Active Phase-Change Metasurfaces for Convolutional Image Processing
(E\PCOS, 23 September 2024)Non-local phase-change optical metasurfaces are designed for reconfigurable free-space edge detection/bright-field and edge-detection/blurred imaging functionality. Active reconfigurability is achieved via switching the ... -
GeSbSeTe Phase-change Material for Write-once and Rewritable Flexible Non-volatile Memories
(E\PCOS, 23 September 2024)The phase-change material Ge2Sb2Se4Te1 (GSST) is investigated for use in flexible non-volatile memory applications. Modified pore cell structures on polyimide substrates are fabricated using this material and their switching ... -
Optimising the readout process in integrated phase-change photonic memory and computing devices
(E\PCOS, 23 September 2024)In integrated phase-change photonic memory and computing devices, the basic operation involves using light guided into an integrated waveguide to switch the phase-change cell between its crystalline and amorphous states. ... -
The Resilience of Intermittent Water Supply Systems under Limited Water and Electricity Availability
(MDPI, 10 September 2024)Two main reasons for using intermittent water supply (IWS) systems are water scarcity and power outages. As a result of IWS systems, consumers have inequitable water supply and high operating costs for water utilities. ... -
Optimization of hydrogen recirculation ejector for proton-exchange membrane fuel cells (PEMFC) systems considering non-equilibrium condensation
(Elsevier, 29 October 2024)In proton exchange membrane fuel cell (PEMFC) systems, unconsumed hydrogen recirculation is enabled by utilizing an ejector, and the PEMFC system's efficiency is thereby enhanced. Apart from the structural parameters, an ...
