Academician Yuriy Volodimirovich Naidich - outstanding internationally recognized Ukrainian scientist - has passed away. His contribution into the studies of capillary phenomena in metallic melts is well known. Academician Naidich pioneered many important topics of modern material science. He has proposed several approaches to control wettability of different types of materials by liquid metals: covalent ceramics, ionic crystals, and refractory metals. Diamonds, oxides, fluorides, carbides, borides, nitrides, perovskites are among them. More than 1500 contact systems were studied under the supervision of Yuriy Volodimirovich, many of them for a first time. On the basis of extensive experimental results Academician Naidich has formulated general principles of wettability by liquid metals based on the thermodynamic approach and recommendations for effective joining of materials of different nature
