SMART-X: A Web Network of Ultrafast Science

Welcome to a series of four short popular science webinars from different institutes in Europe by Ph.D. students engaged in an Innovative Training Network on ultrafast science funded in the framework of the European HORIZON 2020 program. 

1. Laser-Fiction

Sambit Kumar Das, Fysikum, Stockholm University, Sweden

A laser is a monochromatic, directional, and coherent light beam of high intensity, based on the stimulated emission of electromagnetic radiation. Since their discovery, lasers have been a driving force in leading scientific research and discovery in various fields. At the same time, they also caught the attention of the public as a trademarked technology in science-fiction novels and comics. With the continuous advancement in laser technology, it always remains a question of intrigue, how far are we from those futuristic innovations? 

2. A Journey Through The Electromagnetic Spectrum

Lorenzo Restaino, Fysikum, Stockholm University, Sweden

We use electromagnetic energy whenever we tune our radio, watch TV, or heat food in a microwave oven. Electromagnetic energy travels in waves and spans a broad spectrum from very long radio waves to very short gamma rays. Only a small fraction of this spectrum, known as visible light, is visible to the human eye. We will explore the electromagnetic spectrum by looking at some everyday examples and some research applications.

3. Innovative Materials For Light Harvesting

Stavroula Vovla, Dipartimento di Fisica, Politecnico di Milano, Italy.

With conventional energy sources being depleted and causing heavy environmental damage, the need for alternative resources grows stronger. One potential candidate is solar power, which has attracted the interest of many scientific fields around the globe. Semiconductors are considered perfect candidates for light harvesting and storing devices. But are typical semiconductors like silicon able to cover our energy needs? What are some innovative materials and how do we study them?

4. Chemical Etching – The Artist’s Approach

Evgenia Symeonidou, Institute of Materials Science, National Center for Scientific Research Demokritos, Greece.

What happens when an acid “attacks” a metal? How is this connected to printmaking? And what does Rembrandt have to do with it all? Etching is a chemical redox reaction and is the common denominator in these three questions. Join this short journey to learn more about this widespread chemical process and to see what happens to an aluminum foil when dipped into an acidic solution!
