Square macrocyclic complexes have attracted significant attention due to their unique structure and molecular recognition property. Here we report a square macrocyclic complex using an electron-acceptor ligand N,N’-di(4-pyridyl)-1,4,5,8-naphthalenediimide (dpndi), [Pt(en)(dpndi)]4(SO4)4·20H2O...

Orientation Distribution Functions

The calculation of orientation distribution functions (ODF) from incomplete pole figures can be carried out by an iterative procedure taking into account the positivity condition for all pole figures. This method strongly reduces instabilities which may occasionally occur in other methods.

Generalized Spherical Harmonics

An explicit representation is suggested for orthogonal generalized spherical harmonics with cubic-crystal and triclinic-sample symmetries. The representation employs sums and differences of orthogonal generalized spherical harmonics with cubic-crystal symmetry, previously described by Bunge for orthorhombic (or higher) sample symmetry, and is illustrated, for T∴iμυ, i = 4, 9, μ = 1, υ = 1 to 5. This representation facilitates crystallite orientation distribution (COD) analysis (aka ODF analysis) for these symmetries, using the Bunge formalism.

Two novel CO2-stable dual-phase oxygen-transporting membranes were successfully developed by Al-doping of the perovskite phase Nd0.6Sr0.4FeO3. Enhanced oxygen fluxes were achieved, due to increased oxygen non-stoichiometry and the modified cubic crystal symmetry of the perovskite.

Analytic Determination

The problem of the analytic determination of microstresses in textured polycrystals with cubic symmetry under general static loading has been solved. The solution is based on the expansion of macroscopic and microscopic stress fields into hydrostatic and deviatoric portions. This essentially simplifies the description of microstresses in polycrystals.
