Poly(glutamic acid) nanofibre modified glassy carbon electrode: Characterization by atomic force microscopy, voltammetry and electrochemical impedance
(Pergamon-Elsevier B.V. Ltd, 2008-04-20)
Glassy carbon electrodes (GCE) were modified with poly(glutamic acid) acid films prepared using three different procedures: glutamic acid monomer electropolymerization (MONO), evaporation of poly(glutamic acid) (PAG) and ...

Forced oscillations with continuum models of atomic force microscopy
(2012-12-01)
The dynamics of the AFM-atomic force microscope follows a model based in a Timoshenko cantilever beam with a tip attached at the free end and acting with the surface of a sample. General boundary conditions arise when the ...
Phase-Locked loops lock-in range in Frequency Modulated-Atomic Force Microscope nonlinear control system
(Elsevier B.V., 2012-07-01)
Since the mid 1980s the Atomic Force Microscope is one the most powerful tools to perform surface investigation, and since 1995 Non-Contact AFM achieved true atomic resolution. The Frequency-Modulated Atomic Force Microscope ...

Mapping of adhesion forces on soil minerals in air and water by atomic force spectroscopy (AFS)
(Vsp Bv, 2003-01-01)
The adhesion force between an atomic force microscope (AFM) tip and sample surfaces, mica and quartz substrates, was measured in air and water. The force curves show that the adhesion has a strong dependence on both the ...
