Application of a novel poly(SMAm)-Tris-Fe3O4 nanocomposite for selective extraction and enrichment of Cu(I) /Cu(II) from beer, soft drinks and wine samples, and speciation analysis by micro-volume UV-Vis spectrophotometry
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2021)
In this study, a novel functional nanocomposite was synthesized, characterized and selectively used in pHcontrolled separation, pre-concentration and speciation analysis of Cu(I) and Cu(II) from sample matrices where ...
Self-adjoint extensions for a class of singular operators
(Turkish Journal of Mathematics, 2021)
In this study, we consider the domains of the minimal and maximal operators generated of singular
differential-expression-type Sturm–Liouville and obtain all self-adjoint extensions of the operator in terms of ...
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

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 ...
