| 1 | Application of P507 and isooctanol extraction system in recovery of scandium from simulated red mud leach solution显示文摘The current recovery technique of Sc was complicated and the chemical consumption was high,This was due to the low content of Sc in resources and the difficulty of stripping.In this research,the isooctanol was added into the 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester(P507)extraction system to reduce the extraction and improve the stripping of Sc.The maximum stripping ratio of Sc from loaded organic phase by sulfuric acid can increase from 10%(without isooctanol)to 99%(with 15 vol%isooctanol).In the extraction test of the simulated red mud leaching liquor,the separation factors between Sc and Zr,Sc and Ti are 36 and 350,separately.At the same time,other metals are almost not extracted.The high selectivity and stripping of Sc suggest that the P507 with isooctanol extraction system can be applied in the practical Sc recovery process. | Chuanying Liu Li Chen Ji Chen Dan Zou Yuefeng Deng Deqian Li | 2019 | Journal of Rare Earths2019,37,9: | 22 |
| 2 | Simultaneous changes in seed size, oil content and protein content driven by selection of SM/EEIhomologues during soybean domestication显示文摘Soybean accounts for more than half of the global production of oilseed and more than a quarter of the protein used globally for human food and animal feed.Soybean domestication involved parallel increases in seed size and oil content,and a concomitant decrease in protein content.However,science has not yet discovered whether these effects were due to selective pressure on a single gene or multiple genes.Here,re-sequencing data from>800 genotypes revealed a strong selection during soybean domestication on GmSWEETlOa.The selection of GmSWEETlOa conferred simultaneous increases in soybean-seed size and oil content as well as a reduction in the protein content.The result was validated using both near-isogenic lines carrying substitution of haplotype chromosomal segments and transgenic soybeans.Moreover,GmSWEETlOb was found to be functionally redundant with its homologue GmSWEETlOa and to be undergoing selection in current breeding,leading the the elite allele GrnSWEETlOb,a potential target for present-day soybean breeding.Both GmSWEETlOa and GmSWEETlOb were shown to transport sucrose and hexose,contributing to sugar allocation from seed coat to embryo,which consequently determines oil and protein contents and seed size in soybean.We conclude that past selection of optimal GmSWEETlOa alleles drove the initial domestication of multiple soybean-seed traits and that targeted selection of the elite allele GmSWEETlOb may further improve the yield and seed quality of modern soybean cultivars. | Shoudong Wang Shulin Liu Jie Wang Kengo Yokosho Bin Zhou Ya-Chi Yu Zhi Liu Wolf BFrommer Jian Feng Ma Li-Qing Chen Yuefeng Guan Huixia Shou Zhixi Tian | 2020 | National Science Review2020,7,11: | 17 |

| 4 | Paleoclimate Modeling in China: A Review显示文摘This paper provides a review of paleoclimate modeling activities in China. Rather than attempt to cover all topics, we have chosen a few climatic intervals and events judged to be particularly informative to the international community. In historical climate simulations, changes in solar radiation and volcanic activity explain most parts of reconstructions over the last millennium prior to the industrial era, while atmospheric greenhouse gas concentrations play the most important role in the20 th century warming over China. There is a considerable model–data mismatch in the annual and boreal winter temperature change over China during the mid-Holocene [6000 years before present(ka BP)], while coupled models with an interactive ocean generally perform better than atmospheric models. For the Last Glacial Maximum(21 ka BP), climate models successfully reproduce the surface cooling trend over China but fail to reproduce its magnitude, with a better performance for coupled models. At that time, reconstructed vegetation and western Pacific sea surface temperatures could have significantly affected the East Asian climate, and environmental conditions on the Qinghai–Tibetan Plateau were most likely very different to the present day. During the late Marine Isotope Stage 3(30–40 ka BP), orbital forcing and Northern Hemisphere glaciation, as well as vegetation change in China, were likely responsible for East Asian climate change. On the tectonic scale,the Qinghai–Tibetan Plateau uplift, the Tethys Sea retreat, and the South China Sea expansion played important roles in the formation of the East Asian monsoon-dominant environment pattern during the late Cenozoic. | JIANG Dabang YU Ge ZHAO Ping CHEN Xing LIU Jian LIU Xiaodong WANG Shaowu ZHANG Zhongshi YU Yongqiang LI Yuefeng JIN Liya XU Ying JU Lixia ZHOU Tianjun YAN Xiaodong | 2015 | Advances in Atmospheric Sciences2015,32,2: | 12 |
