Photovoltaics is a direct way to harvest sunlight into electricity using solar cells made from both organic and inorganic semiconductor materials. Organic solar cells have lower efficiency but have the potential to become low cost photovoltaic technology. Lack of understanding of charge transport mechanisms arises due…

Variation of electrolysis process in the study conducted by current variation and variation in salinity levels. KOH electrolyte use disstatic(potassium hydroxyda) with voltage variations(1A; 2,5A,3A) and variations in salinity levels(10%, 20%, 30%). The electrodes use dare stainless steel as a node and cathode. It wil…
ZnO thin films were prepared by radio frequency (RF) reactive magnetron sputtering at varying deposition conditions. The effects of RF power (from 40 to 90 W) and substrate temperature (from 100 to 200 degrees C) on the grain growth behavior, surface morphology evolution, and the structural and optical properties of t…
This article has a purpose to give a brief review of usage of composite materials in the structure of modern civil aircraft. The current condition of civil aviation was analyzed, serious problems were determined and possible achievements in the future were discussed. Advantages and disadvantages of composite materials…
Electrospinning is an efficient and versatile technique to fabricate polymer nanofibers. In this study, ultrafine Nylon 6 nanofibers were successfully fabricated by the electrospinning technique. The electrospinning voltage, solution concentration and flow rate are three parameters that have been reported to have effe…
Rosette Nanotubes (RNTs) are a class of self-assembled organic nanomaterials generated through the spontaneous hierarchical organization of guanine-cytosine (G˄C) bases with a built-in self-assembling ability. Driven by non-covalent intermolecular forces in solution, G˄C bases self-assemble into six-membered macrocycl…
Fe2+-, Fe3+-, and Sn4+-based complex oxides, namely, Fe2GeO4, Ca Fe2O4 and Ca2SnO4 nanopowders were prepared via single -step mechanosynthesis performed at room temperature. The mechanically induced formation of a nanooxide product phase was followed by XRD,57Fe Mössbauer spectroscopy, and NMR. It is demonstrated that…
Metamaterials are artificial media designed to achieve exotic electromagnetic responses that are not available in conventional materials. Engineering the black body thermal emission using metamaterials promises to impact a variety of applications involving thermophotovoltaics, energy management and coherent thermal so…

The assembly of nanoparticle building blocks into more complex nanostructures has important applications in analytical chemistry, materials science, medical science, optics, and electronics. Due to its exquisite specificity and programmable nature, DNA has emerged as a very promising biomolecule to facilitate the asse…
In spite of many efforts given during the last decades to find new alternative photocatalytic materials, titanium dioxide (TiO2) still represents the most widely employed semiconductor for photocatalytic applications, being photoactive, cheap, easily available, non-toxic, inert and, most of all, chemically stable. How…

In general, the physical properties of polymers intimately depend on the morphology. In this dissertation we investigated the role of morphology on dynamic processes that occur in complex systems possessing appreciably different morphologies: (1) diblock copolymer/homopolymer blends; (2) miscible blends of linear chai…
The transfer of micro and nano patterns into a photosensitive material has a large number of technological applications. One of this techniques is known as optical lithography and is widely used in the fabrication process of integrated circuits (IC). The exposure, as one of the most important steps of a lithography pr…
Résumé : Les copolymères à blocs sensibles aux stimuli (SR-BCPs) et leurs assemblages, tels que les micelles, les vésicules et les hydrogels, peuvent subir des changements physiques ou chimiques en réponse à l'évolution des conditions environnementales. Pour un excellent SR-BCP, habituellement, de légères modification…
Objective. The aim of the study was to examine the fracture strength of fully anatomical monolithic high translucent Y-TZP, yttria-stabilized tetragonal zirconia polycrystal, crowns and to compare them with monolithic low translucent Y-TZP crowns in different thicknesses. \nMaterials and methods. 80 standardized crown…
Nowadays, the civil aeronautic industry is subjected to many standards aiming to the reduction of its environmental impact. This leads industries to elaborate new materials, lighter and more efficient, to replace for example parts of the turbojets which are currently made of nickel based super-alloys. Thermostructural…
Droplets exist widely in our everyday life and various industries. Numerous studies have been done to explore droplet systems and among them Gibbsian surface thermodynamics is a powerful means to investigate these highly curved systems. Due to the development of modern technologies and the introduction of novel materi…
