Abstract
Official abstract text for this publication.
Nanowire synthesis and one dimensional nanowire synthesis of titanates and cobaltates. Exemplary titanates and cobaltates that are fabricated and discussed include, without limitation, strontium titanate (SrTiO 3 ), barium titanate (BaTiO 3 ), lead titanate (PbTiO 3 ), calcium cobaltate (Ca 3 Co 4 O 9 ) and sodium cobaltate (NaCo 2 O 4 ).
First claim
Opening claim text (preview).
What is claimed is: 1. A process for forming nanowires, the process comprising: combining potassium titanate nanowires with a solution comprising KOH mixed with strontium nitrate, barium nitrate, or lead nitrate to create a combination; and processing the combination by heating the combination at a temperature above 200° C. for at least one day to form an end product. 2. The method of claim 1 , wherein the processing further comprises: washing the end product after the heating step by rinsing the end product with deionized water. 3. The method of claim 2 , wherein processing the combination further comprises separating the end product from solution. 4. The method of claim 1 , wherein the potassium titanate nanowires are formed by mixing nanoparticles containing titanium oxide with a solution containing KOH to create a precursor mixture; and heating the mixture.