| 5 | 5G Flexible Optical Transport Networks with Large-Capacity, Low-Latency and High-Efficiency显示文摘The fifth generation(5G) of mobile communications are facing big challenges, due to the proliferation of diversified terminals and unprecedented services such as internet of things(IoT), high-definition videos, virtual/augmented reality(VR/AR). To accommodate massive connections and astonish mobile traffic, an efficient 5G transport network is required. Optical transport network has been demonstrated to play an important role for carrying 5G radio signals. This paper focuses on the future challenges, recent studies and potential solutions for the 5G flexible optical transport networks with the performances on large-capacity, low-latency and high-efficiency. In addition, we discuss the technology development trends of the 5G transport networks in terms of the optical device, optical transport system, optical switching, and optical networking. Finally, we conclude the paper with the improvement of network intelligence enabled by these technologies to deterministic content delivery over 5G optical transport networks. | Yuefeng Ji Jiawei Zhang Yuming Xiao Zhen Liu | 2019 | China Communications2019,16,5: | 9 |
| 6 | Photonic integrated technology for multi-wavelength laser emission显示文摘We summarized the design, fabrication challenges and important technologies for multi-wavelength laser transmitting photonic integration. Technologies discussed include multi-wavelength laser arrays, monolithic integration and modularizing coupling and packaging. Fabrication technique requirements have significantly declined with the rise of reconstruction-equivalent-chirp and second nanoimprint mask technologies. The monolithic integration problem between active and passive waveguides can be overcome with Butt-joint and InP array waveguide grating technologies. The dynamic characteristics of multi-factors will be simultaneously measured with multi-port analyzing modules. The performance of photonic integration chips is significantly improved with the autoecious factors compensation packaging technique. | CHEN XiangFei LIU Wen AN JunMing LIU Yu XU Kun WANG Xin LIU JianGuo JI YueFeng ZHU NingHua | 2011 | Chinese Science Bulletin2011,56,28: | 9 |
| 7 | Quantitative features of myoelectric signals in the orbicularis oculi muscle during different motion states显示文摘Artificial facial nerve prostheses are thought to restore eye-closed function in peripheral facial paralysis patients. At present,however,there is no adequate quantitative or qualitative information regarding myoelectric signal(MES) features for healthy orbicularis oculi muscle(OOM) . The present study analyzed MES features of normal OOM in rabbits during the natural continuous eye-opening(N1) state,natural continuous eye-closing(N2) state,natural blink(N3) state,and evoked eye-closing(E) state according to time domain and frequency domain analysis. Results showed that OOM electrical activities in N1 and N2 states,as well as myoelectric amplitude,were low and stable. Nevertheless,during N3 and E states,OOM electrical activities were significantly increased and amplitude was much higher in the E state than in the N3 state. In the time domain,differences in MES peak absolute potential were not significant between N1 and N2 states. In the frequency domain,differences in power spectral density peak frequency of electromyogram signals were significant between two sets of four OOM movement states. These results suggest that OOM significantly contracts and induces eyelid-closing action. In addition,OOM is diastolic during the N1 state. A N2 state does not require continuous intensive OOM contraction. Moreover,distinctions of quantitative information in time and frequency domain features of MES can be used as an OOM reference to identify muscle movement patterns. | Dongyue Xu Keyong Li Jingquan Liu Yujuan Wang Yuefeng Rui | 2010 | Neural Regeneration Research2010,5,24: | 6 |

