Quantum-Classical Transition of Photon-Carnot Engine Induced by Quantum Decoherence

open access: yes, 2005
We study the physical implementation of the Photon Carnot engine (PCE) based on the cavity QED system [M. Scully et al, Science, \textbf{299}, 862 (2003)]. Here, we analyze two decoherence mechanisms for the more practical systems of PCE, the dissipation

Adsorption and desorption of polycarboxylate ether superplasticizer in fresh cementitious materials blended with mineral admixtures

open access: yesJournal of Materials Research and Technology, 2022
The adsorption behavior of polycarboxylate ether (PCE) superplasticizer in fresh cement-based materials has been well investigated, but its desorption behavior was little reported. To facilitate deeper understanding the dispersion effect of PCE on binder
