Synthesis of Composite Materials Based Eggshell Reinforced with Silver Nanoparticles for Possible Biomedical Applications L.A.
The design and manufacture of cermet-type composite materials aims to obtain materials with physical, mechanical, and chemical properties that are better than those of their component materials.
Calcium-based ceramic composite materials, such as carbonates and phosphates, have made them the most prominent materials of this type since, for example, bones are mainly constituted of calcium.
It should be noted that the material formed after the sintering process is different from the materials of the green samples.

The Reliability of Micro-spring Under Dynamic Circumstances Lou Wenzhong1, a, Liu Peng1, b, Li Kang2, c, Ding Xuran1, a 1State Key Laboratory of Mechatronics Engineering and Control, Beijing Institute of Technology, Beijing, China, 100081 2School of Electronic and Optical Engineering, Nanjing University of Science and Technology, Nanjing, China, 210094 alouwz@bit.edu.cn (corresponding author), bLeopardliupeng@126.com, coscarlikang@gmail.com, Keywords: Micro-spring; reliability; Griffith theory of brittle fracture; dynamical circumstances Abstract: This article mainly focuses on the reliability of micro-spring, which as a typical component of MEMS device, applies electrodeposited nickel material and is fabricated by LIGA process, being used under the circumstances like transporting and restoring which may induce shock and crash.
Griffith theory of brittle fracture In 1921 Griffith studied strength of the glass when crack appeared and grew, then he put forward the energy release rate theory that materials break in low-stress situation is caused by the instability of micro-crack extension [4].
Micro-spring mechanical characteristic experiment under dynamical circumstances MEMS material mechanical properties are important parameters in determining the performance of these micro-components; some research institutes launched a large number of tests in MEMS design process.
Material properties of the electrodeposited nickel fabricated by LIGA process are shown in Table 1.
