Cyclic Processes And Isolated Systems

2.9K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state. 
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Reversible and Irreversible Processes

4.6K
The thermodynamic processes can be classified into reversible and irreversible processes. The processes that can be restored to their initial state are called reversible processes. It is only possible if the process is in quasi-static equilibrium, i.e., it takes place in infinitesimally small steps, and the system remains at equilibrium However, these are ideal processes and do not occur naturally. An ideal system undergoing a reversible process is always in thermodynamic equilibrium within...

Entropy Change in Reversible Processes

2.7K
In the Carnot engine, which achieves the maximum efficiency between two reservoirs of fixed temperatures, the total change in entropy is zero. The observation can be generalized by considering any reversible cyclic process consisting of many Carnot cycles. Thus, it can be stated that the total entropy change of any ideal reversible cycle is zero.
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.

Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Deactivation Processes: Jablonski Diagram

Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

Summary

This study introduces token-driven totally asymmetric simple exclusion processes (TASEPs). Token binding kinetics and scarcity significantly impact particle flow and disorder propagation in these TASEP models.

Area of Science:

  • Statistical Mechanics
  • Complex Systems
  • Non-equilibrium Physics

Background:

  • Standard totally asymmetric simple exclusion processes (TASEPs) model particle movement on lattices.
  • Real-world particle dynamics, like molecular motors, are often mediated by external factors.

Purpose of the Study:

  • Investigate how token binding kinetics and scarcity influence TASEP current-density relations.
  • Analyze token-mediated disorder propagation and coupling of multiple TASEPs.
  • Extend findings to TASEPs with open boundaries.

Main Methods:

  • Theoretical analysis of token-driven TASEP dynamics.
  • Computational simulations to validate theoretical predictions.
  • Examination of various lattice configurations and boundary conditions.

Main Results:

  • Token binding kinetics and scarcity critically alter lattice current-density relationships.
  • Tokens effectively propagate local disorder across the entire lattice.
  • Shared token pools create coupling effects between concurrent TASEPs.

Conclusions:

  • Token-driven TASEPs provide a more realistic model for catalyzed or regulated particle transport.
  • This framework enhances understanding of biological and physical systems involving mediated particle motion.
  • The study bridges the gap between TASEP theory and experimental observations.
