Harnessing rhizospheric core microbiomes from arid regions for enhancing date palm resilience to climate change effects
( Frontiers Media , 2024 , Article Review)Date palm cultivation has thrived in the Gulf Cooperation Council region since ancient times, where it represents a vital sector in agricultural and socio-economic development. However, climate change conditions prevailing ... -
The Effects of Salinity and Genotype on the Rhizospheric Mycobiomes in Date Palm Seedlings.
( MDPI , 2024 , Article)Salinity severely affects the health and productivity of plants, with root-associated microbes, including fungi, potentially playing a crucial role in mitigating this effect and promoting plant health. This study employed ... -
Functionalized cellulose nanocrystals extracted from date pits as agricultural waste for the efficient remediation of molybdenum from groundwater: Performance and mechanistic studies
( Elsevier , 2024 , Article)The adsorption technique has proven to be an excellent option for treating contaminated water. This work was designed to investigate the efficient remediation of molybdenum (Mo(VI)) from groundwater by using a novel adsorbent ... -
Removal of heavy metals from wastewater by aerogel derived from date palm waste
( Elsevier , 2024 , Article)Cellulose that has been sourced from date palm leaves as a primary component was utilised. This cellulose served as the foundational material for the development of an aerogel composite. During this process, MXene (Ti3C2Tx) ... -
Human health risk assessment associated with the reuse of treated wastewater in arid areas
( Elsevier , 2024 , Article)Qatar produces more than 850,000 m3/day of highly treated wastewater. The present study aims at characterizing the effluents coming out of three central wastewater treatment plants (WWTPs) of chemical pollutants including ... -
Groundwater Contamination in Arid Coastal Areas: Qatar as a Case Study.
( Wiley , 2024 , Article)The Arab region is located in an arid environment and suffers from water scarcity and poor water quality which are expected to become more severe in coming years due to global warming. In this study, the groundwater quality ... -
