Efficiency at maximum power of minimally nonlinear irreversible heat engines [PDF]
, 2012 We propose the minimally nonlinear irreversible heat engine as a new general theoretical model to study the efficiency at the maximum power $\eta^*$ of heat engines operating between the hot heat reservoir at the temperature $T_h$ and the cold one at ...

Harnessing Colloidal Dispersion for Laccase‐Driven Enzymatic Depolymerization of Polystyrene
Angewandte Chemie, EarlyView.Polystyrene (PS), long considered non‐degradable by biocatalytic pathways, can now be broken down under aqueous conditions using atmospheric air and a laccase–mediator system composed of a commercially available fungal enzyme and 1‐hydroxybenzotriazole as small organic mediator.

Single-atom heat machines enabled by energy quantization [PDF]
, 2018 Quantization of energy is a quintessential characteristic of quantum systems. Here we analyze its effects on the operation of Otto cycle heat machines and show that energy quantization alone may alter and increase machine performance in terms of output ...

Fourier Heat Conduction as a phenomenon described within the scope of the Second Law
, 2014 The historical development of the Carnot cycle necessitated the construction of isothermal and adiabatic pathways within the cycle that were also mechanically "reversible" which lead eventually to the Kelvin-Clausius development of the entropy function ...

Linear irreversible heat engines based on the local equilibrium assumptions [PDF]
, 2015 We formulate an endoreversible finite-time Carnot cycle model based on the assumptions of local equilibrium and constant energy flux, where the efficiency and the power are expressed in terms of the thermodynamic variables of the working substance.

Quantum heat engines with Carnot efficiency at maximum power
Physical Review Research, 2022 Heat engines constitute the major building blocks of modern technologies. However, conventional heat engines with higher power yield lesser efficiency and vice versa and respect various power-efficiency trade-off relations.

Quantum, cyclic and particle-exchange heat engines
, 2004 Differences between the thermodynamic behavior of the three-level amplifier (a quantum heat engine based on a thermally pumped laser) and the classical Carnot cycle are usually attributed to the essentially quantum or discrete nature of the former.
