Experimental examination and thermodynamic description of the ternary Bi-Ge-Ga,Zn systems
(Elsevier, 2020)
Due to the wide application of systems based on germanium ternary Bi-Ga-Ge and Bi-Ge-Zn systems were experimentally tested in this study. Used experimental techniques were scanning electron microscope with energy dispersive ...
Photocatalytically active Ag-doped TiO2 coatings developed by plasma electrolytic oxidation in the presence of colloidal Ag nanoparticles
(Elsevier, 2024)
The plasma electrolytic oxidation process of Ti foil in the presence of a colloidal solution of Ag nanoparticles was used for the synthesis of exceptionally photocatalytically active Ag-doped TiO2 coatings. UV–Vis absorption ...
A new small-celled naviculoid diatom species, Mayamaea pannonica sp. nov. (Bacillariophyceae) from soda pans in Serbia
(Taylor & Francis, 2023)
Combining morphological and molecular approaches, a new diatom species is described in the genus Mayamaea from a Special Nature Reserve, Okanj bara in Serbia, an alkaline and subsaline soda pan with pronounced seasonal ...
Solid-state silica gel-catalyzed synthesis of fluorescent polysubstituted 1,4- and 1,2-dihydropyridines
(Great Britain : Royal Society of Chemistry, 2023)
We present the green, highly atom-economical, solid-state silica gel-catalyzed synthesis of polysubstituted
1,4- and 1,2-dihydropyridines (DHPs) from commercially available materials, amines and ethyl propiolate.
The DHP ...
Assessment of waste hop (Humulus Lupulus) stems as a biosorbent for the removal of malachite green, methylene blue, and crystal violet from aqueous solution in batch and fixed-bed column systems: Biosorption process and mechanism
(Elsevier, 2024)
The discharge of industrial textile waters into water bodies leads to the accumulation of pollutants which are a serious threat to humans and the environment. The development of an efficient adsorbent for the removal of ...
Binding symmetric porphyrins to the c-MYC promoter Pu24I G-quadruplex: toward more specific ligand recognition by flanking bases
(Royal Society of Chemistry (RSC), 2023)
Stabilization of G-quadruplexes formed in the promoter regions of oncogenes with small molecules is recognized as a convenient method to control oncogenes’ overexpression in cancer cells. Due to a huge number of potential ...
A comparative study on X-ray peak broadening analysis of mechanically alloyed Al2O3 particles dispersion strengthened Al 7017 alloy
(Elsevier, 2023)
AA7017 + x vol. % Al2O3 (x = 5, 10, 20) nanocomposites powders were synthesized by HEBM process with milling time of 0 h and 20 h. The synthesized nanocomposite powders were characterized using XRD (Bruker USA D8 Advance, ...
A universal transportation model for reverse osmosis systems
(Elsevier, 2021)
This paper presents a new transport model for reverse osmosis (RO) systems, which combines irreversible thermodynamics, together with solution-diffusion theory. The simplifications adopted by the classical theory for ...
Triplet state (anti)aromaticity of some monoheterocyclic analogues of benzene, naphthalene and anthracene
(Royal Society of Chemistry, 2021)
Aromaticity–antiaromaticity switch upon singlet–triplet transition of some biologically and synthetically
important monoheterocycles (heteroatom = N, O, Si, P, and S) derived from benzene, naphthalene and
anthracene was ...
Comparative Study of the Essential Oil and Hydrosol Composition of Sweet Wormwood (Artemisia annua L.) from Serbia
(Wiley, 2022)
The most abundant volatile compounds of sweet wormwood (Artemisia annua L.) essential oil were artemisia ketone (25.4 %) and trans-caryophyllene (10.2 %), followed by 1,8-cineole, camphor, germacrene D and β-selinene. The ...
