bimetallic powders -- gold-palladium -- redox potential
Аннотация: The redox potential of fine-dispersed and compact bimetallic powders of the palladium-gold system in hydrochloric acid solutions of H2PdCl4 at a temperature of 60A degrees C was studied. It was found that the redox potential increases with gold enrichment of the solid solution in accordance with the Nernst equation. The effect of gold-palladium particle size on this redox potential is shown. The morphology, sizes, and composition of bimetallic particles are determined via transmission electron microscopy and X-ray diffraction analysis.

carbon nanomaterials -- platinum metal nanoparticles -- in situ one-step method
Аннотация: Carbon nanomaterials (fullerite, detonation nanodiamonds, Taunit, fullerenol, fullerene-containing black) were decorated with platinum group metal nanoparticles in situ in one step by low-temperature combustion (~250–270°С) of a powdered mixture of platinum metal acetylacetonate [Pt-M(асас)n, Pt-М = Pt(II), Pd(II), Rh(III), Ir(III), acac = CH3COCHCOCH3, n is the oxidation state of Pt-М] with carbon nanomaterials in air. As shown by thermal analysis, the process is based on thermal oxidative degradation of the organometallic complex, catalyzed by carbon nanomaterials, with oxidation (combustion) of the organic moiety and release of the metal into the condensed phase. The thermal process in an open system occurs in the glowing mode (210–250°С); the size of the nanoparticles formed is 7–30 nm. Under the conditions restricting the air access to the reaction mixture and free outflow of gaseous products formed by oxidation of acac ligands, the nanoparticle size decreases to 3–10 nm. The particle size depends on the metal amount in the initial powder mixture and on the support morphology.

Кл.слова (ненормированные):
transparent electromagnetic interference (EMI) shielding films -- cracked template -- electroplating -- photocurable resin -- embedded mesh -- durability
Аннотация: Embedded copper mesh coatings with low sheet resistance and high transparency were formed using a low-cost Cu seed mesh obtained with a magnetron sputtering on a cracked template, and subsequent operations electroplating and embedding in a photocurable resin layer. The influence of the mesh size on the optoelectric characteristics and the electromagnetic shielding efficiency in a wide frequency range is considered. In optimizing the coating properties, a shielding efficiency of 49.38 dB at a frequency of 1 GHz, with integral optical transparency in the visible range of 84.3%, was obtained. Embedded Cu meshes have been shown to be highly bending stable and have excellent adhesion strength. The combination of properties and economic costs for the formation of coatings indicates their high prospects for practical use in shielding transparent objects, such as windows and computer monitors.
