TL;DR: In this article, the valency of Mn in Cu-Zn alloys was confirmed by measurements with the isoelectronic Cu-Al and Cu-Ge alloys as matrices for Mn.
Abstract: Previous measurements of the valency of Mn in Cu-- Zn alloys were confirmed by measurements with the isoelectronic Cu-Al and Cu-Ge alloys as matrices for Mn. The valency, having the value 1 in pure copper, decreased slightly with increasing electron to atom ratio attaining the values 0.9 and 0.8 at the limiting composition in the Al and Ge alloys respectively. The apparent size of Mn in these alloys is discussed. (auth)

01 Feb 1987Abstract: If u and v are vertices of the (finite, connected) graph F, let d(u, v) denote the length of the shortest path joining u to v in F. The graph F is said to be distance-transitive if whenever d(u,v) = d(u',v'), there exists an automorphism g of F such that u = u' and if = v'. Distance-transitive graphs of valency 3 and 4 were originally classified [2, 11, 12, 13] by using a computer to generate all "feasible intersection arrays" (cf. [1, Chapter 20]). In both cases a classification has since been given by hand [4, 5]. We continue this latter tradition and prove the following theorem—which was recently proved independently by Ivanov et al. using a computer [10].

TL;DR: In this article, a planar electric double layer with anisotropic-shaped ions having asymmetric valencies was modeled and Monte Carlo simulation results were obtained for 2:1/1:2 valency asymmetry in the electrolyte solution regime at room temperature.
Abstract: Canonical and grand canonical Monte Carlo simulation results are reported for the structure of a planar electric double layer containing anisotropic-shaped ions having asymmetric valencies. The model double layer consists of an electrolyte formed by a mixture of charged dimers and charged hard spheres in a dielectric continuum next to a uniformly charged, non-polarisable, planar hard electrode. A dimer is made of two tangentially touching equi-sized hard spheres one of which is positively charged and the other neutral, while the monomer rigid ion of the same size is negatively charged. Results for the electrode-ion, electrode-neutral sphere singlet distributions, and the mean electrostatic potential are obtained for 2:1/1:2 valency asymmetry in the electrolyte solution regime at room temperature, and at a given electrolyte concentration for a series of electrode surface charge densities. Valency asymmetry coupled with anisotropic ion shape leads to a richer double-layer structure than seen previously with...
