A series of novel polynuclear iron-based photosensitizers (1–3) with cyano-bridged to form a molecular square were synthesized and their optical, electrochemical, and photovoltaic properties were investigated. The modification of anchoring groups with 4,4'-dicarboxy-2,2'-bipyridine, 2,2'-bipyridine, and 4,4'-dimethoxy-2,2'-bipyridine does not show significant changes on the both absorption and electrochemical...
Discontinuous Galerkin (DG) finite element method is well-suited on unstructured meshes for high order approximation with the freedom of choosing the order of basis functions in each element locally. Moreover, DG can handle complicated geometries with curved boundary easily. Further, since information exchange in DG only involves neighboring elements, high efficiency in parallelization can be achieved...
Multiscale or multi-physics modeling play a major role in many important problems today. In the past few years, there have been increasingly growing research activities aiming at developing novel multiscale computational methods. In this work, we focus on one challenge multiscale heterogeneous problem, modeling electromagnetic wave scattering from a composite unmanned aerial vehicle (UAV). Two new...
A trigger device of pulsed power facility is introduced in this paper. The trigger device is composed of Marx generate, power supply, trigger, and et al. The principle of Marx generate (in the paper) is outlined. Equivalent circuit of charging is analyzed, and the waves of charging voltage and current are respectively simulated. Then equivalent circuit of discharging is analyzed, and the wave of output...
