It was my great pleasure to meet Prof. Dr. Arben Merkoçi. Thanks for the nice organization. So happy to see Prof. Dr. Arzum Erdem Gürsan and her students. We attended the conference with my dear colleague Prof. Dr. Ayşegül Ülkü Metin and our Ph. D.s Rabia and Deniz; we also combined family visits. Special thanks to my dear brother Uğur Horzum for his hospitality.
