Description
The
liquid-solid interface plays an essential role in many phenomena encountered in
biological, chemical, and physical processes relevant to both fundamental and
applied science. However, study of the hydrated materials such corroded
interfaces or hydrated proteins is challenging as liquid water is generally
incompatible with many analytical imaging techniques that require high to
ultrahigh vacuum conditions. One strategy to probe hydrated materials is to
cryogenically freeze the liquid into solid form to preserve local ionic
chemistry gradients and surface composition within a solid structure, making it
more amendable to vacuum-based analyses such as Atom Probe Tomography (APT).
