1Responses of ammonia-oxidizing microorganisms to biochar and compost amendments of heavy metals-polluted soil显示文摘Heavy metal pollution affects soil ecological function.Biochar and compost can effectively remediate heavy metals and increase soil nutrients.The effects and mechanisms of biochar and compost amendments on soil nitrogen cycle function in heavy-metal contaminated soils are not fully understood.This study examined how biochar,compost,and their integrated use affected ammonia-oxidizing microorganisms in heavy metal polluted soil.Quantitative PCR was used to determine the abundance of ammonia-oxidizing archaea(AOA)and bacteria(AOB).Ammonia monooxygenase(AMO)activity was evaluated by the enzymelinked immunosorbent assay.Results showed that compost rather than biochar improved nitrogen conversion in soil.Biochar,compost,or their integrated application significantly reduced the effective Zn and Cd speciation.Adding compost obviously increased As and Cu effective speciation,bacterial 16 S rRNA abundance,and AMO activity.AOB,stimulated by compost addition,was significantly more abundant than AOA throughout remediation.Correlation analysis showed that AOB abundance positively correlated with NO_(3)^(-)-N(r=0.830,P<0.01),and that AMO activity had significant correlation with EC(r=-0.908,P<0.01)and water-soluble carbon(r=-0.868,P<0.01).Those seem to be the most vital factors affecting AOB community and their function in heavy metal-polluted soil remediated by biochar and compost.Mingyue Li Jiachao Zhang Xiao Yang Yaoyu Zhou Lihua Zhang Yuan Yang Lin Luo Qingyun Yan 2021Journal of Environmental Sciences2021,33,4:5
2Three new zinc(Ⅱ) coordination polymers:Modulation of extended structures driven by assistant ligands显示文摘Three new complexes, [Zn(dtb)(4,4'-bipy)]·5H2O (1), [Zn(dtb)(bpp)]·H2O (2) and [Zn(dtb)(phen)2]·CH3CH2OH·H2O (3) (dtb = 5,5'-dithiobis(2-nitrobenzoic acid), 4,4'-bipy = 4,4'-bipyridine, bpp = 1,3-bi(4-pyridyl) propane, phen = 1,10-phenanthroline), have been constructed by dtb ligand and zinc salt in the presence of different assistant N-containing ligands under hydrothermal conditions. The structures of the complexes were established by single-crystal X-ray diffraction analysis. Although compounds 1 and 2 are both 2D networks, the cavities’ forms and pitch of helix are different. The structure of compound 3 shows a 1D helical chain, and is extended by the supermolecule interactions into a 2D framework. These neutral polymeric complexes exhibit structural and dimensional diversity due to the different coordination modes of the flexible dtb ligand and the effect of assistant ligands.DONG Zhe ZHANG WeiHong WANG YaoYu LIU RuiTing REN Chen SHI QiZhen 2009Chinese Science Bulletin2009,54,23:3
3GRP78 inhibits macrophage adhesion via SR-A显示文摘Class A scavenger receptor(SR-A)plays an important role in macrophage adhesion.However,the underlying mechanism remains unclear.We previously found that 78 kDa glucose-regulated protein(GRP78)inhibited SRA-mediated ligand internalization into macrophage by binding to SR-A.The aim of the study was to investigate whether GRP78 could regulate SR-A-mediated cell adhesion.We demonstrated that GRP78 bound directly to SR-A by fluorescence resonance energy transfer(FRET)assay.Overexpression of GRP78 inhibited macrophage adhesion via SR-A.These results suggest that GRP78 may act as an inhibitor of macrophage adhesion via SR-A.Hui Bai Nan Li Xiaodan Zhou Chenchen Wang Yan Zhang Xudong Zhu Min Huang Yaoyu Chen Xiaoyu Li Qing Yang Chaojun Li Jingjing Ben Qi Chen 2014The Journal of Biomedical Research2014,28,4:2
4In situ growth of hydrophilic nickel-cobalt layered double hydroxides nanosheets on biomass waste-derived porous carbon for high-performance hybrid supercapacitors显示文摘Rational design and cost-effective fabrication of layered double hydroxides(LDHs)nanosheets with extraordinary electrochemical performance is a key challenge for hybrid supercapacitors(HSCs).Herein,we report a facile in situ growth methodology to eco-friendly synthesize hydrophilic Ni Co-LDHs nanosheets on biomass waste-derived porous carbon(BC)for robust high-performance HSC cathode.The in situ growth process under ultrasonication realizes the rational arrangement of Ni Co-LDHs nanosheets on the surface of BC,which effectively increases the specific surface area,promotes the electronic conductivity and enhances the wettability of Ni Co-LDHs nanosheets without affecting their thickness values.With the beneficial effects of ultrathin thickness of LDHs