Has the Second Law of Thermodynamics Really Been Violated?

Some works have appeared in the recent accredited literature considering the possibility of macroscopic violations of the second law in simulated as well as actually executed experiments. We argue the inexistence of such violations in experiments based on the so‐called nonbias diode, demonstrating that the interpretation of the authors is flawed by a confusion between the concepts of thermal equilibrium and thermodynamic equilibrium. We also discuss an isomorphic experimental setup based on the evaporation‐condensation of a liquid in a closed atmosphere. Some critical observations are then made concerning recent attempts to reformulate classical equilibrium thermodynamics.
Keywords: thermodynamic equilibrium, violations of the second law, nonbias diode
