| 2 | Effect of different sol-gel synthesis processes on microstructural and morphological characteristics of hydroxyapatite-bioactive glass composite nanopowders显示文摘The aim of this work was to study the influence of the different synthesis processes on microstructural and morphological characteristics and distribution of hydroxyapatite-bioactive glass(HAp-BG)composite nanopowders obtained by sol-gel method.HAp-BG composite nanopowders with 20 wt%bioactive glass were prepared using a sol-gel method via four routes:(I)mixing the prepared HAp solution with BG solution before aging time;(II)mixing the prepared BG solution with the prepared HAp gel after gelation;(III)mixing the calcined BG nanopowders with the prepared HAp solution;and(IV)mixing the two prepared calcined nanopowders by mechanochemical activation.The prepared nanopowders were evaluated and studied by X-ray diffraction(XRD),scanning electron microscopy(SEM),energy dispersive X-ray spectrometer(EDS),Fourier transform infrared(FTIR),transmission electron diffraction(TEM)and Brunauer-Emmet-Teller(BET)method to investigate the phase structure,microstructure and morphology,functional groups,and the size and distribution of nanopowders.Results indicated that morphology,crystallinity,crystallite size and specific surface area(SSA)of the powders are highly correspondent to the process and type of synthesis method.These findings suggest that the modified sol-gel derived HAp-BG composite nanopowders are expected to efficiently provide a possibility to produce a good candidate to use for fabrication of a bulk nanostructured HAp-BG composite for bone tissue engineering. | Mohamadhassan TAHERIAN Ramin ROJAEE Mohammadhossein FATHI Morteza TAMIZIFAR | 2014 | Journal of Advanced Ceramics2014，3，3： | 1 |
| 3 | Interfacial engineering of lithium-polymer batteries with in situ UV cross-linking显示文摘Developing promising solid-state Li batteries with capabilities of high current densities have been a major challenge partly due to large interfacial resistance across the electrode/electrolyte interfaces.This work represents an integrated network of self-standing polymer electrolyte and active electrode materials with in situ UV cross-linking.This method provides a uniform morphology of composite polymer electrolyte with low thickness of 20-40μm.This modification leads to promising cycling results with 85%specific capacity retention in LijjLiFePO4 cell over 100 cycles at high current densities of 170 mA g1(~25μA cm^(-2),1 C).By applying this method,the interfacial resistance decreases as high as seven folds compared to noncross-linked interfaces.The following work introduce a facile and cost-effective method in developing fastcharging self-standing polymer batteries with enhanced electrochemical properties. | Ramin Rojaee Samuel Plunkett Md Golam Rasul Meng Cheng Vahid Jabbari Reza Shahbazian-Yassar | 2021 | InfoMat2021，3，9： | 0 |
