Quantitative Nanomechanical Property Mapping and in situ SPM Imaging of Polyetherimide Nanocomposites

High Speed SPM for Novel Property Mapping of Functional Ceramics

Functional ceramics are crucial to a wide range of advanced technologies, including sensors and actuators, power generation and storage, computing and data storage, etc. The incessant demand for enhanced performance in smaller and lower-power packages necessitates a thorough understanding of these systems, typically at the microto nano-scale. In ceramics, this is often especially true at interf...

In-situ Quantitative Integrated Tribo-SPM Nano-Micro-Metrology

A novel quantitative nano+micro-tribometer with integrated SPM and optical microscope imaging has been developed to characterize numerous physical and mechanical properties of liquid and solid thin films and coatings, with in-situ monitoring their changes during micro and nano indentation, scratching, reciprocating, rotating and other tribology tests. Both the materials properties and surface t...

Atomic force microscopy of red-light photoreceptors using peakforce quantitative nanomechanical property mapping.

Atomic force microscopy (AFM) uses a pyramidal tip attached to a cantilever to probe the force response of a surface. The deflections of the tip can be measured to ~10 pN by a laser and sectored detector, which can be converted to image topography. Amplitude modulation or "tapping mode" AFM involves the probe making intermittent contact with the surface while oscillating at its resonant frequen...

In-situ synthesis and characterization of conducting metal — polyaniline nanocomposites

Metal—Polyaniline nanocomposites such as Platinum-Polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of Pt+4 ions into Pt nanoparticles. Thepolymerization of aniline was carried out in the presence of 1(2PtCN6 [Potassium Hexa CyanoPlatinate (IV)] as oxidizing agent. During the reaction aniline monomers undergo oxidation andform polyaniline (PANT) w...
