Films of highly oriented alpha-zirconium phosphate and polyaniline-intercalated zirconium phosphate with controllable thickness in the micrometer range were grown anodically on Pt electrodes. To optimize the electrodeposition conditions, the exfoliation of alpha-zirconium phosphate by tetrabutylammonium (TBA) salts was investigated in several nonaqueous solvents. Acetonitrile was found to be th...

Herein we detail the synthesis and characterisation of a series of zirconium compounds featuring the bis(amido)silyl ligand [(i)Pr2Si(NDipp)2](2-) (Dipp = 2,6-diisopropylphenyl). The functionalisation of bis(amido)silyl zirconium halide complexes with a variety of nucleophiles, such as LiNMe2, LiBH4 and MeLi, was explored and the resulting products showed a propensity to form anionic zirconate ...

BACKGROUND Some metallic compounds, especially of zirconium, can cause cell mediated granulomatous inflammation of the skin. Pigment granules containing compounds of aluminium, silicon, and titanium have been observed within macrophages in the wall of the small intestine in health and in Crohn's disease. Zirconium compounds can be ingested in toothpaste. AIM To determine in a pilot study if g...

Coatings of zirconium compounds are used in a wide variety fields, yet an understanding and descriptions deposition mechanisms scant the public literature. The for metallic zirconium, ZrC, ZrN, ZrO2, ZrB2, silicides discussed based on direct vapor research those where possible or compared to complementary titanium systems when is lacking. Both inorganic organometallic discussed. As class compou...

2-amino-substituted ketones react with α-methylene ketones under solvent-free conditions at 90 °c in thepresence of a catalytic amount of zirconium dodecylphosphonate to create the corresponding quinolinesin excellent yields. this procedure recommends numerous advantages such as easy work-up, use of mild,reusable and safe catalyst, short reaction timeand high yields. the new compounds have been...

Many materials that are usually found in the earth's crust contain small but measurable amount of naturally occurring radioactivity (NORM). Some particular ores contain natural radionuclide at levels much higher those usually present in earth's crust; and are also subject to radioisotope enrichment, during technological process, known as technologically enhanced natural radioactivity (TENORM). ...

An aggregation-induced emission (AIE) probe, possessing a quaternary tetraphenylethene (TPEN) cation, was successfully intercalated into layered α-zirconium phosphate (α-ZrP) nanosheets by ion-exchange. The hybrid materials emit strong blue emissions in aqueous solution which can be used as an effective fluorescence label for HeLa cells.
