The most important result of the work is the development of the controlled technological process of the nanostructured composite powder materials production. Varying the technological parameters of the material disintegrator, we can influence on the matrix reinforcing rate during the production process.
The results are presented of the magnetic domain structure research in nanostructured heterogeneous rare-earth intermetallide of the Sm-Zr-Co-Cu-Fe type. The domain structure was investigated using optical and magnetic force microscopy. A Comparative analysis was carried out of nano- and domain structure parameters. I…
This article presents the results of a pilot study of experimental stent in comparison to traditionally used. Experi- ments were performed on 20 adult male rabbits weighing 4350–4580 grams. The main study group (10 animals) was performed an experimental unilateral implantation of the stent, as a control (10 animals) w…
O presente trabalho teve como objetivo avaliar o efeito da película de alginato de sódio a 1% aplicadas em maçãs minimamente processadas na forma de esferas durante o armazenamento em diferentes temperaturas. Concluiu-se que, as esferas de maçãs quando conservadas com alginato, teve um comportamento de retardamento na…
This paper presents results that reveal influence of modifiers characterized by different nature and composition and subjected to heat treatment on operational characteristics of single and binary compositions. Interaction between dispersed clay particles and dependence of coating properties on their mass content in o…
The paper shows a principal possibility to develop a technology for production of qualitative regenerated mixtures from old asphalt concrete pavement on the basis of electro-hydraulic cold method applied for their recycling.
Nikesh Gupta,1 Anju Shrivastava,2 Rakesh K Sharma11Nanotechnology and Drug Delivery Research Lab, Department of Chemistry, 2Department of Zoology, University of Delhi, Delhi, IndiaAbstract: Mesoporous silica nanoparticles coencapsulating gadolinium oxide and horseradish peroxidase (HRP) have been synthesized in the aq…
A technology has been developed to obtain porous powder materials on the basis of spherecal powder particles of 12Х18Н10T сorrosion-resistant steel by technological coating deposition on them –condensate from layered and composite Si and (Si + C) or Si and (Mo + Si) nano-layers. Their deformation at points of spherica…
Increasing utilization of engineered nanoparticles in the field of electronics and biomedical applications demands an assessment of risk associated with deliberate or accidental exposure. Metal based nanoparticles are potentially most important of all the nanoparticles in terms of health risks. Microporousalumino-sili…
Los recubrimientos de carburo de cromo sobre acero son un buen candidato para aplicaciones de conformado y moldes de inyección. La alta resistencia mecánica, resistencia química y estabilidad a alta temperatura de la fase Cr3C2 pueden ser compatibles con el intenso desgaste abrasivo y la corrosión en tales operaciones…
It has been established that existing mineral fertilizer spreaders do not fully meet technical requirements. In order to ensure continuous and reliable fertilizer dosing it is necessary to destruct bridges above exhaust ports and facilitate forced fertilizer feed to the spreader.The results of theoretical investigatio…
The dielectric behavior of poly(vinyl alcohol) -PVA- crosslinked hydrogels obtained by the repeated freezing/ thawing (F/T) technique have been investigated by dielectric relaxation spectroscopy (DRS) and differential scanning calorimetry (DSC). The crosslinked polymer is produced by the clustering of chains caused by…
The aim of this work was to build the correct theory of the ion transport in nanostructured materials and estimation of the protection effectiveness of the photocathode of electronic device in terms of the average free path of positive ions reducing the longevity of photocathode. The influence of the exchange of inter…
An analytical model of adhesion forces between the sides of a circular disk-shaped brittle failure crack has been proposed, the adhesion forces being determined by the distance between their sides.
X-ray tomography has become a widely used 3D characterisation technique in materials science either using laboratory tomographs or large X-rays facilities. The advantage of large X-rays facilities is the high photon flux which allows fast tomography to be performed. With fast acquisition CCD cameras, it is possible to…
In this paper we carry out simulation of electrically conductive polymer nanostructured materials by the example of polypyrrole. Implementation of modeling was performed by the Wang- Landau and entropic Monte Carlo simulation based on a model with a fixed valence angle. For modeling polymerization process we used an a…
A complex approach to the choice of color masterbatches for rigid PVC compounds dyeing directly during high-speed extrusion is proposed in this paper. The data is shown to improve the thermal stability of rigid PVC compounds with new organosilicon modifiers. To evaluate the characteristics of pigment masterbatches it…
The results of studies of the dielectric and optical properties of composites based on iron oxides nanoparticles are received. The studies were performed in the temperature range 30 - 100 °C at frequencies of 1 kHz and 1 MHz, and at wavelengths of 600 - 1000 nm.
Features of the growth of large ZnSe and ZnS single crystals by a physical vapor transport with subsequent doping by thermal diffusion from Zn Al melt, as well as ZnO single crystals by the chemical vapor transport technique with the use of HCl as a transport agent and a dopant source, are discussed in the present pap…
This paper investigates the performance of wavelet-based multiresolution motion estimation (MRME) for inbetweening in old animated films using three different MRME schemes. The three schemes are: coarse-to-fine with a wavelet-based MRME, one of Zhang’s MRMEs, and an MRME in the spatial domain. In order to make a perfo…
