(Elsevier Inc., 2023)To reduce the progression of the viral process in patients infected with COVID-19, new treatments and drug active substances are needed. One of these drugs is Molnupiravir (MNP) which has a direct antiviral effect and has ... -
Semi-detached Algol type binaries with increasing orbital periods: Case studies of BD Vir, BO Gem, DG Lac, RW Cet, and RX Hya
(Elsevier B.V., 2023)This paper presents results from photometric investigations of five semi-detached binaries. Using the TESS and KEPLER (K2) databases, light curves of classical Algol systems BD Vir, BO Gem, DG Lac, RW Cet, and RX Hya were ... -
A novel electrochemical biosensor based on palladium nanoparticles decorated on reduced graphene oxide-polyaminophenol matrix for the detection and discrimination of mitomycin C-DNA and acyclovir-DNA interaction
(Elsevier B.V., 2023)Both the design of molecules that will interact specifically with DNA and the determination of the mechanism of action of this drug on DNA are important as they allow the control of gene expression. In particular, rapid ... -
Removal of Cd(II), Co(II), Cr(III), Ni(II), Pb(II) and Zn(II) ions from wastewater using polyethyleneimine (PEI) cryogels
(Academic Press, 2023)The removal of the target analytes, Cd(II), Co(II), Cr(III), Ni(II), Pb(II), and Zn(II) from contaminated waters was achieved using super porous polyethyleneimine (PEI) cryogels as adsorbent. The optimum values of the ... -
Generalized complete orthonormal sets of Exponential-Type functions
(Elsevier B.V., 2023)New generalized complete orthonormal sets of ψα-exponential type functions are described and applied to LCAO calculations for the total energies of atomic systems within the framework of the minimal basis sets approximation ... -

Investigation of the teleparallel energy momentum problem for Texture metric
(Elsevier B.V., 2023)In this paper we have investigated Einstein (E), Bergmann–Thomson (BT) and Landau–Lifshitz (LL) energy–momentum distributions for Texture metric in Teleparallel gravitation (TG) theory. Although these energy–momentum ... -
The electrical and photophysical performances of axially-substituted naphthalene diimide-based small molecules as interface layer
(Elsevier Ltd, 2023)To date, the number of publications on NDI-based small molecules is almost identical to the number of publications on NDI-based polymers. As opposed to the polymer examples, the design of NDI-based small molecules can be ... -
Precarcinogens in food – Mechanism of action, formation of DNA adducts and preventive measures
(Elsevier Ltd, 2023)Food quality and food composition play key roles in human health. Food may contain harmful ingredients apart from the basic ingredients beneficial to our body. A harmful group of substances entering food from the environment ... -
