Etching of Uncompensated Convex Corners with Sides along <n10> and <100> in 25 wt% TMAH at 80 °C
(MDPI, 2020)
This paper presents etching of convex corners with sides along <n10> and <100> crystallographic directions in a 25 wt% tetramethylammonium hydroxide (TMAH) water solution at 80 °C. We analyzed parallelograms as the mask ...
Charge assisted assembly of zwitterionic pyridone hydrates
(Elsevier, 2021)
Two pyridone derivatives, bearing the pyridinium moiety (1), or dimethylpyridinium moiety (2), have been synthesized and their crystal structures have been determined. The compounds crystalize in hydrated zwitterionic forms ...

(Taylor & Francis, 2020)
In this article, synthesis, spectral and X-ray structure characterization, antimicrobial activity and Brine shrimp test of two new Cu(II) complexes with a salicylaldehyde derivative have been reported. Complexes ...
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 ...

(MDPI, 2021)
Enzymatic hydrolysis of food proteins is convenient method to improve their functional properties and physiological activity. Herein, the successful covalent attachment of alcalase on alginate micron and submicron beads ...
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 ...

Antioxidant Capacity and Quality of Human Milk and Infant Formula Determined by Direct Current Polarography
(Springer, 2021)
Antioxidants present in infant food contribute to its nutritive value and provide protection from oxidative damage. Here, a direct current polarographic method, based on a decrease of anodic current from the hydroxoperhy ...
Synthesis, physicochemical characterization, and TD–DFT calculations of monothiocarbohydrazone derivatives
(Springer, 2021)
Derivatives of thiocarbohydrazone studied so far have shown great biological activity such as antioxidant, antimicrobial, and
anticancer.Most of these compounds are bis-substituted derivatives,while monothiocarbohydrazones ...
