Homochirality as a Consequence of Thermodynamic Equilibrium?

Chemistry – A European Journal, 2006
AbstractRecent results on the crystallisation/dissolution equilibrium of enantiomorphic crystals of NaClO3 lead to the conclusion that liquid‐phase systems composed of achiral or fast racemising compounds yielding enantiomorphic solid phases (racemic conglomerates) can derive spontaneously to a single homochiral solid phase. This is a thermodynamically

Adsorption Equilibrium, Kinetics, and Thermodynamic Studies of Fluoride Adsorbed by Tetrametallic Oxide Adsorbent

, 2018
This study investigated the performance of fluoride adsorption onto a specific tetrametallic oxide adsorbent Fe–Al–Ce-Ni (FACN) and the effect of temperature on adsorption performance.

Thermodynamics and Equilibrium

2012
The concept of the equilibrium state of a system is of utmost importance in analytical chemistry. To illustrate this assertion briefly, recall that numerous chemical reactions are performed with analytical goals in mind. The conclusions they provide can be easily reached if and only if the reactions proceed through to their natural completion, that is,

Thermodynamics and Equilibrium

2010
Thermodynamics takes its name from the Greek for ‘movement of heat’ and is the science concerned with the interchange of energy, particularly that between thermal energy and mechanical work. Thermodynamics is concerned with systems which have come to equilibrium and not with the rate at which equilibrium is achieved.

Elimination of carbon vacancies in 4H-SiC employing thermodynamic equilibrium conditions at moderate temperatures

, 2015
The carbon vacancy (VC) is a major point defect in high-purity 4H-SiC epitaxial layers limiting the minority charge carrier lifetime. In layers grown by chemical vapor deposition techniques, the VC concentration is typically in the range of 1012 cm−3 ...

Adsorptive Removal of Toxic Dye Using Fe3O4–TSC Nanocomposite: Equilibrium, Kinetic, and Thermodynamic Studies

, 2016
Herein, trisodium citrate based magnetite nanocomposite (Fe3O4–TSC) was used for malachite green (MG) dye expulsion from aqueous medium. The adsorption tests were executed at different parameters. The maximum adsorption were took place at pH 4 in 40 min.

Canonical dynamics: Equilibrium phase-space distributions.

Physical review. A, General physics, 1985
Nose has modified Newtonian dynamics so as to reproduce both the canonical and the isothermal-isobaric probability densities in the phase space of an N-body system.

Non-equilibrium Thermodynamics

2013
In the preceding chapters with few exceptions we studied systems at equilibrium. This means that the systems do not change or evolve over time.

Equilibrium Thermodynamics

1983
Equilibrium Thermodynamics gives a comprehensive but concise course in the fundamentals of classical thermodynamics. Although the subject is essentially classical in nature, illustrative material is drawn widely from modern physics and free use is made of microscopic ideas to illuminate it.
