Dr. Someshwar Pola has been working as an Assistant Professor in the Department of Chemistry, University College of Science, Osmania University since 2018. He worked as an Assistant Professor in the Department of Chemistry, Nizam College, Osmania University from 2013 to 2017. He received his B.Sc. from Kakatiya University, M.Sc from P.G Center, Mirzapur, Osmania University, and Ph.D. in chemistry from Kakatiya University,

Warangal, Telangana State, India. Dr. Pola worked as a visiting faculty member at the Institute of Chemistry, Academic Sinica, Taipei, Taiwan for two months in 2017. He also worked as a Postdoctoral Fellow (PDF) at the Institute of Chemistry, Academic Sinica, Taipei, Taiwan from August 2008 to April 2012. During this period, he focused on the synthesis and characterization of organic functional materials towards single-crystal field-effect transistors. During the period of his doctoral research work (2002 to 2006), he developed various methodologies in inorganic and analytical chemistry. He also has industrial experience in medicinal research and development (AR&D), GVK Biosciences Pvt. Ltd., Hyderabad, India. Dr. Pola has published over 48 research papers in reputed international and national journals and has one book chapter to his credit. He has also presented research papers at 35 national and 25 international conferences. He has delivered guest/invited lectures in various colleges/conferences. He is a Life Member of the Society of Materials Chemistry (SMC), Materials Research Society of India (MRSI), Indian Science Congress Association (ISCA), India, and a member in the American Chemical Society (ACS). He is a reviewer for Elsevier, ACS, and RSC journals. He has 8 years of teaching and 20 years of research experience. His research focuses on supramolecular chemistry, solar cell device fabrication studies, organic field-effect transistors, photocatalysis of organic pollutants in the presence of titanates, perovskites and related semiconductor and metal-organic frameworks. Under his supervision, 6 postgraduate students have completed their dissertation work, 3 Ph.D. students have been awarded and 8 scholars are currently working for their Ph.D. degree. His research activities are supported by various funding agencies like NSC-Taiwan, UGC, DST and CSIR, New Delhi, India.

Neeraj Panwar, Ph.D., is presently a Senior Assistant Professor in the Department of Physics, Central University of Rajasthan India. He has postdoctoral research experience from the University of Puerto Rico, U.S.A. and the University of Aveiro, Portugal. He has had several research collaborations at the international and national levels. He has guided two Ph.D. theses and several master's and undergraduate students for their dissertation work. He

has published more than seventy international research papers. His areas of interest include magnetism and lead-free piezoelectric and electroceramic materials. He is also interested in practicing yoga.
