Electrohydrodynamic inkjet printing of reduced graphene oxide (RGO) is de-monstrated to form complex geometric devices with high resolution (line width ≈ 5 mm). Both planar and highly curved surfaces (radius of curvature ≈ 60 mm) can be used as substrates. Demonstrations of counterfeit coin recognition using RGO patterns and all-printed RGO transistors suggest substantial promise for applicatio...

In-Flight ElectroSpraying (IFES) is a novel approach to generate electrically charged micrometer-sized and/or nanometer-sized progeny drops in a controlled manner. This is accomplished in ight, beginning with millimeter-sized parent drops. The breakup of charged drops that is exploited in IFES also occurs (sometimes unwantedly) in conventional electrospraying, electrospinning, and electrospray ...

The current socio-economic shift towards electrification of the transport sector and development hybrid thermal-electric propulsion systems provides new opportunities for ‘clean’ aviation technologies. In this work, use electrostatic fields to control location electrically charged fuel droplets is proposed as a novel technology enhance pre-evaporation liquid sprays in confined spaces. An electr...

The problem is an eighth order eigen-value one supplied with hi...

Large chemical and biological systems such as fuel cells, ion channels, molecular motors, and viruses are of great importance to the scientific community and public health. Typically, these complex systems in conjunction with their aquatic environment pose a fabulous challenge to theoretical description, simulation, and prediction. In this work, we propose a differential geometry based multisca...
