| 1 | Rational design of phosphorus-doped cobalt sulfides electrocatalysts for hydrogen evolution显示文摘Moderate anionic doping is an effective approach to improve the performance of electrocatalysts toward hydrogen evolution reaction(HER)since it can adjust the electronic structure,activesite,and phase.The reported studies mainly focus on designing P doped C0S2,while otherphases of cobalt sulfide,such as Co1-xS and Co9S8 doped with P are rarely investigated for HER electrocatalysts.Herein,various cobalt sulfides(including CoSg/Co1-xS,Co1-xS,and Co9S8)doped with P are anchored on carbon cloth through a facile hydrothermal method.Among tested electrocatalysts,P doped Co1-xS exhibits excellent electrocatalytic performance with an overpotential of 110 and 165 mV(vs.RHE)for currentdensities of 10 and 100 mA·cm^-2,respectively.Density functional theory calculations reveal that P doped Co1-xS possesses a smaller bandgapand more optimal hydrogen adsorption sites than pristine Co1-xS.This work initially investigates various cobalt sulfides doped with P and furthergets in sight into the activity improvement mechanism of P dopi ng,which could guide the desig n of earth-abunda nt HER electrocatalysts for the'hydrogen economy'. | Guoxing Qu Tianli Wu Yanan Yu Zekang Wang Yang Zhou Zhendong Tang Qin Yue | 2019 | Nano Research2019,12,12: | 5 |
| 2 | High wave transmittance and low thermal conductivity Y-a-SiAlON porous ceramics for high-temperature radome applications显示文摘With the development of hypersonic vehicle technology,ceramic-based radome materials are highly demanded due to their high operating temperatures,good dielectric properties,and high mechanical properties.Althoughα-SiAlON is an ideal material for radome applications,its intrinsic low transmittance and high thermal conductivity limit its applications.Herein,we prepared Y-α-SiAlON porous ceramics through tert-butanol(TBA)gel-casting using the self-synthesizedα-SiAlON powder.The Y-α-SiAlON porous ceramics exhibited a uniform micron-level connected pore structure with the porosity(P)of 44.2%-58.6%.The real part of permittivity(s')was 3.13-4.18(8.2-12.4 GHz),which decreased significantly with the increasing porosity.The wave transmittance(|T|^(2))of the sample with porosity of 58.6%could exceed 80%in the thickness range of 6-10 mm.The thermal conductivity was maintained at a low level of 1.38-2.25 W·m^(-1)·K^(-1) owing to the introduction of the pore structure.The flexural strength was 44.73-88.33 MPa,which may be increased by rod-likeα-SiAlON grains.The results indicate that the prepared Y-α-SiAlON porous ceramics meet the requirements of high-temperature wave-transmitting materials for radome applications. | Runwu Yang Jie Xu Jia Guo Xuanyu Meng Ping Zhang Fengying Fan Yanan Qu Feng Gao | 2023 | Journal of Advanced Ceramics2023,12,6: | 1 |
| 3 | Grain boundary character and stress corrosion cracking behavior of Co-Cr alloy fabricated by selective laser melting显示文摘In this work,we used the selective laser melting(SLM)fabricated Co-Cr alloy with prominent residual strain,extremely non-equilibrium microstructures,and low stacking fault energy as a precursor to fabricate materials with the optimal grain boundary character distribution.The grain boundary engineering(GBE)of the Co-Cr alloy was achieved by a simple heat treatment of the SLM-fabricated Co-Cr alloy.The obtained GBE Co-Cr alloy exhibited 81.47%of special grain boundaries(∑3^(n)n=1,2,3),while it substantially disrupted the connectivity of the random high-angle boundaries,successfully reducing the propensity of intergranular degradation.Slow strain rate tests(SSRTs)showed that the GBE Co-Cr alloy possessed lower stress corrosion cracking(SCC)susceptibility and higher ductility in the corrosive environment(0.9%Na Cl solution)than in the air.The high fraction of special boundaries,coupled with the stress-induced martensitic transformation(SIMT)in the GBE Co-Cr alloy yielded these results,which unique and rarely simultaneously satisfied for common structural materials.The current'SLM induced GBE strategy'offers a novel approach towards customized GBE materials with high SCC resistance and ductility in the corrosive environment,shedding new light on developing high-performance structural materials. | Xin Dong Ning Li Yanan Zhou Huabei Peng Yuntao Qu Qi Sun Haojiang Shi Rui Li Sheng Xu Jiazhen Yan | 2021 | Journal of Materials Science & Technology2021,,34: | 1 |
