The present invention is aimed to provide an electroless gold plating solution which requires less amount of a reducing agent, retains a sufficient deposition rate for a practical use, and has an excellent stability as a plating solution; and a method for carrying out an electroless gold plating...
Gold: descriptionYour user agent does not support the HTML5 Audio element. Most metals are metallic grey or silvery white whereas gold is characteristically a metallic yellow colour, in other words gold-coloured. Caesium is also gold coloured. The gold colour seems related to relativistic effects ...
Reactions of gold as the element with air, water, halogens, acids, and bases where known. View reactions of gold... Gold: compound properties Bond strengths; lattice energies of gold halides, hydrides, oxides (where known); and reduction potentials where known. ...
It uses the H+ ions for the growth and reproduction at the beginning of the process, as shown in equation (3), where M represents the polymetallic element [6]. The bioleaching process of the gold ore involves the oxidation of sulfur and a sulfide mineral which is represented by equations ...
Multimodal nanoparticles, utilizing quantum dots (QDs), mesoporous silica nanoparticles (MSNs), and gold nanoparticles (Au NPs), offer substantial potential as a smart and targeted drug delivery system for simultaneous cancer therapy and imaging. This me
These were (1) an early deep-seated metamorphic fluid for stage-1 mineralization and, (2) a mixture of magmatic and formational fluid for stage-2 mineralization. Tourmaline major and trace element compositions from the stage-1 mineralization assemblage suggest a low salinity reduced trace element ...
{1H} NMR spectra. In compound3,Jppwas 0.12 ppm while in compound6it was 0.41 ppm. The presence or absence of the resonance structure of the P-C-C-P bridge influencesJppcoupling. Specifically,Jppis smaller in the structure having the π electron bridge (complex3), andJppis relatively ...
PURPOSE:To obtain a gold alloy improved in color tone and brittleness inherent in AuAl2 and excellent in ornamental property by mixing a powder of a specific metal or alloy with a powder of an intermetallic compound AuAl2 having a purple color tone, compacting the above powder mixture, and ...
X-ray mask fabrication based on BCN compound membrane and gold containing polymeric carbon ( Au-C ) absorber by totally dry processes is proposed. The Au-C films were depo-sited by plasma polymerization of propylene or styrene monomers and co-evaporation of gold. These films have 2 to 5 tim...
Targeted and effective therapy of diseases demands utilization of rapid methods of identification of the given markers. Surface enhanced Raman spectroscopy (SERS) in conjunction with streptavidin–biotin complex is a promising alternative to culture or P
