Eco-friendly highly efficient BN/rGO/TiO2 nanocomposite visible-light photocatalyst for phenol mineralization
(
Springer
, 2021 , Article)
Boron nitride (BN) and reduced graphene oxide (rGO) of different loadings were composited with commercial P25 TiO2 (Ti) through the hydrothermal method. The as-prepared nanocomposites were characterized using various ...
Synthesis and Optimization of a Highly Stable and Efficient BN/TiO2 Nanocomposite for Phenol Degradation: A Photocatalytic, Mechanistic and Environmental Impact Study
(
Wiley
, 2021 , Article)
Different BN/TiO2 nanocomposites were prepared hydrothermally, and their ratio was optimized to get the best photocatalytic performance towards phenol degradation. They were characterized by x-ray photoelectron spectroscopy, ...
Estimating Seroprevalence of Herpes Simplex Virus Type 1 among Different Middle East and North African Male Populations Residing in Qatar
(
Wiley
, 2017 , Article)
HSV-1 epidemiology in the Middle East and North Africa (MENA) remains poorly understood. Our study aimed to measure HSV-1 antibody prevalence (seroprevalence) and its age-distribution among select MENA populations residing ...
First study in Qatar to reveal high Legionella counts in cooling towers.
(
World Health Organization (WHO)
, 2017 , Other)
Legionella spp. is transmitted from water to humans by aerosol-generating devices, including cooling
towers (CTs). There have not been published reports about Legionella in these systems in Qatar. Ten CTs in Qatar
University ...
Herpes Simplex Virus Type 2 Seroprevalence Among Different National Populations of Middle East and North African Men
(
Lippincott, Williams & Wilkins
, 2018 , Article)
BACKGROUND:
There are limited data on herpes simplex virus type 2 (HSV-2) seroprevalence in the Middle East and North Africa (MENA). We examined country- and age-specific HSV-2 seroprevalence among select MENA populations ...
Demographic and Clinical Characteristics of Early Travel-Associated COVID-19 Cases

Frontiers Media
, 2020 , Article)
© Copyright © 2020 Marei, Emara, Elsaied, Nasrallah, Chivese, Al-Romaihi, Althani, Al Thani, Farag and Yassine. Background: SARS-CoV-2 continues to claim hundreds of thousands of people's lives. It mostly affects the elderly ...
Performance evaluation of five commercial assays in assessing seroprevalence of HEV antibodies among blood donors
(
Microbiology Society
, 2018 , Article)
Although hepatitis E virus (HEV) is mainly transmitted via the faecal-oral route, the rate of HEV transmission via blood donation is on the rise. However, the seroprevalence of HEV among blood donors is not well established ...
Effects of SARS-CoV-2 Alpha, Beta, and Delta variants, age, vaccination, and prior infection on infectiousness of SARS-CoV-2 infections
(
Frontiers Media
, 2022 , Article)
In 2021, Qatar experienced considerable incidence of SARS-CoV-2 infection that was dominated sequentially by the Alpha, Beta, and Delta variants. Using the cycle threshold (Ct) value of an RT-qPCR-positive test to proxy ...
Covid-19 Vaccine Protection among Children and Adolescents in Qatar.
(
Massachusetts Medical Society
, 2022 , Article)
The BNT162b2 vaccine against coronavirus disease 2019 (Covid-19) has been authorized for use in children 5 to 11 years of age and adolescents 12 to 17 years of age but in different antigen doses. We assessed the real-world ...
Duration of immune protection of SARS-CoV-2 natural infection against reinfection.
(
Oxford University Press
, 2022 , Article)
The future of the SARS-CoV-2 pandemic hinges on virus evolution and duration of immune protection of natural infection against reinfection. We investigated duration of protection afforded by natural infection, the effect ...
