Naresh C Osti is a Neutron Scattering Scientist at Oak Ridge National Laboratory (ORNL), working as an R&D Staff/Beamline Scientist at the Backscattering Silicon Spectrometer (BASIS) within the Neutron Scattering Division. He is part of the Chemical Spectroscopy Group under the Spectroscopy Section of the Neutron Scattering Division, which falls under the broader Neutron Sciences Directorate at ORNL. Dr. Osti received his MS in Physical Chemistry from Tribhuvan University, Kathmandu, Nepal, and his PhD in Chemistry from Clemson University, Clemson, SC, USA, in 2014. After completing his PhD, he joined ORNL as a postdoctoral researcher, working under the supervision of Dr. Eugene Mamontov until 2017, when he transitioned to his current R&D Staff position. His research focuses on exploring the structure and dynamics of energy-related materials (both hard and soft) to understand their structure-property relationships for real-world applications, especially in the areas of nano-confined fluids, polymers, and polymer nanocomposites. His work heavily utilizes neutron scattering techniques to investigate molecular dynamics and structural properties of advanced materials. Dr. Osti's recent publications demonstrate expertise across multiple domains including solid-state battery materials, polymer nanocomposites, ion transport phenomena, and advanced neutron scattering methodologies. His work spans fundamental understanding of molecular dynamics to practical applications in energy storage technologies.

Saša Marcinek is a Postdoctoral Fellow at the Rudjer Boskovic Institute in Zagreb, Croatia, working within the Institute for Marine and Environmental Research at the Laboratory for physical chemistry of traces. With a doctoral degree completed in 2021 from the Faculty of Science and Mathematics in Zagreb, Dr. Marcinek has established a research career focused on marine and environmental chemistry, particularly in the area of trace metal speciation and dissolved organic matter dynamics in estuarine environments. Dr. Marcinek's research primarily centers on the biogeochemical processes occurring in estuarine systems, with a particular focus on the Krka River estuary in Croatia. Their work encompasses several key areas: Development and improvement of voltammetric methodologies for trace metal speciation Analysis of dissolved organic matter dynamics using spectroscopic techniques Investigation of metal-organic interactions in natural waters Development of software tools for environmental data analysis Assessment of anthropogenic impacts on coastal ecosystems Recent publications demonstrate a strong focus on methodological advancements in analytical chemistry applied to environmental problems. Dr. Marcinek has contributed significantly to the development of new tools like TreatEEM for fluorescence analysis and ASFit for UV-Vis spectroscopy of dissolved organic matter. Their work often involves international collaborations, particularly with researchers studying trace metal behavior in estuarine and marine environments. A notable trend in their recent work is the examination of platinum group elements as emerging contaminants in coastal waters, reflecting growing concerns about anthropogenic impacts on marine ecosystems. Dr. Marcinek has been active in the scientific community, presenting research at numerous international conferences including the International Estuarine Biogeochemistry Symposium, Goldschmidt Conference, and ASLO Aquatic Sciences Meeting. Their work has appeared in respected journals such as Marine Chemistry, Analytica Chimica Acta, and Water.
