We present a systematic experimental study on the optical properties of plasmonic crystals (PlC) with hexagonal symmetry. We compare the dispersion and avoided crossings of surface plasmon modes around the Γ-point of Au-metal hole arrays with a hexagonal, honeycomb and kagome lattice. Symmetry arguments and group theory are used to label the six modes and understand their radiative and dispersi...

in this study, porcelain bond strength to three different alloys of gold-base, pd-ag and base-metal were compared and the effect of repeated porcelain sintering on bond strength was evaluated. the obtained results showed best bond strength of porcelain with gold-base alloy. pd-ag and base-metal alloys showed less strength respectively. during repeated sintering of porcelain, bond strength has n...

We present a detailed study of the effects of interface spin-orbit coupling on the critical field behavior of ultrathin superconducting Be/Au bilayers. Parallel field measurements were made in bilayers with Be thicknesses in the range of d=2-30 nm and Au coverages of 0.5 nm. Though the Au had little effect on the superconducting gap, it produced profound changes in the spin states of the system...

The title compound, [Au(C(9)H(9)ClNOS)(C(18)H(15)P)], features a linear S,P-donor set with a small deviation from the ideal linear geometry due to the proximity of the meth-oxy O atom to Au [Au⋯O = 2.986 (4) Å].

The Au atom in the title compound, [Au(C(10)H(12)NOS)(C(18)H(33)P)], is coordinated within an S,P-donor set that defines a slightly distorted linear geometry [S-Au-P = 174.54 (2)°], with the distortion due in part to a close intra-molecular Au⋯O contact [3.1702 (16) Å]. In the crystal structure, mol-ecules are arranged into supra-molecular chains along the b axis mediated by C-H⋯O inter-actions.

In the title compound, [Au(C(8)H(7)ClNOS)(C(18)H(15)P)], the Au(I) atom has a near-linear geometry, defined by an S,P-donor set [S-Au-P = 175.09 (5)°]. The proximity of the meth-oxy O atom to Au may be responsible for the deviation from linearity [Au⋯O = 2.959 (4) Å].
