| 1 | Particle size distribution and characteristics of polycyclic aromatic hydrocarbons during a heavy haze episode in Nanjing,China显示文摘A heavy haze episode caused by agricultural burning occurred in Nanjing from November 7 to November8,2009.PM_(10) samples were collected on normal and hazy days from November 1 to November 14,2009 at both city and suburban sites of Nanjing.Sixteen PAHs were measured during the day and at night.The results show that the concentrations of the particles were as high as 579.55 and 573.43 μg/m^3 during the haze episode at the city and suburban sites,respectively,3-4 times higher than those on a normal day.The proportions of fine particles during the haze episode were also higher than those on a normal day.The changes in the concentrations of PAHs were in accordance with the concentrations of the particles.Highmolecular-weight PAHs composed approximately 80% of the total PAHs on normal days and during the haze episode.The concentration of PAHs in fine fractions significantly increased during the haze episode,and this increase was most obvious at night at the city site.The proportion of total carcinogenic PAHs in fine particles was relatively high during the haze episode at both sampling sites,particularly at night at the city site. | Qingzi Meng Shuxian Fan Jiabao He Jian Zhang Yu Sun Yue Zhang Fan Zu | 2015 | Particuology2015，13，1： | 16 |
| 2 | Biomaterial-based strategies for maxillofacial tumour therapy and bone defect regeneration显示文摘Issues caused by maxillofacial tumours involve not only dealing with tumours but also repairing jaw bone defects.In traditional tumour therapy,the systemic toxicity of chemotherapeutic drugs,invasive surgical resection,intractable tumour recurrence,and metastasis are major threats to the patients’lives in the clinic.Fortunately,biomaterial-based intervention can improve the efficiency of tumour treatment and decrease the possibility of recurrence and metastasis,suggesting new promising antitumour therapies.In addition,maxillofacial bone tissue defects caused by tumours and their treatment can negatively affect the physiological and psychological health of patients,and investment in treatment can result in a multitude of burdens to society.Biomaterials are promising options because they have good biocompatibility and bioactive properties for stimulation of bone regeneration.More interestingly,an integrated material regimen that combines tumour therapy with bone repair is a promising treatment option.Herein,we summarized traditional and biomaterial-mediated maxillofacial tumour treatments and analysed biomaterials for bone defect repair.Furthermore,we proposed a promising and superior design of dual-functional biomaterials for simultaneous tumour therapy and bone regeneration to provide a new strategy for managing maxillofacial tumours and improve the quality of life of patients in the future. | Bowen Tan Quan Tang Yongjin Zhong Yali Wei Linfeng He Yanting Wu Jiabao Wu Jinfeng Liao | 2021 | International Journal of Oral Science2021，13，1： | 9 |
| 3 | Surface modification with ionic liquid for efficient CsPbI2Br perovskite solar cells显示文摘The presence of numerous trap states on the perovskite surface severely affects the performance of inorganic CsPbI_(2)Br perovskite solar cells.Surface modification has been proven to be an effective strategy to passivate the surface trap states of CsPbI_(2)Br perovskite.However,most modifiers behave high volatility and insulation,not enough to further develop the CsPbI_(2)Br solar cells.Herein,an ionic liquid of 1-viny-3-propionate ethyl imidazolium chloride([PEVIM]Cl)is applied to modify the CsPbI_(2)Br film surface,yielding a compact film with enhanced crystallinity.The surface trap states of CsPbI_(2)Br film are effectively passivated via the interaction between carbonyl group of[PEVIM]Cl and uncoordinated metal cations of CsPbI_(2)Br perovskite,leading to charge recombination suppression and charge transport enhancement.Consequently,the power conversion efficiency(PCE)of[PEVIM]Cl modified CsPbI_(2)Br device is obviously enhanced from 12.49% to 14.19% with an improved open-circuit voltage of 1.160 V.Moreover,the non-encapsulated device presents excellent thermal stability,still maintaining 91%PCE when heated at 85℃ in nitrogen atmosphere for 360 h.Meanwhile,the non-encapsulated device degrades only 11% PCE after stored at 50% relative humidity for 960 h.This simple and efficient approach provides a promising direction to fabricate high-efficiency and stable inorganic perovskite devices. | Xingyu Pu Jian Han Shuangjie Wang Hui Zhou Qi Cao Jiabao Yang Ziwei He Xuanhua Li | 2021 | Journal of Materiomics2021，7，5： | 3 |

| 5 | Tailoring the mercaptan ligands for high performance inverted perovskite solar cells with efficiency exceeding 21%显示文摘Interface passivation engineering has been recognized as an effective way to simultaneously contribute to the optoelectronic characteristic and stability of perovskite solar cells(PSCs). Herein, a p-conjugated dual-ligand 1,4-phenylmercaptan(PHMT) is explored to rationally tailor the surface of perovskite film.The experimental and theoretical results show that the PHMT presents planar structure and obvious electron delocalization characteristics, which allow it to anchor on the surface of perovskite with a certain orientation, thereby promoting the transport of interface charge. Moreover, the two sulfhydryl groups in PHMT reduce the trap density of the perovskite film by passivating under-coordinated lead ions.Consequently, the PHMT-modified inverted device based on MAPbI_(3)(MA: methylammonium) achieves enhanced efficiency from 18.11%(control) to 21.11%, along with the ambient stability up to 3500 h.After being placed at 85 °C for 500 h or illuminated for 600 h, the modified device remains over 89%or 86% of initial efficiency. This discovery opens a new window for the choice of passivators to improve the performance of PSCs. | Shuangjie Wang Ziwei He Jiabao Yang Tongtong Li Xingyu Pu Jian Han Qi Cao Bingyu Gao Xuanhua Li | 2021 | Journal of Energy Chemistry2021，30，9： | 1 |
