Tensile experiments were carried out on advanced high strength steel (AHSS) by the test machine Gleeble3500, under the temperature ranging from 650 to 850 and the strain rate of 0.1/s~5/s, and the corresponding stress-strain curves were obtained. The peak stress level decreases with the increasing of deformation tempe…
Y1-xGdxBa2Cu3O7-yfilm with BaZrO3was fabricated on CeO2buffered LaMnO3/ion beam assisted deposition MgO/Gd2Zr2O7/Hastelloy C276TMsubstrates by the trifluoroacetates metal organic deposition process, whose microstructural and elemental analyses were performed by transmission electron microscopy. Y1-xGdxBa2Cu3O7-yfilm w…
Cu-12 wt.%Al (Cu-12Al) alloy fabricated by continuous unidirectional solidification (CUS) process has high elasticity, high strength, high conductivity, high plasticity and other good comprehensive properties, which has a potential to develop into a high-performance elastic material as the alternative to beryllium bro…
The research and development of the holographic data storage (HDS) is advanced, as one of the high-speed, mass storage systems of the next generation. Recently, along the development of the write-once system that uses photopolymer media, large capacity ROM type HDS which can replace conventional optical discs becomes…
For the formation of gradient structures with a high concentration of alloying elements in the surface layer of hard cermet alloys, combined ion-beam irradiation with different energies and compositions was used. It was established that preliminary high-power ion-beam treatment and subsequent high-dose implantation by…
The three-dimensional models of the Working-roll of Carder are founded by three-dimensional design software Solidworks and the working process of Working-rolls is simulated by finite element analysis software Cosmos, which obtain overall stress distribution for the Working-roll of Carder. The relations between the wor…
In this study, the authors have presented results for fabricated ZnO based FET and the UV-photoconductive characteristics of Na doped ZnMgO thin films. The electrical measurements confirmed that the conductivity of the Na doped ZnMgO thin film is p-type, and the carrier mobility was estimated to be 2.3 cm2V-1S-1. Moreov…
We have investigated the effects of Al incorporation into a Pr-oxide/Si gate stack formed by atomic layer deposition. The PrAlO x (PAO) layers show an amorphous structure by the incorporation of Al into the Pr-oxide. The PAO sample with 10%-Al shows good C-V characteristics without a hump, and the interface state dens…
The axial interaction of chloroindiumtetraphenylporphyrin with pyridine is studied in a mixed binary benzene-pyridine solvent of variable composition. Thermodynamic parameters of the process are determined. It is concluded on the basis of the results that the binding of pyridine to chloroindiumtetraphenylporphyrin is…
It is well known that the martensitic transformation of YSZ from the metastable tetragonal phase (T-phase) to the monoclinic phase (M-Phase) is accelerated in hot water (especially at 473K). Trace quantities of alumina are known to aid densification, and is also exceptionally resistant to low-temperature degradation (…
TRL-NS is a potent MR contrast agent with comparable properties to TRL. Dynamic in-vivo MR measurements after application of TRL-NS showed a two phase SNR change with a rapid exponential SNR decrease in order of vena cava, aorta, portal vein followed by a protracted SNR recovery in all vessels. Liver and BAT showed an…
Nanocrystalline LaFeO3 with particle size of about 50 nm was directly synthesized by sol–gel auto-combustion method at room temperature. The overall process involves three steps: formation of homogeneous sol; formation of dried gel; and combustion of the dried gel. Single phase nanocrystalline LaFeO3 powders were succ…
After dissolve PVDF in DMF, porous PVDF beads were prepared by water assistant. The porous beads were better crystallized and possessed greater relative surface than ordinary PVDF. The results suggested that the relative surface of PVDF reach 6.53m2/g while the dripping speed was 0.95ml/min. The material could rise to…
Activated carbon supported gold nanoparticles (Au/C) were prepared by a chemical reduction process using NaBH4as a reducing agent. The characterization of transmission electron microscope indicated that the Au nanoparticles (AuNPs) in the Au/C catalyst were highly well dispersed on the carbon support. The catalytic ac…
Mass production of carbon nanofibers (CNFs) on a water soluble support has been achieved by chemical vapor deposition method. Carbon nanofibers have been synthesized using metal (Ni, Co, Fe) acetate as catalyst precursors at 680°C. Upon pyrolysis this catalyst yields metal nanoparticles directly. The sodium chloride w…
Polysilsesquioxane xerogels have been prepared via hydrolysis and condensation of the sole precursor N-(3-Trimethoxysilylethyl)ethylenediamine (TMSEEDA) with no acid or base catalyzed sol–gel processing. Complex siloxane matrix is formed along with abundant and covalently linked ethylenediamine (EDA). After high tempe…

Abstract The work presents the research results of the silumin coat structure applied on the carbidic alloy ductile iron with the metal matrix: pearlitic, bainitic and martensitic. The coats were made in the AlSi5 silumin bath at the temperature tk = 750±5°C. The holding time of cast iron element in the bath was τ = 1…
The electromagnetic noise suppression characteristics of a series of FeCoBM -Al2O3 amorphous soft magnetic films were reported in the frequency range from 0.5GHz to 6 GHz. Effect of dopants on the reflection coefficient (S11), transmission coefficient (S21) and power loss (PLOSS/PIN) of as-deposited FeCoBM(M=Nb, Zr, H…
TN International and International Nuclear Services started commonly in early 2000s the Fuel Integrity Project (FIP) to develop a methodology to assess the response of fresh and used light water reactor (LWR) fuel assemblies (F/A) during 9 m regulatory drops. The analysis of experimental knowledge acquired from fresh…
