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 ...
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 ...
The effect of two types of dibenzoannulation of pentalene on molecular energies and magnetically induced currents
(Royal Society of Chemistry, 2019)
The effect of two types of dibenzo-fusion of pentalene in the singlet and triplet states on its molecular energies and magnetically induced ring currents was examined via density functional calculations. The isomerization ...
Does aromaticity account for an enhanced thermodynamic stability? The case of monosubstituted azaborines and the stereoelectronic chameleonism of the NH2 group
(Royal Society of Chemistry (RSC), 2019)
This work was initiated by the increasing interest in BN/CC isosterism and by the long-lasting interest in the concepts of aromaticity and substituent effects. We have theoretically examined the aromaticity and stability ...
The roles of constituting oxides in rare-earth cobaltite-based perovskites on their pseudocapacitive behavior
(Elsevier, 2021)
The role and influence of strontium and its oxide on structure and capacitive response of materials containing mixed lanthanum cobalt oxides, LC, and lanthanum strontium cobalt oxides, LSC, as a capacitive materials were ...
Performance and mechanisms for Cd(II) and As(III) simultaneous adsorption by goethite-loaded montmorillonite in aqueous solution and soil
(Elsevier B.V., 2023)
A series of goethite-modified montmorillonite (GMt) materials was synthesized for the amelioration of cationic
cadmium (Cd) and anionic arsenic (As) complex contaminants in soil and water bodies. The results showed ...
Degradation of tartrazine by Oxone® in the presence of cobalt based catalyst supported on pillared montmorillonite - Efficient technology even in extreme conditions
(Elsevier, 2023)
The catalytic degradation of hazardous organic contaminants in industrial wastewater is a promising technology. Reactions of tartrazine, the synthetic yellow azo dye, with Oxone® in the presence of catalyst in strong acidic ...
Electrodeposition of copper on glassy carbon and palladium from choline chloride - ethylene glycol deep eutectic solvent
(Elsevier, 2024)
Electrodeposition of copper from deep eutectic solvents (DES) based on a mixture of choline chloride and
ethylene glycol containing CuCl2⋅2H2O at 50 ◦C and 80 ◦C was studied. Electrochemical reduction/oxidation of
Cu(II)/Cu(0) ...
