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 ...
Pilot-scale spiral wound membrane assessment for THM precursor rejection from upland waters
(
Taylor and Francis Inc.
, 2016 , Article)
The outcomes of a pilot-scale study of the rejection of trihalomethanes (THMs) precursors by commercial ultrafiltration/nanofiltration (UF/NF) spiral-wound membrane elements are presented based on a single surface water ...
Ab initio molecular dynamics study of the interlayer and micropore structure of aqueous montmorillonite clays
(
Elsevier Ltd
, 2015 , Article)
Ab initio molecular dynamics simulations have been performed to gain an understanding of the interfacial microscopic structure and reactivity of fully hydrated clay edges. The models studied include both micropore and ...
Outlook and challenges for hydrogen storage in nanoporous materials
(
Springer Verlag
, 2016 , Article)
Considerable progress has been made recently in the use of nanoporous materials for hydrogen storage. In this article, the current status of the field and future challenges are discussed, ranging from important open ...
Hot electron and hole dynamics in thiol-capped CdSe quantum dots revealed by 2D electronic spectroscopy
(
Royal Society of Chemistry
, 2016 , Article)
Colloidal quantum dots (QDs) have attracted interest as materials for opto-electronic applications, wherein their efficient energy use requires the understanding of carrier relaxation. In QDs capped by bifunctional thiols, ...
Zero-bias photocurrents in highly-disordered networks of Ge and Si nanowires
(
Institute of Physics Publishing
, 2015 , Article)
Semiconducting nanowire (NW) devices have garnered attention in self-powered electronic and optoelectronic applications. This work explores and exhibits, for the first time for visible light, clear evidence of the zero-biased ...
Effect of outdoor temperature on the power-conversion efficiency of newly synthesized organic photosensitizer based dye-sensitized solar cells
(
Elsevier B.V.
, 2018 , Article)
In this work, organic photosensitizer has been synthesized for dye-sensitized solar cells (DSSCs). The solar cells then fabricated have been characterized by photocurrent-voltage characteristics and electrochemical impedance ...
Synthesis of new amines for enhanced carbon dioxide (CO2) capture performance: The effect of chemical structure on equilibrium solubility, cyclic capacity, kinetics of absorption and regeneration, and heats of absorption and regeneration
(
Elsevier B.V.
, 2016 , Article)
This work focused on the synthesis of new tertiary amines by varying the alkyl chain length with/without hydroxyl group in the structure. The effect of chemical structure of newly synthesized tertiary amines; 4-(dimethyl ...
Synthesis of iron oxide nanoparticles to enhance polysulfone ultrafiltration membrane performance for salt rejection
(
Italian Association of Chemical Engineering - AIDIC
, 2017 , Article)
The main target of membrane technologies is to provide better filtration and separation of organic and inorganic substance from water as well as for longer life of the membrane. Iron oxide (α-Fe2O3) nanoparticles (NPs) ...
The impact of mechanically-imposed shear on clogging, fouling and energy demand for an immersed membrane bioreactor
(
MDPIAG
, 2018 , Article)
The impact of the application of mechanically-imposed shear on the propensity for fouling and clogging (or “sludging”—the agglomeration of sludge solids in the membrane channel) of an immersed flat sheet (iFS) membrane ...
