 Also, with my coworkers, we got a Canadian patent on decreasing the toxicity of asbestos by calering it with organic dyes. Yeah, could you tell me a bit more about that? Yes. Because that's also a very hot topic nowadays. This I consider my best work in this field. We had the help from a professor of biochemistry in the Faculty of Medicine at Laval. So we dyed the asbestos fibers with different organic dyes and sent it to him to test for their toxicity. And he found out that some dyes decrease the toxicity of asbestos greatly. And that's why we got a patent on that. But unfortunately, at that time, we couldn't get research funds to continue our work because at that time, all research funds were given to lawyers to defend the case of Canada in the United States against the environmental agency in the United States. And by the way, they won the case. But it was too late because after many years, the postdoctoral fellow in my group, he left and I retired. And that's why the project was not followed up. But we published many papers on this topic and we are satisfied that we got a patent. And unfortunately, the asbestos industry collapsed completely in Canada and all in the world. Although the solution was to, if the color of the asbestos could decrease its toxicity and coloring asbestos in water is not a problem because most of the asbestos is used to make asbestos cement. And they put asbestos in water to make the pipes of cement and this necessitates adding few coloring matters to the water and then it will not increase the technology too much. But as I said, the industry collapsed completely.
