The article addresses the modelling of the maturity of concrete. The apparent activation energy is the backbone of the Arrhenius model, which is typically used to model the maturity of concrete. The maturity (or the equivalent age) is influenced by the curing temperature and it is applied when modelling the hydration process and the hardening of co...

The temperature sensitivity of soil processes is of major interest, especially in light of climate change. Originally formulated to explain the temperature dependence of chemical reactions, the Arrhenius equation, and related Q10 temperature coefficient, has a long history of application to soil biological processes. However, empirical data indicat...

An eco-friendly and economical, green synthesis method has been employed for the synthesis of iron-oxide (Fe2O3) nanoparticles by using orange peel extract as a stabilizing agent. The thermody-namic properties were evaluated using thermogravimetric analysis-diffraction scanning calorimetry (TGA-DSC), the formation of Fe2O3 nanoparticles was confirm...

The [3+2] cycloaddition (32CA) reaction of benzonitrile oxide to α-methylene cyclopentanone and propionitrile oxide to γ-methyl-α-methylene-γ-butyrolactone, yielding regio- and stereochemically defined spiroisoxazolines, has been studied at the MPWB1K/6-311G(d,p) computational level. These processes proceed by a one-step mechanism through asynchron...

This work reports the thermal degradation behaviour, kinetics and thermodynamics of two different eco-friendly plastics, viz. non-woven plastic and corn starch-based biodegradable plastics, which are commonly used nowadays as an alternative to synthetic plastics. In this context, thermogravimetric analysis of plastic waste samples was carried out a...

Plasma-catalysis technologies (PCTs) have the potential to control the emissions of volatile organic compounds, although their low-energy efficiency is a bottleneck for their practical applications. A plasma-catalyst reactor filled with a CeO2/γ-Al2O3 catalyst was developed to decompose toluene with a high-energy efficiency enhanced by the elevatin...

In this study, commercial Ti-0.15Pd alloy could be activated by selective dissolution of Ti using simple HF treatment, to catalyze electrochemical dehalogenation of aqueous pollutants. The surface of dealloyed cathodes was characterized with a Pd-enriched nano-porous structure, as confirmed by scanning electron microscopy, glow discharge spectrosco...

Theoretical insights of the ultrasonic relaxation process in PbO–WO3–TeO2 glasses were investigated according to a model related to the propagation of ultrasonic waves in active two-well potential. The energy transfer of the ultrasonic waves either longitudinal or transverse to the glass network can create two-well potential based on the oxygen ato...
