What is the preferred geometry of sulfur–disulfide interactions?
(Royal Society of Chemistry, 2020)
Non-covalent interactions between disulfide fragments and sulfur atoms were studied in crystal structures of small molecules and by quantum chemical calculations. Statistical analysis of the geometrical data from the ...
Increased yield of enzymatic synthesis by chromatographic selection of different N-glycoforms of yeast invertase
(Wiley, 2020)
Invertases are glycosidases applied for synthesis of alkyl glycosides that are important and effective surfactants. Stability of invertases in the environment with increased content of organic solvent is crucial for increase ...
Bisaurones-enzymatic production and biological evaluation
(Royal Society of Chemistry, 2020)
The Trametes versicolor laccase catalyzed oxidation of chalcone butein afforded four dimers of aurone sulfuretin (i.e. two regioisomeric pairs of diasteromers, 1-4) as the major products. The formation of the dimers was ...
Self-Assembly and Biorecognition of a Spirohydantoin Derived from α-Tetralone: Interplay between Chirality and Intermolecular Interactions
(John Wiley and Sons Inc., 2020)
A racemic spirohydantoin derivative with two aromatic substituents, a tetralin and a 4-methoxybenzyl unit, was synthesized and its crystal structure was determined. To define the relationship between molecular stereochemistry ...
Natural Pigment from Madder Plant as an Eco-Friendly Cathode Material for Aqueous Li and Na-Ion Batteries
(IOP Publishing, 2021)
Modifying commercial Li-ion batteries to become more environmentally friendly is of a growing concern. This paper provides anexamination of a potential replacement for commercial cathode material using a naturally occurring ...
Structural, morphological and textural properties of iron manganite (FeMnO3) thick films applied for humidity sensing
(Elsevier, 2020)
Iron manganite (FeMnO3) powder with a cubic (bixbyite,−Ia3) crystal structure was obtained by a solid statereaction. Thick film paste (powder+organic vehicles) was screen printed on alumina substrate with test interdigitatedPdAg ...
Insight into the Origin of Pyrocatechol Inhibition on Oscillating Bray-Liebhafsky Reaction: Combined Experimental and Theoretical Study
(Chemical Society of Japan, 2020)
The pyrocatechol inhibitory effect on the oscillatory Bray-Liebhafsky (BL) reaction is reported. Obtained results are compared with those available in the literature (R. Cervellati et al, Helvetica Chimica Acta 2001) for ...
Controlling Pd-Catalyzed N-Arylation and Dimroth Rearrangement in the Synthesis of N,1-Diaryl-1H-tetrazol-5-amines
(American Chemical Society (ACS), 2021)
The Pd-catalyzed N-arylation method for the synthesis of eighteen N,1-diaryl-1H-tetrazol-5-amine derivatives is reported. By running the reactions at 35 °C, compounds were isolated as single isomers since the undesired ...
Ideal efficiency of resonant cavity-enhanced perovskite solar cells
(Springer Science and Business Media LLC, 2020)
Perovskite solar cells (PSCs) have attracted significant attention in recent years due to the rapid increase in device efficiency (reaching over 25% in 2019), ease of fabrication, and the potential to produce low-cost ...
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 ...
