Characterization and surface reactivity of ferrihydrite nanoparticles assembled in ferritin.
Ferrihydrite nanoparticles with nominal sizes of 3 and 6 nm were assembled within ferritin, an iron storage protein. The crystallinity and structure of the nanoparticles (after removal of the protein shell) were evaluated by high-resolution transmission electron microscopy (HRTEM), atomic force microscopy (AFM), and scanning tunneling microscopy (STM). HRTEM showed that amorphous and crystallin...
متن کاملSynthesis of BiVO4 nanoparticles by the co-precipitation method and study the crystal structure, optical and photocatalytic properties of them
In this paper, the bismuth vanadate (BiVO4) nanoparticles were synthesized at 600 °C calcination temperature by co-precipitation method. To study the crystal structure, morphology, optical and photocatalytic properties of the samples, the X-ray diffraction analysis, field emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy and ult...
متن کاملA novel approach to quantify different iron forms in ex-vivo human brain tissue
We propose a novel combination of methods to study the physical properties of ferric ions and iron-oxide nanoparticles in post-mortem human brain, based on the combination of Electron Paramagnetic Resonance (EPR) and SQUID magnetometry. By means of EPR, we derive the concentration of the low molecular weight iron pool, as well as the product of its electron spin relaxation times. Additionally, ...
متن کاملCo-precipitation Synthesis of Zinc Oxide (ZnO) Nanoparticles by Zinc Nitrate Precursor
Nanostructured zinc oxide (ZnO) materials have received considerable interest from scientists due to their remarkable performance in electronics, optics and photonics. ZnO nanoparticles were synthesized by co-precipitation method. ZnO nanoparticles were synthesized using Zn(NO3)3 and K2CO3 precursors. The structure of the obtained product was confirmed by the powder X-ray diffraction (XRD) anal...
