| 1 | Synthesis and Application of Novel Triazine-Based Charring-Foaming Agents in Intumescent Flame Retardant Polypropylene显示文摘Three novel triazine-based charring-foaming agents (M2-CFA,M4-CFA,and M6-CFA) were synthesized successfully with only water as the solvent and were characterized by FT-IR and thermal gravimetric analysis (TGA).These three charring-foaming agents and the byproduct 944-by were employed to study the effectiveness of the novel intumescent flame retardant dopant on the fire retardancy of polypropylene (PP) investigated through UL-94 and limiting oxygen index (LOI) tests.TGA results showed that the M4-CFA presented good char formation ability (char residue: 26.8% at 700 ℃).It was found that the sample with a 2/1 mass ratio of APP to M4-CFA exhibited the best flame retardancy among all the PP composites: 35.5% LOI and a V-0 rating of UL-94.Additionally,the microstructure and morphology of char residues were further studied by XRD,Raman spectroscopy and SEM. | Ligong Chen Yanyan Yuan Bowei Wang Na Liu Yuzhi Xing Yang Li | 2017 | Transactions of Tianjin University2017，23，3： | 9 |
| 2 | EGFR signaling augments TLR4 cell surface expression and function in macrophages via regulation of Rab5a activation显示文摘Dear Editor,oll-like receptor 4(TLR4)is a key receptor sensing bacterial lipopolysaccharide(LPS),and is the most investigated member of the Tol-like receptor family(Kawai and Akira,2007;Kayagaki et al,2013;Klein et al.,2015).Cell surface TLR4 expression is determined by the balance between receptor trafficking from the Golgi apparatus to the cell membrane,and internalization of the cell surface receptor into endosomal compartments(Saltoh,2009).In bone mar-row-derived macrophages(BMDM),we observed LPS-in-duced EGFR phosphorylation on the surface of BMDM,and this was inhibited by pretreatment with PD168393 or TAPI-1(Fig.S1).Next,we measured dynamic changes in cell sur-face TLR4 expression after LPS treatment.At6,12,and 24 h after LPS treatment,TLR4 expression on the surface of BMDM was increased^2-,~6-,and^9-fold,respectively,as compared with controls. | Jing Tang Bowei Zhou Melanie JScott Linsong Chen Dengming Lai Erica KFan Yuehua Li Qiang Wu Timothy RBilliar Mark AWilson Ping Wang Jie Fan | 2020 | Protein & Cell2020，11，2： | 2 |
| 3 | Novel Modular Multilevel Converter Against DC Faults for HVDC Applications显示文摘In view of the DC fault current isolation deficiency for the conventional half-bridge sub-module(HBSM)based modular multilevel converter(MMC),this paper presents an improved MMC topology.Both quasi reverse blocking submodules(QRBSMs)and current limit modules(CLMs)are employed to improve the DC fault handling capability for HVDC applications.This paper analyzes such a new converter configuration and operation principles.Then the DC pole-to-pole short circuit fault is taken into consideration for further study,as well as the fault current blocking mechanism and quantitative relationship between system electrical stress and key parameters.To validate the feasibility of the proposed topology and fault protection theory,extensive simulation results are demonstrated.It is concluded that the QRB-MMC can effectively block the fault current under DC fault condition.In addition,CLMs play an important role in further accelerating fault current attenuation.Moreover,QRB-MMC employs the original control and modulation strategies under normal operation conditions;thus,it further reduces the complexity of industry design. | Xiaofeng Yang Yao Xue Bowei Chen Zhiqin Lin Trillion Q.Zheng Yan Li | 2017 | CSEE Journal of Power and Energy Systems2017，3，2： | 2 |
