Metcalfe The group of Professor Metcalfe has combined kinetic and work function measurements to investigate the electrochemical promotion of CO oxidation on Pt/YSZ and, more recently, had made important modeling advances for the fundamental description of electrochemical promotion at the molecular level.

An objective function measuring the deviation from the parameterized model and the target response, determined, for example, from density functional theory based methods can be defined as [Pg.245]

The technique of photoemission electron spectroscopy (PEEM) is a particularly attractive and important one for spatially resolved work function measurements, as both the Kelvin probe technique and UPS are integral methods with very poor ( mm) spatial resolution. The PEEM technique, pioneered in the area of catalysis by Ertl,72-74 Block75 76 and Imbihl,28 has been used successfully to study catalytic oscillatory phenomena on noble metal surfaces.74,75 [Pg.257]

Note that k(t = 0) = 1. What does this function measure The function Q[q(t) — q follows each trajectory and counts 1 if the trajectory is in the product well and 0 otherwise. [Pg.206]

Correlation functions measure the relationship between two variables, x and y. A common definition is [Pg.380]

This function measures the correlation of the property A (it) to itself at two different times separated by the time interval t, averaged over the whole trajectory. The auto-correlation function is reversible in time [i.e., CaU) = it)], and it is stationary (i.e., (A(it + t)A(t)) [Pg.54]

Distribution functions measure the (average) value of a property as a function of an independent variable. A typical example is the radial distribution function g r) which measmes the probability of finding a particle as a function of distance from a typical [Pg.378]
