The Journal of Physiology, 2005 A recent article in The Journal of Physiology by Gueguen et al. (2005) shows that an efficient metabolic coupling between mitochondrial creatine kinase (mtCK) or adenylate kinase (AK2), and ADP rephosphorylation via mitochondrial respiration is tissue specific: it is functioning in skinned muscle of oxidative type I and type IIa but not in IIx type ...

Energy-Saving Strategies of Axial Flow Fans for Direct Dry Cooling System
Energies, 2021 The operating conditions of axial flow fans are closely related to the thermo-flow characteristics of the mechanical draft direct dry cooling system. Moreover, the uneven distribution of cooling air driven by axial flow fans may lead to the deterioration

Energy transfer in molecular devices [PDF]
Physical Review E, 2014 Protein machines often exhibit long range interplay between different sites in order to achieve their biological tasks. We investigate and characterize the non--linear energy localization and the basic mechanisms of energy transfer in protein devices.

Dexter energy transfer pathways [PDF]
Proceedings of the National Academy of Sciences, 2016 Significance Controlling the dynamics of excitons—including their transport, fission, fusion, and free carrier generation—presents a central challenge in energy science, optoelectronics, and photobiology. We develop a coupling-pathway theory for triplet energy transfer, a process controlled by the structure of the medium between donor

Experimental Study on Heat Loss of a Single Screw Expander for an Organic Rankine Cycle System
Frontiers in Energy Research, 2020 For displacement expanders, the irreversible losses include leakage, friction, heat dissipation, and flow resistance. Currently, the research on the heat loss of expanders is scarce, especially with regards to experimental studies.

Performance Study on a Single-Screw Expander for a Small-Scale Pressure Recovery System
Energies, 2016 A single-screw expander with 195 mm diameter is developed to recover pressure energy in letdown stations. An experiment system is established using compressed air as a working fluid instead of natural gas.