| 4 | Cobalt tungsten phosphide with tunable W-doping as highly efficient electrocatalysts for hydrogen evolution reaction显示文摘It has been of interest in seeking electrocatalysts that could exercise equally high-efficient and durable hydrogen evolution upon nonselective electrolytes in both acidic and alkaline environments. Herein, we report a facile strategy to fabricate cobalt tungsten phosphides (CoxW2−xP2/C) hollow polyhedrons with tunable composition based on metal-organic frameworks (MOFs) template method. By the deliberate control of W doping, the synthesized catalyst with the composition of Co0.9W1.1P2/C is found to be able to achieve a current density of 10 mA·cm^(−2) at overpotentials of 35 and 54 mV in acidic and alkaline media, respectively. This combined electrochemical property stands atop the state-of-the-art electrocatalyst counterparts. To unveil the peculiar behavior of the structure, density functional theory (DFT) calculation was implemented and reveals that the surface W-doping facilitates the optimization of hydrogen absorption free energy (ΔGH*) as well as the thermodynamic and kinetics barriers for water dissociation, which is coupled with the hollow structure of Co-W phosphides, leading to the prominent HER catalytic performance. | Bowei Zhang Chaojiang Li Jun Hu Dongdong Peng Kang Huang Junsheng Wu Zhong Chen Yizhong Huang | 2021 | Nano Research2021，14，11： | 1 |
| 5 | AgPdCo hollow nanospheres electrocatalyst with high activity and stability toward the formate electrooxidation显示文摘The widespread commercial application of direct formate fuel cell(DFFC)is limited by the lack of efficient electrocatalysts for the formate oxidation reaction(FOR).AgPdCo hollow nanospheres(H-NSs)with jagged surfaces are successfully synthesized via a facile method involving the wet-chemical synthesis of AgPdCo nanospheres(NSs)and galvanic replacement reaction between Pd salt and AgPdCo NSs.Surpassing Ag_(30)Pd_(69)Co_(1) NSs and most of previously reported electrocatalysts,Ag_(9)Pd_(90)Co_(1) H-NSs exhibit extremely high FOR activity with a peak current density of 3.08 A·mg_(Pd)^(−1).Apart from the competitive activity,Ag_(9)Pd_(90)Co_(1) H-NSs show greatly improved chronoamperometric and cycling stability,whereby the current density retains about 0.24 A·mg_(Pd)^(−1) after 3,600 s electrocatalysis and the mass activity maintains 54.06%of the initial value after 500 cycles.The unique hollow nanosphere and synergistic effect are responsible for the enhanced activity and stability.This study will provide new clues for the development of outstanding electrocatalysts. | Qiao Wang Fuyi Chen Quan Tang Longfei Guo Tao Jin Bowei Pan Junpeng Wang Zhen Li Bo Kou Weiqi Bian | 2021 | Nano Research2021，14，7： | 1 |
| 6 | A failure criterion for shale considering the anisotropy and hydration based on the shear slide failure model显示文摘A failure criterion fully considering the anisotropy and hydration of shale is essential for shale formation stability evaluation.Thus,a novel failure criterion for hydration shale is developed by using Jaeger’s shear failure criterion to describe the anisotropy and using the shear strength reduction caused by clay minerals hydration to evaluate the hydration.This failure criterion is defined with four parameters in Jaeger’s shear failure criterion(S_(1),S_(2),a andφ),three hydration parameters(k,ω_(sh)andσ_(s))and two material size parameters(d and l0).The physical meanings and determining procedures of these parameters are described.The accuracy and applicability of this failure criterion are examined using the published experimental data,showing a cohesive agreement between the predicted values and the testing results,R^(2)=0.916 and AAREP(average absolute relative error percentage)of 9.260%.The error(|D_(p)|)is then discussed considering the effects ofβ(angle between bedding plane versus axial loading),moisture content and confining pressure,presenting that|Dp|increases whenβis closer to 30°,and|D_(p)|decreases with decreasing moisture content and with increasing confining pressure.Moreover,|D_(p)|is demonstrated as being sensitive to S1and being steady with decrease in the data set whenβis 0°,30°,45°and 90°. | Qiangui Zhang Bowei Yao Xiangyu Fan Yong Li Nicholas Fantuzzi Tianshou Ma Yufei Chen Feitao Zeng Xing Li Lizhi Wang | 2023 | International Journal of Mining Science and Technology2023，33，4： | 1 |

