Abstract: For practical applications such as artifical joints and dental implants, there is a strong
demand for hydroxyapatite coatings with excellent performances to ensure long-term fixation.
Materials and Methods Nano-crystalline HA powders were prepared in our laboratory by adding Ca(NO3)2 solution into NH4H2PO4 solution.
No microcracks or separation between the different materials was observed, and a few un-melted particles and pores distributed in the coating.

Keywords: Hexavalent chromium; Nanoscale zero-valent iron (NZVI); Humic acid (HA); Landfill leachates; Critic acid
Abstract.
Due to the small particle size, large surface area, and high reactivity, nanoscale zero-valent iron (NZVI) has been demonstrated for potential use in environmental engineering [5, 6].
Various materials have been found to be effective, including thiols, surfactant, and polymers [8, 13].
However, not all of these materials are applicable to the interest of nanoparticles.
Materials and Methods Materials The following reagents were used in this study: HA, K2CrO4, NaOH, NH3·H2O, citric acid, deionized (DI) water (analytical grade, First Chemical Reagent Manufactory), and NZVI particles (99%, mean diameter: 80 nm, commercial grade).

Experiment Details
In this current paper, P92 steel pipe was selected as experimental material with outside diameter (D) of 575mm, wall thickness (t) of 35mm, and length (L) equal to 1250mm.
The calculation results are suitable for other types of 9%Cr heat-resistant steel because of similar material properties.
In conclusion, the key of local PWHT is assuring soak band width of inner wall rather than thermal stress related to axial temperature gradient meets desired requirement for 9% Cr heat-resistant steel pipes.

II.Materials and Methods A.
Materials and chemicals Bovine fibrinogen, agarose were purchased from Sigma Chemical Co.
The effect of nitrogen source on production of fibrinolytic activity, as shown in Table 1, indicated that soybean cake powder, soybean powder and hydrolysate of soybean by limited hydrolysis were proper materials for production of the enzyme by Coprinus comatus YY-20.
That soybean protein was used as materials for production of fibrinolytic enzymes by microorganism was also reported by several research groups [1,4,5,6,7,8,11,20].

Introduction
Equipment battlefield repair has the characteristics of urgent time, heavy task, harsh environment and constrained resources, so the key to win the high tech war is to recover effectively combat performance in the shortest time.
It is a great conflict. 3) The quick equipment’s renewal speed, insufficient security personnel ability, scarce repair materials and battle damage assessment, all bring difficulties and obstacles for equipment’s repair.
The fifth level of standard solution can also be considered to have strong constraints on introducing and interaction of new material.
Improving design, and looking for standard materials; If anyone has solved a similar problem?

Process, material, tooling and machines are the four major challenges that should be resolved in this technology.
With the friction principle implemented in the grippers, there is no limitation on the workpiece material, gripping force and the environment conditions.
The actuation principle is chosen based on the force required for the engagement of the fingers, it can be created by a hydraulic (in the macro scale) or electrostatic (in the nano scale with fingers made by piezoelectric materials) means.
