. | Chao FAN Liangzhi ZHANG Shangang JIA Xianjiang TANG Haibo FU Wenjing LI Chuanfa LIU He ZHANG Qi CHENG Yanming ZHANG | 2022 | Integrative Zoology2022,17,3: | 0 |
| 15 | A novel role of LRP5 in tubulointerstitial fibrosis through activating TGF-β/Smad signaling显示文摘Previous studies by us and others demonstrated that activation of Wnt/β-catenin signaling plays a pathogenic role in chronic kidney diseases(CKD).Wnt co-receptor LRP5 variants are reported to associate with autosomal dominant polycystic kidney disease;but their exact roles in this disease and renal fibrosis have not been explored.Here,we observed the upregulation of LRP5 in the renal tubules of both type 1 and type 2 diabetic models and of an obstructive nephropathy model.In the obstructed kidneys,Lrp5 knockout significantly ameliorated tubulointerstitial fibrosis and tubular injury without changing Wnt/β-catenin signaling.Instead,decreased levels of TGF-β1 and TGF-βreceptors(TβRs)were detected in Lrp5 knockout kidneys,followed by attenuated activation and nuclear translocation of Smad2/3 in the renal tubules,suggesting a regulatory effect of LRP5 on TGF-β/Smad signaling.In consistent with this hypothesis,LRP5 overexpression resulted in enhanced TGF-β/Smad signaling activation in renal tubule epithelial cells.Furthermore,LRP5 was co-immunoprecipitated with TβRI and TβRII,and its extracellular domain was essential for interacting with TβRs and for its pro-fibrotic activity.In addition to stabilizing TβRs,LRP5 increased the basal membrane presentation and TGF-β1-induced internalization of these receptors.Notably,TGF-β1 also induced LRP5 internalization.These findings indicate that LRP5 promotes tubulointerstitial fibrosis,at least partially,via direct modulation of TGF-β/Smad signaling,a novel,Wnt-independent function. | Xuemin He Rui Cheng Chao Huang Yusuke Takahashi Yanhui Yang Siribhinya Benyajati Yanming Chen Xin AZhang Jian-xing Ma | 2020 | Signal Transduction and Targeted Therapy2020,5,1: | 0 |
| 16 | Tuning the Corrosion Resistance,Antibacterial Activity,and Cytocompatibility by Constructing Grooves on the Surface of Ti6Al4V3Cu Alloy显示文摘Ti6Al4V3Cu alloy is a promising biomaterial for combating implant-related infection.However,the antibacterial property of Ti6Al4V3Cu is expected to be enhanced due to the low content of Cu element in titanium.To address this issue,the antibacterial property of Ti6Al4V3Cu was tailored by the grooves with different groove widths(30μm,60μm,and 90μm)that were constructed on the surface of the Ti6Al4V3Cu by selective laser melting.The effect of grooves on corrosion resistance,antibacterial property,and cytocompatibility was investigated.The electrochemical tests showed that the corrosion resistance decreased with increasing groove width.The antibacterial tests indicated that the groove with a width of 30μm and 90μm groups showed better antibacterial activity against S.aureus(>90%)compared with the groove with a width of 60μm.The in vitro study suggested that all samples with different grooves were found to exhibit good cytocompatibility with osteoblast cells.It is considered that creating grooves on Ti6Al4V3Cu by selective laser melting is a promising strategy to enhance the antibacterial activity without sacrificing cytocompatibility. | Minghui Zhou Hui Sun Yanming Gan Cheng Ji Yan Chen Yanjin Lu Jinxin Lin Qiang Wang | 2023 | Acta Metallurgica Sinica(English Letters)2023,36,12: | 0 |
| 17 | Non-fullerene acceptor pre-aggregates enable high efficiency pseudo-bulk heterojunction organic solar cells显示文摘Pseudo-bulk heterojunction(BHJ)fabricated by sequential casting of donor and acceptor layers has been recently demonstrated as a superior structure to prepare organic solar cells(OSCs)with enhanced efficiency compared to the conventional BHJ OSCs cast from a common solution of donors and acceptors.However,molecular diffusion and aggregation within the pseudo-BHJ layer bring great challenges to fully realize the advantage of pseudo-BHJ structure.Herein,a solution-incubated pre-aggregation strategy is employed to tune the nanoscale aggregates of non-fullerene acceptor(NFA)BTP-e C11 and N3 to substantially enhance device power-conversion efficiency(PCE).NFA pre-aggregates are incubated in solutions via aging or adding antisolvent,and then sequentially cast onto D18 fibrillar network,which then penetrate to form a pseudo-BHJ structure with appropriate domain sizes to ensure superior charge mobilities.While the conventional pseudo-BHJ OSCs obtain inferior PCEs below 17%compared with normal BHJ OSCs,NFA pre-aggregates help to achieve remarkable PCEs of 17.7%and 17.5%for D18/BTP-e C11 and D18/N3 pseudo-BHJ OSCs.This work demonstrates that the solution-incubated nanoscale pre-aggregation is an efficient approach to regulate molecular diffusion and aggregation to guarantee high performance pseudo-BHJ OSCs. | Donghui Li Chuanhang Guo Xue Zhang Baocai Du Cong Yu Pang Wang Shili Cheng Liang Wang Jinlong Cai Hui Wang Dan Liu Huifeng Yao Yanming Sun Jianhui Hou Tao Wang | 2022 | Science China Chemistry2022,65,2: | 0 |
| 18 | Identification of the receptor of oncolytic virus M1 as a therapeutic predictor for multiple solid tumors显示文摘Over the last decade,oncolytic virus(OV)therapy has shown its promising potential in tumor treatment.The fact that not every patient can benefit from it highlights the importance for defining biomarkers that help predict patients’responses.As particular self-amplifying biotherapeutics,the anti-tumor effects of OVs are highly dependent on the host factors for viral infection and replication.By using weighted gene co-expression network analysis(WGCNA),we found matrix remodeling associated 8(MXRA8)is positively correlated with the oncolysis induced by oncolytic virus M1(OVM). | Deli Song Xudong Jia Xincheng Liu Linyi Hu Kaiying Lin Tong Xiao Yangyang Qiao Jiayu Zhang Jia Dan Chunwa Wong Cheng Hu Ke Sai Shoufang Gong Max Sander Runling Shen Xiaoyu Chen Xiaoting Xiao Jiehong Chen Yanming Zhang Cailv Wei Xiao Xiao Jiankai Liang Qinfen Zhang Jun Hu Wenbo Zhu Guangmei Yan Yuan Lin Jing Cai | 2022 | Signal Transduction and Targeted Therapy2022,7,5: | 0 |
