It is found that the doping of cerium ion into anatase TiO2 can improve the electrorheological (ER) effects of TiO2 and broaden the operational temperature rang
A new method is presented to determine the thickness of spiral galaxies. Based on the rigorous solution of the Poisson equation for logarithmic density disturba
A functional field effect transistor with self-organized In0.15Ga0.85As/GaAs quantum wires (QWRs) as a channel was achieved by molecular beam epitaxy on a (553)
We use a three-dimensional pulsar magnetosphere model to study the light curve and spectra of x-rays and gamma-rays from the Crab pulsar. In this model, the ver
