A new series of metal complexes of Ti(IV), V(IV), Y(III), Zr(IV), Ce(IV) and U(VI) with levofloxacin (Levo) were synthesized and characterized by elemental analysis, molar conductivity, magnetic moment measurements, UV–Vis, FT-IR and 1H NMR, XRD as well as TG-DTG techniques. The data indicated that levofloxacin reacts as a bidentate ligand chelate ...

The diffusion of oxygen (O2) plays an important role in the heterogeneous oxidation of coal and biomass, but is inadequately understood. This work aims to study the influence of intra-, inter-particle and external O2 diffusions on the high-temperature heterogeneous oxidation using the TG-FTIR technique and two bituminous coals as example. Results s...

The enthalpies of combustion and formation in solid state of tryptophan stereoisomers (l- and d-) and of their racemic mixture are reported (−406.6 ± 3.1, −407.4 ± 2.1, −410.7 ± 2.3 kJ mol−1, respectively) and compared to the literature and calculated data. The transformation (melting—decomposition) points and the associated thermal effects were de...

Feline hepatic lipidosis (FHL) is a common and potentially fatal liver disorder. Although the pathophysiologic mechanisms of FHL remain elusive, there is an imbalance between the influx of fatty acids from peripheral fat stores into the liver, de novo liposynthesis, and the rate of hepatic oxidation and dispersal of hepatic TAG via excretion of ver...

The thermal behavior of lavender and sage essential oils (EOs) and also that of their main components (camphor and 1,8-cineole) were studied by thermogravimetry (TG) at different scan rates under inert gas atmosphere up to about 140 °C. All the samples investigated undergo a single-step evaporation starting from ambient temperature without evidence...

Among the widespread pests belongs Hylotrupes bajulus, which attacks mostly wooden beams in the roof of the houses. Heat sterilisation of wood is used to kill all forms of pests (eggs, larvae, adults) in solid wood materials. We compared thermal stability of heat sterilised silver fir wood to larval frass in regard to fire safety. The samples were ...

This study aims at evaluating the main hydration reactions of a type II Portland cement, when partially substituted by the fines of spent cracking catalyst (Epcat), during the first 28 days of hydration. Pastes prepared with a 0.5 water/(cementitious material) ratio up to 30 mass% substitution of cement by Epcat were analyzed after 4 and 24 h and a...

The microbially induced calcite precipitation was used to bind sand grains, yielding consolidated material known as bio-mortar. An aerobic, urease-active and nonpathogenic Sporosarcina pasteurii microorganism was used for the induction of calcite precipitation. Three different temperatures (250, 500 and 750 °C) were applied to examine the firing re...

Wildfires are an integral feature of the Australian continent. To estimate the rate of spread of wildfires using computational models it is important to know the kinetic parameters of the materials that constitute the fuel load in forests. These kinetic parameters are utilised in pyrolysis and combustion sub-models of a computational model. In the ...
