The similarities and differences in the surface and microstructure are characterizedby infrared spectroscopy, Raman spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy, andtransmission electron microscopy. Compared with high-purity graphene, the introduction of functional groups leads to moredefects in the two-dimensional structure. The quality of graphene, reflected by the intensity ratio of peak D and G modesin the Raman spectroscopy, is consistent with that observed by scanning electron microscopy and transmission electronmicroscopy. The infrared spectra of graphene-based two-dimensional carbon materials are different from that of high-puritygraphene, and the absorption peaks of the functional groups are obvious. The X-ray photoelectron spectroscopy resultsillustrate the diverse chemical states of carbon, and the atomic ratio of carbon to oxygen directly reflects the quality ofthe graphene-based materials. The results of electron microscopy and spectroscopic characterization of graphene samplesprovide an excellent basis for a wide range of applications in graphene production and quality control.展开更多

[ Method ] M. peniciosa ofA. b/sporus was taken as the detection bacteria, and nine kinds of chemicals were conducted plate efficacy test in the laboratory. Mushroom house validation was carried out for the screened chemicals with strong inhibition to M. peniciosa. [ Result] Nine kinds of chemicals had obvious difference in control effects on M. peniciosa and effects on growth ofA. bisporus; 2 400 and 3 200 times dilution of 78% Boer MZ WP and 2 400 times dilution of 69% Fulishuang WP after casing material processing had good control effects on M. peniciosa and had no apparent adverse effects on mycelial growth and fruiting development of A. bisporus. [ Conclusion] The 2 400 and 3 200 times dilution of 78% Boer MZ WP and 2 400 times dilution of 69% Fulishuang WP are worth popularizing.展开更多