nanosheets(6.20 nm),large specific surface area(2324.1 m^(2)g^(-1)),low charge transfer resistance(1.65Ω),and high wettability with electrolyte(34°–35°),the obtained Ni2Co1-LDHs/BC50 electrode possesses an ultra-high specific capacitance of 2390 F g^(-1)(956 C g^(-1))at 1 A g^(-1),which is superior to most reported values.Furthermore,an assembled Ni_(2)Co_(1)-LDHs/BC50//YP-80F HSC delivers a maximum specific energy of 52.47 Wh kg^(-1)at375 W kg^(-1),and maintains a high capacitance retention of 75.9%even after 4000 cycles.This work provides a facile approach to fabricate LDHs nanosheets based cathode materials for high-performance HSCs.Yuchen Wang Yaoyu Liu Zuo Chen Man Zhang Biying Liu Zhenhao Xu Kai Yan 2022Green Chemical Engineering2022,3,1:1

9Solvatochromic Probe Based on Nanocellulose Membrane Coated with Zn-terpyridine Complex in a Layer-by-Layer Manner显示文摘Solvatochromic materials have recently attracted increasing attention owing to their great significance in the security and sensor fields.In this study,ultrafast explicit and implicit information was collected regarding a fluorescent nanocellulose membrane produced from nanocellulose membranes coated with a Zn-terpyridine complex(Zn-tpy)in a layer-by-layer manner.The fluorescent emissions of the nanocellulose membrane changed from yellow(CIE:x=0.37,y=0.45)to green(CIE:x=0.32,y=0.47)under a dichloromethane environment and 365-nm irradiation.Due to the ease of dichloromethane volatilization,fluorescent emissions quickly returned to the original state.These solvatochromic nanocellulose membranes,with ultrafast explicit and implicit information,exhibited valuable application prospects in anti-counterfeiting techniques.XinPing Li FaFa Song Meng Zhang BaiLiang Xue JingYi Nie ShunTian Jia YaoYu Wang Zhao Zhang 2019Paper And Biomaterials2019,4,2:1

11The relative importance of soil moisture in predicting bacterial wilt disease occurrence显示文摘Soil-borne plant diseases cause major economic losses globally.This is partly because their epidemiology is difficult to predict in agricultural fields,where multiple environmental factors could determine disease outcomes.Here we used a combination of field sampling and direct experimentation to identify key abiotic and biotic soil properties that can predict the occurrence of bacterial wilt caused by pathogenic Ralstonia solanacearum.By analyzing 139 tomato rhizosphere soils samples isolated from six provinces in China,we first show a clear link between soil properties,pathogen density and plant health.Specifically,disease outcomes were positively associated with soil moisture,bacterial abundance and bacterial community composition.Based on soil properties alone,random forest machine learning algorithm could predict disease outcomes correctly in 75%of cases with soil moisture being the most significant predictor.The importance of soil moisture was validated causally in a controlled greenhouse experiment,where the highest disease incidence was observed at 60%of maximum water holding capacity.Together,our results show that local soil properties can predict disease occurrence across a wider agricultural landscape,and that management of soil moisture could potentially offer a straightforward method for reducing crop losses to R.solanacearum.Gaofei Jiang Ningqi Wang Yaoyu Zhang Zhen Wang Yuling Zhang Jiabao Yu Yong Zhang Zhong Wei Yangchun Xu Stefan Geisen Ville-Petri Friman Qirong Shen 2021Soil Ecology Letters2021,3,4:1
12A novel long-term intravenous combined with local treatment with human amnion-derived mesenchymal stem cells for a multidisciplinary rescued uremic calciphylaxis patient and the underlying mechanism显示文摘Calciphylaxis is a rare disease characterized histologically by microvessel calcification and microthrombosis,with high mortality and no proven therapy.Here,we reported a severe uremic calciphylaxis patient with progressive skin ischemia,large areas of painful malodorous ulcers,and mummified legs.Because of the worsening symptoms and signs refractory to conventional therapies,treatment with human amnion-derived mesenchymal stem cells(hAMSCs)was approved.Preclinical release inspections of hAMSCs,efficacy,and safety assessment,including cytokine secretory ability,immunocompetence,tumorigenicity,and genetics analysis in vitro,were introduced.We further performed acute and long-term hAMSC toxicity evaluations in C57BL/6 mice and rats,abnormal immune response tests in C57BL/6 mice,and tumorigenicity tests in neonatal Balbc-nu nude mice.After the preclinical