Based on third-party logistics, we propose a linear programming mathematic model for reverse logistics networks of waste copper recycling. And, a reverse logistics network models is established to deal with returned products, which will decrease costs and allow optimal decisions on distributing methods so as to increase efficiency and profit levels. A case study is also developed to illustrating the value of this model and network. Whats more, according to the model, we put forward to sincere suggestions and better measures of copper scrap recycling.

Metal-organic gel (MOG), as a novel type of metallic organic hybrid material, exhibits diverse properties. However, the applications in fluorescence detection for specific metal ion have rarely been exploited. In...
