Demystifying signal processing techniques to extract task …

In theory, we can never extract the frequency information whose period is longer than the time window . For example, the lowest frequency is 5 Hz if the window is 200 ms. To achieve a better SNR, we would want the window to contain two or three periods of certain frequency information, which further limits the lowest frequency we extract.

Lithium recovery from brines

Lithium has various uses, but its abundance in nature is only 0.0018%. The use of lithium on ceramics enriched with Li 6 is up to 15% for use in the production of tritium. In addition, enriched Li 6 is very expensive, what is commensurate with the value of gold. Consequently, it is necessary to extract and recycle lithium from the waste of solid breeding materials.
