The dielectric studies on sol–gel routed molybdenum oxide thin film [PDF]

open access: yesJournal of Advanced Dielectrics, 2017
The influence of temperature on the dielectric properties of sol-gel routed spin-coated molybdenum trioxide (MoO3) thin film has been investigated. Prepared films were annealed at temperatures 250∘C, 350∘C and 400∘C.

Optimizing Atmospheric Ion Harvesting Electrodes with Graphene for Clean Energy Generation Based on Capacitive Properties and Energy Storage

open access: yesPhysics Communication
The atmosphere is rich in positive ions, rendering it electrically more positive than the Earth's surface. This characteristic presents the atmosphere as a potential source of renewable energy through ion harvesting.

Capacitively-Loaded Feed Line to Improve mm-Wave and Sub-6 GHz Antenna Co-Existence

open access: yesIEEE Access, 2020
The co-existence of millimeter-wave (mm-wave) and sub-6GHz antennas in a smartphone presents many performance-limiting aspects. When both antennas are attached to the metal frame, the feed lines of the mm-wave antennas might short-circuit the sub-6GHz ...

Ion-liquid based super-capacitors with inner gate diode-like separators

open access: yes, 2019
We demonstrate that the capacitance of ionic-liquid filled supercapacitors is substantially increased by placing a diode-like structure on the separator membrane. We call the structured separator: gate, and demonstrate that the order of a p-n layout with
