KUYTAM: Koç University Surface Science and Technology Center

 

A diverse range of chemical, biological, and physical interactions occur at the surface. Hence, it is of great importance to develop methodologies with which surface characteristics of materials and devices can be investigated and/or modified for specific applications. One well-known example involves the development of hydrophobic, in other words, water repellent surfaces. Development of the optimum hydrophobic surface on a specific material would require extensive research about the correct choice of the coating material, its adhesion and durability in adverse environmental conditions, as well as the fabrication procedure. Characterization and modification of the surface further requires a wide range of instruments which can probe the surface at different depth scales from a few atomic layers to microns. Some of the commonly used techniques include electron microscopy, atomic force microscopy, x-ray fluorescence, x-ray diffraction, x-ray photo-emission spectroscopy, Raman microscopy, ultrafast spectroscopy, and mass spectrometry, among others.
Realizing this key role of surfaces in controlling the functionalities of materials and devices, faculty members from the College of Sciences and College of Engineering submitted a proposal to the State Planning Agency (DPT) in 2009 to establish a research center on surfaces: Koç University Surface Science and Technology Center (Koç Üniversitesi Yüzey Teknolojileri Ara┼čt─▒rma Merkezi, KUYTAM). KUYTAM, which received start-up funding from DPT with additional funding from Koç University, was established in 2010 as the first research center in Turkey on surface sciences. Prof. Dr. ─░skender Y─▒lgör (Department of Chemistry) served as the Principal Investigator of the project and the Founding Director of KUYTAM between 2010 and 2013. Dr. Özgür Birer, Assistant Professor of Chemistry, continued as the director of KUYTAM between 2013 and 2015. In September 2015, the current administration of KUYTAM was appointed, consisting of:
-    Alphan Sennaro─člu, Professor of Physics and Electrical-Electronics Engineering, Director
-    Demircan Canadinç, Associate Professor of Mechanical Engineering, Associate Director
-    U─čur Ünal, Associate Professor of Chemistry, Associate Director.
-    Bar─▒┼č Ya─čc─▒, Doctoral Researcher, Coordinator (since 2012)
 
The current KUYTAM team further includes:
1)   Ceren Y─▒lmaz Akkaya, doctoral researcher, PhD in Materials Science and Engineering
2)   Amir Motallebzadeh, doctoral researcher, PhD in Materials and Metallurgical Engineering.
3)   Natali Sözüdo─čru, doctoral researcher, PhD in Materials Science and Engineering
4)   Gülsu ┼×im┼ček, doctoral researcher, PhD in Materials Science and Engineering
KUYTAM was established over a 600-m2 area in the College of Sciences building. It houses a wide range of state-of-the-art instruments dedicated to studies in surface sciences, and provides characterization services for external users from other institutions as well as Koç University faculty members from Sciences, Engineering, Medicine, and Archeology. Currently KUYTAM has 15 affiliated faculty members from Koç University.
Currently, KUYTAM houses 30 characterization instruments, grouped under the following seven laboratories:
1)    Surface Analysis Laboratory
2)    X-ray Laboratory
3)    Spectroscopy Laboratory
4)    Ultrafast Laser Spectroscopy Laboratory
5)    Wet Chemistry Laboratory
6)    Atomic Force Microscopy and Nanoindentation Laboratory
7)    Coating Laboratory
In addition to instrumentation housed in KUYTAM, there are other facilities in Sciences and Engineering, supported by KUYTAM, including a live-cell imaging microscope (used by faculty members from Molecular Biology and Medicine), 5-axis CNC fabrication facility, white-light interferometer, and a reactive ion etching system
