Black Iron Oxide Coated Thin Filler Pigments.

Removal of Fe2+ from Aqueous Solution Using Manganese Oxide Coated Zeolite and Iron Oxide Coated Zeolite

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Synthesis and Application of Carbon–Iron Oxide Microspheres’ Black Pigments in Electrophoretic Displays

Carbon-iron oxide microspheres' black pigments (CIOMBs) had been prepared via ultrasonic spray pyrolysis of aqueous solutions containing ferrous chloride and glucose. Due to the presence of carbon, CIOMBs not only exhibited remarkably acid resistance, but also could be well dispersed in both polar solvents and nonpolar solvent. Finally, dispersions of hollow CIOMBs in tetrachloroethylene had su...

Filler and Coating Pigments for Papermakers

Historians attribute the Egyptians in the Nile Delta with preparing the first type of paper, from a marsh grass called Cyperus papyrus. They cut the plant’s stem into thin strips, softened them in the river, and then pounded them into thin sheets that were then left to dry in the sun. The resulting sheets were ideal for writing on, and Egyptians, Greeks, and Romans used them for record keeping,...

Biocompatibility of chitosan-coated iron oxide nanoparticles with osteoblast cells

BACKGROUND Bone disorders (including osteoporosis, loosening of a prosthesis, and bone infections) are of great concern to the medical community and are difficult to cure. Therapies are available to treat such diseases, but all have drawbacks and are not specifically targeted to the site of disease. Chitosan is widely used in the biomedical community, including for orthopedic applications. The ...
