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

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

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

Tattoo dye removal using cold athmospheric plasma (CAP) Soğuk atmosferik plazma (SAP) kullanarak dövme boyası silme

ELİF ÇUKUR

ABSTRACTTattoo has been used as a method of self-expression of mankind since ancient times. The tattoo removal process with primitive methods is based on the process of peeling the skin layer on which the tattoo is placed. Besides being used today, laser is preferred by more people. The tattoo removal with laser is based on disintegration into smaller pieces by breaking the target tattoo pigment by absorbing the transmitted beam. It is then transferred to the nearest lymph node or disintegrated by the macrophages by means of blood or lymph circulation. The most common difficulty with laser tat ...Daha fazlası

Çağatay, Onur Doğanay

ABSTRACTIn this thesis, an Arduino extension board (shield) is designed to take theelectrocardiography (ECG) signals. Firstly, the positive and negative terminals of an ECG signal are selected to determine which input pins are connected to these terminals. User can select one of eight possible inputs for each terminal, which means the user can apply one of the possible 64 channel combinations to inputs of the design. Then a dedicated instrumental amplifier amplifies the signal. The voltagegain of the amplifier can be selectable among available options. The amplified ECG signal is filtered in a ...Daha fazlası
