Parsons’ function

The Parsons function is defined through = 7 + it is the thermodynamic potential that has the charge density a as the basic variable instead of the potential (j>. Show that the surface excess of a... 

This is known as the Parsons function and is often used in the analysis of interfacial thermodynamic data. Taking the total derivative of one obtains... 

It is often more convenient to analyze the data at constant electrode charge density c rather than constant potential E. Introducing the Parsons function = y -I- a E, one may write... 

Then, using Parsons function, = Q + y, to change the electrical independent variable, the following expression is obtained ...

The notion of pzc is absent in early textbooks. A table with pzc values for about 10 metals (but for only 5 are reliable values claimed) was given by Parsons in 1954 in the first volume of this series.4 After a more complete attempt by Frumkin in 196520 to compare work function, extensive work on pzc was reported by Perkins and Andersen9 in this series and by Frumkin etal.8 in another series. Compilations of pzc values were also made by Campanella, Trasatti, Frumkin et al., and Frumkin and Petrii14 up to 1979. A book by Frumkin10 devoted entirely to the potential of zero charge was published posthumously in 1979.

D-cycloserine and (-l-R)-HA-966 are partial agonists at the glycincB site with different levels of intrinsic activity (Karcz-Kubicha et al. 1997). Although these systemically active partial agonists do not induce receptor desensitization they have favourable therapeutic profiles in some in vivo models (Lanthorn 1994 see Danysz and Parsons 1998). This may, in part, be due to their own intrinsic activity as agonists at the glycines site, which would serve to preserve a certain level of NMDA receptor function even at very high concentrations (Danysz and Parsons 1998).

MRZ-2/576 has been demonstrated to cross the blood -brain barrier rapidly and to function centrally as a glycineB antagonist after systemic administration of doses within the relevant antinociceptive dose range. However, the compound is only short-acting within the CNS because of a relatively short half-life within this compartment (Parsons et al., 1997). The compound has antinociceptive properties and shows exceptionally good efficacy in a visceral pain model (McClean et al., 1998 Olivar et al., 1999).

Work Function (WF) plays a key role in the physics and chemistry of materials. Phenomena such as the semiconductor field effect, photo- and thermionic electron emission (Allen and Gobelli, 1962), catalysis (Vayenas et al 1996), and the like are dominated by the WF. This fundamental property of electronic materials is defined as the minimum work required to extract an electron from the Fermi level Ep of a conducting phase, through the surface and place it in vacuum just outside the reach of the electrostatic forces of that phase (Trasatti and Parsons, 1986). The reference level for this transfer is thus called the vacuum reference level. Because even a clean surface is a physical discontinuity, a surface dipole t] with its associated electric field always appears at the surface of the condensed phase. Thus, the work of extracting the electron can be conceptually divided between the work required to...
