ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
The hexakis-[30-(10,20,30-thiadiazol-40-yl)phenoxy] (5) and hexakis-[50-oxy-20- methylbenzothiazole] (6) cyclotriphosphazene derivatives were synthesized by Çiftçi et al. in 2017. The structural parameters for the compound (6) and the fluorescence properties…
In the last century, there has been an ever-increasing demand for novel materials namely known as composites. Biological fibers are reinforcement materials of composite structures owing to their economic and ecological advantages. Among these fibers, plant f…
Education structures are among the units in which individuals who have basic education in the family begin to take part in the social structure. While each culture offers different educational approaches in line with its own values, the lack of the same dive…
The metal ions accelerate drug action and efficiency of therapeutic compounds [1]. Metal complexes may inhibit the protein synthesis because of interference in the cellular respiration. Cancer is leading cause of fatality in recent years and remained as a ch…
Transition metal complexes are playing an important role the field of bioorganic chemistry. it has been attempted to investigate the anti-cancer properties of complexes of 2-benzimidazole derivatives formed with various metal atoms [1-2]. In these examinatio…
Bu çalışmada 20 farklı Türk üniversitesinde okuyan birinci sınıf ilköğretim matematik öğretmeni adaylarının sayı öğretme bilgilerinin çeşitli demografik değişkenler tarafından nasıl yordandığı araştırılmıştır. Veriler birinci sınıfın hemen başında, Aydın [1]…
2018 yılı verilerine göre 7,6 milyarı geçen dünya nüfusu her geçen gün artmaya devam etmekte ve bu artışla birlikte insanların ihtiyaçları da her geçen gün artmaktadır. Enerji ihtiyacı ise temel gereksinimlerin başında yer almaktadır. Enerji geçmişte ve gele…
The industrial–style designs affecting today’s perception of designs in a huge velocity has emerged first by the industrial revolution. Although being time–dependent and taking longer time and economically highcost product, the handcraft has allowed the indus…
Climate change and environmental concerns led the investors to search for environmentally sustainable and friendly investments. Green bonds market has emerged as a result of this need. This study aims to analyze this market focusing on market efficiency. Marke…
In order to increase the performance/cost ratio of solar cells, new approaches reducing optical and electrical losses are necessary during the absorption of the light and collection of charge carriers. In this work we focused on various textures on Si surface …
Contact pressure is very critical for wear test. In order to make true wear experiment, counter body, surface, wear load, surface roughness, and the hardness of materials should be selected correctly. Maximum contact pressure forms at hertz point. In this stud…
Over the past decade, gold nanoparticles (AuNPs) have stimulated great interest in various types of sensors because they possess many attractive properties such as optical, electronic and chemical features [1]. In order to gain more intrinsic properties and …
The new material type is ‘cryogels’, which have important potential in biotechnology applications. Cryogels can be obtained from natural or synthetic polymers. It is seen that cryogens prepared from natural polymers become a preferred material group for tissue…
