Hematite is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. In this book, the authors present current research in the study of the sources, properties and applications of hematite. Topics discussed include nanostructured hematite for solar driven hydrogen generation; reactions at the hematite surface with Fe(II) and environmental contaminants; the catalytic properties of sulfated hematite in toluene disproportionation; hematite nanotubes and nanorings; and the synthesis, characterization and photocatalytic property of nanostructured hematite.
Hematite (α-Fe2O3), the stable oxide of iron, is a major constituent of soils, rocks and the earth's crust. It has unique magnetic properties that make it the prototype for the class of materials known as canted antiferromagnets. This book has no equivalent. The mean-field theory is treated in detail, and thus the book is a useful text for students mastering this general method. Information obtained by a wide variety of experimental methods is provided. These techniques include x-ray and neutron diffraction; electron magnetic resonance; Mössbauer spectroscopy; and thermal, optical, electrical and elastic measurements.

Hematite is a young vampire who is trying to find her way. As a member of the illustrious Blackwood family, she faces pressure to conform to high society standards, but such grandstanding isn’t for her. And neither is drinking blood—she’d rather have vegetable soup! So it is that she opts for the more diverse Wolven School, rather than joining the ranks of her fellow vampires at the Diaemus Academy. Being different can be hard, though, and doesn’t always help to make friends. Luckily for Hematite, she has her poetry, as well as Drunela—a draugr who won’t let their differences keep them apart—and Emile, a human boy fascinated by the occult who would just love to take a peek at the Blackwood’s private library. Unfortunately, bridging societal divides isn’t always easy, and can lead to terrible consequences...
