Vidrih R., Vidakovič S., Abramovič H. (2010): Biochemical parameters and oxidative resistance to thermal treatment of refined and unrefined vegetable edible oils. Czech J. Food Sci., 28: 376–384. In human nutrition fats are physiologically important food constituents but also the components most liable to oxidative degradation. The oils included in the study were refined (sunflower, extra-sunfl...

Abstract PLA and its nanocomposite containing 3% chitosan nanoparticles (PLA-3CsNP) were studied to see how γ -irradiation affected their characteristics. Different doses of applied the investigated materials under inquiry (5–40 kGy) using 60 Co at ambient conditions. The irradiation characterized by FT-IR, GPC, mechanical tensile test, DSC, XRD, TGA in solid chloroform solutions. molecular wei...

the nanostructured anatase tio2 with high thermal stability was prepared by polymeric sol-gel method without any additives. the particle size distribution of polymeric titania sol was determined by dynamic light scattering (dls). then properties of obtained titania were investigated by tg-dta, xrd, fesem and tem. also, the decolorization capability of resultant anatase was evaluated using methy...

The objectives of this investigation are the studies on the effect of copper ion on photolytic degradation of ethylenediaminetertraaceticacid (EDTA), the effect of EDTA on electrolytic recovery of copper as well as the introduction of a novel combined photolytic and electrolytic cell system for simultaneous recovery of copper and the degradation of EDTA.In this experimental study, ...

Anatase N-doped TiO2 nanoparticles were synthesized using ultrasound at low frequency and room temperature. The samples characterized by techniques including XRD, TEM, HRTEM, FT-IR, XPS, and UV–Vis spectroscopy. XPS indicated the existence of nitrogen as an anion dopant within the TiO2 lattice. The solar photocatalytic activity of N-doped TiO2 studied for th...

Cellulose tri-stearate (CTs) was synthesized employing trifluoroacetic anhydride (TFAA), stearic acid (SA), with microcrystal cellulose (MCC) and characterized with FT-IR and 1 H-NMR. The degree of substitution of CTs was determined by the traditional saponification method and 1 H-NMR. The thermal properties of CTs were investigated by the thermogravimetric analysis (TGA) under Ar flow in dynam...

Thermal degradation of modern and ancient linen fabrics was investigated by DSC and FTIR analysis in order to find a possible correlation between thermal behaviour and the age of linen. A similar pattern to that for cotton degradation was found, and the essential influence of impurities occurring naturally or occasionally was found. Moreover, in the case of old linen fabrics, a cleaning treatme...

Catastrophic failure of lithium-ion batteries occurs across multiple length scales and over very short time periods. A combination of high-speed operando tomography, thermal imaging and electrochemical measurements is used to probe the degradation mechanisms leading up to overcharge-induced thermal runaway of a LiCoO2 pouch cell, through its interrelated dynamic structural, thermal and electric...
