A critical review of CO2 photoconversion: Catalysts and reactors
(2014 , Article)
Photocatalytic conversion of CO2 to either a renewable fuel or valuable chemicals, using solar energy has attracted more and more attention, due to the great potential to provide an alternative clean fuel and solve the ...
Synthesis Of Transition Metal Nanoparticles Using Combustion Based Techniques
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference Paper)
Solution combustion synthesis (SCS) is a widely used technique for synthesizing variety of high purity oxide nanoparticles. Two basic modes for combustion synthesis are the self-propagating high temperature synthesis (SHS) ...
Oxygen reduction reaction catalysts used in microbial fuel cells for energy-efficient wastewater treatment: A review
(
Royal Society of Chemistry
, 2016 , Other)
Microbial fuel cells (MFCs) as an energy-efficient wastewater treatment technology have attracted increasing interest in the past decade. Cathode catalysts for the oxygen reduction reaction (ORR) present a major challenge ...
When bioelectrochemical systems meet forward osmosis: Accomplishing wastewater treatment and reuse through synergy
(
MDPI AG
, 2015 , Other)
Bioelectrochemical systems (BES) and forward osmosis (FO) are two emerging technologies with great potential for energy-efficient water/wastewater treatment. BES takes advantage of microbial interaction with a solid electron ...
Bioremediation of Crude Oil Contaminated Desert Soil: Effect of Biostimulation, Bioaugmentation and Bioavailability in Biopile Treatment Systems
(
MDPI AG
, 2016 , Article)
This work was aimed at evaluating the relative merits of bioaugmentation, biostimulation and surfactant-enhanced bioavailability of a desert soil contaminated by crude oil through biopile treatment. The results show that ...
Bioelectrochemical production of hydrogen in an innovative pressure-retarded osmosis/microbial electrolysis cell system: experiments and modeling
(
BioMed Central
, 2015 , Article)
Background
While microbial electrolysis cells (MECs) can simultaneously produce bioelectrochemical hydrogen and treat wastewater, they consume considerable energy to overcome the unfavorable thermodynamics, which is not ...
Investigation of Ester- and Amide-Linker-Based Porous Organic Polymers for Carbon Dioxide Capture and Separation at Wide Temperatures and Pressures
(
American Chemical Society
, 2016 , Article)
Organic compounds, such as covalent organic framework, metal–organic frameworks, and covalent organic polymers have been under investigation to replace the well-known amine-based solvent sorption technology of CO2 and ...
Evolution of Seawater Desalination and Petroleum Refinery Wastewater Treatment in a Microbial Desalination Cell
(
Hamad bin Khalifa University Press (HBKU Press)
, 2016 , Conference Paper)
Petroleum refining, not only consumes large quantities of water but also generates large quantities of wastewater. Large quantities of petroleum refinery wastewater are generated worldwide, approximately 3.5-5 m3 of ...
Anomalous manganese activation of a pyrophosphate cathode in sodium ion batteries: A combined experimental and theoretical study
(2013 , Article)
Sodium ion batteries (SIBs) have many advantages such as the low price and abundance of sodium raw materials that are suitable for large-scale energy storage applications. Herein, we report an Mn-based pyrophosphate, ...
Production of sensitive gas sensors using CuO/SnO2 nanoparticles
(
Springer Verlag
, 2019 , Article)
Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating ...
