| 1 | Distribution and geological significance of 17α(H)-diahopanes from different hydrocarbon source rocks of Yanchang Formation in Ordos Basin显示文摘Based on GC-MS testing data of many saturated hydrocarbon samples, 17α(H)-C30 diahopanes (C30*) are extensively distributed in the lacustrine hydrocarbon source rocks of the Yanchang Formation in Ordos Basin, but show remarkable differences in relative abundance among various source rocks. Generally, Chang 7 high-quality source rock (oil shale) developed in deep lake anoxic environment shows lower C30* content, whereas Chang 6-9 dark mudstone developed in shallow to semi-deep lake, sub-oxidizing environment shows relatively high to high C30* value. Particularly, Chang 7 and Chang 9 black mudstones in Zhidan region in the northeast of the lake basin show extremely high C30* value. A comparative analysis was made based on lithology, organic types and various geochemical parameters indicative of redox environment, and the results indicate that environmental factors such as redox settings and lithology are key factors that control the C30* relative abundance, while organic types and maturity may be minor factors. High to extremely high C30* values are indicative of sub-oxidizing environment of fresh-brackish water and shallow to semi-deep lake. Therefore, research on C30* relative content and distribution in lacustrine hydrocarbon source rocks in the Yanchang Formation, especially on the difference in C30* between Chang 7 high-quality source rocks (oil shale) and Chang 6-91 source rocks (dark mudstone), will provide an important approach for classification of Mesozoic lacustrine crudes and detailed oil-source correlation in the basin. | ZHANG WenZheng YANG Hua HOU LiHui LIU Fei | 2009 | Science China Earth Sciences2009，52，7： | 16 |
| 2 | Polyaspartic acid as a corrosion inhibitor for WE43 magnesium alloy显示文摘The inhibition behavior of polyaspartic acid(PASP)as an environment-friendly corrosion inhibitor for WE43 magnesium alloy was investigated in 3.5 wt.%NaCl solution by means for EIS measurement,potentiodynamic polarization curve,and scanning electron microscopy.The results show that PASP can inhibit the corrosion of WE43 magnesium alloy.The maximum inhibition efficiency is achieved when PASP concentration is 400 ppm in this study. | Lihui Yang Yantao Li Bei Qian Baorong Hou | 2015 | Journal of Magnesium and Alloys2015，3，1： | 8 |
| 3 | Corrosion behavior of Mg-8Li-3Zn-Al alloy in neutral 3.5%NaCl solution显示文摘The corrosion behavior of Mg-8Li-3Zn-Al alloy was investigated in neutral 3.5%NaCl aqueous solution by morphology observation and electrochemical tests.The weight loss method was to measure the corrosion rate.The electrochemical results indicated that the corrosion resistance of Mg-8Li-3Zn-Al alloy in 3.5%NaCl solution is poorer than that in distilled water.The Cl-anion leads to the initiation and development of the corrosion pits.And the corrosion products are mainly Mg(OH)_(2). | Lihui Yang Quantong Jiang Meng Zheng Baorong Hou Yantao Li | 2016 | Journal of Magnesium and Alloys2016，4，1： | 4 |
| 4 | Inhibition of sulfate-reducing bacteria influenced corrosion on hydrophobic poly(dimethylsiloxane)coatings显示文摘Sulfate-reducing bacteria(SRB)has been pointed out as one of the causative agents of microbial induced corrosion in the marine environment.To address this problem,novel strategies are being experimented as against the earlier methods which have been banned due to their toxic effects on useful aquatic lives.Thus,the aim of this study was to investigate the effect of non-toxic perfluorodecyltrichlorosilane(PFDTS)on resistance of hydrophobic poly(dimethylsiloxane)/phosphoric acid-treated zinc oxide(PDMS/PA-treated ZnO)coatings to SRB-induced biofouling and corrosion.The surface features of the coatings before and after exposure to SRB/NaCl solution were analyzed by scanning electron microscopy(SEM).Wettability of the coatings before and after exposure was also measured.The interaction of SRB with the coatings was investigated by FTIR spectroscopy.The resistance performance of the modified coatings against SRB-induced corrosion was monitored by electrochemical impedance spectroscopy(EIS).The EIS measurements revealed that 0.20 g PFDTS-based coating displayed highest corrosion resistance with impedance modulus of 6.301×10^10 after 15 d of exposure to SRB/NaCl medium.The results were corroborated by surface and chemical interaction analyses,and thus,indicate that 0.20 g PFDTSmodified PDMS/PA-treated ZnO coating has potentials for excellent SRB-induced corrosion resistance and anti-biofouling performance. | Innocent O.Arukalam C.N.Njoku Lihui Yang Baorong Hou Ying Li | 2020 | Journal of Materials Science & Technology2020，52，17： | 2 |

| 7 | Study on a noninvasive method for rapid screening Human Serum albumin injectables by Raman spectroscopy显示文摘Human serum albumin(HSA)injectable product is a severely afflicted area on drug safety due to its high price and restricted supply.Raman spectroscopy performances high specificity on HSA detection and it is even possible to determine HSA injectable products noninvasively.In this study,we developed a noninvasive rapid screening method for of HSA injectable products by using portable Raman spectrometer.Qualitative models were established by using principal component analysis combined with classical least squares(PCA-CLS)algorithm,while quanti-tative model was established by using partial least squares(PLS)algorithm.Model transfer in different instruments of both the same and different apparatus modules was further discussed in this paper.A total of 34 HSA injectable samples collected from markets were used for verification.The identification results showed 100%accuracy and the predicted concentrations of those identified as true HSA were consistent with their labeled concentrations.The quantitative results also indicated that model transfer was excellent in the same apparatus modules of Raman spectrometer at all concentration levels,and still good enough in the different apparatus modules although the relative standard deviation(RSD)value showed a little increasing trend at low HSA concentration level.In conclusion,the method was proved to be feasible and efficient for screening HSA injections,especially on its screening speed and the consideration of glass containers.Moreover,with inspiring results on the model transfer,the method could be used as a universal screening mean to different Raman instruments. | Yu Zhao Nan Ji Xiuji Li Jifeng Hou Min Li Yongjian Yang Ping Tian Xinmei Sun Xinyue Xiao Lihui Yin | 2017 | Journal of Innovative Optical Health Sciences2017，，1： | 0 |
