The effect of the heat treatment on both the catalytic activity for the oxygen reduction reaction (ORR) and the properties of ZrOxNy has been examined.
However, their activities were not so high, and the factor which affected the catalytic activity was not clarified.
It has been well known that a heat treatment during ZrOxNy deposition affects the properties of ZrOxNy, such as structural, mechanical and optical properties [12-14].
This suggested that the properties of the film changed at around 500 oC.
Therefore, the crystal structure and the crystallinity would be the main factors to affect the electrocatalytic activity for ORR Acknowledgement The authors wish to thank the Japan Science and Technology Agency (JST) and the New Energy and Industrial and Technology Development Organization (NEDO) for their financial support.

It is difficult or impossible for a bulk monolithic material to possess all the above-mentioned properties while combining with required bulk mechanical properties [3].
Preliminary experiments have revealed that the physical properties of such composites depend to a large degree on the properties of performs [7,8], while the tribological properties are based on squeezing the lubricant phase out, which leads to the formation of a surface film protecting the friction surfaces against seizure and scoring (self-lubrication effect) [9].
The object of this research was to investigate the synthesis and characterization of HSS-based self-lubrication composites which possessed the appropriate morphology and mechanical and tribological properties.
It can be seen that the porosity increased approximately linearly with increasing PFA content and was affected by the variation in χ, as shown in Fig. 2 (a).
The proportion χ constitutes a limiting factor on the ratio of open porosity to total porosity, and the maximum occurs at χ = 2:3.

This paper surveys some properties and characteristics of SiC wafers purchased in the commercial market place and describes the product variability among vendors as a method to highlight the areas where improvements in substrate quality are desirable.
There, discrepancies in counts of a factor of 2 or more have been observed.
The band edge peak intensity appears to be greatly affected by polish quality and subsurface damage.
For stepper lithography, focus and exposure are affected by the resultant surface of the wafer, which determines the definition of fine line-widths over the exposure fields of the wafer.
Over time this has proven to be a more repeatable and easier measurement technique than using mechanical calipers or laser techniques.

Hence, the predictability of any metal cutting model largely depends on the accuracy of the constitutive model for the work material properties.[4] Merchant [5] and others [6–9] assumed that the shear flow stress is equal to that obtained from the conventional tensile tests.
The SHPB method is useful to evaluate the effect of individual factor such as strain, strain rate or temperature on the flow stress.
So the influence of thermal softening and strain hardening on sample properties could be ignored.
Metal cutting tests provide some advantages over the SHPB method and other independent material tests to estimate the material properties in cutting conditions.

Despite the huge number of published studies, there remain big uncertainties about the materials properties.
The problem is strongly nonlinear since each field interacts with others and affects the physical properties of the materials.
In the present study, these factors are taken into account.

Recently, magnetic nanofluids have been the subject of much interest due to their unusual optical, electronic and magnetic properties, which can be changed by applying an external magnetic field [2].
Magnetic nanofluid showing unique properties of fluidity and magnetic tunability is promising to study especially for many applications such as magnetic fluid hyperthermia in cancer treatment, tunable optical switches, sensors and loudspeakers [3].
Particle volume concentration is also one of the parameters that affect the thermal conductivity and heat transfer rate as a result.

Liu guoshou [1], Zhang tianhui [2] etc. have applied four methods of reliability to analyze the da/dN of ADB610 steel’s three zones: base material (BM), heat affected zone (HAZ) and welded metal (WM) at the stress ratio of R=0.1 and concluded the variation law of c and m, which are parameters in the Paris formula, of course, they also have calculated the da/dN of different zones.
The basic mechanics properties parameters are shown in table 1.

The logarithm of N was taken as the random variable xij, namely: 2) The mean () and the standard deviation () of xij was calculated; 3) The da/dN with reliability () was got when brined standard normal deviator () and standard deviation correction factor k, specific process as shown:, where k was decided by the number of sample, for this test, there was seven samples under the stress ratio R=0.1, so k was 1.042 by looking up table[5].
First of all, in order to get da/dN data, we needed to fit curve of (a, N) according to seven increasing points polynomial (only for this paper), then calculated the stress intensity factor delta K, so that we could get a series of (da/dN, delta K) data points, and then analyzed the da/dN under the same stress intensity factor.

Taking into account some factors, such as processing conditions, corrosion resistance, hot ductility, etc. we may reasonably come to the conclusion that 1.13% boron concentration in the steel has a better absorption capacity to the low-energy neutron and can effectively reduce the secondary γ-ray effect, meeting the request of radiation protection with reduced material thickness.
Introduction In recent years, with the extensive development of nuclear power, neutron logging and spallation neutron sources research work, Demand for new neutron shielding materials is becoming increase at home and abroad, and boron steel developed by Kobe Steel Factory of Japan is an excellent neutron shielding material because its strong thermal neutrons absorptive capacity and good mechanical properties which can make bending and welding operation easier[1], its promotion can help to optimize shielding structure, reduce shielding weight and volume, so the boron steel has been widely used in the nuclear power industry and nuclear technology application device[2].
In this paper, we simulates interaction between slow neutrons and steel to determine excellent material properties of boron steel by the Monte Carlo method and the MCNP code, and meet the requirement of new nuclear radiation shielding material, such as light texture, small size, resistance high temperature and other characteristics.
As shown in Fig.1(c), attenuation properties of boron steel to 1 keV neutrons are still have a great influence, when the neutron decay 90%, SUS304 needs 24.8 cm thick and KTA-304 steel plate needs 11.6 cm and 9.38 cm., corresponding to 1.13% and 2% boron concentration.
Conclusions This paper studies the properties of boron steel for slow neutron absorption and attenuation, It indicates that there is a great impact on the slow neutron absorption properties due to change of the boron concentration, actually, shield material can use 1.13% boron steel in nuclear waste disposal and transportation container and other materials to absorb slow neutrons.
