Three-day international technical training course on “Vacuum Applications in Applied Surface Science” kicked off at the COMSTECH Secretariat on Tuesday with a special emphasis on the use of vacuum technology for advancement. The course is being organized by the COMSTECH and Pakistan Vacuum Society (PVS) in collaboration with the International Union for Vacuum Science Technique and Applications. Director General, National Agency for Scientific Research and Innovation, Mauritania, Prof. Dr. Ahmed Elmouna, as the chief guest of the inaugural session, said that this course is a demonstration of the dedication and commitment of the COMSTECH and PVS that we witnessed a wonderful gathering here to explore the fascinating world of vacuum science and technology and its applications in surface science. Prof. Elmouna said that vacuum science has played a paramount role in advancing the understanding of the physical and chemical properties of surfaces and enabled us to explore the properties of materials at the atomic and molecular levels, leading to groundbreaking discoveries and innovations that have transformed the world. Coordinator General COMSTECH, Prof. Dr. M. Iqbal Choudhary said that vacuum science and technology have played a central role in the development of science, technology and industry throughout the world. The applications of vacuum technology, in the modern industrial and Research and Development world are countless.
