Zero valent iron mediated degradation of the pharmaceutical diazepam

Chemosphere, 2012
Parameters that influence the zero valent iron mediated degradation of the pharmaceutical diazepam (DZP) were evaluated including the iron concentration and its pre-treatment, the effect of complexation with EDTA and oxic versus anoxic condition. It was observed that acid pre-treatment of iron particles is important for degradation efficiency and that ...

Synthesis of core-shell nanoparticles for the removal of toxic pollutants in aqueous medium [PDF]

, 2018
In this work two active photo-catalysts were synthetized and tested for the removal of methylene blue and arsenic in aqueous solutions. The two catalysts (Fe3O4/SiO2/TiO2-Al and Fe3O4-SiO2/Zr-TiO2) were characterized by nano-size, guaranteeing a large ...

A large energy-gap oxide topological insulator based on the superconductor BaBiO3

, 2013
Mixed-valent perovskite oxides based on BaBiO3 (BBO) are, like cuperates, well-known high-Tc superconductors. Recent ab inito calculations have assigned the high-Tc superconductivity to a correlation-enhanced electron--phonon coupling mechanism ...

Magnetic fluctuations and superconducting properties of CaKFe4As4 studied by 75As NMR [PDF]

, 2017
We report $^{75}$As nuclear magnetic resonance (NMR) studies on a new iron-based superconductor CaKFe$_4$As$_4$ with $T_{\rm c}$ = 35 K. $^{75}$As NMR spectra show two distinct lines corresponding to the As(1) and As(2) sites close to the K and Ca layers,

Effective acetalization of furfural catalyzed by Fe‐ and Co‐oxalates: impact of alcohols structure on products composition

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Fe‐, Co‐, and FeCo‐oxalates supported on silica gel (5 wt% metal load) were synthesized, characterized, and tested for the first time in solvent‐free furfural (FF) acetalization with C1–C8 alcohols at 70–170 °C under both conventional and microwave (MW)‐assisted conditions. The interaction of FF with linear C1–C4 alcohols yielded pincer‐shaped
