| 1 | Kinetics of Solvent Blue and Reactive Yellow removal using microwave radiation in combination with nanoscale zero-valent iron显示文摘We investigated the efficiency and kinetics of the degradation of soluble dyes over the p H range 5.0–9.0 using a method employing microwave radiation in combination with nanoscale zero-valent iron(MW–n ZVI). The n ZVI particles(40–70 nm in diameter) were prepared by a liquid-phase chemical reduction method employing starch as a dispersant.Compared to the removal of Solvent Blue 36 and Reactive Yellow K-RN using only n ZVI,more rapid and efficient dye removal and total organic carbon removal were achieved using MW–n ZVI. The dye removal efficiency increased significantly with decreasing p H, but was negligibly affected by variation in the microwave power. The kinetics of dye removal by MW–n ZVI followed both an empirical equation and the pseudo first-order model, while the kinetics of dye removal using n ZVI could only be described by an empirical equation. It was also concluded that microwave heating of the dye solutions as well as acceleration of corrosion of n ZVI and consumption of Fe(II) were possible reasons behind the enhanced dye degradation. | Yanpeng Mao Zhenqian Xi Wenlong Wang Chunyuan Ma Qinyan Yue | 2015 | Journal of Environmental Sciences2015,27,4: | 3 |
| 2 | Non-Hermitian control of confined optical skyrmions in microcavities formed by photonic spin-orbit coupling显示文摘Optical skyrmions formed by photonic spin–orbit(SO)coupling are of significant interest in high-dimensional optical information processing.We report the formation mechanism and non-Hermitian properties of skyrmionlike states in a circular confinement potential with photonic SO coupling,which is preferably realized in a concave-planar microcavity system.We show that the effective photonic gauge field leads to two split manifolds of degenerate skyrmions whose spin textures can be controlled via the non-Hermitian properties by introducing circularly polarized gain and loss,exhibiting dramatically discrepant evolutions at the two sides of the exceptional point(EP).Furthermore,the lifetime degeneracy can be lifted by spatially inhomogeneous pumping according to the non-Hermitian mechanism,enabling the possibility for the skyrmion laser.By introducing shape asymmetry of the confinement potential,a double EP evolution can be achieved,which allows non-Hermitian control of the SO coupled states with higher degrees of freedom.These results open the way for the non-Hermitian control of photonic spin in confined systems,which would be of great significance for the fundamentals of advanced optical information processing. | XIAOXUAN LUO YIN CAI XIN YUE WEI LIN JINGPING ZHU YANPENG ZHANG FENG LI | 2023 | Photonics Research2023,11,4: | 1 |
| 3 | All five COVID-19 outbreaks during epidemic period of 2020/2021 in China were instigated by asymptomatic or pre-symptomatic individuals显示文摘Introduction:The significance of asymptomatic or pre-asymptomatic individuals in driving the COVID-19 epidemic in China or other countries remains uncertain.Method:We collected and analyzed all the epidemiologic and virological diagnostic details of the infected individuals released by public health authorities and reiterated every episode of outbreak on a timeline.All individuals associated with the five outbreaks had tested positive for SARS-CoV-2 infection.Results:In this study,all five COVID-19 outbreaks reported in China since October 2020 were analyzed.The Kashgar outbreak in Xinjiang province came into light for the first time on October 22,2020.However,it was initiated before October 11,2020,by a local asymptomatic import and export worker,who was infected at the working place.Subsequently,his wife caught the infection,which led to 430 more infections reported in the outbreak.The Beijing outbreak with 41 cases was noticed for the first time on December 22,2020.However,our analysis revealed that it was initiated by an asymptomatic individual from Indonesia on December 10,2020.The Shenyang outbreak,with 38 cases,noticed for the first time on December 23,2020,was initiated by a pre-symptomatic individual from South Korea on December 13,2020.Conclusion:The asymptomatic or pre-symptomatic individuals during the asymptomatic period were unsuspectingly infected by SARS-CoV-2,and unintentionally transmitted the virus to a large number of people.These findings suggest that early detection of asymptomatic or pre-symptomatic individuals is of critical importance in preventing future outbreaks or epidemics. | Caixin Yang Sihui Zhang Shan Lu Jing Yang Yanpeng Cheng Yue Liu Lijun Zhao Jian Gong Jianguo Xu | 2021 | Journal of Biosafety and Biosecurity2021,3,1: | 1 |
