Graphene scientists from The University of Manchester have created a new ‘nano-petri dish’ using a two-dimensional (2D) material to create a new method of observing how atoms move in a liquid. Published in the journal Nature, a team led by researchers based at the National Graphene Institute (NGI) used stacks of 2D materials such as graphene to trap liquids to better understand how the presence of liquids changes the behavior of solids. The team was able to capture images of a single atom ‘swimming’ in a liquid for the first time. These findings could have far-reaching implications for the future development of green technologies such as hydrogen production. When a solid surface comes into contact with a liquid, the two substances change their configuration in response to the proximity of the other. Such atomic-scale interactions at the solid-liquid interface regulate the behavior of batteries and fuel cells for clean electricity generation, as well as determine the efficiency of cle

Single molecule images obtained by high resolution atomic force microscopy. The selective and reversible structure of the molecule in the middle can be converted to the structure on the right or on the left, with a voltage pulse applied from the tip of the scanning probe microscope. Credit: Leo Gross/IBM A team of researchers from IBM Research Europe, the Universidade de Santiago de Compostela and the University of Regensburg have changed the bonds between atoms in a molecule for the first time. In their paper published in the journal Science , the group explained their method and its possible uses. Igor Alabugin and Chaowei Hu, have published Perspectives in the same issue of the journal outlining the work carried out by the team. Current methods for making complex molecules or molecular devices, as Alagugin and Chaowei note, are generally quite challenging—they liken it to throwing a box of Legos in the washing machine hoping for some usefu

The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of atomic clocks and quantum sensors, which are atomic systems whose fluctuations can indicate the presence of dark matter, passing gravitational waves, or even phenomena. unexpected new. The main obstacle on the road to better quantum measurements is noise from the classical world, which can easily overwhelm the subtle vibrations of atoms, making any changes to those vibrations extremely difficult to detect. Now, MIT physicists have shown that they can significantly amplify quantum changes in atomic vibrations, by placing particles through two key processes: quantum entanglement and time reversal. Before you start shopping for DeLoreans, no, they haven’t figured out how to turn back time itself. Instead, physicists have manipulated quantum entangled atoms in such a way that the particles beha
