Application of polyoxometalate-ionic liquids (POM-ILs) in dye-sensitized solar cells (DSSCs)

open access: yesMaterials Letters: X, 2020
Polyoxometalates (POMs) as anionic metal oxides are promising candidates for application in dye-sensitized solar cells (DSSCs) due to their peculiar properties including a reversible and multi-electron redox behavior.

The molybdenum blue reaction for the determination of orthophosphate revisited: Opening the black box [PDF]

open access: yes, 2015
The molybdenum blue reaction, used predominantly for the determination of orthophosphate in environmental waters, has been perpetually modified and re-optimised over the years, but this important reaction in analytical chemistry is usually treated as ...

Carbon Nanomaterial–Phosphomolybdate Composites for Oxidative Electrocatalysis

open access: yesChemElectroChem, 2014
AbstractNovel hybrid nanocomposites based on the immobilisation of tetrabutylammonium salts of phosphomolybdates (PMo12, PMo11, PMo11V, and PMo10V2) on single‐walled carbon nanotubes or graphene flakes were prepared. Glassy carbon electrodes modified with carbon nanocomposites produce cyclic voltammograms that are consistent with surface‐confined redox

Redox‐Mediating Mo2C Nanoparticles Confined Within Nitrogen‐ and Phosphorus‐Codoped Amorphous Carbon Matrix for Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.
A multifunctional interlayer composed of Mo2C nanoparticles embedded in a nitrogen‐ and phosphorus‐doped amorphous carbon matrix on graphene is developed via electrostatic self‐assembly and thermal transformation. The resulting architecture suppresses the shuttle effect, improves electrical conductivity, and facilitates redox conversion kinetics ...

Comparative Study of Microwave and Ultrasound‐Assisted Extraction of Phosvitin From Egg Yolk

open access: yesFood Science &Nutrition, Volume 14, Issue 3, March 2026.
Microwave‐assisted extraction produced phosvitin with greater purity and recovery compared to ultrasound‐based methods. An increase in microwave power and processing time was positively correlated with both phosvitin purity and HDL removal efficiency, as confirmed by FT‐IR analysis and SDS‐PAGE electrophoresis profiles.

THE PHOSPHOMOLYBDIC ACID-TOCOPHEROL COLOUR COMPLEX

open access: yes, 1956
The reaction of phosphomolybdic aicd with tocopherol (vitamin-E)has been investigated and the resultant complex studied. The blue complex was isolated in solid form and a preliminary study conducted on the nature of the complex formation. Based on experimental evidence, a tentative mode of formation has been proposed, suggesting the condensation of ...
