Carbon Microrod Material Derived from Human Hair and Its Electrochemical Supercapacitor Application
(Gazi Üniversitesi, 2021)
Here, Turkish human hair fibers were used as a carbon source at the synthesis of human hair-sourced activated carbons (HHC). During the synthesis of HHCs sodium carbonate (Na2CO3) was added to the synthesis process for an ...
Synthesis, characterization, and antioxidant and anticholinesterase activities of pyrazolo derivatives
(Wiley, 2020)
Twenty-four pyrazolo derivatives (1-4)(a-f) were synthesized and characterized by FTIR, H-1, and C-13 NMR (Nuclear Magnetic Resonance), and elemental analysis. The synthesized compounds were also investigated for their ...
Development and application of a SARS-CoV-2 colorimetric biosensor based on the peroxidase-mimic activity of γ-Fe 2 O 3 nanoparticles
(Springer, 2021)
A practical colorimetric assay was developed for the detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this purpose, magnetic γ Fe2O3 nanoparticles were synthesized and used as a peroxidase-like ...
Chemical composition, antioxidant and anticholinesterase activity of the essential oil of algerian cachrys sicula L
(Taylor and Francis Ltd., 2021)
In this work, in order to explore a new Algerian medicinal plant used in traditional medicine, the essential oil of the leaves of Cachrys sicula L. (Apiaceae) collected from Algeria, obtained by hydrodistillation, was ...
Evaluation of Enzyme Inhibition and Anti-Quorum Sensing Potentials of Melaleuca alternifolia and Citrus sinensis Essential Oils
(SAGE PUBLICATIONS, 2021)
In this study, Melaleuca alternifolia (Maiden and Betche) Cheel (tea tree) oil and C. sinensis (L.) Osbeck (orange) oil was procured, and their chemical compositions were characterized by gas chromatography coupled with ...
Bioaccumulation and health risk assessment of heavy metals in European eels taken from Lakes Köyceğiz (Turkey) and Võrtsjärv (Estonia)
(Springer Science and Business Media Deutschland GmbH, 2021)
Monitoring heavy metal contaminants in fish is important for the assessment of environmental quality as well as food safety. In this study, European eel samples were collected from Lake Köyceğiz and Lake Võrtsjärv in 2017 ...
Determination of radioactivity levels in feldspathic dental ceramics
(Elsevier, 2021)
Activity concentrations of 42 different feldspathic dental ceramic powders were determined using a gamma spectrometer with an HPGe detector. The average 238U, 232Th and 226Ra activity concentrations of the specimens were ...
Centri-Voltammetric GSH Detection with PDI-C4SH as a Carrier Material
(John Wiley and Sons Inc, 2021)
In this study, we developed a centri-voltammetric electrochemical sensor for glutathione (GSH) detection. For this purpose, N,N′-2-octyloxy-1-methyl-2-oxoethyl)-(-2,4-thiolbutyloxy)-1-methyl-2-oxoethyl)-3,4 : 9,10-peryle ...
Volatile compound profile and essential oil composition of three wild Algerian aromatic plants with their antioxidant and antibiofilm activities
(SPRINGER, 2021)
Aromatic plants represent a natural source of bioactive compounds. Even their essential oils attracted the interesting of many researchers for their biological activities. Therefore, the aims of this work were to analyze ...
An impedimetric approach for COVID-19 detection
(ROYAL SOC CHEMISTRY, 2021)
In this study, an electrochemical approach for the determination of coronavirus disease (COVID-19) was developed. The biosensor system relied on the spike protein (S-protein) based infection mechanism of the virus and ...
