Research Group Plasma Physics Laboratory (PPL)

Dr. Henry J. Ramos is an internationally recognized scientist in the field of Plasma science. Dr. Ramos used plasma technology, a high-energy gas, in developing state-of-the-art yet comparatively inexpensive coating technology for cutting tools in metal, wood and plastic items in construction supplies, car and computer parts, and many others. His low-temperature coating technology can deposit either a gold luster titanium nitride or a diamond-like thin film on metal substrates like knives, scissors, and drill bits that extend the lifetime of a device three to five times.

Dr. Ramos established the Plasma Physics Laboratory at the National Institute of Physics - University of the Philippines-Diliman, where he was director from 1993 to 2000. The laboratory was used in the experiment and development of modest plasma systems to provide researchers and students practical knowledge and skills on such area.

Dr. Ramos published at least 16 scientific papers on the subject. He is currently the country’s representative to the Asia Africa Association for Plasma Training. He also serves as peer reviewer in a scientific journal, IEEE Transactions in Plasma Science.[1]
