Empirical potential We used a many-body empirical potential, the Tersoff potential function, which has been widely used to develop the empirical potential function for several element and compound materials.
The Tersoff potential is based on the bond-order concept with good +Corresponding author : kok@semilab3.ee.cau.ac.kr Title of Publication (to be inserted by the publisher) transferability and has been an effective tool for evaluating new materials.
The referred papers summarized the comparison between the experimental and the calculated results of cubic materials.
The calculated equilibrium lattice constants of cubic materials are identical to the experimental results and the values of bulk modulus are in agreement with the experimental results.
Considering that the cohesive energies for the cubic BN, AlN and GaN structures are –6.630, –5.815 and –4.450 eV/atom, respectively, the cohesive energies for the NTs for the studied III-N materials are below 96.8, 85.6 and 98.8 % of the bulk materials.

In fact, it leads to stimulate research focuses on producing medical product especially from polymer raw materials.

Introduction Negative Poisson's ratio materials expand transversely when stretched axially, and also undergo transverse contraction under axial compression.
There is increasing interest in the development of these novel materials, known as auxetic materials [1], due to their counter-intuitive behaviour and also in applications where the auxetic property itself, or enhancements in other materials properties due to a negative Poisson's ratio, may be exploited.
The development of auxetic nanomaterials is expected to lead to high modulus auxetic materials as well as having potential in sensor, molecular sieve and separation technologies [2].

Influence of Brick Powder with Different Replacement Ratio on Concrete Performance and its Microscopic Mechanism Te Li1,a*, Laire Tier2,b 1Faculty of Materials Science and Engineering, Chongqing University, Chongqing 400000, China 2Faculty of Materials Science and Engineering, Southeast University, Nanjing 210000, China a*lairetier@seu.edu.cn, bTeLi@cqu.edu.cn Keywords: Brick powder; Concrete; Workability; Mechanical properties; Durability Abstract.
This paper studies the influence of brick powder on the performance of cement-based materials.
Fig.1 Chemical Composition of materials Compared with cement, the CaO content of brick powder was less, SiO2 and Al2O3 were the main chemical components of brick powder, The SEM images of raw materials are shown in Fig. 2.
The pores in gelling materials can be classified as gel pores ( <10 nm), medium pores (10 nm-100 nm), capillary pores (100 nm-1000 nm) and large pores (> 1000 nm) , which are reported to be harmless or less harmful to the gelling materials below 100 nm.

Most of the past research on grinding mechanisms for hard and brittle materials has followed either the “indentation fracture mechanics” approach or the “machining” approach [6].
It provides important insights into the nature of the grinding process for the material.
Micro/nano indentation is a valuable method used to test the mechanical characteristics of materials including glasses, which including hardness, Young’s modulus and fracture toughness, etc.
Cracks initiated by the Vickers indentation under a load of 40 N on many kinds of brittle crystalline and amorphous materials were observed [7].

Factory overhead consists of the costs of operating the factory other than direct labor and materials.
Groover [5] observes that materials spend more time waiting or handling than in process.
Combination of the Fig.2 and Fig.3 show that other than materials and parts, direct labor and machinery are main parts of manufacturing cost.
It is determined based on the flows of materials between departments and the distances between the locations of the departments.
