| 1 | Phytoremediation of petroleum polluted soil显示文摘An experimental study of the rhizosphere effect on phytoremediation of petroleum polluted soil was carried out with three species of grasses,namely Pannicum,Eleusine indica(L.)Gaerth,and Tall Fescue.After a period of 150 days,this pot experiment showed that the rhizosphere of these three species accelerated the degradation of petroleum hydrocarbons to different extents.The results showed that the number of microorganisms in the rhizosphere increased by three orders of magnitude.The induction of the plant rhizosphere and the coercion influence of petroleum changed the species and activity of microorganisms.The degradation of petroleum hydrocarbons in the rhizosphere was 3-4 times that in unplanted soil.The dehydrogenase activity in the rhizosphere was 1.61-2.20 times that in unplanted soil, but the catalase activity was 0.90-0.93 times that in unplanted soil,and soil moisture content increased by 5%compared with the unplanted soil. | Wang Jing Zhang Zhongzhi Su Youming He Wei He Feng Song Hongguang | 2008 | Petroleum Science2008，5，2： | 12 |
| 2 | Review of the atmospheric corrosion of magnesium alloys显示文摘Mg atmospheric corrosion is induced by a thin surface aqueous layer. Controlling factors are microgalvanic acceleration between different phases, protection by a continuous second phase distribution, protection by corrosion products, and degradation of protective layers by aggressive species such as chloride ions. The Mg atmospheric corrosion rate increases with relative humidity (RH) and concentrations of aggressive species. Temperature increases the corrosion rate unless a protective film causes a decrease.O2, SO2 and NO2 accelerate the atmospheric corrosion rate, whereas the corrosion rate is decreased by CO2. The traditional gravimetric method can evaluate effectively the corrosion behavior of Mg alloys. | Hongguang Liu Fuyong Cao Guang-Ling Song Dajiang Zheng Zhiming Shi Mathew S.Dargusch Andrej Atrens | 2019 | Journal of Materials Science & Technology2019，35，9： | 7 |

| 5 | Exogenous application of succinic acid enhances tolerance of Larix olgensis seedling to lead stress显示文摘Larix olgensis A. Henry(Changbai larch) is a productive commercial species and good candidate for afforestation in northeast China. It is widely planted in lead-stressed soils which can induce oxidative damage in this plant. Increasing tolerance to lead(Pb) stress is therefore of keen interest. A greenhouse experiment was conducted to identify the biomass, physiological responses and Pb accumulation of L. olgensis seedlings to Pb stress under succinic acid(SA) application and to explore the interaction of exogenous SA applications and stress resistance. L. olgensis seedlings were planted in Pb-stressed or unstressed haplic cambisols in pots. In Pb-contaminated soils the seedlings were treated daily with concentrations of SA solutions at a rate approximately equivalent to 0, 0.04,0.2, 1.0, or 2.0 mmol kg^(-1) of soil for 10, 20, and 30 days,respectively. Pb treatment induced damage in the seedlings and led to the inhibition of biomass accumulation in roots,stems and leaves, and a rise in Pb accumulation in fine roots and leaves. Malondialdehyde(MDA) content and electrolyte leakage in leaves significantly increased while peroxidase(POD) activities, soluble protein and photosynthetic pigment contents in leaves were all reduced.Physiological toxicity was promoted with increasing Pb treatment times. When Pb-stressed seedlings were exposed to SA(especially 10.0 mmol L-1 over 20 days), the physiological responses for Pb-only were reversed and the biomass of roots, stems, and leaves dramatically increased.SA facilitated Pb uptake in fine roots and leaves but more Pb accumulated in fine roots. The results demonstrate that exogenous SA alleviates Pb-induced oxidative injuries and improves the tolerance of L. olgensis seedlings to Pb stress. | Jinfeng Song Hongguang Zhang Chengwei Duan Xiaoyang Cui | 2018 | Journal of Forestry Research2018，29，6： | 2 |

| 7 | Phase behavior and properties of salt-free cationic/anionic surfactant mixtures of oleic acid and stearic acid显示文摘Cationic base surfactant, tetradecyltrimethylammonium hydroxide (TTAOH), can be obtained through anion exchange from tetradecyltrimethylammonium bromide (TTABr). Salt-free cationic and anionic (catanionic) surfactant mixtures were studied by mixing TTAOH with oleic acid (OA) or stearic acid (SA) in water. The phase behavior of TTAOH/OA/H2O is compared with that of TTAOH/SA/H2O. It was found that the phase behavior of TTAOH/OA/H2O and TTAOH/SA/H2O system differs from each other due to the existence of the unsaturated double carbon bond (C=C) in OA. At fixed total surfactant concentration (25 mg/mL) of TTAOH/OA/H2O system at 25℃, one can observe an isotropic L1 phase, and a L1/Lα two-phase region with increasing OA content. The volume of top turbid Lα phase increases while the bottom phase changes gradually from transparently clear to a bit turbid until a single Lα-phase is reached. Finally at high OA concentration, excess OA is separated from the bulk aqueous solutions. TTAOH/SA/H2O system usually forms white precipitating at 25℃ due to the high chain melting temperature of SA. When heated to 60℃, however, the state of samples changes. At fixed total surfactant concentration of 25 mg/mL, an isotropic L1 phase and a milk-white or bluish Lα-phase are observed with increasing SA concentration. Transparent thin layers which are strongly birefringent form at the tops of some samples within the Lα-phase region. Finally, at high SA concentration, excess SA is separated from the bulk aqueous solutions. In addition to phase behavior study, we also measured the conductivity of TTAOH/OA/H2O system at 25℃ and TTAOH/SA/H2O system at 60℃, respectively. Surface tension and rheological measurements were also performed on typical samples. | ZHAO DianYing LI HongGuang SONG AiXin HAO JingCheng | 2009 | Chinese Science Bulletin2009，54，21： | 0 |
