| 1 | Fabrication of the Superhydrophobic Surface on Magnesium Alloy and Its Corrosion Resistance显示文摘The superhydrophobic surface was fabricated on the AZ31 alloy by the combination of the hydrothermal treatment method and post modification with stearic acid. The superhydrophobic surface showed a static water contact angle of 157.6°. The characteristics of the coatings were characterized by scanning electron microscopy(SEM), X-ray diffraction(XRD) and Fourier transform infrared spectroscopy(FTIR). The corrosion resistance of the superhydrophobic coatings was investigated by potentiodynamic polarization test and electrochemical impedance spectroscopy(EIS). The results revealed that the superhydrophobic coatings, characterized by petal-like structure significantly improved the corrosion resistance of the AZ31 alloy. | Fen Zhang Changlei Zhang Liang Song Rongchang Zeng Shuoqi Li Hongzhi Cui | 2015 | Journal of Materials Science & Technology2015，31，11： | 17 |
| 2 | Key CO_(2)capture technology of pure oxygen exhaust gas combustion for syngas-fueled high-temperature fuel cells显示文摘Integrated gasification fuel cells(IGFCs)integrating high-temperature solid oxide fuel cell technology with CO_(2)capture processes represents highly-efficient power systems with negligible CO_(2)emissions.Flame burning with pure oxygen is an ideal method for fuel cell exhaust gas treatment,and this report describes experimental and numerical studies regarding an oxy-combustor for treating the exhaust gas of a 10 kW IGFC system anode.The applied simulation method was verified based on experiments,and the key performance indices of the combustor were studied under various conditions.It was determined that 315 K was the ideal condensation temperature to obtain flame stability.Under these pure oxygen flame burning conditions,CO was almost completely converted,and the dry mole fraction of CO_(2)after burning was C 0.958 when there was up to 5%excess O_(2).Overall,5%excess O_(2)was recommended to maximize CO_(2)capture and promote other environmental considerations.Additionally,the optimal tangential fuel jet angle to control the liner temperature was approximately 25°.The total fuel utilization had to be high enough to maintain the oxygen flame temperature of the anode exhaust gas below 1800 K to ensure that the system was environmentally friendly.The results presented herein have great value for designing IGFCs coupled with CO_(2)capture systems. | Hanlin Wang Qilong Lei Pingping Li Changlei Liu Yunpeng Xue Xuewei Zhang Chufu Li Zhibin Yang | 2021 | International Journal of Coal Science & Technology2021，8，3： | 3 |
| 3 | In-Situ Chemosynthesis of ZnO Nanoparticles to Endow Wood with Antibacterial and UV-Resistance Properties显示文摘Hybrid wood materials have attracted considerable attention because they have combined advantages of both wood and inorganic compounds. This work investigated the microstructural morphology, thermal stability, ultraviolet(UV) stability, and antibacterial property of composites made from wood/ZnO hybrid materials through a facile in-situ chemosynthesis methods. The X-ray diffraction(XRD) and thermogravimetric analysis(TGA) results indicated that the synthesized ZnO particles had an average grain size of about 10.8 nm. The scanning electron microscopy(SEM) observations showed that ZnO nanoflowers self-assembled with nanosheets were presented in wood cell lumens and increased with increasing Zn^(2+)concentrations. ZnO nanoparticles were also generated in the wood cell wall, which was confirmed by the results of energy-dispersive spectroscopy(EDS). The TGA tests also indicated that the thermal stability of wood/ZnO hybrid materials was improved after the formation of ZnO inorganic particles. Finally, the results of antibacterial efficacy tests and UV resistance tests revealed that ZnO nanoparticles showed a promising future as antimicrobial agents against Escherichia coli(E.coli) and UV resistance agents for wood protection. | Youming Dong Yutao Yan Huandi Ma Shifeng Zhang Jianzhang Li Changlei Xia Sheldon Q.Shi Liping Cai | 2017 | Journal of Materials Science & Technology2017，33，3： | 2 |

| 5 | Catalytic performance of Pt/HY-β in n-octane hydroisomerization显示文摘A bifunctional catalyst Pt/HY-β was prepared from a bimicroporous composite zeolite Y-β. Characterization results showed that the specific surface area,pore volume,and acid amount of the catalyst Pt/HY-β all decreased compared to the original zeolite.The catalytic performance of this catalyst in n-octane hydroisomerization was investigated in a fixed bed stainless steel tubular reactor.The results showed that at a hydrogen/n-octane volume ratio of 1000,pressure of 0.6 MPa,temperature of 230°C and LHSV of 3 h-1,the conversion of n-octane,yield of liquid,hydrocracking rate and yield of iso-octane were 52.32%,88.66%,12.60%,39.51%,respectively. | Jin Changlei MA Bo Zhang Xiwen Ling Fengxiang Zhang Zhizhi Qin Bo | 2009 | Petroleum Science2009，6，3： | 1 |

| 7 | Suppression of deep‑level traps via semicarbazide hydrochloride additives for high‑performance tin‑based perovskite solar cells显示文摘Tin perovskites with exemplary optoelectronic properties ofer potential application in lead-free perovskite solar cells.However,Sn vacancies and undercoordinated Sn ions on the tin perovskite surfaces can create deep-level traps,leading to nonradiative recombination and absorption of nucleophilic O_(2)molecules,impeding further device efciency and stability.Here,in this study,a new additive of semicarbazide hydrochloride(SEM-HCl)with a N–C=O functional group was introduced into the perovskite precursor to fabricate high-quality flms with a low concentration of deep-level trap densities.This,in turn,serves to prevent undesirable interaction between photogenerated carriers and adsorbed oxygen molecules in the device’s operational environment,ultimately reducing the proliferation of superoxide entities.As the result,the SEM-HCl-derived devices show a peak efciency of 10.9%with improved device stability.These unencapsulated devices maintain almost 100%of their initial efciencies after working for 100 h under continuous AM1.5 illumination conditions. | Wenbo Jia Yi Jing Han Zhang Baoyan Tian Huabo Huang Changlei Wang Ligang Xu | 2023 | Frontiers of Optoelectronics2023，16，4： | 0 |
