Unique Approaches to Interfacial Nanoscience
Other applications of the nanofabrication techniques are also explored. The nanopatterning of mica with a focused ion beam (FIB), shown for the first time here, has led to the formation of a wide variety of nanorod structures embedded in and supported by a number of different surfaces. The …

Hydrogen embrittlement: an interfacial phenomenon
Hydrogen transport during a test and hydrogen segregation to twins, second phase particles and precipitation products prior to testing are shown to adversely effect the mechanical properties of metals. Hydrogen embrittlement processes in austenitic stainless steel, mild steel and aluminum occurred …

Mathematical problems arising in interfacial electrohydrodynamics
… and complex nonlinear dynamics including chaotic interfacial oscillations. It is established that a sufficiently high electric field will drive the system to chaotic oscillations, even when the Reynolds number is smaller than the critical value below which the non-electrified problem is linearly …

Designing interfacial structures for selective electrocatalysis
Selectivity of electrocatalysis in fuel cells stresses on the tolerance of electrode catalysts to cross-over species. A typical polymer electrolyte membrane fuel cell (PEMFC) employs a Nafion-based membrane to separate the Pt-based cathode and anode. Nevertheless, the intrinsic porosity of Nafion …
