Carbohydrate – Protein aromatic ring interactions beyond CH/π interactions: A Protein Data Bank survey and quantum chemical calculations
(Elsevier, 2020)
The geometries of the contacts between monosaccharides and aromatic rings of amino acids found in X-ray crystallography structures, in the Protein Data Bank (PDB), were analyzed, while the energies of the interactions were ...
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 ...
Assessment of density functional approximations for calculation of exchange coupling constants in thiocyanato and cyanato double bridged binuclear Ni(II) complexes / Испитивање апроксимативних функционала густине за израчунавање константи купловања у двоструко премошћеним тиоцијанато и цијанато бинуклеарним Ni(II) kомплексима
(Belgrade : Serbian Chemical Society, 2020)
In the present work, we examine the magnetic properties of 8 "end-to-end" thiocyanato, and 3 "end-to-end" cyanato double bridged Ni(II) binuclear complexes. Thiocyanato complexes are weakly ferromagnetic. Cyanato bridged ...
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 ...
Synthesis, X-ray structure and DFT calculation of magnetic properties of binuclear Ni(II) complex with tridentate hydrazone-based ligand / Синтеза, кристална структура и прорачуни функционала густине магнетних својстава бинуклеарног комплекса Ni(II) са тридентатним хидразонским лигандом
(Belgrade : Serbian Chemical Society, 2020)
Binuclear double end-on azido bridged Ni(II) complex (1) with composition [Ni2L2(μ-1,1-N3)2(N3)2]×6H2O, (L = (E)-N,N,N-trimethyl-2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethan-1-amin) was synthesized and characterized ...
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 ...
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 ...
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 ...
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 ...
