How to Make Your Next Paper Scientifically Effective?

TenTips forScholarly Publishing

Abstract:Sharing scientific knowledge through publications is an integral part of research career. Since more and more organizations evaluate scientific productivity by scholarly publication rates, the impact of published work becomes an important issue. New researchers face the challenge of mastering the art of scientific publication to draw attention to their new scientific findings. The lecture will address following questions. What are common practices in publishing scientific work? What are common misconceptions? What are the key steps that are necessary to compose an effective paper?

Insight into the Operation of Perovskite Solar Cells

Abstract:With the emergence of highly efficient lead halide perovskites there is a need to understand the excited state behavior and charge separation events following photoexcitation. Mixed halide lead perovskites offer a useful strategy for continuous tuning of the semiconductor bandgap. For example, by varying the halide composition of methylammonium lead iodide/bromide (CH3NH3PbBrxI3-x(x=0 to 3)) it is possible to tune the bandgap between 1.55 eV and 2.43 eV. In addition to photovoltaic applications these mixed halide perovskites offer rich photophysical properties with lasing applications. The excited state characterization using emission and transient absorption spectroscopy has allowed us to probe the photoinduced processes. Of particular interest are mixed halide lead perovskites (e.g.,CH3NH3PbI3-xBrx) which offer flexibility of tuning bandgap. Interestingly, they also undergo phase segregation to create Iodine-rich and Bromide- rich regions when subjected to visible irradiation. This intriguing aspect of halide ion movement in these mixed halide films can be tracked from the changes in the photoluminescence and absorption spectra. The photovoltaic performance of perovskite solar cells with varying degree of halide treatment will also be discussed

Biography:Prashant V. Kamat is aRev. John A. Zahm, C.S.C., Professor of Science in the Department ofChemistry and Biochemistry and Radiation Laboratory at University of Notre Dame. He is also a Concurrent Professor in the Department of Chemical and Biomolecular Engineering. He earned his doctoral degree (1979) in Physical Chemistry from the Bombay University, and postdoctoral research at Boston University (1979-1981) and University of Texas at Austin (1981-1983). He joined Notre Dame in 1983. Professor Kamat has for nearly three decades worked to build bridges between physical chemistry and material science to develop advanced nanomaterials that promise cleaner and more efficient light energy conversion.

He has directed DOE funded solar photochemistry research for the past 30 years. In addition to large multidisciplinary interdepartmental and research center programs, he has actively worked with industry-sponsored research. He has served on many national panels on nanotechnology and energy conversion processes. He has published more than 450 scientific papers that have been well received by the scientific community (50000+ citations). Thomson-Reuters has featured him as one of the most cited researchers in 2014 and 2016.

He is currently serving as the Editor-in-Chief of ACS Energy Letters. He has also served as the deputy editor of theJournal of Physical Chemistry Letters. He is a member of the advisory board of several scientific journals (Research on Chemical Intermediates, Journal of Colloid & Interface Science, and Applied Electrochemistry). He was awarded Honda-Fujishima Lectureship award by the Japanese Photochemical Society in 2006, CRSI medal by the Chemical Research Society of India in 2011 and Langmuir lectureship award in 2013. He is a Fellow of the Electrochemical Society (ECS), American Chemical Society (ACS) American Association for the Advancement of Science (AAAS) and Pravasi fellow of the Indian National Science Academy.
