Abstract: Unidirectional acoustic transmission is acquired in a one-dimensional graded phononic crystal. The distinct feature of the present design is that waves can propagate unidirectionally at a certain frequency from the left ...

Abstract: To make sure the safety, durability, and serviceability of structures in-service, health monitoring systems (HMS) are widely used in management of civil infrastructures in recent years. Compared with traditional force ...

Abstract: Flexible piezoelectric energy harvesters (FPEHs) have attracted tremendous attention due to their potential applications in the field of biomedicine, such as powering implantable devices. Despite observations in numerous ...

Abstract: Singlewalled carbon nanotubes (SWNTs) are of significant interest in the electronic materials research community due to their excellent electrical properties and many promising applications. However, SWNTs grow as mixture ...

Abstract: An analytical model, validated by experiments and finite element simulations, is developed to study the thermal imaging of singlewalled carbon nanotube (SWNT) devices by scanning Joule expansion microscopy (SJEM). A simple ...
