Dr. Aligul Buyukaksoy
Gebze Technical University 

Overview:Intermediate Temperature Solid Oxide Fuel Cells

Aiming at eliminating the long-term performance loss caused by microstructural and chemical degradation of the conventional SOFC , significant progress has been made on  lowering the operating temperature of SOFCs down to 550-700 °C. This, on the other hand, brings about a whole new set of challenges that originate from the slow electrode kinetics and ionic transport at these temperatures. In this lecture, first, a background on the operating principles, techniques of fabrication and characterization of conventional SOFCs will be provided. Then, the novel materials, fabrication techniques and cell designs that have been proposed for IT- SOFCs will be summarized.

 Aligul Buyukaksoy obtained his PhD from Missouri University of Science and Technology (formerly University of Missouri-Rolla) in 2013 with a thesis on the development of composite electrodes for solid oxide fuel cells . He was the recipient of Alberta Innovates – Technology Futures/ Eyes High, a postdoctoral fellowship program at the University of Calgary where he continued his research on SOFCs . In 2016, he joined   Gebze Technical University as a faculty member . Dr. Buyukaksoys  research interests include the development of novel nanostructured electrodes for intermediate temperature SOFCs, SOFC device design, understanding of the electrochemical reaction mechanisms in SOFCs.

Dr. Meltem Sezen
Sabanci University


“Focused Ion Beam Microscopy”

The focused ion beam (FIB) has gained widespread use in fundamental materials and  technological applications in recent years  because it offers both high-resolution imaging and flexible micromachining  at the nanometer–micrometer scale. In the simplest case, it provides a fast and  efficient sample preparation technique for TEM where the thinning can be positioned  with a great precision. TEM combined with FIB based sectioning and tomography provide useful information with regard to morphology and elemental distribution in material system comprising sub-components at nanoscale, including interfaces. In this lecture, novel sample preparation methodologies as well as FIB tomography will be introduced and discussed. The complementary analysis will also be presented using HR-TEM imaging coupled with HR-SEM imaging for varying scales, from micron to atomic.

Meltem Sezen received her PhD degree from Institute for Electron Microscopy of Graz University of Technology, Austria in 2009. She then continued working as a postdoctoral research fellow in Graz Centre for Electron Microscopy (ZFE) since 2011. She is currently working as a researcher at the Sabanci University Nanotechnology Research and Application Center (SUNUM). Her primary research interests include Focused Ion Beam technologies; Dual-Beam (FIB-SEM) instruments; correlative electron/ion beam irradiation damage analysis on conjugated polymers and organic semiconductors; nanocharacterization, nanomodification and nanostructuring of organic optoelectronic devices, nano-scale prototyping and machining using in-situ dual-beam applications, FIB based tomography and advanced TEM sample preparation techniques, Raman Spectroscopy and Wavelength-Dispersive Spectroscopy.

 

Professor Mustafa Urgen
İstanbul Technical University 

 Overview:Supercapacitors

Among various energy storage devices, supercapacitors have been considered as one of the most promising candidates. Supercapacitors have higher power density, longer cycle life, wider working temperature range, shorter charging times than batteries and may discharge very fast. They store energy using ion adsorption and/or fast surface redox reactions. This lecture will start with giving a historical perspective of capacitors especially emphasizing  their reversion from “electronic or electrical components” into their first function: energy storage devices. Present usage fields of these devices in different industry sectors will also be outlined in this part of the lecture. In the second part of the lecture working principles and classifications of supercapacitors will be given along with electrochemical methods used for the determination of their properties. In the last section, new developments for supercapacitor materials and strategies for increasing their performance will be outlined.

Mustafa URGEN is presently working in the  Metallurgical and Materials Engineering Department of Istanbul Technical University and leading the “Surface Technologies” group. He has received his bachelors, masters and doctoral degrees from Istanbul Technical University. After finishing his PhD, he conducted post –doctoral studies at Max-Planck Institute, Institut für Metallwissenschaften, Stuttgart, Germany (1988-89). His current research  focuses on the hybrid deposition techniques, production and characterization of nano-composite structures, nano patterning of surfaces. He has also interest in alternative electrochemical methods for producing electroactive materials. He has more than 200  journal and conference publications and is  one of the authors of 4 issued and 3 pending patents.
