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 ...
In vitro hypoglycemic, antioxidant and antineurodegenerative activity of chokeberry (Aronia melanocarpa) leaves
(Elsevier, 2020)
Chokeberries (Aronia melanocarpa (Michx.) Elliot have recently become one of the most popular and widely used berry fruits, and there are numerous studies dealing with the investigation of their chemical composition and ...
Activation of Oxone® with plasma deposited mixed cobalt and alumina oxide for the dye degradation
(Elsevier, 2020)
The aim of this work is to examine the possibility of the formation of cobalt doped Al2O3 coatings on aluminum substrate by plasma electrolytic oxidation process (PEO) and application of the obtained material as catalyst ...
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 ...

Oxidative degradation of aromatic N-compounds using cobalt containing montmorillonite-based catalysts
(Elsevier, 2020)
The goal of this work was the synthesis of a montmorillonite based catalyst for advanced oxidative degradation of organic water pollutants. Montmorillonite (Mt) –rich bentonite was acid-activated (MtA), and impregnated ...
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 ...
Aluminum-based self-powered hyper-fast miniaturized sensor for breath humidity detection
(Elsevier, 2020)
An aluminum-based, self-powered, miniaturized sensor for breath humidity detection is presented. The sensor is designed as an interdigitated capacitor made out of sputtered aluminum 1 % silicon (Al 1 %Si) thin film, 700 ...
