Shima Ghanavati Nasab received her B.Sc. in applied chemistry in 2011 and her M.Sc. in analytical chemistry in 2014 from Payam Noor University. She joined the Shahrekord University as a Ph.D. student in the field of analytical chemistry and chemometrics and completed her research in 2018. During her research, she worked on pollutants removal and application of chemometric methods for the optimization. In 2017, she worked with Prof. Federico Marini group in Italy for nine months as a visiting Ph.D. student and finished two projects in QSPR in Lubricants and Classification of Honey samples. She has participated in Chemometrics school in Copenhagen university for two months under the supervision of sophisticated teachers in the field of chemometrics. She was a Talented student in M.Sc. and also introduced as a Top researcher in her Ph.D. period Mehdi Javaheran Yazd received his Bachelor’s degree in mechanical engineering in 2008 with a research on heat treatment and HVOF from the IAU. He holds short courses in the science of materials and properties of metals. In 2019, he obtained a Master’s degree in mechanical engineering with an energy conversion trend from the IAU. Since 2016, he is a member of the Young Researchers and Elite Club of the IAU. He began his specialty in the energy field in 2009 and continued his research in the field of steam power plants. Since 2013 he has been focusing on energy optimization in industries, power plants, and buildings, and has followed energy modeling and exergy analysis. Abolfazl Semnani received his B.Sc. in chemistry from the University of Isfahan in 1989. In 1991, he earned an M.Sc. and in 1995, got his Ph.D. in analytical chemistry from Shiraz University. His research interests are the spectrophotometric and electrochemical study of crown ethers, conservation of cultural& historical works, environmental chemistry, industrial lubricants, and chemometrics. He has received awards as a distinguished researcher from Shahrekord University in 1999, 2001 ,2005, 2006, and 2008. He invented the process of synthesis of an additive for preparation of multigrade base oils from mineral base oils (Registration no. 388080661 in Iran). He has written more than 100 ISI papers. Homa Kahkesh graduated with a B.Sc. from Payam NoorUniversity of Khorramshahr in 2012. She earned an M.Sc. degree in analytical chemistry from Payam Noor University of Esfahan in 2014. She was admitted to the Shahid ChamranUniversity of Ahvaz as a Ph.D. student in analytical chemistry in 2018. After receiving an M.Sc. degree, she started to teach at the university. She also cooperated in writing some papers about the removal and corrosion field under the supervision of Professor Semnani. Her current interests are electrochemistry, corrosion, spectroscopy, and chemometrics. Navid Rabiee graduated with an M.Sc. degree in inorganic chemistry from Shahid Beheshti University, Tehran, Iran, in2018. During his M.Sc. research, he worked on porphyrin-based biosensors and the application of porphyrins and cobalt complexes on Dye-Sensitized Solar Cells (DSSC) under the supervision of Prof. Nasser Safari. At the same time, he was focused on drug delivery systems based on biocompatible and biodegradable polymers associated with different types of sensitizers, especially porphyrins, under the supervision of Prof. Mohammad Rabiee at Amirkabir University of Technology, Tehran, Iran. In 2017, he joined ANNRG to collaborate with Prof. Mahdi Karimi's Research Lab at Iran University of MedicalScience, Tehran, Iran, in association with Prof. Michael R. Hamblin from Harvard Medical University, Boston, MA, working on smart microcarriers/nanocarriers applied in therapeutic agent delivery systems employed for diagnosis and therapy of various diseases and disorders such as different cancers and malignancies, inflammations, infections, etc. Currently, he is a Ph.D. candidate in inorganic chemistry at Sharif University of Technology, Tehran, Iran, and working on different types of smart nanocarriers in collaboration with Amirkabir University of Technology and Iran University of Medical Sciences. Since2018, he has participated in a collaboration with the Global Burden of Disease (GBD) project at the University of Washington, Seattle, Washington, in association with the Institute for Health Metrics and Evaluation (IHME), and has worked on some brilliant projects that have been published in The Lancet, Nature, and other highly-cited journals. His work has resulted in the publication of over 40 peer-reviewed journal articles, 5 books, and 3 conference papers. Mohammad Rabiee, Ph.D., is an associate professor in the Biomedical Engineering Department at Amirkabir University of Technology, Tehran, Iran. His current research interests include smart drug delivery systems, tissue engineering, and biological sensors. He has published over 100 ISI papers and also over 70 international conference papers. In addition, he has been teaching and researching for 27 years at Amirkabir University of Technology, Tehran, Iran. Mojtaba Bagherzadeh, Ph.D., is a professor in the Department of Chemistry at Sharif University of Technology, Tehran, Iran. His current research interests include inorganic chemistry, inorganic catalysis, and bioinorganic chemistry. He has published over 100 ISI papers, with the H-Index of 31.