research,the patient was treated with hAMSCs by intravenous and local intramuscular injection and external supernatant application to the ulcers.When followed up to 15 months,the blood-based markers of bone and mineral metabolism improved,with skin soft tissue regeneration and a more favorable profile of peripheral blood mononuclear cells.Skin biopsy after 1-month treatment showed vascular regeneration with mature noncalcified vessels within the dermis,and 20 months later,the re-epithelialization restored the integrity of the damaged site.No infusion or local treatment-related adverse events occurred.Thus,this novel long-term intravenous combined with local treatment with hAMSCs warrants further investigation as a potential regenerative treatment for uremic calciphylaxis due to effects of inhibiting vascular calcification,stimulating angiogenesis and myogenesis,anti-inflammatory and immune modulation,multidifferentiation,re-epithelialization,and restoration of integrity.Lianju Qin Jing Zhang Yujie Xiao Kang Liu Yugui Cui Fangyan Xu Wenkai Ren Yanggang Yuan Chunyan Jiang Song Ning Xiaoxue Ye Ming Zeng Hanyang Qian Anning Bian Fan Li Guang Yang Shaowen Tang Zhihong Zhang Juncheng Dai Jing Guo Qiang Wang Bin Sun Yifei Ge Chun Ouyang Xueqiang Xu Jing Wang Yaoyu Huang Hongqing Cui Jing Zhou Meilian Wang Zhonglan Su Yan Lu Di Wu Jingping Shi Wei Liu Li Dong Yinbing Pan Baiqiao Zhao Ying Cui Xueyan Gao Zhanhui Gao Xiang Ma Aiqin Chen Jie Wang Meng Cao Qian Cui Li Chen Feng Chen Youjia Yu Qiang Ji Zhiwei Zhang Mufeng Gu Xiaojun Zhuang Xiaolin Lv Hui Wang Yanyan Pan Ling Wang Xianrong Xu Jing Zhao Xiuqin Wang Cuiping Liu Ningxia Liang Changying Xing Jiayin Liu Ningning Wang 2022Journal of Molecular Cell Biology2022,14,2:1
13Fe_(3)O_(4) Nanoparticle‑modified Multi‑walled Carbon Nanotubes for the Determination of Synthetic Pyrethroids in Human Blood显示文摘In this study,a sensitive and rapid magnetic solid‑phase microextraction(MSPE)procedure based on Fe_(3)O_(4) nanoparticle‑modified,multi‑walled carbon nanotubes combined with a gas chromatography/electron capture detector(GC/ECD)was developed to quantify pyrethroids in human blood samples.This study compared liquid-liquid extraction and solid‑phase extraction methods and found that the MSPE‑GC/ECD method had many advantages,such as high recovery rate,high extraction efficiency,high detection sensitivity,low limit of detection,and simple operation.It can meet the actual requirements for the determination of synthetic pyrethroids in human blood.Cui Yanhua Shen Weidong Yang Fan Pan Yaoyue Zhang Suling Yao Weixuan 2019Journal of Forensic Science and Medicine2019,5,3:0
14Electrodeposited 3D hierarchical NiFe microflowers assembled from nanosheets robust for the selective electrooxidation of furfuryl alcohol显示文摘A robust and green strategy for the selective upgrading of biomass-derived platform chemicals towards highly valuable products is important for the sustainable development.Herein,the efficient electrocatalytic oxidation of biomass-derived furfuryl alcohol(FFA)into furoic acid(FurAc)catalyzed by the electrodeposited non-precious NiFe microflowers was successfully reached under the low temperature and ambient pressure.The 3D hierarchical NiFe microflowers assembled from ultrathin nanosheets were controllably synthesized by the electrodeposition method and uniformly grown on carbon fiber paper(CFP).Electrochemical analysis confirmed that NiFe nanosheets more preferred in the selective oxidation of FFA(FFAOR)than oxygen evolution reaction(OER).The linear sweep voltammetry(LSV)in FFAOR displayed a clear decrease towards lower potential,resulting in 30 mV reduction of overpotential at 20 mA cm^(-2) compared with that of OER.The optimal catalyst Ni_(1)Fe_(2) nanosheets exhibited the highest selectivity of FurAc(94.0%)and 81.4%conversion of FFA within 3 h.Besides,the influence of various reaction parameters on FFAOR was then explored in details.After that,the reaction pathway was investigated and rationally proposed.The outstanding performance for FFAOR can be ascribed to the unique structure of 3D flower-like NiFe nanosheets and oxygen vacancies,resulting in large exposure of active sites,faster electron transfer and enhanced adsorption of reactants.Our findings highlight a facile and convenient mean with a promising green future,which is promising for processing of various biomass-derived platform chemicals into value-added products.Biying Liu Man Zhang Yaoyu Liu Yuchen Wang Kai Yan 2023Green Energy & Environment2023,8,3:0
