| 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 |

| 3 | Spatial distribution of planktonic ciliates in the western Pacifc Ocean: along the transect from Shenzhen (China) to Pohnpei (Micronesia)显示文摘Planktonic ciliates have been recognized as major consumers of nano-and picoplankton in pelagic ecosystems,playing pivotal roles in the transfer of matter and energy in the microbial loop.However,due to the difculties in identifcation,the species composition of ciliate assemblages,especially for the small,fragile,and naked species that usually dominate the ciliate communities in the oceanic waters,remains largely unknown.In the present study,22 stations along the transect from Shenzhen(China)to Pohnpei(Micronesia)were sampled for the enumeration of picoplankton and nanofagellates.In addition,pigment analysis of major phytoplankton groups along with the measurements of environmental variables including temperature,salinity,and nutrients were also carried out.Ciliates were identifed at species level using quantitative protargol stain to reveal the species composition and their distribution patterns from of-shore to open ocean.Ciliate abundance was positively correlated with phosphate,silicate,and pico-sized pigmented eukaryotes(PPEs),whereas the biomass was closely related with PPEs,heterotrophic nanofagellates,and chlorophytes.The combination of silicate and pigmented nanofagellates was identifed as the major factor driving the ciliate community composition.The close relationship between silicate and ciliate abundance and community structure needs further validation based on more data collected from oceanic waters.Our study showed the necessity of using techniques that can reveal the community composition at higher taxonomic resolutions in future studies on ciliates. | Hungchia Huang Jinpeng Yang Shixiang Huang Bowei Gu Ying Wang Lei Wang Nianzhi Jiao Dapeng Xu | 2021 | Marine Life Science & Technology2021，3，1： | 2 |
| 4 | 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 |
| 5 | Studies on Surface Properties and Cell Adhesion Properties of BSA Modified DBM Scaffold显示文摘As a scaffold material for bone tissue engineering, demineralized bone matrix(DBM) has such a limited ability to load cells and growth factors that the surface of the DBM scaffold was modified with bovine serum albumin(BSA) with different concentrations to improve the protein stmcture and physicochemical properties of the scaffold surface so as to enhance the adhesion of the cells. And the appropriate BSA concentration was explored. Compared with DBM, the scaffold with BSA coating had a smaller pore size and a lower porosity, also, the degradation rate was accelerated and the hydrophilic property was improved. Cells adhesion was observed inside the DBM seaffold before and after it had been modified, and the BSA modified scaffold had a good cell compatibility. Wlien the concentration of BSA was 20 mg/mL, the adhesion ability of the cells to modified scaffold was significantly increased, and the cell proliferation was facilitated. | SUN Mengjie FENG Wei WANG Bowei HAN Bing ZOU Jundong YANG Chunying LIU Zhihui | 2019 | Chemical Research in Chinese Universities2019，35，4： | 1 |
| 6 | Tribological performance under different environments of Ti-C-N composite films for marine wear-resistant parts显示文摘The need for reducing the wear in mechanical parts used in the industry makes self-lubricant films one of the sustainable solutions to achieve long-term protection under different environmental conditions.The purpose of this work is to study the influence of C additions on the tribological behavior of a magnetron-sputtered TiN film in air,water,and seawater.The results show that the addition of C into the TiN binary film induced a new amorphous phase,and the films exhibited a dual phase of fcc(face-centered cubic)-TiN and amorphous carbon.The antifriction and wear-resistance properties were enhanced in air and water by adding 19.1at%C.However,a further increase in the C concentration improved anti-frictional properties but also led to higher wear rates.Although the amorphous phase induced microbatteries and accelerated the corrosion of TiN phases in seawater,the negative abrasion state was detected for all Ti-C-N films due to the adhesion of the tribocorrosion debris on the wear track. | Hongbo Ju Rui Zhou Jing Luan Ch Sateesh Kumar Lihua Yu Junhua Xu Junfeng Yang Bowei Zhang Filipe Fernandes | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，1： | 1 |

