Manufacturing and Characterization of Peptide Coated Polylactic Acid Based Composites for Various Medical Applications

Metehan ATAGÜR

Within the scope of this thesis, PLA-based composites have been developed and coated with peptide to increase biocompatibility for temporary implant applications and PLA biocomposite materials have been produced. HA and β-TCP were used as additive materials, and PLLA and PDLA polymers were used as polymer matrix. The main purpose is to obtain the composite with the best mechanical properties and to improve the biocompatibility properties as a result of coating this final material with peptide. In the first stage, 10% HA (PLA-10 HA), 10% β-TCP (PLA-10TCP) and 5% HA + 5% β-TCP (PLA-5TCP-5HA) are ...Daha fazlası

Evaluation of Polymeric Composite Material Alternatives for Metal Fulcrum Ring Part Used in Dry Friction Clutches

Ibrahim Can KAYMAZ

As same as in other industries, the automotive industry is one of the industries that expects continuous improvements. In this context, it is very important to integrate new technologies into the industry and to use new, alternative materials for industrial products. With the increase of these studies, cost and weight reduction are improved while serious advantages are obtained by maintaining the product's performance. The suitability of production with additive manufacturing of the fulcrum ring, which is a sub-component of the clutch cover assembly in the dry friction clutch system, acts as a ...Daha fazlası

The impacts of governance on tourism: a macro perspective Yönetişimin turizm üzerindeki etkileri: makro bir perspektif

Can, Yağmur

ABSTRACTIn this study, the effects of world governance indicators on tourism were empirically analysed, from the 2005 to 2018 period. A literature review for governance is included in the first part. The second part contains the definition of world governance indicators (WGI). In the last part, panel co-integration, and causality analysis have been carried out worldwide within 137 countries. As a result of the analysis, a long-run relationship was found only between the change in the number of tourists and the political stability - no violence index. Also, other world governance indexes voice ...Daha fazlası

Investigation of the adhesive-bonded aluminum-polyamide hybrid joints Yapıştırıcı ile birleştirilmiş alüminyum-poliamid hibrit bağlantıların incelenmesi

Batıkan Kandemir, Miray

ABSTRACTToday, environmentally friendly, high-strength and lightweight engineering materials are becoming increasingly important for the automotive and aviation industries. For this purpose, it is critical to combine different materials correctly and to create a reliable hybrid structure. Adhesives have a huge market share among the joining methods due to their low-stress concentration, high formulation possibility, good fatigue resistance, and sealing advantages. However, surface properties and surface treatments play an active role in determining joint performance. In this thesis, the effect ...Daha fazlası

Recycling of dental zirconia residuals resulting from CAD/CAM milling process Submitted

Merve TORMAN KAYALAR

Pre-sintered zirconia blocks stabilized with 3 mol% yttria are the most widely used dental materials in dental prostheses due to their high mechanical strength, high oxidation and wear resistance, high hardness, and excellent biocompatibility. Thanks to the processing of dental blocks with the CAD / CAM process, aesthetic restorations with excellent precision and high surface quality can be produced. However, only 30% of the blocks processed during the CAD/CAM process can be converted into products, while some of the remainder turns into dust and is collected in filters, and the other part bec ...Daha fazlası

Investigation of Manufacturing and Characterization of Radar Absorbing Hybrid Structures

Mohamed Yousef Ali Issa

Significant development of radar systems after World War II has led to studying the interaction between electromagnetic waves at radar frequencies and different materials. One perspective of these studies is to ascertain ways of decreasing reflected waves. However, the applications have not been limited only to defense applications but also to different fields where human beings are exposed to electromagnetic waves to avoid potential health effects due to exposure to electromagnetic waves. Since the discovery of radar systems, many studies have focused on electromagnetic radiation and absorbin ...Daha fazlası

Fabrication of hysteresis-free perovskite solar cells by SAM modified electrode SAM modifiyeli ITO elektrot ile histeresis östermeyen perovskit güneş hücresi üretimi

Yalçın, Eyyup

ABSTRACTEnergy has become one of the main problems of humanity after the industrial revolution and the rapid rise in world population. Most energy resources depend on fossil fuels, which causes environmental problems. Solar energy is a clean and sustainable alternative to the increasing world energy demand. In this context, perovskite solar cells (PSCs) are particularly attractive due to ability to achieve very high efficiencies. The power conversion efficiency (PCE) of PSCs has rapidly grown from 3.8 in 2009 to over 25.5 in 2022, which making it fastest advancing solar cell technology to date ...Daha fazlası

Detection of coal fires in soma with landsat temporal thermal images Landsat temporal termal görüntüleri ile Soma'da kömür yangınlarının tespiti

Köşker, Merve

ABSTRACTCoal is one of the most important energy resources used in many countries for decades to produce energy. A type of fire called coal fires occurs when the coal surface is exposed to sunlight and in contact with oxygen for a long time in coal mine areas where coal is extracted. Coal fires are prevalent and critical incidents for most coal mining areas around the world. Various problems arise due to coal fires in coal mines. These problems affect many factors such as environment, society, economy and security directly or indirectly. Burning coal fire causes the formation of poisonous gase ...Daha fazlası
