Abstract:

Electron energy loss spectroscopy (EELS) in scanning transmission electron microscope (STEM) is a powerful tool for high-resolution chemical analysis. Various information can be obtained from EELS such as valence states and local coordination. Using small incident electron probe, STEM-EELS has the advantage to be recorded in atomic resolution, serving as a complementary tool for X-ray and neutron spectroscopy. In recent years, improvement of electron monochromator has enable nm-scale detection of plasmon and phonon excitation in nanomaterials and interfaces. These advantages have made STEM-EELS a synchrotron-like facility in the microscope.

In the presentation, I will start with the introduction and recent development of modern Cs-corrected electron microscope. Afterward, I will focus on the principle of STEM-EELS working for different energy range. Several examples, including structural, plasmonic and phonon studies, will be introduced. Finally, theoretical calculation of EELS using density functional theory (DFT) and neural network will be shortly explained.

Abstract:
We add a prognostic model of several naked, sweat-covered humans to each grid cell of ten different global climate models (GCMs), and we evaluate their core body temperatures every 15 minutes for the entirety of the 21st century in the RCP8.5 scenario. Designed to model the response to extreme heat, this model of human thermoregulation avoids the uncertain empirical relations used in other thermoregulation models, such as the skin blood flow rate and sweat rate. The model is validated against physiological data and its implementation in each GCM is bias-corrected to guarantee a match of historical simulations with ERA-5 reanalysis. Although simple and computationally efficient, the model accounts for longwave and shortwave fluxes, sensible and latent fluxes, body size and albedo, and the level of physical exertion. The resulting data reveal the places that will become uninhabitable by 2100 by different metrics, such as the occurrence of days during which it is lethal to work and/or rest in sun and/or shade.