| 4 | Mass Transfer, Gas Holdup, and Kinetic Models of Batch and Continuous Fermentation in a Novel Rectangular Dynamic Membrane Airlift Bioreactor显示文摘Compared with conventional cylinder airlift bioreactors(CCABs)that produce coarse bubbles,a novel rectangular dynamic membrane airlift bioreactor(RDMAB)developed in our lab produces fine bubbles to enhance the volumetric oxygen mass transfer coefficient(k_(L)a)and gas holdup,as well as improve the bioprocess in a bioreactor.In this study,we compared mass transfer,gas holdup,and batch and con-tinuous fermentation for RNA production in CCAB and RDMAB.In addition,unstructured kinetic models for microbial growth,substrate utilization,and RNA formation were established.In batch fermentation,biomass,RNA yield,and substrate utilization in the RDMAB were higher than those in the CCAB,which indicates that dynamic membrane aeration produced a high k_(L)a by fine bubbles;a higher k_(L)a is more bene-ficial to aerobic fermentation.The starting time of continuous fermentation in the RDMAB was 20 h ear-lier than that in the CCAB,which greatly improved the biological process.During continuous fermentation,maintaining the same dissolved oxygen level and a constant dilution rate,the biomass accumulation and RNA concentration in the RDMAB were 9.71% and 11.15% higher than those in the CCAB,respectively.Finally,the dilution rate of RDMAB was 16.7% higher than that of CCAB during con-tinuous fermentation while maintaining the same air aeration.In summary,RDMAB is more suitable for continuous fermentation processes.Developing new aeration and structural geometry in airlift bioreac-tors to enhance k_(L)a and gas holdup is becoming increasingly important to improve bioprocesses in a bioreactor. | Ganlu Li Kequan Chen Yanpeng Wei Jinlei Zeng Yue Yang Feng He Hui Li Pingkai Ouyang | 2022 | Engineering2022,8,6: | 1 |

| 7 | Exploring the salt-and drought-tolerant genes of alfalfa through expression library screening strategy显示文摘Salinity and drought stress are major abiotic stresses negatively affecting the growth and productivity of alfalfa(Medicago sativa L.).Exploration of genes exhibiting superior tolerance to salinity and drought stress in alfalfa will help aid target molecular breeding and developing tolerant forages.In this study,we adopted a high-efficient yeast FOX hunting system for the identification of salinity and drought tolerant genes in alfalfa.Based on the Gateway-compatible vector system,a high-quality expression library was constructed,containing 1.3×10^(7) clones with an average size of 1.44 kb.Through heterologous transformation of mixed library plasmid into salt or drought sensitive yeast mutants,monoclonal resistant strains were screened and tolerant genes were captured.Eighteen salinity-tolerance genes were obtained which were involved in several pathways,containing GRAS and zinc finger transcriptional factors,PP2A interaction module,ERVT vesicle transporter and LETM transmembrane protein.Twelve drought tolerance genes were separated,including ERF and SCL transcriptional factors,CIPK and BSK protein kinases,TGL-type ligase,cPGM and cPDL protease.The mRNA transcription levels of these tolerant genes were inducible or suppressible for response to salt or drought stress conditions following quantitative PCR detection,respectively.Furthermore,heterologous transformation of ERVT and CIPK11 can improve the salt and drought stress tolerance in Arabidopsis,which indicates the conservative function of the screening gene in yeast and Arabidopsis.Obtaining these candidate genes can provide new insights for future research with respect to plant salt and drought tolerance. | Zhihua Li Yue Zou Yanpeng Li Cancan Sun Yu Liu Liwen Cui Jun Liu Zhimin Yang Yu Chen | 2021 | Grass Research2021,1,1: | 0 |
| 8 | Theoretical study on dynamic effective electroelastic properties of random piezoelectric composites with aligned inhomogeneities显示文摘The closed-form solutions of the dynamic problem of heterogeneous piezoelectric materials are formulated by introducing polarizations into a reference medium and using the generalized reciprocity theorem.These solutions can be reduced to the ones of an elastodynamic problem.Based on the effective medium method,these closedform solutions can be used to establish the self-consistent equations about the frequencydependent effective parameters,which can be numerically solved by iteration.Theoretical predictions are compared with the experimental results,and good agreement can be found.Furthermore,the analyses on the effects of microstructure and wavelength on the effective properties,resonance frequencies,and attenuation are also presented,which may provide some guidance for the microstructure design and analysis of piezoelectric composites. | Yanpeng YUE Yongping WAN | 2023 | Applied Mathematics and Mechanics(English Edition)2023,44,4: | 0 |
