Novel Technique to Allows Scientists to Observe How Atoms Move in Liquid.
The team, led by scientists from the National Graphene Institute , used stacks of 2D materials, such as graphene, to trap liquid to truly comprehend how the existence of liquid alters the behavior of the solid. Their findings were published in the journal Nano Letters.
When a liquid and a solid are in close proximity to one another, both substances adapt to the other’s presence. These atomic-scale interactions at solid–liquid interfaces control the behavior of fuel cells and batteries used to generate clean power, as well as the effectiveness of systems used to produce clean water and many biological activities.
In our work we show that misleading information is provided if the atomic behavior is studied in vacuum instead of using our liquid cells. Professor Roman Gorbachev of the NGI developed the stacking of 2D materials for electronics; thus, his team has developed a “double graphene liquid cell” using the same methods.
The scientists were able to comprehend how the liquid affected atomic behavior by studying the movements of the atoms in the videos and comparing their findings to theoretical explanations offered by Cambridge University colleagues. It was discovered that the liquid both accelerated the atoms’ mobility and altered their preferred resting places in relation to the underlying solid.
