Prof. Davor Kovacevic
I am really sorry to hear the sad news about Prof. Kralchevsky. I am sure that his scientific and personal achievements will be remembered not only at your University and in Bulgaria, but also in European colloid community generally. ECIS meetings and other events without him won’t be the same any more, we have lost an outstanding colleague and friend. Please pass my respect and condolances to his family and friends.
