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].

Multivalent nanostructures are becoming an increasingly important player in the self-assembly of supramolecular lattices. Understanding the role that shape plays in the coordination of the assemblies is crucial for the functional response of the material. We develop a simple design rule for the assembly of multivalent Au triangular nanoprisms into 1-D ordered arrays based on both the length of ...

a simple, precise, inexpensive and sensitive voltammetric method has been developed for the determination of gemifloxacin mesylate (gem) in the presence of tween 80 in the bulk, farmaceutical dosage forms and human urine at gold nanoparticles modified carbon paste electrode (gncpe). the electrochemical behavior of gem has been investigated by using cyclic voltammetry (cv) and differential pulse...

in this research, gold nanoparticles were synthesized and functionalized by the antibody of aflatoxins. the quenching of the fluorescence of excitation emission matrices (eem) of two type of aflatoxins (b1, g1), provoked by the gold nanoparticles, was studied by principal component analysis (pca) and multivariate curve resolution with alternating least squares (mcr-als). these aflatoxins show q...

due to the binding of the –coo- group with the mercury (ii), gold nanoparticlesfunctionalized with glutathione can self-assemble to form a supermolecular network in the hac-naac buffer solution. the aggregation of functionalized gold nanoparticles and mercury (ii)caused the shift of maximum absorption peak of the uv-vis spectrum from 520 nm to 609 nm.based on this principle, a simple spectropho...
