s The purpose of this study was carried out by the embryotoxicity risk assessment of the dental alloys containing indium. We produced Ag-In alloy, Ag-Pd-Au-Cu alloy and gold alloy for porcelain bonding. For the extraction of these alloy components into the ES-D3 cell culture medium, each alloy was reduced to a powder using a diamond point and sterilized after rinsing. In order to facilitate the...

We proposed using metal-insulator-metal (MIM) nanorod arrays for subwavelength imaging to improve the resolution based on the notable ability of field confinement of the MIM nanorods. The field distribution of a single Au-SiO(2)-Au nanorod, coupling between two nanorods and image transfer of shaped dipole sources through nanorod arrays were investigated by using the finite-difference time-domai...

A plane-wave density functional theory is used to predict the work functions of Au/Mg decorated Au(100), Mg(001), and stochiometric AuMg alloy surfaces. We find, that irrespective of the details, all Au/Mg systems containing Mg on the surface reveal the Mg-dominated work functions, i.e., significantly shifted toward the work function of clean Mg(001) surface. The reported analyses suggest, that...

Au-Cu mineralization at Palai-Islica occurs as disseminations in massive silicified volcanic rocks and, more abundantly, in sulphide-bearing quartz veins. The major ore minerals in the deposit are pyrite ± chalcopyrite, sphalerite and galena and there is a great variety of accessory minerals, including Au-Ag alloys and native gold. Pyrite, the most abundant sulphide, is closely associated with ...

(Au-Ag)(144)(SR)(60) alloy nanomolecules were synthesized and characterized by ESI mass spectrometry to atomic precision. The number of Ag atoms can be varied by changing the incoming metal ratio and plateaus at ∼60. UV-vis data demonstrates that the electronic structure of the nanomolecules can be tuned by incorporation of silver atoms. Based on the proposed 3-shell structure of Au(144)(SR)(60...

Using tensile tests, this study investigated differences in the welding strength of casts of cobalt-chromium and gold alloys resulting from changes in the voltage and pulse duration in order to clarify the optimum conditions of laser irradiation for achieving favorable welding strength. Laser irradiation was performed at voltages of 150 V and 170 V with pulse durations of 4, 8, and 12 ms. For c...
