Many of these nanotechnology applications need to engineer surface on which the nano-materials can build on.
Improvement of the accuracy of nano-feature shape needs controllable erosion methods which can remove excessive materials as required.

FATIGUE AND FRACTURE CHARACTER OF METAL RUBBER MATERIAL Yuming LI1,a, Hongbai BAI1,b JianchunYANG2,c 1University of Ordnance Engineering, China 2University of Science and Technology Beijing, China aliyuming1976@sina.com, bbhbk11@sina.com, cyjc675266@163.com Keywords: Metal rubber, Damaging Factor, Fatigue Test, Fracture Face, Electronic Scanning Microscope Abstract.
Introduction With the development of science and technology in space, the spacecrafts usually work in the worse circumstance such as high or low temperature, so they need to improve their components’ performance of vibration and sealing.
A main reason may be that it is a kind of particular materials, the testing measures and theories of metal material can’t be used here.
The fracture and fatigue character of MR is different from the metal material.

RS biochar can be synthesized from RS to serve as supercapacitor electrode materials.
Methodology 2.1 Materials: RS was obtained from a farm in New Borg El-Arab, Alexandria, Egypt.
The resulting biochar was washed with 2 M HCl to remove unreacted materials using a refluxing setup for 1 hour.
