Brushes of Statistically Branched Polymers
Daniel O. LeSher, Grant L Metheny, Galen T. Pickett
We determine the distribution of free ends and the monomer insertion potential in the strongly-stretched limit for regularly and statistically branched polymer brushes. We find tha…
A Pedagogical Model of Static Friction
Galen T. Pickett
While dry Coulombic friction is an elementary topic in any standard introductory course in mechanics, the critical distinction between the kinetic and static friction forces is som…
Confetti Ordering by Polymer Brushes
Galen T. Pickett
I consider the ordering of dilute platelet additives when incorporated into an end-grafted polymer brush. The competition between wetting interactions and the anisotropic stress en…
Entropic Trapping of Particles at Polymer Surfaces and Interfaces
Galen T. Pickett
I consider the possibility that Gaussian random walk statistics are sufficient to trap nanoscopic additives at either a polymer interface or surface. When an additive particle goes…
Volume Integral of the Pressure Gradient and Archimedes' Principle
Galen T. Pickett
The theorems of vector analysis (divergence theorem, etc.) are typically first applied in the undergraduate physics curriculum in the context of the electromagnetic field and the d…
Instabilities of micro-phase separated Coulombic systems in constant electric fields
Francisco J. Solis, Galen T. Pickett
Mixtures of near-symmetric oppositely charged components with strong attractive short range interactions exhibit ordered lamellar phases at low temperatures. In the strong segregat…
