Dehydrogenative C(sp3)–H bond functionalization of tetrahydroisoquinolines mediated by organic oxidants under mild conditions
(Royal Society of Chemistry (RSC), 2019)
The organocatalyzed Mannich reaction of unsubstituted and N-aryl-substituted tetrahydroisoquinolines (THIQs) and the Strecker reaction of several N-aryl-substituted THIQs through dehydrogenative C(sp3)–H bond functionalization ...
The Spatial Patterns of Red Beds and Danxia Landforms: Implication for the formation factors–China
(Springer Nature Publishing AG, 2019)
This research examined the distribution features of red beds and 1,100 Danxia landform sites across
China, while probing the relationship between these spatial patterns and geological elements. This
study is based on ...
The socio-economic impact timeline in Serbia for persistent organic pollutants (POPs)
(ELSEVIER, 2019)
Assessing the socio-economic impact of dangerous chemicals, including persistent organic pollutants (POPs) as a
specific segment, includes analysis of their impacts on human health, on the environment and on local ...
Erosive wear properties of ZA-27 alloy-based nanocomposites: Influence of type, amount, and size of nanoparticle reinforcements
(Springer, 2019)
Metal matrix nanocomposites (MMnCs) comprise a metal matrix filled with nanosized reinforcements with physical and mechanical properties that are very different from those of the matrix. In ZA-27 alloy-based nanocomposites, ...
Fungal transformation and reduction of phytotoxicity of grape pomace waste
(Elsevier, 2019)
Grape pomace (GP) from Vitis labrusca, the main byproduct from “American table wine” production, is recalcitrant to degradation, and its accumulation is a serious problem with negative environmental impacts. In this work, ...
The influence of low-frequency magnetic field regions on the Saccharomyces cerevisiae respiration and growth
(Elsevier, 2019)
The influence of four low-frequency magnetic field (MF) ranges 10–300 Hz, 10–100 Hz, 10–50 Hz and 50–100 Hz in scanning regime (all frequencies from selected range were scanned during 100 s repetitively during 24 h) on ...
Briggs-Rauscher reaction as a novel electrochemical detector for phosphate tungsten and phosphate molybdenum bronzes
(Elsevier, 2019)
Briggs-Rauscher (BR) oscillatory reaction is a chemical system very sensitive to different analyte addition. Changes in oscillatory dynamics, by analyte addition, could be successfully used for the determination of analyte ...
Fatigue endurance design of plates with two semicircular edge notches and one quarter-elliptical corner crack or through-the-thickness crack
(Elsevier, 2019)
This paper presents an investigation on the failure of plates with double-edge notches and fatigue damage. The
main aim is to develop a computational model for estimating the behaviour of a quarter-elliptical corner crack ...
Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier, 2019)
Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution ...
