Principle and applications of peak force infrared microscopy

Chemical Society Reviews, 2022
Peak force infrared (PFIR) microscopy is an atomic force microscopy-based infrared microscopy with multimodal characterization capabilities. PFIR microscopy allows ∼10 nm spatial resolution chemical imaging in both the air and liquid phases.

Dual-Color Peak Force Infrared Microscopy

Analytical Chemistry, 2021
Peak force infrared (PFIR) microscopy achieves nanoscale infrared imaging at sub-10 nm spatial resolution through photothermal mechanical detection of atomic force microscopy (AFM). However, it suffers from a major limitation that only one infrared frequency can be scanned for an AFM frame at a time.

On the Relationship Between Peak Force and Peak Force Variability in Isometric Tasks

Journal of Motor Behavior, 1985
An experiment is reported documenting the relationship between peak force and peak force variability with a fixed criterion time to peak force for an isometric task requiring activation of the elbow flexors. The results show that maximum peak force increases with increments in time to peak force and that peak force variability increases with increments
