On the other hand, 70% of the world's metal materials need deforming to be made into product, so how to achieve low-carbon of metal forming equipment is significant.
It can be seen that structural optimization of mass distribution of hydraulic press's moving beam can not only reduce the use of materials in design phase, but also can greatly cut down energy consumption during use.
Topology Optimization of Hydraulic press’s Moving Beam 3.1 The Basic Theory of Topology Optimization The effective use of materials has been the target of human, the aims of Structural optimization is to seek a safe and economic structural patterns structure topology optimization is also known as generalized shape and contour optimization, and it can be dated back to the truss theory put forward by micelle in 1904 [9].
For production units of hydraulic press, the successful design of new moving beam can make the weight of beams decrease from the original 43542kg to 35781kg, which can directly save materials 7761kg.

Furthermore, the micro/nano capsule for drugs is promising in drug targeting and controlled release owing to the versatility of shell materials and easily crossing blood brain barrier (BBB).
Therefore, the investigation of micro/nano capsule for drugs is a hot issue both in the filed of material science and medical science.
Up to date, the shell material of micro/nano capsule has been widely investigated.
