On the Bindings in the Mixture PtSnM [PDF]

open access: yes, 1986
As an example from a more extensive investigation, the binding analysis of the mixture PtSnM (M = undetermined mole number) is described. A phase becomes stable when a lattice-like correlation of the valence electrons (with cell b) and a lattice-like ...

Biopharmaceutical characterisation of ciprofloxacin-metallic ion interactions: Comparative study into the effect of aluminium, calcium, zinc and iron on drug solubility and dissolution [PDF]

open access: yes, 2014
Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in ...

Crystal structure, spectroscopic investigations, and physical properties of the ternary intermetallic REPt2Al3 (RE = Y, Dy–Tm) and RE2Pt3Al4 representatives (RE = Tm, Lu) [PDF]

open access: yes, 2018
The REPt2Al3 compounds of the late rare-earth metals (RE = Y, Dy–Tm) were found to crystallize isostructural. Single-crystal X-ray investigations of YPt2Al3 revealed an orthorhombic unit cell (a = 1080.73(6), b = 1871.96(9), c = 413.04(2) pm, wR2 = 0 ...

Systematic Investigations of the Solid Solution Zr(V1-xAlx)2 Adopting the Laves Phase Structures [PDF]

open access: yes
Laves phases are an interesting field of research when it comes to structural chemistry and physical properties. Investigations of the ternary system Zr–V Al showed, in contrast to the system Hf–V Al, that no superstructures can be observed within the
