In this study, the vibration behavior of functional graded (FG) circular and annular nanoplate embedded in Visco-Pasternak foundation and coupled with temperature change is studied. It is assumed that a uniform radial magnetic field acts on the top surface of the plate and the magnetic permeability coefficient of the plate along its thickness are assumed to vary according to the volume distribu...

Highly surface-roughened Ag nanoplate arrays are fabricated using a simple electrodeposition and in situ electrocorrosion method with inorganic borate ions as capping agent. The electrocorrosion process is induced by a change in the local pH value during the electrochemical growth, which is used to intentionally carve the electrodeposited structures. The three dimensionally arranged Ag nanoplat...

Abstract Converting mechanical energy from either the ambient environment or human body motions to useful electrical will revolutionize power solutions for flexible electronics. Here, a hybrid harvesting strategy is reported, which combines porous polymeric piezoelectric film with an electrostatic layer as integration converting into energy. The materials through engineered microstructures are ...

Nanopillar films of Al-Nb alloys have been fabricated on substrates with a regular concave cell structure by oblique angle physical vapor deposition. The concave cell structure of substrate increases the shadow region for the flux of depositing atoms, assisting the formation of an isolated nanopillar on each cell. Depending upon the alloy composition and deposition angle, the pillar shape chang...

The multi-functional nanomaterial constructed with more than one type of materials has gained a great attention due to its promising application. Here, a high white light photodetector prototype established with two-dimensional material (2D) and 2D nanocomposites has been fabricated. The 2D-2D nanocomposites were synthesized with SnSe nanoplate and graphene. The device shows a linear I-V charac...

There is evidence to support the claim that speedbreakers can cause accidents and injury. When a vehicle approaches a speed-breaker at a speed greater than some threshold velocity, the risk of accident or injury is substantial. Speed-breakers are inconspicuous in low visibility conditions, like at night, or when there is fog, rain or snow. This problem is particularly acute in developing countr...

Multi-stimuli-responsive/-functional polymeric materials can respond to numerous stimuli and execute multiple tasks, overcoming barriers faced by single-stimuli materials. Herein, the development of hybrid piezoelectric–magnetic self-sensing actuator (HPMSA) that both sense actuate is proposed. This iron oxide/functionalized carbon nanotube/polyvinylidene fluoride film optimizes piezoelectric m...

This paper describes an investigation into mechanical cross talk within 1-3 and 2-2 connectivity piezoelectric composite array configurations, comprising a matrix of active piezoelectric elements embedded within a passive, polymeric, material. One way to take full advantage of the reported sensitivity and bandwidth improvements from single crystal materials is to configure them as a piezoelectr...
