Why are some aluminum atoms so dense?
In a recent study, scientists found that some of the strongest aluminum atoms in the world are found in regions of the earth where air and water meet, which can explain why they tend to cluster together.
The research also suggests that these clusters are more stable than the typical clusters found in other environments, like those in our atmosphere.
“This is a surprising result, and suggests that some aluminum ions might be more stable and may be more active in the presence of water,” lead author and chemistry professor at Harvard University, Jens Janssen, told Business Insider.
“This could have important implications for understanding the mechanisms underlying the chemistry of water and aluminum ions, and their role in Earth’s atmosphere.”
Scientists originally identified these clusters in 2007, when they measured the ratio of the density of aluminum ions at the surface of the planet.
In 2011, they determined that the density also varies with latitude, and that the highest density in the northern hemisphere is the lowest in the southern hemisphere.
In 2012, researchers reported that the same phenomenon was observed in the Antarctic.
The new study found that the dense clusters found along the Antarctic coast are not isolated from the rest of the world.
They found that while the average density of the ions in Antarctica was around 4.6 grams per cubic meter, the average concentration was 2.7 grams per square meter.
That’s more than twice as high as the global average, which is around 0.8 grams per sq. meter.
The study, published in Science Advances, also found that these regions of high density are the ones with the lowest concentrations of sulfate ions, which are thought to form as sulfate-rich materials that trap sunlight.
The scientists say the sulfate concentration is responsible for the silicate clusters, which occur near the equator and tend to be more common in colder areas.
“These silicate-rich areas have a different chemistry to the sulfates in the mantle and crust, and have higher concentrations of oxygen,” Janssens said.
“That’s why these regions have more sulfate and less oxygen.”
The researchers used X-ray diffraction to measure the density in each of the 13 regions they studied.
The results showed that the densities in the Arctic and Antarctic were the highest and lowest in these regions.
The densities were also higher in the Northern Hemisphere than the Southern Hemisphere.
The research also found these clusters to be much more stable in the extreme cold environments found in Antarctica than the rest, suggesting that they could hold more water.
The researchers also found a connection between the density and the amount of aluminum in the water.
In fact, if the denser the water is, the higher the aluminum concentration.
The researchers believe that aluminum is more stable when water is low in magnesium than when it is high in magnesium.
The findings suggest that this is why the high-density regions of Antarctica are more saline than the other regions, because the higher levels of aluminum cause more silicate ions to cluster there.
