In May, 2013, Prof. Dongfeng Diao, director of INSE, participated in the 41^th International Conference on Metallurgical Coatings and Thin Films, which was held at San Diego. He gave three speeches titled “The effects of electron irradiation conditions on the formation of embedded graphene sheets during carbon film deposition in ECR plasma”, “Super Smooth Nano-Structured Carbon Films with Cross-linked Graphitic Sheets Induced by ECR Ion Irradiation”, ”Effect of ECR Carbon Film on Demagnetization Behavior of the Magnetic Recording Disk Under Sliding Contact”, and played a positive role in building an international research platform for nanosurface science and engineering as well as exploring the horizontal in researching area.
