I enjoyed the conference and city of Rome. The conference involves wide variety of topics with many especially companies. It was exciting to me. I hope WCSM-2022 will be successful one.

Thank you for the wonderful conference which you and your team had organized in Osaka Japan. The talks were of really high quality and the opportunity to network amongst the participants was very beneficial.

----Dr. Brando Okolo, Germany

Thank you very much for having given me the chance to attend the high quality conference. Frankly, your organization is quite good which is above the level of most international conferences which I have attended so far. One suggestion is that in the future, it is better not to include most activities on Saturday and Sunday since the western men think the weekends belongs to personal free time.

It was a beautiful conference, very well organized and managed! I really have only words of appreciation! It was a very distinguished group of personalities and I am most honored to have been selected to be a part of. Thanks to you, I also had the extraordinary opportunity to visit Japan!

----Dr. Ana Maria Dabija, Romania

It was a real pleasure for me to participate in WCSM. It was my first visit to Japan, and I was very impressed by this country. Congress was organized very well. Thank you. I look forward to attending your future meeting in Rome.

----Dr. Sergey Nikitenko, France

Thank you for your kind email. It was a pleasure to be invited to your congress and really a great honour attend it with so such learned scientists. Actually I don't think you need my suggestions because everything went well. I am so happy you had chosen Italy for the next congress.

Italy

I really enjoyed very much this conference and all of the interesting topics included in the program. Thank you for the expert organisation of the event.

---Dr. Rita Skoda-F?ldes, Hungary

I would like to thank you again for the excellent conference. Everything was organized exceptionally well. Thank you.

I look forward to attending your future conferences. Please keep me posted.

---Dr. Reza Abbaschian, USA

I would like to thank you for your kind email. In my humble opinion, the conference was very organized. The only suggestion I would provide is that the speakers to have a portable microphone. That will help projecting their voice all the time even if they are explaining things on the screen.

We enjoyed the BKK conference very much. It was one of the most well-organized conferences which we had attended. This year the poster session was improved compared with that in the Singapore conference. Although we found some very interseting posters, we could not contact and discuss with the authors.

--- Dr. Hitoshi Kunoh, Japan

It was a pleasure attending to Smart Materials 2016, to visit Singapore and to be with my family. I really enjoyed it.

Regarding the congress, I enjoyed it very much, in special the session of my communication, and I learnt a lot. I only have to point the strong air conditioning. The room temperature was too low. Once I had to go outside to become warm! But it seems that is usual in Singapore.
