Therefore carbon materials are hybrided to prepare SnO2 composites to improve the cell performance.
The four samples began to decompose at 400˚C, and this may be due to the combustion of carbon materials in oxygen air.

Using Tecnomatix Plant Simulation software, we could optimize material flow, resource utilization and logistics for all levels of plant planning.
We used the standard transfer strategy is cyclic, non-blocking, meaning that the current object moves the MU to the first non-blocked succeeding object in the flow of materials.
