Influence of the water layer on the shear force damping in near-field microscopy

چکیده
The influence of the water layer on the shear force damping is investigated in the case of a perfectly flat mica surface. In ambient conditions it is shown that the damping curve exhibits three particular regimes depending on the tip-sample distance. Moreover, the damping varies significantly over the first hour, pointing out the complexity of the distance control by shear force detection. © 1998 American Institute of Physics. @S0003-6951~98!03244-6#

Design Spectrum for Near Fault Ground Motions Considering Frequency-Dependence of CH/SC Material Behavior Regarding Laboratory and Field Shear Wave Velocity (Vs)
Introduction One-dimensional site response analysis is widely performed to account for local site effects during an earthquake. Most of these approaches assume that dynamic soil properties are frequency independent. Laboratory test results as well as in-situ testing show that shear modulus and damping ratio are dependent on the frequency of loading. Although the amplification factor at ground ...
متن کاملDamping Ratio in Micro-Beam Resonators Based on Magneto-Thermo-Elasticity
This paper investigates damping ratio in micro-beam resonators based on magneto-thermo-elasticity. A unique aspect of the present study is the effect of permanent magnetic field on the stiffness and thermo-elastic damping of the micro resonators. In our modeling the theory of thermo-elasticity with interacting of an externally applied permanent magnetic field is taken into account. Combined the...
متن کاملEvaluating the effects of near-field earthquakes on the behavior of moment resisting frames
Following the 1994 Northridge and 1995 Kobe earthquakes, most of modern structures damaged seriously or devastated totally despite the seismic codes of these countries that had been expected to bear advanced criteria for seismic design of structures. After extensive research, the most probable reason of those destructions was attributed to special specifications of near-field earthquakes. In th...
متن کاملInfluence of Sodium Tripolyphosphate Concentration on Characteristics and Performance of Polyamide Thin Layer Membrane in Cu (II) Removal
In this work, the effect of presence of the sodium tripolyphosphate (STPP), as an inorganic salt, on improving the performance of polyamide (PA) thin layer membranes has been studied. Characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. Different salt loadings resulted in different fluxes and Cu (II) rejections. The thin layer containing...
متن کاملPerformance of Mid-rise Buildings with Tubular Structure Under the Effect of Near Field Earthquakes
The aim objective of this study is to investigate the effects of near-field earthquakes on the response of mid-rise buildings with tubular structure. For this purpose, a 20-story building with a square plan of six by six bays, all with 6 m span, and story height of 3.70 m is considered. Axial force of columns, shear lag, and inter-story drift values are used as the main response parameters. N...