| 8 | Dynamic value iteration networks for the planning of rapidly changing UAV swarms显示文摘In an unmanned aerial vehicle ad-hoc network(UANET),sparse and rapidly mobile unmanned aerial vehicles(UAVs)/nodes can dynamically change the UANET topology.This may lead to UANET service performance issues.In this study,for planning rapidly changing UAV swarms,we propose a dynamic value iteration network(DVIN)model trained using the episodic Q-learning method with the connection information of UANETs to generate a state value spread function,which enables UAVs/nodes to adapt to novel physical locations.We then evaluate the performance of the DVIN model and compare it with the non-dominated sorting genetic algorithm II and the exhaustive method.Simulation results demonstrate that the proposed model significantly reduces the decisionmaking time for UAV/node path planning with a high average success rate. | Wei LI Bowei YANG Guanghua SONG Xiaohong JIANG | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，5： | 1 |
| 9 | Numerical Simulation of Coseismic Response and Its Mechanism of Well Water Temperature to Farfield Strong Earthquakes显示文摘Heat flow is inevitably accompanied by temperature change,thus,the water temperature coseismic response during earthquake activity should also obey the laws of thermodynamics.Taking the M S8.0 Wenchuan,Sichuan,China earthquake and the M9.0Tohoku,Japan earthquake as an example,and based on the data of water temperature coseismic responses observed in well ZK26 in Haikou,Hainan Province,China,we investigate the relationship between well water temperature change and heat transfer in the coseismic response process and the relevant thermodynamic mechanism by using the numerical simulation method for thermodynamic equations.Then,through forward modeling,we obtain several simulation curves of water temperature change in response to earthquakes along the well depth at different times.The simulated curves of water temperature change approximately fit the observed curves.Consequently,based on the variation of temperature,we find that the modes of well water temperature coseismic response( ascending,descending or stable) are related to factors such as the location of sensors,distribution and location of heat sources,the span between sensors and heat sources. | Gu Shenyi Liu Bowei Zhang Hui Liu Yang Xie Xiaojing Ye Xiangding | 2013 | Earthquake Research in China2013，27，3： | 1 |
| 10 | Laser-Induced Recoverable Fluorescence Quenching of Perovskite Films at a Microscopic Grain Scale显示文摘Understanding the fundamental properties of metal-halide perovskite materials is driving the development of novel optoelectronic applications.Here,we report the observation of a recoverable laser-induced fluorescence quenching phenomenon in perovskite films with a microscopic grain-scale restriction,accompanied by spectral variations.This fluorescence quenching depends on the laser intensity and the dwell time under Auger recombination dominated conditions.These features indicate that the perovskite lattice deformation may take the main responsibility for the transient and show a new aspect to understand halide perovskite photostability.We further modulate this phenomenon by adjusting the charge carrier recombination and extraction,revealing that efficient carrier transfer can improve the bleaching resistance of perovskite grains.Our results provide future opportunities to attain high-performance devices by tuning the perovskite lattice disorder and harvesting the energetic carriers. | Yuren Xiang Yameng Cao Wenqiang Yang Rui Hu Sebastian Wood Bowei Li Qin Hu Fan Zhang Jujie He Mozhgan Yavari Jinlai Zhao Yunlong Zhao Jun Song Junle Qu Rui Zhu Thomas P.Russell S.Ravi P.Silva Wei Zhang | 2022 | Energy & Environmental Materials2022，5，4： | 0 |

