Cellulose nanocrystals (CNCs) were prepared from bleached wood pulp by the acid hydrolysis method. CNCs were characterized by Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Diffraction (XRD). Natural rubber latex was oxidised using potassium permanganate. The oxidation of latex was confirmed using FTIR and U…
Background To date, few data on the safety profile of gadoterate meglumine in pediatric patients are available. Purpose To assess the safety profile of gadoterate meglumine in routine practice, to detect any case of nephrogenic systemic fibrosis (NSF) suspicion and to collect efficacy data. Material and Methods The pe…
It is well known that the physical and electro-optical properties of liquid crystals can be controlled by doping with nanoparticles. In this study, we investigated the electro-optical properties of homogeneous aligned liquid crystal devices doped with various titanate nanoparticles, such as TiSiO₄, BaTiO₃, SrTiO₃ and…
Vibration of an axially loaded viscoelastic nanobeam is analyzed in this study. Viscoelasticity of the nanobeam is modeled as a Kelvin-Voigt material. Equation of motion and boundary conditions for viscoelastic nanobeam are provided with help of Eringen’s Nonlocal Elasticity Theory. Initial conditions are used in solu…
This is the second in a series of papers on conformal tilings. The overriding themes here are local isomorphisms, hierarchical structures, and the conformal “type” problem. Conformal tilings were introduced by the authors in 1997 with a conformally regular pentagonal tiling of the plane. This and even more intricate h…
BACKGROUND: Many spinning patents and technologies have been explored to produce diverse types of nanomaterials for different applications. As a novel method, the blown bubble-spinning is a one-step process for fabrication of nanofibrous bundles. METHOD: In this study, polyamide6/66(PA6/66) nanofibrous bundles filled…
The results of studies of sintering of spinel porous ceramics using aluminum and magnesium oxides as initial components without sintering additives are presented. It is shown that the optimal burning temperature range for the production of materials with an open-cellular porous structure is 1700‒1730 °C. It has been e…
Wound silicon carbide nanowires (SiCNWs) were synthesised using carbon nanotube (CNT) template growth method at 1150 °C by calcining a mixture of CNTs and silicon monoxide (SiO) under low vacuum condition, acidification and carbon removal. Results demonstrate that the acidified product is SiC/CNT composite nanotubular…
Magnetic particles are of great interest in various biomedical applications, such as, sample preparation, in vitro biomedical diagnosis, and therapy. For biosensing applications, the used functional magnetic particles should answer numerous criteria such as; submicron size in order to avoid rapid sedimentation, high m…
Magnetic structure of the substituted multiferroics-ferroborates ${\mathrm{Nd}}_{0.9}{\mathrm{Tb}}_{0.1}{\mathrm{Fe}}_{3}{({\mathrm{BO}}_{3})}_{4}$ and ${\mathrm{Nd}}_{0.8}{\mathrm{Tb}}_{0.2}{\mathrm{Fe}}_{3}{({\mathrm{BO}}_{3})}_{4}$ were determined in the framework of a self-consistent refinement of the single cryst…
Zirconium carbide based materials were consolidated via spark plasma sintering and high-pressure high-temperature (HPHT) sintering methods. Fully dense ZrC-TiC compacts were produced by HTHP SPS technique at 1600-1700°C and were characterized by 370 GPa and 23.7 GPa values of Young’s modulus and Vickers microhardness,…
Phenolic resin modified silicone rubber (PMS) was synthesized via hydrosilation reaction between novolak with allyl group and silicone rubber containing Si-H groups. The chemical structure of PMS was characterized by FT-IR, 1 H NMR and GPC. The thermal stability of PMS was characterized through TGA and compared with t…
Sm 2 O 3 /ZnO nanoparticles were prepared via microwave-assisted hydrothermal and sol-gel combustion synthesis. Characteristics of obtained samples were compared in dependence of Sm 2 O 3 content and calcination temperature. Prepared nanostructures were characterized with scanning electron microscopy and X-ray diffrac…
Abstract Paramagnetic magnetic resonance, a powerful technique for characterizing and identifying chemical targets, is increasingly used for imaging; however, low spin polarization at room temperature and moderate magnetic fields poses challenges for detecting small numbers of spins. In this work, we use fluorescence…
Nanomaterials with enzyme-like characteristics (nanozymes) have emerged as potential replacements for natural enzymes due to their potential to overcome several critical limitations of natural enzymes, including low stability as well as high costs in preparation and purification. Herein, we have developed hybrid nanos…
Metasurfaces composed of nanosized silicon particles are considered prospective low-loss media for future planar devices with subwavelength thickness, capable of realizing many optical functionalities, including beam steering, focusing, and holography. Previous studies revealed an opportunity to provide directional sc…
Information on foreign manufacturers of alumina ceramics, mainly fine technical, is presented.

A quantum mechanical approach and local response theory are applied to study plasmons propagating in nanometer-thin gold slabs sandwiched between different dielectrics. The metal slab supports two different kinds of modes, classified as long- and short-range plasmons. Quantum spill-out is found to significantly increa…

Abstract Nanodroplet formation is a critical process in the development of 3D nano-inkjet printing. We show that many-body dissipative particle dynamics (MDPD) can be used to predict nanodroplet formation in nanosized nozzles with good accuracy. A conversion methodology is also introduced to overcome the problem of la…
