“Frozen Smoke” Used for Protecting the Environment

Using a recent innovation discovered by chemists at the University of Debrecen, it is possible to remove toxic aqueous mercury pollution from the environment without endangering wildlife or other living organisms. The publication on special aerogels appeared in Chemosphere.

István Fábián and István Lázár began researching aerogels at the Department of Inorganic and Analytical Chemistry of the Faculty of Science and Technology of the University of Debrecen in 2005. These are the “least dense” cross-linking materials in the world, and their density can be as low as a few kilograms per cubic meter.

“Aerogels are porous solid materials with very light and thin geometrical structure, high specific surface area and low thermal conductivity, which makes them excellent for the purpose of insulation, as they are indeed often used in everyday practice. Due to their sparse structure, they can adsorb large amounts of fluid, and this is one feature that we have also used during the course of our research project,” said József Kalmár, the leader of the research group to hirek.unideb.hu.
