Surface Modification of SnO2 with Phosphonic Acids

Journal of Chemistry, 2017
The aim of the present work was the study of phosphonic acids grafting on the surface of SnO2 at different molar ratios. In this paper we describe the functionalization of SnO2 surfaces with phosphonic acids RPO(OH)2. The surface modification process was

Synthesis of phosphonic acid ligands for nanocrystal surface functionalization and solution processed memristors [PDF]

, 2018
Here, we synthesized 2-ethylhexyl, 2-hexyldecyl, 2-[2-(2-methoxyethoxy)ethoxy]ethyl, oleyl, and n-octadecyl phosphonic acid and used them to functionalize CdSe and HfO2 nanocrystals.

Styrene-divinylbenzene copolymer grafted with phosphonic acid dialkylesters [PDF]

Journal of the Serbian Chemical Society, 2004
The functionalization of a crosslinked chloromethylated polystyrene 8% divinylbenzene copolymer with phosphonic ester groups is detailed. The reacton conditions were studied in order to determine the optimal conditions for obtaining only diesters.

Is the detection of phosphonic and ethyl-phosphonic acid in organic wines an evidence of fosetyl-Al application in organic vineyards?

Applied Food Research
Over the last decade, the detection of phosphonic acid in organic food, a residue of plant protection products not permitted by Regulation (EU) 2021/1165, has become a critical issue for European organic producers. Approximately 10 % of EU irregularities

Delayed hepatic uptake of multi-phosphonic acid poly(ethylene glycol) coated iron oxide measured by real-time Magnetic Resonance Imaging

, 2016
We report on the synthesis, characterization, stability and pharmacokinetics of novel iron based contrast agents for magnetic resonance imaging (MRI). Statistical copolymers combining multiple phosphonic acid groups and poly(ethylene glycol) (PEG) were ...

Interaction of solid organic acids with carbon nanotube field effect transistors [PDF]

, 2006
A series of solid organic acids were used to p-dope carbon nanotubes. The extent of doping is shown to be dependent on the pKa value of the acids. Highly fluorinated carboxylic acids and sulfonic acids are very effective in shifting the threshold voltage

Platinum(II) complexes containing ferrocene-derived phosphonate ligands; synthesis, structural characterisation and antitumour activity [PDF]

, 2001
Platinum ferrocenyl–phosphonate complexes, containing four-membered Pt---O---P(O)---O rings, have been synthesised by the reactions of cis-[PtCl₂(PPh₃)₂] with the ferrocene-derived phosphonic acids Fc(CH₂)nP(O)(OH)₂(n=0–2) [Fc=(η⁵-C₅H₄)Fe(η⁵-C₅H₅)] and 1,