| 6 | Surface Yielding of Metals by X-ray Diffraction显示文摘Surface yielding of metallic material was measured with strain gage and X-ray diffraction methods.The results show that.when the residual stress in the transverse direction is involved,the surface yieldstrength should be evaluated with biaxial Mises criterion.For a medium carbon high strength steel,the yield strength of the bulk material is 581 MPa and the surface yield strengths for 0.05% and0.1%plastic strain are about 436 MPa and 463 MPa respectively.The 0.05% yield strength willapproximately increase to 788 MPa after shot peening.In the early stage of plastic deformation,strain hardening in the surface layer is quite different from that of the bulk sample. | Xiuying GAI Jiabao LI Zengqiao KANG State Key Lab.for Fatigue and Fracture of Materials,Institute of Metal Research,Academia Sinica,Shenyang,110015,ChinaJiawen HE Xi’an Jiaotong University,Xi’an,710049,China | 1993 | Journal of Materials Science & Technology1993，9，3： | 0 |
| 7 | Skeleton Keypoints Extraction Method Combined with Object Detection显示文摘Big data is a comprehensive result of the development of the Internet of Things and information systems.Computer vision requires a lot of data as the basis for research.Because skeleton data can adapt well to dynamic environment and complex background,it is used in action recognition tasks.In recent years,skeleton-based action recognition has received more and more attention in the field of computer vision.Therefore,the keypoints of human skeletons are essential for describing the pose estimation of human and predicting the action recognition of the human.This paper proposes a skeleton point extraction method combined with object detection,which can focus on the extraction of skeleton keypoints.After a large number of experiments,our model can be combined with object detection for skeleton points extraction,and the detection efficiency is improved. | Jiabao Shi Zhao Qiu Tao Chen Jiale Lin Hancheng Huang Yunlong He d Yu Yang | 2022 | Journal of New Media2022，4，2： | 0 |
| 8 | Surface passivation by multifunctional carbon dots toward highly efficient and stable inverted perovskite solar cells显示文摘Interfacial imperfections between the perovskite layer and the electron transport layer(ETL)in perovskite solar cells(PSCs)can lead to performance loss and negatively influence long-term operational stability.Here,we introduce an interface engineering method to modify the interface between perovskite and ETL by using multifunctional carbon dots(CDs).C=O in the CDs can chelate with the uncoordinated Pb2+in the perovskite material,inhibit interfacial recombination,and enhance the performance and stability of device.In addition,–OH in CDs forms hydrogen bonds with I-and organic cation in perovskite,inhibiting light-induced I2release and organic cation volatilization,causing irreversible degradation of perovskite films,thereby enhancing the long-term operational stability of PSCs.Consequently,we achieve the champion inverted device with an efficiency of 24.02%.The CDs-treated PSCs exhibit high operational stability,and the maximum power point tracking only attenuates by 12.5%after 1000 h.Interfacial modification engineering supported by multifunctional quantum dots can accelerate the road to stable PSCs. | Qi Cao Yixin Zhang Xingyu Pu Junsong Zhao Tong Wang Kui Zhang Hui Chen Xilai He Jiabao Yang Cheng Zhang Xuanhua Li | 2023 | Journal of Energy Chemistry2023，，11： | 0 |

| 11 | Deciphering the effect of sodium dodecylbenzene sulfonate on up-flow anaerobic sludge blanket treatment of synthetic sulfate-containing wastewater显示文摘In this study,the effects of organic sulfur on anaerobic biological processes were investigated by operating two up-flow anaerobic sludge blanket(UASB)reactors with sodium dodecylbenzene sulfonate(SDBS)as a representative of organic sulfur.The results indicated that the specific methanogenic activity(SMA)and chemical oxygen demand(COD)removal efficiency of R2(with SDBS added)were higher than those of R1(without SDBS)when the COD/SO_(4)^(2−)ratio was above 5.0.However,when the COD/SO_(4)^(2−)ratio was lower than 5.0,the sulfate reduction efficiency of R2 was higher than that of R1.These results and the observed SDBS transformation efficiency in anaerobic reactors indicate that low concentrations of SDBS accelerate methane production and the continuous accumulation of SDBS does not weaken the reduction of sulfate.Similarly,the calculated electron flux for a COD/SO_(4)^(2−)ratio of 1.0 indicates that the utilization intensity of electrons by sulfate-reducing bacteria(SRB)in R2 was 36.48%higher than that of SRB in R1 and exceeded that of methane-producing archaea(MPA)under identical working conditions.Moreover,the addition of SDBS in R2 made sulfidogenesis the dominant reaction at low COD/SO_(4)^(2−),and Methanobacterium and Methanobrevibacter with H_(2)/CO_(2)as the substrate and Desulfomicrobium were the dominant MPA and SRB,respectively.However,methanogenesis was still the dominant reaction in R1,and Methanosaeta with acetic acid as the substrate and Desulfovibrio were the dominant MPA and SRB,respectively. | Ruijie Li Mengmeng Zhou Shilong He Tingting Pan Jing Liu Jiabao Zhu | 2021 | Frontiers of Environmental Science & Engineering2021，15，5： | 0 |
