Title: Energy and Environment

Abstract: Among the renewable technologies, the wind is a prominent source of energy and synchronizing its share in global energy production market remarkably. Considering this context, in the last decades, there has been a fast growth and spread of renewable energy plants. Among them, wind generators are the most widespread type of intermittent renewable energy harvesters with their 539 GW of cumulative installed power at the end of 2017. Wind capacity, i.e. total installed power, is keeping a positive trend with an increase of 52.5 GW in 2017. In the future, such growth could decrease due to saturation of in-land windy areas that are suitable for installations.

    Today, we will light-upon the emerging wind technologies considering their potential contribution, up to date challenges, environmental impacts, applications, and technology inclination and in what way they might evolve in the future. These technologies were identified as originating primarily from the academic sector, some start-up companies and a few larger industrial entities. The following capacities were deliberated: offshore floating concepts, airborne wind energy (AWE), smart rotors techniques, blade tip-mounted rotors, novel blade manufacturing techniques, multi-rotor turbines, wind-induced energy harvesting strategies, unconventional electricity transmission systems, alternative support structures, modular high-voltage direct-current generators, diffuser-augmented turbines and small-scale turbine technologies. The future role of advanced multiscale modelling and data availability is also considered. This talk is highlighting that more research will be required to realize many of these emerging technologies. However, there is a dire need to highlight the interactions between fundamental and industrial requirements by properly approaching public and private financing in these emerging wind technologies as industrial growth might outpace further fundamental study earlier than anticipated.

Title: Energy Nanomaterials at atomic scale: from growth mechanisms to local properties

Abstract: Technology at the nanoscale has become one of the main challenges in science as new physical effects appear and can be modulated at will. Materials for spintronics, electronics, optoelectronics, sensing, energy applications and new generations of functionalized materials are taking advantage of the low dimensionality, improving their properties and opening a new range of applications. As developments in materials science are pushing to the size limits of physics and chemistry, there is a critical need for understanding the origin of these unique physical properties (optical and electronic) and relate them to the changes originated at the atomic scale, e.g.: linked to changes in (electronic) structure of the material. In the present work, I will show how combining advanced electron microscopy imaging with related spectroscopies in an aberration corrected STEM will allow us to probe the elemental composition and electronic structure simultaneously with the optical properties in unprecedented spatial detail.

The talk will focus on several examples in advanced nanomaterials for optical, plasmonic and energy applications. In this way the latest results obtained by my group on direct Visualizing and modeling materials at atomic scale will help to understand their growth mechanisms (sometimes complex) and also correlate their physical properties (electronic and photonic) at sub-nanometer with their atomic scale structure. The examples will cover a wide range of nanomaterials: quantum structures self-assembled in a nanowire: quantum wires (1D) and quantum dots (0D) and other complex nanowire-like morphologies for photonic and energy applications (quantum computing, single photon emitters, water splitting cells, batteries), nanomembranes and 2D sheets.