| 9 | Effects of capture and captivity on plasma corticosterone and metabolite levels in breeding Eurasian Tree Sparrows显示文摘Background: Bringing free-living animals into captivity subjects them to the stress of both capture and captivity, leading to the alteration of normal physiological processes and behaviors through activation of the hypothalamic– pituitary–adrenal axis. In free-living birds, although elevated plasma corticosterone (CORT) is an important adaptation regulating physiological and behavioral responses during the process of capture and captivity stress, little information is currently available on the effects of such stress on plasma metabolite levels. Methods: We examined the effects of immediate capture and 24-h captivity on body mass, body condition, plasma CORT, and metabolite levels including glucose (Glu), triglyceride (TG), total cholesterol (TC), uric acid (UA), in breeding Eurasian Tree Sparrows (Passer montanus). Results: CORT and Glu levels were increased significantly by the stress of capture, whereas TC and UA levels decreased. Body mass, body condition declined notably after 24 h in captivity, but CORT, Glu, and UA levels increased. Furthermore, male sparrows had lower TG levels after both capture and captivity than those of females. The relationships between plasma CORT and metabolite levels varied between sexes. Conclusions: Our results revealed that the metabolic status of Eurasian Tree Sparrows could be dramatically altered by capture and captivity. Monitoring the dynamic effects of both capture and captivity on plasma CORT, metabolite levels in a free-living bird contributes to a better understanding of the stress-induced pathways involved in sexdependent energy mobilization. | Mo Li Weiwei Zhu Yang Wang Yanfeng Sun Juyong Li Xuelu Liu Yuefeng Wu Xuebin Gao Dongming Li | 2019 | Avian Research2019,10,2: | 5 |
| 10 | Effect of Sini San Freeze-dried powder on sleep-waking cycle in insomnia rats显示文摘OBJECTIVE: To investigate the effects of the Sini San at different doses on each sleeping state[slow-wave sleep 1(SWS1), slow-wave sleep 2(SWS2), rapid-eye-movement(REM), wakefulness(W)] in insomnia rats and to identify its mode of ac-tion for improving sleep.METHODS: The insomnia rats were randomly divided into a high-, medium- or low-dose group of Sini San(equal to crude drug 8.8, 4.4, or 2.2 g/kg, respectively) for seven consecutive days.RESULTS: Compared with pre-administration,SWS2 was significantly increased after administration of the low dose. Compared with pre-administration, W was significantly decreased and SWS1,SWS2, and the total sleeping time(TST) were markedly increased after administration of the medium dose. Compared with pre-administration, W was significantly decreased and SWS1, SWS2, rapid-eye-movement sleep, and TST were significantly longer after administration of the high dose. The effects of Sini San on sleep-wake cycle are dose-dependent.CONCLUSION: The results suggest that Sini San extends SWS1 and SWS2, which increases the total sleeping time. | Xingke Yan Zeguo Zhang Fuju Xu Yuefeng Li Tiantian Zhu Chongbing Ma Anguo Liu | 2014 | Journal of Traditional Chinese Medicine2014,34,5: | 4 |
| 11 | Oxidative dehydrogenation of propane over Ni-Mo-Mg-O catalysts显示文摘In this work, a series of Ni-Mo-Mg-O catalysts with mesoporous structure prepared by sol-gel method were investigated for the oxidative dehydrogenation of propane (ODHP). The techniques of temperature-programmed reduction with H2 (H2-TPR), N2 adsorption-desorption, Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) and X-ray photoelectron spectra (XPS) were employed for catalyst characterization. It is found that the activity of the catalysts for ODHP increases first and then decreases with the increase of Mo content. The catalyst with a Mo/Ni atomic ratio of 1/1 exhibits the best catalytic activity, which gives the propene selectivity of 81.4% at a propane conversion of 11.3% under 600°C and maintains the good catalytic performance for 22 h on stream. This is related not only to its high reducibility and dispersion as revealed by TPR and XRD, but also to the formation of more selective oxygen species on the MoOx-NiO interface as identified by XPS. | Lin Wang Wei Chu Chengfa Jiang Yuefeng Liu Jie Wen Zaiku Xie | 2012 | Journal of Natural Gas Chemistry2012,21,1: | 4 |
