Organophosphonate metabolism by a moderately halophilic bacterial isolate [PDF]

open access: yesFEMS Microbiology Letters, 2000
A Gram-negative halophile isolated from soil beneath a road gritting salt pile grew optimally at 10% (w/v) NaCl and was shown most likely to be Chromohalobacter marismortui or Pseudomonas beijerinckii on the basis of 16S rRNA analysis. The strain utilised phosphonoacetate, 2-aminoethyl-, 3-aminopropyl-, 4-aminobutyl-, methyl- and ethyl-phosphonates as ...

Semiconductive microporous hydrogen-bonded organophosphonic acid frameworks [PDF]

open access: yesNature Communications, 2020
Abstract Herein, we report a semiconductive, proton-conductive, microporous hydrogen-bonded organic framework (HOF) derived from phenylphosphonic acid and 5,10,15,20‐tetrakis[ p ‐phenylphosphonic acid] porphyrin (GTUB5).

Pore-Size Tunable Mesoporous Zirconium Organophosphonates with Chiral l-Proline for Enzyme Adsorption [PDF]

open access: yes, 2016
Mesoporous zirconium organophosphonates with a tunable mesopore (pore diameter:  from 4.8 to 16.3 nm) were synthesized through co-condensation of ZrCl4 and 1-phosphomethylproline (H3PMP) with the aid of organic additives in the presence of an anionic ...

An Organophosphonate Strategy for Functionalizing Silicon Photonic Biosensors [PDF]

open access: yesLangmuir, 2012
Silicon photonic microring resonators have established their potential for label-free and low-cost biosensing applications. However, the long-term performance of this optical sensing platform requires robust surface modification and biofunctionalization.

The use of a 2-aminoethylphosphonate by the mesophilic Penicillium commune strain

open access: yesBioTechnologia, 2018
The recognition of the breakdown mechanisms of naturally occurring phosphonates is very important to understand the distribution mechanisms of their synthetic derivatives that are deposited in large amounts in the environment – for example, N ...

The Prospect of Selective Recognition of Nerve Agents with Modular Basket-like Hosts. A Structure-Activity Study of the Entrapment of a Series of Organophosphonates in Aqueous Media [PDF]

open access: yes, 2013
We designed, prepared, and characterized three cup-shaped cavitands 1-3 for trapping organophosphonates (O=PR(OR')(2), 118-197 A3) whose shape and size correspond to G-type chemical warfare agents (132-186 A(3)).

Synthesis of Mesostructured and Mesoporous Aluminum Organophosphonates Prepared by Using Diphosphonic Acids with Alkylene Groups [PDF]

open access: yes, 2016
Mesostructured and mesoporous aluminum organophosphonates (AOPs) with 2-D hexagonal structures (AOP-2) can be synthesized by using alkylene diphosphonic acids in the presence of alkyltrimethylammonium (CnTMA) surfactants.

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.
