Published: May 23, 2024

Abstract Membrane distillation (MD) is a versatile low-temperature separation process used for desalinating saline solutions with high salt rejection rates. Its current drawbacks include low flux and energy demand. This study presents localized electrically induced heating using ceramic-coated metallic spacers to improve MD performance. We coated Ni-Cr MgO via electrolytic deposition calcination, optimizing crack-free protective surface. Smaller wire diameter exhibited superior heating. When periodic of 0.2 A cm −2 was applied, permeate increased by 15% although consumption only 4%. Continuous supply high-grade electrical added no further performance improvement as compared application. Our work highlights spacer-based approach Joule in systems without compromising membrane structure, while exploring coating protect conductive schemes controlled

Energy Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 17, 2025

A thermal‐energy‐storage (TES) system is investigated in this work. The charging process uses hot air passed through a fixed bed, transferring thermal energy to solid particles, while discharging occurs with cold flowing the opposite direction. novel automated dynamic simulation model of TES developed and validated using data from literature. This study uniquely operates heat‐transfer‐fluid (HTF) temperature up 1200 °C during charging, discharge temperatures regulated via bypass controller. Simulations explore fixed‐bed storage behaviour charging/discharging cycles, 64 parameter variations tested. In addition air, CO 2 evaluated as an HTF enhance performance due its higher density. Results show that Case C14 (using air) achieves maximum capacity 3.237 MWh utilization 55.4%. When substituted for under same parameters, increase 4.5% observed, along reduced compressor work, highlighting 's advantages improved efficiency.

Single-Step Microfluidics-Based Method for Fabrication of Nanoparticle-Coated Functional Microfibers

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: March 14, 2025

Fibers coated with nanoparticles have diverse applications as catalysts, biosensors, tissue scaffolds, and adsorbents for contaminants in water purification. However, current fabrication techniques employ multistep processes that often result uneven nanoparticle coatings, consequently leading to reduced activity. Here we present a single-step microfluidics-based approach the generation of microfibers uniformly nanoparticles. Inside microfluidic device, magnesium oxide (MgO) are deposited onto poly(vinylidene fluoride) (PVDF) polymer solution jet is solidifying into fibers through solvent evaporation. The formed display uniform coating on their surfaces, which crucial requirement all applications. Using these purification, demonstrate single adsorbent MgO can effectively remove multiple heavy metal contaminants, including As(III), As(V), Pb(II), Cd(II), both As(III) As(V) together. Remarkably, nanoparticles, when fibers, shown higher contaminant removal efficiency than used alone, arguably due greater surface area available form. developed technique could possibly be fabricate various other nanomaterial (nanorods, quantum dots, proteins) array
