A new pre-concentration procedure based on poly(styrene-co-maleamide and imide) copolymers modified with 2-hydrazinobenzothiazole prior to spectrophotometric monitoring of inorganic as (as As(III)) in edible vegetable oils
(Elsevier, 27 Decembe)
This study describes the development of 2-hydrazinobenzothiazole modified-amide/imide co-polymers for the extraction/pre-concentration of trace As(III), from edible vegetable oils. Their characterization was realized by ...
Novel amide- and imide-co-polymers modified with sulfathiazole as efficient chelator for selective extraction, pre-concentration and determination of trace inorganic antimony (as Sb(III)) from edible vegetable oils by ultrasound assisted-cloud point extraction coupled to micro-volume UV-spectrophotometry
(Elsevier, 22 Septemb)
The study described the synthesis, characterization, and application of newly prepared sulfathiazole-modified amide/imide co-polymers for the extraction of trace Sb(III) from edible vegetable oils. The method was based on ...

Determination of trace cobalt (II) in spices samples by ultrasonic assisted cloud point extraction with spectrophotometry
(JOURNAL OF MOLECULAR STRUCTURE, 2023)
In this study, ultrasonic assisted cloud point extraction (UA-CPE) method was developed for the determination of Cobalt (II) (Co(II)) in spices. After extraction and preconcentration, the Co(II) contents of the samples ...
Immobilization of pectinase on chitosan-alginate-clay composite beads: Experimental, DFT and molecular docking studies
(Elsevier, 2023)
Pectinase was immobilized on chitosan-alginate-clay (CAC) beads using epichlorohydrin (ECH) as the crosslinker. Prepared beads and immobilization product were analyzed by Fourier Transform Infrared Spectrophotometry (FTIR) ...
Investigation of substituent effect on rhenium complexes by DFT methods: Structural analysis, IR spectrum, quantum chemical parameter, NLO and OLED properties, molecular docking
(Elsevier, 2023)
For the synthesized 9b, 9c and 9d complexes, hypothetical complexes were formed by adding electron-withdrawing (NO2) and electron-donating (NH2) groups. Benchmark analysis was performed using the bond lengths of the ...
Modeling, spectroscopic structural properties of platinum-II complexes of 2-((phenylimino)methyl)phenolate-based ligands and research of nonlinear optical, organic light emitting diode and solar cell performances
(Elsevier, 2023)
The hypothetical Pt(B1)2, Pt(B2)2 and Pt(B3)2 complexes were modeled. B1, B2 and B3 are Schiff bases, 2-((phenylimino)methyl)phenolate, 4-methyl-2-((phenylimino)methyl)phenolate and 4-nitro-2-((phenylimino)methyl)phenolate, ...
The complete mitochondrial genome sequence of Pachycephus smyrnensis Stein, 1876 (Hymenoptera: Cephidae) with phylogenetic analysis
(Taylor \& Francis, 2023)
The complete mitochondrial genome of Pachycephus smyrnensis Stein, 1876 collected from Sivas, Turkey, is described. The circled genome is 20,393 bp in length and contains a typical set of 37 genes. The missing control ...
RECONSTRUCTION OF A STURM-LIOUVILLE OPERATOR WITH SOME NONLOCAL BOUNDARY CONDITIONS
(2023)
In the present paper, a Sturm-Liouville equation and two nonlocal
boundary conditions which are generalized versions of Bitsadze-Samarskii-type
conditions are considered. The main goal of this paper is to obtain the ...
EIGENVALUES OF THE DIRAC OPERATOR WITH NONLOCAL BOUNDARY CONDITIONS ON TIME SCALES
(2023)
In this paper, a Dirac system under some integral type nonlocal boundary conditions on a discrete set is considered. A formulation for the number of eigenvalues of the problem is obtained and a method for calculation of ...
