Ultrasonic force microscopy on poly(vinyl alcohol)/SrTiO(3) nano-perovskites hybrid films.

Atomic Force Microscopy (AFM) and Ultrasonic Force Microscopy (UFM) have been applied to the characterization of composite samples formed by SrTiO3 (STO) nanoparticles (NPs) and polyvinyl alcohol (PVA). The morphological features of the STO NPs were much better resolved using UFM than contact-mode AFM topography. For high STO concentrations the individual STO NPs formed nanoclusters, which gath...

Atomic Force Microscopy at Ultrasonic Frequencies

Atomic Force Microscopy (AFM) is a near-field technique to generate high-resolution images of surfaces. A micro-fabricated elastic beam with an integrated sharp sensor tip at its end is scanned over the sample surface. With various dynamic modes, leading to Force Modulation Microscopy [1], Ultrasonic Force Microscopy [2], Atomic Force Acoustic Microscopy (AFAM) [3–5], Microdeformation Microscop...

Effective Parameters in Contact Mechanic for Micro/nano Particle Manipulation Based on Atomic Force Microscopy

The effect of geometry and material of the Micro/Nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. Hertz contact model simulation for EpH biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. Then, to val...

Surface Evaluation of Resin Zein Films Containing Sugar Plasticizers by Permeability and Atomic Force Microscopy Analysis

     Zein is one of the best biopolymer for edible film making and sugars are natural plasticizers for biopolymers. In this research, sugars (fructose, galactose and glucose) at three levels (0.5, 0.7, 1 g/g of zein) were used as plasticizers for zein protein films and their water vapor permeability (WVP), oxygen permeability (OP) and atomic force microscopy (AFM) topography were studied. The p...

Conductive Scanning Force Microscopy on Linear-chain Organic Films

The electrical properties of self-assembled monolayers (SAMs) of organic molecules on metal surfaces have gained particular interest due to their potential applications in nanometer-scaled electronics systems [1]. Understanding the transport mechanism through these thin molecular films as well as the dependence of the conductivity on the molecular length and structure, the applied load and the ...
