Frictional Electrification

Frictional Electrification on Polymeric Flat Surfaces

The electrostatic charge on nylon, polypropylene (PP), and polytetrafluoroethylene (PTFE) after rubbing against stainless steel and against each other was examined using a newly developed rubbing device with automated features. It is observed that the charge generated on PTFE and PP increases as the contact force increases, while the charge generated on nylon is not affected by the contact forc...

Frictional Coordination

The notion that business cycles are driven by demand shocks is subtle. I first review some of the conceptual and empirical challenges faced when trying to accommodate this notion in micro-founded, general-equilibrium models. I next review my own research, which sheds new light on the observed business cycles by accommodating frictional coordination in the form of higher-order uncertainty. This ...
