Electrified CO2 valorization driven by direct Joule heating of catalytic cellular substrates

Remote Joule heating by a carbon nanotube.

Minimizing Joule heating remains an important goal in the design of electronic devices. The prevailing model of Joule heating relies on a simple semiclassical picture in which electrons collide with the atoms of a conductor, generating heat locally and only in regions of non-zero current density, and this model has been supported by most experiments. Recently, however, it has been predicted tha...

Jupiter Thermospheric General Circulation Model (JTGCM): Global structure and dynamics driven by auroral and Joule heating

[1] A growing multispectral database plus recent Galileo descent measurements are being used to construct a self-consistent picture of the Jupiter thermosphere/ionosphere system. The proper characterization of Jupiter’s upper atmosphere, embedded ionosphere, and auroral features requires the examination of underlying processes, including the feedbacks of energetics, neutral-ion dynamics, compos...

Polycrystalline Silicon Produced by Joule-Heating Induced Crystallization

An electric field was applied to a conductive layer to induce Joule heating in order to generate the intense heat needed to carry out the crystallization of amorphous silicon. Complete crystallization was observed via Joule heating under typical processing conditions. Crystallization was accomplished throughout the sample within the range of microseconds of the heating, thus demonstrating the p...

Nanomechanical Optical Fiber with Embedded Electrodes Actuated by Joule Heating

Nanomechanical optical fibers with metal electrodes embedded in the jacket were fabricated by a multi-material co-draw technique. At the center of the fibers, two glass cores suspended by thin membranes and surrounded by air form a directional coupler that is highly temperature-dependent. We demonstrate optical switching between the two fiber cores by Joule heating of the electrodes with as lit...
