| 2 | Yiguanjian cataplasm attenuates opioid dependence in a mouse model of naloxone-induced opioid withdrawal syndrome显示文摘OBJECTIVE:To investigate the effect of Yiguanjian(YGJ) cataplasm on the development of opioid dependence in a mouse model of naloxone-induced opioid withdrawal syndrome.METHODS:One hundred Swiss albino mice,of equal male to female ratio,were randomly and equally divided into 10 groups.A portion(3 cm2) of the backside hair of the mice was removed 1 day prior to the experiment.Morphine(5 mg/kg) was intraperitoneally administered twice daily for 5days.YGJ cataplasm was prepared and pasted on the bare region of the mice immediately beforemorphine administration on day 3 and subsequently removed at the end day 5.On day 6,naloxone(8mg/kg) was intraperitoneally injected to precipitate opioid withdrawal syndrome.Behavioral observation was performed in two 30-min phases immediately after naloxone injection.RESULTS:The YGJ cataplasm significantly and dose-dependently attenuated morphine-naloxone-induced experimental opioid withdrawal,in terms of withdrawal severity score and the frequencies of jumping,rearing,forepaw licking,and circling behaviors.However,YGJ cataplasm treatment did not alter the acute analgesic effect of morphine.CONCLUSION:YGJ cataplasm could attenuate opioid dependence and its associated withdrawal symptoms.Therefore,YGJ cataplasm could serve as a potential therapy for opioid addiction in the future. | Gao Shuai Gao Hong Fan Yuchen Zhang Guanghua Sun Fengkai Zhao Jing Li Feng Yang Yang Wang Kai | 2016 | Journal of Traditional Chinese Medicine2016，36，4： | 1 |
| 3 | Enhanced activation of persulfate using mesoporous silica spheres augmented Cu–Al bimetallic oxide particles for bisphenol A degradation显示文摘Herein,Cu–Al bimetallic oxide was synthesized and mixed with mesoporous silica spheres via a simple hydrothermal method.The prepared sample was then analyzed and employed to activate potassium peroxydisulfate for bisphenol A removal.Based on the results of X-ray diffraction,scanning electron microscopy,and energy dispersion spectroscopy,Cu–Al bimetallic oxide was determined as CuO-Al2O3,and mesoporous silica spheres were found around the these particles.At 30 min,a bisphenol A degradation level of 90%was achieved,and it remained at over 60%after five consecutive cycles,indicating the catalyst’s superior capacity and stability.In terms of removal performance,the radical pathway(including■OH•,and■)and singlet oxygen(■)bisphenol A,potassium peroxydisulfate,and the catalyst played a dominant role.The introduction of Al2O3 promoted the formation of surface oxygen vacancies,which improved ligand complex formation between potassium peroxydisulfate and the catalyst,thereby facilitating electron migration.Furthermore,mesoporous silica spheres augment not only enhanced bisphenol A adsorption but also alleviated Cu leaching.Overall,this work is expected to provide significant support for the rational development of catalysts with high catalytic activity for persulfate activation via surface electron migration. | Fulong Wang Liang Sun Ziyu Zhang Fengkai Yang Jinlong Yang Weijian Liu | 2023 | Frontiers of Chemical Science and Engineering2023，17，10： | 0 |
| 4 | A reevaluation of the correlation between the synthesis parameters and structure and properties of nitrogen-doped carbon nanotubes显示文摘Nitrogen-doped carbon nanotubes(NCNTs) were synthesized by chemical vapor deposition using cobaltbased oxides as catalyst and ethylenediamine(EDA) as carbon/nitrogen precursor. The influence of growth time,EDA concentration and growth temperature on the morphology,yield,composition,graphitization and oxidation resistance of the NCNTs was systematically investigated by using Raman spectroscopy,temperature-programmed oxidation and other techniques. The NCNT growth from ethylenediamine with a high N/C ratio involves several processes including mainly(1) catalytic growth of NCNTs,(2) homogeneous gas-phase decomposition of EDA,(3) non-catalytic deposition of pyrolytic carbon/nitrogen species and(4)surface etching of amorphous carbon or carbon at defect sites through gasification. At a later growth stage the etching process appears to be dominating,leading to the thinning of nanotubes and the decrease of yield.Moreover,the surface etching through carbon gasification strongly influences the structure and degree of graphitization of NCNTs. | Kunpeng Xie Fengkai Yang Petra Ebbinghaus Andreas Erbe Martin Muhler Wei Xia | 2015 | Journal of Energy Chemistry2015，24，4： | 0 |
| 5 | Promoting effect of nitrogen doping on carbon nanotube-supported RuO2 applied in the electrocatalytic oxygen evolution reaction显示文摘RuO_2 nanoparticles supported on multi-walled carbon nanotubes(CNTs) functionalized with oxygen(OCNTs) and nitrogen(NCNTs) were employed for the oxygen evolution reaction(OER) in 0.1 M KOH.The catalysts were synthesized by metal-organic chemical vapor deposition using ruthenium carbonyl(Ru_3(CO)_(12)) as Ru precursor. The obtained RuO_2/OCNT and RuO_2/NCNT composites were characterized using TEM, H_2-TPR, XRD and XPS in order probe structure–activity correlations, particularly, the effect of the different surface functional groups on the electrochemical OER performance. The electrocatalytic activity and stability of the catalysts with mean RuO_2 particle sizes of 13–14 nm was evaluated by linear sweep voltammetry, cyclic voltammetry, and chronopotentiometry, showing that the generation of nitrogen-containing functional groups on CNTs was beneficial for both OER activity and stability. In the presence of RuO_2, carbon corrosion was found to be significantly less severe. | Kunpeng Xie Wei Xia Justus Masa Fengkai Yang Philipp Weide Wolfgang Schuhmann Martin Muhler | 2016 | Journal of Energy Chemistry2016，25，2： | 0 |
