    • Control of Airborne Noise Generated in the Cavities of a T-Slotted Aluminum Cylindrical Column 

      Mustafa, Mohamad Y.; Yizhong, Xu; Sørensen, Bjørn Reidar; Santos, José; Al-Mahadin, Aziz (Peer reviewed; Chapter, 2018-06-11)
      This paper presents a study of airborne noise generated by a T-slotted cylindrical aluminum hollow column with six slots of the type used for the construction of communication towers. Noise is a very distracting phenomena and an environmental concern caused by various sources. Noise pollution is becoming more severe with the introduction of massive human activities and the use of heavy machineries, ...

    • Poly[2,2′-(4,4′-bipyridine)-5,5′-bibenzimidazole] functionalization of carbon black for improving the oxidation stability and oxygen reduction reaction of fuel cells 

      Berber, Mohamed R.; Mustafa, Mohamad Y. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-20)
      The rapid oxidation of carbon black (CB) is a major drawback for its use as a catalyst support in polymer electrolyte fuel cells. Here, we synthesize poly[2,20 -(4,40 -bipyridine)-5,50 -bibenzimidazole] (BiPyPBI) as a conducting polymer and use it to functionalize the surface of CB and homogenously anchor platinum metal nanoparticles (Pt-NPs) on a CB surface. The as-prepared materials were ...

    • Surface Functionalization of Carbon Nanotubes for Energy Applications 

      Berber, Mohamaed; Hafez, Inas H.; Mustafa, Mohamad Y. (Peer reviewed; Chapter, 2018-05-05)
      Carbon nanotubes (CNTs) are receiving a great deal of attention as a catalyst support for different energy applications, due to their high surface area and high conductivity. Recent literature studies have shown that the application of CNTs mainly depends on their surface functionalization process. Typically, pristine CNTs (as produced) have no functional groups, which is usually considered as an ...
