| 1 | A comparison of transmittance properties between ZnO∶Al films for transparent conductors for solar cells deposited by sputtering of AZO and cosputtering of AZO/ZnO显示文摘Aluminum-doped zinc oxide (AZO) thin films were deposited on sapphire (002) and glass substrates by two different sputtering techniques radio frequency magnetron cosputtering of AZO and ZnO targets and sputtering of an AZO target. The dependence of the photoluminescence (PL) and transmittance properties of the AZO films deposited by cosputtering and sputtering on the AZO/ZnO target power ratio, R and the O2/Ar flow ratio, r were investigated, respectively. Only a deep level emission peak appears in the PL spectra of cosputtered AZO films whereas both UV emission and deep level emission peaks are observed in the PL spectra of sputtered AZO films. The absorption edges in the transmittance spectra of the AZO films shift to the lower wavelength region as R and r increase. Effects of crystallinity, surface roughness, PL on the transmittance of the AZO films were also explained using the X-ray diffraction (XRD), atomic force microscopy (AFM), and PL analysis results. | LEE Chongmu YIM Keunbin CHO Youngjoon Lee J.G. | 2006 | Rare Metals2006，25，z1： | 8 |
| 2 | Evaluation of an erosion-sediment transport model for a hillslope using laboratory flume data显示文摘Climate change can escalate rainfall intensity and cause further increase in sediment transport in arid lands which in turn can adversely affect water quality. Hence, there is a strong need to predict the fate of sediments in order to provide measures for sound erosion control and water quality management. The presence of microtopography on hillslopes influences processes of runoff generation and erosion, which should be taken into account to achieve more accurate modelling results. This study presents a physically based mathematical model for erosion and sediment transport coupled to one-dimensional overland flow equations that simulate rainfall-runoff generation on the rill and interrill areas of a bare hillslope. Modelling effort at such a fine resolution considering the flow connection between interrill areas and rills is rarely verified. The developed model was applied on a set of data gathered from an experimental setup where a 650 cm×136 cm erosion flume was pre-formed with a longitudinal rill and interrill having a plane geometry and was equipped with a rainfall simulator that reproduces natural rainfall characteristics. The flume can be given both longitudinal and lateral slope directions. For calibration and validation, the model was applied on the experimental results obtained from the setup of the flume having 5% lateral and 10% longitudinal slope directions under rainfall intensities of 105 and 45 mm/h, respectively. Calibration showed that the model was able to produce good results based on the R2(0.84) and NSE(0.80) values. The model performance was further tested through validation which also produced good statistics(R2=0.83, NSE=0.72). Results in terms of the sedigraphs, cumulative mass curves and performance statistics suggest that the model can be a useful and an important step towards verifying and improving mathematical models of erosion and sediment transport. | Anya Catherine CARGUELLES MinJae JUNG Kristine Joy BMALLARI GiJung PAK Hafzullah AKSOY Levent M KAVVAS Ebru ERIS JaeYoung YOON YoungJoon LEE SeonHwa HONG | 2014 | Journal of Arid Land2014，6，6： | 3 |
| 3 | Serial blood concentration of polyethoxylated tallow amine and clinical presentations in acute herbicide poisoning显示文摘Most commercially available herbicides contain surfactants as co-formulants to increase adhesion and absorption by plant leaves.Ethoxylated amines,one of the most used surfactants,are non-ionic and derived from animal fats.They represent a class of surfactants with similar structural features,including polyethoxylated tallow amine(POEA).POEA is widely used in glyphosate,glufosinate-containing herbicides.In 2015,the European Food Safety Society(EFSA)concluded that POEA was more toxic than glyphosate when tested in glyphosate-based formulations.[1]They also attributed the poisoning following ingestion by humans to the presence of POEA. | Jungsoo Park Sun Cheun Kim Youngjoon Jeon Yong Chul Cho Changshin Kang Yeonho You Hong Joon Ahn Seung Ryu Jihan Lee Wonjoon Jeong | 2022 | World Journal of Emergency Medicine2022，13，4： | 2 |
