We analyzed the effect of the interfacial free energy on the thermodynamics of hydrogen sorption in nano-scaled materials. When the enthalpy and entropy terms are the same for all interfaces, as in an isotropic bi-phasic system, one obtains a compensation... see more

The liquid-phase enthalpy of mixing for Al–Tb alloys is measured for 3, 5, 8, 10, and 20 at% Tb at selected temperatures in the range from 1364 to 1439 K. Methods include isothermal solution calorimetry and isoperibolic electromagnetic levitation drop cal... see more

Gen-Z is digital natives with unique learning styles. Gen Z is attracted to mobile technology and interactive visual learning materials. Therefore, the mobile game application seems to engage Gen Z in learning abstract chemistry topics. This paper focuses... see more

This report presents the N–H and O–H bond dissociation energies (BDEs) and enthalpies (BDEts) of 27 para-substituted anilines and phenols using Density Functional Theory (DFT) with functional wB97X-D and basis set 6-31G**. The computed BDEs/ BDEts show a ... see more

This study aimed to investigate the retrogradation rate of heat moisture treated sago and arenga starches using different approaches, including a thermal approach using DSC (differential scanning calorimetry), a rheological approach using dynamic viscoela... see more

Energy can’t be created and can’t be destroyed but energy can be transformed from one energy into another. The success rate of energy change is called efficiency. The success of a steam turbine certainly can’t be separated from the level of efficiency and... see more

Drying of agricultural products at high temperatures can be simulated by mathematical models, which intend to describe the drying process close to commercial patterns. They are based on simultaneous heat and mass transfer between the product that is losin... see more

The solidification phenomenon is present in the casting process of energetic materials. In defence industry, trinitrotoluene (TNT) is used as main charge for high explosive ammunitions. The present study tackles the numerical simulation of the solidificat... see more

To be able to pre-select new working fluids for absorption refrigeration systems, it is necessary to have a good understanding in the calculation or correlation of thermophysical properties of working fluids.  The choice of the most appropriate therm... see more
