Enhancement of Naphthalene Biodegradation by Sulfate Application in Brackish Subsurface Systems
(
Qatar Univesrity Press
, 2020 , Conference Paper)
Anaerobic biodegradation is the most dominant mechanism in the petroleum hydrocarbon
contaminated subsurface systems. Due to depletion of terminal electron acceptors such
as sulfate, anaerobic degradation of organic ...

(
Qatar University Press
, 2023 , Conference Paper)
This paper describes the outcomes of a preliminary study focused on the evaluation of four full-scale pavement sections in which reclaimed asphalt (RAP) was used in partial substitution of virgin aggregates during the ...
Adapting Smart Street Strategy for Post-Covid Built Environment
(
Qatar University Press
, 2023 , Conference Paper)
The street networks occupy 25% of land use and are the veins of cities. By 2050, more than two-thirds of the world’s population will live in urban areas. The urban street infrastructures and systems are expected to serve ...
Synthesis of Calcium Nitrate Self-Healing Microcapsules Using Aerosol OT Hexane Solution for Cementitious Materials
(
Qatar University Press
, 2023 , Conference Paper)
Calcium nitrate synthesis of in urea-formaldehyde shell has recently been used to produce self-healing microcapsules for construction applications. The original synthesis was based on water-in-oil emulsion with sulfonic ...
