A DFT Study on C-H Bond Activation of Methane by CeO2 and CeO2-doped with Metal Cations
甲烷是天然气的主要成分,是燃料和化学品中非常出色的原材料,但甲烷又是非常稳定的分子,其活化常需较高的温度,因此,研究有效活化甲烷,特别是较低温下转化甲烷的催化剂,具有理论和实际的研究意义。近年来,研究表明二氧化铈基纳米催化剂具有良好的低温活化甲烷性能,但其活性中心本质和活化机理尚不很清楚。为此,我们采用密度泛函理论(DFT)方法,对二氧化铈及掺杂不同金属阳离子的二氧化铈体系活化甲烷C-H进行了计算研究。其主要研究内容和结果如下: 1.以(CeO2)m(m=1-3)团簇为模型对甲烷C-H在其上活化及活化机理进行了探索。研究发现,甲烷C-H在团簇上的活化为亲核加成模式,电子由团簇流向甲烷C-H反...Methane is the main constituent of natural gas and an important type of feedstock for making of fuel and chemical. However methane is very stable and its activation often needs high temperature. Therefore, it is significant in theory and practice to investigate the efficient catalysts for methane activation, especially at low temperature. Recently, it had reported that CeO2-based nano-catalysts ex...学位:理学硕士院系专业:化学化工学院_物理化学学号:2052012115152
Mechanisms of Cadmium Tolerance and Detoxification in Sesuvium portulacastrum L.
近年来由于电镀业、化工业、采矿业蓬勃发展导致大量镉进入水体、大气、土壤环境中,造成严重的镉污染问题,严重威胁生物生命安全。目前镉污染问题已经成为当今世界共同关注的环境问题之一,植物修复法作为一种“绿色”的污染治理手段,由于具有低成本、高净化效率等优点,成为国际上的热点研究领域。目前,植物修复方法的应用越来越广泛,但仍存在很大的局限性,大部分超累积植物生物量少,修复效果不理想,且只能适用于低盐土壤或淡水水域修复,而能够用于盐碱地、湿地及海水水域等盐度较高区域重金属修复的相关植物较少。 海马齿作为盐生植物在高盐环境下依旧能够正常生长,有望成为修复受重金属污染且盐度较高区域的优势植物。虽然近年已有...In recent years due to the electroplating industry, chemical industry, mining industry to flourish, lead to a lot of cadmium into the water, air and soil environments, causing serious pollution of cadmium, what will pose a serious security threat to biological life.

The mechanism study of the membrane lipid raft gene flotillins in the process of pathogen infection in Scylla paramamosain
拟穴青蟹(Scyllaparamamosain)是我国东南沿海分布的重要海水养殖蟹类之一,具有高的营养价值和经济价值。集约化的养殖模式导致近年来拟穴青蟹疾病频发,而细菌性病原,特别是以弧菌等革兰氏阴性菌为主的病原是青蟹发病的重要诱因,对其致病入胞途径和机制的研究能够为控制拟穴青蟹疾病爆发提供科学依据。前期的研究表明青蟹感染溶藻弧菌3h后,SpFLT-1mRNA在血淋巴细胞和鳃中显著上调表达,且该蛋白分布于青蟹血淋巴细胞和鳃上皮细胞的膜脂筏结构中,与弧菌蛋白之间发生共定位,暗示它们之间可能存在相互作用。本研究在前期工作基础上,改进了RNAi技术的有效性,并构建了SpFLT-1蛋白在细胞中的过表达...The mud crab, Scylla paramamosain is one of the most important marine breeding crabs in China, with vital nutritional and economic value.

