Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the mol-ecular structure of tris-(di-methyl-amido)-bis-(di-methyl-amine)-zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly...

A sensitive and reproducible method for the direct spectrophotometric determination of zirconium is reported. The method is based on zirconium forms a stable bluish violet colour complex with Chrome Azurol S (CAS) which has maximum absorption at 598 nm at pH 4.2. The complex obeys Beer’s law in the concentration range of 1-7 μg/mL. Detection limit, molar absorptivity and Sandell’s sensitivity w...

Aluminium based nanostructured materials with additions of 0.5, 1 and 1.5 weight% of zirconium have been produced and sintered using the spark plasma sintering technique in order to promote the nucleation of ZrAl3 platelets. The mechanical behaviour of all these nanocomposites was determined by means of the Small Punch Test. Zirconium additions significantly decrease the mechanical properties o...

It is well known that the structure of ZrO2 powder synthesized by low temperature calcination of hydrous zirconia is strongly affected by the nature and properties of precursors. In the present paper, we combined a precipitation/restructuring approach (bottom-up/top-down methodology) to produce zirconium hydroxide nanoparticles that transform into stable nanophasic tetragonal zirconia by low te...

The favourable mechanical properties and high biocompatibility of the newly developed mixed ceramics composed of zirconium oxide and aluminium oxide have continuously extended the scope of their application. Rotating instruments on a zirconium oxide basis are regarded as superior to metal burs in dentoalveolar surgery in terms of favourable temperature effects on the surrounding bone tissue and...

The present paper delves into experimental data to assess the effects of inclusion a zirconium porous medium in emissions laboratory-scale biomass combustor, with focus on particulate matter and volatile organic compounds. While other studies have focused material solid or gaseous emissions, this research is volatiles, their capture storage. A novel sampling train for volatiles has been designe...

The structures of free-standing zirconium nanowires with 0.6−2.8 nm in diameter are systematically studied by using genetic algorithm simulations with a tight-binding many body potential. Several multi-shell growth sequences with cylindrical structures are obtained. These multi-shell structures are composed of coaxial atomic shells with the threeand four-strands helical, centered pentagonal and...
