Over the summer of 2011, Sadza, who’s currently in the board of study association Japie, spent three months in the lab of prof. Joanna Aizenberg through intercession of his supervisor dr. Nico Sommersdijk. In Boston he assisted Dutch postdoc Wim Noorduin with experiments. They mixed sodium silicate and barium chloride solutions in a beaker and then exposed them to CO2 from the air, which led to the forming of flower-shaped crystals measuring no more than several dozen micrometers. Noorduin colored the images generated with an electron microscope, making them look very similar to flowerbeds.
