The Journal of Materials Science publishes reviews, full-length papers, and short Communications recording original research results on, or techniques for studying the relationship between structure, properties, and uses of materials. The subjects are seen from international and interdisciplinary perspectives covering areas including metals, ceramics, glasses, polymers, electrical materials, composite materials, fibers, nanostructured materials, nanocomposites, and biological and biomedical materials. The Journal of Materials Science is now firmly established as the leading source of primary communication for scientists investigating the structure and properties of all engineering materials

The Journals reports principally the achievements of materials science and engineering all over the world, putting the stress on the original research papers, review articles invited by editor, letters, research notes with novelty as well as brief of scientific achievement, covering a broad spectrum of materials science and technology, encompassing:

• metallic materials 
• inorganic nonmetallic materials 
• composite materials




Rajapakse Mudiyanselage Gamini

Senior Professor


I have 32 years of continuous service at the Department of Chemistry, where I taught 26 years (excluding 5 years of study leave from 1985 to 1991).  My specialty is in the broad areas of Physical Chemistry and Nanotechnology. I have taught almost all course units in Physical Chemistry in different years, but my main teaching modules are Basic Electrochemistry, Advanced Electrochemistry, Chemical Kinetics, Catalysis, Basic Polymer Chemistry, Advanced Polymer Chemistry, and Industrial Chemistry: Elementary Chemical Engineering, Chemical Technology, Physical Chemistry Laboratory and Advanced Physical Chemistry Laboratory. Depending on the need, which has arisen in some academic years, I have taught courses such as Chemical Thermodynamics, Quantum Mechanics, Advanced Materials and Devices and Molecular Symmetry. I have supervised at least two final year research projects in each academic year and three final year projects in most of the years. These research studies have contributed to some publications in indexed journals, peer-reviewed local journals and communications at various scientific forums such as the Sri Lanka Association for the Advancement of Science (SLAAS), Institute of Chemistry (Ceylon) (I. Chem.), the Peradeniya University Research Sessions (PURSE) and International Conferences in Nnotechnology. These projects were on various disciplines such as Electrochemistry, Electronically Conducting Polymers, Clay-Polymer Nanocomposites, Hydroxyapatite Coatings on Stainless Steel Prostheses for Orthopaedic Applications, Value Addition to Sri Lankan Natural Resources, Nanoscience and Nanotechnology, Dye-sensitized Solar Cells, Advanced Textile Materials such as Textiles with Antimicrobial, Self-cleaning and Antistatic Properties, Anticorrosive Nanocomposite Coatings and Targeted Drug Delivery using Nanomterials

University Education (Postgraduate Degrees)

Ph. D. and D. I. C. in Photoelectrochemistry of Colloidal Semiconductors

Imperial College of Science, Technology and Medicine, University of London, United Kingdom (1985- 1988)

I won the Overseas Student’s Fee Support Scheme Award and a Unilever Bursary (1985-1988) to read for Ph.D. and D.I.C. degrees at the Department of Chemistry, Imperial College of Science, Technology and Medicine, University of London, United Kingdom. I was selected, from the entire student community of the Imperial College, to present the Student Research Paper at the Imperial College Centenary Symposium, which was held in 1987, and the presentation was based on “Photoelectrochemistry of Colloidal Semiconductors”. The only other presentation was by a Senior Invited Lecturer, Nobel Laureate Professor Rudolph Marcus.


ii.         University Education (Undergraduate Degree)

B. Sc. Special Degree in Chemistry with Pure Mathematics as the Subsidiary Subject

University of Peradeniya, Peradeniya, Sri Lanka

First Class (Honours) Degree (1979-1983)

The “Jathika Navodaya” National Scholarship awarded in 1973 was continued until the completion of the First Degree in 1983, as the University Education was continued consecutively from the College Education through the University Selection from the First Attempt of the G.C.E. Advanced Level National Examination. Based on the Best Performance at each year-end examinations held in 1980, 1981 and 1982, I was awarded the Hayley’s Studentship, which is awarded to the Best Performer at year-end examinations of B.Sc. Special Degree in Chemistry, in the three consecutive years.



iii.        Secondary School: From Grade 9 to Grade 12:

Mo/Bibile Central College, Bibile, Sri Lanka (1974-1978) as a “Jathika Navodaya” National Scholar

I have successfully completed the GCE Ordinary Level National Examination in Science Stream held in December 1975 and the GCE Advanced Level National Examination in Physical Science Stream held in April 1978.


iv.        Junior School: From Grade 1 to Grade 8:

Am/Gonagala Vidyalaya, Ampara (1966 – 1973)

I have passed the “Jathika Navodaya” National Examination held in 1972 (Grade 7) and won the “Jathika Navodaya” Scholarship in 1973 to continue studies in a Central College (Mo/Bibile Central College) from Grade 9 (1974 – 1978).


  1. Presidential Awards-2017 

6 Certificates for Indexed Publications.

  1. NSF SUSRED Award 2016 Three awards for Ph.D. supervisions.



            This is the most prestigious award a Sri Lankan Scientist can obtain once in the lifetime. This is the most competitive Award that is awarded to the researcher who has excelled in a given broad discipline. I was awarded this most prestigious award in the year 2014.



This is an award given to supervisors of M.Phil. projects completed within three years of registration and/or Ph.D. projects completed within four years of registration in a Sri Lankan Postgraduate Institute. This is a novel award scheme introduced in 2011 to encourage university academics and researchers to produce postgraduate degrees within Sri Lanka. For the award in 2014 the RAs should have been graduated in the year 2013 with publications in indexed journals. We (and Dr. Sanath Rajapakse) were given this award for the M.Phil. Degree we produced in the area of Intelligent Textiles in 2013.



          I won the Presidential Awards for my publications in indexed journals in the years 2010, 2011 and 2012.
