Analysis of the Mechanism of Acid Mine Drainage Neutralization Using Fly Ash as an Alternative Material: A Case Study of the Extremely Acidic Lake Robule in Eastern Serbia
(MDPI, 2022)
Acid mine drainage (AMD) is a waste from mining sites, usually acidic, with high concentrations of sulfates and heavy metal ions. This study investigates the AMD neutralization process using fly ash (FA) as an alternative ...
Oxidized jute as a valuable adsorbent for Congo Red from an aqueous solution
(SAGE Publications Ltd., 2022)
The raw jute fabric was oxidized with 0.2% or 0.4% NaIO4 for 60 or 120 min to obtain valuable adsorbents for the textile dye Congo Red (CR). Batch adsorption experiments were carried out as a function of solution pH, contact ...
TiO2 nanotubes film/FTO glass interface: Thermal treatment effects
(ETRAN, 2022)
Pure Ti films deposited by radio-frequency magnetron sputtering on FTO glass were anodized to fabricate TiO2 nanotubes (NTs) arrays. The TiO2 NTs/FTO samples were sintered at 450, 550 and 630°C, in ambient air. The thermal ...
Influence of pilling on the quality of flax single jersey knitted fabrics
(SAGE Publications Ltd, 2022)
In this work, the quality of four plain single jersey weft-knitted fabrics (produced from the same flax yarn) having different structural characteristics (stitch density, weight, and thickness) before and after pilling, ...
Achieving a Superhydrophobic, Moisture, Oil and Gas Barrier Film Using a Regenerated Cellulose–Calcium Carbonate Composite Derived from Paper Components or Waste
(MDPI, 2022)
It has been a persistent challenge to develop eco-friendly packaging cellulose film providing the required multiple barrier properties whilst simultaneously contributing to a circular economy. Typically, a cellulosic film ...
The Design of a System for the Induction Hardening of Steels Using Simulation Parameters
(MDPI, 2023)
This paper presents the development of a piece of induction hardening equipment based on the foundations of the design, starting from zero. It was intended for steels in general, and was tested on unalloyed low- and ...
Kinetic Model for Galacto-Oligosaccharide Synthesis
(American Chemical Society, 2022)
A new micro-kinetic model is proposed for galacto-oligosaccharide (GOS) synthesis with β-galactosidase from Aspergillus oryzae. Several kinetic models with similar reaction mechanisms, i.e., steps and kinetic constants, ...
Selection of processing parameters for the integrated supercritical CO2 extraction from green tea leaves and extract impregnation onto starch-chitosan based films
(Elsevier B.V., 2024)
The study aimed toward the development of biocompatible and biodegradable polymeric films (starch-chitosan and starch-chitosan-cyclodextrin) with biologically valuable green tea leaf extract using an environmentally friendly ...
Optimization of Enzymatic Desizing and Scouring of Cotton Fabric by Response Surface Methodology
(Publishing House of the Romanian Academy, 2023)
The study aimed to estimate the influence of temperature, time, and ultrasound application during desizing and scouring of cotton with α-amylase and pectinase, respectively, on the weight loss, breaking force and color ...
Exposure Factors in Health Risk Assessment of Heavy Metal(loid)s in Soil and Sediment
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Heavy metal(loid)s (HMs) play an important role in economic development since they are used in various branches of industry. However, all industrial activities emit HMs into the environment, where they are no longer useful ...
