TL;DR: In this paper, constant potential reduction was conducted to improve the Cr(VI) removal capacity of magnetite, and the influence of pH, potential and supporting electrolytes including KNO3, KCl, and K2SO4 on the adsorption capacity was also investigated.

TL;DR: In this article, the morphology and structure of bacterial magnetosomes investigated by high-resolution electron microscopy was described, based on direct observation of various kinds of lattice images, the particles were determined to be single crystals with a hexagonal prism shape truncated by 111 planes.
Abstract: Blakemore1 found aquatic bacteria that swim along magnetic lines of force. Such bacteria have small particles of magnetite (magnetosomes) within them2,3 of various shapes3–5. We describe here the morphology and structure of bacterial magnetosomes investigated by high-resolution electron microscopy. From direct observation of various kinds of lattice images, the particles are determined to be single crystals with a hexagonal prism shape truncated by {111} planes. The lattice spacings measured agree with those of magnetite.

TL;DR: In this paper, a simple impregnation of magnetite into palm shell-waste based activated carbon (PBAC) was used for the removal of methylene blue (MB) from an aqueous solution.

TL;DR: In this paper, a new route to synthesize iron oxide nanoparticles inside hydroxyapatite/chitosan bone scaffolds was employed, and the morphology and composition of the synthesized materials were characterized employing scanning electron microscopy and FTIR spectroscopy.
