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 ...
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, ...
Structure-Dependent Electrochemical Behavior of 2-Pyridone Derivatives: A Combined Experimental and Theoretical Study
(MDPI, 2023)
In this work, the electrooxidation ability of nine pyridones was evaluated using cyclic(CV) and square-wave voltammetry (SWV) in Britton–Robinson (BR) aqueous buffer solutions on aglassy carbon electrode (GC). The dependence ...
The surprising discovery of two new subterranean Leptodirini of the genus Spelaeobates Müller, 1901 (Coleoptera, Leiodidae, Cholevinae) from Croatia after more than a century
(Pensoft Publishers, 2023)
Two new subterranean leiodid taxa of the genus Spelaeobates Müller, 1901 from three pits in northern Dalmatia (Croatia), S. coriniensis sp. nov. and S. coriniensis nonveilleri ssp. nov., are described. The morphological ...
Eco‑friendly dyeing of polyamide and polyamide‑elastane knits with living bacterial cultures of two Streptomyces sp. strains
(Springer Science and Business Media, 2023)
Given the environmental burden of textile industry, especially of dyeing processes and the volume of synthetic dyes and surfactants, the intensive development of the greener approaches is under way. Herein, an environmen ...
Black Pine (Pinus nigra) Essential Oil as a Green Corrosion Inhibitor for Carbon Steel
(MDPI, 2023)
In this work, the essential oil of black pine (Pinus nigra J. F. Arnold) was used for the first time as a natural, ecological, and sustainable corrosion inhibitor for the acid cleaning of carbon steel. The essential oil ...
Revalorization of Cotton and Cotton/Elastane Knitted Fabric Waste
(Korean Fiber Society, 2023)
The present paper demonstrates a simple way for revalorization of differently softened cotton and cotton/elastane knitted fabric waste collected from the textile industry. Such waste was used as an adsorbent for Congo Red ...
Mechanical properties of acrylate matrix composite reinforced with manganese-aluminum layered double hydroxide
(John Wiley and Sons Inc., 2023)
Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double ...
Mechanical Properties of Electrolytically Produced Copper Coatings Reinforced with Pigment Particles
(MDPI, 2023)
Copper from sulfate baths without and with added inorganic pigment particles based on strontium aluminate doped with europium and dysprosium (SrAl2O4: Eu2+, Dy3+) was electrodeposited on a brass cathode by a galvanostatic ...
Antimicrobial and UV protective chitosan/lignin multilayer nanocoating with immobilized silver nanoparticles
(John Wiley and Sons Inc., 2023)
Poor antimicrobial activity and lack of protection against UV irradiation are weaknesses of cotton textiles. In an attempt to impart superior antimicrobial and UV-protective properties to cotton, layer-by-layer deposition ...
