(
Springer Verlag
, 2017 , Article)
Blend membranes of sulfonated poly(ether ether ketone) (SPEEK) and sulfonated polyetherimide (SPEI) have been prepared and investigated as a potential polymer electrolyte membrane (PEM) for direct methanol fuel cell (DMFC). ...
3D Beamforming with Massive Cylindrical Arrays for Physical Layer Secure Data Transmission
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this letter, a novel approach for physical layer security is implemented using massive cylindrical antenna arrays. A part of the arrays is used for transmitting a signal reliably from source to destination using highly ...
Potential of mercury-tolerant bacteria for bio-uptake of mercury leached from discarded fluorescent lamps
(
Academic Press
, 2019 , Article)
In this study, ten bacterial strains were found to be mercury resistant after their isolation from Qatari coastal sediments. Tolerance was found to be up to 100–150 ppm for five strains. Those strains had optimum growth ...
