Determination of phenolics concentration using cross-linked phenol oxidase aggregates
Ertürk, Bedriye Durhan; Bakır, Ufuk; Department of Chemical Engineering (2008)
The main object of the presented study was investigation of the use of cross-linked enzyme (tyrosinase) aggregates (CLTA) obtained from crude mushroom extract for a rapid phenolic content analysis in wines. In addition, a comparison of phenolic characteristics of Turkish red wines was performed. Reproducible and reliable results in total phenolic measurement were obtained with CLTAs similar to pure tyrosinase and tyrosinase obtained from crude mushroom extract. Measurement of total phenolic content is possi...

Determination of susceptibility to intergranular corrosion in AISI 304L and 316L type stainless steels by electrochemical reactivation method
Aydoğdu, Gülgün Hamide; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2004)
Austenitic stainless steels have a major problem during solution annealing or welding in the temperature range of 500-800 °C due to the formation of chromium carbide, which causes chromium depleted areas along grain boundaries. This means that the structure has become sensitized to intergranular corrosion. Susceptibility to intergranular corrosion can be determined by means of destructive acid tests or by nondestructive electrochemical potentiokinetic reactivation (EPR) tests. The EPR test, which provides q...
Determination of residual stress state in SAE/AISI 8620 carburized steel by non-destructive testing methods
Kaleli, Tuğçe; Gür, Cemil Hakan; Department of Metallurgical and Materials Engineering (2017)
Industrial performance of the carburized steels is mainly dependent on the residual stress state in the carburized layer that is controlled by the process parameters such as carburizing temperature and time. Non-destructive evaluation of the material properties and residual stress state has been gained importance for industrial applications due to its advantages such as measurement speed and complete control possibility of the components by automation. The aim of this thesis is to investigate the efficiency...
Determination of ion dose and profiles in Ge-74 and Sn-120 implanted silicon layers by PIXE, NAA, RBS and SIMS
Belin, B; Bode, P; Turan, Raşit; Van Meerten, TG (2004-01-01)
Implanted Ge-74 and Sn-121 concentrations in silicon (Si) layers were investigated by particle induced X-ray emission (PIXE), instrumental neutron activation analysis (INAA), Rutherford backscattering spectrometry (RBS) and secondary ion mass spectrometry (SIMS). Slight differences were observed in the results obtained. It was shown that PIXE and INAA are as powerful as the traditional RBS and SIMS spectroscopy for the investigation of thin layered Si.