| 4 | Shaking table test of subgrade slope reinforced by gravity retaining wall with geogrids显示文摘Gravity retaining wall with geogrids has showed excellent seismic performance from Wenchuan great earthquake.However,seismic damage mechanism of this kind of wall is not sufficiently clear.In view of this,a large shaking table test of the gravity retaining wall with geogrids to reinforce the subgrade slope was carried out,and based on the HilbertHuang transform and the marginal spectrum theory,the energy identification method of the slope dynamic failure mode was studied.The results show that the geogrids can effectively reduce displacement and rotation of the retaining wall,and it can effectively absorb the energy of the ground movement when combined with the surrounding soil.In addition,it also reveals the failure development of the gravity retaining wall with geogrids to reinforce the subgrade slope.The damage started in the deep zone near the geogrids,and then gradually extended to the surface of the subgrade slope and other zones,finally formed a continuous failure surface along the geogrids.The analysis results of the failure mode identified by the Hilbert marginal spectrum are in good consistency with the experimental results,which prove that the Hilbert marginal spectrum can be applied to obtain the seismic damage mechanism of slope. | Qu Honglue Huang Xue Gao Yanan Zhang Zhe Wang Chenxu | 2022 | Earthquake Engineering and Engineering Vibration2022,21,3: | 1 |

| 6 | Study on the Use of Force Measures in Maritime Law Enforcement by China Coast Guard显示文摘In recent years,China’s fishing boats have been repeatedly attacked by the armed forces of other countries’maritime law enforcement forces.Whether the use of these armed measures conforms to the provisions of international law deserves our deep thinking.Since the establishment of China Coast Guard Bureau,as the main force of maritime law enforcement,according to the relevant provisions of domestic law and international law,it is possible to use force measures reasonably when it is necessary.However,the current regulations on the use of maritime enforcement of force measures in China are still not perfect and still need to be further clear in the law. | QU Yanan | 2019 | US-China Law Review2019,16,5: | 0 |
| 7 | One-step synthesis of hierarchical Ni_(3)Se_(2)nanosheet-on-nanorods/Ni foam electrodes for hybrid supercapacitors显示文摘Transitional metal selenides have high conductivity,even metal quality,which makes them great for using as electrode materials for fabricating supercapacitors.Here,hierarchical Ni_(3)Se_(2)nanosheet-on-nanorods on Ni foam(NSR-Ni_(3)Se_(2)/Ni)was fabricated by a facile three-dimensional(3D)substrate-assisted confinement assembly method,and used as a freestanding electrode material for hybrid supercapacitors(HSCs).In this design,metallic Ni_(3)Se_(2)with hybrid 1D/2D architecture could effectively enhance the active specific surface area of electrode and improve space utilization,as well as significantly facilitate electrons transport,while Ni foam served as the Ni source of Ni_(3)Se_(2)and provided 3D multi-electron transport channels,thus boosting the specific capacity.The constructed hierarchical NSR-Ni_(3)Se_(2)electrode delivered a superior areal specific capacity of 1.068 mAh/cm^(2)(7.69 F/cm^(2))at 2 mA/cm^(2)and retained 68.2%of the initial capacity when the current density increases by 15 times.Furthermore,the as-assembled NSR-Ni_(3)Se_(2)device exhibited an ultrahigh energy density of 56.4 Wh/kg and high power density of 4640.3 W/kg,and a capacity retention of 92.6%even after 6000 cycles. | Fangshuai Chen Yanan Chen Qing Han Liangti Qu | 2022 | Chinese Chemical Letters2022,33,1: | 0 |
