According to the Hume-Rothery rules, the incorporation of solute atoms into a multicomponent solid solution will not disturb the crystal structure of the parent phase. Therefore, it is believed by some that the mixing enthalpy of high-entropy alloys, in addition to the atomic size difference and...
Some the negative value of enthalpy (∆H) is shown which indicates an exothermic process [58]. The positive value of ∆S revealed an increasing disorder and randomness at the solid-solution interface during the adsorption process due to adsorption and subsequent desorption [7,12,61,94,98]....
Physical networks typically employ enthalpy-dominated crosslinking interactions that become more dynamic at elevated temperatures, leading to network softening. Moreover, standard mathematical frameworks such as time-temperature superposition assume netw
The binding between a protein and a ligand has both enthalpic and entropic contributions, where the change in enthalpy is determined by a variety of interatomic forces, including electrostatic, van der Waals, and hydrogen-bonding interactions, and the entropic contribution represents the change in the...
