A New Form of Ice with Liquid-Like Structure Discovered
The researchers have discovered a new type of ice that has a molecular structure similar to that of liquid water, despite being a solid.
The new ice is named medium-density amorphous ice (MDA) and has a density similar to liquid water. Previously, only two types of amorphous ice have been known, high-density and low-density amorphous ice.
The findings were published in Science and were presented by Christoph Salzmann, a materials scientist at University College London. According to Salzmann, 20 crystalline forms of ice have been known, but only two types of amorphous ice have been discovered so far.
A new type of ice form, which has a molecular structure similar to that of liquid water, has been discovered by researchers. The density of this new form, called medium-density amorphous ice (MDA), is also similar to liquid water. The discovery was published in Science and the results show that MDA exists in the previously thought density gap between the two main types of amorphous ice.
The team found MDA by using a method called ball milling, which involves shaking ordinary water ice in a jar with steel balls cooled to -376 degrees Fahrenheit (-200 Celsius). The ice was then pulverized into a powder-like substance, which looked like white powder but had the molecular composition of liquid water.
The lead researcher, Alexander Rosu-Finsen, explained that they destroyed the crystal structure of the ice through ball milling and ended up with an entirely new kind of substance. The new substance has some remarkable properties, he said.
The discovery of MDA, a new form of ice with a molecular structure resembling liquid water and a density within the gap between high-density and low-density amorphous ice, has far-reaching consequences for our understanding of liquid water and its anomalies.
The discovery of MDA was made by shaking ordinary water ice in a jar with steel balls at a temperature of -376°F and breaking up its molecules using mechanical forces, resulting in a white powdery solid with the molecular composition of liquid water.
The discovery of MDA requires scientists to reevaluate the behavior of water and water ice in extreme conditions and has potential geophysical implications for ice on the surfaces of frozen moons like Europa.
The researchers believe that amorphous ice, including MDA, is the most abundant form of water in the universe, and the race is now on to determine how much of it is MDA.
The recent discovery of medium-density amorphous ice (MDA) is not the first study of its kind, as scientists have been exploring the nature of ice for some time.
In the past, another team of physicists created a new form of ice by compressing water ice into a tetragonal crystal structure, called Ice-VII, which is different from the traditional hexagonal symmetry of water ice known as Ice-I.
The discovery of MDA, which is a unique and intriguing form of ice, is expected to spur further research into how water manifests in different forms across the universe. This would be a positive outcome, as it could lead to a better understanding of the properties of water and its different forms.
