Abstract:
Phosphoric acid has received the most attention as a choice of electrolyte for a high-temperature proton exchange membrane fuel cell (HT-PEMFC). Phosphoric acid has many attractive properties such as high anhydrous conductivity, good compatibility with hydrocarbon membranes, and thermal stability [1], which enables high fuel cell performance under anhydrous and elevated operating temperatures (140-180 oC) [2-3]. However, phosphoric acid has undesirable properties such as high catalyst poisoning, high evaporation rate at > 200 oC, and low acid retention from the doped membrane. Alkyl phospho

Abstract:
The combined benefits of moisture-stable phosphonic acids and mesoporous silica materials (SBA-15 and MCM-41) as large-surface-area solid supports offer new opportunities for several applications, such as catalysis or drug delivery. We present a comprehensive study of a straightforward synthesis method via direct immobilization of several phosphonic acids and phosphoric acid esters on various mesoporous silicas in a Dean–Stark apparatus with toluene as the solvent. Due to the utilization of azeotropic distillation, there was no need to dry phosphonic acids, phosphoric acid esters, solvents, or

Abstract:
Ion-pair high-temperature polymer electrolyte membranes (HT-PEMs) paired with phosphonic acid ionomer electrode binders have substantially improved the performance of HT-PEM electrochemical hydrogen pumps (EHPs)1, 2 and fuel cells3. Recently, blending poly(pentafluorstyrene-co-tetrafluorostyrene phosphonic acid) (PTFSPA) with NafionTM improved ionomer conductivity under anhydrous conditions in the temperature range of 100 °C to 250 °C. Using the said polymer blend as an electrode binder resulted in a 2 W.cm-2 peak power density of fuel cells4 at 240 °C (a HT-PEM fuel cell record). However, muc

The phosphonic acid functional group, which is characterized by a phosphorus atom bonded to three oxygen atoms (two hydroxy groups and one P=O double bond) and one carbon atom, is employed for many applications due to its structural analogy with the phosphate moiety or to its coordination or supramolecular properties. Phosphonic acids were used for their bioactive properties (drug, pro-drug), for bone targeting, for the design of supramolecular or hybrid materials, for the functionalization of surfaces, for analytical purposes, for medical imaging or as phosphoantigen.

The interface of a zinc-terminated polar zinc oxide surface (0002) with a series of chemisorbed fluorinated benzylphosphonic acids has been studied using density functional theory. The calculations indicate that there is a substantial change in the binding energies and work function modification depending on the binding motif. The results also indicate that there is a pronounced difference in the magnitude and trends of the factors determining the total change in work function. The oxygen core-level binding shifts have been calculated and compared to available experimental data.

Abstract:
Abstract Sulfide scales, such as ZnS or FeS, are not as common as carbonate and sulfate scales, but an effective way to control them has not been fully developed. Solubility of ZnS and FeS is extremely low. As a result, it does not require a great amount of metal ions to precipitate sulfide scales. Once they are deposited on the surface, it is difficult to remove them due to their low solubility. The objectives of this study are to identify more effective and efficient chemicals for prevention and removal of sulfide scale deposits and to understand the sulfide scale control mechanism of these

Abstract:
Abstract A new organic additive for ferrous metal corrosion has been developed, a hydroxy-phosphonic acid (HPA) with carboxylate functionality. Formulations containing this new additive have shown good performance in cooling water simulation testing from pH 8 to 9 and system calcium levels of 300 to 700 ppm as calcium carbonate. Electrochemical investigations were used to develop hypotheses regarding its mechanisms of protection. These hypotheses were used to improve the cost performance of these treatment programs.

Abstract:
The objective of the research was to establish whether phosphoric acid treatment of line pipe should routinely be undertaken before the application of FBE coatings where chloride contamination is not present; to determine the levels of treatment which enhance or cause deterioration on the steel surface; to establish any synergism that may exist between specific FOE coatings and phosphoric acid treatment; to determine if coating performance correlates to residual phosphate on the steel surface, and to provide end-user companies with data to enable the proper selection of surface treatments for
