The goal of this work is to research the effect different Au-Ag ratios on homogeneity bimetal alloys. Thin films silver (Ag)-gold (Au) alloy were produced using Vaksis Thermal Evaporator system and quartz crystal microbalance detector at gold additive ratios. Micro beam X-Ray fluorescence spectrometer was used calculate bimetallic Ag-Au thin production with concentration values. It seen that ca...

In this theoretical work, we present a spectroscopic analysis of the cis/trans-isomers of a molecular switch, penta-2,4-dienoic acid, attached to gold clusters of different size (1, 2 and 20 gold atoms). We have simulated 4 different spectroscopic techniques: Infrared spectroscopy, normal Raman scattering, absorption spectra and resonance Raman scattering. We discuss how the position and the co...

Indenes and related polycyclic structures have been efficiently synthesized by gold(I)-catalyzed cycloisomerizations of appropriate ortho-(alkynyl)styrenes. Disubstitution at the terminal position of the olefin was demonstrated to be essential to obtain products originating from a formal 5-endo-dig cyclization. Interestingly, a complete switch in the selectivity of the cyclization of o-(alkynyl...

The paper explores the modelling and simulation of a Radio Frequency Micro Electro-Mechanical Systems (RF MEMS) switch with the use of a novel seesaw design providing Double-Pole Double-Throw (DPDT) functionality. This optimises the capabilities of the seesaw design structure for use in mobile communications systems and devices. After researching other available seesaw designs, it was realised ...

With the continuous miniaturization, electrical, high-speed and intelligent of railway signal equipment, the control switch module must have higher safety, reliability and anti-interference ability. Under this background, this paper studied the railway signal distributed computer control switch module. First of all, this paper introduced the main supporting technology of distributed interlockin...

The increasing interest in the use of gold salts as chemotherapeutic agents in the treatment of certain diseases (Hartfall, et al., 1937) has made apparent the necessity of an accurate, specific, and sensitive method for the determination of gold in various biological materials. Moreover, the lack of information regarding the metabolism and pharmacology of this element further emphasizes this n...