| 8 | Axially N-Embedded Quasi-Carbon Nanohoops with Multioxidation States显示文摘The incorporation of heteroatoms into carbon nanohoops can significantly overcome aromatic stabilization energy and enrich their physicochemical properties depending on the positions and numbers of the doped atoms.Utilizing a V-shaped dipyreneo[c,e]dihydrophenazine as the building block,herein we report a novel kind of axially N-embedded quasi-carbon nanohoops by integratingπ-extended dihydropyrazine and para-phenylene subunits.Singlecrystal X-ray diffraction analyses revealed that their geometrical structures varied from droplet-shaped geometry for DPP-M and suppressed elliptical cross-section configuration for DPP-D to triangularly prismatic configuration for DPP-T.Spectroscopic measurements confirmed rich electronic properties,especially multioxidation behaviors due to the embedding of graphitic-N atoms,which are not observed in carbonaceous nanohoops and other analogs.Further investigations,including electron spin resonance spectroscopy,theoretical calculations,and single-crystal structure analyses,on the oxidized species of both DPP-D and DPP-T demonstrated their tunable open-shell ground states for the dications.This work provides a new synthetic strategy to axially N-embedded quasi-carbon nanohoops and gives insights into the design of structure-precise segments of graphitic-N-doped single-walled carbon nanotubes. | Shuhai Qiu Yongye Zhao Li Zhang Yong Ni Yanan Wu Huan Cong Da-Hui Qu Wei Jiang Jishan Wu He Tian Zhaohui Wang | 2023 | CCS Chemistry2023,5,8: | 0 |
| 9 | Sensory Evaluation of Hydroxy Ethyl Cellulose (HEC) in Facial Mask显示文摘An equipment test and sensory evaluation were conducted to identify the compatibility and sensory characteristics of HEC in facial masks. These results were then compared to xanthan gum usage. The equipment test results showed that HEC promoted proper tensile capacity in masks which are made from strong structured fabrics such as medium thick, thick and cross woven & homogenous thin mask fabrics. HEC was found to be more compatible with mask fabrics than xanthan gum. HEC improved mask softness and dampness and had an improved water binding and water retention ability compared to xanthan gum. The split face sensory evaluation results demonstrated that sheet masks containing HEC had improved adhesion and lubricity, provided more moisture to the skin, better elasticity and gloss after use and took longer to dry out. Overall, the panel preferred facial masks which contain HEC. | Li Yanan Zhao Xiaomin Qu Xin | 2018 | China Detergent & Cosmetics2018,3,2: | 0 |
| 10 | Translocation of IGF-1R in endoplasmic reticulum enhances SERCA2 activity to trigger Ca_(ER)^(2+)perturbation in hepatocellular carcinoma显示文摘The well-known insulin-like growth factor 1(IGF1)/IGF-1 receptor(IGF-1R)signaling pathway is overexpressed in many tumors,and is thus an attractive target for cancer treatment.However,results have often been disappointing due to crosstalk with other signals.Here,we report that IGF-1R signaling stimulates the growth of hepatocellular carcinoma(HCC)cells through the translocation of IGF-1R into the ER to enhance sarco-endoplasmic reticulum calcium ATPase 2(SERCA2)activity.In response to ligand binding,IGF-1Rβis translocated into the ER byβ-arrestin2(β-arr2).Mass spectrometry analysis identified SERCA2 as a target of ER IGF-1Rβ.SERCA2 activity is heavily dependent on the increase in ER IGF-1Rβlevels.ER IGF-1Rβphosphorylates SERCA2 on Tyr^(990)to enhance its activity.Mutation of SERCA2-Tyr^(990)disrupted the interaction of ER IGF-1Rβwith SERCA2,and therefore ER IGF-1Rβfailed to promote SERCA2 activity.The enhancement of SERCA2 activity triggered Ca_(ER)^(2+)perturbation,leading to an increase in autophagy.Thapsigargin blocked the interaction between SERCA2and ER IGF-1Rβand therefore SERCA2 activity,resulting in inhibition of HCC growth.In conclusion,the translocation of IGF-1R into the ER triggers Ca_(ER)^(2+)perturbation by enhancing SERCA2 activity through phosphorylating Tyr^(990)in HCC. | Yanan Li Keqin Li Ting Pan Qiaobo Xie Yuyao Cheng Xinfeng Wu Rui Xu Xiaohui Liu Li Liu Jiangming Gao Wenmin Yuan Xianjun Qu Shuxiang Cui | 2023 | Acta Pharmaceutica Sinica B2023,13,9: | 0 |
