Abstract The aim of our work was the synthesis ZnO nano- and microparticles to study effect shapes sizes on cytotoxicity towards normal cancer cells antibacterial activity toward two kinds bacteria. We fabricated through facile chemical physical routes. crystal structure, morphology, textural properties, photoluminescent properties were characterized by powder X-ray diffraction, electron microscopies, nitrogen adsorption/desorption measurements, photoluminescence spectroscopy. obtained...
MXenes are a novel family of 2D materials, which extensively investigated for common use in energy storage systems, nanoelectronics, and electromagnetic shielding. Although their unique physicochemical properties render wide applicability, cytotoxic response safety still remain concern. From this perspective, it is imperative to perform an vitro investigation the influence different forms precursors on human cell lines. Therefore, we prepared selection multi-, few-, single-layered Ti3C2Tx,...
This study discusses the value of polymer electrospun materials in three-dimensional (3D) scaffolds and antibacterial wound dressings for potential dental applications.
The study discusses the value of electrospun cilostazol-loaded (CIL) polymer structures for potential vascular implant applications. Biodegradable polycaprolactone (PCL) fibers were produced by electrospinning on a rotating drum collector. Three different concentrations CIL: 6.25%, 12.50% and 18.75% based amount polymer, incorporated into fibers. characterized their size, shape orientation. Materials characterization was carried out Fourier Transformed Infrared spectroscopy (FTIR), Raman...
The high specific surface area of multilayered two-dimensional carbides called MXenes, is a critical feature for their use in energy storage systems, especially supercapacitors. Therefore, the possibility controlling this parameter highly desired. This work presents results influence oxygen concentration during Ti3AlC2 ternary carbide—MAX phase preparation on α-Al2O3 particles content, and thus porosity Ti3C2Tx MXenes. In research, three different samples were prepared, based TiC-Ti2AlC...
This article describes how crystalline or fibrous nanocellulose influences the mechanical properties of paper substrate. In this context, we used commercially available cellulose nanocrystals, mechanically prepared nanofibers dispersed in water ethanol, and carboxy nanofibers. Selective reinforcement treated with samples mentioned above was observed. The change fibre structure assessed using scanning electron microscopy, roentgenography, spectroscopy techniques. addition, effect coating on...
Novel triple-layered trimetallic Au/Pd/Pt nanoparticles (NPs) with a porous Pt shell, showing hedgehog-like structure, were successfully bounded TiO2 and NaTaO3 surfaces, used for photocatalytic purpose. To characterize all as-prepared samples, XRD, TEM, EDX, SEM, ISP-OES, DRS, XPS, photoluminescence (PL) emission spectroscopy applied. It was found that 25 nm core–shell NPs formed, good interaction between the outer shells semiconductor surface obtained. appraise effect of semiconductor's...
This study is devoted to the evaluation of influence phosphate dopants on reactivity Nb2O5-based nanomaterials in combined catalytic activation H2O2 and elimination methylene blue (MB) from an aqueous solution via adsorption chemical degradation. For this purpose, several niobia-based catalysts doped with various amounts were prepared by a facile hydrothermal method subsequent calcination. Phosphate doping was shown strongly enhance ability Nb2O5 activate H2O2, as well adsorb degrade MB. The...
Structural determinations as a function of temperature allowed us to model the polar properties guanidinium iodide, C(NH)2I, in its hexagonal P63mc-symmetric phase. These results have been compared with experimental data pyroelectric measurements. It has shown that crystal lattice polarization, arising from ionic displacements, increases and abruptly vanishes at first-order phase transition high-temperature monoclinic space group P21/m. Thus, this non-typically lowers symmetry when is...
In this study, the structure of nanoconfined ice and its behavior during melting process have been investigated. For purpose, deionized water was inserted into pores ordered carbon structures CMK-3 CMK-8 having different diameters. The first set experiments performed using differential scanning calorimetry (DSC), from which transition temperature confined determined. order to investigate formed inside mesopores, wide-angle X-ray scattering used. measurements were at temperatures 173 K up...
In this study, GNF@ZnO composites (gelatin nanofibers (GNF) with zinc oxide (ZnO) nanoparticles (NPs)) as a novel antibacterial agent were obtained using wet chemistry approach. The physicochemical characterization of ZnO (NPs) and composites, well the evaluation their activity toward Gram-positive (Staphyloccocus aureus Bacillus pumilus) Gram-negative (Escherichia coli Pseudomonas fluorescens) bacteria performed. NPs synthesized facile sol-gel Gelatin by an electrospinning technique. adding...
