EXPLOITING ADVANCED ATMOSPHERIC AEROSOL CHARACTERISATION TO DEVELOP CUTTING-EDGE APPROACHES FOR SOURCE APPORTIONMENT
Atmospheric aerosols are very complex systems due to the huge variety of emission sources, size distributions, chemical properties, and transformation processes. Although the characterisation of atmospheric aerosols is still challenging, their study is essential since they have different impacts …

THE YIELDING TRANSITION IN SOFT AMORPHOUS SOLIDS UNDER OSCILLATORY SHEAR: FROM MICROSCOPIC REARRANGEMENTS TO MACROSCOPIC FAILURE
Complex fluids such as polymer solutions, colloidal suspensions, emulsions, or foams are ubiquitous in our daily lives. These soft materials often display a non-trivial response to mechanical perturbations, which depends both on the time scale and the amplitude of the applied perturbation. In …

A new prompt gamma spectroscopy-based approach for range verification in proton therapy
… whose benefits stem from both physical and biological properties. Ions deposit the maximum dose, i.e. the ratio between the energy absorbed by the tissue and its mass (Gy = J/k g), in a localized region close to the end of their range (called the Bragg Peak BP). The combination of the …

Surface Functionalizations towards Nucleic Acid Purification: a nanoscale study
Protein byosynthesis is performed by ribosomes, that translate the genetic information contained in a strand of mRNA and assemble the peptide chain. During translation, several ribosomes associate to a single strand of mRNA, forming supramolecular complexes known as polyribosomes (polysomes).This …

Degradation studies on different pigments and binders: new approaches to diagnostics in cultural heritage
Studying the state of degradation, alteration and conservation of an artwork is the starting point of a restoration process. This first step is commonly known in the field of cultural heritage as "diagnostics". A careful diagnosis allows choosing the best restoration approach for a sample under …

Large-scale neuronal networks: from simulation technology to the study of plasticity-driven cognitive processes
… which will pave the usage of these tools in medicine as support for novel therapies.

BUILDING A MODEL TO SIMULATE PROTEIN AGGREGATION AT ATOMISTIC DETAIL.
The project I have been focusing for the last three years was the development of a computational method to simulate protein aggregation into amyloids. As further described below, protein aggregation is a complex process leading to the accumulation and deposition of amyloid fibrils causing several …

Cholesterol-Dependent Cytolysins and Perforin: Similar Pore-Forming Mechanisms in Pathogenic Attack and Human Immune Defense
… that could have different implications on the biological mechanism of action of these pore-forming proteins. By electrophysiological measurements and atomic force microscopy technique on different artificial membrane, we are able to enrich the ring and the arc fraction and demonstrate that both …
