Thermodynamics of the System of Distinguishable Particles

open access: yesEntropy, 2009
The issue of the thermodynamics of a system of distinguishable particles is discussed in this paper. In constructing the statistical mechanics of distinguishable particles from the definition of Boltzmann entropy, it is found that the entropy is not ...

Clausius versus Sackur-Tetrode entropies [PDF]

open access: yes, 2013
Based on the property of extensivity (mathematically, homogeneity of first degree), we derive in a mathematically consistent manner the explicit expressions of the chemical potential $\mu$ and the Clausius entropy $S$ for the case of monoatomic ideal ...

On the proper treatment of improper distributions [PDF]

open access: yes, 2017
The axiomatic foundation of probability theory presented by Kolmogorov has been the basis of modern theory for probability and statistics. In certain applications it is, however, necessary or convenient to allow improper (unbounded) distributions, which ...

The Nature of the Chemical Process. 1. Symmetry Evolution - Revised Information Theory, Similarity Principle and Ugly Symmetry [PDF]

open access: yes, 2001
Three laws of information theory have been proposed. Labeling by introducing nonsymmetry and formatting by introducing symmetry are defined. The function L (L=lnw, w is the number of microstates, or the sum of entropy and information, L=S+I) of the ...

On the M\"uller paradox for thermal-incompressible media [PDF]

open access: yes, 2011
In his monograph Thermodynamics, I. M\"uller proves that for incompressible media the volume does not change with the temperature. This M\"uller paradox yields an incompatibility between experimental evidence and the entropy principle.

Distinguishability in Entropy Calculations: Chemical Reactions, Conformational and Residual Entropy

open access: yesEntropy, 2011
By analyzing different examples of practical entropy calculations and using concepts such as conformational and residual entropies, I show herein that experimental calorimetric entropies of single molecules can be theoretically reproduced considering ...

In Situ Construction of Cu1+/Cu0 and Cu2+/Cu0 Pairs of Cu‐Based Catalysts for Electrocatalytic Nitrate Reduction

open access: yesAdvanced Science, EarlyView.
CuO and CuPO (Cu2P2O7 and Cu3(PO4)2) as precursors are in suit construction two distinct copper‐based active sites during the NO3RR reaction: Cu1+/Cu0 (derived from CuO) and Cu2+/Cu0 (derived from CuPO). Cu1+/Cu0 is the key to achieving high activity and high selectivity.

Some Observations on the Concepts of Information-Theoretic Entropy and Randomness

open access: yesEntropy, 2001
: Certain aspects of the history, derivation, and physical application of the information-theoretic entropy concept are discussed. Pre-dating Shannon, the concept is traced back to Pauli.

Room‐Temperature Alane Dehydrogenation for Visible‐Light‐Driven Photocatalytic Hydrogen Supply System

open access: yesAdvanced Science, EarlyView.
In situ formed Al/MOF enables viable visible‐light‐driven photocatalytic dehydrogenation of alane (AlH3) confirming practical application. Results demonstrate that Al nanoparticles prolong lifetime of photogenerated charge carriers via localized surface plasmon resonance induced hot electron injection, while AlH3 chemisorption triggers interfacial ...
