Electrically-triggered micro-explosion in a graphene/SiO2/Si structure

Hybrid metamaterials for electrically triggered multifunctional control

Despite the exotic material properties that have been demonstrated to date, practical examples of versatile metamaterials remain exceedingly rare. The concept of metadevices has been proposed in the context of hybrid metamaterial composites: systems in which active materials are introduced to advance tunability, switchability and nonlinearity. In contrast to the successful hybridizations seen a...

Velocity and Density Field Measurements of a Micro- Explosion

This paper describes the implementation of Background oriented Schlieren (BOS) technique to capture the density field of a blast wave generated through a micro-explosion. The three dimensional density field was reconstructed using the filtered back projection technique. This was carried out at several instants of time in order to capture the evolution of the density field. The reconstructed den...

Mass transfer and flow in electrically charged micro- and nanochannels.

In this work, the fluid flow and mass transfer due to the presence of an electric field in a rectangular channel is examined. We consider a mixture of water or another neutral solvent and a salt compound, such as sodium chloride, for which the ionic species are entirely dissociated. Results are produced for the case in which the channel height is much greater than the electric double layer (EDL...

Sulfur Trioxide Micro-Thermal Explosion for Rice Straw Pretreatment

Electrically Triggered Release of a Small Molecule Drug from a Polyelectrolyte Multilayer Coating.

Electrically triggered drug delivery represents an attractive option for actively and remotely controlling the release of a therapeutic from an implantable device (e.g., a "pharmacy-on-a-chip"). Here we report the fabrication of nanoscale thin films that can release precise quantities of a small molecule drug in response to application of a small, anodic electric potential of at least +0.5 V ve...
