Non fiction critical analysis
In the article Strange New State of Hydrogen Created the author Jesse Emspak explains how a new type of hydrogen was made. They have now found a new state of hydrogen. This new way is through crushing the hydrogen with very high pressure. The scientists who were a team of doctoral students at the University of Edinburgh in Scotland were able to solidify the hydrogen at room temperature (around 80 degrees). This is the first time people found a way to solidify hydrogen in such warm temperatures.
The author talks about shattering diamonds a little more and what happens when the pressure is turned up more. “To have been certain hydrogen took a metallic state (without a conductivity test), the team would have needed to reach even higher pressures, at least up to 400 to 450 gigapascals, the scientists said.
Those pressures might surpass the limits for diamond anvils, which can shatter,” Gigapascals is another way of measuring, the students used 384 gigapascals which is about 55 million pounds per square inch. The team plans to see how far the anvil diamonds will go before they shatter. There are other techniques besides the anvil diamonds do exist, but don’t tend to work well with hydrogen.
Being able to crush the hydrogen is what the team was really looking to do. “When the pressure hit the 325-gigapascal mark, or 47 million psi, the hydrogen became a solid, with the atoms forming layers that alternated between orderly and jumbled arrangements.” The team took it a step forward in reaching what I previously said 384 gigapascals. Liquid hydrogen is created quite easy to produce at cryogenic temperatures. Nobody yet has been able to cool the element enough for it to be solidified.
People have tried to make hydrogen into a metallic form but it isn’t completely proven that someone has done it. “In 2011, a team of scientists at the Max Planck Institute for Chemistry in Mainz, Germany, said they had created metallic hydrogen, but that claim later came under some fire from other scientists and was never fully confirmed.” The main student that conducted the experiment said that they came close to making metal but were not quite able to. even though solids and liquids are the most familiar but there are many other phases that appear under more extreme conditions.
Knowing more about hydrogen and how to make more different ways to use this. This new way to solidify hydrogen could help scientists discover more mysteries about space and even more things about our own planet. The author did a good explaining the team that did it, how they are trying to solve more topics, and what limitations might be set on what they try to accomplish. This topic has vast possibilities and might have a big impact on science.
