Indium Recovery from Jarosite Pb–Ag Tailings Waste (Part 1)
(MDPI, 2023)
The processing of zinc ore using hydrometallurgical methods leads to the formation and accumulation of a by-product called jarosite, which contains concentrated precious metals. In this study, we propose the recovery of ...
One-Pot Syntheses of PET-Based Plasticizer and Tetramethyl Thiuram Monosulfide (TMTS) as Vulcanization Accelerator for Rubber Production
(MDPI, 2023)
Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained ...
Morphological and Structural Characterization of MgAl2O4 Spinel
(International Institute for the Science of Sintering (IISS), 2023)
Magnesium aluminate has the spinel structure along with good mechanical, chemical, and thermal properties. Magnesium aluminate has a wide range of applications including refractory ceramics, optically transparent ceramic ...
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 ...
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 ...
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 ...
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 ...
Possibility of Using Vitreous Enamel Waste in the Construction Industry as the Concept of Cleaner Production
(MDPI, 2023)
Waste vitreous enamels from the heating device production process were used for partial replacement of cement in the mortar and concrete production industry. This waste, due to the high content of heavy metals, is classified ...
Optical switching of bent-core liquid crystals with azocinnamoyl units
(Taylor and Francis Ltd., 2023)
We report on observations of optical switching in bent-core liquid crystals possessing azocinnamoyl groups in both elongated side arms. UV-activated switching was observed in two of the synthesised materials, both of which ...
The Removal of Phosphate from Aqueous Solutions by Sepiolite/ZrO2 Composites: Adsorption Behavior and Mechanism
(MDPI, 2023)
The sepiolite/ZrO2 composites were prepared by sepiolite (Sep) modification with zirconium propoxide in toluene at room temperature for 24 h (Sep–ZrI) or 95 °C for 4 h (sample Sep–ZrII). The efficiency of the obtained ...
