Uzunbayır, Berkant

ABSTRACTIn recent years, the utilization of nanotechnology rapidly developed for the wide range of sciences. Nanomaterials shows unique properties and ZnO nanostructures are the most suitable structures for biosensor applications due to their high surface area and high electrochemical activity. In this project first, we have coated zinc film on to Glass/ITO surface by electrochemical deposition method. Then we have transformed the obtained zinc film to nanostructured ZnO by electrochemical anodization method. At the end, we have tried to modify the ZnO nanostructured surface with chitosan for ...Daha fazlası

Biomechanics of acetabular fractures with low energy trauma via finite element modeling and analysis Düşük enerji travmalı acetabular kırıklarının sonlu elemanlar modeli ve analizi

SAMET ÇIKLAÇANDIR

The skeletal system undertakes many tasks such as the movement of the body, mineral storage, and protection of soft tissues. Damage to this structure affects human life negatively. Fractures that occur in the human body is damage to mainly to the bone structure and associated surrounding tissues. Therefore, it is necessary to understand how the fractures are formed and the fracture mechanism. Furthermore, the mechanism of fracture is complicated and worthy of investigation. However, the examination of the bone is difficult because it is a structure covered with tissues like veins and muscles. ...Daha fazlası

Investigation of the cooling system efficiency in aluminum low pressure die casting Alüminyum alçak basınçlı dökümde kullanılan soğutma sisteminin veriminin araştırılması

Yavuz, Hakan

ABSTRACTIn this thesis, the flow rate of air coolers used in low pressure casting method is examined. Low pressure die casting (LPDC) method is used for many types of products. Light alloy wheels, motor housings and pistons are examples of these products. Air-cooling is used to provide directional solidification to avoid casting defects on the casting part. In this study, the flow rate of air-cooling is calculated by using computational fluid dynamics (CFD) methods. After the numerical calculations were confirmed by experimental methods, the affect of the variables on the cooling system flow r ...Daha fazlası

Development of cast aluminum metal matrix composites by additional processes Döküm alüminyum metal matriks kompozitlerinin ilave proseslerle geliştirilmesi

Aybarç, Uğur

ABSTRACTIt is seen that materials used traditionally today are insufficient to meet market expectations. For this reason, the interest on composite material increases day by day. The role of composite materials has become important in sectors, such as especially in automotive and aerospace industries, where a final product weight is of importance.This thesis consists of four application parts. In the first part, a detailed literature review on aluminum metal matrix composites was discussed. In the second part, the appropriate stirring method was searched for the production of aluminum metal ma ...Daha fazlası

The effect of antibacterial photodynamic therapy on healthy fibroblast and keratinocyte cells Antibakteriyel fotodinamik terapinin sağlıklı fibroblast ve keratinosit hücreleri üzerindeki etkisi

GÜLCE KADIKÖYLÜ

ABSTRACTAntibacterial photodynamic therapy is a treatment that occurs in the presence of light, photosensitizer and oxygen. The photosensitizer reacts with the molecular oxygen in the environment when it is stimulated by light at the appropriate wavelength, causing reactive oxygen species at the end. Reactive oxygen species show high cytotoxic effects on cells and cause necrosis or apoptosis. In recent years, the resistance of bacteria to antibiotics has caused infection treatments to become more difficult. This situation has become a threat to human and animal health. Therefore, antibacterial ...Daha fazlası

Development of novel donor and acceptor sam molecules for photovoltaic applications Fotovoltaik uygulamalar için yeni nesil donör ve akseptör kendiliğinden organize tek katman moleküllerin geliştirilmesi

Arkan, Emre

ABSTRACTSurface modification of indium tin oxide (ITO) is a crucial factor to alter the energy level barrier between ITO and perovskite that has direct influence on the charge extraction and recombination at interface. This henomenon has further direct effect on device parameters such as open circuit voltage (VOC), fill factor (FF), and short circuit current density (JSC). This study was base on the synthesis of six novel SAM molecules to be used in fabrication of p-i-n type perovskite solar cells. Since proposed SAMs are of push-pull type molecular nature, contiguous thiophene rings were used ...Daha fazlası

Design and robot operating system based control of a modular robot manipulator Modüler robot manipülatör tasarımı ve robot işletim sistemi tabanlı kontrolü

Kahveci, Aytaç

ABSTRACTIn this thesis, a new design of the modular robot manipulator and its control with Robot Operating System is presented. The modules are designed to have an adjustable twist angle, which enables to create different robot manipulator configurations. Kinematic synthesis on the gripper module is conducted and structural parameters of the gripper is determined. Axis sets on the modules are determined by Denavit-Hartenberg method. Inverse and forward kinematic analysis and singularity analysis are performed. Numerical inverse kinematic solver is proposed for modular robot manipulators with m ...Daha fazlası

Preparation and characterization of carbon-based nanofluids Karbon bazlı nanoakışkanların hazırlanması ve karakterizasyonu

Fidan-Aslan, Tuğçe

ABSTRACTNanofluids are produced by the addition of nano-sized particles to the base fluid in order to increase the thermal conductivity of heat transfer fluids. Preparation of stable nanofluids with high thermal conductivity is a very complex process and their usage in heat transfer applications are related to many important parameters from the stability of nanofluids to their viscosity. Optimization of these parameters is essential for the practical use of nanofluids. The objectives of this study are to successfully preparecarbon-based nanofluids while investigating the stability mechanisms a ...Daha fazlası

Estimation of annual energy production of coupled vertical-axis wind turbines in a semi-complex terrain Eşli çalışan düşey eksenli rüzgar türbinlerinin yarı karmaşık bir sahadaki yıllık enerji üretiminin değerlendirilmesi

Başer, Ferhat Cem Ferhat Cem

ABSTRACTRecent research shows that the vertical-axis wind turbines (VAWTs) can provide up to 6 - 9 times more power generation in the same footprint area when they are sited in proper configurations in contrast to horizontal-axis wind turbines (HAWT). In order to site wind turbines in a field, it is necessary to do a wind resource assessment (WRA). This assessment provide important inputs for the placement, sizing and design detailing of the wind farm. In addition to the correct determination of the site, it is also critical to place the wind turbines in the most efficient way. When the necess ...Daha fazlası

MERVE ÖZKAN

ABSTRACTUrban regeneration projects studied extensively in the world and Europe is a new subject in Turkey. When we look at the examples in the world, their main focus has always been human-oriented. These types of projects should take into account the city's authentic memory and texture, depending primarily on the physical, social, cultural and economic structure. The theme of the project should be determined considering local, social, cultural and physical principles. Ecological values should be decisive in the project's outset, course and outcome. Regeneration projects can actually be consi ...Daha fazlası
