A resistencia a corrosao dos acos inoxidaveis duplex e super duplex solubilizados foi investigada em diferentes concentracoes Cl - (3,5 a 7 %) e diferentes faixas de pH (4,0 a 6,9). Foram utilizadas tecnicas eletroquimicas para caracterizacao da resistencia do filme passivo que foi avaliado a partir do potencial de ci…
The suitability of defatted flaxseed flour for cracker preparation was investigated in this study. The defatted flaxseed flour was blended with refined wheat flour in the ratios of 100: 0, 95: 5, 90: 10, 85: 15, 80: 20, 75: 25 and 70: 30. The developed products were packed in laminate aluminium pouches and stored for…
1H NMR peak intensities, 1H NMR diffusion measurements and TGA experiments were used to clarify the fate of the dispersing molecules, block copolymer Pluronic F127, during preparation of single-wal ...
Тhe method of the solution of the stationary plane thermoelastic problem of a multilayer plate with elastic links between its layers is proposed. It is assumed that tangential (normal) elastic links between two neighboring layers exist if the difference between the horizontal (vertical) displacements of points of the…
Hydrogel is a macromolecule three-dimensional network made of hydrophilic polymers, which is soft and has good elasticity. Hydrogels have a wide range of potential applications in tissue engineering, drug delivery and biosensors. In this paper can be applied to a biomedical polymer material polyvinyl alcohol as matrix…
Motor transport and road maintenance are the determining factors of environmental pollution in the roadside zone. The main acceptor of pollution in this case is the soil. In connection with the complexity of the application of instrumental control methods, it is perspective to carry out the monitoring of roadside terr…
Carbon dioxide, generated largely from combustion of fossil fuels, is one the most discussed gases of present time. It is one of the major greenhouse gases and also the most abundant and not utilized carbon source. This work is focused on photocatalytic reduction of carbon dioxide to not only reduce its emissions, but…
The desire to utilize renewable resources and avoid wastes drives us to develop new concepts for material design. Non-edible starch feedstocks and starch bioplastic wastes were previously considere ...
The alumina graphite composite were successfully prepared by powder metallurgy technique. Through this method low energy milling machine was used. The effect of the microstructural and compaction were determined according to different milling time in this study. The different milling time that involved were 15, 30, 45…
We report structural and electrical studies of Pr0.6Sr0.4Mn1-xBixO3 (x=0,0.1 and 0.2) manganites. In manganitesMn ions play a crucial role in shaping the physical properties. Possible reasons for the observed structural, changes of resistivity behavior with Bi doping are discussed. Replacing trivalent Bi ion with Mn i…
Interface engineering has been proved to be a practical strategy to enhance power conversion efficiency (PCE) and stability of perovskite solar cells. Recently approaches involving ultra-thin layer deposition and vacuum-processing, while improving PCE, increase the processing complexity, and thus an overall cost. In t…
In this paper mechanical behaviour of shell powder is reinforced to poly vinyl chloride with respective percentage of epoxy composite. Coconut shell process laminates and poly vinyl chloride powder laminates are excellent materials to reinforce with epoxy to sustain advanced structural applications due to their high s…
In the recent years, constant quest for novel glass and glass-ceramic materials for their target application such as cathode material in Li-ion batteries is present. Special attention has been devoted to lithium iron (vanadate) phosphate glass- ceramics and more recently to pure polaronic glass- ceramics for this purp…
Fusarium graminearum is a soilborne and seedborne fungus that can cause significant losses on maize through a variety of different diseases, including seedling blight. Seedling blight is usually managed by utilizing fungicide seed treatments, but unfavorable germination environments and high levels of inoculum can sti…
The documents in STRESA are accessed in hierarchical mode. The general structure for experimental facilities is: 1) Facilities; 2) Tests or Experiments; 3) Documents and/or Data. For each of these experiments an arbitrary number of documents/data have been stored. The documents/data have different levels of protection…
This paper presents the results of mechanical tests carried out on two different commercially available cobalt alloys applied indental prosthetics for the production of frame dentures. The test samples were obtained by the method of investment casting using as a charge pure primary materials and pure primary materials…
In the in-service inspection of sodium cooled fast reactors, an examination by continuous leak monitoring is considered for components constituting a sodium boundary. The continuous leak monitoring examinations are premises in a LBB (leak before break) being established. In previous LBB evaluation, the axial crack of…
Instead of usual approach, applying displacement-displacement Green’s functions, the momentum-momentum Green’s functions will be used to calculate the diffusion tensor. These functions enter into Kubo’s formula defining diffusion properties of the system. Calculation of the diffusion tensor requires solving of the sys…
In this thesis, complex anisotropic materials are investigated and characterized by generalized ellipsometry. In recent years, anisotropic materials have gained considerable interest for novel applications in electronic and optoelectronic devices, mostly due to unique properties that originate from reduced crystal sym…
