Solar Thermochemical Hydrogen Production via Terbium Oxide Based Redox Reactions
(
Hindawi Limited
, 2016 , Article)
The computational thermodynamic modeling of the terbium oxide based two-step solar thermochemical water splitting (Tb-WS) cycle is reported. The 1st step of the Tb-WS cycle involves thermal reduction of TbO2 into Tb and ...
An Experimental and Kinetic Study of the Sorption of Carbon Dioxide onto Amine-Treated Oil Fly Ash
(
Hindawi Publishing Corporation
, 2016 , Article)
A new CO2 adsorbent is produced from waste oil fly ash (OFA). Ammonium hydroxide solution is used to convert OFA to activated carbon. Then, the product is used for the adsorption of CO2 from a nitrogen/carbon dioxide ...
Ni incorporation in MgFe2O4 for improved CO splitting activity during solar fuel production
(
Springer
, 2020 , Article)
Efficacy of the sol–gel derived Ni-doped Mg-ferrites for an enhanced CO2 splitting activity is investigated. The results allied with the characterization indicate the formation of nominally phase pure Ni-doped Mg-ferrites ...
Instability in CH3NH3PbI3 perovskite solar cells due to elemental migration and chemical composition changes
(
Nature Publishing Group
, 2017 , Article)
Organic-inorganic halide perovskites have rapidly grown as favorable materials for photovoltaic applications, but accomplishing long-term stability is still a major research problem. This work demonstrates a new insight ...
Solar hydrogen production via a samarium oxide-based thermochemical water splitting cycle
(
MDPI AG
, 2016 , Article)
The computational thermodynamic analysis of a samarium oxide-based two-step solar thermochemical water splitting cycle is reported. The analysis is performed using HSC chemistry software and databases. The first (solar-based) ...
The carbon conundrum: GCC perspectives
(
Hamad bin Khalifa University Press (HBKU Press)
, 2012 , Article)
The solution to the carbon conundrum does not seem to be within reach in the short or medium term, despite significant advances and knowledge gains in demonstration scale CCS facilities. This stems from the fact that ...
Mesoporous biohybrid epichlorohydrin crosslinked chitosan/carbon clay adsorbent for effective cationic and anionic dyes adsorption
(
Elsevier B.V.
, 2020 , Article)
Epichlorohydrin crosslinked chitosan/carbon–clay (CSCC) biohybrid adsorbent was prepared for the adsorption of cationic methylene blue (MB) and anionic azo acid blue 29 (AB 29). The 40:60 wt% of chitosan (CS) and carbon–clay ...
Comparative Investigation of the Physicochemical Properties of Chars Produced by Hydrothermal Carbonization, Pyrolysis, and Microwave-Induced Pyrolysis of Food Waste
(
MDPI
, 2022 , Article)
This work presents a comparative study of the physicochemical properties of chars derived by three thermochemical pathways, namely: hydrothermal carbonization, HTC (at 180, 200 and 220 °C), pyrolysis, PY, (at 500, 600 and ...
Adsorption of endocrine disrupting compounds and other emerging contaminants using lignocellulosic biomass-derived porous carbons: A review
(
Elsevier Ltd
, 2020 , Article)
Hydrochars from lignocellulose biomass have received an upsurge of interest in different fields, especially in the area of adsorption. Hydrothermally produced hydrochars are effective adsorbents for removing different ...
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. ...
