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...
A new triaryl molecule based on a benzene–benzothiadiazole–benzene core has been applied in WOLED device.
Guar gum based hydrogels have evoked great attention in research as well industry for exploring miscellaneous applications the field of water purification, medicine, agriculture, explosives, cosmetics, textile, paper, and food to name a few. In this article, latest modifications developing guar composite materials purification application are extensively reviewed. Regenerative nature makes it better choice treating wastewater other value-added applications. Moreover, nonionic an acceptable...
A novel polyimide (PI) and imide compound emitting prominent reddish-orange fluorescence under excitation by UV light were prepared based on 3-hydroxypyromellitic dianhydride (PHDA), their properties examined. The steady-state spectrum of a PI film displayed an emission band at 590 nm with very large Stokes shift (ν = 10 448 cm–1) via the excited-state intramolecular proton transfer (ESIPT), while time-resolved showed rapid decay enol form around 400 within 15 ps. Transient absorption...

An in-depth analysis of the electro-optical and light-emissive properties was carried out with a new fused heteroacene, bis[(1,2)(5,6)]indoloanthracene. The compound synthesized in straightforward bidirectional manner from 1,4-dibromo-2,5-diodobenzene utilizing reaction cascade isomerization cyclization sequences. Bis[(1,2)(5,6)]indoloanthracene exhibits bright luminescence high quantum yield solution as well solid state. By using this novel semiconductor active layer, an efficient organic...
In the current work, a new antibacterial bandage was proposed where diamond-like carbon with silver nanoparticle (DLC:Ag)-coated synthetic silk tissue used as building block. The DLC:Ag structure, dimensions of nanoparticles, concentration and ion release were studied systematically employing scanning electron microscopy, energy dispersive X-ray spectroscopy atomic absorption spectroscopy, respectively. Antimicrobial properties investigated using microbiological tests (disk diffusion method...
Plasmonic metal nanoparticles arranged in periodic arrays can generate surface lattice plasmon resonances (SLRs) with high Q-factors. These collective are interesting because the associated electromagnetic field is delocalized throughout plane of array, enabling applications such as biosensing and nanolasing. In most cases nanostructures created via top-down nanofabrication processes. Here we describe a capillary-force-assisted particle assembly method (CAPA) to assemble monodisperse...
Electron microscopy, while reliable, is an expensive, slow, and inefficient technique for thorough size distribution characterization of both mono- polydisperse colloidal nanoparticles. If rapid in-situ colloid samples to be achieved, a different approach, based on fast, widely accessible, inexpensive optical measurements such as UV-Vis spectroscopy in combination with spectra interpretation related Mie scattering theory, needed. In this article, we present tandem deep neural network (DNN)...

Noble metal nanoparticles patterned in ordered arrays can interact and generate hybrid plasmonic–photonic resonances called surface lattice (SLRs). Dispersion curves help explain how the Bragg coupling conditions radiation patterns create dipolar quadrupolar SLRs, but they assume that are static structures, which is inaccurate at ultrafast time scales. In this article, we examine local plasmon (LSPRs) supported by cubic Ag nanocrystals modulated photophysical processes optomechanical modes....
Abstract BACKGROUND The increasing global energy crisis and environmental pollution necessitate the development of clean sustainable sources. Photoelectrochemical (PEC) water splitting is a promising approach for hydrogen production, utilizing semiconductor materials to convert solar into chemical energy. However, single semiconductors suffer from high electron–hole recombination, limiting their efficiency. To address this, bifunctional Z‐scheme heterojunction was constructed using bismuth...
