Nanoscale imaging the cross section of a drop sitting on a surface

Description Nanostructured surfaces with special wetting properties can not only efficiently repel or attract liquids like water and oils but can also prevent formation of biofilms, ice, and other detrimental crystals. Such super- and ultrahydrophobic surfaces also hold the promise of significantly improving performance of condensers, which could boost the efficiency of most power plants in the world. A critical part of designing such surfaces is 'seeing' how water and other liquids interact when in contact with them. Since these surfaces are made of nanostructures, scientists need to use an electron microscope to image these interactions. In new work, researchers have developed a method for directly imaging such interfacial regions with previously unattainable nanoscale resolution.
