( Academic Press , 2023 , Article)The present study was done to investigate and compare the photocatalytic and antibacterial activity of two in situ Manganese doped ternary nanocomposites. The dual ternary hybrid systems comprised Mn-doped Ag2WO4 coupled ... -
Impact of SARS-CoV-2 on Ambient Air Quality in Northwest China (NWC)
( MDPI , 2021 , Article)SARS-CoV-2 was discovered in Wuhan (Hubei) in late 2019 and covered the globe by March 2020. To prevent the spread of the SARS-CoV-2 outbreak, China imposed a countrywide lockdown that significantly improved the air quality. ... -
In-site and ex-site date palm exposure to heavy metals involved infra-individual biomarkers upregulation
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)As a tree of considerable importance in arid regions—date palm, Phoenix dactylifera L. survival in contaminated areas of Sfax city has drawn our attention. Leaf samples of the plants grown in the study area showed high ... -
Indoor and Outdoor Air Pollution in Doha - cases of schools and residences
( Hamad bin Khalifa University Press (HBKU Press) , 2018 , Conference Paper)The World Health Organization (WHO) attributes air pollution to 1 in 8 deaths worldwide, where exposure to indoor air pollutants is a significant contributor to incidences of heart disease, respiratory problems, and cancer ... -
Inter-annual variability and distribution of aerosols during winters and aerosol optical thickness over Northeastern Pakistan
( Springer , 2020 , Article)ir pollution during winters over north-eastern (NE) Pakistan (71–74.5 E, 28–34 N) is a major challenge that affects human health, climate and daily life. In this article, distribution of aerosols and its optical properties ... -
Investigation and Application of Bacillus licheniformis Volatile Compounds for the Biological Control of Toxigenic Aspergillus and Penicillium spp
( American Chemical Society , 2019 , Article)The present study was designed to investigate the antagonistic activity of Bacillus licheniformis BL350-2 against mycotoxigenic strains of Aspergillus and Penicillium. In vitro coincubation for 5 days indicated Aspergillus ... -
Long-term assessment of onshore and offshore wind energy potentials of Qatar
