Carbon Combustion Synthesis of Lithium Cobaltate

Hobosyan M., Mamyrbaeva Y., Martirosyan K.S., University of Texas at Brownsville, US

We recently developed a novel process Carbon Combustion Synthesis of Oxides (CCSO) to rapidly produce high purity, submicron, porous powders of complex oxides. The crystalline LiCoO2 nanoparticles were synthesized by carbon combustion synthesis, and characterized [...]

Spherically symmetric oxidation model of aluminum nanoparticles

Ramazanova Z., Zyskin M., Martirosyan K.S., University of Texas at Brownsville, US

Kinetics of oxidation of metal nanoparticles acquired practical importance with rapidly developing nanoenergetic systems and materials. Nanoenergetic thermites include mixtures of Al and metal oxides in nanoscale. Our research focuses on modeling aluminum combustion in [...]

Nanoenergetic composite based on I2O5/Al for biological agent defeat

Hobosyan M., Kazansky A., Martirosyan K.S., University of Texas at Brownsville, US

The risk of bioterrorism events involving the intentional airborne release of contagious agents has led to development of new approaches for bio agent defeat technologies both indoors and outdoors. This report describes nanoenergetic gas generators [...]

Modeling of gas dynamic behaviour of CCSO in nanostructured media

Markov A.A., Filimonov I.A., Martirosyan K.S., University of Texas at Brownsville, US

Recently a novel, simple and energy efficient synthesis of nanoparticles of complex oxides referred to as Carbon Combustion Synthesis of Oxides, (CCSO) was developed. In CCSO the exothermic oxidation of nanoscale carbon generates a thermal [...]

Rapid oxidation and self-heating model of aluminum spherical nanoparticles

Zyskin M., Martirosyan K.S., University of Texas at Brownsville, US

Nanostructured highly-exothermic reactive mixtures, referred to as Nanoenergetic Materials (NM) or Metastable Intermolecular Composites (MIC), may release energy much faster than conventional energetic materials. The size reduction of reactant powders such as aluminum from micro- [...]

Polymer Coated Nickel Ferrite Nanoparticles for High-gradient Magnetic Separation

Alvarez R., Trad T.M., Martirosyan K.S., University of Texas at Brownsville, US

Magnetic separation is a complex physical process in which magnetically susceptible composites is extracted from a liquid mixture using magnetic properties of the substances. Several separation procedures are developed based on magnetic susceptibility, magnetohydrostatic, magnetohydrodynamic [...]
