From Monday May 15 to Friday May 27, the CEDENNA exhibition "Images of the Nanomundo" will be installed on the esplanade of the Bellas Artes Metro Station for the public of all ages to visit and discover, through playful and beautiful images, the amazing world of nanoscience and nanotechnology.
The exhibition generated a lot of interest during its stay at the Planetarium, an opportunity in which children and adults had an approach to nanoparticles from a playful perspective that aroused their curiosity and interest in this science that is so present in everyday life through developments technologies that contribute to offering solutions in the fields of health, environment, agriculture, medicine, food packaging, among others.
"Behind this beauty that exists in the nanouniverse there are many practical things, since each of these particles has a specific use, for example to remove arsenic from water, to improve the quality of food packaging, to absorb oxygen and to that food does not oxidize and lasts longer, in a mining sensor or to detect pathogens in food", says the director of CEDENNA, Dr. Dora Altbir, National Prize for Exact Sciences 2019.
"We want to show that this world is tremendously useful and important for development, but also infinitely beautiful," he highlights.
Each of the 12 photographs considered in the sample were captured by CEDENNA researchers and students, through various techniques and electron microscopy. Thus, for example, a spring butterfly that flies among pollen grains turns out to be a porous hydrogel containing cellulose nanofibrils used for the remediation of colored water.
A beautiful pink jellyfish between apparent underwater rocks is not such. It is titanium dioxide (TiO2) which in its most common phase is known as rutile, with interesting optical properties described for centuries. Another photograph shows an aggregate of vanadium oxide tubes in different oxidations (V(5+) and V(4+)). The resemblance to a coral is striking.
Each image is accompanied by a scientific description that shows what is really behind each photograph.
After a tour of some educational and cultural centers in the Metropolitan Region, the exhibition will begin its itinerary from Arica to Punta Arenas.