15Temperature-and field angular-dependent helical spin period characterized by magnetic dynamics in a chiral helimagnet MnNb_(3)S_(6)显示文摘The chiral magnets with topological spin textures provide a rare platform to explore topology and magnetism for potential application implementation.Here,we study the magnetic dynamics of several spin configurations on the monoaxial chiral magnetic crystal MnNb_(3)S_(6)via broadband ferromagnetic resonance(FMR)technique at cryogenic temperature.In the high-field forced ferromagnetic state(FFM)regime,the obtained frequency f vs.resonance field H_(res) dispersion curve follows the wellknown Kittel formula for a single FFM,while in the low-field chiral magnetic soliton lattice(CSL)regime,the dependence of H_(res) on magnetic field angle can be well-described by our modified Kittel formula including the mixture of a helical spin segment and the FFM phase.Furthermore,compared with the sophisticated Lorentz micrograph technique,the observed magnetic dynamics corresponding to different spin configurations allow us to obtain temperature-and field-dependent proportion of helical spin texture and helical spin period ratio L(H)/L(0)via our modified Kittel formula.Our results demonstrated that fieldand temperature-dependent nontrivial magnetic structures and corresponding distinct spin dynamics in chiral magnets can be an alternative and efficient approach to uncovering and controlling nontrivial topological magnetic dynamics.Liyuan Li Haotian Li Kaiyuan Zhou Yaoyu Gu Qingwei Fu Lina Chen Lei Zhang Ronghua Liu 2023Science China(Physics,Mechanics & Astronomy)2023,66,1:0
16Efficient electrooxidation of biomass-derived aldehydes over ultrathin Ni V-layered double hydroxides films显示文摘Selective upgrading of C=O bonds to afford carboxylic acid is significant for the petrochemical industry and biomass utilization.Here we declared the efficient electrooxidation of biomass-derived aldehydes family over NiV-layered double hydroxides(LDHs) thin films.Mechanistic studies confirmed the hydroxyl active intermediate(-OH*) generated on the surface of NiV-LDHs films by employing electrochemical impedance spectroscopy and the electron paramagnetic resonance spectroscopy.By using advanced techniques,e.g.,extended X-ray absorption fine structure and high-angle annular dark-field scanning transmission electron microscopy,NiV-LDHs films with 2.6 nm could expose larger specific surface area.Taking benzaldehyde as a model,high current density of 200 mA cm^(-2)at 1.8 V vs.RHE,81.1% conversion,77.6% yield of benzoic acid and 90.8% Faradaic efficiency were reached,which was superior to most of previous studies.Theoretical DFT analysis was well matched with experimental findings and documented that NiV-LDHs had high adsorption capacity for the aldehydes to suppress the side reaction,and the aldehydes were oxidized by the electrophilic hydroxyl radicals formed on NiV-LDHs.Our findings offer a universal strategy for the robust upgrading of diverse biomass-derived platform chemicals.Biying Liu Zhikeng Zheng Yaoyu Liu Man Zhang Yuchen Wang Yangyang Wan Kai Yan 2023Journal of Energy Chemistry2023,,3:0
17Experimental and numerical investigation of a composite structure with frame and skin显示文摘A composite structure with frame and skin based on cabin structure in a large space telescope is studied in this paper.The frame is composed of longitudinal and transverse beams with hybrid bonded/bolted joints,and the skin is connected to the frame by bolts.Tensile tests are conducted on the structure by a set of test stand.It is observed that residual deformation occurs in the first test of the structure,which is attributed to the relative sliding between the skin and frame because of bolt-hole clearances.The high tightening torque and the increased number of the skin-frame bolts contribute to the high stiffness of the structure.A finite element model(FEM)of this composite structure is established,and the simulation model is verified by the experimental results.The FEM is contrastively analyzed with different frame joints,and it is found that adhesive joining in the hybrid bonded/bolted joints enhances the stiffness of the structure significantly.Given that adhesive plays a leading role in the stiffness of the hybrid joints,Tie contact in FEM is proposed to simulate bonded or hybrid joints when studying the stiffness performance of undamaged structure.李传政 XU Shuyan DONG Jihong LIU Bo ZHANG Yaoyu ZHENG Fusheng 2023High Technology Letters2023,29,1:0
