BiFeO3 has been attracted among multiferroic materials because it has a potential candidate for room temperature commercial applications such as smart devices, random access memories, spintronics, magnetic field sensors, and dielectric resonator oscillator (DRO) materials [2].
The primary characteristic of DRO materials such as high relative permittivity (εr), high Q factor (low dielectric loss, tanδ), and low-temperature coefficient of resonant frequency (τf) [10].Therefore BiFeO3 as multiferroic material could be a subject for oscillator material.

The WST configuration for quasi-brittle materials was first published in 1986 [7].
Another test configuration suitable for determination of fracture parameters of quasi-brittle materials is modCT.
This material is in ATENA Science used for connections between different materials with the possibility to set the parameters of contact (friction coefficient, cohesion, stiffness of normal, tangential stiffness, tensile strength, etc.) [5].

It is found that the DMFC performance of the membranes modified by two kinds of catalytic materials are better than that of the bare Nafion when operated with 2.0 M methanol.
In this research, two kinds of catalytic materials, platinum and palladium are used to modify Nafion.
In order to increase the compatibility between the Pt(Pd) and polymer, some organic materials are needed to bind well with both Nafion and Pt(Pd).

The results allow us to choose the geometrical parameters ​​for milling cutter, apart from the working parameters for processing the surface of wood materials with the highest quality as possible.
The processed materials are tropical woods, churasia and canarium, with dimensions as follows: length of wood samples lw = 1000mm, width b = 20 ... 22mm.
Conclusions In the paper having theoretical and experimental researches on the chip formation and surface shaping of churasia and canarium wood materials while milling, the cutting tool material is carbide WCCO6.

Two-component or multi-component composite materials today occupy a large place in modern construction.
This article analyzes the methodology for testing the thermophysical properties of these materials, reveals a new approach to determine it, taking into account the links between the thermal conductivity and the thermal diffusivity of materials.
Parker to measure the thermal diffusivity of a variety of different materials in 1961.
The obtained results have been compared with the known tabular data of the test materials [11, 19].

Some scholars especially in developed countries have paid attention on how to upgrade the properties of cement and concrete materials to the grade of aluminium, steel and fibre materials.
Experimental Materials.
Therefore, the greatest packing density of the cement-based materials increases from 0.72 to 0.80 and the strength of the cement-based materials rises.
