Copper sulfide layers were formed on polyamide PA 6 surface using the sorption‐diffusion method. Polymer samples immersed for 4 and 5 h in 0.15 mol ⋅ dm −3 K 2 S O solutions acidified with HCl (0.1 ) at 20 ∘ C. After washing drying, treated Cu(I) salt solution. The studied by UV/VIS, X‐ray diffraction (XRD) photoelectron spectroscopy (XPS) methods. All methods confirmed that of film a layer copper was formed. are indirect band‐gap semiconductors. values E bg 1.25 1.3 eV sulfured...
In the present research diamond-like carbon (DLC) films containing 4-29 at.% of silicon were deposited by reactive magnetron sputtering target. Study X-ray photoelectron spectroscopy revealed presence Si-C bonds in films. Nevertheless, a significant amount Si-O-C and Si-Ox was too. The shape Raman scattering spectra all studied (DLC:Si) typical for carbon. However, some peculiarities related to doping found. Studies on dependence DLC:Si optical transmittance Si atomic concentration have...
In this recent decade, great interest has risen to develop metal-free and cheap, biomass-derived electrocatalysts for oxygen reduction reaction (ORR). Herein, we report a facile strategy synthesize an electrochemically active nanocarbon material from the renewable biological resource, wood biomass. The ORR activity of catalyst was investigated in 0.1 M KOH solution by employing rotating disc electrode method. Scanning electron microscopy, transmission X-ray photoelectron spectroscopy, Raman...
A facile and feasible protocol for synthesis of functionalized reduced graphene oxide decorated with gold nanoparticles (AuNP/rGO) in mild reaction conditions has been successfully developed. Starting from graphite, the following routes were developed: (1) preparation graphite oxide; (2) (GO) a compatible polymer; (3) (final compound). The surface morphology as-prepared AuNP/rGO was investigated using scanning electron microscopy (SEM) specific area determined BET method, while structural...
We present Raman studies of graphene films grown on copper foil by atmospheric pressure CVD with n-decane as a precursor, mixture nitrogen and hydrogen the carrier gas, under different flow rates. A novel approach for processing spectroscopy data was employed. It found that in particular cases, various parameters spectra can be assigned to fractions thicknesses. In particular, such quantities full width at half maximum 2D peak position band were successfully applied elaborated approach. Both...
Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is the most successful transparent conductive polymer widely used in functional organic devices. However, its potential fabrication of highly electrodes still has not been fully explored. This paper an attempt to fill existing gap knowledge on possible post-treatments dimethyl sulfoxide (DMSO)-doped PEDOT:PSS thin films. In present study, surface morphology, optical and electrical properties untreated sulfuric acid treated...
In this paper, silver-doped zinc oxide nanoparticles were synthesized by using a solution combustion technique, in which nitrate is used as an oxidizer and tartaric acid fuel. The phase composition, morphology structural properties of the as-synthesized established powdered X-ray diffraction, field emission scanning electron microscopy coupled with energy-dispersive spectroscopy, photoelectron spectroscopy studies. Due to well-defined morphologies crystallinity, pure nanostructures can be...

Waveplates, used to modify polarization state of light, are integral part high‐power lasers. Classical approach waveplate manufacturing is based on combination birefringent crystalline materials and deposition nonpolarizing antireflection (AR) coatings. Their limitation withstand maximal peak power determined by laser‐induced damage (LID) phenomena, mainly low band‐gap in AR In this study, a novel multi‐layer high coatings was proposed investigated overcome limitation. Three eligible...
