We present a configurational-biased lattice Monte Carlo scheme for simulating nonideal dendrimers that satisfies detailed balance. This corrects an important shortcoming in a previous lattice Monte Carlo scheme by Mansfield and Klushin: in a previous...

A lattice Monte Carlo scheme for simulating dendrimers that is widely referenced in the literature is that of Mansfield and Klushin (Macromolecules 1993, 26, 4262). However, we show that this scheme does not obey a detailed balance and propose a modi... Read More about Monte Carlo simulation scheme for dendrimers satisfying detailed balance.

Linear melt rheology and small-angle X-ray scattering of AB diblocks vs A2B2 four arm star block copolymers (2000)
Journal Article

The frequency dependent viscoelastic properties and lamellar spacing of three symmetric styrene-isoprene (PS-PI) diblock copolymers are compared to those of their hetero-four-arm star counterparts. The PS and PI arm molecular weights of the three lin... Read More about Linear melt rheology and small-angle X-ray scattering of AB diblocks vs A2B2 four arm star block copolymers.

Interaction between colloidal particles on an oil-water interface in dilute and dense phases
Presentation / Conference Contribution
Parolini, L., Law, A. D., Maestro, A., Buzza, D. M. A., & Cicuta, P. Interaction between colloidal particles on an oil-water interface in dilute and dense phases

The interaction between micron-sized charged colloidal particles at polar/non-polar liquid
interfaces remains surprisingly poorly understood for a relatively simple physical chemistry
system. By measuring the pair correlation function g(r) for differ... Read More about Interaction between colloidal particles on an oil-water interface in dilute and dense phases.

Size exclusion chromatography and rheology of AB/AB2 hyperbranched polymers
Presentation / Conference Contribution
Kunamaneni, S., Buzza, D. M. A., Parker, D., & Feast, W. J. Size exclusion chromatography and rheology of AB/AB2 hyperbranched polymers

We report size exclusion chromatography (SEC) and linear shear rheology results for a series of AB/AB2 hyperbranched polyesters. For these samples, the weight average molecular weight Mw was systematically varied from 3000 to 250000 but the spacer le...
