| 1 | Glutamic acid-assisted hydrothermal recrystallization to configure bamboo-like carbon nanotubes for improved triiodide reduction显示文摘Carbon nanotubes(CNTs)have been far and wide employed as the counter electrodes(CEs)in dyesensitized solar cells because of their individual physical and chemical properties.However,the techniques available now,such as chemical vapor deposition,arc discharge and laser ablation for synthesizing CNTs,commonly suffer from rigorous operations and complicated steps,which make the process difficult to be controlled.Herein,we present a simple and facile glutamic acid-assisted hydrothermal recrystallization strategy to construct bamboo-like CNTs(GHP-BC-x).Generally,the conventional organic dye3,4,9,10-perylene tetracarboxylic dianhydride(PTCDA)is used as a precursor and glutamic acid efficiently promotes the recrystallization of the perylene cores'planarπ-conjugated system in PTCDA under hydrothermal conditions and then self-assembles into one-dimensio nal nano rods with improved crystallization degree,finally resulting in the morphology of bamboo-like CNTs after carbonization.When applied as the counter electrodes,the GHP-BC-3 displays a remarkable power conversion efficiency of8.25%,benefiting from the superb electrical conductivity and mass transfer dynamics,superior to that of Pt CE(7.62%). | Chun Yao Jiangwei Chang Yiwang Ding Chang Yu Jieshan Qiu | 2021 | Chinese Journal of Chemical Engineering2021，34，9： | 0 |
| 2 | Exact Vibration Solutions of Nonhomogeneous Circular,Annular and Sector Membranes显示文摘In this paper,exact vibration frequencies of circular,annular and sector membranes with a radial power law density are presented for the first time.It is found that in general,the sequence of modes may not correspond to increasing azimuthal mode number n.The normalized frequency increases with the absolute value of the power index|n|.For a circular membrane,the fundamental frequency occurs at n=0 where n is the number of nodal diameters.For an annular membrane,the frequency increases with respect to the inner radius b.When b is close to one,the width 1−b is the dominant factor and the differences in frequencies are small.For a sector membrane,n−1 is the number of internal radial nodes and the fundamental frequency occurs at n=1.Increased opening angle b increases the frequency. | Chang YiWang Wang Chien Ming | 2012 | Advances in Applied Mathematics and Mechanics2012，4，2： | 0 |
