Demineralized bone matrix (DBM) is a natural, collagen-based, well-established osteoinductive biomaterial. Nevertheless, there are conflicting reports on the efficacy of this product. The purpose of this study was to evaluate whether DBM collagen structure is affected by particle size and can influence DBM osteoinduct…
The improved X-ray optical scheme, the system of registration, and the measurement procedure of the multifunctional synchrotron radiation spectrometer in the dispersive EXAFS mode are described. The results of the spectrometer energy resolution measurements are given. The advantages and disadvantages of traditional an…
Article discusses the current problems in the study of wooden compounds for the construction industry. The present work shows the results of several years of hard work . Based on the evaluation of experimental results, a formula to calculate the empirical relationship estimated carrying capacity compounds bonded steel…
As a class of important conjugated polymers, electroluminescent material of polyfuran possess a lot of merits, including good stability, structure is easy to be modified and controllable electrochemical properties. This study uses ethylene diglycol, diethyl oxalate, 1,3- dibromopropane and so on as raw materials to sy…
The selective insertion of a CH 2 or NH group is achieved through the PCl 5 induced reaction of a CH 2 OH or NHOH group, respectively.
Chitosan edible film is a thin layer of clear packaging made from chitosan edible and biodegradable. Edible chitosan films are stiffer and less elastic, so it should be added plasticizer glycerol. One source of glycerol is inexpensive and easily obtained is crude glycerol from biodiesel production. The purpose of this…
This paper present the results of corrosion resistance of commercial coatings of chromium oxide Cr2O3 deposited by thermal spray on phosphor bronze substrates with three methods of surface preparation: shot blasting with sand, blasting metal with alumina and polishing with abrasive disc, the three surfaces were prepar…
The quaternary reciprocal system comprising fluorides, chlorides, and tungstates of lithium and potassium was partitioned into simplexes using graph theory, and a phase tree of the system was constructed. In the cutting triangles LiF–KCl–Li 2 WO 4 and LiF–KCl–LiKWO 4 by differential thermal analysis, the melting point…
In this paper, quantum chemical calculations of (2e)-3-(3-Bromo-4-methoxyphenyl) -1-(pyridin-2-yl)prop-2-en-1-one were performed by using B3LYP and CAMB3LYP levels of density functional theory (DFT) with 6-311++G(d, p) basis set. Geometric parameters of the title molecule in the ground state were found to be in good a…
In recent years, various types of acoustic metamaterials have been proposed with capabilities for overcoming the diffraction limit. However, typically such developments only consider the acoustic regime or imaging in liquid media. In this paper we show the application of a holey structured metamaterial lens for sub-wa…
We investigate the transport of spin electron through the zigzag-edge graphene nanojunction with a line defect. When the magnetization is zero, the conductance spectra exhibits a well-defined insulating band around the point far away from Dirac point. And the width of the insulating band is exactly equal to the energy…
Magnetic field dependence of the thermopower and Nernst effect of the multiband organic conductor α − (BEDT − TTF)2KHg(SCN)4 is theoretically studied at low temperatures in the charge density wave (CDW) state, to fields of 30 T and several field directions. A theoretical model of quantum interlayer tunneling for the q…
The objective of this paper is the identification of generalised Maxwell slip (GMS) friction model using a new proposed switching function. The GMS friction model is composed of two phases and a switching function, which guarantee the transition from one phase to another. The switching function is based on the frictio…
A study of the temperature effect on the thermomechanical behavior in a shape memory single crystal CuA1Be 0.57% has been carried out. Tensile tests allow us to identify the superelastic effect in the CuAlBe alloy which occurs in the austenitic state (T > Af). We have plotted the stress vs deformation curves for diffe…
The Ensemble Monte Carlo method is used to calculate the transport characteristics of two dimensional electron gas (2DEG) at a ZnMgO/ZnO hetero structure. The spontaneous and piezoelectric polarizations are considered and there is no intentional doping in either material. Numerical Schrödinger and Poisson equations ar…
Correction for 'The magnitude of lift forces acting on drops and bubbles in liquids flowing inside microchannels' by Claudiu A. Stan et al., Lab Chip, 2013, 13, 365-376.
The results of physicochemical examination (chemical analysis, XRD, IR spectroscopy) of the products synthesized in the Ca(OH)2–H3PO4–H2O system under microwave exposure are used to analyze the composition–synthesis conditions–structure–dispersion–properties relationships and to determine the effect of microwave irrad…
The speed with which electromagnetic energy can be wirelessly transferred from a source to the user is a crucial indicator for the performance of a large number of electronic and photonic devices. We expect that energy transfer can be enhanced using special materials. In this paper, we determine the constituent parame…
The propagation of surface waves along the interface between a ferrodielectric and a material that represents an array of amorphous ferromagnetic microwires has been studied. The dispersion characteristic of a magnetically controlled TE wave has been obtained, and frequency intervals have been found in which surface o…
Abstract Amager Bakke (English: Amager slope) is the name of Copenhagen's new waste‐to‐energy‐plant located on the Amager peninsula. Once finished, it will be one of the largest incinerators in northern Europe and will be used for the combined production of district heat and electricity. On top of the waste‐to‐energy…
