| 1 | Superlubricity achieved with two-dimensional nano-additives to liquid lubricants显示文摘The topic of superlubricity is attracting considerable interest around the world while humanity is facing an energy crisis.Since various liquid superlubricity systems can be commonly achieved on the macroscale in ambient conditions,it is considered an effective solution to reduce unnecessary energy and material losses.However,certain practical problems such as low load-bearing pressure,dependence on hydrogen ions,and relatively long running-in processes still limit its widespread application.Two-dimensional(2D)nano-additives with ultrathin longitudinal dimensions can lower the shear resistance between sliding solid surfaces,and thus further optimize the applied conditions.In this review,the latest studies on 2D nano-additives with a combination of various water-based lubricants in the state of superlubricity are reported,typically including black phosphorus(BP),graphene oxide(GO),and layered double hydroxide.During the sliding process,composite lubricants effectively improved the load capacity(up to 600 MPa),reduced wear,and accelerated the running-in period(within 1,000 s)of the liquid superlubricity system.Both macromechanical experiments and microscopic tests are conducted to precisely analyze various interactions at the interfaces of the nano-additives and solid surfaces.These interactions can be described as tribochemical reactions,physical protection,and adsorption enhancement,and improved wear resistance.This review provides better guidance for applying 2D nanomaterials in liquid superlubricity systems. | Hongdong WANG Yuhong LIU | 2020 | Friction2020，8，6： | 6 |
| 2 | The RALF1-FERONIA Complex Phosphorylates eIF4E1 to Promote Protein Synthesis and Polar Root Hair Growth显示文摘The molecular links between extracellular signals and the regulation of localized protein synthesis in plant cells are poorly understood.Here,we show that in Arabidopsis thaliana,the extracellular peptide RALF1 and its receptor,the FERONIA receptor kinase,promote root hair(RH)tip growth by modulating protein synthesis.We found that RALF1 promotes FERONIA-mediated phosphorylation of elF4E1,a eukaryotic translation initiation factor that plays a crucial role in the control of mRNA translation rate.Phosphorylated elF4E1 increases mRNA affinity and modulates mRNA translation and,thus,protein synthesis.The mRNAs targeted by the RALF1-FERONIA-elF4E1 module include ROP2 and RSL4,which are important regulators of RH cell polarity and growth.RALF1 and FERONIA are expressed in a polar manner in RHs,which facilitate elF4E1 polar丨ocalization and thus may control local f?OP2 translation.Moreover,we demonstrated that high-level accumulation of RSL4 exerts negative-feedback regulation of RALF1 expression by directly binding the RALF1 gene promoter,determining the final RH size.Our study reveals that the link between RALF1-FERONIA signaling and protein synthesis constitutes a novel component regulating cell expansion in these polar growing cells. | Sirui Zhu Jose Manuel Estevez Hongdong Liao Yonghua Zhu Tao Yang Chiyu Li Yichuan Wang Lan Li Xuanming Liu Javier Martinez Pacheco Hongwei Guo Feng Yu | 2020 | Molecular Plant2020，13，5： | 3 |
| 3 | Nematode-Encoded RALF Peptide Mimics Facilitate Parasitism of Plants through the FERONIA Receptor Kinase显示文摘The molecular mechanism by which plants defend against plant root-knot nematodes(RKNs)is largely unknown.The plant receptor kinase FERONIA and its peptide ligands,rapid alkalinization factors(RALFs),regulate plant immune responses and cell expansion,which are two important factors for successful RKN parasitism.In this study,we found that mutation of FERONIA in Arabidopsis thaliana resulted in plants showing low susceptibility to the RKN Meloidogyne incognita.To identify the underlying mechanisms associated with this phenomenon,we identified 18 novel RALF-likes from multiple species of RKNs and showed that two RALF-likes(i.e.,MiRALF1 and MiRALF3)from M.incognita were expressed in the esophageal gland with high expression during the parasitic stages of nematode development.These nematode RALF-likes also possess the typical activities of plant RALFs and can directly bind to the extracellular domain of FERONIA to modulate specific steps of nematode parasitism-related immune responses and cell expansion.Genetically,both MiRALF1/3 and FERONIA are required for RKN parasitism in Arabidopsis and rice.Collectively,our study suggests that nematode-encoded RALFs facilitate parasitism via plant-encoded FERONIA and provides a novel paradigm for studying host-pathogen interactions. | Xin Zhang Huan Peng Sirui Zhu Junjie Xing Xin Li Zhaozhong Zhu Jingyuan Zheng Long Wang Bingqian Wang Jia Chen Zhenhua Ming Ke Yao Jinzhuo Jian Sheng Luan Devin Coleman-Derr Hongdong Liao Yousong Peng Deliang Peng Feng Yu | 2020 | Molecular Plant2020，13，10： | 3 |
