Alaa Mohamed,Alaa Mohamed,Samy Yousef,Mohammed Ali Abdelnaby,T. A. Osman,Bejan Hamawandi,Muhammet S. Toprak,Mamoun Muhammed,Mamoun Muhammed,Abdusalam Uheida +9 more
TL;DR: In this article, the enhanced mechanical properties of composite nanofibers and photodegradation of two organic dyes using PAN/CNTs under UV irradiation at different volume concentration were described.
Journal ArticleDOI
Multi-objective optimization of concentrated Photovoltaic-Thermoelectric hybrid system via non-dominated sorting genetic algorithm (NSGA II)
TL;DR: In this paper, the output performances of four sets of equations (models) used in the hybrid system, using the performance of recently developed nanostructured thermoelectric materials, were determined.
Journal ArticleDOI
Heat transfer study of enhanced additively manufactured minichannel heat exchangers
TL;DR: In this paper, the authors investigated the heat transfer characteristics of minichannel-based heat exchangers embedded with longitudinal vortex generators, both experimentally and numerically, and determined that the vortex generators can enhance the convective heat transfer up to three times with the designed parameter.
Journal ArticleDOI

TL;DR: The solution synthesis route as a scalable bottom-up synthetic method possesses significant advantages for synthesizing nanostructured bulk thermoelectric (TE) materials with improved performance as mentioned in this paper.
Journal ArticleDOI
Modeling, design, and synthesis of gram-scale monodispersed silver nanoparticles using microwave-assisted polyol process for metamaterial applications
TL;DR: In this article, high-yield monodispersed silver (Ag) nanospheres were modeled, designed, and synthesized by microwave-assisted polyol method from AgNO3, polyvinyl pyrrolidone (PVP), and ethylene glycol (EG), as precursors, at 145°C within a short reaction time of 2min.
