a series of fe3o4 supported on mesoporous fdu-12 silica systems were prepared by the hydrothermal conditions. the surface properties of the functionalized catalyst were analyzed by a series of characterization techniques like ftir, xrd, n2 adsorption–desorption and tem. xrd and adsorption–desorption analysis shows that the mesostructure of fdu silica remains intact after fe3o4 modifications, wh...

Abstract In this work, a magnetically separated photocatalyst with great efficiency CuCe-Ferrite/TiO 2 composite was prepared and characterized by X-ray diffraction (XRD), UV–Vis spectrophotometry, Fourier transformer infra-red spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), high resolution transmission (HR-TEM), energy dispersive (EDX) vibrating sample magnetometer (...

We present a scheme for laser cooling applicable to an extremely dilute sample of magnetically trapped antihydrogen atoms (H̄). Exploiting and controlling the dynamical coupling between the H̄’s motional degrees of freedom in a magnetic trap, three-dimensional cooling can be achieved from Doppler cooling in one dimension using the 1s1/2 − 2p3/2 transition. The lack of three-dimensional access to ...
