Immobilization of heavy metals by microbially induced carbonate precipitation using hydrocarbon-degrading ureolytic bacteria
(
Elsevier
, 2022 , Article)
Crude oil contamination introduces multiple threats to human health and the environment, most of which are from toxic heavy metals. Heavy metals cause significant threats because of their persistence, toxicity, and ...
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 ...
Bio self-healing concrete using MICP by an indigenous Bacillus cereus strain isolated from Qatari soil
(
Elsevier
, 2022 , Article)
In this study, the self-healing process in concrete through microbial-induced calcium carbonate precipitation (MICP) performed by an adapted indigenous strain of Bacillus cereus isolated from soils in Qatar was investigated. ...
Mapping of aeolian deposits of an industrial site in the arid region using the TIR bands of ASTER and study of physicochemical characters and stabilization of sand erosion
(
Taylor and Francis Group
, 2022 , Article)
This study describes the spectral emissive character of silicate and carbonate minerals of aeolian deposits and maps the deposits and sand encroachments that occurred in and around the site 5/6 of Qatar Fertilizer Company ...
Systematic laboratory approach to produce Mg-rich carbonates at low temperature
(
Royal Society of Chemistry
, 2021 , Article)
Dolomite is a common Mg-rich carbonate in the geological record, but the mechanism of its formation remains unclear. At low temperature, the incorporation of magnesium ions into the carbonate minerals necessary to form ...
Insights into the interaction between mineral formation and heavy metals immobilization, mediated by Virgibacillus exopolymeric substances
(
Elsevier
, 2024 , Article)
Heavy metal pollution poses significant risks to both the environment and human health due to their toxicity, long residence times, and their ability to bioaccumulate and bio magnify across the food chain. To address this ...
