| 1 | Preparation and Catalytic Application of Novel Water Tolerant Solid Acid Catalysts of Zirconium Sulfate/HZSM-5显示文摘Esterification of acrylic acid(AA) to produce AA esters has widespread application in the chemical industry. A series of water tolerant solid acid catalysts was prepared, and characterized by XRD, nitrogen adsorption, TGA-DTA, XPS, and ammonia adsorption FTIR. The effects of Si/Al ratio, zirconium sulfate(ZS) loading on HZSM-5 and calcination temperature on the esterification were investigated. When 20%(mass fraction) ZS is loaded on HZSM-5, the conversion of AA reaches 100%. XRD analysis indicates that ZS is highly dispersed on HZSM-5 because no crystalline structure assigned to ZS is found. Catalytic activity and hydrophobicity of ZS supported on HZSM-5 are higher compared with those of parent ZS or HZSM-5. Results show that this kind of novel catalysts is an efficient water tolerant solid acid catalyst for esterification reactions. | JIANG Ya-jie JUAN Joon Ching MENG Xiu-juan CAO Wei-liang YARMO Mohd Ambar ZHANG Jing-chang | 2007 | Chemical Research in Chinese Universities2007，23，3： | 11 |
| 2 | A comprehensive review on energy storage in hybrid electric vehicle显示文摘The sharp inclination in the emissions from conventional vehicles contribute to a significant increase in environmental issues,besides the energy crises and low conversion efficiency leads to the evolution of electric vehicles(EV).Hybrid electric vehicles(HEV) have efficient fuel economy and reduce the overall running cost,but the ultimate goal is to shift completely to the pure electric vehicle.Despite this,the main obstruction of HEV is energy storage capability.An EV requires high specific power(W/kg) and high specific energy(W$h/kg) to increase the distance travelled and reduce the time required for charging.The main focus of this paper is on the energy sources as these are the main components in EVs towards making them eco-friendly and cost-effective.Various topologies of EV technology such as HEVs,plug-in HEVs,and many more have been discussed.These topologies of EVs are based on the diverse combination of batteries,fuel cells,super-capacitor,flywheels,regenerative braking systems,which are used as energy sources and energy storage devices. | Shrey Verma Shubham Mishra Ambar Gaur Subhankar Chowdhury Subhashree Mohapatra Gaurav Dwivedi Puneet Verma | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021，8，5： | 6 |
| 3 | Ex vivo antioxidant effects of D-004, a lipid extract from Roystonea regia fruits, on rat prostate tissue显示文摘瞄准:调查是否有 D-004 的口头的处理,古巴的皇室成员的一篇类脂化合物摘录把水果藏在掌内,在正常和睾丸激素(T) 的前列腺织物生产抗氧化剂效果对待的老鼠。方法:在我们的第一个实验,正常老鼠被散布进五个组:与车辆对待的一个组和与 D-004 (100, 200, 400 或 800 mg/kg ) 对待的四个组。在我们的第二个实验,老鼠被使随机化进五个组:一个否定控制组和四个注射 T 的组。后者由与与 D-004 (200, 400 或 800 mg/kg ) 对待的车辆,和三个组对待的一个积极控制组组成。结果:在正常老鼠, D-004 (100-800 mg/kg ) 显著地并且 dose-dependently 禁止了开始铁的 malondialdehyde (MDA ) 在前列腺 homogenates (35.7%-80.0%) 对控制的累积。分别地, D-004 (200-800 mg/kg ) 显著地在正常老鼠的前列腺 homogenates 把基线 MDA 和羰基组归结为约 80% 和 50%(100%) 在对待 T 的老鼠。结论:有 D-004 的口头的处理在正常、注射 T 的老鼠 dose-dependently 并且显著地减少了 MDA 和羰基组。这些调查结果证明在有效的剂量给阻止前列腺增生的 D-004 也在前列腺织物生产抗氧化剂效果。 | Yohani Perez Vivian Molina Rosa Mas Roberto Menendez Rosa M.

| 16 | Protective effects of D-002 on experimentally induced gastroesophageal reflux in rats显示文摘AIM:To investigate the effects of beeswax alcohols(D-002)on the esophageal damage induced by gastroesophageal reflux(GER)in rats.METHODS:Sixty male rats were randomized into six groups(10 rats/group):a negative control and five groups with experimentally induced GER:a positive vehicle control,three treated with D-002(25,100 and 200mg/kg,respectively),and one with omeprazole 10 mg/kg.All treatments were given by gastric gavage.One hour after dosing,GER was produced by simultaneous ligation of the pyloric end and the forestomach.Esophageal lesions index(ELI),gastric secretion volume and acidity,and esophageal malondialdehyde(MDA)and sulfhydryl(SH)group concentrations were measured.Statistical significance was considered at P<0.05.RESULTS:As compared to the negative control,the positive control group exhibited increased ELI(5.2±0.33 vs 0±0,P=0.0003),gastric secretion volume(2.69±0.09 vs 0.1±0.0,P=0.0003)and acidity(238±19.37 vs 120.0±5.77,P=0.001),and esophageal concentrations of MDA(2.56±0.1 vs 1.76±0.28,P=0.001)and SH groups(1.02±0.05 vs 0.56±0.08,P=0.0003).D-002(25,100 and 200 mg/kg)reduced ELI(3.36±0.31,2.90±0.46 and 2.8±0.23,respectively)vs the positive control(5.2±0.33)(P=0.004;P=0.002;P=0.001,respectively).There were no significant changes in acidity with D-002 treatment,and only the highest dose reduced the volume of the gastric secretion(1.92±0.25)vs the positive control(2.69±0.09,P=0.013).D-002(25,100 and 200 mg/kg)lowered the esophageal MDA(2.05±0.16,1.98±0.22and 1.93±0.22,respectively)(P=0.01;P=0.03;P=0.03,respectively)and SH group concentration(0.87±0.06,0.79±0.08 and 0.77±0.06,respectively)(P=0.04;P=0.04;P=0.02)vs the positive control(2.56±0.10 and 1.02±0.05,respectively).Omeprazole decreased ELI(2.54±0.47),gastric secretion volume(1.97±0.14)and acidity(158.5±22.79),esophageal MDA(1.87±0.13)and SH group(0.72±0.05)concentrations vs the positive control(P=0.002;P=0.001;P=0.02;P=0.003;P=0.002,respectively).CONCLUSION:Acute oral administration of D-002 decreased macroscopic esophageal lesions and oxidative stress in rats with experimentally induced GER,without modifying gastric secretion acidity. | Zullyt Zamora Vivian Molina Rosa Mas Yazmin Ravelo Yohany Perez Ambar Oyarzabal | 2014 | World Journal of Gastroenterology2014，20，8： | 1 |
