Synthesis and pharmacological evaluation of novel cis and trans 3‑substituted anilidopiperidines
(Springer Nature, 2020)
Background 4-Anilidopiperidine class of synthetic opioid analgesics, with it’s representative fentanyl, are by far the most potent and clinically significant for the treatment of the severe chronic and surgical pain. ...
Polysaccharide-fullerene supramolecular hybrids: Synthesis, characterization and antioxidant activity
(Elsevier, 2020)
An efficient encapsulation of the fullerene into two hydrophobized and one native polysaccharide provided water soluble supramolecular hybrids. After covalent modification of polysaccharides by cholesterol, noncovalent ...
Fabrication and characterization of luminescent Pr3+ doped fluorapatite nanocrystals as bioimaging contrast agents
(Elsevier, 2020)
Fluorapatite doped with rare-earth elements has a wide-range of biomedical applications. Here, a new type of fluorapatite nanocrystals doped with praseodymium (FAP-Pr) with excitation-emission profiles in visible part of ...
What is the nature of bonding in [Fe(CO)3(NO)]− and [Fe(CO)4]2−?
(Springer Nature, 2020)
To shed new light on the electronic structure of [Fe(CO)3(NO)]¯ complex ion, DFT-based analysis of the nature of chemical bonding has been performed. For this purpose, the extended transition state energy decomposition ...
Ionic diffusion in iPP: DC electrical conductivity
(Elsevier, 2020)
This study provides a new insight into the relationships between absorption and adsorption processes that occur during the treatment of iPP in aqueous solutions of metal-chloride salts, as well as the impact of these ...
Comparative study of lignocellulosic biomass and its components as electrode modifiers for detection of lead and copper ions
(Elsevier, 2020)
Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A ...
Low-friction, wear-resistant, and electrically homogeneous multilayer graphene grown by chemical vapor deposition on molybdenum
(Elsevier, 2020)
Chemical vapour deposition (CVD) is a promising method for producing large-scale graphene (Gr). Nevertheless, microscopic inhomogeneity of Gr grown on traditional metal substrates such as copper or nickel results in a ...
Characterisation of the binding of dihydro-alpha-lipoic acid to fibrinogen and the effects on fibrinogen oxidation and fibrin formation
(Elsevier, 2020)
A reduced form of the alpha-lipoic acid, dihydro-alpha-lipoic acid (DHLA) is a potent, naturally occurring antioxidant which can be consumed as food constituent or as supplement at doses up to 600 mg/day. DHLA has inhibitory ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT–IR, 1H and 13C NMR, UV–Vis, and PL spectroscopy. Photophysical properties of the dyes were examined ...
Effects of different polymers and solvents on crystallization of the NaYF4:Yb/Er phase
(Springer, 2020)
Up-converting NaYF4:Yb,Er nanoparticles were obtained by polymer-assisted solvothermal synthesis using a common solution of hydrated RE nitrates in ethanol or ethylene glycol. It was shown that polymer choice (polyacrylic ...
