Abstract Heteroatom‐doping into graphitic networks has been utilized for opening the band gap of graphene. However, boron‐doping into the graphitic framework is extremely limited, whereas nitrogen‐doping is relatively feasible. Herein, boron/nitrogen co‐doped graphene (BCN‐graphene) is directly synthesized from the re…
We report a new rapid household microwave method to successfully grow graphene on h-BN flakes without using any catalysts. We obtained a novel uniform multilevel matrix of vertical graphene sheets on h-BN flakes. The unique structure possessed outstanding electron conductivity and thermal properties (29.1 W m(-1) K(-1…
Applications of upconversion phosphors have grown extensively in number during the past decade. Hexagonal sodium yttrium fluoride (β-NaYF 4 ) is known to be one of the best host lattices for upconversion materials. We developed a novel technique for transforming cubic sodium yttrium fluoride (α-NaYF 4 ) phosphors into…
The effectiveness of a phosphoramidate tetraethyl piperazine‐1,4‐diyldiphosphoramidate (TEPP) as a flame retardant on cotton twill fabrics was compared with that of a previously studied diethyl 4‐methylpiperazin‐1‐ylphosphoramidate (DEPP). TEPP was formed in a reaction between two phosphonates and a piperazine then co…
A highly sensitive method for the detection and quantitative evaluation of antimony(III) using the surface-enhanced Raman scattering (SERS) technique is demonstrated. The method is based on the analysis of SERS spectra intensity of antimony bound to phenylfluorone (Sb-PhF). Phenylfluorone is widely used as an organic…
CdSe nanoparticles (NPs) are chemically synthesized in thermotropic ionic liquid crystalline (LC) phase of cadmium octanoate that was used as a nanoreactor. The nanocomposite samples are obtained by the rapid cooling of the LC phase to room temperature. Observed doublet structure in absorption spectra of the nanocompo…
A novel cross-linked poly(methyl methacrylate) (PMMA)-based copolymer was first synthesized by bulk copolymerization of methyl methacrylate (MMA) and 1-oxo-2,6,7-trioxa-1-phosphabicyclo[2.2.2]octane-4-acrylate (PEPAA) at low temperature (80 °C), which is a facile and green method. The structure of PEPAA was confirmed…
A hybrid plant that consists of a gasification system, solid oxide fuel cells (SOFC) and a simple Kalina cycle (SKC) is investigated. Woodchips are introduced into a fixed bed gasification plant to produce syngas, which is then fed into an integrated SOFC-SKC plant to produce electricity. The pre-treated fuel then ent…
The conductivity, current distribution, and radiation efficiency for a variety of dipole antennas constructed from carbon nanotube thread/rope are simulated using Hallén's integral equation for a thin wire applied to the method of moments and are compared to a standard copper wire dipole antenna. Next, the conductivit…
Injury to peripheral nerves can occur as a result of various surgical procedures, including oral and maxillofacial surgery. In the case of nerve transaction, the gold standard treatment is the end-to-end reconnection of the two nerve stumps. When it cannot be performed, the actual strategies consist of the positioning…
We investigated the arrangement of methyl-terminated terthiophenes inside a nanotube by using density functional theory (DFT) including dispersion corrections. After DFT calculations were conducted, a variety of arrangements of the inner terthiophene chains was found, depending on host-tube diameters and the number of…
In this present work, we investigate the electronic transport properties of phosphorus-doped armchair graphene nanoribbon (AGNR) junctions by employing nonequilibrium Green's functions in combination with the density-function theory. Two phosphorus (P) atoms are considered to substitute the central carbon atom with th…
This paper reports work on extrusion foaming of poly(3-hydroxybutyrate- co-3-hydroxyvalerate) with a chemical blowing agent based on sodium bicarbonate and citric acid and calcium carbonate nucleation agent. It includes investigations in the effects of rheological behaviour of the polymer, blowing agent, nucleation ag…
The study of the preparation and application of ZnS nanoparticles (NPs) has been one of the most prominent hotspots in the domain of semiconductor NPs. The ZnS NPs usually exist in two crystallographic forms: zinc blende (cubic) and wurtzite (hexagonal). However, controlled preparation of ZnS NPs with specified crysta…
BACKGROUND: Mesoporous coatings enable incorporation of functional substances and sustainedly release them at the implant site. One bioactive substance that can be incorporated in mesoporous is magnesium, which is strongly involved in bone metabolism and in osteoblast interaction. PURPOSE: The aim of this experimental…
Abstract The polymorphs of nimodipine, Modification I (Mod I), the metastable racemate, and Modification II (Mod II), the stable conglomerate, were evaluated by means of the intrinsic dissolution procedure. For this purpose, a hydro alcoholic solution (ethanol:water, 50:50, v/v) was selected as the dissolution medium,…
Chalcogenide glasses with tetrahedral networks can undergo significant densification under pressure owing to their open structures. The structural mechanisms of pressure-induced densification and the corresponding evolution of physical properties of glassy GeSe 4 alloy are studied over pressures ranging between ambien…
Porous materials with well-defined pore shapes, sizes and distributions are highly desired in many emerging applications, particularly for biomedical materials and devices. However, conventional methods for processing porous materials only demonstrated limited capability in morphological control. One promising solutio…
Abstract Poly(butylene succinate) (PBS) with different ratios of modified talc was prepared by twin-screw extruding. The effect of different loading amounts of talc on the mechanical, thermal, and crystallization properties of PBS was investigated. The mechanical test results indicate that the stiffness of the composi…
We uniformly coated Eu(III)- and Tb(III)-doped yttrium oxide onto the surface of <TEX>$SiO_2$</TEX> spheres and then characterized them by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction crystallography and UV-Visible absorption. 2D and 3D photoluminescence image map profi…
