Non-contact atomic force microscopy (nc-AFM), also known as dynamic force microscopy (DFM), is a mode of atomic force microscopy, which itself is a type of scanning probe microscopy. In nc-AFM a sharp probe is moved close (order of Angstroms ) to the surface under study, the probe is then raster scanned across the surface, the image is then ...
An AFM generates images by scanning a small cantilever over the surface of a sample. The sharp tip on the end of the cantilever contacts the surface, bending the cantilever and changing the amount of laser light reflected into the photodiode.
Active Fuel Management (formerly known as displacement on demand (DoD)) is a trademarked name for the automobile variable displacement technology from General Motors.It allows a V6 or V8 engine to "turn off" half of the cylinders under light-load conditions to improve fuel economy.
The availability of either AFM or DFM is dependent on trim level, with WT and Custom trucks available with AFM, and LT and above trucks standard with DFM. Optional on upper-level trims is a 420-horsepower (313 kW; 426 PS), 6.2-liter EcoTec3 V8 gasoline engine with Dynamic Fuel Management (DFM).

Kelvin probe force microscopy (KPFM), also known as surface potential microscopy, is a noncontact variant of atomic force microscopy (AFM). [ 1 ] [ 2 ] [ 3 ] By raster scanning in the x,y plane the work function of the sample can be locally mapped for correlation with sample features.
