Study on thermal stability of water-based polyurethanes derived from hydroxypropyl terminated poly(dimethylsiloxane)
(Springer Science and Business Media B.V., 2024)
In this paper, thermal and thermo-oxidative stability of three water-based polyurethanes (PUs) derived from hydroxypropyl terminated poly(dimethylsiloxane) (HPT-PDMS) were studied. The structural properties of the synthesized ...
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, ...
Recovery of Rare Earth Elements from Coal Fly and Bottom Ashes by Ultrasonic Roasting Followed by Microwave Leaching
(MDPI, 2024)
Considering the rising demand for rare earth elements (REEs), researchers are looking for new sources for their extraction, thereby fostering economic and environmentally justified processing solutions. Among potential ...
Ability of Deep Eutectic Solvent Modified Oat Straw for Cu(II), Zn(II), and Se(IV) Ions Removal
(MDPI, 2023)
In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the ...
Occurrence, Source Apportionment, and Health Risk Assessment of Polycyclic Aromatic Hydrocarbons in Soil of Urban Parks in a Mid-Sized City
(Institute for Ionics, 2023)
Public parks and open playgrounds are the most important compartments of the urban environment due to their role in sustaining the well-being of city residents, primarily through relaxation and recreation. To determine the ...
Synthesis of novel pyridinium based compounds and their possible application in dye-sensitized solar cells
(Elsevier B.V., 2023)
Five novel D-π-A structured pyridinium based compounds, bearing different electron-donating units were synthesized, minutely characterized, and their solvatochromic and electronic properties were investigated. Subsequently, ...
Radiological and Structural Characterization of Raw and Alkali-Activated Wood Ash and Metakaolin Blends
(MDPI, 2022)
The aim of the presented research was to investigate the application possibility of wood ash and metakaolin to obtain alkali-activated materials as relatively new materials in the building industry. Thus, in order to assess ...
Thermodynamic Properties of Caffeine in Ethylene Glycol at High Pressures and High Temperatures
(American Chemical Society, 2022)
Ethylene glycol is recognized as a heat transfer fluid. To improve its performance, caffeine is added to pure ethylene glycol. The experimental measurements of densities at pressures of up to 60 MPa and in the range of ...
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 ...
Reduction of fines in recycled paper white water via cellulase enzymes
(North Carolina State University, 2024)
Due to the high wastepaper recyclability and water-loop system closure, packaging paper mills struggle with increased fines, causing runnability issues. Cellulase enzymes are a preferred treatment choice for the improvement ...
