The Electrical Resistance of AgTS-S(CH2)n-1CH3//Ga2O3/EGaIn Tunneling Junctions
(American Chemical Society (ACS), 2012)Tunneling junctions having the structure AgTS–S(CH2)n−1CH3//Ga2O3/EGaIn allow physical–organic studies of charge transport across self-assembled monolayers (SAMs). In ambient conditions, the surface of the liquid metal ... -
Electrical Textile Valves for Paper Microfluidics
(Wiley-Blackwell, 2017)This paper describes electrically-activated fluidic valves that operate based on electrowetting through textiles. The valves are fabricated from electrically conductive, insulated, hydrophobic textiles, but the concept can ... -
Electrically Activated Paper Actuators
(Wiley-Blackwell, 2016)This paper describes the design and fabrication of electrically controlled paper actuators that operate based on the dimensional changes that occur in paper when the moisture absorbed on the surface of the cellulose fibers ... -
Electrically pumped semiconductor laser with monolithic control of circular polarization
(National Academy of Sciences, 2014)We demonstrate surface emission of terahertz (THz) frequency radiation from a monolithic quantum cascade laser with built-in control over the degree of circular polarization by " fishbone" gratings composed of orthogonally ... -
Electrically switchable anisotropic polariton propagation in a ferroelectric van der Waals semiconductor
(Springer Science and Business Media LLC, 2023-01-23)Tailoring of the propagation dynamics of exciton-polaritons in two-dimensional quantum materials has shown extraordinary promise to enable nanoscale control of electromagnetic fields. Varying permittivities along crystal ... -

Electrically tunable window device
(The Optical Society, 2016)A device for controlling the transmittance of light over large areas, such as windows, is described. It is based on electrostatically induced surface deformation of soft dielectric elastomer sheets produced when a voltage ... -
Electrically-latched compliant jumping mechanism based on a dielectric elastomer actuator
(IOP Publishing, 2019-08-12)Jumping mechanisms are useful in robotics for locomotion in unstructured environments, or for self-righting abilities. However, most rigid robots rely on impact with the ground to jump, thereby requiring a relatively rigid, ... -
Electrically-tunable surface deformation of a soft elastomer
(Royal Society of Chemistry (RSC), 2016)The flat surface of a thin elastomer on a conducting substrate can be deformed by applying an electric field to a percolating network of metallic nanowires randomly dispersed over the surface. The magnitude of the field-induced ... -
Electricity Storage for Intermittent Renewable Sources
(Royal Society of Chemistry, 2012)With sufficient electricity storage capacity, any power production profile may be mapped onto any desired supply profile. We present a framework to determine the required storage power as a function of time for any power ... -
Electro-Acoustic Modulation of Surface Acoustic Waves on Thin-Film Lithium Niobate Substrate
(2020-03)Surface Acoustic Waves (SAWs) are an important physical phenomenon that could allow for universal coupling between solid state systems such as two-level quantum systems, and for applications in modern high-data rate signal ... -
Electro-optical testing of fully depleted CCD image sensors for the Large Synoptic Survey Telescope camera
(Society of Photo-optical Instrumentation Engineers, 2014)The LSST Camera science sensor array will incorporate 189 large format Charge Coupled Device (CCD) image sensors. Each CCD will include over 16 million pixels and will be divided into 16 equally sized segments and each ... -
Electroanalytical devices with pins and thread
(Royal Society of Chemistry (RSC), 2016)This work describes the adaptive use of conventional stainless steel pins—used in unmodified form or coated with carbon paste—as working, counter, and quasi-reference electrodes in electrochemical devices fabricated using ... -
The Electrocatalytic Evolution of Oxygen and Hydrogen by Cobalt and Nickel Compounds
(2015-05-21)In order to meet the ever-increasing demand for energy, a worldwide transition away from fossil fuels to renewable solar–fuels is required. However, the intermittency of local insolation mandates a cost-effective and ... -
