We present a method for approximating thermodynamic parameters ΔG(P,T)°, ΔH, and ΔS for the cation exchange process in metal-organic frameworks, as exemplified by Ni(2+) exchange into Zn4O(1,4-benzenedicarboxylate)3 (MOF-5) and Co(2+) exchange into MOF-5 and Zn5Cl4(bis(1H-1,2,3-triazolo-[4,5-b],[4',5'-i])dibenzo-[1,4]-dioxin)3 (MFU-4l). For these examples, we find that the cation exchange proce...

A fixed bed reactor design program is developed by the use of Java JDK1.7 algorithm language with Eclipse program as the platform. The program selects five common fix bed reactor process flows to calculate the main structure parameters of the reactor. With the good interface, the program can output the corresponding results after inputting the kinetics and thermodynamics parameters of the react...

Entanglement entropy is often speculated as a strong candidate for the origin of the black-hole entropy. To judge whether this speculation is true or not, it is effective to investigate the whole structure of thermodynamics obtained from the entanglement entropy, rather than just to examine the apparent structure of the entropy alone or to compare it with that of the black hole entropy. It is b...

Mathematical simulation for the reciprocating compressor cycle incorporating the effects of common faults has been developed. The governing equations for different processes are derived by using first law of thermodynamics, continuity equation, equation of mass flow through valves, kinematic equation for piston movement and the cylinder heat transfer correlations. This paper gives the results o...