目的评估早孕妇女亚临床甲状腺功能减退症(subclinical hypothyroidism,SCH)对妊娠结局的影响及药物治疗的必要性。方法收集18 243例在厦门大学附属第一医院产前检查直至分娩的病例,诊断标准为妊娠10~12周产前检查时TT4与FT4正常而TSH≥2.5 m IU/L为SCH,甲状腺过氧化物酶抗体(thyroid peroxidase antibody,TPOAb)≥34 U/L为阳性。根据TSH的升高程度不同、TPOAb情况、能否遵医嘱按时按量服用L-T4使TSH控制在正常范围内进行分组:2.5 m IU/L≤TSH≤5.0 m IU/L且TPOAb阳性且能遵医嘱者为A组,不能遵医嘱者为B组;TSH>5 m IU/L且TPOAb阳性且能遵医嘱者为C组,不能遵医嘱者为D组;2.5 m IU/L≤TSH≤5.0 m IU/L且TPOAb阴性且能遵医嘱者为F组,不能遵医嘱者为G组;TSH>5 m IU/L且TPOAb阴性且能遵医嘱者为H组,不能遵医嘱者为K组。并随机抽取200例同期甲状腺功能正常的病例作为对照组(E组),回顾分析早孕妇女甲状腺功能异常的发生率、SCH对妊娠结局的影响、早孕妇女SCH行左旋甲状腺素片(L-T4)替代治疗的剂量及影响因素。结果早孕妇女SCH检出率为5.20%,甲状腺功能正常率为79.00%。A组早产3.31%(8/242)、妊娠期高血压7.02%(17/242)、胎儿生长受限7.02%(17/242)、出生低体质量儿6.61%(16/242)的发生率均低于B组的8.79%(8/91)、14.29%(13/91)、15.38(14/91)、14.29(13/91)(P均 5 m IU / L,TPOAb was positive and had good compliance; Group D: TSH and TPOAb as Group C but not have good compliance; Group F: 2. 5 m IU / L≤TSH≤5. 0 m IU / L,TPOAb was negative and had good compliance; Group G: as Group F,but not have good compliance; Group H: TSH > 5 m IU / L,TPOAb was negative and had good compliance; Group K: as Group H,but not have good compliance. Randomly selected 200 cases with normal thyroid function at the same period as the control group( Group E). Retrospective analysis the occurrence rate of thyroid gland dysfunction,the influence of SCH to pregnancy outcome,the doses and influencing factors of replacement therapy by L-T4 to SCH of early pregnant women. Results Relevance ratio of SCH in early pregnant women was5. 20%,the ratio of normal thyroid function was 79. 00%. In group A,premature birth 3. 31%( 8 /242),gestational hypertension 7. 02%( 17 /242),fetal growth restriction 7. 02%( 17 /242),low birth weight infant 6. 61%( 16 /242),were lower than that in group B 8. 79%( 8 /91),14. 29%( 13 /91),15. 38( 14 /91),14. 29( 13 /91) respectively( P < 0. 05). In group C,spontaneous abortion 3. 31%( 6 /181),premature birth 3. 89%( 7 /181),gestational hypertension 8. 29%( 15 /181),gestational diabetes mellitus 3. 89%( 7 /181),fetal growth restriction 7. 73%( 14 /181),low birth weight infant 6. 63%( 12 /181),were lower than that in group D 11. 54%( 6 /52),11. 54%( 6 /52),19. 23%( 10 /52),11. 54%( 6 /52),17. 31( 9 /52),15. 38( 8 /52)( P < 0. 05). No significant statistical difference were found in multiple comparison of the above six indexes of group A,B,C. And just the same as the multiple comparison of group F,G,H,K,E. When TSH reach the standard,the dosage of L-T4 in group A and C had significant difference [( 0. 757 ± 0. 378 vs. 1. 106 ± 0. 454) μg / kg,t = 8. 39,P < 0. 001]. There were also significant differences of group F compared with group H[( 0. 443 ± 0. 198 vs. 0. 813 ± 0. 378) μg/kg,t = 8. 22,P < 0. 001],group( A + F) compared with group( C + H) [( 0. 634 ± 0. 358 and 1. 017 ±0. 427) μg / kg,t = 11. 77,P < 0. 001],group A compared with group F [( 0. 757 ± 0. 378 vs. 0. 443 ± 0. 198) μg / kg,t = 9. 85,P < 0. 001 ],group C compared with group H [( 1. 106 ± 0. 45 vs. 0. 813 ± 0. 378) μg / kg,t = 5. 59,P < 0. 001],group( A + C) compared with group( F + H) [( 0. 932 ±0. 463 vs. 0. 693 ± 0. 388) μg / kg,t = 6. 53,P < 0. 001]. Conclusion The early pregnant women with SCH and TPOAb positive could increase the occurrence rate of spontaneous abortion,premature birth,gestational hypertension,gestational diabetes mellitus,fetal growth restriction and low birth weight infant. The early intervening treatment of L-T4 could efficiently decrease the adverse event occurrence ratio of pregnant woman with SCH and positive TPOAb,but no effect for that with SCH and TPOAb negative. The TSH level and condition of TPOAb could affect the replacement therapy dosage of early pregnancy with SCH
