The closed-form solution of the transient response of damped dynamic force microscopy subjected to the nonlinear interatomic force is derived. The frequency shift and the decay rate of a V-typed probe can be determined easily and precisely by the proposed method. If the taper ratio is zero, a uniform cantilever is obtained. Moreover, the transient response of a non-uniform cantilever can be det...

The bridge of Shanghai Metro Line 10 over 6 is a U-shaped concrete single-box double-cell box beam continuous bridge. A novel method applied to construct the asymmetric cantilever prefabricated and assembled due limited construction space complex environment. Four mechanical state control methods are during T-shape structure process: tensioning pre-stressed steel strand, jacking by axial force ...

Natural and artificial superhydrophobic surfaces are a rapidly growing topic in both academia industry due to their unique properties applications. Numerous techniques have been developed characterize the wetting of such surfaces, as optical contact angle goniometer, force-based methods, microscopic for visualizing interface. However, method that combines nN resolution force measurement with di...

Cantilevers fabricated by means of micromachining techniques are usually used for atomic force microscopy. In this paper, the spring constant of an atomic force microscope (AFM) cantilever is determined by using a large-scale cantilever. Since the spring constant of the large-scale cantilever is calibrated accurately, the spring constant of the AFM cantilever is determined precisely by measurin...

The single-walled carbon-nanotube ~SWNT! was grown directly onto the top of the conventional Si atomic force microscopy ~AFM! cantilever. This SWNT AFM cantilever was introduced into the AFM nano-oxidation process, which oxidized the titanium ~Ti! metal film on the atomically flat a-Al2O3 substrate and formed the ultranarrow oxidized titanium (TiOx) line of 5 nm width. This TiOx line was used a...

The fabrication and characterisation of a double-arm cantilever-type metallic DC-contact MEMS actuator with low pull-down voltage are reported. Bi-layer TiW cantilevers with an internal stress gradient were fabricated using a microwave-compatible fabrication process. Owing to its small size, cantilever length (L 1⁄4 5–50 mm) and width (W 1⁄4 2–40 mm), i.e. 10–100 times smaller in lateral dimens...

The phase angle of the cantilever oscillation in tapping mode scanning force microscopy can be related to the energy dissipated per oscillation period through an analytical model that assumes a sinusoidal movement of the cantilever @J.
