Non-sequential designation (parentheses) No plain designation exists, only designations with mission modifiers and/or status prefixes (most common designation shown) – Designation not assigned A: 1962 redesignations from the 1956 Army system: AF: 1962 redesignations from the 1924 Air Force system: N: 1962 redesignations from the 1922 Navy ...
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.
The Army Nomenclature System is designed to help accurately reference specific items which may have similar names to other items of their category.
The MOS system now had five digits, with a period after the third digit. The first four-digit code number indicated the soldier's job; the first two digits were the field code, the third digit was the sub-specialty and the fourth code number (separated by a period) was the job title.

After the Air Force separated from the Army in 1947, it retained the Army's system of MOS occupation codes, modifying them in 1954. These were 5-digit codes; for example a maintenance data systems specialist was 39150 and a weather technician was 25170.
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 ...
Non-contact mode AFM does not suffer from tip or sample degradation effects that are sometimes observed after taking numerous scans with contact AFM. This makes non-contact AFM preferable to contact AFM for measuring soft samples, e.g. biological samples and organic thin film. In the case of rigid samples, contact and non-contact images may ...
