Thermal desorption of dimethyl methylphosphonate from MoO3 [PDF]

open access: yes, 2017
Organophosphonates are used as chemical warfare agents, pesticides, and corrosion inhibitors. New materials for the sorption, detection, and decomposition of these compounds are urgently needed.

Tuning of noble metal work function with organophosphonate nanolayers [PDF]

open access: greenApplied Physics Letters, 2014
We demonstrate that weak chemical interactions between untethered moieties in molecular nanolayers on metal surfaces can strongly influence the effective work function Φeff. Electron spectroscopy shows that nanolayers of mercaptan-anchored organophosphonates on Au and Pt decrease Φeff.

A cobalt arylphosphonate MOF – superior stability, sorption and magnetism [PDF]

open access: yes, 2019
We report a novel metal-organic framework (MOF) based on a cobalt arylphosphonate, namely, [Co2(H4-MTPPA)]·3NMP·H2O (1·3NMP·H2O), which was prepared solvothermically from the tetrahedral linker tetraphenylmethane tetrakis-4-phosphonic acid (H8-MTPPA) and

Poly[aqua(μ-vinyl­phospho­nato)cadmium] [PDF]

open access: yes, 2011
The title compound, [Cd(C2H3O3P)(H2O)]n, was obtained from vinyl­phospho­nic acid and cadmium nitrate. The vinyl groups project into the inter­lamellar space and the structure is held together via van der Waals forces.

Experimental Design: Application to the Development of a Treatment to Inhibit the Deposition of Barium Sulfate Liable to Be Formed in Enhanced Oil Recovery by Waterflooding Planification d'expériences : application à la mise au point d'un traitement inhibiteur du depôt de sulfate de baryum susceptible de se former en récupération assistée du pétrole par injection d'eau

open access: yesOil & Gas Science and Technology, 2006
For technical and economic reasons, waterflooding is the most widely-used method in enhanced oil recovery [1]. In many situations, unfortunately, the formation water is incompatible with the injection water.

Selective desorption of organophosphonates on chemically functionalized titanium by Direct Laser Patterning [PDF]

open access: yes, 2014
Surface functionalization based on organophosphonate molecules and Direct Laser Patterning (DLP) technique both allow to design chemically patterned titanium surfaces devoted to biomaterial engineering.

Structural variations in layered alkaline earth metal cyclohexyl phosphonates [PDF]

open access: yes, 2009
Two series of alkaline earth metal cyclohexyl phosphonates, M(C6H11PO3H)2(H2O) (M = Ca, Sr and Ba) (1-3) and M(C6H11PO3)(H2O) (M = Mg, Ca, Sr, and Ba) (4-7) have been synthesized under mild reaction conditions.

Organophosphonate utilization by the wild-type strain of Pseudomonas fluorescens [PDF]

open access: yesApplied and Environmental Microbiology, 1992
The wild-type strain of Pseudomonas fluorescens was found to utilize a range of structurally diverse organophosphonates as its sole carbon or nitrogen sources. Representative compounds included aminoalkylphosphonates, hydroxyalkylphosphonates, oxoalkylphosphonates, and phosphono dipeptides.