| 11 | Lymphatic vessel:origin,heterogeneity,biological functions,and therapeutic targets显示文摘Lymphatic vessels,comprising the secondary circulatory system in human body,play a multifaceted role in maintaining homeostasis among various tissues and organs.They are tasked with a serious of responsibilities,including the regulation of lymph absorption and transport,the orchestration of immune surveillance and responses.Lymphatic vessel development undergoes a series of sophisticated regulatory signaling pathways governing heterogeneous-origin cell populations stepwise to assemble into the highly specialized lymphatic vessel networks.Lymphangiogenesis,as defined by new lymphatic vessels sprouting from preexisting lymphatic vessels/embryonic veins,is the main developmental mechanism underlying the formation and expansion of lymphatic vessel networks in an embryo.However,abnormal lymphangiogenesis could be observed in many pathological conditions and has a close relationship with the development and progression of various diseases.Mechanistic studies have revealed a set of lymphangiogenic factors and cascades that may serve as the potential targets for regulating abnormal lymphangiogenesis,to further modulate the progression of diseases.Actually,an increasing number of clinical trials have demonstrated the promising interventions and showed the feasibility of currently available treatments for future clinical translation.Targeting lymphangiogenic promoters or inhibitors not only directly regulates abnormal lymphangiogenesis,but improves the efficacy of diverse treatments.In conclusion,we present a comprehensive overview of lymphatic vessel development and physiological functions,and describe the critical involvement of abnormal lymphangiogenesis in multiple diseases.Moreover,we summarize the targeting therapeutic values of abnormal lymphangiogenesis,providing novel perspectives for treatment strategy of multiple human diseases. | Zhaoliang Hu Xushi Zhao Zhonghua Wu Bicheng Qu Minxian Yuan Yanan Xing Yongxi Song Zhenning Wang | 2024 | Signal Transduction and Targeted Therapy2024,9,2: | 0 |
| 12 | Comparative acetylome analysis reveals the potential mechanism of high fat diet function in allergic disease显示文摘Modern technological lifestyles promote allergic diseases,especially food allergies.The underlying molecular mechanisms remain to be uncovered.Protein acetylation is one of the most important post-translational modifications,and it is involved in regulating multiple body metabolic processes.This study aimed to clarify the effects of a high-fat diet(HFD)on allergy risk and the underlying mechanisms.Four-week-old male C57 BL/6 J mice were randomly divided into two groups and fed a normal fat diet(NFD)or HFD for 24 weeks.Then,serum lipids were measured,and skeletal muscle was collected for acetylome analysis.Compared with the findings in the NFD group,HFD-fed mice were obese and hyperlipidemic.Acetylome analysis also revealed 32 differentially expressed proteins between the HFD and NFD groups.Among these,eight acetylated proteins were upregulated in the HFD group.In addition,13 and 11 proteins were acetylated only in the HFD group and NFD group,respectively.These proteins were mainly involved in regulating energy metabolism and mitochondrial function.This study provides information regarding the underlying molecular mechanisms by which HFD promotes allergy. | Yanan Sun Ning Liu Huihui Wang Taiqi Qu Fazheng Ren Yixuan Li | 2023 | Food Science and Human Wellness2023,12,3: | 0 |