| 12 | Improving the performance of solid oxide electrolysis cell with gold nanoparticles-modified LSM-YSZ anode显示文摘Gold, as the common current collector in solid oxide electrolysis cell(SOEC), is traditionally considered to be inert for oxygen evolution reaction at the anode of SOEC. Herein, gold nanoparticles were loaded onto conventional strontium doped lanthanum manganite-yttria stabilized zirconia(LSM-YSZ) anode, which evidently improved the performance of oxygen evolution reaction at 800 °C. The current densities at 1.2 V and 1.4 V increased by 60.0% and 46.9%, respectively, after loading gold nanoparticles onto the LSM-YSZ anode. Physicochemical characterizations and electrochemical measurements suggested that the improved SOEC performance was attributed to the accelerated electron transfer of elementary process in anodic polarization reaction and the newly generated triple phase boundaries in gold nanoparticles-loaded LSMYSZ anode. | Yuefeng Song Xiaomin Zhang Yingjie Zhou Houfu Lv Qingxue Liu Weicheng Feng Guoxiong Wang Xinhe Bao | 2019 | Journal of Energy Chemistry2019,28,8: | 4 |
| 13 | Analysis and experimentation of key technologies in service-oriented optical internet显示文摘To satisfy diverse bandwidth-intensive applications envisioned in the internet of the future, research on a distributed optical internet, enabling efficient utilization of geographically distributed resources, has become attractive. The deployment of such a network, however, has its own technical challenges, including network architecture, resource management, and high-speed transmission. To address these issues, a service-oriented-architecture-based distributed optical internet architecture is proposed. Thereafter, key technologies of an optical internet, such as optical multicasting, distributed resource control, and high-speed transmission, are analyzed and investigated. The proposed schemes are verified through experimentation and simulation. | JI YueFeng REN DanPing LI Hui LIU XueJun WANG ZhengZhong | 2011 | Science China(Information Sciences)2011,54,2: | 3 |
| 14 | Infiltration of Ce0.8Gd0.2O1.9 nanoparticles on Sr2Fe1.5Mo0.5O6-δ cathode for CO2 electroreduction in solid oxide electrolysis cell显示文摘Solid oxide electrolysis cell(SOEC) can electrochemically convert CO2 to CO at the gas-solid interface with a high current density and Faradaic efficiency, which has attracted increasing attentions in recent years.Exploring efficient catalyst for electrochemical CO2 reduction reaction(CO2 RR) at the cathode is a grand challenge for the research and development of SOEC. Sr2Fe1.5Mo0.5O6-δ(SFM) is one kind of promising cathode materials for SOEC, but suffers from insufficient activity for CO2 RR. Herein, Gd0.2Ce0.8O1.9(GDC)nanoparticles were infiltrated onto the SFM surface to construct a composite GDC-SFM cathode and improve the CO2 RR performance in SOEC. The current density over the GDC infiltrated SFM cathode with a GDC loading of 12.8 wt% reaches 0.446 A cm-2 at 1.6 V and 800 °C, which is much higher than that over the SFM cathode(0.283 A cm-2). Temperature-programmed desorption of CO2 measurements suggest that the infiltration of GDC nanoparticles significantly increases the density of surface active sites and three phase boundaries(TPBs), which are beneficial for CO2 adsorption and subsequent conversion. Electrochemical impedance spectroscopy results indicate that the polarization resistance of 12.8 wt% GDCSFM cathode was obviously decreased from 0.46 to 0.30 cm^2 after the infiltration of GDC nanoparticles. | Houfu Lv Yingjie Zhou Xiaomin Zhang Yuefeng Song Qingxue Liu Guoxiong Wang Xinhe Bao | 2019 | Journal of Energy Chemistry2019,28,8: | 3 |
| 15 | Molybdenum carbide clusters for thermal conversion of CO2 to CO via reverse water-gas shift reaction显示文摘Molybdenum carbides are highly active for CO2 conversion to CO via the reverse water-gas shift(RWGS)reaction, however the large grain size up to micrometers renders its relatively lower active sites utilization efficiency while generating CH4 as a by-product. In this work, a homogeneously dispersed molybdenum carbide hybrid catalyst with sub-nanosized cluster(the average size as small as 0.5 nm) is prepared via a facile carbothermal treatment for highly selective CO2-CO reduction. The partially disordered Mo2C clusters are characterized by synchrotron high-resolution XRD and atomic resolution HAADF-STEM analysis, for which the source cause of the disorder is pinpointed by XAFS analysis to be the nitrogen intercalants from the carbonaceous precursor. The partially disordered Mo2C clusters show a RWGS rate as high as 184.4 μmol gMo2C-1s-1 at 400 ℃ with a superior selectivity toward CO(> 99.5%). This work 2 highlights a facile strategy for fabricating highly dispersed and partially disordered Mo2C clusters at a sub-nano size with beneficial N-doping for delivering high catalytic activity and operational stability. | Ying Ma Zhanglong Guo Qian Jiang Kuang-Hsu Wu Huimin Gong Yuefeng Liu | 2020 | Journal of Energy Chemistry2020,29,11: | 3 |
