Semiquinones are a class of stable organic radicals with a great potential for design of novel organic electronics and multifunctional materials. Since the radicals are planar, they typically form π-stacks, which stabilise crystal packing and determine magnetic and electrical properties of the crystals. Two types of s…
The objective of this research is to investigate fatigue strength characteristics in a non-combustible magnesium alloy which has relatively small amount of added elements in order to improve extrudability. Fatigue tests were performed under tension-compression loading with stress ratio, R=-1 and frequency of 150Hz at…
(Cu,Ag)2SnS3 (CATS) thin films and solar cells have been fabricated by sulfurization process for the first time and their properties have been investigated. In first experiment, the stacked NaF/(Ag+Cu)/Sn precursor deposited by sequential evaporation of Sn, Ag and Cu elements and NaF followed by crystallization in sel…
Influence of misfit dislocations on mechanical properties of fine pearlite is investigated via uniaxial tensile deformation tests of multilayered composite models composed of ferrite and cementite phases with the Bagaryatsky relation by using molecular dynamics simulations. The analysis models have various spacing of…
High explosive performance and insensitivity are essential characteristics of high energy materials (HEMs) that have been developed in recent years. Explosive performances of energetic materials are influenced by their molecular structure, heat of formation and nitrogen ratio in molecule. Recently, polynitropyrazoles,…
Today fiber reinforced composites such as CFRP (carbon fiber reinforced plastics) have been more and more used for light-weight structural components in various industrial fields such as aerospace. Although there are several sophisticated and practical processing techniques for manufacturing fiber reinforced composite…
Several methods for analysing materials and proteins use highly concentrated beams of X-rays, e.g. SAXS and X-ray crystallography. To evaluate the outgoing beam, it is of high importance to know the light distribution of the incoming beam. Previously, a method for this has been to focus the X-ray beam onto a pinhole i…
Information modeling is one of the leading brunches in designing sphere of possible building objects. In this article the main advantages of BIM technology while creating architectural constructions are described.
We evaluated microforming ability and shape memory behaviors of Ti38Ni50Zr12 (at.%) high formable shape memory alloys (HFSMAs) for the fabrication of the micro folding structure such as foldable pipe structures. In the fabrication method of foldable pipe, at first, Ti-Ni-Zr thin film metallic glass (TFMG) sheet is cre…
Results of birefringence measurement of silica hydrogels prepared in a strong magnetic field (B) are presented. Sodium metasilicate aqueous solutions doped with lead (II) and those with manganese (II) were gellated by keeping them strongly aciditic. Whereas lead (II) exhibits a diamagnetic property as well as silica,…
The ray optics approximation is applied to solving the problem of estimating the electric and magnetic field amplitudes on the axis of a dielectric two-axial ellipsoid with loss that is illuminated by a plane linearly polarized electromagnetic wave. It is shown that the electromagnetic field in the focal range changes…
There is a risk that FW (Filament Wound) composite pressure vessel is exposed to high temperature by a fire accident of Fuel Cell Vehicles. This paper aimed to develop a method of estimating the burst pressure from the temperature and time that FW composite pressure vessel is exposed. Vessels (Type-3, Volume 2.1L, Max…
This thesis focuses on the preparation and the adsorption study of innovative hyper-crosslinked (HCL) polymers and nanocomposites. New microporous nanocomposites were prepared including multi-walled carbon nanotubes (MWCNTs) in styrene/vinylbenzyl chloride/divinylbenzene hyper-crosslinked resins. In order to promote t…
Solid Oxide Fuel Cells (SOFC) as the heat source for a heat engine power cycle can greatly increase the overall efficiency. The maximum efficiency is limited in at least the following ways. All thermal heat engine power cycles are limited by the Carnot efficiency which is a function of the hot and cold reservoirs the…
The distribution of boron in the fuel debris is one of the massive concern for the Fukushima Daiichi NPS decommissioning mainly because its distribution affects the hardness of the debris and possibility of the re-criticality. The distribution might be partially determined by the relocation behavior of the B4C control…
Deconvolution based on Fourier transform is routinely used in a variety of numerical processing: one of these is the removal of noise from signals (f.i. image blurring), echoes in longdistance telephone communications, the finite bandwidth of electronics and analog sensors, etc.. Here, such an approach has been exploi…

The results of the effect of the growth history on Potassium Dihydrogen Phosphate (KDP) crystals growth mechanism are presented in the paper. Crystals were grown in temperature range of from aqueous solutions, saturated at . Two types of the experiments were performed. In both types, after the nucleation at crystals w…
Aquesta Tesi doctoral comprèn la síntesi mitjançant nanoemmotllament (de l’anglès, nanocasting) i autoassemblatge per evaporació induïda (de l’anglès, evaporation–induced self–assembly) i la caracterització exhaustiva de pols i capes de SnO2 mesoporós dopat amb Ni i Cu. L’origen de les propietats magnètiques d’aquests…
