Metastable Crystalline Cobalt Iron Oxide Nano-Flakes with Antiferromagnetic/Ferrimagnetic Composition Mosaicity. [PDF]

Angew Chem Int Ed Engl
Through precursor co‐precipitation and mild calcination, a metastable interface‐rich cobalt iron oxide with unique magnetic properties was synthesized. Due to compression of the lattice parameter in the iron‐rich phase and the multitude of interfaces, an exchange bias was created, usually not known for such powder samples.

Synthesis and Anchoring of Antineoplastic Ferrocene and Phthalocyanine Derivatives on Water‐Soluble Polymeric Drug Carriers Derived from Lysine and Aspartic Acid

Metal-Based Drugs, Volume 2008, Issue 1, 2008., 2008
The general synthetic strategy towards water‐soluble biodegradable drug carriers and the properties that they must have are discussed. The syntheses of water‐soluble biodegradable copolymers of lysine and aspartic acid as potential drug‐delivering devices, having amine‐functionalised side chains are then described. Covalent anchoring of carboxylic acid

Determinação simultânea de cobalto e níquel [PDF]

Química Nova, 1998
The simultaneous determination of cobalt and nickel is a classical analytical problem. A great number of reagents associated with several techniques of analysis have been applied to achieve this determination. In this review 117 references, which appeared between 1996-1980, are described and classified according to the technique applied.
