Gamma irradiation of graphene quantum dots with ethylenediamine: Antioxidant for ion sensing
(Elsevier, 2020)
Due to the low consumption of chemicals, the absence of toxic residual side products, the procedure simplicity and time-saving aspects, gamma irradiation offers advantages over the classical chemical protocols. We successfully ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT–IR, 1H and 13C NMR, UV–Vis, and PL spectroscopy. Photophysical properties of the dyes were examined ...
Binding of metal ions and water molecules to nucleic acid bases: The influence of water molecule coordination to a metal ion on water–nucleic acid base hydrogen bonds
(International Union of Crystallography, 2019)
The interactions of nucleic acid bases with non-coordinated and coordinated water molecules were studied by analyzing data in the Protein Data Bank (PDB) and by quantum chemical calculations. The analysis of the data in ...
A CaO/zeolite-based catalyst obtained from waste chicken eggshell and coal fly ash for biodiesel production
(Elsevier, 2020)
The present paper is focused on the development of a new environment-friendly methanolysis catalyst completely
based on waste materials: lignite coal fly ash and chicken eggshells. A novel catalyst based on CaO
supported ...
Significantly improved stabilization of glycoside hydrolases important in food industry by immobilization onto appropriately modified beidellite
(Elsevier, 2024)
Three glycoside hydrolases (α-amylase, xylanase and pullulanase) were immobilized on low-cost, environmentally friendly, easily modified clay rich in beidellite. Modifications included common procedures: Na-exchange, acid ...
Design of an ethidium bromide control circuit supported by deep theoretical insight
(Elsevier, 2023)
We have set-up an electrochemical advanced oxidation process for ethidium bromide (1), based on the Eu-doped MnWO4 (Eu:MnWO4), obtained through a template-driven synthesis, along with developing a suitable monitoring method. ...
Nano-size cobalt-doped cerium oxide particles embedded into graphitic carbon nitride for enhanced electrochemical sensing of insecticide fenitrothion in environmental samples: An experimental study with the theoretical elucidation of redox events
(Elsevier, 2024)
In the present work, a nanocomposite, based on embedding Co-doped CeO2 nanoparticles into graphitic carbon nitride (g-C3N4), was applied to functionalize commercial glassy carbon paste. This is the first application of the ...
Kinetic and thermodynamic compensation phenomena in C3 and C4 energy crops pyrolysis: Implications on reaction mechanisms and product distributions
(Elsevier B.V., 2023)
This work provides insight into possibilities of maximum utilization of C3-C4 energy crops for thermo-chemical conversion (slow pyrolysis) into high value biochemicals, platform chemicals, drop-in fuels and combustible ...
Еmpirical and process-based models predict enhanced beech growth in European mountains under climate change scenarios: a multimodel approach
(Elsevier, 2023)
Process-based models and empirical modelling techniques are frequently used to (i) explore the sensitivity of tree growth to environmental variables, and (ii) predict the future growth of trees and forest stands under ...
