摘要:A technique to synthesize complex oxide ceramic powders which offers advantages of both the coprecipitation and sol-gel routes while doing away with the disadvantages is disclosed. Namely, the ability to achieve chemical homogeneity and crystallite size on the namometer length scale at a nonprohibitive cost is provided by the disclosed method. In one embodiment of the invention, a method for the synthesis of a mixed metal oxide powder is provided including (a) combining a liquid absorbent resin with at least one solution selected from the group consisting of solutions containing at least one organo-metallic compound and solutions containing at least one metallic salt compound, such that at least two metals are present in the liquid absorbent resin after the combining is completed; (b) after the combining, allowing the liquid absorbent resin to swell and gel and thereby form a swollen gel; (c) preparing a precursor material by changing at least one of the pH and temperature of the swollen gel; (d) pyrolyzing the precursor material to form a pyrolyzed precursor material; and (e) calcining the pyrolyzed precursor material to form a mixed metal oxide powder.

摘要:A facile synthesis route for preparing SBA-15 silica of platelet shape and very short mesochannels was developed by introducing a small amount of Zr(IV) ions in the first synthesis solution. The synthesis route can be easily extended to prepare SBA-15 materials with various organic functional groups in one pot.

标题:Synthesis and use of therapeutic metal ion containing polymeric particles
发明人：PETROS ROBBY A

摘要:Therapeutic particles contain metal ions and are characterized by the use of unique ligand sets capable of making the metal ion complex soluble in biological media to induce selective toxicity in diseased cells. The particles may comprise a polymeric base particle, at least one pharmaceutically active metal ion, including metal ions from more than one metal element, a ligand that is covalently attached to the polymeric base particle and attached to the metal ion via a stimuli-responsive bond, and a cell targeting component. When the metal ion-containing particle enters a pre-defined environment, the ligands binding the metal to the particle are broken, triggering release of the free metal ion while the original ligands remain covalently bound to the particle.
