In this study, the effects nano-SiO2 and nano-Al2O3 on cement mortars were experimentally studied. The percentage of nano-powders were used as 1%, 3% and 5% into the material. Different types of analysis were used to nano-powder’s impact on the cement mortars.…

In this study, it is aimed to strengthen epoxy with graphene as an adhesive, because of recently the outstanding properties of graphene. For this purpose, the effects of graphene usage on shear strength of modified epoxy-based adhesives were examined. The sh…

Titanium and its alloys are increasingly used in aerospace, automotive and biomedical industries because of their high strength, excellent corrosion, wear resistance and a wide range of mechanical properties. Materials with superior properties are needed in …

In this study, fiber fineness (µm), fiber strength (cN) and elongation (%) values of white and pigmented wool samples taken from female Merino sheeps between the ages of 0-2 years were compared. The results showed that both the fiber strength (cN) and elonga…

Nowadays, as the population increase, various construction projects are made on soils which engineering properties are not suitable. Many stabilization methods are used in order to prevent deformations and loss of bearing capacity on such soils. However, most …

Ceramic materials are characterized by outstanding hardness, extreme compressive strength and elastic modulus, wear resistance, thermal shock resistance, chemical stability and high temperature properties. Therefore they have potential materials to be use at i…

Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…

One of the materials that are increasingly used today in various engineering applications is boron steels. Though boron steels draw attentions with their superior wear characteristics, studies on the tribological properties of these materials is quite limited …

In the study synchronization was studied using an all-to-all network structure in a multiple system of Kuramoto oscillators. Synchronization performance was first investigated in a weakly connected system, and the effects of link strength and number of oscilla…

Eklemeli üretimdeki son gelişmeler ile birlikte, geleneksel tekniklerle üretimi oldukça zor olan hücresel yapılar, daha kolay bir şekilde üretilebilmektedir. Sandviç panellerde çekirdek olarak kullanılabilen hücresel malzemeler, düşük yoğunlukta yüksek rijit…

Beginning from the 20th. Century, Architectural designs and plans are became more complex because of the increasing of functional needs. This appeared an orientation problem for users of the big complex buildings like hospitals, airport, shopping mall, etc. …

Gelişen teknoloji ve artmakta olan nüfus yoğunluğu sebebiyle enerji talebi gün geçtikçe artmaktadır. Artan enerji talebini karşılamak için gerilim seviyeleri yükseltilmekte, yeni iletim hatları inşa edilmekte, ya da var olan iletim hatları akım taşıma kapasite…

In this study, the impregnation of Lareks wood with borax and nanotechnological varnish at various vacuum / diffusion times according to ASTM 1413-76 standards and the changes on technological properties were investigated. Pressure resistance properties were d…

In this study, the literature review on the user perceptual assessment of the colour used in the interior space is analyzed and grouped. Most of the studies are about the perception of colours throughout the space. However, it is thought that the colour combin…

In this study highly porous hydroxyapatite foam fabricated by powder metallurgy method for various sintering temperatures and coated with chitosan after sintering. The solubility of the samples were in Lactated Ringer's solutions for various day. From the re…

In this study, multi-walled carbon nanotubes (MWCNT) in different weight ratios effect on the mechanical properties of modified epoxy based adhesive under an axial load was investigated. 0.25, 0.50, 0.75 and 1 % by weight ratio the MWCNT added epoxy adhesive…

Nanoteknolojik çalışmalar bazı literatürlerde MÖ 2000 yıllara kadar dayandığı bildirilmiştir. Mısır uygarlığında ilk nano ürünler (mürekkep üretiminde) yalın düzeyde de olsa göze çarpmaktadır. Özellikle teknolojisinin gelişmesine paralel olarak günümüz bilim d…

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…

Rubble of destroyed buildings in Turkey is a growing environmental problem, in Ankara only, there are 12 landfills to collect and store them. Adobe is a world common building material; many studies inferred its environmental qualities. This study examines th…

Titanium and titanium alloys are suitable for a variety of applications, with their low density, high strength and high corrosion resistance. Despite strong mechanical and corrosive qualities, titanium use is restricted by its weak friction and wear characteri…
