Highly Attrition-Resistant Zinc Oxide-Based Sorbents for H2S Removal by Spray-Drying Technique

Highly Attrition Resistant Zinc Oxide-Based Sorbents for H2S Removal by Spray Drying Technique

Preparation and characterization of hydroxyapatite-coated iron oxide particles by spray-drying technique.

Magnetic particles of iron oxide have been increasingly used in medical diagnosis by magnetic resonance imaging and in cancer therapies involving targeted drug delivery and magnetic hyperthermia. In this study we report the preparation and characterization of iron oxide particles coated with bioceramic hydroxyapatite by spray-drying. The iron oxide magnetic particles (IOMP) were coated with hyd...

Taste masking of roxithromycin by spray drying technique.

The spray drying technique was used to obtain the roxithromycin containing microcapsules with high taste masking efficiency. Eudragit L30D-55 was chosen as a barrier coating. The taste was evaluated by an electronic tongue, and taste-masking effect in water lasted at least several dozen hours.

Properties of Nanostructured Hydroxyapatite Prepared by a Spray Drying Technique

In previous studies nano sized hydroxyapatite (HA) particles were prepared by solgel or precipitation methods, in which the products were washed by aqueous or non-aqueous liquids to remove impurities or undesired components. The washing is know to modify the surfaces of the cystalline particles. This study evaluated properties of nano HA materials prepared by a spray drying method in which the ...

Endotoxin removal by affinity sorbents.

Affinity sorbents and detoxification strategies are described to remove different amounts of endotoxin. Advantages and disadvantages of the employed ligands are discussed and it is shown that both electrostatic and hydrophobic interactions contribute to the association of ligands and endotoxins. Furthermore, the flexibility of the ligand is more important than an exact structural match between ...
