This research deals with the experimental study on the behaviour of bamboo sticks as steel reinforcement in reinforced concrete beams. A small section of treated and untreated bamboo samples were prepared to study the microstructure of each samples using scanning electron microscope (SEM). There are two types of chemi…
SPARC is a multifunctional, evolutionarily conserved, collagen- and growth factor-binding glycoprotein that is required in Drosophila melanogaster for proper larval development and maintenance of fat body homoeostasis. I have engineered a SPARC RNAi knockdown in the larval fat body, with an emphasis on ultrastructural…
Viscosity, electrical conductivity and deposit weight were determined for Electrophoretic deposition (EPD) Mg2+-, Y3+-, La3+- and Ce4+-doped alumina's ethanolic suspensions prepared at dopant concentration between 350 to 1350 ppm. The concentration of XCly (X, y were: Mg, 2; Y, 3; Ce, 3 and La, 3, respectively) the ch…

The de Haas-van Alphen (dHvA) effect is one of the most powerful and straightforward methods of determining the electronic structure of metals, knowledge of which is essential to understanding the observed physical properties such as resistivity, magnetic structure, and specific heat. Of interest in the field of conde…
Η έρευνα της διδακτορικής διατριβής επικεντρώνεται στη μελέτη της ηλεκτροχημικής συμπεριφοράς νανοδομημένων οξειδίων του τιτανίου σταθερού πάχους και διαφορετικής πυκνότητας φορέων φορτίου σε όξινα διαλύματα και σε διαλύματα ιόντων αλογόνου καθώς και στη μελέτη της ηλεκτροχημικής απόθεσης υμενίων πολυανιλίνης στα οξεί…
The direct recycling process is an alternative method of recycling waste of chip aluminium without melting the materials as compared to conventional recycling technique (secondary production). The cold compaction stage is the most crucial process of the direct recycling process. The billets density, b achieved through…

The specific removal of molecules from various media is an area receiving increasing attention. Affnity membranes, i.e. membranes containing ligands, which can specifically \ncapture target molecules, can meet this demand. One important area, in which the use of affinity membranes will be beneficial, is blood filtrati…
Το νερό ψύξης παίζει σημαντικό ρόλο στην εξαγωγή θερμότητας τόσο από το καλούπι χύτευσης όσο και του μετάλλου που στερεοποιείται κατά τη διάρκεια της Αμέσου Ψύξης Χύτευσης κραμάτων αλουμινίου και χαρακτηρίζεται από πολύπλοκα φαινόμενα βρασμού (στρωματική εξάτμιση, πυρηνικός αναβρασμός) στα στάδια μεταφοράς θερμότητας.…
Nowadays the demand for Gas Insulated Substation (GIS) is increasing over the world for efficient utilization of electric power and space. In this thesis a gas insulated substations is investigated or studied since they are more advantageous though, they use same protective devices or equipment when compared to air in…

Purpose: Dynamic recovery is interesting as it limits the maximal deformation strength of crystalline materials. Due to its small grain size, nanocrystalline Ni reaches its maximal strength after small strains < 0.1. It is shown that dynamic recovery contributes to strain and that its kinetics differs from that of har…
We have developed a quantum molecular dynamics simulation method which can widely search hydrogen systems from an isolated hydrogen molecule to condensed hydrogen liquid, solid and supercooled liquid of strong nuclear quantumness such as zero-point energy and nuclear delocalization. We will report our recent results o…
Uniform and thin polyaniline/carbon nanofiber (PANi/CNF) hybrid nanofibers has been prepared using electrospinning method. Three polymer solutions with different components were examined for synthesis of PANi/CNF electrospun nanofibers. The SEM technique and FT-IR analysis were used to characterize the hybrid nanofibe…
This thesis reports on modelling the morphological of Block Copolymers (BCPs) byusing computer simulation. In this work, the Cell Dynamics Simulation (CDS) methodis used, which is a good compromise between computational speed and physical accuracy.First, it has been performed a 3-dimensional study of diblock copolymer…
Formation of liquid films through the deposition of droplets and spray onto a solid surface was studied experimentally. Experiments were done to observe the coalescence of highly viscous liquid droplets (87 wt% glycerin-in-water solutions) deposited onto a flat, solid steel plate. Droplets were deposited sequentially…