| 4 | Tribological properties of novel palygorskite nanoplatelets used as oil-based lubricant additives显示文摘Layered palygorskite(PAL),commonly called attapulgite,is a natural inorganic clay mineral composed of magnesium silicate.In this study,an aqueous miscible organic solvent treatment method is adopted to prepare molybdenum-dotted palygorskite(Amo-PMo)nanoplatelets,which greatly improved the specific surface area of PAL and the dispersion effect in an oil-based lubricant system.Their layered structure and size were confirmed using transmission electron microscopy(TEM)and atomic force microscopy.Following a tribological test lubricated with three additives(PAL,organic molybdenum(SN-Mo),and Amo-PMo),it was found that the sample of 0.5 wt%Amo-PMo exhibited the best tribological properties with a coefficient of friction of 0.09.Moreover,the resulting wear scar diameter and wear volume of the sliding ball surface were 63%and 49.6%of those lubricated with base oil,respectively.Its excellent lubricating performance and self-repairing ability were mainly attributed to the generated MoS2 adsorbed on the contact surfaces during the tribochemical reaction,thereby effectively preventing the direct collision between asperities on sliding solid surfaces.Thus,as-prepared Amo-PMo nanoplatelets show great potential as oil-based lubricant additives,and this study enriches the existing application of PAL in industry. | Kunpeng WANG Huaichao WU Hongdong WANG Yuhong LIU Lv YANG Limei ZHAO | 2021 | Friction2021，9，2： | 3 |
| 5 | Development and application of tumor-targeting magnetic nanoparticles FA-StNP@Fe_2O_3 for hyperthermia显示文摘Modified magnetic starch nanoparticles (FA-StNP@Fe2O3) were synthesized by conjugating folic acid (FA-PEG-NH2) onto the surface of magnetic starch nanoparticles (StNP@Fe2O3) prepared by reverse microemulsion method. The synthesized FA-StNP@Fe2O3 was investigated by transmission electron microscopy and zeta potential analysis. The average size of its well dispersed particles was 250 nm. The iron concentration of 2 mg/g was detected by phenanthroline method. Placing FA-StNP@Fe2O3 nanoparticles in the alternating magnetic field for 30 min resulted in an increase in the suspension temperature from ambient temperature (37℃) to a value between 42℃ and 43℃. Co-cultured nanoparticles and Hela cell line or normal HUEC-12 cell line, and the biological effects at the cellular level were investigated in the alternating magnetic field using MTT assay, Hochest-PI double staining and flow cytometry analysis. Experimental results showed that FA-StNP@Fe2O3 within acertain concentration range has no obvious effect on cell proliferation. When treated in the magnetic field, apoptosis rate on Hela induced by FA-StNP@Fe2O3 was 13.4%. Prussian blue staining analysis confirmed that the nanoparticles modified with folic acid had improved ability in tumor cell-targeting, and therefore, potential applications in biomedical and magnetocaloric areas. It is expected be applied in tumor targeting therapy in the near future. | ZHENG YuanQing TONG ChunYi WANG Bei XIE Ying LIAO HongDong LI Dan LIU XuanMing | 2009 | Chinese Science Bulletin2009，54，17： | 3 |
| 6 | Functional modules with disease discrimination abilities for various cancers显示文摘Selecting differentially expressed genes(DEGs) is one of the most important tasks in microarray applications for studying multi-factor diseases including cancers.However,the small samples typically used in current microarray studies may only partially reflect the widely altered gene expressions in complex diseases,which would introduce low reproducibility of gene lists selected by statistical methods.Here,by analyzing seven cancer datasets,we showed that,in each cancer,a wide range of functional modules have altered gene expressions and thus have high disease classification abilities.The results also showed that seven modules are shared across diverse cancers,suggesting hints about the common mechanisms of cancers.Therefore,instead of relying on a few individual genes whose selection is hardly reproducible in current microarray experiments,we may use functional modules as functional signatures to study core mechanisms of cancers and build robust diagnostic classifiers. | YAO Chen ZHANG Min ZOU JinFeng LI HongDong WANG Dong ZHU Jing GUO Zheng | 2011 | Science China(Life Sciences)2011，54，2： | 3 |
