The Association of Chartered Certified Accountants (ACCA) is the global professional accounting body offering the Chartered Certified Accountant qualification (CCA). Founded in 1904, It is now the fourth-largest professional accounting body in the world, with 252,500 members and 526,000 student members.
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit.
OpenTuition have discussion forums for all ACCA papers, OBU, CIMA, FIA, AAT and others. OpenTuition received international recognition among accountancy professionals in London, winning two prizes, the first in 2010 as the best accountancy learning site [ 6 ] and in 2011 for the best accountancy study resource.
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 ...
Topographic (left) and current (right) maps collected with CAFM on a polycrystalline HfO 2 stack. The images show very good spatial correlation. In microscopy, conductive atomic force microscopy (C-AFM) or current sensing atomic force microscopy (CS-AFM) is a mode in atomic force microscopy (AFM) that simultaneously measures the topography of a material and the electric current flow at the ...
Figure 1: Photograph of an AFM system which can be used for chemical force microscopy. In materials science, chemical force microscopy (CFM) is a variation of atomic force microscopy (AFM) which has become a versatile tool for characterization of materials surfaces.
The Lockheed Martin X-55 Advanced Composite Cargo Aircraft (ACCA) is an experimental twinjet transport aircraft. It is intended to demonstrate new air cargo -carrier capabilities using advanced composite materials .
