The binary and ternary complexes of the type ML and MLA were synthesized where M= Cu (II), Ni (II), L = Phosphonoformic acid and A = Alanine, phenyl alanine, ethylene diamine, 1, 10-phenanthroline, oxalic acid and Malonic acid. The complexes were non-electrolytic. The elemental analysis, magnetic measurements, conduct…
Polyhedral oligomeric silsesquioxane (POSS) are an innovative class of organosilicon compounds suitable for formulation of advanced organic-inorganic hybrid materials. Nanocomposites based POSS found application mostly in high-temperature resistance and fire-resistance materials. POSS are characterized by a three dime…
The oxide scale produced in the steel making process should be considered due to its after effect on surface quality. For manufacturing Commercially Pure Titanium (CP Ti) hot roll band, the HSM should tune many of the process parameters to adapt for the physical properties of titanium. In this study, the occurrence of…
The work presents an analysis of applying various steels for manufacturing motor-car bodies. There is a brief description of cold-rolled sheet steels RRST 1405 produced according to the standards DIN 1623 and DIN 1541; UST 1203, UST 1303 according to DIN 1624 and DIN 1606; ST 4, 08MnSiAlTi, 07MnNbAl and also a classif…
V pricujocem delu sem se ukvarjala z vgradnjo ATH nanodelcev v akrilne sisteme. Nanodelci so bili sintetizirani po sol-gel postopku na Nanotesla Institutu v Ljubljani. Za karakterizacijo delcev smo uporabili razlicne metode. Velikost delcev smo dolocili z BET metodo, porazdelitev in velikost z DLS, sestavo smo proucil…
The radon concentrations and radium effective contents in truffle samples collected randomly from Samawa desert in southern Iraq, have been measured using both techniques, active (RAD-7) and passive (LR-115 type II nuclear track detectors). The concentrations measured by both techniques are found to vary from…
Методом анодной электрокристаллизации получены оксиды p-элементов: таллия и свинца, допированные соединениями Mo(VI). Показано, что в отличие от смешанных оксидов марганца и молибдена (Mn1 - xMoxO2 + x · nH2O), получаемых электроосаждением, анодные осадки на основе оксидов таллия и свинца включают в себя лишь относите…
Pada era modernisasi ini banyak komponen-komponen mesin yang dituntut memiliki kualitas dan ketelitian produk tinggi, oleh karena itu dibutuhkan proses-proses manufaktur yang tepat. Dalam hal ini pengecoran logam merupakan salah satu metode untuk menghasilkan suatu produk. Salah satu dari metode pengecoran logam adala…
Soil samples were collected around two cement companies are Sinai and Suez cement factories in Egypt, which are both producing factories of cement in Egypt. The natural radioactivity concentrations are the mean absorbed doses of 40K, 238U and 232Th at various selected locations were determined. The mean radionuclideÂÂ…
Neste trabalho são apresentados resultados que concernem ao estudo da magnetorresistência gigante (GMR) em amostras de multicamadas de Co/Cu com larguras de ordem micrométricas. Para isto, filmes com largura macroscópica foram depositados por sputtering e empregou-se técnica de litografia ótica, associada à corrosão ú…

On board generation of clean hydrogen is a contemporary research area for its potential application in fuel cell driven vehicles. Hydrogen can be generated from different sources, i.e. ammonia, hydrocarbons, alcohols etc., and every source have its pro and cons. In this thesis, partial oxidation of methanol is reporte…
Ultra-high molecular weight polyacrylonitrile (UHMWPAN) powders were synthesized by aqueous suspension polymerization with different AN/IA ratios using α,α’-azobisisobutyronitrile (AIBN) as initiator and Polyvinyl alcohol (PVA) as the disperser at 70℃ for 2h. The thermal properties, structural characteristics, element…
The work objective is to evaluate the effective conductivity coefficient of a material with parallel cylindrical inclusions with equal diameters. Since an analytical solution of the conductivity equation is quite difficult, we apply a mathematical model, in which a random motion of the imaginary heat represents the pr…
Electroless copper deposition is a promising alternative technique for interconnect fabrication because it may be difficult for electrodeposition to fill features that are 10 nm and smaller. An electroless copper bath of low toxicity and mild operating conditions with dimethylamine borane (DMAB) as reducing agent was…
Tin/lead plating technologies have been used for unsurpassed solderability and in electrical and electronic equipments eliminating the potential for tin whisker formation. The present study is aimed at recovering of Cu, Sn, Pb, respectively, from the copper scrap coated with Pb and Sn. In the recycling process, tin wa…
Families of layer-wise and equivalent single layer advanced finite elements for the geometrically nonlinear analysis of smart multilayered plates are formulated in a unified framework. The proposed modeling strategy reduces the multifield problems to an effective mechanical plate by the condensation of the electromech…
The article describes the possibility of increasing consumer properties (sound absorption, thermal stability, etc.) mixtures used for finishing of residential and non-residential premises, due to their modification of dispersed fillers.
Today, sulfide from raw fuel gasses is removed mostly via absorption in a sodium hydroxide stream in a wet scrubber. This creates a spent caustic stream (SCS), which is treated via various approaches. However, these treatments have some disadvantages such as a high operating cost, a high chemical usage or low robustne…
Nowadays, piezoelectric materials are widely used in sensor technology. Amongst variety of types, piezoceramics have been demonstrated as efficient tools for sensing applications. Piezoelectric ceramics are more versatile so that their physical, chemical, and piezoelectric characteristics can be tailored to specific p…