| 13 | Activation of insulin-like growth factor-1 receptor (IGF-1R) promotes growth of colorectal cancer through triggering the MEX3A-mediated degradation of RIG-Ⅰ显示文摘Insulin-like growth factor-1 receptor(IGF-1R) has been made an attractive anticancer target due to its overexpression in cancers.However,targeting it has often produced the disappointing results as the role played by cross talk with numerous downstream signalings.Here,we report a disobliging IGF-1R signaling which promotes growth of cancer through triggering the E3 ubiquitin ligase MEX3A-mediated degradation of RIG-I.The active β-arrestin-2 scaffolds this disobliging signaling to talk with MEX3A.In response to ligands,IGF-1Rβ activated the basal βarr2 into its active state by phosphorylating the interdomain domain on Tyr64 and Tyr250,opening the middle loop(Leu130-Cys141) to the RING domain of MEX3A through the conformational changes of βarr2.The models of βarr2/IGF-1Rβ and βarr2/MEX3A could interpret the mechanism of the activated-IGF-1R in triggering degradation of RIG-I.The assay of the mutants βarr2Y64Aand βarr2Y250Afurther confirmed the role of these two Tyr residues of the interlobe in mediating the talk between IGF-1Rβ and the RING domain of MEX3A.The truncated-βarr2 and the peptide ATQAIRIF,which mimicked the RING domain of MEX3A could prevent the formation of βarr2/IGF-1Rβ and βarr2/MEX3A complexes,thus blocking the IGF-1R-triggered RIG-I degradation.Degradation of RIG-I resulted in the suppression of the IFN-I-associated immune cells in the TME due to the blockade of the RIG-I-MAVS-IFN-I pathway.Poly(I:C) could reverse anti-PD-L1 insensitivity by recovery of RIG-I.In summary,we revealed a disobliging IGF-1R signaling by which IGF-1Rβ promoted cancer growth through triggering the MEX3A-mediated degradation of RIG-I. | Qiaobo Xie Yanyan Chu Wenmin Yuan Yanan Li Keqin Li Xinfeng Wu Xiaohui Liu Rui Xu Shuxiang Cui Xianjun Qu | 2023 | Acta Pharmaceutica Sinica B2023,13,7: | 0 |
| 14 | AC vector magnetometer for space-based applications using low-resource magneto-impedance sensor显示文摘This study proposes a novel AC vector magnetometer developed using a low-resource magneto-impedance sensor for China’s Feng-Yun meteorological satellite(FY-3E).It was calibrated and characterized to determine its performance parameters.The total weight of the AC vector magnetometer is 51 g(the aluminum box excluded),while the total power consumption is 310 m W.The proposed AC vector magnetometer can detect magnetic field variations in the range of±1000 nT and noise power spectral density of≤50 pT/Hz^(1/2)@1 Hz.Furthermore,the proposed device has a maximum nonlinearity of≤0.71‰over the entire range and a nonorthogonality error of 3.07 nT or 0.15%(root mean square).The total dose hardness of the sensor is≥30 krad(Si).Furthermore,we propose the first survey results of a magnetometer equipped aboard a Chinese FY-3E satellite in a Sunsynchronous orbit.The data revealed that the AC vector magnetometer can detect transient physical signals such as quasistatic field-aligned currents(~50 nT)and waves at the auroral latitudes.These features render the proposed AC vector magnetometer suitable for space-based applications,particularly those involving the study of geomagnetic activity. | YU XiangQian HUANG Cong XIAO ChiJie LI JiaWei LIU Si WANG JingDong LI YunPeng QU YaNan WANG YongFu CHEN HongFei ZOU Hong SHI WeiHong ZONG QiuGang CHEN XiaoFei ZHANG XiaoXin ZONG WeiGuo WANG JingSong | 2023 | Science China(Technological Sciences)2023,66,12: | 0 |
| 15 | The Dilemma and Way Out of China’s Participation in the Development of Marine Genetic Resources in ABNJ from the Perspective of BBNJ显示文摘The fifth intergovernmental negotiations on marine BBNJ(Biodiversity beyond Areas of National Jurisdiction)concluded in August 2022,in which there are still major differences regarding access to marine genetic resources,management,and technology transfer.China’s participation in the development of marine genetic resources in ABNJ(areas beyond national jurisdiction)has many dilemmas,which are linked to the difficulties faced in advancing the BBNJ negotiations.The following countermeasures are proposed at the institutional and practical levels respectively:clarifying the legal attributes and applicability of the principles of marine genetic resources;establishing mechanisms for access,management,environmental impact assessment and benefit sharing of marine genetic resources;and using the“Blue Partnership”to build a governance mechanism for marine genetic resources to achieve mutual benefits. | Qu Yanan Zhang Zixuan | 2023 | Journal of Shipping and Ocean Engineering2023,13,1: | 0 |
