Prediction of underwater residual lung volume in healthy men and women.

Clin Physiol Funct Imaging 2021 Jun 11. Epub 2021 Jun 11.

Department of Kinesiology, University of Alabama, Tuscaloosa, AL, USA.

Regression equations are commonly used to predict residual lung volume (RV) during underwater weighing when measurement is not practical. However, the equations currently available were derived from on-land measures of RV and may account for changes in lung capacity during submersion, thus leading to inaccuracies in assessment of percent body fat (%BF). The purpose of this study was to 1) develop a new equation (RV ) for the prediction of underwater RV, 2) cross-validate RV and compare it to existing RV equations, and 3) compare the effects of RV and existing equations on underwater %BF.

Self-Constructed Multiple Plasmonic Hotspots on an Individual Fractal to Amplify Broadband Hot Electron Generation.

ACS Nano 2021 Jun 11. Epub 2021 Jun 11.

School of Materials Science and Engineering, Tianjin University, Tianjin 300350, P.R. China.

Plasmonic nanoparticles are ideal candidates for hot-electron-assisted applications, but their narrow resonance region and limited hotspot number hindered the energy utilization of broadband solar energy. Inspired by tree branches, we designed and chemically synthesized silver fractals, which enable self-constructed hotspots and multiple plasmonic resonances, extending the broadband generation of hot electrons for better matching with the solar radiation spectrum. We directly revealed the plasmonic origin, the spatial distribution, and the decay dynamics of hot electrons on the single-particle level by using simulation, dark-field spectroscopy, pump-probe measurements, and electron energy loss spectroscopy.
