Mr. Engineer Kambiz Javanroui with a master's degree; A graduate of Khajeh Nasir Toosi University of Technology (KNTU); The trend is nanotechnology-nanomaterials and his focus is on the coating of bio-alloys such as steel 304 by pvd method as a cost-effective alternative to Tc4 alloy in the field of nano-biotechnology. In recent years, he worked with Dr. Hamid Khorsand (member of the scientific faculty of Khajeh Nasiruddin Tousi University), Dr. Sara Khamse (member of the scientific faculty of Iran Color Research Institute) and Mr. Dr. Bahram Ramzanzadeh Karati (member of the scientific faculty of Iran Color Research Institute) in the field of Niobium-Carbon B coatings. Figure: (a-c) Nb deposited on the surface of 304 stainless steel deposited by reactive sputtering method have closely cooperated. His favorite direction is medical engineering and nanobiotechnology, memory alloys and 3D printing.
