Added-value porous materials for controlled thymol release obtained by supercritical CO2 impregnation process
(Sage Publications Ltd, London, 2019)
This study explores utilization of biodegradable and biocompatible polymers for controlled release of natural bioactive substance. For that purpose, poly(epsilon-caprolactone) (PCL) beads, cellulose acetate (CA) film, and ...
Hybrid acrylic nanocomposites with excellent transparency and hardness/toughness balance
(Elsevier B.V., 2020)
The composite nanofibers were used as reinforcement in acrylic polymer for the overall enhancement of thermo-mechanical properties, adhesion between fibers and matrix, and fracture toughness of the final nanocomposite since ...
In vitro cytotoxicity assessment of intelligent acrylate based hydrogels with incorporated copper in wound management
(Elsevier Science Sa, Lausanne, 2016)
In order to evaluate biological response and potential toxicity prior to clinical use as wound dressing materials, three series of hydrogels, based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), unloaded, with ...
Structural and surface modification of highly ordered alumina for enhanced removal of Pb2+, Cd2+ and Ni2+ from aqueous solution
(Desalination Publ, Hopkinton, 2020)
The adsorption performance of three-dimensionally ordered macroporous (3DOM) alumina doped with iron oxide, and subsequently modified with (3-aminopropyl)triethoxysilane (APTES), FeAl2O3 and FeAl(2)O(3)APTES, was used for ...
Can Fiber-post Placement Reinforce Structurally Compromised Roots?
(Quintessence Publishing Co Inc, Hanover Park, 2020)
Purpose: Immature teeth are characterized by short roots, thin root canal walls, and open apices, which makes them prone to fracture. The aim was to investigate whether fiber-post placement had an influence on the fracture ...
Leaching of metastannic acid from e-waste by-products
(Springer, New York, 2020)
Anode slime and tin precipitate as by-products of the electrorefining (ER) of non-standard anodes obtained after experimental smelting of waste electric and electronic equipment (e-waste), in addition to the base and ...
Resistance to Pit Formation and Pit Growth for Different Tempers of AA2024 Aluminium Alloy in Presence of Benzotriazole
(Korean Inst Metals Materials, Seoul, 2020)
The paper analyses the corrosion behaviour of both naturally and artificially aged AA2024 aluminium alloy in NaCl solution in the presence of the corrosion inhibitor benzotriazole (BTA). The differences between these two ...
Activity Coefficients of the System {yNaCl + (1 – y)Na2HPO4}(aq) at T = 298.15 K Determined by Electromotive Force Measurements
(Pleiades Publishing, 2023)
The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq) were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength fraction was y = (0.3012; 0.4015; ...
Extending waste paper, cellulose and filler use beyond recycling by entering the circular economy creating cellulose-CaCO3 composites reconstituted from ionic liquid
(Springer Science and Business Media B.V., 2022)
Cellulose-fibre lifecycle is severely limited within today’s recycling methodology. Feedstock cellulose and filler abound in products considered uneconomic, unsuitable for standard deinking or too weak for original product ...
