Σκοπός της παρούσας έρευνας είναι η μελέτη της επίδρασης των βλαστικών κυττάρων του λιπώδους ιστού, όταν αυτά χορηγούνται με τη μορφή του στρωματικού αγγειακού κλάσματος, στην κατά δεύτερο σκοπό επούλωση οξέων δερματικών ελλειμμάτων ολικού πάχους σε επίμυες. Για το σκοπό αυτό χρησιμοποιήθηκαν 24 επίμυες, από τους οποί…
Electrochemical deposition is a very efficient method for producing many types of modern materials. This method is not expensive and does not have a limit for sample size. In our work, the preparation of Ag and Au nanowires is presented. The obtained nanowires had different diameter and length, which were tunable by t…
Abstract The quality of structural steels currently available is discussed. Their characteristics are regulated by new standards for steel and iron structural components and in design standards. Such components include beams, pipes, and rolled components for use in buildings, bridges, and other structures. The mainten…
Current insulation solutions across multiple industries, especially the commercial sector, can be bulky and ineffective when considering their volume. Aerogels are excellent insulators, exhibiting low thermal conductivities and low densities with a porosity of around 95%. Such characteristics make aerogels effective i…
Hypothesis: Surface and structural modification of membranes in order to improve their filtration properties have been one of the vast research areas in the field of membranes in recent years. Nanomaterials are most widely used for modifying the surface and structure of the membranes. In this study, carboxylic acid an…
Abstract The theoretical and experimental analysis of phase equilibria in the Zn–Se–Fe ternary system is carried out with the use of X-ray diffraction analysis and inductively coupled plasma mass-spectrometry. Information is acquired on monovariant equilibria in isothermal sections at temperatures of 730, 814, and 107…
Abstract Films of carbon-polymer nanocomposite polyacrylonitrile/single-wall carbon nanotubes (PAN/SWCNTs) with various filler concentrations varying from 0.5 to 30 wt % are synthesized. It is found that use of fillers as the SWCNTs in a polymer composite based on PAN significantly influences the mechanical properties…
Abstract— The aim of this work is to study the effect that the process of iron and carbon doping of a GaN epitaxial layer on sapphire can influence (affects) on the features of growth of epitaxial films and their dislocation structure. The following research methods are used in the study: secondary ion mass spectrosco…
We investigated the magnetic structure in epitaxial Fe films on GaAs(001) by taking advantage of planar Hall effect combining with static and dynamic magnetization measurements. The depth dependence of the magnetic structure was evidenced as a result of competition between in-plane interfacial uniaxial and bulk cubic…
This study was conducted to evaluate the antagonistic activity of Rosmarinus officinalis L. (Rosemary) essential oil at different concentrations (500, 1000, 2000 or 3000 ppm) against three different fungi (Aspergillus niger, Penecillium notatum and Candida sp.), these isolates were isolated from air. On the other hand…

Polipropilen (PP)-selüloz nanofibril (CNF)\nve Fusabond Hibrit kompozitler çift vidalı ekstruder kullanılarak\nhazırlanmıştır. Ticari uyumlaştırıcı kimyasal PP/CN…
In this study, first principle calculation based on density functional theory was applied to graphene nanoribbons (GNRs), which is divided to three groups for the number of carbon dimers, with local large bending deformation so as to reveal the effects of the bending deformation on the electronical properties of GNRs…
Four diffuser materials with different base polymers and fillers have been investigated for the purpose of direct integration into sensor packages. Therefore, the most important properties, namely transmission and scattering as well as behavior under the influence of heat, were analyzed. UV/Vis measurements before and…
Phosphor converted white light emitting diodes have been widely used for general lighting. Due to the massive applications in the markets, the reliability issues of pc-WLEDs attract more and more attention. In this study, 5730 commerical pc-WLEDs were modeled with a Monte-Carlo ray-tracing simulation. The influence of…
Water-resistant luminescent polymer composites with CsPbBr3quantum dots in Cs4PbBr6crystals (CsPbBr3@Cs4PbBr6) are reported. These color-converting materials enable a narrow-band green emission with fast dynamics and are therefore a potential alternative to phosphors, mainly for applications that require a fast modula…
Abstract The theme of the paper is to design the capacity of a P + 6E construction with reinforced concrete frame structure and determination of the basic force-displacement on the top. Drawing the cutting force - the displacement at the top requires a non-linear bias of the pushover type. The non-linear static calcul…
A model capable of describing the optoelectronic response of tandem photovoltaic cells is introduced, employing commercial software provided by Lumerical Solutions Inc. Specifically, a four-terminal thin perovskite/silicon architecture is studied, with special focus on the optical properties of the interlayer, and als…
This paper addresses the modelling of PMSM under high frequency PWM control. The high frequency components of input voltage have different responses in terms of induced current and iron losses, due to eddy currents in the magnets, phase conductors and in the core lamination. Both inductance and HF iron loss behavior o…
Ferroelectric random-access memory (FeRAM) is one of the promising candidates for future nonvolatile memory devices. Integration of higher density FeRAM requires more robust electrode material for capacitor reliability with easy etching capability to replace Pt electrodes. In this study, pulsed laser deposited (PLD) o…
