The study of the karbotitanosianirovanie process in multycompounds melt salts, in radio-frequency electromagnetic field was considered. At was shown the possibility of checking of "diligences" melt salts by means of acoustic emission experimental method.
In work results of theoretical calculation of basic elements of the closed technological package for coating composite coverings are brought.
The problem of finding maximal flow in networks with barrier reachability is considered. It is shown that existing algorithm for solution this problem can't find solution for all networks. New algorithm is suggested.
The fracture toughness of a glassy polycyclo-olefin (PCO) was investigated by the essential work of fracture (EWF) method using a double-edge notched specimens. It was shown that the PCO follows the EWF concept in the temperature range between room temperature and glass transition temperature Tg where the ligament yie…
Hybrid poly(ether-urethane)acrylate (PEUA)/titania (TiO2) microcomposites were prepared using a novel method that includes a swelling of different photo-crosslinked PEUA networks in concentrated tetraisopropoxytitanate (Ti(OiC3H7)4 or TIPT) precursor solution in organic media followed by the hydrolysis of covalently b…
A series of main-chain chiral polyketones have been synthesized through condensation polymerization of a dihalide and a diketone with optically pure binaphthyl moiety as linkage in the polymer backbone. The solubility of the polymers can be easily enhanced by substituents at the alpha position next to the carbonyl gro…
Macromolecular components of pharmaceuticals represent a segment of small quantity but high value within the polymer market. The knowledge built in these systems act as driving force for other polymer fields. Their conventional role, the coating and bonding, has been extended recently due to new challenges.
Results of unseat moment investigations for metal-polymeric turning pairs are cited. Testing machine and testing technique are described. Fluent features of thermal and power load conditions to friction coefficient are descripted.
Nano level technologies for wear resistance increase were considered for Different materials: cemented carbides, high speed steels and polymer composites.
In article are presented theoretical and experimental studies of the motion grain material on sieve the system cleaning of the combine harvester with dynamic leveling. The comparison of the theoretical and experimental studies is made.
It is given to the method calculation of wear resistance of WC, phase Laves, superstructure and composite materials on their basis. Received results are discussed.
In the presented work on the basis of Reynolds's equation the method of final elements solves a problem about distribution of pressure in lubricant film. Influence of rotation on distribution of pressure and on bearing ability of the bearing is investigated. Comparisons of key parameters with theoretical and experimen…
The axiomatic description of a considered problem is made. Stages of formalization of indistinct expert knowledge are considered.
In the given work with purpose of geometry restoration and hardening of the form-building tools without removing from the machine tool considered the opportunity of protective wear resistance coatings production using discrete ELAC technology (electro-acoustic coating).
This article introduces a computer program EOSupport (Experimental Optimization Support) written by the author which helps to design experiments, process experimental data, calculate regression coefficients and compute statistical criterias for testing experimental results. The article also contains results of two suc…
The Langmuir-Blodgett technique was utilized and optimized to produce closed monolayers of cobalt-platinum nanoparticles over vast areas. It is shown that sample preparation, "dipping angle", and subphase type have a strong impact on the quality of the produced films. The amount of ligands on the nanoparticle's surfac…
Dextran and PEG-coated iron oxide nanoparticles (NP), when suitably modified to enable conjugation with molecular targeting agents, provide opportunities to target cancer cells. Monoclonal antibodies, scFv, and peptides conjugated to 20 nm NP have been reported to target cancer for imaging and alternating magnetic fie…
A simple, cost-effective, and safe growth technique, that is, mist chemical vapor deposition method, has been applied to the growth of single crystalline ZnO thin films on a -plane sapphire substrates. A water solution of zinc acetic acid and compressed air were used as sources, and the growth was performed at 800 °C.…
This review presents the elastic theory of low-dimensional (one- and two-dimensional) continua and its applications in bio- and nano-structures. First, the curve and surface theory, as the geometric representation of the low-dimensional continua, is briefly described through Cartan moving frame method. The elastic the…
