Electrospun sodium titanate speeds up the purification of nuclear waste water
Electrospun sodium titanate speeds up the purification of water based on selective ion exchange – effectively extracts radio-active strontium
With the help of this new method, waste water can be treated faster than before, and the environmentally positive aspect is that the process leaves less solid radio-active waste.
The properties of electrospun sodium titanate are equal to those of commercially produced ion-exchange materials.
“The advantages of electrospun materials are due to the kinetics, i.e. reaction speed, of ion exchange,” says Risto Koivula, a scientist in the research group Ion Exchange for Nuclear Waste Treatment and for Recycling at the Department of Chemistry at the University of Helsinki.

Everyone knows about the “this is not a place of honor” nuclear waste site warning. But the one I find really endearing is the other idea to breed cats that change color or glow as a warning (from Wikipedia):
- French author Françoise Bastide and the Italian semiotician Paolo Fabbri proposed the breeding of so-called "radiation cats" or "ray cats". Cats have a long history of cohabitation with humans, and this approach assumes that their domestication will continue indefinitely. These radiation cats would change significantly in color when they came near radioactive emissions and serve as living indicators of danger. In order to transport the message, the importance of the cats would need to be set in the collective awareness through fairy tales and myths. Those fairy tales and myths in turn could be transmitted through poetry, music and painting. The story of this original project was depicted in the 2016 short documentary “The Ray Cat Solution”.
Can’t stop thinking about the cultural integration just being
“Row, row, row your boat /
Gently down the stream /
Merrily, merrily, merrily /
Its bad when cats turn green!”
“Get rid of it that way.” As though the moon were a problem we’d been trying to solve for years.
