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-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 ... -
Electrochemical Acceleration of Chemical Weathering as an Energetically Feasible Approach to Mitigating Anthropogenic Climate Change
(American Chemical Society, 2007)We describe an approach to CO<sub>2</sub> capture and storage from the atmosphere that involves enhancing the solubility of CO<sub>2</sub> in the ocean by a process equivalent to the natural silicate weathering reaction. ... -
