Abstract: A method for screening pesticide residues in medicine food homology (MFH) characteristic agricultural products includes step 1, a liquid chromatography-mass spectrometry database of pesticides is constructed, standard solution are prepared for the pesticides and liquid chromatography and mass spectrometry are used to detect the standard solutions; step 2, a sample is processed and then is detected to obtain a liquid chromatography-mass spectrogram; step 3, the liquid chromatography-mass spectrogram obtained from step 2 and liquid chromatography-mass spectrograms in the liquid chromatography-mass spectrometry database obtained from step 1 are compared and analyzed individually.

Abstract: A material with pine-branch like samarium oxide/graphene/sulfur gel structure, and a preparation method and use thereof. The material is reduced graphene oxide carrying pine-branch like samarium oxide on the surface to form a cross-linked gel structure, and sulfur is loaded on the gel structure. The preparation method includes: subjecting graphene oxide and a samarium salt to hydrothermal reduction to prepare a reduced graphene oxide/samarium precursor; under an inert atmosphere, thermolysing the reduced graphene oxide/samarium precursor to obtain a reduced graphene oxide/pine-branch like samarium oxide gel; and melting and diffusing the sulfur onto the reduced graphene oxide/pine-branch like samarium oxide gel. The material with pine-branch like samarium oxide/graphene/sulfur gel structure greatly improves the electrochemical performance of lithium-sulfur batteries.

Abstract: The present disclosure relates to the field of silica gel, and discloses a liquid optical silica gel composition, optical silica gel, a double-glazed photovoltaic assembly and a fabrication method of the optical silica gel. The present disclosure discloses a liquid optical silica gel composition. The composition contains vinyl silicone oil, hydrogen-containing silicone oil, hydrogen-containing MQ silicone resin, a catalyst, an inhibitor and a tackifier. The weight ratio between the vinyl silicone oil, the hydrogen-containing silicone oil, the hydrogen-containing MQ silicone resin and the tackifier is 1:(0.001-0.1):(0.0001-0.08):(0.001-0.05). The hydrogen-containing silicone oil contains first hydrogen-containing silicone oil and second hydrogen-containing silicone oil. The first hydrogen-containing silicone oil has a hydrogen content of 0.1 to 1 percent by weight. The second hydrogen-containing silicone oil has a hydrogen content of 0.01 to 0.1 percent by weight.