| 8 | Role of long non-coding RNAs in normal and malignant hematopoiesis显示文摘Long non-coding RNAs(lncRNAs)are defined as a class of nonprotein-coding transcripts greater than 200 nucleotides in length,which have diverse functions in development and diseases including hematopoiesis.Recent advances have revealed that lncRNAs regulate hematopoietic development at almost every stage,including differentiation of the myelocyte,lymphocyte,and erythrocyte.Abnormal regulation of the lncRNAs may block aspects of blood development,which can lead to different types of hematopoietic disorders.These findings highlight the role of lncRNAs as potential therapeutic tools in malignant hematopoiesis.In this review,we summarize recent progress in the study of functional lncRNAs associated with blood development,as well as dysregulated lncRNAs involved in diverse blood diseases by interacting with crucial susceptibility genes in different pathways.In addition,we discuss genome-wide studies on lncRNAs,which are helpful for genome screening and in-depth functional study of lncRNAs associated with blood development and disease. | WEI PanPan HAN BoWei CHEN YueQin | 2013 | Science China(Life Sciences)2013，56，10： | 1 |
| 9 | In vitro crevice corrosion of biodegradable magnesium in different solutions显示文摘Magnesium(Mg)is a promising biomedical metal because of its biodegradability.The crevice between tissue and Mg implant can not be neglected in some implantation sites due to inducing crevice corrosion of Mg.In this paper,a new single mold was designed to build the in vitro experimental setup and four kinds of solutions,i.e.the deionized water(DW),the 0.9 wt.%sodium chloride solution(NaCl),the phosphate buffer saline(PBS)and the modified simulated body fluid(m-SBF)were used to explore necessary factors of crevice corrosion in Mg.It was observed that crevice corrosion in Mg sheets would occur in NaCl and PBS solution under 0.2,0.5 and 0.8 mm crevice thickness.And it was found that there were two necessary factors,i.e.chloride ion and crevice dimension,in crevice corrosion.For the high-purity Mg cannulated screws,crevice corrosion could occur inside tunnel when immersed in PBS. | Bowei Chen Hongliu Wu Ruibang Yi Wenhui Wang Haidong Xu Shaoxiang Zhang Hongzhou Peng Junwei Ma Haomiao Jiang Rui Zan Shuang Qiao Yu Sun Peng Hou Pei Han Jiahua Ni Xiaonong Zhang | 2020 | Journal of Materials Science & Technology2020，52，17： | 0 |
| 10 | A novel polymer-based nitrocellulose platform for implementing a multiplexed microfluidic paperbased enzyme-linked immunosorbent assay显示文摘Nitrocellose(NC)membranes,as porous paper-like substrates with high protein-binding capabilties,are very popular in the field of point-of-care immunoassays.However,generating robust hydrophobic structures in NC membranes to fabricate microfluidic paper-based analytical devices(μPADs)remains a great challenge.At present,the main method relies on an expensive wax printer In addition,NC membranes very easy to adhere during the printing process due to electrostatic adsorption.Herein,we developed a facile,fast and low-cost strategy to fabricateμPADs in NC membranes by screen-printing polyurethane acrylate(PUA)as a barrier material for defning flow channels and reaction zones.Moreover,hydrophobic barriers based on UV-curable PUA can resist various surfactant solutions and organic solvents that are generally used in immunoassays and biochemical reactions.To validate the feasibility of this PUA-based NC membrane for immunoassays in point-of-care testing(POCT),we further designed and assembled a rotational paperbased analytical device for implementing a multiplexed enzyme-linked immunosorbent assay(ELISA)in a simple manner.Using the proposed device under the optimal conditions,alpha fetoprotein(AFP)and carcinoembryonic antigen(CEA)could be identified,with limits of detection of 136 pg/mL and 174 pg/mL,respectively,which are below the threshold values of these two cancer biomarkers for clinical diagnosis.We believe that this reliable device provides a promising plaform for the diagnosis of disease based on ELISA or other related bioassays in limited setings or remote regions. | Dong Lin Bowei Li Longwen Fu Ji Qi Chunlei Xia Yi Zhang Jiadong Chen Jaebum Choo Lingxin Chen | 2022 | Microsystems & Nanoengineering2022，8，3： | 0 |
