Dynamics of photothermally driven VO2-coated microcantilevers
The dynamic response of VO2-coated silicon microcantilevers thermally driven over the film’s insulator-to-metal transition was studied using laser light pulses directly incident on the cantilevers. The measured photothermal response revealed very high curvature changes of approximately 2500 m 1 up to pulse frequencies greater than 100 Hz and readily observable vibrations up to frequencies of a ...
متن کاملNQR Characteristics of an RDX Plastic Explosives Simulant
For reliable detection of explosives, a combination of methods integrated within a single measurement platform may increase detection performance. However, the efficient field testing of such measurement platforms requires the use of inexplosive simulants that are detectable by a wide range of methods. Physical parameters such as simulant density, elemental composition and crystalline structure...
متن کاملGeneralized model of resonant polymer-coated microcantilevers in viscous liquid media.
Expressions describing the resonant frequency and quality factor of a dynamically driven, polymer-coated microcantilever in a viscous liquid medium have been obtained. These generalized formulas are used to describe the effects the operational medium and the viscoelastic coating have on the device sensitivity when used in liquid-phase chemical sensing applications. Shifts in the resonant freque...
متن کاملPlastic yield inception of an indented coated flat and comparison with a flattened coated sphere
The yield inception of a deformable hard coated half space indented by a rigid sphere is studied. The effect of coating thickness, sphere radius and material properties of both the coating and substrate on the critical contact parameters at yield inception is investigated. Dimensionless empirical expressions for the critical load, critical contact area and critical interference are derived as f...
متن کاملThin-Film Coated Plastic Wrap for Food Packaging
In this study, the antimicrobial property and food package capability of polymethylpentene (PMP) substrate with silicon oxdie (SiOx) and organic silicon (SiCxHy) stacked layers deposited by an inductively coupled plasma chemical vapor deposition system were investigated. The experimental results show that the stacked pair number of SiOx/SiCxHy on PMP is limited to three pairs, beyond which the ...
