students will deepen their understanding of the nitrogen cycle and its role in the ecosystem as a vital nutrient for plant growth. At the end of this lesson, students will be able to identify the physical effects of nitrogen (excess and lack of nitrogen) in soils on plant growth. Students ...
This I have been able to do through the use of certain oscillators that I have made and of which doctors of science have said are the most powerful devices known to science today. With the use of these oscillators and the oscillating effect of condensers which I have sometimes explained in ...
Raised peatlands, or bogs, are gently mounded landforms that are composed entirely of organic matter1–4 and store the most carbon per area of any terrestrial ecosystem5. The shapes of bogs are critically important because their domed morphology4,6,7 acc

Based on the findings, nitrogen compounds can, depending on the circumstances, either slow down or accelerate the growth of aerosol particles. This means that reducing sulfur dioxide is not on its own enough to prevent the smog problem seen in large cities. Instead, a comprehensive unde...

A chiral derivatizing agent (CDA) with the aldehyde function has been widely used in discriminating chiral amines because of the easy formation of imines under mild conditions. There is a preference for the use of cyclic aldehydes as a CDA since their lower conformational flexibility favors the ...
Heterogeneous catalysts are chemical catalysts whose physical phase is different from the physical phase of the reactants. Learn about heterogeneous catalysis here.
