Waste Cotton and Cotton/Polyester Yarns as Adsorbents for Removal of Lead and Chromium from Wastewater
(Journal of Natural Fibers, 2022)
The possibility of using waste cotton and cotton/polyester yarns to remove lead and chromium ions from polluted water was investigated in this work. Structural, morphological, and adsorption properties of yarns were ...
Biodegradable and active zein-gelatin-based electrospun mats and solvent-cast films incorporating sage extract: Formulation and comparative characterization
(Elsevier Ltd., 2023)
This study aimed to develop active, biodegradable materials for food packaging by incorporating sage extract (SE) within a zein-gelatin blend by electrospinning and solvent casting. The fabrication techniques, SE incorporation, ...
Alkali-activated geopolymerization of a low illitic raw clay and waste brick mixture. An alternative to traditional ceramics
(Elsevier Ltd., 2022)
Geopolymerization was investigated as an alternative to traditional ceramic products by developing a more sustainable approach that avoids thermal treatment. The study presents the first known alkali-activation of the raw ...
Cysteine and cerium as green corrosion inhibitors for AA7049: Mixture vs. complexation
(Elsevier Ltd, 2022)
In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures ...
Effect of mechanical activation on carbothermal synthesis and densification of ZrC
(Elsevier Ltd, 2023)
Zirconium carbide ceramics were prepared by carbothermal reduction of ZrO2 and C that were mixed by high-energy ball milling. Powders were milled for times from 0 to 120 min in air. As milling time increased, the surface ...
A review on the role of plasma technology in the nano-finishing of textile materials with metal and metal oxide nanoparticles
(John Wiley and Sons Inc., 2022)
Nano-finishing of textiles with metal and metal oxide nanoparticles (NPs) is relatively simple, but insufficiently efficient binding between the fibers and NPs poses a big problem because of the poor stability of textile ...
Effect of homogenization temperature on microstructure and mechanical properties of Al-Mg-Si alloy containing low-melting point elements
(Elsevier Ltd., 2022)
To evaluate the effect of homogenization conditions on the possible loss of low-melting-point Pb and Bi to the surface in the free-cutting AA6026 alloy, three homogenization regimes were applied: 480 degrees C/12 h, 530 ...
Steroid-based tracing of sewage-sourced pollution of river water and wastewater treatment efficiency: Dissolved and suspended water phase distribution
(Elsevier B.V., 2022)
In this work, the environmental distribution of steroid compounds and the level of sewage-derived contamination were assessed using sterol ratios in the confluence area of two major rivers in the Serbian capital, where raw ...
Antioxidant and cell-friendly Fe2TiO5 nanoparticles for food packaging application
(Elsevier Ltd, 2022)
An emerging technology of active packaging enables prolongation of food shelf life by limiting the oxygen transfer and the reactivity of free radicals, which both destruct food freshness. In this work, Fe2TiO5 nanoparticles ...
Novel eco-friendly initiation system based on vitamin C for energy efficient synthesis of PMAA hydrogel used for delivery of phenolic compounds
(Elsevier B.V., 2023)
This study reports successful free radical synthesis of pH-sensitive hydrogels based on poly(methacrylic acid) (PMAA) by using new green initiation system based on vitamin C and hydrogen peroxide (VC/H2O2). The application ...
