Introduction: Lung transplant (LT) is the ultimate option for end-stage lung diseases. Malnutrition and sarcopenia, common in LT recipients, can be reversible with adequate exercise and nutrition. This study aims to assess changes in physical performance and aerobic capacity after a 10-week rehabilitation program (RP) in LT recipients, as well as to describe the prevalence of sarcopenia and malnutrition before and after RP and their influence on clinically relevant outcomes.

In this study, we investigate the thermal magnetic behavior of a thick film composed of assembled FeRh nanoclusters preformed in the gas phase. This work reveals a broad and asymmetric metamagnetic transition with a consequent residual magnetization at low temperature.

These dopants vary as much by their ionic size, as by their electronic valence and some of them have been used in ZnO due to their known magnetic and/or optical properties. The chemical nature of the dopants controls their ability to incorporate into ZnO crystal lattice.

Electron-lattice scattering rate is shown to increase with size reduction, in agreement with our previous results obtained on gold and silver nanoparticles in the low excitation regime.

Among the possible candidates, Ga-doped ZnO nanocrystals are particularly suited for mid IR, considering their wide range of possible doping levels and thus of plasmon tuning. In the present work, we report on the tunable mid IR plasmon induced in degenerate Ga-doped ZnO nanocrystals.
