Mechanism of nanoparticle formation in self-assembled colloidal templates: Population balance model and Monte Carlo simulation

Article Abstract:

The deterministic population balance equation (PBE) model and stochastic Monte Carlo (MC) simulation are used to analyze the mechanism of the formation of a self-assembled colloidal template in water-in-oil. The model predictions have shown that an increase in the external reactant addition rate to microemulsion solution is beneficial under general conditions, increasing the nanoparticle production rate without any undesirable and perceptible change in particle size.

Dispersion and size control of layered double hydroxide nanoparticles in aqueous solutions

Article Abstract:

A simple and effective method is developed to prepare stable homogeneous suspensions containing monodispered MgAl layered double hydroxide (LDH) nanoparticles in a wide range of compositions. The LDH suspension can be used as the cellular drug delivery agent and as the nanofillers in polymer nanocomposites, while the LDH thin films can be used for catalysis, gas separation, sensing, and electrochemical materials.

Gating of enhanced electron-charging thresholds in self-assembled nanoparticle films

Article Abstract:

Conductance of butanedithiol interconnected nanoparticles films is measured with systematically varying thickness, to explore properties of materials with interpolating behavior. Films below certain threshold coverage exhibit thermally assisted conductance and conductance suppression near zero indicative of single-electron-charging barriers.