| 12 | Secondary phase precipitate-induced localized corrosion of pure aluminum anode for aluminum–air battery显示文摘Understanding the influence of purities on the electrochemical performance of pure aluminum(Al)in alkaline media for Al–air batteries is significant.Herein,we comprehensively investigate secondary phase precipitate(SPP)-induced localized corrosion of pure Al in NaOH solution mainly based on quasi-in-situ and cross-section observations under scanning electron microscopy coupled with finite element simulation.The experimental results indicate that Al–Fe SPPs appear as clusters and are coherent with the Al substrate.In alkaline media,Al–Fe SPPs exhibit more positive potentials than the substrate,thus aggravating localized galvanic corrosion as cathodic phases.Moreover,finite element simulation indicates that the irregular geometry coupled with potential difference produces the non-uniform current density distribution inside the SPP cluster,and the current density on the Al substrate gradually decreases with distance. | Bowei Zhang Hezu Wang Yan Su Wenguang Yang Xuelong Hao Zequn Zhang Fengqin Wang Wei Xue Junsheng Wu | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，5： | 0 |

| 14 | Facile solution-processed molybdenum oxide as hole transporting material for efficient organic solar cell显示文摘The large energy barrier in hole extraction still remains a great challenge in developing hole transporting layer (HTL) materials for organic solar cells (OSCs).Thus,solution-processed HTL materials with excellent hole collection ability and good compatibility with large-area processing technique are strongly desired for OSCs.Herein,we developed a cost-effective and solution-processed MoO_(3)HTL for efficient OSCs.By adding a small amount of glucose as reducing reagent into the ammonium molybdate precursor solution,a deeply n-doped MoO_(3),namely G:Mo,was prepared through the sol–gel method.Compared to pristine MoO_(3),the conductivity of G:Mo was enhanced by two orders of magnitude,which greatly improved the hole collection ability of the HTL.OSCs with G:Mo can exhibit comparable PCE to the PEDOT:PSS device.Using PBDB-TF:BTP-eC9 as the active layer,a PCE of 17.1%is obtained for the device,which is the highest PCE value for OSC using a solution-processed MoO_(3)HTL.More importantly,G:Mo is well compatible with the blade-coating processing.The OSC using a blade-coated G:Mo showed almost no PCE loss as compared to the device with spin-coated G:Mo HTL.The results from this work indicate that G:Mo is a promising HTL material for the practical production of OSCs. | Qian Kang Chenyi Yang Bowei Xu Jianhui Hou | 2022 | Journal of Energy Chemistry2022，31，6： | 0 |
| 15 | Solution-Processed Silver Nanowire as Flexible Transparent Electrodes in Organic Solar Cells显示文摘Organic solar cells(OSCs)have attracted much attention due to their advantages in fabricating flexible and semi-transparent devices.Especially,the light weight,flexibility and spectral adjustability make OSCs superior to silicon,perovskite and other thin film based solar cells in applications of integrated photovoltaic devices and wearable electronics.In flexible and semi-transparent OSCs,transparent conducting electrodes(TCEs)play a key role in obtaining high performances.Among various TCEs,silver1 n anowire(AgNW)has become a promisi ng can didate due to its low sheet resistance,high optical transparency,excellent mechanical flexibility and solution processability.In this article,we review the recent advances in AgNW-based TCEs and their applications in the field of OSCs.Firstly,we introduce the general properties of AgNW including optoelectronic and mechanical characteristics.Secondly,the preparation methods of AgNW are discussed,along with some approaches on the optimization of AgNW to overcome the shortcomings of TCEs.Thirdly,we discuss the applications of AgNW as TCEs in fabricating flexible and semi-transparent OSCs,including the use of AgNW as bottom and top electrodes.Finally,we point out the challenges in AgNW-based TCEs and suggest several guidelines for preparing AgNW so as to meet the demands for the practical use of OSCs. | Yi Yang Bowei Xu Jianhui Hou | 2021 | Chinese Journal of Chemistry2021，39，8： | 0 |

