Polyoxometalates as antitumor agents: Bioactivity of a new polyoxometalate with copper on a human osteosarcoma model
(Elsevier, 2014-10-05)
Polyoxometalates (POMs) are early transition metal oxygen anion clusters. They display interesting biological effects mainly related to their antiviral and antitumor properties. On the other hand, copper compounds also ...
Temperature and exposure time-dependent scintillation of Eu(III) polyoxometalate under X-ray excitation
(2018-11-01)
Sodium decatungstoeuropate, Na9[Eu(W5O18)2]·14H2O, is a promising material to convert X-ray into visible light. In this work, temperature and exposure time-dependent scintillation of the Na9[Eu(W5O18)2]·14H2O sample under ...
Novel Polyoxometalate- Ionic Liquid with Antibacterial and Antifungal Properties. Feasibility of Its Implementation As a Multifunctional Thin Coating
(American Institute of Chemical Engineers, 2019)
The synthesis of hybrid materials, combining the properties of organic and inorganic components, results in composites with unique physical and chemical features. Polyoxometalates (POMs), i.e. inorganic anionic molecular ...
Transition metal-modified polyoxometalates supported on carbon as catalyst in 2-(methylthio)-benzothiazole sulfoxidation
(Springer India, 2015-02-14)
Polyoxometalates with lacunary Keggin structure modified with transition metal ions [PW11O39M(H2O)]5−, where M= Ni2+, Co2+, Cu2+ or Zn2+, were synthesized and supported on activated carbon to obtain the PW11MC catalysts. ...
Increased in vitro Anti-HIV Activity of Caffeinium-Functionalized Polyoxometalates
(Wiley VCH Verlag, 2021-05)
Polyoxometalates (POMs), molecular metal oxide anions, are inorganic clusters with promising antiviral activity. Herein we report increased anti-HIV-1 activity of a POM when electrostatically combined with organic ...
Multimetallic porphyrins/polyoxotungstate modified electrodes by layer-by-layer method: Electrochemical, spectroscopic and morphological characterization
(PERGAMON-ELSEVIER SCIENCE LTD, 2012)
This work describes the formation of modified electrodes layer-by-layer assembly of a mu-{meso-5,10,15,20-tetra(pyridyl)porphyrin}terrakis{bis(bipyridine)chloride ruthenium(II)} coordinated with Zn(II) and Mn(III) in its ...
Polyoxometalate cluster [v12b18o60h6] functionalized with the copper(ii) bis-ethylenediamine complex
(ELSEVIER SCIENCE SA, 2011)
