Time-dependence of boundary tensions of solutions: IV. Kinetics of adsorption at liquid-liquid interfaces

Autor: L. Tordai, A. F. H. Ward

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 71:572-584

Various mechanisms are considered which might explain the variation of interfacial tensions with time, when fatty acids are adsorbed from hexane on to a hexane water interface. In these solutions there are both single and associated molecules of the

The relationship between the work function of a metal and its energy of activation for oxidation

Autor: N. R. Bharucha, A. F. H. Ward

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 72:735-738

It has been shown that there is a very highly significant correlation coefficient between the work function (Φ) of metals and the activation energy for oxidation (E). The values of Φ-E tend to decrease slightly with increase in the atomic number.

Time-Dependance of boundary tensions of solutions. III. Thermodynamics of the boundary-bulk equilibrium of fatty acids in hexane-water systems

Autor: L. Tordai, A. F. H. Ward

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 71:482-489

The activity of the solute in the adsorbed layer is calculated, and from this is obtained the activity in bulk by means of interfacial tension data at very low concentrations, using the method previously devised by the authors. This allows the invest

Time-dependence of boundary tensions of solutions. II. Experimental determination of the kinetics and equilibrium of adsorption at liquid-liquid interfaces

Autor: L. Tordai, A. F. H. Ward

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 71:396-408

Boundary tensions have been measured by the method of pendent drops for the interfaces between water and solutions of long-chain fatty acids in hexane over a wide range of concentrations. At low concentrations the interfacial tensions were independen

A Molecular Neuroanatomical Study of the Developing Human Neocortex from 8 to 17 Postconceptional Weeks Revealing the Early Differentiation of the Subplate and Subventricular Zone

Autor: Li Sun, Gavin J. Clowry, Jennifer A. Moss, Susan Lindsay, Nadhim Bayatti, Joseph F. H. Ward, Philip Ambrose

Publikováno v: Cerebral Cortex (New York, NY)

We have employed immunohistochemistry for multiple markers to investigate the structure and possible function of the different compartments of human cerebral wall from the formation of cortical plate at 8 postconceptional weeks (PCW) to the arrival o

A micro‐Raman cell for studying aqueous solutions at high temperatures and pressures

Autor: F. H. Ward, Donald A. Palmer, George M. Begun

Publikováno v: Review of Scientific Instruments. 64:1994-1998

The wetted surfaces of the high‐temperature, high‐pressure Raman cell (400 °C and 1 kbar) were constructed of inert materials (i.e., sapphire or quartz and platinum with gold seals) and designed to allow spectroscopic measurements to be made wit

Description of a polarized source of He i radiation for surface studies

Autor: W. B. Dress, G.L. Nyberg, Thomas A. Carlson, P. A. Agron, F. H. Ward

Publikováno v: Review of Scientific Instruments. 49:736-740

A polarized radiation source has been designed and built for use in angular-resolved photoelectron spectroscopy on surfaces of single crystals under ultrahigh vacuum. The light from a discharge in helium is polarized by a triple reflection from a ser
