The present work aims to perform the drying kinetics of adzuki beans under different drying air temperatures, to adjust mathematical models to experimental data and to determine their thermodynamic properties. Drying kinetics were performed at 40, 50, 60, 70 and 80 °C at 1.5 m/s air velocity. Parry, Page and Handerson and Pabis mathematical models ...

The adsorption of bisphenol-A (BPA) on ordered mesoporous carbon (CMK-3) and modified CMK-3 (MCMK-3) for decontamination of aqueous medium was investigated. The CMK-3 and MCMK-3 materials had uniform pore sizes of 3.60 and 3.70 nm and high Brunauer-Emmett-Teller (BET) surface areas of 751 and 564 m2 g-1, respectively. The maximum adsorption capacit...
The thermal ageing of a silane-crosslinked polyethylene stabilised with 1 wt% of distearyl thiodipropionate (Irganox PS802) was studied in air at three different temperatures: 87 °C, 110 °C, and 130 °C. FTIR spectroscopy and DSC under O2 were used in a complementary way to monitor the antioxidant (AO) depletion during thermal ageing, but also to de...
The thermal decomposition of ethyl acetate was experimentally studied in a newly designed fast pyrolysis set-up. The results were compared to theoretical calculations and literature values in order to proof the experimental concept. The reaction was carried out in a free fall tubular reactor with a residence time of 0.15 s. The identification and q...

Inulinases are used for the production of high-fructose syrup and fructooligosaccharides, and are widely utilized in food and pharmaceutical industries. In this study, different carbon sources were screened for inulinase production by Aspergillus niger in shake flask fermentation. Optimum working conditions of the enzyme were determined. Additional...

Based on first principle calculation, activation of CO2 has been analyzed thoroughly by using different conceptual density functional theory based descriptors like reaction force, reaction force constant, reaction electronic flux, dual descriptor, etc. via dihydrogenation reaction of B3N3, H2 and CO2. The total reaction is a two-step reaction where...

We give a supplementary explanation for previous results about the exclusion of proton as well as hydronium (ion) transport through aquaporins (AQP1) via verified transition state theory by calculating the temperature-dependent viscosity for proton or hydronium (ion) transport through AQP1. We will demonstrate the temperature-dependent viscosity do...

NG-CT-10 and NG-CT-20 are newly developed grades of nuclear-grade graphite from China. In this study, their oxidation behaviors were experimentally investigated using thermal gravimetric analysis. Microstructural evolution before and after oxidation was investigated using scanning electron microscope, mercury intrusion, and Raman spectroscopy. The ...
