Acetylation of cellulose – Another pathway of natural cellulose aging during library storage of books and papers
(Elsevier Ltd, 2022)
Gaseous acetic acid is formed under conditions of storage of historic paper objects. Its presence not only promotes hydrolytic cleavage of cellulose, but also causes acetylation of the cellulosic material to very small ...
Effect of chemical modifications and coating with Cu-based nanoparticles on the electro-physical properties of jute fabrics in a condition of high humidity
(Elsevier B.V., 2022)
The electro-physical properties of raw, alkali and oxidatively modified jute fabrics were investigated as complex phenomena of the interactions between the fabrics’ chemical composition, carboxyl group content, crystallinity, ...
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 ...
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 ...
The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper
(Journal of Natural Fibers, 2022)
This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use ...
Investigation of seasonal variations and multiple fuel options in a novel tri-generation CSP integrated hybrid energy process
(Elsevier Ltd, 2022)
This work presents a novel Mixed-Integer Non-linear Program (MINLP) that accounts for the presence of multiple fuels in tri-generation systems. The key novelty of this work pertains to the use of hybrid energy systems in ...
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 ...
Removal of trivalent chromium from aqueous solutions by natural clays: Valorization of saturated adsorbents as raw materials in ceramic manufacturing
(Elsevier, 2023)
Kaolinite/illite (KUb) and sepiolite (SEP) clays were used to study Cr(III) adsorption removal from aqueous solutions so that they could be utilized after saturation for ceramic manufacturing. SEP had a larger specific ...
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 ...
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, ...