| 17 | Selection of specific nanobodies against peanut allergen through unbiased immunization strategy and the developed immuno-assay显示文摘Peanut allergy is considered to be a major health issue with global effects.To date,no effective curative approach has been applied for the therapy of the anaphylaxis resulting from the peanut allergens.The accurate and effective detection methods for the surveillance of allergens in food are still the primary strategies to avoid allergic diseases.In this study,nanobodies(Nbs)derived from the Heavy-Chain only Antibodies(HCAbs)were selected against the general peanut protein extract through the unbiased strategy to facilitate the development of the sandwich ELISA for the detection and surveillance of peanut allergen contamination.The target antigen of the selected Nb was identified as peanut allergen Ara h 3,and a cross-reaction was observed with the member of Gly 1 from the Ara h 3 family.The applicability of the self-paired Nb P43 on the establishment of the immuno-assay was verified.A sandwich ELISA against peanut allergen was developed,which reached a linear range of 0.2-10.6μg/mL,and a limit of detection of 53.13 ng/mL. | Yaozhong Hu Chuan Zhang Jing Lin Yi Wang Sihao Wu Ying Sun Bowei Zhang Huan Lv Xuemeng Ji Yang Lu Shuo Wang | 2023 | Food Science and Human Wellness2023，12，3： | 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 | Highly Stable Organic Solar Cells Based on an Ultraviolet-Resistant Cathode Interfacial Layer显示文摘Although the photovoltaic efficiency of organic solar cells(OSCs)has exceeded 17%,poor lifetime excludes OSCs from practical use.In particular,UV rays in sunlight may cause the decomposition of organic photovoltaic materials,which has been proved to be the main reason for the efficiency decay.At present,there is still no effective approach to substantially improve the device stability.Herein,we fabricate a highly efficient OSC with exceptional stability under sunlight illumination by incorporating a UV-resistant cathode interlayer(CIL),namely(sulfobetaine-N,Ndimethylamino)propyl naphthalene diimide(NDI-B).NDI-B was designed and synthesized based on the naphthalene diimide(NDI)unit,thereby exhibiting excellent capability of electron collection.Moreover,NDI-B shows strong absorption in the UV region and has good UV resistance.Devices using NDI-B as a CIL exhibited a photovoltaic efficiency of 17.2%,representing the state-of-the-art photovoltaic performance of OSCs.Notably,the NDI-B-modified OSC exhibited a T80 of over 1800 h under full-sun AM 1.5 G illumination(100 mW cm^(−2)),which represents the best stability for OSCs.We demonstrate that the unique ability of the NDI-B interlayer to convert UV light to an additional photocurrent can effectively protect photovoltaic materials from UV-induced decomposition,which is the key to obtain high OSC stability under operational conditions. | Qing Liao Qian Kang Yi Yang Zhong Zheng Jinzhao Qin Bowei Xu Jianhui Hou | 2022 | CCS Chemistry2022，4，3： | 0 |
| 20 | Microstructural evolution and strengthening mechanism of Al–Mg alloys with fine grains processed by accumulative continuous extrusion forming显示文摘In this work,the mechanical properties and strengthening mechanisms induced by microstructural evolution in a rheo-extruded 5087 alloy processed via accumulative continuous extrusion forming(ACEF)were investigated.Electron back-scattered diffraction(EBSD)and transmission electron microscopy(TEM)were utilized to characterize the microstructure of the alloy subjected to ACEF with various passes.The grain refinement caused by continuous dynamic recrystallization(CDRX)was discussed.The results demonstrated that after 3 passes of ACEF,there was a significant grain refinement effect on the alloy,and the average grain size decreased from 45.6μm to 2.5μm;the ultimate tensile strength(UTS)and yield strength(YS)of the alloy increased to 362.8 MPa and 234.6 MPa,respectively.Dislocation cells/walls generated during deformation promoted the formation of low angle grain boundaries(LAGBs).The accumulative strain accelerated the transformation of LAGBs to high angle grain boundaries(HAGBs).Dislocation pile-up enhanced the driving force of CDRX,and nano-sized Al_6(Mn,Fe)phases at the grain boundaries inhibited the growth of grains due to the pinning effect.Based on the quantitative estimation,dislocation strengthening and grain boundary strengthening dominated the enhancement in YS of the ACEFed alloy. | Bowei Yang Yu Wang Minqiang Gao Changfeng Wang Renguo Guan | 2022 | Journal of Materials Science & Technology2022，，33： | 0 |
