A novel hydrogen liquefaction process using dual mixed cryogenic refrigeration system: Energy, exergy, and economic analysis
(
Elsevier
, 2024 , Article)
In conventional hydrogen liquefaction plants, the liquefaction process consumes high portion of about 30 % of the liquid hydrogen (LH2) energy content. In addition, existing LH2 technology uses pure or single mixed ...
Self-standing foam-like Pd-based alloys nanostructures for efficient electrocatalytic ethanol oxidation
(
Elsevier
, 2023 , Article)
In this work, self-standing binary porous PdM (M = Ni, Fe and Co) foam-like nanostructures are rationally designed by a rapid and one-step aqueous-solution method, including ice co-reduction of metal precursors using sodium ...
Development of Inorganically Cross-Linked Sulfonated Polyacrylamide Preformed Particle Gels for Conformance Control: Impact of Anionic Groups
(
American Chemical Society (ACS)
, 2024 , Article)
Modern oil and gas extraction faces challenges, notably from the surplus of produced water, hampering hydrocarbon recovery and raising environmental and economic concerns. A promising solution is the injection of preformed ...
An Investigation of the Swelling Kinetics of Bentonite Systems Using Particle Size Analysis
(
Taylor and Francis Inc.
, 2019 , Article)
Particles size distribution (PSD) is introduced as a tool for analysis of bentonite aggregation and swelling kinetics. Raw Ca-bentonite was purified using a combined wet sieving and sedimentation processes, followed by ...
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 ...
Photostability of the Oleic Acid-Encapsulated Water-Soluble CdxSeyZn1-xS1-y Gradient Core-Shell Quantum Dots
(
American Chemical Society
, 2017 , Article)
Composite systems where quantum dots (QDs) are combined with other nanomaterials (e.g., gold nanorods) in aqueous solutions have attracted broad attention - both for their potential in applications and for studies of ...
Enhanced electrochemical conversion of CO2 into formic acid using PbSO4/AtSn electrode: Catalyst synthesis and process optimization
(
Elsevier
, 2023 , Article)
Electrochemical carbon dioxide (CO2) reduction is among the most promising and effective methods for producing valuable fuels while simultaneously addressing global warming. Numerous metal-based materials showed promising ...
Clay minerals damage quantification in sandstone rocks using core flooding and NMR
(
Springer Verlag
, 2019 , Article)
Sandstone oil reservoirs consist of different clay minerals such as kaolinite, illite, and chlorite. These clay minerals highly affect the formation damage during enhanced oil recovery (EOR) and well stimulation operations ...
Active and stable methane oxidation nano-catalyst with highly-ionized palladium species prepared by solution combustion synthesis
(
MDPI AG
, 2018 , Article)
We report on the synthesis and testing of active and stable nano-catalysts for methane oxidation. The nano-catalyst was palladium/ceria supported on alumina prepared via a one-step solution-combustion synthesis (SCS) method. ...
Optimization of a combined approach for the treatment of carbide slurry and capture of CO2
(
Science Publications
, 2016 , Article)
The aim of this study is to evaluate the potential use of electrocoagulation in the treatment of carbide slurry, a wastewater generated during the production of acetylene, and in the capture of carbon dioxide. An electrochemical ...