| 16 | Using loose nanofiltration membrane for lake water treatment:A pilot study显示文摘Nanofiltration(NF)using loose membranes has a high application potential for advanced treatment of drinking water by selectively removing contaminants from the water,while membrane fouling remains one of the biggest problems of the process.This paper reported a seven-month pilot study of using a loose NF membrane to treat a sand filtration effluent which had a relatively high turbidity(∼0.4 NTU)and high concentrations of organic matter(up to 5 mg/L as TOC),hardness and sulfate.Results showed that the membrane demonstrated a high rejection of TOC(by<90%)and a moderately high rejection of two pesticides(54%–82%)while a moderate rejection of both calcium and magnesium(∼45%)and a low rejection of total dissolved solids(∼27%).The membrane elements suffered from severe membrane fouling,with the membrane permeance decreased by 70%after 85 days operation.The membrane fouling was dominated by organic fouling,while biological fouling was moderate.Inorganic fouling was mainly caused by deposition of aluminum-bearing substances.Though inorganic foulants were minor contents on membrane,their contribution to overall membrane fouling was substantial.Membrane fouling was not uniform on membrane.While contents of organic and inorganic foulants were the highest at the inlet and outlet region,respectively,the severity of membrane fouling increased from the inlet to the outlet region of membrane element with a difference higher than 30%.While alkaline cleaning was not effective in removing the membrane foulants,the use of ethylenediamine tetraacetate(EDTA)at alkaline conditions could effectively restore the membrane permeance. | Danyang Liu Johny Cabrera Lijuan Zhong Wenjing Wang Dingyuan Duan Xiaomao Wang Shuming Liu Yuefeng F.Xie | 2021 | Frontiers of Environmental Science & Engineering2021,15,4: | 3 |
| 17 | Artificial facial nerve reflex restores eyelid closure following orbicularis oculi muscle denervation显示文摘To date,treatment of peripheral facial paralysis has focused on preservation of facial nerve integrity.However,with seriously damaged facial nerve cases,it is difficult to recover anatomical and functional integrity using present therapies.Therefore,the present study utilized artificial facial nerve reflex to obtain orbicularis oculi muscle(OOM) electromyography signals on the uninjured side through the use of implanted recording electrodes.The implanted electrical chips analyzed facial muscle motion on the uninjured side and triggered an electrical stimulator to emit current pulses,which resulted in stimulation of injured OOM contraction and maintained bilateral symmetry and consistency.Following signal recognition,extraction,and computer analysis,electromyography signals in the uninjured OOM resulted in complete eyelid closure,which was consistent with the voltage threshold for eye closure.These findings suggested that artificial facial nerve reflex through the use of implanted microelectronics in unilateral peripheral facial paralysis could restore eyelid closure following orbicularis oculi muscle denervation. | Yujuan Wang Keyong Li Jingquan Liu Dongyue Xu Yuefeng Rui Chunsheng Yang | 2010 | Neural Regeneration Research2010,5,22: | 3 |
| 18 | The inhibitory effects of siRNA expression vector on CXCR4 expression in prostate carcinoma cell lines显示文摘Objective: To investigate the inhibitory effects of RNAi (RNA interference, RNAi) expression vector on CXCR4 expression in prostate carcinoma cell lines. Methods: Small interference RNA(siRNA) expression vectors for CXCR4 gene were constructed and transfected into prostate carcinoma cell lines(PC-3m and LNCaP)with liposomes. The expression of CXCR4 was detected by RT-PCR and western blot. Results: The expression of CXCR4 mRNA and protein in the PC-3m and LNCaP cells was reduced by RNAi expression vectors. The inhibitory rate of CXCR4 mRNA expression in the PC-3m cells was 87.81%±10.20%,56.10%±9.32% at the 24th hour and the 48th hour, compared with 56.93%±8.78%,49.24%±11.23% in LNCaP cells. The inhibitory rate of the expression of CXCR4 protein was 64.71%±6.68%,58.66%±11.56% respectively. Conclusion: The expression of CXCR4 gene can effectively be inhibited by RNAi expression vectors. | Yuefeng Du Yifei Xing Fuqing Zeng Peng Lu Xianyin Liu | 2006 | Journal of Nanjing Medical University2006,20,2: | 3 |
