Foam glasses made from green bottle glass and sugar beet factory lime as a foaming agent
(Elsevier Ltd., 2023)
Great waste production alongside limited natural resources represents huge environmental and economic problems worldwide. Sustainable waste management and industrial production can reduce pollution and gain some economic ...
2 in 1 versus 1 plus 1 – Outcomes of the transformation of adsorptive stripping method for the Ni2+ and Co2+ determination
(John Wiley and Sons Inc., 2023)
Due to the similar chemical properties of Ni2+ and Co2+, several dozens of adsorptive stripping voltammetric (AdSV) methods have been developed for their simultaneous determination. The question was would there be some ...
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 ...
Potential of organic carbonates production for efficient carbon dioxide capture, transport and storage: Reaction performance with sodium hydroxide–ethanol mixtures
(Elsevier Ltd, 2023)
Carbon dioxide storage is one of the main long-term strategies for reducing carbon dioxide emissions in the atmosphere. A clear example is Norway's Longship project. If these projects should succeed, the transport of huge ...
Cerium citrate as ecologically friendly corrosion inhibitor for AA7075 alloy
(Materials and Corrosion-Werkstoffe Und Korrosion, 2022)
The corrosion behaviour of high-strength AA7075 aluminium alloy in NaCl solution, without and in the presence of environmentally friendly corrosion inhibitors (Ce-chloride and Ce-citrate) in low concentrations ( lt 0.5 ...
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, ...
Clinoptilolite—An Efficient Carrier for Catalytically Active Nano Oxide Particles
(MDPI, 2023)
Many efforts have been devoted to produce green materials and technology to prevent and minimize the adverse effects on the environment and human health caused primarily by population growth and industrial progress. Over ...
Deep Eutectic Solvent Based Reversed-Phase Dispersive Liquid–Liquid Microextraction and High-Performance Liquid Chromatography for the Determination of Free Tryptophan in Cold-Pressed Oils
(MDPI, 2023)
A fast and straightforward reversed-phase dispersive liquid–liquid microextraction (RP-DLLME) using a deep eutectic solvent (DES) procedure to determine free tryptophan in vegetable oils was developed. The influence of ...
Statistical methods for designing a Geiger–Muller counter suitable for an early warning system
(Elsevier B.V., 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
