Модельная реакция гомомолекулярного изотопного обмена в молекулах СО: 12 С 18О+ 13С 16О « 12 С 16О+ 13С 18О использована для изучения взаимодействия СО с поверхностью промышленных катализаторов ШПК-0.5(0.5% Pd /γ Al 2 O 3 ) и ОПК-2(2% Pt /γ Al 2 O 3 ). Выявлено существование двух областей протекания обмена: высокотемп…
Keywords: oxygen transport membrane, physical vapor deposition\n\nGases with high oxygen content or even pure oxygen can be used in certain future power plants for the combustion process (e.g. so-called OXYFUEL process), or in e.g. production processes in glass and cement industry. Inorganic membrane systems are consi…
Fabric industry has been developing enough to introduce diverse stretch materials to apparel market, so that tightly fitting leggings designs are taking over not only sports wear but also women`s clothing. This study is aimed at developing prototype designs for leggings pants using stretch material that are appropriat…
The calculation method is proposed and experimental investigations on evaluation of the optimal length of the glued zone of a strengthening composite strip to an iron – concrete beam are carried out.
Исследованы процессы фотолюминесценции монокристаллических и наноструктурных оксидных диэлектриков. Разработана физическая модель, созданы алгоритм и программа для моделирования процессов фотолюминесценции с учетом заряжения приповерхностных слоев, процессов переноса, туннельной рекомбинации носителей заряда и особенн…
The method recovery geometric dimensions of worn parts was developed. It is electric arc spraying aluminum alloys produced by surface followed plasma electrolytic oxidation surface finish. These metaloxide ceramic coating with high wear- and corrosion resistance.
The effective use of powder coatings deposited by wire system Fe - Cr - Ni - Ti - Al together with cast iron, under conditions of boundary lubrication was shown. Coatings posess superior triboengineering characteristics sn the range of 1.5 to 5 MPa. It was determsned that friction pair tested at 1 Mpa load operation r…
Polyacrylonitrile (PAN) nanofibers functionalized with amine groups (PAN-NH2) were prepared using a simple one-step reaction route. The PAN-NH2 nanofibers were investigated for the removal of chromium(VI) from aqueous solutions. The adsorption and the kinetic characteristics were evaluated in batch process. The adsorp…
ENSURING THE RELIABILITY OF MAIN PIPELINES WHICH ARE IN LONG-TERM OPERATION A. YANUSHONOK, А. SNARSKIY Republic of Belarus has a developed network of main pipelines. Lifetime of the most operated main pipe-lines in Belarus exceeds design resource. A characteristic feature of the effects of aging is the reduction of pi…
The paper presents solutions of differential equation systems providing parameters of towed vessel autooscillations. The solution have been visualised as graphic charts showing variations of the variables in time. Numerical modeling in MathCad system allows evaluation of influence of separate features of towing on par…
IntroductionNatural materials as cellulose extracted from wood and chitin extracted from crustaceans shells are promising biocompatible materials for tissue engineering applications. (1, 2) The stu ...
It has been shown, that microhardness and yield stress ratio for polymeric materials is defined by their structural state only, which is characterized by structure fractal dimension. Marsh empirical equation gives better correspondence to experiment for polymers and nanocomposites (viscoelastic solids), whereas the mo…
Polyvinyl chloride (PVC) is a very versatile thermoplastic because of its ability to solve a broad range of different concentrations of plasticizer. Phthalates are still the most commonly used plasticizer in PVC, but due to public opinion and legislation against phthalates there is a demand in the market for both old…
Целью НИР является разработка программно-аппаратного модуля для автоматизации измерительного канала по исследованию ТЛ-процессов в облученных широкозонных материалах. Измерение и анализ спектров свечения и возбуждения ФЛ образцов монокристаллов AlN при температуре жидкого азота. \nДля автоматизации использована платфо…
This report concerns part 2 of a project with the aim to propose protective measures for cables and pipelines for bio and natural gas. Part 1 was previously reported in SGC Rapport 2011:239. The wish is to be able to increase the pressure in the distribution networks from 4 to 10 bar without having to retain the safet…
Primjena dubokog hlađenja u toplinskoj obradi razlicitih vrsta celika pokazala se utjecajnom na njihova mehanicka I triboloska svojstva. Ispitivanja utjecaja dubokog hlađenja rađena su i na drugim materijalima kao sto su tvrdi metal, sivi lijev, aluminij i aluminijske legure, magnezij i magnezijske legure itd. U ovom…

In this work we tested the newly assembled ultrahigh vacuum (UHV) system along with the operating characteristics of the plasma source. These studies have been carried out by oxidizing a Pd(111) surface in UHV using atomic oxygen to generate a PdO(101) surface. The PdO(101) surface has then been investigated to observ…
