As a part of our efforts to characterize the electron attachment reactions of the group IV tetrahalides, XY4 (X = C, Si, Ge and Y = F, Cl, Br) we here follow up on our previous study on XF4 and report electron attachment to the tetrabromides: CBr4, SiBr4 and GeBr4 in the incident electron energy...

Six gallium(III) complexes (Ga1–Ga6) with 2‑quinolinecarboxaldehyde thiosemicarbazone analogues were synthesized and characterized. These gallium(III) complexes exhibited potent anticancer activity and exceeded that of the corresponding metal free ligands. Importantly, these gallium(III) comple...

In the present work, an α-aminophosphonate extractant di(2-ethylhexyl) [N-(2-ethylhexyl)aminomethyl] phosphonate (Cextrant 230, L) was applied for the selective extraction and recovery of Ga(III) from the chloride solutions. The extraction of Ga(III) was compared with that of other metal ions s...

An efficient solvent extraction process was developed for extraction of gallium (III) from acidic chloride medium using the ionic liquid Cyphos IL 104 diluted with toluene. The kinetics of gallium extraction was very fast. The extraction percent of gallium was found to increase with increase in ...

The synthesis, liquid crystalline and optical properties of copper (II), oxovanadium (IV) and gadolinium (III) complexes derived from polar Schiff’s bases viz., N-(4-n-hexadecyloxysalicylidene)-4′-substituted anilines with methoxy, fluoro and chloro substituents in the 4-position of N-aryl moi...

This work has been aimed at identifying suitable conditions for the separation of europium/gadolinium mixture, with a high Gd content and without previous europium reduction, into a phase of high-purity Gd and a Eu-enriched mixture. Acid and basic extractants have been evaluated in a number of e...

Gadolinium zirconate (GZ) is considered as a promising top coat candidate for high temperature TBC applications. Suspension plasma spray has shown the capability to generate a wide range of microstructures including the desirable columnar microstructure. In this study, two different TBC architec...

Seven novel Gd(OAc)[S2P(OR)2]2·2CH3CN and Gd(OAc)[S2P(OR′)2]2·2CH3CN gadolinium complexes where R = Et, n-Pr, n-Bu and Ph and R′ = CH2CMe2CH2, CH2CEt2CH2, and CMe2CMe2 were synthesized and characterized by elemental analyses, Molecular weight determinations, IR and UV Visible spectroscopy. M...

In this study, tris(4-carboxy-3-benzyl-3-azabutyl) amine—a novel polyaminocarboxylate ligand—was synthesized. Two new nonionic complexes (a mononuclear complex and a dinuclear complex) of gadolinium with this ligand were also synthesized as potential magnetic resonance imaging (MRI) contrast a...

The development of a reliable and simple method for detecting single nucleotide polymorphisms (SNPs), common genetic variations in the human genome, is currently an important research area because SNPs are important for identifying disease-causing genes and for pharmacogenetic studies. Here, we ...

Having successfully obtained new CCK1 ligands holding appropriate groups on the anthranilic acid dimer used as molecular scaffold we were interested in increasing their micromolar affinity for the CCK1 receptors by modifying the spatial relationship of the main pharmacophoric groups. Since, we h...

2H-Pyran-2-ones with the defined (E)-structure of a α,β-didehydroamino acid unit were used as synthons for a series of configurationally stable (E)-α,β-didehydroamino acid derivatives containing a benzoyl protected amino function and a pyrazolyl residue. They were derived from 2H-pyran-2-one...

Recently we described an innovative class of non-peptide CCK1 antagonists keeping appropriate pharmacophoric groups on the anthranilic acid employed as a molecular scaffold. The lead compound obtained, VL-0395, characterized by the presence of Phe and the 2-indole moiety at the C- and N-termini ...

A novel and reliable method to quantify residual levels of N-(3-aminopropyl)-N-dodecylpropane-1,3-diamine in dairy products using ion-pairing reversed-phase liquid chromatography–tandem mass spectrometry (LC–MS/MS) was developed and fully validated. Sample extraction was done with salting-out ...

The uniform dispersion of Fe3O4 nanoparticles and strong interfacial bonding with epoxy matrix are crucial for Fe3O4/epoxy composite with enhanced mechanical and thermal properties. Cube pure Fe3O4 nanoparticles (PF NPs) by poly (dopamine) (PDA) coated and (3-aminopropyl) triethoxysilane (APTES)...

Two solvent-free methods were combined to modify the surface of multi-walled carbon nanotubes (MWCNTs) with a high concentration of amine functional groups. First, an oxygen-rich plasma polymer (PP) coating was deposited on the MWCNTs. Second, either tetraethylenepentamine (TEPA) or (3-aminoprop...

A series of novel 2-aminobenzamide derivatives decorated with thioquinazolinone were designed and synthesized as histone deacetylase (HDAC) inhibitors. These derivatives were evaluated for their antiproliferative activities against several human cancer cell lines including A375, Hela, A549, HCT1...

A mild and efficient trifluoromethylselenolation of acid chlorides with [(bpy)Cu(SeCF3)]2 (1) in the presence of a catalytic amount of metallic iron powder is described. Easily available benzoyl chloride derivatives and alkyl acid chlorides are smoothly converted into the corresponding Se-triflu...
