| 1 | Ultrasensitive skin‐like wearable optical sensors based on glass micro/nanofibers显示文摘Electronic skin,a class of wearable electronic sensors that mimic the functionalities of human skin,has made remarkable success in applications including health monitoring,human-machine interaction and electronic-biological interfaces.While electronic skin continues to achieve higher sensitivity and faster response,its ultimate performance is fundamentally limited by the nature of low-frequency AC currents.Herein,highly sensitive skin-like wearable optical sensors are demonstrated by embedding glass micro/nanofibers(MNFs)in thin layers of polydimethylsiloxane(PDMS).Enabled by the transition from guided modes into radiation modes of the waveguiding MNFs upon external stimuli,the skin-like optical sensors show ultrahigh sensitivity(1870 k·Pa^-1),low detection limit(7 mPa)and fast response(10μs)for pressure sensing,significantly exceeding the performance metrics of state-of-the-art electronic skins.Electromagnetic interference(EMI)-free detection of high-frequency vibrations,wrist pulse and human voice are realized.Moreover,a five-sensor optical data glove and a 2×2-MNF tactile sensor are demonstrated.These initial results pave the way toward a new category of optical devices ranging from ultrasensitive wearable sensors to optical skins. | Lei Zhang Jing Pan Zhang Zhang Hao Wu Ni Yao Dawei Cai Yingxin Xu Jin Zhang Guofei Sun Liqiang Wang Weidong Geng Wenguang Jin Wei Fang Dawei Di Limin Tong | 2020 | Opto-Electronic Advances2020，3，3： | 12 |
| 2 | Effects of meteorological factors on the defoliation dynamics of the larch caterpillar(Dendrolimus superans Butler)in the Great Xing’an boreal forests显示文摘Larch caterpillars are widely distributed in the Great Xing’an boreal forests;however,the relationship between caterpillar defoliation dynamics and climatic factors is poorly understood.The aims of this study are to investigate the primary weather conditions that might influence forest defoliation and to identify the most important life stage of the larch caterpillar at which forest defoliation might be mitigated by incorporating more inhibitory influences from climatic factors.The life cycle of the larch caterpillar was partitioned into four stages and multiple linear regression and mixed effect models were combined with a relative weight analysis approach to evaluate the importance and influence of meteorological variables on defoliation dynamics.The results show that warmer temperatures in growing seasons and overwintering periods can increase the defoliation area,while rainy and humid growing seasons decrease the defoliation area.Total precipitation during the early instar larval period had the greatest power to explain the variance in defoliation dynamics and had a very strong inhibitory effect,followed by the accumulative temperatures of the late instar larval period which had a positive impact,and precipitation during the middle instar larval period which had a negative impact.Weather conditions during the early instar larval period had the greatest influence on the area defoliated and accounted for 40%of the explained variance.This study demonstrates that climatic warming and drying will increase the risk of larch caterpillar outbreaks in the Great Xing’an Mountains. | Lei Fang Yue Yu Guofei Fang Xu Zhang Zhijun Yu Xudong Zhang Ellen Crocker Jian Yang | 2021 | Journal of Forestry Research2021，32，6： | 3 |
| 3 | Corrosion Inhibition by Co-Immobilized Lysozyme and Lipase in Circulating Cooling Water System显示文摘The corrosion inhibition performance of co-immobilized lysozyme and lipase was investigated in a recirculating cooling water system. Four methods were carried out in co-immobilization, and the operating parameters were optimized by using the respond surface methodology(RSM). The corrosion inhibition performance of co-immobilized lipase and lysozyme was evaluated by weight loss measurements and electrochemical measurements. The results revealed that the optimal co-immobilization method should be the sequential immobilization of lysozyme and then lipase. The inhibition efficiency was 86.10% under the optimal co-immobilized conditions. Electrochemical data showed that co-immobilized lysozyme and lipase was a mixed-type inhibitor and the corrosion inhibition efficiency was 81%. | Liu Fang Lü Yucui Jiang Guofei Chen Xiaorui Sun Juan Zhao Chaocheng | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，2： | 3 |
| 4 | Surveillance of pine wilt disease by high resolution satellite显示文摘Pine wilt disease caused by the pinewood nematode Bursaphelenchus xylophilus has led to the death of a large number of pine trees in China.This destructive disease has the characteristics of bring wide-spread,fast onset,and long incubation time.Most importantly,in China,the fatality rate in pines is as high as 100%.The key to reducing this mortality is how to quickly find the infected trees.We proposed a method of automatically identifying infected trees by a convolution neural network and bounding box tool.This method rapidly locates the infected area by classifying and recognizing remote sensing images obtained by high resolution earth observation Satellite.The recognition accuracy of the test data set was 99.4%,and the remote sensing image combined with convolution neural network algorithm can identify and determine the distribution of the infected trees.It can provide strong technical support for the prevention and control of pine wilt disease. | Hongwei Zhou Xinpei Yuan Huanyu Zhou Hengyu Shen Lin Ma Liping Sun Guofei Fang Hong Sun | 2022 | Journal of Forestry Research2022，33，4： | 2 |

