A new process for the recovery of ammonia from ammoniated high-salinity brine
(
MDPI
, 2021 , Article)
This paper describes a new method for the recovery of high-concentration ammonia from water in the form of ammonium chloride, ammonium hydroxide and ammonium carbonate. The method was applied to the Solvay process, in which ...
Ion-imprinted membranes for lithium recovery: A review
(
Elsevier
, 2024 , Article)
This review critically examines the effectiveness of ion-imprinted membranes (IIMs) in selectively recovering lithium (Li) from challenging sources such as seawater and brine. These membranes feature customized binding ...
Drastic difference between hole and electron injection through the gradient shell of Cd: XSeyZn1- xS1- y quantum dots
(
Royal Society of Chemistry
, 2017 , Article)
Ultrafast fluorescence spectroscopy was used to investigate the hole injection in CdxSeyZn1−xS1−y gradient core–shell quantum dot (CSQD) sensitized p-type NiO photocathodes. A series of CSQDs with a wide range of shell ...
A comparison of the redox properties of vanadia-based mixed oxides
(
American Chemical Society (ACS)
, 2015 , Article)
The thermodynamics of oxidation and reduction were investigated for a series of vanadium-containing oxides, including CeVO4, LaVO 4, ZrV2O7, Mg3(VO4) 2, CrVO4, AlVO4, and V2O 5, in the temperature range between 873 and 973 ...
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 ...
