- Abstract:
- ... The phase diagram of the system LiF–LuF₃ has been revised using thermal analysis. Specific heat capacity and enthalpy of phase transition and fusion were measured by differential scanning calorimetry for all compounds belonging to the system. A thermodynamic optimization of the LiF–LuF₃ phase diagram was performed by fitting the Gibbs energy functions to the experimental data that were taken from ...

Thermodynamic comparison of the selected adsorbents was carried out on the basis of the experimental measurement of the main thermo-physical parameters, such as specific heat, adsorption equilibrium curves and sorption enthalpy. A sens ...

- Abstract:
- ... The feasibility of radio frequency (RF) selective heating as a disinfestation technique was investigated, considering rusty grain beetle in bulk wheat samples at 27.12 MHz. Although pesticides and fumigants are the most commonly used methods for controlling insects in postharvest products such as grains, nuts, and fruits, they pose a direct threat to human health and the environment. In this work, ...

Eight salts, derived from tetrabutylammonium cation [N⁺ ₄₄₄₄] and inorganic anions like BF₄ ⁻, NO₃ ⁻, NO₂ ⁻, SCN⁻, BrO₃ ⁻, IO₃ ⁻, PF₆ ⁻ and HCO₃ ⁻ were synthesized using the ion exchange method. These ionic liquids (ILs) were characterized using thermogravimetry, differential scanning calorimetry and infrared spectroscopy. Thermophysical properties such as density, volume expansion, heat of fusion ...

- Abstract:
- ... Supercooled liquids are characterized by their fragility: The slowing down of the dynamics under cooling is more sudden and the jump of specific heat at the glass transition is generally larger in fragile liquids than in strong ones. Despite the importance of this quantity in classifying liquids, explaining what aspects of the microscopic structure controls fragility remains a challenge. Surprisin ...

- Abstract:
- ... The need for accurate thermodynamic data for the polychlorinated dibenzofuran family of isomers arises from the continued interest in the prediction of relative populations of these, and the lack of experimental data justifies the need for the calculation of these at a sufficiently accurate level. In order to add to the existing databases, specific heats have been calculated for the full 135 isome ...

- Abstract:
- ... In this study, thermal energy storage cement-based composite (TESC) was developed by incorporating paraffin/diatomite (DP) composite phase change material (PCM). Paraffin/DP composite PCM was firstly fabricated at mix proportion (paraffin: DP) of 0.9:1.0. Scanning electron microscope (SEM) and Fourier transform infrared (FT-IR) results show that paraffin can be well impregnated into DP pores and h ...

The radiant energy emitted in the range from UV to IR was collected by several photodiodes operating with high acquisition rate. The signal analysis showed the capability of the technique to capture the passage of coal streams an ...

- Abstract:
- ... Cryoablation for atrial fibrillation is a clinically approved technique used to control irregular heart rhythms due to abnormal electrical signals conducted from the pulmonary veins to the atria. The ablation catheter rapidly cools the cardiac tissue to freezing temperatures creating a discrete lesion which terminates these abnormal electrical pulses. Benefits of this approach include decreased ri ...

The thermodynamic study of vanadates is particularly interesting, as these compounds undergo multiple orbital and magnetic ordering transitions resulting in structural phase transitions as a function of temperature. The elastic and thermal properties have been computed by considering the intriguing temperature dependent structural phase transitions. A detailed investigation of lattice distortions, ...
