Of Silica Gel-Glasses on the 4 I 13/2 → 4 I 15/2 Luminescence Bandwidth of Er3 Ions

Zamirgül KAZAKBAYEVA

The luminescence of Er3 ions in silica glasses synthesized by the direct sol–gel–glass transition method and by melting of activated gel grit using various precursors of optical centers was studied. The formation of complex centers including erbium, aluminum, and alkali metal ions was found to be one way of essentially increasing the half-width of the 4 I 13/2 → 4 I 15/2 luminescence band of these ions. Keyword: complex optical centers; luminescence; rare earth ions; sol–gel method

Experimental analysis of energy, performance and noise emissions for biodiesel fuel obtained from animal waste fat

Hüseyin ÖĞÜT

Animal fats are one of the biodiesel raw materials. In this study, biodiesel was produced from horse fat by transesterification method and the produced biodiesel was mixed with euro diesel at 5 by volume, and experimental fuels in the form of D-100 and D95B5 were obtained. Fuel properties of test fuels were determined. In addition, using the experimental fuels in a single-cylinder, four-stroke, water-cooled diesel engine, the data obtained by investigating the engine performances, energy analysis, and noise emissions were presented with graphics and interpreted. In the experiment results; D95B ...More

The investigation of the use of plant-based wild mustard and boron doped oil as engine lubrication oil in diesel engines

Hüseyin ÖĞÜT

In internal combustion engines, mineral engine oils which serve as lubricants between parts are not used alone due to technical reasons and various additives are made use of for better lubrication. In these additives, liquid boron serves to reduce friction. To reduce the environmental damage caused by engine lubrication oils, it is necessary to improve the properties of biological oils so that they can be used and compete with mineral oils technically. In the study, the use of liquid boron as an engine lubrication oil additive, together with wild mustard oil methyl ester, was investigated. Two ...More

Investigation of engine performance and kit design for the usage of safflower oil as in diesel engine

Hüseyin ÖĞÜT

In Turkey, the consumption of diesel oil is increasing both in transportation and in agricultural fields. In this study, the opportunities of the use of safflower oil, which grow originally in Turkey as a direct fuel in diesel engines, were researched to provide a new alternative for biofuel industry and to popularize the farming of oil crops. In this study, the kit design was completed first, and afterwards safflower oil was exposed to the process of neutralization and laundering, and then turned into standard fuel. For engine performance experiments, reference experiences were conducted by ...More

Effects of using ethanol-biodiesel-diesel fuel in single cylinder diesel engine to engine performance and emissions

Hüseyin ÖĞÜT

In this study, biodiesel was produced from safflower seeds by converting the raw oil obtained through dampening them via the rolling process, roasting at 90 °C and pressing into Safflower Oil Methyl Esther (Safflower Biodiesel) using the trans-esterification method. Experimental fuels were obtained in the forms of D100, B2.5M2.5D95, B5M5D90, B5M2.5D92.5 and B2.5M5D92.5 by mixing the biodiesel fuel obtained from safflower with diesel fuel, adding bio-ethanol at the rates of 2.5% and 5%, and volumetrically in inverse ratio. Tests were conducted to determine the fuel properties of the mixed fuels ...More
