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 ...
Investigations substituent effect on structural, spectral and optical properties of phenylboronic acids
(ELSEVIER, 2021)
Ortho- and para-substituent arylboronic acid are investigated. Geometric structure and structural proper ties of these compounds are done. IR and NMR spectrum are calculated for the spectral characterizations.
Contour ...
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 ...
Equilibrium, Thermodynamic, and Density Functional Theory Modeling Studies for the Removal of Dichromate Ions from Wastewater Using Calix[4]arene Modified Silica Resin
(ACS, 2021)
Water is contaminated by different toxicants such as anions, cations, and organic waste products. In this regard, this study reveals the removal of Cr2O7 ions from water using calix[4]arene modified silica (CMS) resin under ...
BSA/DNA binding behavior and the photophysicochemical properties of novel water soluble zinc (II) phthalocyanines directly substituted with piperazine groups
(Springer, 2021/05/04)
In the current research, two novel zinc(II) phthalocyanines (ZnPcs) (1 and 2) directly connecting with 4-(4-methylpiperazin-1-yl)phenyl groups have been synthesized through the Suzuki–Miyaura coupling reaction. These ZnPcs ...
Interaction of water soluble cationic gallium (III) phthalocyanines with different G-quadruplex DNAs
(Elsevier, 2021/11/1)
Small molecule-G-quadruplex DNA interaction has been gained considerable interest due to existence of G-quadruplex structures in telomeres and promotor regions of proto-oncogenes. In the present study, the interaction of ...
Investigation of Binding behaviour of a water-soluble gallium (III) phthalocyanine with double-stranded and G-quadruplex DNA via experimental and computational methods
(Elsevier, 2021/15/09)
DNA is an important target for the development of chemotherapeutic drug design due to increased and uncontrolled cell proliferation of cancer cells. In the present study, the affinity of water-soluble gallium(III) ...
Analysis of genetic variation in an important pest, Tuta absoluta, and its microbiota with a new bacterial endosymbiont
(Turkish Journal of Agriculture and Forestry, 10/02/2021)
Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production, resulting in up to
100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic ...
