Stable Supported Lipid Bilayers on Zirconium Phosphonate Surfaces
Langmuir, 2009Supported lipid bilayers that can fully represent biological cell membranes are attractive biomimetic models for biophysical and biomedical applications. In this study, we develop a new approach to engineering stable supported lipid membranes and demonstrate their utility for the study of protein-membrane interactions.

Polyaniline–zirconium phosphonate composites: Thermal stability and spectroscopic study
, 2020Microcomposites of zirconium 4-sulfophenylphosphonate and polyaniline (PANI) and zirconium 4-carboxyphenylphosphonate and PANI were prepared and their thermal decomposition in air and in nitrogen was studied by thermogravimetry.

Journal of Molecular Catalysis A: Chemical, 1998
Abstract Vapour phase catalysis of the dehydration of cyclohexanol, nerol and geraniol and of the thermal rearrangement of α -pinene by unsubstituted zirconium phosphates has been compared with similar catalysis effected by organically pillared zirconium phosphates and with catalysis by alumina. Many of the observed differences in reaction rates can

This contribution presents a survey of the various aspects of the chemistry of Zr phosphonates, throughout 30 years of activity of the Laboratory of Inorganic Chemistry of Perugia on this topic. These inorganic–organic compounds are characterized by a very low solubility and chemical robustness, and their structure and reactivity can be easily ...

Zirconium−Phosphonate Monolayers with Embedded Disulfide Bonds
Langmuir, 2003Disulfides are chemically and electrochemically reactive functional groups that could be useful for ultra-high-resolution patterning of self-assembled monolayer films (SAMs) by atomic force microscopic (AFM) anodization. Zirconium−organophosphonate monolayers that contain embedded disulfide bonds were prepared by sequential deposition of Zr4+ and H2PO3-

Selective Capture of Phosphopeptides by Zirconium Phosphonate-Magnetic Nanoparticles
2011Immobilized metal affinity chromatography is a widely used method for the enrichment of phosphopeptides from proteolytic digests prior to mass spectrometric analysis. Here, we describe the selective enrichment of phosphopeptides from tryptic digests of proteins (α- and β-caseins) by zirconium phosphonate-magnetic Fe(3)O(4)/SiO(2) (core/shell ...

Catalyst design of two-dimensional zirconium phosphonates
Journal of Molecular Catalysis, 1992Abstract Zirconium phosphates or phosphonates, whose compounds have the general formula Zr(O3PR)2, can be obtained in crystalline forms with various layered structures. The preparation and characterization of two-dimensional zirconium phosphonate derivatives have been investigated.
