In the experimental aspect, a hardening trend is observed in semiconductor and insulator materials as the thickness of the thin films decreases, while a softening trend is noted in metal materials [19].
This paper primarily discusses four materials, with the data provided in Table 1.
Figure 3 illustrates the variation trend of the Young’s modulus of nanofilms for different materials with thickness.

Usually refers to petroleum asphaltenes are not soluble in n-alkane molecules (such as n-pentane, n-heptane, etc.) and benzene soluble material [13].
Isolated by ultracentrifugation to oil and water, get the black viscous material, with a small angle x-ray scattering analysis of its structure, the measured lattice spacing of 5nm, can be considered by the 2-3 Asphaltene asphaltene particles formed films .

Influence of Temperature on the Cracking of Reinforced Concrete Frame Jin-song Lei 1,2,a , Dong-sheng Yang 2 , Shan-chuan Ying 2 , Yin-sheng Zou 1 1 College of Civil Engineering, Hunan University, Changsha, Hunan 410082, China 2 School of Civil Engineering and Architecture, Southwest University of Science and Technology, Mianyang, Sichuan 621010, China a leijinsong@swust.edu.cn Keywords: temperature influence; concrete frame; temperature stress; concrete cracking.
Because the concrete is composed of several types of materials, traditional method is very difficult in analyzing the concrete cracks [2,3].
To exactly simulate the cracking, the size of beam element must be 2 or 3 times of the biggest framework material in the finite element analysis.

Introduction Grinding process is an energy intensive process that, it requires a larger amount of energy per unit volume of material removal compared to other metal cutting processes [1].
The dressed parameters are: vs=8.64 m/s, vroll=18.84 m/s, ap=1µm, a total thickness of 0.15 mm has been dressed. 40Cr steel (HRC 50) was selected as the workpiece material which has a diameter of 170mm and a width of 18mm.

Anikee is an interactive art installation, and it’s not particular created as curriculum material.
In particular, these tools have transformed how teachers use materials in the classroom with children and communicate with parents and families (Gutnick et al. 2010; Barron et al. 2011).
(Lo, 2004) The illustrations in a picture book not only suggests as an assistant material to the content but plays a more important role to encourage different interpretation to the story.
