New copper (II) complexes derived from azo pyridone dyes: Structure characterization, thermal properties, and molecular docking studies
(John Wiley and Sons Ltd., 2023)
Two azo dye ligands, bearing different substituents (chlorine atom or methoxy group) in the para-position of the phenyl ring, were employed for the synthesis of two Cu(II) chelates. Full structural affirmation of complexes ...
The development of a combined enzymatic and microbial fermentation as a viable technology for the spent coffee ground full utilization
(Biomass Conversion and Biorefinery, 2023)
This study demonstrated the innovative biotransformation aspect of spent coffee grounds (SCG) by application of the specific enzymatic cocktail with addition of lactic acid bacteria strain Lactobacillus rhamnosus (ATCC (R) ...
Continuous production of fructo-oligosaccharides using selectively immobilized fructosyltransferase from Aspergillus aculeatus onto Purolite® A109
(Korean Society of Industrial Engineering Chemistry, 2023)
Within this study, the investigation of potential selective immobilization of fructosyltransferase (FTase) derived from Aspergillus aculeatus (from commercial enzyme preparation Pectinex® Ultra SP-L) onto the polystyrenic ...
Fired pressed pellet as a sample preparation technique of choice for an energy dispersive X-ray fluorescence analysis of raw clays
(Elsevier B.V., 2023)
In this paper, the main subject concerns comparing different techniques to prepare raw clay samples for energy-dispersive X-ray fluorescence spectrometry (EDXRF). Three kinds of sample preparation procedures are examined, ...
Activation of Osmium by the Surface Effects of Hydrogenated TiO2 Nanotube Arrays for Enhanced Hydrogen Evolution Reaction Performance
(American Chemical Society, 2023)
Efficient cathodes for the hydrogen evolution reaction (HER) in acidic water electrolysis rely on the use of expensive platinum group metals (PGMs). However, to achieve economically viable operation, both the content of ...
Lignin based microspheres for effective dyes removal: Design, synthesis and adsorption mechanism supported with theoretical study
(Academic Press, 2023)
Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological ...
Hydrogen evolution at Ni foam electrodes and Ni-Sn coated Ni foam electrodes
(Elsevier B.V., 2023)
The hydrogen evolution reaction (HER) was investigated in 1.0 M KOH at 25 °C at Ni foams with different pore sizes (450–1200 µm), and at the Ni-Sn/Ni foam electrodes, where Ni-Sn alloys were electrodeposited from the ...
Selective laser sintered Pipe Ring Notched Tension specimens for examination of fracture properties of pipeline materials
(Elsevier Ltd., 2023)
In order to develop a non-standard method for determining the resistance to fracture and damage of pipeline materials, a new geometry of ring-shaped specimens with sharp notches or cracks has been defined. The need to ...
Two-way reaction of versatile peroxidase with artificial lignin enhances low-molecular weight fractions
(John Wiley and Sons Inc, 2023)
In recent years, versatile peroxidase (VP) has emerged as a promising enzyme for biotechnological applications, as it can oxidize lignin without the external mediators. To gain insights into the breakdown process of ...
A Novel Strategy for the Separation of Functional Oils from Chamomile Seeds
(Springer, 2023)
The main aim of this study was to evaluate the oils from chamomile seeds as a new source of bioactive compounds suitable for human consumption. A green extraction technique with supercritical carbon dioxide (sc-CO2) at ...
