Carbon nanocoils (CNCs) were synthesized by a thermal chemical vapor deposition (CVD) method over tin-coated type 202 stainless steel (SS) plates (Cr 15%, Mn 10%, Ni 1%). It is considered that the calcination at 900 °C leads to the crazing of the SS surface, which causes the Fe (Ni) and Sn to be fully mixed and forms active Fe (Ni)-Sn-O catalyst particles suitable for the growth of CNCs. However,...
The dike engineering is an important part in the system of flood controlling. landslides is the main reason that leads to the dike break.In order to study the dike stability in an irrigation area, the dike slope stability is analyzed based on the strength reduction method and finite element method, and the safety factors of dike slope under the four typical calculation cases are calculated in this...
