| 1 | High areal capacitance of Fe3O4-decorated carbon nanotubes for supercapacitor electrodes显示文摘A conceptually new approach has been developed for the fabrication of magnetite(Fe3O4)-decorated carbon nanotubes(M-CNTs)for negative electrodes of electrochemical supercapacitors.M-CNTs were prepared by an ultrasonic-assisted chemical synthesis method,which involved dispersion of functionalized CNTs in water,Fe3O4 formation on the CNTs surface,and particle extraction through liquid-liquid interface(PELLI).Palmitic acid was found to be an efficient new extractor for PELLI.The slurries produced after drying and redispersing M-CNTs and slurries obtained using PELLI were used for electrode fabrication.The electrodes prepared using PELLI showed superior performance due to reduced particle agglomeration.Testing results provided an insight into the influence of Fe3O4/CNTs mass ratio on the capacitance and capacitance retention at high charge-discharge rates.A capacitance of 5.82 F cm−2(145.4 F g−1)was achieved in Na2SO4 electrolyte using electrodes with high active mass of 40 mg cm−2 and ratio of active mass to current collector mass of 0.6.Good electrochemical performance was achieved at low impedance.The capacitance of the negative M-CNTs electrodes was comparable with capacitance of advanced positive MnO2-CNTs electrodes,which was beneficial for the fabrication of asymmetric devices.The asymmetric device has been fabricated,which showed promising performance in a voltage window of 1.6 V. | Mohamed Nawwar Ryan Poon Ri Chen Rakesh PSahu Ishwar KPuri Igor Zhitomirsky | 2019 | Carbon Energy2019，1，1： | 5 |
| 2 | Hypoglycemic and antioxidant activities of Caesalpinia ferrea Martius leaf extract in streptozotocininduced diabetic rats显示文摘Objective: To evaluate the antidiabetic and antioxidant ef ects of aqueous ethanolic extract of Caesalpinia ferrea(C. ferrea) leaf in normal and streptozotocin(STZ) induced diabetic rats.Methods: Male Sprague-Dawley rats divided into 6 groups of 6 rats each were assigned into diabetic and non-diabetic groups. Diabetes was induced in rats by single intraperitoneal administration of STZ(65 mg/kg body weight). C. ferrea extract at the doses of 250 and 500 mg/kg body weight was orally administered to both diabetic and non-diabetic animals for a period of 30 days. After completion of experimental duration serum, liver and pancreas were used for evaluating biochemical and histopathological changes.Results: Oral administration of C. ferrea leaf extract significantly reduced elevated serum glucose, α-amylase, liver function levels and signii cantly increased serum insulin, total protein and body weight as well as improved lipid proi le due to diabetes. Furthermore, the treatment resulted in a marked increase in glutathione peroxidase, superoxide dismutase, catalase and reduced glutathione, and diminished levels of lipid peroxidation in liver and pancreas of diabetic rats. Histopathological studies demonstrated the reduction in the pancreas and liver damage and coni rmed the biochemical i ndings.Conclusions: From the present study, it can be concluded that the C. ferrea leaf extract ef ectively improved hyperglycaemia while inhibiting the progression of oxidative stress in STZ-induced diabetic rats. Hence, it can be used in the management of diabetes mellitus. | Sherien Kamal Hassan Nermin Mohammed El-Sammad Amria Mamdouh Mousa Maha Hashim Mohammed Abd el Razik Hussein Farrag Amani Nassir Eldin Hashim Victoria Werner Ulrike Lindequist Mahmoud Abd El-Moein Nawwar | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，6： | 3 |
