      Inert-gas condensation is a novel technique that can be used to produce nanoclusters for different applications. In the present work, dc sputtering combined with inert-gas condensation were used to produce copper oxide ...

    • Pt-doped armchair graphene nanoribbon as a promising gas sensor for CO and CO2: DFT study 

      Ehab, Salih; Ayesh, Ahmad I. ( Elsevier , 2021 , Article)
      In this work, four armchair graphene nanoribbon (AGNR) based sensor materials were built using Atomistic ToolKit Virtual NanoLab (ATK-VNL) and utilized to detect carbon monoxide (CO) and carbon dioxide (CO2) gases. First, ...

    • Selective H2S sensor based on CuO nanoparticles embedded in organic membranes 

      Ayesh, Ahmad I.; Abu-Hani, Ayah F. S.; Mahmoud, Saleh T.; Haik, Yousef ( Elsevier B.V. , 2016 , Article)
      We report on H2S gas sensors based on CuO nanoparticles that are embedded within polymer membranes of poly-vinyl-alcohol (PVA) and glycerol ionic liquid (IL). The nanoparticles were fabricated by the colloid microwave ...

    • Selective hydrogen gas sensor using CuFe 2 O 4 nanoparticle based thin film 

      Haija, Mohammad Abu; Ayesh, Ahmad I.; Ahmed, Sadiqa; Katsiotis, Marios S. ( Elsevier B.V. , 2016 , Article)
      Hydrogen gas sensors based on CuFe2O4 nanoparticle thin films are presented in this work. Each gas sensor was prepared by depositing CuFe2O4 thin film on a glass substrate by dc sputtering inside a high vacuum chamber. ...

    • Spinel ferrite nanoparticles for H2S gas sensor 

      Ayesh, Ahmad I.; Abu Haija, Mohammad; Shaheen, Adel; Banat, Fawzi ( Springer Verlag , 2017 , Article)
