This study presents the fabrication of a novel porous composite of graphene oxide‐montmorillonite (GO‐MMT) through the modification of montmorillonite using the freeze‐drying method for the purpose of Pb removal. The characterization of the GO‐MMT composite was conducted using scanning electron microscopy, Fourier transform infrared spectrometry, and X‐ray diffraction. The results from batch adsorption...
The paper introduces the computer education of university at current situation, and analyzes some important teaching problems of low efficiency in the multi-media teaching, the inconformity of teaching and practices in the operational curriculum, inharmonious relations between educational theory and practice in teaching contents, coordination modes of undergraduate employment and graduation design,...
Transmission characteristics of Frequency Selective Surface (FSS) of complex dense elements are analyzed in this paper. The complex elements composed of Y loop and Y geometries are closely packed in triangle form. Based on the spectral-domain method, this FSS structure was analyzed by selecting a new analytical element. It is shown that this complex dense FSS structure has dual-frequency and wide...
