Photochemical interaction of polystyrene nanospheres with 193 nm pulsed laser light
Article Abstract:
The photochemical interaction of 193 nm light with polystyrene nanospheres is used to produce particles with a controlled size and morphology. The result shows that irradiated particles have a smaller mean diagram and a number concentration more than an order of magnitude higher than nonirradiated particles and the particles are formed by nucleation of gas-phase species produced by decomposition of nanospheres.

Kinetics of aggregation and gel formation in concentrated polystyrene colloids
Article Abstract:
A model based on PBE in dimensionless form is developed for the aggregation of colloidal dispersion in nonsheared conditions. A demonstration that the measured aggregation kinetics could be accurately described by population balance equations, which is the Smoluchowski aggregation equation, at all solid volume fractions investigated is presented.

Fabrication of a two-dimensional periodic non-close-packed array of polystyrene particles
Article Abstract:
A simple technique for the fabrication of a two-dimensional periodic non-close-packed array of nonspherical particles is reported. The technique exploits the self-assembly of uniformly sized colloidal microspheres on the surface of a Si substrate followed by reactive ion etching (RIE) that converts the spheres into nonspherical particles.
