A closed cycle of sustainable development: Effective removal and desorption of lead and dyes using an oxidized cellulose membrane
(Elsevier B.V., 2023)
Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linters
cross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystal
violet (CV) ...
Sr,Mg co-doping of calcium hydroxyapatite: Hydrothermal synthesis, processing, characterization and possible application as dentin substitutes
(Ceramics International, 2022)
The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) ...
Polypyrrole on graphite: An exemplary model system for comprehensive electrochemical analysis of energy storage materials
(Elsevier BV, 2023)
Electrochemical Energy Storage (EES) technologies are playing a significant role in the aspirations to decrease the usage of fossil fuels and move toward an environmentally conscious society. Due to the importance of EES ...
A new group contribution model for prediction liquid hydrocarbon viscosity based on free-volume theory
(Elsevier B.V., 2023)
In this paper a group contribution model for predicting the viscosity values of n-alkanes and iso-alkanes in the liquid phase based on Free-Volume Theory was developed. A database with 2129 experimental data with a temperature ...
Recovery of bioactive molecules from Hypericum perforatum L. dust using microwave-assisted extraction
(Springer Science and Business Media Deutschland GmbH, 2024)
Microwave-assisted extraction (MAE) conditions were optimized to improve extract quality of medicinal herb — Hypericum perforatum L. (St. John’s wort) dust. Response surface methodology was applied initially to obtain the ...
Activation of Osmium by the Surface Effects of Hydrogenated TiO2 Nanotube Arrays for Enhanced Hydrogen Evolution Reaction Performance
(American Chemical Society, 2023)
Efficient cathodes for the hydrogen evolution reaction (HER) in acidic water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to achieve economically viable operation, both the content of ...
Lignin based microspheres for effective dyes removal: Design, synthesis and adsorption mechanism supported with theoretical study
(Academic Press, 2023)
Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier B.V., 2023)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy-dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined, ...
Exploring the supramolecular profile of 5-phenylhydantoins
(Royal Society of Chemistry, 2023)
The present study describes representative examples of supramolecular arrangement of 5-phenylhydantoins achieved through various N-H⋯O hydrogen-bonding patterns. Four derivatives, 5-ethyl-5-(4-methylphenyl)hydantoin (1) ...
Selective laser sintered Pipe Ring Notched Tension specimens for examination of fracture properties of pipeline materials
(Elsevier Ltd., 2023)
In order to develop a non-standard method for determining the resistance to fracture and damage of pipeline materials, a new geometry of ring-shaped specimens with sharp notches or cracks has been defined. The need to ...
