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 ...
Biofilms in caves: easy method for the assessment of dominant phototrophic groups/taxa in situ
(Springer Science and Business Media LLC, 2020)
Domination of certain aerophytic phototrophic group or specific taxon in biofilms is connected with biofilm features recognised in situ. Well-developed, gelatinous, olive to dark-green biofilms are composed mostly of coccoid ...
Increased yield of enzymatic synthesis by chromatographic selection of different N-glycoforms of yeast invertase
(Wiley, 2021)
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 ...
Silicon Y-bifurcated microchannels etched in 25 wt% TMAH water solution
(IOP Publishing, 2020)
In this study, Y-bifurcated microchannels fabricated from a {100} silicon in 25 wt% tetramethylammonium hydroxide water solution at the temperature of 80 °C have been presented and analysed. We studied the etching of acute ...
Varietal differences of Prokupac, Evita and Čokot Zemun based on their anthocyanins content in grape skin extract
(Chemistry & Biodiversity, 2021)
In this study we have analyzed the anthocyanin composition of skin extracts of three red grape varieties Prokupac, Evita and Čokot Zemun in order to distinguish these cultivars based on their anthocyanin profile. Also, ...
Intermittent Chaos in the CSTR Bray–Liebhafsky Oscillator-Specific Flow Rate Dependence
(Frontiers Media S.A., 2020)
Dynamic states with intermittent oscillations consist of a chaotic mixture of large
amplitude relaxation oscillations grouped in bursts, and between them, small-amplitude
sinusoidal oscillations, or even the quiescent ...

Biotransformation of Perrottetin F by Aspergillus niger: New Bioactive Secondary Metabolites
(Türkiye : ACG Publications, 2021)
Biotransformation of bis-bibenzyl perrottetin F (1), isolated from the liverwort Lunularia cruciata by Aspergillus niger, has been investigated. New metabolites (2-4) have been isolated using reversed phase semipreparative ...
Corrosion behaviour of AA2024 aluminium alloy in different tempers in NaCl solution and with the CeCl3 corrosion inhibitor
(Wiley - VCH Verlag GmbH & Co, 2020)
The paper analyses the corrosion behaviour of naturally and artificially aged
AA2024 alloy in NaCl solution and in the presence of an environment ‐ friendly
corrosion inhibitor, CeCl 3 . On the basis of the values of ...
Soil erodibility in European mountain beech forests
(Canadian Science Publishing, 2021)
Forests in Europe are currently not endangered by soil erosion. However, this can change with climate change orwith intensified forest management practices. Using a newly established network of plots in beech forests across ...
