Use of new polymeric composites for preconcentration of trace Ag+ ions from the selected mushroom/vegetables by ultrasoundassisted cloud-point extraction coupled to microvolume UV-Vis spectrophotometry
(Taylor&Francis, 2021)
The magnetic nano-composites based on the tris(hydroxymethlmethyl)
aminomethane-modified maleic anhydride-co-styrene copolymers
and Fe3O4 nano-particles were prepared as new potential
chelating agents for ultrasound-a ...
A New Enrichment Method for Quantification of 5-Hydroxymethylfurfural by Indirect Flame Atomic Absorption Spectrometry in Honey and Jam Samples
(OXFORD UNIV PRESS INCJOURNALS DEPT, 2001 EVANS RD, CARY, NC 27513, 2021)
Background: Because of increasing amounts of 5-hydroxymethylfurfural (5-HMF) in processed foods and the complexity of the matrix, monitoring of trace 5-HMF requires accurate and reliable methods. Hence, an efficient sample ...
Half-inverse problems for the quadratic pencil of the Sturm–Liouville equations with impulse
(2021)
In this paper, we consider the inverse spectral problem for
the impulsive Sturm–Liouville differential pencils on [0, π]
with the Robin boundary conditions and the jump conditions
at the point 𝜋������

Selective extraction and enrichment of 5-hydroymethylfurfural from honey, molasses, jam and vinegar samples prior to sensitive determination by micro-volume UV-vis spectrophotometry
(CADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new method was developed for the extraction/enrichment of 5-hydroxymethylfurfural (5-HMF) from sample matrix prior to analysis. The method is based on the selective formation of the imine adduct and ionpair ...
Eco-friendly trace analysis of silver in beer/wine samples using a new co-polymeric nanocomposite based-ultrasound assisted-cloud point extraction combined with spectrophotometry
(ACADEMIC PRESS INC ELSEVIER SCIENCE525 B ST, STE 1900, SAN DIEGO, CA 92101-4495, 2021)
In this study, a new magnetic nanocomposite based on the tris(2-hydroxymethyl)aminomethane-modified poly (styrene-co-N-maleimide) copolymer and Fe3O4 nanoparticles were prepared as a new micellar interface for preconcentration ...
Phylogenomic Analyses of the Tenthredinoidea Support Familial Rank of Athaliidae (Insecta, Tenthredinoidea)
(21.09.2022)
The systematic status of the genus Athalia and related genera is a perennial controversy
in sawfly taxonomy. Several authors have hypothesized that the placement of Athalia within the
Tenthredinidae is artificial, but ...
Antioxidant activities of Alyssum virgatum plant and its main components
(Springer, 01.02.2022)
The antioxidant properties of methanol extract of above-ground parts of Alyssum virgatum, an endemic plant, were analyzed.
Together with their total phenolic, flavonoid, and antioxidant capacities, their effects on reactive ...
Optoelectronic and electric properties of 8‐Hydroxyquinoline-Based complexes with divalent metal ions
(Elseiver, 01.04.2022)
Firstly, the metallic complexes containing 8‐hydroxyquinoline were designed theoretically to investigate their optoelectronic properties (M = Sc2+, Ti2+, V2+, Cr2+, Mn2+, Fe2+, Co2+, Ni2+, Cu2+, Zn2+ Pd2+, and Pt2+ and Q: ...