| 7 | Coordination engineering of cobalt phthalocyanine by functionalized carbon nanotube for efficient and highly stable carbon dioxide reduction at high current density显示文摘Coordination engineering can enhance the activity and stability of the catalyst in heterogeneous catalysis.However,the axial coordination engineering between different groups on the carbon carrier and molecular catalysts in the electrocatalytic carbon dioxide reduction reaction(CO_(2)RR)has been studied rarely.Through coordination engineering strategy,a series of amino(NH_(2)),hydroxyl(OH),and carboxyl(COOH)groups functionalized carbon nanotubes(CNT)immobilized cobalt phthalocyanine(CoPc)catalysts are designed.Compared with no groups,OH groups and COOH groups,NH_(2)groups can effectively change the coordination environment of the central metal Co,thereby significantly increasing the turnover frequency(TOF)(31.4 s^(-1)at-0.6 V vs.RHE,CoPc/NH_(2)-CNT>CoPc/OH-CNT>CoPc/COOH-CN>CoPc/CNT).In the flow cell,the CoPc/NH_(2)-CNT catalyst has high carbon monoxide(CO)selectivity at high current density(~100%at-225 mA·cm^(-2),~96%at-351 mA·cm^(-2)).Importantly,the CoPc/NH_(2)-CNT catalyst can operate stably for 100 h at 225 mA·cm^(-2).Theoretical calculations reveal that CoPc/NH_(2)-CNT catalyst is beneficial to the formation of^(*)COOH and desorption of^(*)CO,thus promoting CO_(2)RR.This work provides an excellent platform for understanding the effect of coordination engineering on electrocatalytic performance and promotes a way to explore efficient and stable catalysts in other applications. | Hongdong Li Yue Pan Zuochao Wang Yaodong Yu Juan Xiong Haoyang Du Jianping Lai Lei Wang Shouhua Feng | 2022 | Nano Research2022，15，4： | 2 |
| 8 | Simulation and experiment of a transplanting mechanism for sweet potato seedlings with ‘boat-bottom’ transplanting trajectory显示文摘Planting on mulched soil is the main cultivation mode for sweet potato slips in spring in northern China.The‘boatbottom’planting method can bring high quantity and similar size for sweet potatoes.In this study,a mechanism for transplanting sweet potato seedlings on mulched was proposed,which could realize‘boat-bottom’transplanting trajectory and improve the planting efficiency.The virtual prototype model of the transplanting mechanism was constructed using ADAMS software,a soil particle model and a flexible body model of sweet potato seedling were established using EDEM software,and then a joint simulation was carried out to find out the interaction of mechanism,seedling and soil.By simulation,the trajectory of the clamping point,the sweet potato seedling posture,soil particles,pits,and relative force were all analyzed,which verified the rationality of the transplanting mechanism design.Finally,three kinds of sweet potato seedlings,watermelon red,Yan-25,and purple sweet potato seedlings were selected,and transplanting experiments were carried out on the mulch to verify that the theoretical trajectory,the simulated trajectory,and the actual trajectory were consistent.The transplanting success rates of the three kinds of sweet potato seedlings were all above 85%,indicating that different varieties of sweet potato seedlings had little effect on the transplanting effect of the mechanism,which reflected that the transplanting mechanism had good practicability and adaptability. | Yuanyuan Shao Hongdong Zhang Guantao Xuan Tao Zhang Xianlu Guan Fuhui Wang | 2023 | International Journal of Agricultural and Biological Engineering2023，16，3： | 1 |

| 16 | Hot electron assisted photoelectrochemical water splitting from Audecorated ZnO@TiO_(2) nanorods array显示文摘Engineering of semiconductor nanomaterials is critical to enhance the photoelectrochemical(PEC)performance for water splitting.However,semiconductors often show the low light absorption,slow charge transfer,and easy recombination of carriers,thus leading to the low catalytic efficiency.In this work,we show facile synthesis of ZnO@TiO_(2) core–shell nanorods(NRs)arrays modified with Au nanoparticles(NPs)as the photoelectrode for PEC water splitting.Impressively,the obtained ZnO@TiO_(2)(15 nm)/Au(8 nm)array shows the maximum photocurrent density of 3.14 mA/cm^(2) at 1.2 V vs.reversible hydrogen electrode(RHE),2.6 times and 1.7 times higher than those obtained from ZnO NRs and ZnO@TiO_(2)(15 nm)arrays.The electric-field simulation and transient absorption spectroscopy show that the Au-decorated core–shell nanostructures have an enhanced hot electron generation and prolonged decay time,indicating effective charge transfer and recombination inhibition of carriers.This work provides an efficient preparation strategy for photoelectrodes as well as great potential for the large-scale development of this technology. | Hongdong Li Hongyan Liu Fei Wang Guodong Li Xiaoli Wang Zhiyong Tang | 2022 | Nano Research2022，15，7： | 0 |
