    Effect of Tilted Nanostructures on Anisotropic Wetting Behavior on PET Surfaces by Oxygen Plasma Modification by WANG Yitian, LI Yupeng, HUO Lei, LEI Mingkai

    Published 2024-12-01
    “…In order to improve the wettability of polymer surfaces, oxygen plasma modification technology was used to treat the surface of polyethylene terephthalate (PET) under the condition of 200 W for 90 min using sample holders with inclination angles of 30°, 45° and 60°.The nanostructures with tilt angles and lengths of 32.5° and 2.36 μm,45.2° and 2.15 μm,59.5° and 2.00 μm were prepared, respectively.Anisotropic wetting of liquid droplets and directional flow behavior of liquid were studied on the PET surfaces after modified by plasma.Additionally,the direction opposite to the tilted nanostructure was referred to as the Y+direction, the direction along the tilted nanostructure was referred to as the Y- direction, and the direction perpendicular to Y± was referred to as the X± direction.Results showed that the contact angle of the droplet on the PET surfaces modified by plasma decreased, and the wetting length increased with the increase of inclination angle of the sample holders.Meanwhile, the static contact angle of the droplet in the X± direction was greater than that in the Y± direction,and the wetting length in the X± direction was smaller than that in the Y± direction.Continuous water injection was carried out on the PET surfaces modified by plasma.The droplets were pinned in the Y- direction and flowed in the Y+direction.Furthermore, the average flow velocities of droplets on the plasmamodified surface at 30°,45° and 60° inclination angles were 0.017 0,0.021 0 and 0.022 7 mm/s,respectively.Among them,the droplets on the PET surfaces after modified by plasma at 60° inclination angle had a flow velocity of 2.39 times that of the original surfaces in the Y+direction.…”

    Decadal Variation Characteristics of Surface Wind Speed in Northwest China during 1979 -2020 by Yong WANG, Zihan ZHOU, Chenghai WANG, Dong XIAO, Haojun QIN, Wubin HUANG

    Published 2024-12-01
    “…Using the observation data of 10 m surface wind speed at 173 meteorological stations in Northwest China from 1979 to 2020 and the ERA-5 reanalysis data, this study investigated the interdecadal variation characteristics of annual and seasonal surface wind speed in Northwest China and displayed the background circulation changes of interdecadal variation in 2003/2004.There are significant regional differences in the trend distribution of surface wind speed during 1979 -2020.The stations of the wind speed with increasing trend were mainly located in central and eastern Gansu, Shaanxi, southwest and northeastern parts of Xinjiang.The others stations generally showed the negative trends of wind speed.The number of the stations with decreasing trends of surface wind speed were obvious larger than that with decreasing trends.The average surface wind speed in the stations with decreasing (increasing) trends were larger (smaller) than that in whole northwest China.The distribution of the annual and four-season leading mode of surface wind speed were generally opposite to the trend distribution from 1979 to 2020.All the PC1s experienced the decadal shift around 2000.The second mode showed positive anomalies over the Ningxia Province and southern Shaanxi Province and negative over others regions.The PC2s both witnessed the decadal shifts in 1987/1988 and 2003/2004.Numerical studies investigated the decadal shift of surface wind speed northwest China in 1987/1988.Therefore, this study focuses on analyzing the possible circulation background of the decadal shift of northwest wind speed in 2003/2004.The composite difference of 500 hPa and 200 hPa geopotential heights between 2004 -2020 and 1988 -2003 presents the meridional dipole mode of Central Asia-Northern Europe in spring, the "Silk Road Pattern" in summer and autumn, the "Scandinavian" mode in winter, and the negative phase of the Arctic Oscillation in annual field.The circulation changes in four seasons and annual averages have their own characteristics.It needs further studies of the physical process of the influences of these circulation factors on the decadal shift of the surface wind speed in northwest China in 2003/2004.…”
