| 1 | Analytical and finite-element study of optimal strain distribution in various beam shapes for energy harvesting applications显示文摘Owing to the increasing demand for harvesting energy from environmental vibration for use in self-powered electronic applications, cantilever-based vibration energy harvesting has attracted considerable interest from various parties and has become one of the most common approaches to converting redundant mechanical energy into electrical energy. As the output voltage produced from a piezoelectric material depends largely on the geometric shape and the size of the beam, there is a need to model and compare the performance of cantilever beams of differing geometries.This paper presents the study of strain distribution in various shapes of cantilever beams, including a convex and concave edge profile elliptical beam that have not yet been discussed in any prior literature. Both analytical and finite-element models are derived and the resultant strain distributions in the beam are computed based on a MATLAB solver and ANSYS finite-element analysis tools. An optimum geometry for a vibration-based energy harvesting system is verified.Finally, experimental results comparing the power density for triangular and rectangular piezoelectric beams are also presented to validate the findings of the study, and the claim, as suggested in the literature, is verified. | B.L.Ooi J.M.Gilbert A.Rashid A.Aziz | 2016 | Acta Mechanica Sinica2016，32，4： | 8 |

| 3 | Three-dimensional oscillation of an acoustic microbubble between two rigid curved plates显示文摘Understanding the near boundary acoustic oscillation of microbubbles is critical for the effective design of ultrasonic biomedical devices and surface cleaning technologies.Accordingly,this study investigates the three-dimensional microbubble oscillation between two curved rigid plates experiencing a planar acoustic field using boundary integral method(BIM).The numerical model is validated via comparison with the nonlinear oscillation of the bubble governed by the modified Rayleigh-Plesset equation and with the axisymmetric model for an acoustic microbubble in infinite fluid domain.Then,the influence of the wave direction and horizontal standoff distance(h)on the bubble dynamics(including jet velocity,jet direction,centroid movement,total energy,and Kelvin impulse)were evaluated.It was concluded that the jet velocity,the maximum radius and the total energy of the bubble are not significantly influenced by the wave direction,while the jet direction and the high-pressure region depend strongly on it.More importantly,it was found that the jet velocity and the high-pressure region around the jet in acoustic bubble are drastically larger than their counterparts in the gas bubble. | Kawa M.A.Manmi Imad A.Aziz Arun Arjunan Rostam K.Saeed Abdolrahman Dadvand | 2021 | Journal of Hydrodynamics2021，33，5： | 1 |

| 12 | Bipolar tri-state resistive switching characteristics in Ti/CeO_x/Pt memory device显示文摘Highly repeatable multilevel bipolar resistive switching in Ti/Ce Ox/Pt nonvolatile memory device has been demonstrated. X-ray diffraction studies of Ce O2 films reveal the formation of weak polycrystalline structure. The observed good memory performance, including stable cycling endurance and long data retention times(> 104s) with an acceptable resistance ratio(~102), enables the device for its applications in future non-volatile resistive random access memories(RRAMs). Based on the unique distribution characteristics of oxygen vacancies in Ce Ox films, the possible mechanism of multilevel resistive switching in Ce Ox RRAM devices has been discussed. The conduction mechanism in low resistance state is found to be Ohmic due to conductive filamentary paths, while that in the high resistance state was identified as Ohmic for low applied voltages and a space-charge-limited conduction dominated by Schottky emission at high applied voltages. | M.Ismail M.W.Abbas A.M.Rana I.Talib E.Ahmed M.Y.Nadeem T.L.Tsai U.Chand N.A.Shah M.Hussain A.Aziz M.T.Bhatti | 2014 | Chinese Physics B2014，23，12： | 0 |
