Application of Sugimoto model on particle size prediction of colloidal TiO2 nanoparticles

Mehranpour H., Askari M., Ghamsari M.S., Farzalibeik H., Sharif University of Technology, IR

This can be provided by understanding the nucleation and growth mechanism of nanoparticles. In this paper, the nucleation and the growth of TiO2 nanoparticles were studied with Sugimoto model, in a homogeneous closed system which [...]

A Kinetic Study of the MOCVD of GaN

Moscatelli D., Cavallotti C., Politecnico di Milano, IT

Quantum chemistry investigations have been performed to study the gas phase chemistry active during the MOVPE of GaN when Ga(CH3)3 and NH3, diluted in a H2 carrier gas, are used as precursors. Optimized molecular geometries, [...]

Preparation of Functional LLDPE/LDPE/TiO2 Membranes

Wang X-Y, Wang X., Lee J-H., Wang X-Y, Wang X., Hong C-E, Chonbuk National University, KR

Nano-scaled TiO2 has now been used in polymer industry due to its promising properties in light catalyst and UV light shielding[1-3]. In the present paper, functional LLDPE/LDPE/TiO2 membranes were successfully manufactured. To solve the poor [...]

Self Assembly of Globular Protein Nanoparticles

Shiryayev A., Gunton J.D., Lehigh University, US

A continuum model of the self-assembly of globular protein nanoparticles proposed by Talanquer and Oxtoby (J. Chem. Phys. 109, 223 (1998)) is investigated numerically, with particular emphasis on the region near the metastable fluid-fluid coexistence [...]

Crystallization of Membrane Protein Nanoparticles

Shiryayev A., Holby E.F., Gunton J.D., Lehigh University, US

The self-assembly of membrane proteins from solution into two-dimensional crystals is studied numerically using a continuum model proposed by Talanquer and Oxtoby (J. Chem. Phys. 109, 223 (1998)). Although the mean ¯eld theory presented here [...]

Kinetic and Numerical Approaches to Nucleation and Growth During a First Order Phase Transition

ten Bosch A., Zhukhovitskii D.I., CNRS, FR

Novel nanostructures are created during first order phase transitions. Embryos of the new phase are formed by aggregation of particles which diffuse in the local field. Two model independent approaches to nucleation are described : [...]