| 8 | Bilobalide inhibits the expression of aquaporin 1, 4 and glial fibrillary acidic protein in rat brain tissue after permanent focal cerebral ischemia显示文摘The present results demonstrated that in an adult rat model of permanent middle cerebral artery occlusion (pMCAO), pretreatment with bilobalide reduced brain water content and infarct area, down-regulated aquaporin 1, 4 mRNA expression in brain edema tissue, then inhibited their synthesis in the striatum, in particular at the early stage of ischemia (at 8 hours after pMCAO), inhibited glial fibrillary acidic protein expression, and lightened reactive gliosis. These data sug-gest that bilobalide attenuates brain edema formation due to reduced expression of aquaporins. | Haiming Qin Fulin Song Hongguang Han Hong Ou Xingwen Zhai Bin Qin Song You | 2011 | Neural Regeneration Research2011，6，27： | 0 |
| 9 | Reduction potential of the energy penalty for CO_(2) capture in CCS显示文摘CO_(2) capture and storage(CCS)has been acknowledged as an essential part of a portfolio of technologies that are required to achieve cost-effective long-term CO_(2) mitigation.However,the development progress of CCS technologies is far behind the targets set by roadmaps,and engineering practices do not lead to commercial deployment.One of the crucial reasons for this delay lies in the unaffordable penalty caused by CO_(2) capture,even though the technology has been commonly recognized as achievable.From the aspects of separation and capture technology innovation,the potential and promising direction for solving this problem were analyzed,and correspondingly,the possible path for deployment of CCS in China was discussed.Under the carbon neutral target recently proposed by the Chinese government,the role of CCS and the key milestones for deployment were indicated. | Yawen ZHENG Lin GAO Song HE Hongguang JIN | 2023 | Frontiers in Energy2023，17，3： | 0 |
| 10 | Research on Key Technology of Efficient Production of Bovine Embryos显示文摘[Objectives]This study was conducted to explore the effects of three different splitting fluids on the bisection effects of bovine morulae and blastocysts.[Methods]With the help of a micromanipulator,the morulae and blastocysts that were routinely produced in the body from the 6 th to the 8 th d were divided into half-embryos in vitro to observe their development,and the half-embryos with a restored morphology and a blastocyst trophoblast were selected.[Results]The success rates of bisection of morulae in PBS+0.2 mol/L sucrose and PBS+5%PVP were significantly higher than that in PBS(P<0.05),and the values in the three liquids were 95.7%,97.2% and 50%,respectively,while the blastocyst development rates and of half-embryos and the pregnancy rates of transplantation were not significantly different(P>0.05).When blastocysts were bisected in PBS+0.2 mol/L sucrose and PBS+5% PVP,the success rates of bisection were significantly higher than that of PBS(P<0.05),and the values in the three liquids were 96.8%,95.5% and 50.0%,respectively,while the development rates of half-embryos and the pregnancy rates of transplantation were not significantly different(P>0.05).The development rate of half-embryos bisected from blastocysts was significantly higher than that of morulae.[Conclusions]This study improves the efficiency of bovine embryo bisection,which is beneficial to the application of embryo bisection technology in cattle breeding. | Guizhi TONG Hongguang WANG Yongsheng HAN Xintao LI Weixia WANG Bin SONG | 2020 | Agricultural Biotechnology2020，9，4： | 0 |
| 11 | Study on the critical stress threshold of weakly cemented sandstone damage based on the renormalization group method显示文摘During the microstructural analysis of weakly cemented sandstone,the granule components and ductile structural parts of the sandstone are typically generalized.Considering the contact between granules in the microstructure of weakly cemented sandstone,three basic units can be determined:regular tetrahedra,regular hexahedra,and regular octahedra.Renormalization group models with granule-and pore-centered weakly cemented sandstone were established,and,according to the renormalization group transformation rule,the critical stress threshold of damage was calculated.The results show that the renormalization model using regular octahedra as the basic units has the highest critical stress threshold.The threshold obtained by iterative calculations of the granule-centered model is smaller than that obtained by the pore-centered model.The granule-centered calculation provides the lower limit(18.12%),and the pore-centered model provides the upper limit(36.36%).Within this range,the weakly cemented sandstone is in a phase-like critical state.That is,the state of granule aggregation transforms from continuous to discrete.In the relative stress range of 18.12%-36.36%,the weakly cemented sandstone exhibits an increased proportion of high-frequency signals(by 83.3%)and a decreased proportion of low-frequency signals(by 23.6%).The renormalization calculation results for weakly cemented sandstone explain the high-low frequency conversion of acoustic emission signals during loading.The research reported in this paper has important significance for elucidating the damage mechanism of weakly cemented sandstone. | Zhaoyang Song Hongguang Ji Zhiqiang Liu Lihui Sun | 2020 | International Journal of Coal Science & Technology2020，7，4： | 0 |
