the cell wouldn't work; the field forms when the N-type and P-type silicon come into contact. Suddenly, the free electrons on the N side see all the openings on the P side, and there's a mad rush
Both elements have multiple oxidation states, but the same biological pathway does not reach some of these states. For instance, elemental sulfur (S0) can be formed by (partial) sulfide bio-oxidation but not by sulfate bio-reduction, whereas elemental selenium (Se0) can be formed by selenite...
Sulfur itself is a critical plant nutrient that has been written off as something toxic to worry about in the soil science field. While in previous decades not worrying about sulfur may have been fine, things have changed. This is due to more efficacious environmental laws in the US and the...
The results show that: (1) environmental technology standards can have “win–win” effects, i.e., environmental technology standards can simultaneously improve the environmental performance and the economic performance; (2) the dynamic effects of environmental technology standards are proven in the ...
the interesting part begins when you put them together. That's because without an electric field, the cell wouldn't work; the field forms when the N-type and P-type silicon come into contact. Suddenly, the free electrons on the N side see all the openings on the P side, and there's...
Since acid rain can kill aquatic animals, weaken trees and dissolve stone, it seems like it could also scald or burn humans. But it doesn't affect people in the same way as it does fish or plants. Acid rain feels the same as regular rain -- it's even safe to swim in an acidic ...
(See How does a GFCI outlet work? for details). What happens to a hair dryer if you drop it in water when it's not plugged in? You don't run the risk of electrocution, since there's no source of current, but you can certainly damage the hair dryer if all of its components get...

Interestingly, the radiation actually does break the microbe's DNA into pieces. But in many cases, the DNA can reassemble and work normally again. It accomplishes this by shedding broken parts of DNA, using a special enzyme to attach good DNA to other still-healthy pieces of DNA, and then...
