Enhanced tensile strength, fracture toughness and piezoresistive performances of CNT based epoxy nanocomposites using toroidal stirring assisted ultra-sonication
Esmaeili, A.; Sbarufatti, C.; Youssef, K.; Jiménez-Suárez, A.; Ureña, A.; Hamouda, A. M.S.... more authors ... less authors ( Taylor & Francis , 2021 , Article)The importance of proper CNT dispersion is still the main challenge in CNTs doped epoxy nanocomposites. Therefore, this study was aimed to investigate the effect of toroidal stirring-assisted sonication on final mechanical, ... -
High strength, ductility, and electrical conductivity of in-situ consolidated nanocrystalline Cu-1%Nb
Youssef K.M.; Abaza M.A.; Scattergood R.O.; Koch C.C. ( Elsevier Ltd , 2018 , Article)Nanocrystalline metals—with grain sizes less than 100 nm— have strengths exceeding those of coarse-grained and even alloyed metals [1], [2]. A bulk nanocrystalline Cu-1%Nb alloy was synthesized by an in-situ consolidation ... -
Influence of 1%Nb Solute Addition on the Thermal Stability of In Situ Consolidated Nanocrystalline Cu
Abaza M.A.; Al-Sulaiti L.; Scattergood R.O.; Youssef K.M. ( Wiley-VCH Verlag , 2019 , Article)Nanocrystalline (nc) Cu and Cu–1% Nb bulk materials are synthesized using a combination of cryogenic and room temperature ball milling. The grain size values of these in situ consolidated Cu and Cu–1% Nb, determined using ... -
Rational synthesis of ternary PtIrNi nanocrystals with enhanced poisoning tolerance for electrochemical ethanol oxidation
Ahmad Y.H.; Mohamed A.T.; Youssef K.M.; Kundu S.; Mkhoyan K.A.; Al-Qaradawi S.Y.... more authors ... less authors ( Elsevier Inc. , 2019 , Article)The development of highly efficient and durable anode materials for ethanol electro-oxidation remains a challenge. Herein, we report the synthesis of Pt1−x−yIrxNiy nanocrystals via one-step procedure by ultrasonic-assisted ...
