Eight novel compounds have been synthesized and they are two series of mixed tri(butyl/ cyclohexyl) tin carboxylates:Bu_nCy_(3-n) SnO_2CR (n=1,2;R=n-C_3H_7,C_6H_5,4-ClC_6H_4,4-NO_2C_6H_4).In addition to the studies of...Eight novel compounds have been synthesized and they are two series of mixed tri(butyl/ cyclohexyl) tin carboxylates:Bu_nCy_(3-n) SnO_2CR (n=1,2;R=n-C_3H_7,C_6H_5,4-ClC_6H_4,4-NO_2C_6H_4).In addition to the studies of their structures with IR,^(119)Sn and ^(13)C NMR,we tested their fungicidal,insec- ticidal and acaricidal activities.The percentage of inhibition to the aforementioned phytopathogen is about 80—100% at 50 ppm in glasshouse and 100% for T.Uriticae at 500 ppm.Those findings indicate that this kindof compounds have both fungicidal and acaricidal activities and mayhave a good prospect for applications.展开更多

Introduction The Lithium-sulfur battery(LSB) shows promise as a highdensity energy source, with a theoretical energy density of approximately 2600 W h kg^(-1)[1]. However, practical application of the LSB has been hindered by the “shuttle effect” and Li anode corrosion [2,3]. Highly concentrated electrolytes(HCEs) have been proposed as a solution, as they can inhibit the dissolution of lithium polysulfide and promote homogeneous lithium deposition [4].展开更多
