NMR-based metabolomics for frauds detection and quality control of oregano samples
(Elsevier, 2021)
In this work 1H NMR metabolomics has been employed for quality control of oregano samples. NMR data and morphological analysis (MA) were combined by PCA, obtaining a model able to individuate non-marketable samples, and ...
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 ...
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 ...
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 ...
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 ...
Multi-disciplinary Shape Optimization of Missile Fin Configuration Subject to Aerodynamic Heating
(American Institute of Aeronautics and Astronautics, 2020)
The main goal of this paper is to expand previously conducted study and consequently to upgrade the proposed multimodular numerical framework developed for fluid–structure interaction simulation (FSI) and multidisciplinary ...
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 ...
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 ...
