Metallurgical and Materials Engineering
(2004)
The main fields of operation for Metallurgical and Materials Engineering are production of engineering materials, defining and improving their features, as well as developing new materials to meet the expectations at every aspect of life and the users from these aspects. Founded in 2004 and graduated its 10th-semester alumni in 2018, our Department also obtained MÜDEK accreditation in the latter year. Offering the opportunity to hold an internationally valid diploma through the accreditation in question, our Department has highly qualified and experienced Academic Staff. Many of the courses offered at our Department are supported with various practice sessions, and internship studies in summer. This way, we help our students become better-equipped engineers for their future professional lives. With the Cooperative Education curriculum that entered into effect in 2019, students may volunteer to work at contracted companies for a period of six months with no extensions to their period of study.

English Translation and Interpretation
(2001)
Since 2001, our Department has offered education at an extent that matches the similar Departments of European Universities, with a program that involves theoretical and practical courses within the frameworks of translation and interpretation. The goals that we aim our students to reach involve the utilization of knowledge, behaviors and equipment, interpersonal operation in interpretation, the management of the process of production, expertise in language skills with respect to fields and general culture, and access to information. Our students have no difficulty in being hired upon graduation, having gained an awareness regarding the expectations and the conditions of the professional life through our strong cooperation with the national and the international sector. With French and Russian courses offered for 4 years, our students steal the spotlight in the market, having obtained a C-Language Certificate. Our graduates are employed as freelance interpreters, institution interpreters, regulators as multi-layered language experts, terminology experts, subtitle experts and web localization experts.

Abstract

Titania (TiO2) nanostructures were produced via hydrothermal method using amorphous TiO2 powders synthesized by the sol-gel precipitation process. The hydrothermal system was isolated from the environment and hydrothermal reactions were allowed to execute at 130 °C for 36 h at autogeneous pressure, and at a stirring rate of 250 rpm. Scanning electron microscopy (SEM) analysis revealed that TiO2 nanofibers formed instead of nanotubes upon utilization of amorphous TiO2 precursor. After hydrothermal synthesis, the powders were acid treated by HCl several times. X-ray diffraction (XRD) analysis identified that the synthesized powders were Na-titanate and remained Na-titanate even after subjecting to acidic treatments several times. The photocatalytic performance of the powders was evaluated by degradation of methylene blue (MB) solution in UV illumination. Results were compared with nanotubes which were synthesized previously using P25 commercial titania powder and have shown that TiO2 in tubular structure offers better photocatalytic performance for the degradation of MB solution under UV illumination as compared to fiber-like structure.
