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 ...
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 ...
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 ...
The application of zeolite nanopowder for the construction of the dense composite polymer membranes for carbon dioxide separation
(Inst Materials Physics, Bucharest, 2012)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Recent Developments in Bioprocessing of Recombinant Antibody Fragments
(Springer, 2023)
Biotechnological and biomedical applications of antibodies have been on a steady rise since the 1980s. As unique and highly specific bioreagents, monoclonal antibodies (mAbs) have been widely exploited and approved as ...
Effect of diffusion on steady state stability of an oscillatory reaction model
(Elsevier, 2023)
The effect of diffusion on the steady-state stability of an oscillatory chemical reaction model was investigated using stoichiometric network analysis and numerical simulations. Under both spatially uniform and nonuniform ...
Stochastic Phase Transition Dynamics in Nonequilibrium System: Holographic Study
(American Chemical Society (ACS), 2023)
This paper presents a holographic study of the phase transition that occurs in a nonequilibrium system. The chosen model is a unique Briggs–Rauscher oscillatory reaction that, first, follows a deterministic pattern (namely, ...
Unusual mode of reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
The reactivity of 2-alkylidene-4-oxothiazolidine S-oxides under the Pummerer reaction conditions, using Ac2O, TFAA, SOCl2 and SOBr2 as initiators, has been examined. Almost all reactions proceeded with absolute regioselectivity ...
Catalytic oxidations of enolizable ketones using 2-alkylidene-4- oxothiazolidine vinyl bromide
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Direct oxidation of enolizable ketones to α-hydroxy derivatives, vicinal dicarbonyls or tricarbonyl compounds has been achieved by a catalytic amount of 2-alkylidene-4-oxothiazolidine vinyl bromide in DMSO as a solvent. ...
Electron Delocalization in Electron-Deficient Alkenes and Push-Pull Alkenes
(Wiley-V C H Verlag Gmbh, Weinheim, 2017)
We have studied pi electron delocalization in electron- deficient alkenes and push- pull alkenes by means of natural bond orbital analysis at the B3LYP/6-311+ G(d,p) level. The study revealed that the rarely mentioned pi ...
