Magnetical Response and Mechanical Properties of High Temperature Superconductors, YBaCu3O7-X Materials

“…The blind reconstruction software employed is Scanning Probe Image Processor, see Fig. 13 (Roa et al, 2011e). 3.…”

“…Indentation process: after that, an image of the sample should be taken, and several spots (at least 40 spots) should be chosen in order to perform one indentation per spot, see Fig. 14a (from Roa et al, 2011e). F is calculated as (see Fig.…”

Quantitative Normal Force Measurements by Means of Atomic Force Microscopy Towards the Accurate and Easy Spring Constant Determination

“…physics: the investigation of the physical principles of the adhesion changes due to varying the tip-sample distance changes speed [19], the measurements of the physical bond of the fullerene [20], biology: the measurements of the mechanical properties of the cells and tissue [21] or the proteins unfolding observation [22], chemistry: the investigation of polyazomethine compound provided an insight in the mechanical interaction between the scanning tip and submicron features, revealing their wear while the pressing cycles are repeated [23], the observation of the interaction between two poly(benzyl ether) dendrons in terms of observation of the rupture force, which indicated thermodynamic pulling property [24], material science: the deterioration of the material's surfaces due to the environmental conditions may be observed and quantified with much higher sensitivity than in case of traditional methods defined by standards [25], forensics: distinguishing of various types of adhesive tapes by the measurement of the adhesion force and adhesion energy [26], the determination of the blood spots age by the determination of the Young modulus [27], nanotribology: the investigation of various materials in terms of the resistance for mechanical wear [28]. Also unique applications of the AFM probes can be found.…”

Molecular Dynamics Study of the Tensile Deformation on Aluminum nanorod

“…However, the mechanisms exploration and microstructure characterization of nanomaterial is still difficult due to the complexity of equipments and the uncertainty of the samples. So, the simulation methods, especially molecular dynamics (MD) method, were often adopted as an optimum approaches in exploring mechanical property of nanomaterials [7][8][9][10][11][12][13][14]. Some of the simulations were conducted on single crystal to study the shearing deformation [7], the void effect [8], the softening behavior [9], the stretching deformation [10], and the effects of different model sizes, boundary conditions, crystal orientations and load speeds on tensile deformation [11].…”
