Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... En savoir plus
Approximately 450,000 people worldwide suffering from hearing problems use cochlear implants (http://www.cochlear.com/au/home/connect/cochlear-hearing-ambassador, June 12, 2018). Manual insertion of the cochlear implant during surgery can potentially damage the delicate tissues within ... En savoir plus
We report the reversible thermoelectric switching [1, 2, 3] induced by a time dependent and frequency domain electric field (or AC voltage) in a microscopic single contact nano-device based on Gold and Vanadium Oxide, which promises potential applications for future information storage ...

Recent developments (1) in thermal metamaterials that enhance the response of thermoelectric generators (TEG) have revived the interest in TEG research. The COMSOL Multiphysics® software offers the unique opportunity to model TEGs with various cooling systems (air, water, etc) and ... En savoir plus
Arc plasma can heat and melt the metal material and flows of molten metal can be affected by several forces such as Lorentz force which is ruled by current, Marangoni force controlled by surface tension, buoyancy force, and arc drag force. Usually, surface tension variation is determined ... En savoir plus
Microheaters used for gas sensing applications have been studied analytically and experimentally. Previously reported microheaters at COMSOL® conferences have shed light on microheaters’ thermal properties, optimized geometries and power consumption—all based on steady-state analysis. In ...

There is great interest in developing all-solid-state lithium-ion batteries. They are ideal micro-power sources for many applications in portable electronic devices, electric vehicles and biomedical engineering. The batteries are possessed of high energy and power densities, good ... En savoir plus
The COMSOL Multiphysics® software has proved itself an invaluable tool for teaching "Transport Phenomena" to graduate and undergraduate engineers. In particular, the software allows us to visualize and explore solutions well beyond what students could do with pencil and paper. For ... En savoir plus
Concerning the reduction of fossil-energy use from industrial processes, power generation and transportation, concentrated solar power from dish reflectors is well suited for driving highly endothermic reactions that valorize CO2 and/or light hydrocarbons. In this study, a directly ... En savoir plus
Hydrogen has great potential to be the fuel of the future through utilization in fuel cells, but it is rarely found naturally and must be produced in energy-intensive processes. Steam reforming, the process of heating natural gas and steam in the presence of a catalyst to drive a ... En savoir plus
