Programme

8.45-9.00 Welcome speech of Paolo Tosi (Head of the Atomic & Molecular Physics Group)

9.00-9.55 First Session (Leonardo Ricci)

Diana Elisa Chiari

Permutation Entropy: one tool, multiple applications
The speaker will introduce a new method of non-linear analysis of complex systems, Permutation Entropy, and its applications in biology and plasma physics.

Alessio Perinelli

Investigating the embedding lattice
Depending on the embedding applied to a time series, distinct vector distance distributions arise: characterising the mutual relation between these distributions by means of their Kolmogorov-Smirnov statistic is the first step towards a possible objective criterion for optimal embedding.

9.55-10.25 Second Session (Daniela Ascenzi)

Andrea Cernuto

Reactive Scattering and Astrochemistry: Ion-Neutral reactions at work
A brief overview of experimental and theoretical methods for studying ion-neutral reactions of astrophysical interest.

10.25-10.45 Coffee Break

10.45-11.15 Third Session (Mario Scotoni)

Maddalena Bertolla

Looking and sensing an interlaced yarn
The talk will be about the study of the so-called “interlacing process”, that causes the formation of knots in a yarn. The process is investigated using a visual approach and a vibrational analysis.

11.15-13.00 Fourth Session (Paolo Tosi)

Giorgio Dilecce

Non-equilibrium in action
How and why the strong non-equilibrium in electric discharges is so important in many technological applications.

Sara Lovascio

Plasma-catalysis processes for CO2 reforming of methane
An introduction to plasma dry reforming coupled to catalysis, and to the ongoing research on the CO2 conversion by nanosecond discharges.

Luca Matteo Martini

Laser-induced fluorescence in atmospheric pressure discharges
The detection of transient species in atmospheric pressure discharges requires selectivity, sensitivity, and high time- and space-resolution. Laser-induced fluorescence is the technique of choice.

Nicola Gatti

Assessing the non-equilibrium: vibrational and rotational temperature profiles in N2 and N2-CO2 microwave plasma from laser Raman scattering
Raman spectroscopy is applied to investigate a microwave plasma used to activate N2 and CO2. By this technique, radial/axial profiles of rotational and vibrational temperature are obtained. They show peak values of 4000 K and 10000 K, respectively.
