Visible light promoted photoredox C(sp3)-H bond functionalization of tetrahydroisoquinolines in flow
(Royal Society of Chemistry, 2021)
A merger of organocatalysis and visible light photoredox catalysis performed in flow allowed access to a wide range of functionalizedN-aryl-substituted tetrahydroisoquinolines (THIQs) in a formal C-H oxidation/Mannich ...
Fatigue fracture analysis of helicopter landing gear cross tube
(Elsevier, 2021)
This paper presents the failure analysis results of the helicopter skid landing gear. The helicopter skid landing gear fractured while the helicopter was on the ground at the airport. The aft cross tube of the landing gear ...
Improvement of d–d interactions in density functional tight binding for transition metal ions with a ligand field model: assessment of a DFTB3+ U model on nickel coordination compounds
(Royal Society of Chemistry (RSC), 2020)
To improve the description of interactions among the localized d, f electrons in transition metals, we have introduced a ligand-field motivated contribution into the Density Functional Tight Binding (DFTB) model. Referred ...
Influence of C–H/X (X = S, Cl, N, Pt/Pd) Interactions on the Molecular and Crystal Structures of Pt(II) and Pd(II) Complexes with Thiomorpholine-4-carbonitrile: Crystallographic, Thermal, and DFT Study
(American Chemical Society (ACS), 2020)
Pt(II) and Pd(II) complexes (1 and 2, respectively) with thiomorpholine-4-carbonitrile (TM-CN), an N-substituted thiomorpholine derivative, were synthesized from tetrachlorido precursors in water. Structural analysis has ...
A Novel Route for Electrolytic Production of Very Branchy Copper Dendrites under Extreme Conditions
(IOP Publishing Limited, 2021)
Copper electrodeposition in a form of powder was examined using the pulsating overpotential (PO) regime from the sulfate electrolyte without or with an addition of various concentrations of chloride ions. Morphological and ...
Use of carbon paste electrode and modified by gold nanoparticles for selected macrolide antibiotics determination as standard and in pharmaceutical preparations
(Elsevier, 2020)
In this work, carbon paste electrode (CPE) and carbon paste electrode modified with gold nanoparticles (AuNPs/CPE) were employed with rapid direct anodic square wave voltammetry (SWV) for macrolide antibiotics erythromycin ...
New Theoretical Insight into Fluorination and Fluorine–Fluorine Interactions as a Driving Force in Crystal Structures
(American Chemical Society (ACS), 2020)
Fluorination of compounds causes an increase in the proton-donating ability and a decrease in the proton-accepting capacity of groups in their vicinity. The formation of F···F interactions is followed by the shift of the ...

(Springer, 2020)
New anticancer platinum(II) compounds simultaneously targeting tumor cells and tumor-derived neoangiogenesis, with new DNA interacting mode and large therapeutic window are appealing alternative to improve efficacy of ...
Autochthonous and international grape varieties grown in Serbia - Phenolic and elemental composition
(Elsevier, 2021)
The phenolic and elemental profiles of Serbian autochthonous grape varieties ‘Smederevka’ and ‘Plovdina’ were studied and compared with some international varieties. Total phenolic content and radical scavenging activity ...
