Corrosion behavior of AA2024-T6 and AA6065-T6 alloys in reline
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
Deep eutectic solvents have been widely acknowledged as ionic liquid analogues, since they share many characteristics and properties with ionic liquids. The two major application areas of deep eutectic solvents have been ...
Thermo-oxidative evolution and physico-chemical characterization of seashell waste for application in commercial sectors
(Elsevier, Amsterdam, 2020)
Thermo-oxidative degradation of mollusk shells to CaO through intermediate phase of CaCO3 has been investigated using various analytical techniques. Powders of shells species (Dosinia exoleta and Ostrea edulis), with ...
The influence of different extraction conditions on polyphenol content, antioxidant and antimicrobial activities of wild thyme
(Journal of Applied Research on Medicinal and Aromatic Plants, 2021)
The aims of the presented study were the investigation of the effect of different ultrasound-assisted extraction conditions (particle size, solid-to-solvent ratio, ethanol concentration and time) on polyphenol and flavonoid ...
Reactor conceptual design by optimization for hydrogen production through intensified sorption- and membrane-enhanced water-gas shift reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2020)
In this feasibility study, a novel industrial-scale reactor structure for continuous hydrogen production via intensified water-gas shift (WGS) reaction is proposed. It considers both trickling calcium-oxide sorbent for ...
Tetragonal CoMn2O4 nanocrystals on electrospun carbon fibers as high-performance battery-type supercapacitor electrode materials
(Royal Society of Chemistry, 2021)
We herein report a simple two-step procedure for fabricating tetragonal CoMn2O4 spinel nanocrystals on carbon fibers. The battery-type behavior of these composite fibers arises from the redox activity of CoMn2O4 in an ...
Volumetric and thermodynamic properties of binary mixtures of p-cymene with alpha-pinene, limonene and citral at atmospheric pressure and temperatures up to 323.15 K
(Journal of Molecular Liquids, 2021)
An experimental analysis of density, refractive index, speed of sound and the viscosity at atmospheric pressure and temperatures T = (288.15 to 323.15) K has been carried out for the three binary systems, i.e. (p-cymene + ...
New Theoretical Insight into Fluorination and Fluorine-Fluorine Interactions as a Driving Force in Crystal Structures
(Amer Chemical Soc, Washington, 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F center dot center dot center dot F interactions ...
A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier Sci Ltd, Oxford, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO supported ...
Potential application of low molecular weight excipients for amorphization and dissolution enhancement of carvedilol
(International Journal of Pharmaceutics, 2021)
In this study, four low molecular weight (LMW) excipients, tryptophan (TRY), phenylalanine (PHE), lysine (LYS) and saccharin (SAC) were evaluated as co-formers to generate co-amorphous systems (CAMS) by ball milling with ...
Hydrothermal carbonization of spent mushroom substrate: Physicochemical characterization, combustion behavior, kinetic and thermodynamic study
(Journal of Analytical and Applied Pyrolysis, 2021)
Hydrothermal carbonization (HTC) was employed for the conversion of the spent mushroom substrate (SMS) into a carbonaceous hydrochar. The effect of operating temperature (180, 200, 220, 240, and 260 ?C) on the physicochemical, ...
