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, ...
Heterofunctional epoxy support development for immobilization of fructosyltransferase from Pectinex® Ultra SP-L: batch and continuous production of fructo-oligosaccharides
(Royal Society of Chemistry, 2022)
In this study, a heterofunctional carrier was obtained by modification of a macroporous polystyrene ion exchange resin with primary amino groups (Purolite® A109) with epichlorohydrin, in view of achieving covalent ...
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 ...
The role of viscoelasticity in long time cell rearrangement
(Elsevier Ltd., 2022)
Cell rearrangement caused by collective cell migration (CCM) during free expansion of epithelial monolayers has become a landmark in our current understanding of fundamental biological processes such as tissue development, ...
The effect of SrO and La2O3 addition on the crystallization characteristics and sintering behavior of distinct polyphosphate glasses
(Springer Science and Business Media B.V., 2022)
The goal of this research is to investigate the effect of SrO and La2O3 addition on the crystallization characteristics and sintering behavior of polyphosphate glasses. Differential scanning calorimetry (DSC), hot stage ...
Sr,Mg co-doping of calcium hydroxyapatite: Hydrothermal synthesis, processing, characterization and possible application as dentin substitutes
(Ceramics International, 2022)
The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) ...
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 ...