| 17 | Adjustable superlubricity system using polyalkylene glycol with various acid aqueous solutions显示文摘Polyalkylene glycol(PAG)aqueous solutions have recently been demonstrated to exhibit an ultralow friction coefficient(COF,μ<0.01).However,the prolonged running-in period and low bearing capacity have limited its widespread application.In this study,we determined that the running-in period can be decreased by more than 75%when the pH value of the lubricant is controlled at 3 by introducing various acid solutions.Additionally,less time was required to realize stable superlubricity with inorganic acid at lower pH values.This was mainly attributed to the acceleration effect of hydrogen ions around the contact region.In case of PAG aqueous solution with organic acid,the wear loss between sliding solid surfaces was reduced,and thus the bearing pressure during the superlubricity period was significantly improved from approximately 30 to 160 MPa.Furthermore,the organic acid molecules were considered to form strong hydrogen bonds with PAG macromolecules and solid surfaces.This in turn strengthened the structure of the adsorption layers.The unique effect of different acids in aqueous polymer lubrication can potentially significantly aid in advancing the study of polymer tribology and broadening industrial applications. | Wenrui LIU Hongdong WANG Yuhong LIU | 2023 | Friction2023，11，7： | 0 |

| 19 | High-Speed Parallel Plasmonic Direct-Writing Nanolithography Using Metasurface-Based Plasmonic Lens显示文摘Simple and efficient nanofabrication technology with low cost and high flexibility is indispensable for fundamental nanoscale research and prototyping.Lithography in the near field using the surface plasmon polariton(i.e.,plasmonic lithography)provides a promising solution.The system with high stiffness passive nanogap control strategy on a high-speed rotating substrate is one of the most attractive highthroughput methods.However,a smaller and steadier plasmonic nanogap,new scheme of plasmonic lens,and parallel processing should be explored to achieve a new generation high resolution and reliable efficient nanofabrication.Herein,a parallel plasmonic direct-writing nanolithography system is established in which a novel plasmonic flying head is systematically designed to achieve around 15 nm minimum flying-height with high parallelism at the rotating speed of 8–18 m·s^(-1).A multi-stage metasurface-based polarization insensitive plasmonic lens is proposed to couple more power and realize a more confined spot compared with conventional plasmonic lenses.Parallel lithography of the nanostructures with the smallest(around 26 nm)linewidth is obtained with the prototyping system.The proposed system holds great potential for high-freedom nanofabrication with low cost,such as planar optical elements and nano-electromechanical systems. | Yueqiang Hu Ling Li Rong Wang Jian Song Hongdong Wang Huigao Duan Jiaxin Ji Yonggang Meng | 2021 | Engineering2021，7，11： | 0 |
| 20 | Hierarchical self-assembled structure and frictional response of phthalocyanine molecules显示文摘Solid evidence is needed to demonstrate the effect of molecular orientation and structure on the frictional property of boundary lubricants.In this work,the frictional properties of phthalocyanine self-assembled monolayers(SAMs)with face-on(aromatic cores parallel to the substrate)and edge-on(aromatic cores stand on the substrate)orientations have been compared and the in situ structural variation of edge-on SAMs under frictional shear has been revealed by atomic force microscope(AFM).Face-on oriented SAMs show lower adhesion,lower friction,and stronger wear resistance,compared with edge-on oriented SAMs.Hierarchical structures of edge-on oriented SAMs have been revealed by frictional topography,which are consisted of nanoscale columns,micron-scale stripes,and centimeter-scale monolayer.The column structure deforms under increasing load force,leading to a stepwise friction force curve and a transition among three friction states(ordered friction,collapsed friction,and worn friction).The structural deformation depends on both the order degree and anisotropic stiffness of columns.Columns in phthalocyanine SAMs show a larger stiffness when shearing against molecular plane than shearing along the molecular plane.The presented study on the interfacial structure and frictional mechanism promisingly supports the designing of novel boundary lubricants and their application in engineering. | Yijun QIAO Jian SONG Hongyu SHI Hongdong WANG Shizhu WEN Yuhong LIU | 2023 | Friction2023，11，3： | 0 |
