Hofmeister Specific Ion Effects, Buffer Effects, and the Theory of Colloidal Interactions

22 August 2023

📢 Save the date! We're excited to announce the upcoming seminar on 24-08-2023 (this Thursday) with Dr. Drew Parsons from the Department of Chemical and Geological Sciences at the Università degli Studi di Cagliari, Italy, and Murdoch University, Western Australia. 🌍


 🗓️ Date: 24-08-2023

🕙 Time: 10:00 - 11:30 AM

🏢 Venue: Ensemble3 Open Space (Pietro 1), Building 8, Łukasiewicz - Institute of Microelectronics and Photonics


🎤 Join us for an insightful session on "Hofmeister Specific Ion Effects, Buffer Effects, and the Theory of Colloidal Interactions." 🧪


📚 Short Abstract:Dr. Parsons will delve into the impact of Casimir-Polder interactions on biochemical reactions. He will explore the role of dispersion forces in shaping complex geometries that could have implications for bioinspired photonic materials.


📚 Longer Abstract:Specific ion effects perturb the expected behaviour of a system in salt solutions. These deviations are often described using the Hofmeister series, which quantifies the strength of the deviation based on the cation or anion in the salt. Hofmeister effects play a role in pharmaceutical and industrial scenarios where consistent pH values using buffer solutions are essential. Interestingly, buffers themselves exhibit unique ion effects known as buffer-specific effects. Our experimental results underline. Our experimental findings underscore the significance of these buffer-specific effects in various interactions, from inorganic porous silica to lysozyme protein interactions and DNA melting.Join us to learn more about this fascinating field of study as we explore the modifications to the Poisson-Boltzmann model and its implications for ion-specific and buffer-specific effects. 🧪