| 11 | Global methyl halide emissions from biomass burning during 2003-2021显示文摘Methyl halides(CH3Cl,CH3Br,and CH3I)are ozone-depleting substances.Biomass burning(BB)is an important source of methyl halides.The temporal variations and global spatial distribution of BB methyl halide emissions are unclear.Thus,global methyl halide emissions from BB during 2003e2021 were estimated based on satellite data.A significant decreasing trend(p<0.01)in global methyl halide emissions from BB was found between 2003 and 2021,with CH3Cl emissions decreasing from 302 to 220 Gg yr^(-1),CH3Br emissions decreasing from 16.5 to 11.7 Gg yr^(-1),and CH3I emissions decreasing from 8.9 to 6.1 Gg yr^(-1).From a latitudinal perspective,the northern high-latitude region(60e90N)was the only latitude zone with significant increases in BB methyl halide emissions(p<0.01).Based on an analysis of the drivers of BB methyl halide emissions,emissions from cropland,grassland,and shrubland fires were more correlated with the burned area,while BB emissions from forest fires were more correlated with the emissions per unit burned area.The non-BB emissions of CH3Cl increased from 4749 Gg yr^(-1)in 2003 to 4882 Gg yr^(-1)in 2020,while those of CH3Br decreased from 136 Gg yr^(-1)in 2003 to 118 Gg yr^(-1)in 2020(global total CH3I emissions are not available).The finding indicates that global CH3Cl and CH3Br emissions from sources besides BB increased and decreased during 2003e2020.Based on our findings,not only searching for unknown sources is important,but also re-evaluating known sources is necessary for addressing methyl halide emissions. | Xiaoyi Hu Di Chen Liting Hu Bowei Li Xinhe Li Xuekun Fang | 2023 | Environmental Science and Ecotechnology2023，，2： | 0 |

| 15 | Epigenetic modification associated with climate regulates betulin biosynthesis in birch显示文摘The Betula genus contains pentacyclic triterpenoid betulin known for its environmental adaptation and medicinal properties.However,the mechanisms underlying betulin biosynthesis responding to climate change remain unclear.In this study,the role of epigenetic modification(DNA methylation) in betulin biosynthesis was examined and how climatic factors influence it.Whole-genome bisulfite sequencing was performed for greenhouse-grown Chinese white birch(Betula platyphylla Sukaczev) treated with DNA methylation inhibitor zebularine(ZEB) and a natural birch population in Northeast China.ZEB treatment significantly affected the CHH methylation level of transposable elements and betulin content in a hormesis dose-dependent manner.The methylation and expression of bHLH9,a key transcriptional factor controlling betulin biosynthesis,were also consistently affected by ZEB treatment as a hormetic dose-response.In the natural population,there was a positive correlation between promoter methylation of bHLH9 and summer precipitation,while winter temperature was negatively correlated.Thus climate-dependent methylation of bHLH9 regulates the expression of downstream genes involved in betulin biosynthesis.This study highlights the role of environmental signals to induce epigenetic changes that result in betulin production,possibly helping to develop resilient plants to combat ongoing climate change and enhance secondary metabolite production. | Jiang Wang Bowei Chen Shahid Ali Tianxu Zhang Yu Wang He Zhang Lishan Wang Yonglan Zhang Linan Xie Tingbo Jiang Jing Yin Heike W.Sederoff Gaurav Zinta Ronald R.Sederoff Yuhua Li Qingzhu Zhang | 2023 | Journal of Forestry Research2023，34，1： | 0 |

| 17 | Effects of plant growth regulators on the rapid proliferation of shoots and root induction in the Chinese traditional medicinal plant Atractylodes macrocephala显示文摘We developed an efficient plant regeneration protocol for rapidly propagating Atractylodes macrocephala Koidz,an important traditional Chinese medicinal plant,via shoot organogenesis.Shoot multiplication was induced on Murashige-Skoog(MS)medium supplemented with various concentrations of N-phenyl-N-1,2,3-thidiazol-5-ylurea(TDZ),6-benzylaminopurine(BA)andα-naphthaleneacetic acid(NAA).Rooting was induced on half-strength MS medium supplemented with NAA and indolebutyric acid(IBA).The maximum mean number of shoots(5.61)was obtained from a single explant by the combined effect of 1.08μmol/L NAA and 2.25μmol/L TDZ.The longest roots and a minimum number of roots were produced when they were cultured in a medium without plant growth regulators.The shortest roots and the largest number of roots were observed in the medium supplemented with 2.7μmol/L NAA. | Bizeng MAO Bowei HE Zaiming CHEN Bingliang WANG Huifeng PAN Debao LI | 2009 | Frontiers in Biology2009，4，2： | 0 |
