AFM atomic force microscope Articles

Automating the task of nanomanipulation is extremely important since it is tedious for humans. This paper proposes an atomic force microscope (AFM) based force controller to push nano particles on the substrates. A block phase correlation-based algorithm is embedded into the controller for the compensation of the thermal drift which is considered as the main external uncertainty during ...

This paper presents the application of the concept of boundary conditioning to the prediction of spring constant of atomic force microscope (AFM) cantilevers after considering the inherent microfabrication limitations. The boundary support conditions of micromechanical structures such as AFM probes are non-classical in nature, and they influence the modal response and natural frequencies of the ...

In using the frequency domain as a unified platform for representing topology of the sample and capabilities of an instrument, it is shown that instrument transfer functions, when applied to scanned probe instruments such as the atomic force microscope, serve as a powerful design and analysis tool. An instrument transfer function approach is proposed to capture the characteristics of atomic force ...

The aim of this research is using different doses of UVB radiation to study the influence on the cell behaviour and elasticity of Hs68 human dermal fibroblasts. These studies include cell viability analysis, proliferation index, gene expression and Young's modulus measurement using atomic force microscope (AFM). Results have exhibited that the cell viability was 100%, 89.46%, 73.76% and 70.75% ...

The use of amphoteric chitosan/gelatin composite microspheres (CGMSs) has been studied as an adsorbent for the removal of Acid Red 337 (AR337) from wastewater. The adsorbent was characterized by using several methods such as scanning electron microscopy and atomic force microscope (AFM). The kinetic study was performed based on pseudo-first-order, pseudo-second-order, and intraparticle ...

The sulphate-reducing bacteria strain H1 with the function for Hydrolysed Polyacrylamide (HPAM) degradation was isolated from a curing pot in the HPAM distribution station of Daqing Oil Field using the Hungate Anaerobic Technique. The isolates were characterised morphologically, physiologically, biochemically and molecularly. The pictures of the Atomic Force Microscope (AFM) have shown that this ...

The problems of scale are well known to those living and working in "hard" water areas. Scale is the undesirable consequence of water supplies becoming super-saturated with dissolved minerals.  These problems are of greater significance if found in industrial water systems and commercial buildings. Scaling problems commonly occur, even in "soft" water areas, when a fluid stream is ...

In this study, high orientation InN films were prepared on Si (100) substrates using plasma–assist metal–organic molecular beam epitaxy (RF–MOMBE) system. These buffers include the nitrided treatment of the Si substrate, a low–temperature AlN buffer layer and oxide layer. The crystalline structure, surface morphology and optical properties of the InN films were characterised by X–ray diffraction ...