| 9 | Experimental study on ice monitoring method for 10 kV transmission line with tangent tower in alpine landform显示文摘Ice monitoring methods were applied for 110 kV and above transmission lines with tangent towers.However,the change in the vertical span is not considered,and a significant difference lies in the tower-conductor structure of 10 kV transmission lines.For this reason,a proposal is made about the ice monitoring method for the 10 kV transmission line with tangent tower in alpine landform,which includes the ice monitoring system based on pressure measurement and corresponding equivalent ice thickness calculating methods.Different methods calculate the vertical span under different height difference coefficients.A finite element simulation model and a simulated ice load experiment system are established based on real conductors and insulators.Experiments and simulations under four simulated terrains are conducted within 2.5–20 mm ice thickness range.The comparison is made between this method and the method without considering the change in vertical span.The results show that the two methods are consistent and the relative errors are lower than�4%in simulation and�10%in experiment when the height difference coefficient is 0.When it is not 0,the relative errors of this method fall between t0.38%and t6.78%in simulation and−6.40%to t6.60%in experiment,while the relative errors of the method without considering the change in vertical span ranges between−11.13%and−20.23%in simulation and−11.65%to−23.20%in experiment. | Lin Yang Zhiqiang Chen Yanpeng Hao Xinhao Lin Lei Yu Yue Li Zhiyong Yuan Licheng Li | 2024 | High Voltage2024,9,1: | 0 |
| 10 | LSM12 facilitates the progression of colorectal cancer by activating the WNT/CTNNB1 signaling pathway显示文摘Aberrant activation of the WNT signaling pathway is a joint event in colorectal cancer(CRC),but the molecular mechanism is still unclear.Recently,RNA-splicing factor LSM12(like-Sm protein 12)is highly expressed in CRC tissues.This study aimed to verify whether LSM12 is involved in regulating CRC progression via regulating the WNT signaling pathway.Here,we found that LSM12 is highly expressed in CRC patient-derived tissues and cells.LSM12 is involved in the proliferation,invasion,and apoptosis of CRC cells,similar to the function of WNT signaling in CRC.Furthermore,protein interaction simulation and biochemical experiments proved that LSM12 directly binds to CTNNB1(also known asβ-Catenin)and regulates its protein stability to affect the CTTNB1-LEF1-TCF1 transcriptional complex formation and the associated WNT downstream signaling pathway.LSM12 depletion in CRC cells decreased the in vivo tumor growth through repression of cancer cell growth and acceleration of cancer cell apoptosis.Taken together,we suggest that the high expression of LSM12 is a novel factor leading to aberrant WNT signaling activation,and that strategies targeting this molecular mechanism may contribute to developing a new therapeutic method for CRC. | YAN ZHUANG CHUNLAN NING PENGFEI LIU YANPENG ZHAO YUE LI ZHENCHI MA LULING SHAN YINGZHE PIAO PENG ZHAO XUN JIN | 2022 | Oncology Research2022,30,6: | 0 |
| 11 | Bioinspired Multifunctional Self-Sensing Actuated Gradient Hydrogel for Soft-Hard Robot Remote Interaction显示文摘The development of bioinspired gradient hydrogels with self-sensing actuated capabilities for remote interaction with soft-hard robots remains a challenging endeavor. Here, we propose a novel multifunctional self-sensing actuated gradient hydrogel that combines ultrafast actuation and high sensitivity for remote interaction with robotic hand. The gradient network structure, achieved through a wettability difference method involving the rapid precipitation of MoO_(2) nanosheets, introduces hydrophilic disparities between two sides within hydrogel. This distinctive approach bestows the hydrogel with ultrafast thermo-responsive actuation(21° s^(-1)) and enhanced photothermal efficiency(increase by 3.7 ℃ s^(-1) under 808 nm near-infrared). Moreover, the local cross-linking of sodium alginate with Ca^(2+) endows the hydrogel with programmable deformability and information display capabilities. Additionally, the hydrogel exhibits high sensitivity(gauge factor 3.94 within a wide strain range of 600%), fast response times(140 ms) and good cycling stability. Leveraging these exceptional properties, we incorporate the hydrogel into various soft actuators, including soft gripper, artificial iris, and bioinspired jellyfish, as well as wearable electronics capable of precise human motion and physiological signal detection. Furthermore, through the synergistic combination of remarkable actuation and sensitivity, we realize a self-sensing touch bioinspired tongue. Notably, by employing quantitative analysis of actuation-sensing, we realize remote interaction between soft-hard robot via the Internet of Things. The multifunctional self-sensing actuated gradient hydrogel presented in this study provides a new insight for advanced somatosensory materials, self-feedback intelligent soft robots and human–machine interactions. | He Liu Haoxiang Chu Hailiang Yuan Deliang Li Weisi Deng Zhiwei Fu Ruonan Liu Yiying Liu Yixuan Han Yanpeng Wang Yue Zhao Xiaoyu Cui Ye Tian | 2024 | Nano-Micro Letters2024,16,4: | 0 |