| 7 | Combined Use of Co-immobilized Lysozyme and Lipase and Chemical Inhibitors in Circulating Cooling Water System显示文摘In order to improve the stability and corrosion inhibition performance of bioenzyme, lipase and lsozyme were co-immobilized on the mesoporous molecular sieve MCM-41 by the adsorption method. Then the immobilized enzymes were combined with amino trimethylene phosphonic acid and polyaspartic acid to prevent corrosion caused by circulating cooling water. The weight-loss method and electrochemical techniques were used to evaluate the performance of composite inhibitors. The co-immobilized lysozyme and lipase achieved good inhibition effects. After they were combined with amino trimethylene phosphonic acid and polyaspartic acid, the corrosion inhibition properties were further improved. The inhibition efficiency was promoted to 94.4%. During the corrosion inhibition process, the immobilized enzymes played an important role. The addition of corrosion inhibitor could inhibit the anodic dissolution and cathodic hydrogen evolution process of carbon steel at the same time. The adsorption of co-immobilized lysozyme and lipase composite inhibitor on the steel surface was a joint action involving physical adsorption and chemical adsorption. | Jiang Guofei Chen Xiaorui Lu Xin Liu Fang Wang Yongqiang Zhao Chaocheng Sun Juan | 2018 | China Petroleum Processing & Petrochemical Technology2018，20，4： | 1 |

| 9 | Enhanced activity of ZnS(111) by N/Cu co-doping:Accelerated degradation of organic pollutants under visible light显示文摘High-efficiency photocatalysts are of great significance for the application of photocatalytic technology in water treatment.In this study,N/Cu co-doped ZnS nanosphere photocatalys(N/Cu-ZnS) is synthesized by a hydrothermal method for the first time.After doping,the tex ture of nanosphere becomes loose,the nanometer diameter is reduced,making the specific surface area of catalyst increased from 34.73 to 101.59 m^(2)/g.The characterization results show that more ZnS (111) crystal planes are exposed by N/Cu co-doping;the calculations of density functional theory show that N/Cu co-doping can increase the catalytic activity of the ZnS (111) crystal plane,enhance the adsorption capacity of (111) crystal plane to O_(2)and promote the generation of·O_(2)-.The energy levels of the introduced impurities can be hybridized with the energy levels of S and Zn at the top of valence band and the bottom o conduction band,which makes the band gap narrower,thus enhancing the absorption o visible light.Compared with pure ZnS,the degradation rates of 2,4-dichlorophenol (2,4-DCP and tetracycline (TC) by N/Cu-ZnS under visible light (>420 nm) are increased by 83.7 and51 times,respectively.In this research,a promising photocatalyst for photocatalytic degra dation of organic pollutants in wastewater is provided. | Guofei Jiang Benjie Zhu Junzhi Sun Fang Liu Yongqiang Wang Chaocheng Zhao | 2023 | Journal of Environmental Sciences2023，，3： | 0 |
| 10 | Antibacterial and Corrosion Inhibition Properties of SA-ZnO@ODA-GO@PU Super-Hydrophobic Coating in Circulating Cooling Water System显示文摘In order to solve the corrosion problem of circulating cooling water system,SA-ZnO@ODA-GO@PU super-hydrophobic coating was synthesized for pipeline protection.After hydrophobic modification,the contact angle(CA)of the coating was above 150°.The antibacterial ability of coating was essential for corrosion protection.SA-ZnO@ODA-GO can seriously damage the cell structure,make the cell content outflow,increase the leakage rate of protein,and make the bacteria unable to reach logarithmic growth phase within 24 h.The corrosion inhibition mechanism analysis of SA-ZnO@ODA-GO@PU coating indicated that the hydrophobic coating as a physical barrier can prevent the water molecules from entering the carbon steel and prevent the surface charge transfer. | Liu Fang Kong Can Li Wei Jiang Guofei Wang Xueyao | 2022 | China Petroleum Processing & Petrochemical Technology2022，24，1： | 0 |
| 11 | Hydrophobic and Magnetic Reduced Graphene Oxide Nanocomposite for Emulsified Oil Removal显示文摘Magnetic reduced graphene oxide(MRGO) nanocomposite was prepared by the chemical coprecipitation method and applied as adsorbent for removing emulsified oil from oily wastewater. SEM, TEM, XRD, FT-IR, VSM and other analytical methods were utilized to characterize the prepared MRGO. The adsorption performance of MRGO was evaluated under different initial adsorbate concentration, MRGO dosage, temperature, and pH value of the solution. The adsorption kinetics and isotherms were investigated. In addition, the MRGO repeatability was also tested. It was found that almost 65%of emulsified oil were removed by MRGO in the first 15 min. The MRGO adsorption capacity and efficiency for removal of adsorbate reached 335.85 mg/g and 92.52% within 60 min, respectively. The adsorption capacity reduced with an increasing MRGO dosage, while increased with the increase of emulsified oil concentration. The adsorption performance of MRGO in the alkaline environment was lower than that in the acidic environment. The adsorption data could well fit to the pseudosecondorder model. The Langmuir model could well describe the isotherm data. The MRGO adsorption capacity was still more than 236.1 mg/g at the sixth regeneration cycle. | Fan Fengtao Li Xufei Liu Fang Jiang Guofei Sui Linlin Zhao Chaocheng | 2017 | China Petroleum Processing & Petrochemical Technology2017，19，3： | 0 |
