Graphene-induced abnormal grain growth of Cu with a grain size of more than 1 mm(2) was observed on Cu-Ag alloy foil, and this phenomenon occurred only with graphene synthesis and only on the Cu-Ag alloy among various types of Cu foils.

Взаємодію по перерізах Cu(Ag)8Ge(Sn)S6 – Cu(Ag)7PS6 у системах Cu2S GeS2 P2S5 та Ag2S Ge(Sn)S2 досліджено методами РФА, РСА, МСА ДТА. Переріз Cu8GeS6 Cu7PS6 при 300 К є квазібінарним і характеризується значними твердими розчинами: до 30 мол. % включно на основі HT-модифікації від ∼9 32 ВТМ обох сполук. Розчинність НТМ сягає не більше 5 %. Однак в повному досліджуваному температурному інтервалі ...

Cu-Ag thin films with various atomic ratios were prepared using a co-sputtering technique, followed by rapid thermal annealing at various temperatures. The films' structural, mechanical, and electrical properties were then characterized using X-ray diffractometry (XRD), atomic force microscopy (AFM), FESEM, nano-indentation, and TEM as functions of compositions and annealing conditions. In the ...

The complexes of Cu(i) and Ag(i) with 1,3,5-triaza-7-phosphadamantane (PTA) are currently studied for their potential clinical use as anticancer agents, given the cytotoxicity they exhibited in vitro towards a panel of several human tumor cell lines. These metallodrugs are prepared in the form of [M(PTA)4]+ (M = Cu+, Ag+) compounds and dissolved in physiological solution for their administratio...

A tubular array of TiO2 nanotubes on Ti matrix was used as a support for Ag or Cu sputter-deposited layers intended for surface-enhanced Raman scattering (SERS) investigations. Composite samples of Ag/TiO2-nanotube/Ti and Cu/TiO2nanotube/Ti were studied with the aid of scanning electron microscopy (SEM) and Auger electron spectroscopy (AES and SAM) to reveal their characteristic morphological a...

Vermiculite (Ver) enriched with silver and copper was used as nanofiller to the polyethylene (PE) matrix. Specifically, the low density polyethylene (LDPE) was chosen as a matrix. The samples Ver-Ag,Cu were prepared by shaking of Ver with the aqueous solutions of silver and copper nitrate. The mixtures of the Ver nanofillers and PE were homogenized by melt compounding technique and further thin...

solid solutions of ag-cu were prepared via ball milling process, for about 5-30 h. the cu-20at%ag and cu-3.64at%ag composition were investigated by x-ray diffraction technique. it was realized that the solid solubility level could be increased by increasing the initial solute content in the mixture. in addition, shifts in peak positions of silver and copper were observed with milling time. the ...

A series of mixed crystals composed of Cu(2)ZnSnS(4), Ag(2)ZnSnS(4) and ZnS was prepared by co-precipitation of the corresponding metal ions in aqueous sodium sulfide followed by annealing in a sulfur atmosphere. Ideal solid solutions of Cu(2)ZnSnS(4) and Ag(2)ZnSnS(4) with a kesterite structure ((Cu(x)Ag(1-x))(2)ZnSnS(4) (0 ≤x≤ 1)) were successfully obtained by this procedure, as confirmed by ...
