scanning impedance microscopy (sim) is one of the novel scanning probe microscopy (spm) techniques, which has been developed to taking image from sample surface, providing quantitative information with high lateral resolution on the interface capacitance, and investigating the local capacitance–voltage (c–v) behavior of the interface and ac transport properties. the sim is an ordinary afm equip...
چکیده ندارد.
Atomic force microscope (AFM) has been developed at first for topography imaging; in addition, it is used for characterization of mechanical properties. Most researches have been primarily focused on rectangular single-beam probes to make vibration models simple. Recently, the U-shaped AFM probe is employed to determine sample elastic properties and has been developed to heat samples locally. I...
Background and Aims: Electric pulp testing is used for diagnosis of the pulp status. This test is technique sensitive and hence may elicit positive or negative false response in case of inaccurate use. The optimal site for placement of the probe tip has not been determined. The aim of this study was to evaluate the effect of pulp tester probe placement site on the response of maxillary teeth.Ma...
background: this study was planned to examine the effects of whole-body exposure to gsm-950 mhz electromagnetic fields (emfs) on acquisition and consolidation of spatial memory in rats using a water maze task. materials and methods: in experiment 1, the animals were given two blocks of five trials per day for three consecutive days in a water maze task. the interval between blocks was 4h. befor...
