Self-Assembly of Highly Stable Zirconium (IV) Coordination Cages with Aggregation Induced Emission (AIE) Molecular Rotors for Live-Cell Imaging.

Angewandte Chemie, 2019
Although supramolecular coordination complexes have demonstrated outstanding host-guest chemistry in solution or solid state, the low structural stability, weak fluorescence emission, and cell viability in aqueous solutions have limited their ...

Zirconium and Zirconium Alloy Castings

2008
Abstract This article describes typical foundry practices used to commercially produce zirconium castings. The foundry practices are divided into two sections, namely, melting and casting. The article discusses various melting processes, such as vacuum arc skull melting, induction skull melting, and vacuum induction melting, and various ...

The precipitation of γ-zirconium hydride in zirconium

Acta Metallurgica, 1978
Abstract A mechanism for the precipitation of γ-zirconium hydride in zirconium is presented which does not require the diffusion of zirconium. The transformation is completed by shears caused by 1 3 〈1010〉 Shockley partial dislocations on alternate zirconium basal planes, either by homogeneous nucleation or at lattice imperfections ...

Performance of Zirconium and Zirconium Alloys in Organics

Journal of Testing and Evaluation, 1996
Abstract Zirconium and its alloys are well known for their corrosion resistance in a broad range of inorganic and organic media. They have played a key role in advancing the production technologies of urea and formic, acetic, hydroxyacetic, lactic, and methacrylic acids, methyl methacrylate, rayon, alcohols, and phenolic resins, etc ...

The precipitation of zirconium hydride in zirconium and zircaloy-2

Journal of Nuclear Materials, 1972
Abstract The precipitation of zirconium hydride in iodide zirconium and zircaloy-2 has been studied using, primarily, thin foil electron microscopy. The precipitate crystal structure and distribution has been found to be a function of heat treatment procedure.

Determination of the zirconium site in zirconium-substituted Nd2Fe14B

Journal of Applied Physics, 1993
We report a direct determination of the Zr site in pseudoternary alloys with a nominal composition of Nd1.6Zr0.4Fe14B using extended x-ray absorption fine structure (EXAFS). Comparing the Zr EXAFS from these alloys to the Y EXAFS from Y2Fe14B and the Fe EXAFS from Nd2Fe14B reveals that the local Zr and Y environments are nearly identical, and quite ...

Bridging exosome and liposome through zirconium-phosphate coordination chemistry: a new method for exosome detection.

Chemical Communications, 2019
We have proposed a new exosomes-zirconium-liposomes sandwich structure to detect exosomes by using zirconium-phosphate coordination chemistry. The combined use of the intrinsic property of phosphate in both exosomes and liposomes as well as zirconium ...

Corrosion of Zirconium Alloys Used for Nuclear Fuel Cladding

, 2015
During operation, nuclear fuel rods are immersed in the primary water, causing waterside corrosion and consequent hydrogen ingress. In this review, the mechanisms of corrosion and hydrogen pickup and the role of alloy selection in minimizing both ...
