Preface

The 5th International Conference on Energy Engineering and Smart Materials (ICEESM-2020) was held during April 15-17, 2020. This year, our annual Conference was planned to be held in beautiful and sunny Barcelona, but, unfortunately, due to the spread of the COVID-19 virus around the world, we have to curry on our presentations online. The conference programme included the invited and oral presentations from scientists working in similar areas to establish platforms for collaborative research projects. The time for each invited speaker was 45 minutes, while for authors was 15 minutes each. All keynote, parallel sessions, discussions and other activities were offered in a streaming online. The conference covered the recent trends and achievements in the fields of energy engineering, environmentally friendly technologies and smart nanomaterials. This year we have around twenty participants from Ireland, Spain, Russia, Bulgaria, Romania, China, Jordan, India, Brazil and other countries, whom we wish fruitful discussions. ICEESM2020 created a customized online platform that was a virtual environment where the attendees could present the papers and participate in all the sessions that were organized in a full immersive experience. We hope that you and your families are keeping well and safe. We would also like to thank all of you for making this year ICEESM Conference possible, despite this very difficult time for all of us.
