The current status of knowledge regarding the surfaces of the iron oxides, magnetite (Fe 3 O
4), maghemite (γ-Fe 2 O 3), haematite (α-Fe 2 O 3), and wüstite (Fe 1− x O) is reviewed. The …

Water is perhaps the most important and most pervasive chemical on our planet. The
influence of water permeates virtually all areas of biochemical, chemical and physical …

The development of new catalysts for energy technology and environmental remediation
requires a thorough knowledge of how the physical and chemical properties of a catalyst …

We present a detailed study of static and dynamic magnetic behavior of Fe 3 O 4
nanoparticles with average particle sizes< d> ranging from 5 to 150 nm. Bulk-like properties …

Solvents are widely used in commercial manufacturing and service industries. Despite
abundant precaution, they inevitably contaminate our air, land, and water because they are …

Abstract Natural magnetite (Fe3O4) in the form of single crystal and powder was studied by
laser Raman spectroscopy at various laser powers. The correlations between the power of …

Magnetite particles with an average size of 39 nm and good monodispersity have been
synthesized by coprecipitation at 70° C from ferrous Fe2+ and ferric Fe3+ ions by a (N (CH3) …

Whenever a compound crystal is cut normal to a randomly chosen direction, there is an
overwhelming probability that the resulting surface corresponds to a polar termination and is …

Magnetite nanoparticles of 40 nm in size have been phosphated in orthophosphoric acid.
Large phosphatation rates, equivalent to goethite capacity, have been pointed out, and the …

Chemical reactions occurring at the mineral–water interface are controlled by an interfacial
layer, nanometers thick, whose properties may deviate from those of the respective bulk …
