Tailoring the properties of waterborne polyurethanes by incorporating different content of poly(dimethylsiloxane)
(Elsevier, 2021)
A series of novel waterborne polyurethanes (WBPUs) was synthesized using α,ω-dihydroxypropyl poly(dimethylsiloxane) (PDMS), isophorone diisocyanate (IPDI), 2,2-bis-(hydroxymethyl) propionic acid (DMPA) and triethylamine ...
Content and distribution of major and trace elements as a tool to assess the genotypes, harvesting time, and cultivation systems of potato
(Elsevier, 2021)
The effects of organic versus integral and conventional crop management on content and distribution of major and trace elements in different varieties of potato were investigated in a three year field trial. A set of 48 ...
Novel azo pyridone dyes based on dihydropyrimidinone skeleton: Synthesis, DFT study and anticancer activity
(Elsevier, 2021)
Seven novel azo dyes with 2-pyridone and dihydropyrimidinone moieties have been synthesized and thoroughly characterized. The azo-hydrazone tautomerism has been investigated by experimental and theoretical approaches. ...
Study on the assessment of humification processes during biodegradation of heavy residual fuel oil
(Elsevier, 2021)
The aim of this study was to investigate the creation of humic substances during biodegradation of heavy residual fuel oil, because there are indications that substances similar to humic substances are generated during ...
Principal component analysis of morphological descriptors for monitoring surface defects induced by thermal shock
(Elsevier, 2021)
Pattern recognition techniques are applied to various morphological descriptors to monitor the formation and propagation of surface defects of materials subjected to thermal shock. A low-cement high-alumina castable was ...
Effect of mesoporous silica nanoparticles on the properties of polyurethane network composites
(Elsevier, 2021)
Novel polyurethane nanocomposite (PUN) materials containing different surface-functionalized mesoporous silica nanoparticles (MSNs) were prepared by in situ polymerization methodology. Polyurethane network was formed from ...
The NaxMnO2 materials prepared by a glycine-nitrate method as advanced cathode materials for aqueous sodium-ion rechargeable batteries
(Elsevier, 2021)
Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies ...
Antioxidative responses of duckweed (Lemna minor l.) to phenol and rhizosphere-associated bacterial strain hafnia paralvei c32-106/3
(MDPI, 2021)
Duckweed (L. minor) is a cosmopolitan aquatic plant of simplified morphology and rapid vegetative reproduction. In this study, an H. paralvei bacterial strain and its influence on the antioxida-tive response of the duckweeds ...
Green pH- and magnetic-responsive hybrid hydrogels based on poly(methacrylic acid) and Eucalyptus wood nanocellulose for controlled release of ibuprofen
(Springer, 2021)
pH- and magnetic-sensitive hybrid hydrogels based on poly(methacrylic acid) (PMAA), nanocellulose (NC), carboxymethyl cellulose (CMC) and magnetite particles (MN) were prepared as ibuprofen delivery system. NC was isolated ...
Obtaining jute fabrics with enhanced sorption properties and “closing the loop” of their lifecycle
(Elsevier, 2021)
The objective of this investigation was to obtain jute fabrics with enhanced sorption properties (by using simple and cost-effective alkali and oxidative modifications) and a long life cycle. The applied alkali modifications ...