| 16 | Dilemma and Solutions of Greenhouse Gas Emission Reduction of International Shipping显示文摘How to build an international maritime GHG(greenhouse gas)emission reduction cooperation mechanism is an important international issue at present.Firstly,we describe the current situation of maritime transport GHG emission reduction and analyze the problems that still exist in international maritime transport emission reduction from four aspects:political,economic,legal and technical.For example,geopolitical aggravation hinders the solution of the FOC(Flag of Convenience)issue;maritime emissions are not included in the carbon emission trading system;the synergy of maritime emission reduction principles under the IMO(International Maritime Organization)framework and the technical level of maritime emission reduction needs to be improved.The motivation and essence of the divergent international actions on maritime emission reduction are discussed.Finally,it is proposed to implement the“true linkage principle”to solve the problem of FOCs;to promote the development of regional carbon markets and link them to the international maritime carbon emission trading market economically;to implement the CBDR(the common but differentiated responsibilities)principle legally to promote the international emission reduction work in an orderly manner;and the technical innovation of ships and increase the technical support. | Yanan Qu Jin Li | 2023 | Journal of Shipping and Ocean Engineering2023,13,1: | 0 |
| 17 | Tandem hydroalkylation and deoxygenation of lignin-derived phenolics to synthesize high-density fuels显示文摘Lignin is the most abundant naturally phenolic biomass,and the synthesis of high-performance renewable fuel from lignin has attracted significant attention.We propose the efficient synthesis of high-density fuels using simulated lignin cracked oil in tandem with hydroalkylation and deoxygenation reactions.First,we investigated the reaction pathway for the hydroalkylation of phenol,which competes with the hydrodeoxygenation form cyclohexane.And then,we investigated the effects of metal catalyst types,the loading amount of metallic,acid dosage,and reactant ratio on the reaction results.The phenol hydroalkylation and hydrodeoxygenation were balanced when 180℃ and 5 MPa H_(2)with the alkanes yield of 95%.By extending the substrate to other lignin-derived phenolics and simulated lignin cracked oil,we obtained the polycyclic alkane fuel with high density of 0.918 g·ml^(-1)and calorific value of41.2 MJ·L^(-1).Besides,the fuel has good low-temperature properties(viscosity of 9.3 mm^(2)·s^(-1)at 20℃ and freezing point below-55℃),which is expected to be used as jet fuel.This work provides a promising way for the easy and green production of high-density fuel directly from real lignin oil. | Rui Yu Zhensheng Shen Yanan Liu Chengxiang Shi Juncong Qu Lun Pan Zhenfeng Huang Xiangwen Zhan g Ji-Jun Zou | 2024 | Chinese Journal of Chemical Engineering2024,66,2: | 0 |
| 18 | Extracellular Milieu and Membrane Receptor Dual-Driven DNA Nanorobot for Accurate in Vivo Tumor Imaging显示文摘Precise diagnostic approaches have great potential in cancer intervention and prognosis.Although diverse DNA nanoprobes have been reported for tumor diagnosis,precise tumor imaging in vivo still encounters a great challenge due to the scarcity of exquisite design methodology.Herein,by assembling three programmable modules on a DNA triangular prism,we engineered a DNA nanorobot for simultaneous recognition of extracellular pH and cancer cell membrane receptor in an intelligent manner.Since the design uses two heterogeneous types of biomarkers as inputs,pH-RE not only could discriminate target tumor cells from similar cell mixtures with a recognition accuracy as high as 98.8%,but also could perform precise tumor imaging in living mice by intravenous injection.We expect that this extracellular pH and membrane receptor dual-driven DNA nanorobot will facilitate the establishment of a novel design paradigm for precise cancer diagnosis and therapy. | Kun Yuan Hong-Min Meng Yanan Wu Juan Chen Hui Xu Lingbo Qu Lele Li Zhaohui Li | 2022 | CCS Chemistry2022,4,5: | 0 |
