In this study, the microstructure, mechanical properties, corrosion behaviors, and in vitro biocompatibility of Zr-Mo alloys as a function of Mo content after solution treatment were systemically investigated to assess their potential use in biomedical application. The experimental results indicated that Zr-1Mo alloy mainly consisted of an acicular structure of α' phase, while ω phase formed in...

The purpose of this paper is to explain the thermodynamical and shape memory behaviour in comparison with structural parameters for Zr-based intermetallics a new class of potential shape memory alloys (SMA) for high-temperature applications [I]. Electrical resistivity, structural, shape memory and calorimetric measurements were carried out for the Zr2CuNi Zr,CuCo quasibinary cross-section. It w...

Recent results of CRIEPI’s pyro-process fuel cycle technology developments are reported. On the actinides deposition into liquid cadmium cathode, a series of experiments are conducted using a small scale electro-refiner of about a hundred grams actinides inventory. The suitable condition for codeposition of U and TRUs is investigated, by varying Pu/U ratio in the salt from ∞ to 1.7. The design ...

The title mononuclear complex, [Zr(C(20)H(20)Cl(4)N(2)O(2))(2)], was obtained by allowing hexane to diffuse into a diethyl ether solution of zirconium(IV) sec-butoxide and the enanti-o-meri-cally pure tetra-dentate ligand N,N'-bis-(3,5-dichloro-2-hy-droxy-benz-yl)-trans-(R,R)-1,2-diamino-cyclo-hexane. The metal centre is eight-coordinate and displays a distorted dodeca-hedral coordination envir...

The complete sequence of steps of a tentative catalytic cycle for intramolecular hydroamination/cyclisation (IHC) of 4,5-hexadien-1-ylamine (1) by a prototypical cationic [Cp(2)ZrCH(3)](+) zirconocene precatalyst (2) has been examined by employing a gradient-corrected DFT method. The predicted smooth overall reaction energy profile is consistent with the available experimental data, thereby pro...

BACKGROUND/PURPOSE Radio-opacity is an essential attribute of ideal root-end filling materials because it is important for clinicians to observe root canal filling and to facilitate the follow-up instructions. The novel root-end filling material (NRFM) has good cytocompatibility and physicochemical properties but low intrinsic radio-opacity value. To improve its radio-opacity value, three novel...

A series of novel porous zirconium phosphonate-supported 9-amino-9-deoxy-epi-cinchonidines of general formulae Zr(OH)(4-2x)(O(3)PR)(x)·nH(2)O and Zr(HPO(4))(2-x)(O(3)PR)(x)·nH(2)O with the different arm chain lengths (n = 2-6) and mean diameters of approximately 20-40 nm have been prepared as heterogeneous organocatalysts. The different microtextures of zirconium phosphonates were also obtained...

Cell attractive or non-attractive surface properties of polyurethane devices can be controlled by treating them with zirconium tetra(tert-butoxide). This gives reactive interfacial zirconium complex species that can be used subsequently to bond cell attractive peptides such as arg-gly-asp (RGD) or cell non-attractive organics such as polyethylene glycol (PEG) to the device surface. Control of t...

Oxide dispersion strengthened (ODS) steels with different contents of zirconium (denoted as 16Cr ODS, 16Cr-0.3Zr ODS and 16Cr-0.6Zr ODS) were fabricated to investigate the effects of Zr on strengthening mechanism of Al-alloyed 16Cr ODS steel. Electron backscatter diffraction (EBSD) results show that the mean grain size of ODS steels could be decreased by Zr addition. Transmission electron micro...