18Theoretical and practical guide for an axial superresolved focus via Gouy phase steering显示文摘Achieving an axial superresolved focus with a single lens by simply inserting a modulation mask in the pupil plane is preferred due to its compact configuration and general applicability. However, lack of a universal theoretical model to manifest the superresolved focusing mechanism vastly complicates the mask design and hinders optimal resolution. Here we establish an interference model and find out that the axial resolution closely relates to the Gouy phase gradient(GPG) at the focal point. Using a GPG tuning-based optimization approach, the axial resolution of a ring-mask-modulated beam is readily improved to attain superresolved focal depth for multiple types of pupil function and polarization. In experiment, a focus with an axial resolution of 27% improved from the diffraction limit and 11% finer than the previously reported record is demonstrated for the radially polarized beam. In simulations, a spherical focus with 3D isotropic resolution and a superoscillation-like axial modulation behavior toward extremely high axial resolution is also presented. This approach can be applied for varied types of pupil function, wavelength, and polarization, and can be easily transferred to other traditional or superresolution microscopes to upgrade their axial resolution.XIAOWEI LIU XIAOLAN XIA ZHUOFAN YAO TIANYUE ZHANG MEILING JIANG QING YANG XIANGPING LI YAOYU CAO 2022Photonics Research2022,10,11:0
19Unraveling the role of iron on Ni-Fe alloy nanoparticles during the electrocatalytic ethanol-to-acetate process显示文摘The anodic electrooxidation of ethanol to value-added acetate is an excellent example of replacing the oxygen evolution reaction to promote the cathodic hydrogen evolution reaction and save energy.Herein,we present a colloidal strategy to produce Ni-Fe bimetallic alloy nanoparticles(NPs)as efficient electrocatalysts for the electrooxidation of ethanol in alkaline media.Ni-Fe alloy NPs deliver a current density of 100 mA·cm^(-2) in a 1.0 M KOH solution containing 1.0 M ethanol merely at 1.5 V vs.reversible hydrogen electrode(RHE),well above the performance of other electrocatalysts in a similar system.Within continuous 10 h testing at this external potential,this electrode is able to produce an average of 0.49 mmol·cm^(-2)·h^(-1) of acetate with an ethanol-to-acetate Faradaic efficiency of 80%.A series of spectroscopy techniques are used to probe the electrocatalytic process and analyze the electrolyte.Additionally,density functional theory(DFT)calculations demonstrate that the iron in the alloy NPs significantly enhances the electroconductivity and electron transfer,shifts the rate-limiting step,and lowers the energy barrier during the ethanol-to-acetate reaction pathway.Junshan Li Luming Li Xinyu Ma Jun Wang Jun Zhao Yu Zhang Ren He Yaoyue Yang Andreu Cabot Yongfa Zhu 2024Nano Research2024,17,4:0
20Identification of a receptor tyrosine kinase inhibitor CP-724714 inhibits SADS-CoV related swine diarrhea coronaviruses infection in vitro显示文摘The outbreak of the COVID-19 epidemic in 2020 has caused unprecedented panic among all mankind,pointing the major importance of effective treatment.Since the emergence of the swine acute diarrhea syndrome coronavirus(SADS-CoV)at the end of 2017,multiple reports have indicated that the bat-related SADS-CoV possesses a potential threat for cross-species transmission.Vaccines and antiviral drugs development deserve more attention.In this study,we found that the HER2 phosphorylation inhibitor(CP-724714)inhibited SADS-CoV infection in a dose-dependent manner.Further validation demonstrated that CP-724714 affected at the post-entry stage of SADS-CoV infection cycle.Also,efficient SADS-CoV infection required the activation of HER2 and its cascade Ras-Raf-Mek-Erk signaling pathway.In addition,CP-724714 has a broad-spectrum anti-swine diarrhea coronaviruses activity,and can dose-dependently combat SADS-CoV,porcine epidemic diarrhea virus(PEDV),porcine deltacoronavirus(PDCoV)and transmissible gastroenteritis virus(TGEV)infection in vitro with a specificity index of greater than 21.98,9.38,95.23 and 31.62,respectively.These results highlight the potential utility of CP-724714 or antiviral drugs targeting with HER2 and its cascade Ras-Raf-Mek-Erk signaling pathway as host-targeted SADS-CoV and other related coronaviruses therapeutics.Ling Zhou Cheng Li Ruiyu Zhang Qianniu Li Yuan Sun Yaoyu Feng Tian Lan Jingyun Ma 2023Virologica Sinica2023,38,5:0
