Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at ...

Plasmonic nanogap confinement extends sum frequency vibrational spectroscopy to the nanoscale, enabling direct imaging of ...

In some materials, spins form complex magnetic structures within the nanometer and micrometer scale in which the magnetization direction twists and curls along specific directions. Examples of such ...

Cilia are micrometer-sized biological structures that occur frequently in nature. Their characteristic high-frequency, ...
