Chemical Structure and Thermal Properties versus Accelerated Aging of Bio-Based Poly(ether-urethanes) with Modified Hard Segments
PublikacjaAging of polymers is a natural process that occurs during their usage and storage. Predicting the lifetime of polymers is a crucial aspect that should be considered at the design stage. In this paper, a series of bio-based thermoplastic poly(ether-urethane) elastomers (bio-TPUs) with modified hard segments were synthesized and investigated to understand the structural and property changes triggered by accelerated aging. The bio-TPUs...

The XRD diffraction patterns of (La0.3Sr0.6Ce0.1)0.9FexTi(1-x)O3-δ (x=0.1, 0.2 and 0.3) materials after reduction at 900 deg.C in hydrogen
Dane BadawczeThe (La0.3Sr0.6Ce0.1)0.9FexTi(1-x)O3-δ (x=0.1, 0.2 and 0.3) materials were synthesized via the Pechini method. First, the reagents in the form of nitrates were weighed and dissolved in DI water. In another beaker, a stoichiometric amount of titanium (IV) butoxide (Ti(OBu)4) was mixed together with reagent-grade ethylene glycol (EG), and citric acid...

Elucidation of chemical compounds in different extracts of two Lavandula taxa and their biological potentials: Walking with versatile agents on the road from nature to functional applications
PublikacjaDue to their health-promoting and nutraceutical properties, lavenders are frequently employed in the food and pharmaceutical industries. Here, we focused on investigate the chemical profile of hexane, MeOH, and water extracts of leaf, flower, and root of L. pedunculata and L. stoechas and to assess their antioxidant, enzyme inhibitory, and antibacterial properties. The highest total polyphenolic and flavonoids contents were recorded...

Bio-Based Polyurethane Composites and Hybrid Composites Containing a New Type of Bio-Polyol and Addition of Natural and Synthetic Fibers
PublikacjaThis article describes how new bio-based polyol during the liquefaction process can be obtained. Selected polyol was tested in the production of polyurethane resins. Moreover, this research describes the process of manufacturing polyurethane materials and the impact of two different types of fibers—synthetic and natural (glass and sisal fibers)—on the properties of composites. The best properties were achieved at a reaction temperature...

Silicon oxycarbide-tin nanocomposite derived from a UV crosslinked single source preceramic precursor as high-performance anode materials for Li-ion batteries
PublikacjaIn this work, we report an innovative and facile UV light-assisted synthesis of a nanocomposite based on silicon oxycarbide (SiOC) and tin nanoparticles. SiOC ceramic matrix, containing a conductive free carbon phase, participates in lithium-ion storage, and buffers the volume changes of Li-alloying/de-alloying material. The reported synthesis procedure through a polymer-derived ceramic route involves the preparation of a single-source...

The Righi-Leduc effect: on evidence of two-band electronic structure in Nd1.86Ce0.14CuO4-y.
PublikacjaPrzedstawiono badania temperaturowe zależności oporu elektrycznego, efektu Halla (RH), przewodnictwa cieplnego (k) i współczynnika Righi-Leduc(SRL). Badania wykazały, że współczynnik RL> 0 w szerokim zakresie temperatur RH zmienia znak dwukrotnie w T=50 i 250K. Niezgodność znaków SRL i RH jednoznacznie wskazuje obecność w materiale nośników obu znaków tzn. n- i p- typu. W pracy pokazano, że transport ciepła zdominowany jest przez...