| 18 | Preparation and Gas Sensing Performance of Hierarchical Porous ZnO-based Materials with Sunflower Rods as a Biological Template显示文摘A graded porous structure SnO2/ZnO composite was prepared with sunflower rods as a biological template. The prepared samples were subjected to phase analysis by scanning electron microscopy(SEM), transmission electron microscopy(TEM), X-ray diffractiometry(XRD) and X-ray photoelectron spectroscopy(XPS).ZnO sample was a pure phase of hexagonal wurtzite, and the template had been completely removed. The surface of the sample presented a honeycomb-like structure of a sunflower rod template, which was formed by interconnecting the porous channels, and had a smaller average size and exhibited n-n heterojunction at tlie n-type ZnO interface. Compared with that of pure ZnO, the response of the hierarchical porous structure SnO2/ZnO composite to 100 mg/L w-butanol reached a maximiuTi of 40.61 at 240℃, about 2.7 times higher than that of pure ZnO. Its response time and recovery time are 6 and 3 s, respectively, which are also better than those of pure ZnO. SnO2/ZnO composite exhibits good gas selectivity, which is related to the improvement of the structure and the forming of n-n heterojunctions of the material. | WANG Bowei ZENG Qingrui CHEN Shu YUE Tongtong HAN Bing FENG Wei YANG Defeng | 2019 | Chemical Research in Chinese Universities2019，35，5： | 0 |
| 19 | In situ optical spectroscopic understanding of electrochemical passivation mechanism on sol–gel processed WO_(3) photoanodes显示文摘A prevailing understanding on electrochemical activation of photoelectrodes is that electrochemical treatment leads to increased charge carrier densities thereby improved photoelectrode performances.Contrary to this understanding,in this study enhanced photoactivity of WO_(3) photoanode upon electrochemical treatment is ascribed to an extraordinary mechanism of surface trap passivation.The associated mechanism is analyzed by in situ optical spectroscopy,using which the optical property changes of WO_(3) electrode during electrochemical treatment are monitored.The results suggest surface W^(5+)species,the origin of surface traps on WO_(3) photoanodes,are converted to W^(6+) ions by electrochemical treatment.This study demonstrates the particular ability of the electrochemical strategy to passivate surface traps of photoanodes,and also shows the advantages of in situ optical spectroscopy to investigate the real-time electronic structure variations of electrodes during electrochemical treatment. | Jianyong Feng Xin Zhao Bowei Zhang Zhong Chen Zhaosheng Li Yizhong Huang | 2022 | Journal of Energy Chemistry2022，31，8： | 0 |
| 20 | Recurring Real-Time Monitoring of Inflammations in Living Mice with a Chemiluminescent Probe for Hypochlorous Acid显示文摘Probes for in vivo imaging of hypochlorous acid(HOCl),one of the most important reactive oxygen species in innate immunity,are urgently needed to understand the pathogenesis of autoimmune and neuroinflammatory disorders.As a strong oxidant,HOCl could bleach near-infrared sensors and inactivate luciferase readily,making in vivo imaging overwhelmingly challenging.Via fine-tuning of a selective HOCl sensing moiety,HOCl stable spacer,and bright chemiluminescent scaffold,we have developed HOCl-CL-510 as a highly selective and sensitive probe for HOCl detection both in vitro and in vivo.In particular,we achieved recurring real-time monitoring of HOCl in both acute and chronic inflammation models in living mice,providing a new chemical tool for dynamic monitoring of disease development with reduced usage of experimental animals. | Sen Ye Bowei Yang Meiling Wu Zefeng Chen Jiangang Shen Doron Shabat Dan Yang | 2022 | CCS Chemistry2022，4，6： | 0 |
