In a scientific project, #manganese was already mined in the #deep sea in 1989. As late as 2015, inspections revealed damage to the ecosystem in the entire area.

But the greed for #profit of the #economy has no scruples to lie to us and the politics. In addition, to build a backdrop of fear that otherwise we can not cope with the #Energy transition. But their exploitation is responsible for the mess we are in.

" It estimates there is vast mineral wealth embedded in around 7bn tonnes of #PolymetallicNodules sitting on the #seabed within in its territorial waters. Forming over millions of years, the typically black, round potato-sized nodules are rich in #cobalt, #copper, #nickel, and #manganese. "

Manganese: atomic number: 25; weight: 54.938044; Transition metal; discovery: 1770-1774—Torbern Bergman, Scheele, Johan Gottlieb Gahn #Poetry #Science #History #Manganese (https://sharpgiving.com/thebookofscience/items/e025.html)

One of the best seasonal vegetables to introduce to your children as early as possible in their lives - well, as soon as they have teeth, as teeth are needed to strip the luscious flesh from the tough central stem.
Nutritionally rich in #potassium, #manganese, #calcium, #silicon, #boron, #iodine, and #vitC, this sea-baptised plant can be lightly boiled & served with butter or pickled for an intriguingly tangy treat.
**** Who can guess which plant I'm describing? ****

This morning in #Mexico many #Android phones will be confusing people by showing the wrong #time. We no longer have #DST, but updating the #tzdata timezone database on most older devices is almost impossible.

Don't worry, just buy a new device. It's easy, Just throw all that silly old #lithium, #manganese, #tellurium, #tungsten and #cobalt in the landfill.
And all for a locked #bootloader.

An example of 💩 gle and the phone manufacturing industry being #evil.

Hi @DNPFred
In grad school I worked on heme proteins using #paramagnetic #NMR and #NRVS. Then I shifted to #XRayCrystallography, using #EPR #UVVis and #EDX on #crystals when a postdoc. My research group works on #NonHemeIron #enzymes, & #heme, #copper & #manganese #metalloproteins. Really interested in combining #spectroscopy on #protein #crystals to examine #structure #function relationships.

@Timmy No need to discuss #alumium or #manganese (if you're not familiar with the latter, it's the most common alloying agent in #steel - it's everywhere).

#Cobalt usage has been steadily declining (a couple decades ago it was as high a % as the #nickel), and there's hope it will be entirely eliminated in the coming years - but as for now it's still in use. Cobalt is the most expensive of the metals (offset by its low percentage), which is a major factor driving the work to eliminate it.

@Timmy As the #LFP patents have been expiring, and it uses no nickel, its use has been increasing dramatically (despite giving lower range, and some other disadvantages).

For longer range, one uses, as mentioned, the nickel-based chemistries. These #cathodes are mixed metal oxides, usually in the ballpark of 80% (or higher) nickel, 10% (or lower) #cobalt, and 10% (or lower) #alumium or #manganese.

The #protein #BICAT3 is one of the most important #manganese distributors in #plants. If defective, this can have devastating effects on a plant's growth; its leaves grow significantly smaller and it produces fewer seeds than usual.
