We here introduce octahedral silicon serving as a structural center for the design of hydrolytically stable bioactive complexes as demonstrated with the generation of silicon-based high affinity DNA binders. This proof-of-principle study suggests that octahedral silicon complexes are falsely neglected, promising structural templates for widespread applications in chemical biology and medicinal ...

The geometry of a 3D octahedral parallel robot manipulator system is specified in terms of two rigid octahedral structures (the fixed and moving platforms) and six actuation legs. The symmetry of the system is exploited to determine the behaviour of (a new version of) the quality index for various motions. The main results are presented graphically.

A novel complex of cadmium (II) picrate (pic) with V-shaped ligand bis(N-allylbenzimidazol-2-ylmethyl)benzylamine (babb), with composition [Cd(babb)(2)](pic)(2), was synthesized and characterized by elemental analyses and electrical conductivity, IR, and UV/visible spectra. The crystal structure of the complex has been determined by the single-crystal X-ray diffraction. In the complex, the coor...

A new Cu(II) complex of CuL(ClO4)2 (here, L = N,N,N 0,N 0-tetrakis[(2-benzimidazolyl)methyl]-1,3-diaminopropane) has been synthesized and characterized by elemental analyses, UV–Vis, FT-IR, cyclic voltammogram and X-ray single crystal diffraction. The Cu(II) environmental in complex is distorted octahedral. p–p stacking interactions stabilize the crystal packing together with the hydrogenbondin...

We report Pt-Pd nanoparticles synthesized by means of a polyol process with glycerol as a reducing agent. The Pt-Pd nanoparticles exhibit dominantly exposed {111} facets in octahedral shape with complete alloy formation between Pt and Pd. Furthermore, the octahedral Pt-Pd alloy catalysts show improved catalytic activity and stability in methanol electrooxidation.

The Octahedral Tucker problem considers an n-dimensional hypergrid of side length two, centered at the origin, triangulated by connecting the origin to all outside vertices (applied recursively on each of the lower dimensional hypergrids passing through their origins at the corresponding reduced dimensions). Each vertex is assigned a color in ±i : i = 1, 2, ..., n computed using a polynomial si...
