The shift factor data deviates from the WLF or VTFH equation for temperatures below T g. In addition, we find that the normalized rate of approach is the same for volume and enthalpy recovery at 97°C in the limit of a linear temperature jump, but it differs between the two properties ...
High-entropy ceramics is an emerging, yet blooming class of materials owing to its ever-growing set of applications, such as thermal barrier protection, wear- and corrosion-resistant coatings, thermoelectrics, batteries and catalysts1,2. They stand out for their mechanical properties, thermal and ch...

Above equation contains (next to the variable temperature, T, and the degree of aggregation, Φn) three parameters; i.e.theenthalpyofelongation he, the elongation temperature Te (the temperature at which the self-assembly starts) and the parameter ΦSAT, which is introduced[...] ...
The statics equation of compressible fluid, i.e. potential enthalpy (energy + enthalpy) balance law (Ling Wen) pointed out that in the gravitational field, the same quality of liquid which has potential enthalpy were the same constant, which means that when the value of enthalpy when (low ...

Calculations of the enthalpy of dimerization to give tricyclic compound 70 (Equation 3) showed it to be a highly endothermic process, with ΔH=+32.6kcalmol−1. From: Comprehensive Heterocyclic Chemistry III, 2008 Related terms: Dimerization Polyimide Macromolecule Phthalocyanine N-Heterocyclic Carbene...
These results prove that potential enthalpy is the quantity whose advection and diffusion is equivalent to advection and diffusion of heat in the ocean. That is, it is proven that to very high accuracy, the first law of thermodynamics in the ocean is the conservation equation of potential ...
Values of ΔGden0′ can then be obtained from Keq(den)0′ and the Gibbs equation (1.1)ΔGden0′=−RTln(Keq(den)0′) where R is the gas constant and T is the absolute temperature. Backbone amide 1H exchange can be used to assess Keq(den)0′ at the level of individual amino ...
by standard material KCl, solution enthalpies at different molalities of five kinds of ILs [CnPy][HSO4](n=2, 3, 4, 5, 6) were also determined, and the molar solution enthalpies at the infinite dilution and relative parameters were also obtained by application of Pitzer’s equation. ...
