Engineering 2D spin networks by on-surface encapsulation of azafullerene radicals in nanotemplates.

We present an efficient strategy for on-surface engineering of organic metal-free supramolecular complexes with long-term spin protection. By vacuum deposition of azafullerene (CN) monomers on a pre-deposited template layer of [10]cycloparaphenylene ([10]CPP) nanohoops on Au(111) surface we exploit the molecular shape matching between the CN and [10]CPP for the azafullerene encapsulation with nanohoops in a guest-host complexation geometry. CN⊂[10]CPP supramolecular complexes self-assemble into an extended two-dimensional hexagonal lattice yielding a high density network of stable spin-1/2 radicals.

Oxygen-Promoted on-Surface Synthesis of Polyboroxine Molecules.

We present a protocol for the on-surface synthesis of polyboroxine molecules derived from boroxine molecules precursors. This process is promoted by oxygen species present on the Au(111) surface: oxygen atoms facilitate the detachment of naphthalene units of trinaphthyl-boroxine molecules and bridge two unsaturated boroxine centers to form a boroxine-O-boroxine chemical motif. X-ray spectroscopic characterization shows that, as the synthesis process proceeds, it progressively tunes the electronic properties of the interface, thus providing a promising route to control the electron level alignment.

Noncontact Layer Stabilization of Azafullerene Radicals: Route toward High-Spin-Density Surfaces.

We deposit azafullerene CN radicals in a vacuum on the Au(111) surface for layer thicknesses between 0.35 and 2.1 monolayers (ML).

Blue light therapy. An alternative approach for treatment of vascular skin ulcers.

Managing non-healing wounds is nowadays a challenging issue because of costly burden for each national health care system and the important disability of patients in terms of increased pain and decreased overall quality of life. Chronic skin lesions are usually stucked in the inflammatory phase of reparative cycle and defined from absence of a clinical improvement in a temporal span ranging from four weeks to three months. Improvement of wound microenviroment can play a leading role in the enhancement of chronic ulcers' healing process, as well as the standard care application on the basis of etiopathogenesis of ulcer.

Retrospective analysis of seroprevalence in a cohort of university students of Rome (Italy) between September 2020 and July 2021.

Background: the reopening of Universities in a COVID-19 pandemic context represented a potential source of virus transmission among students.

Objectives: to measure the SARS-CoV-2 real circulation among university students attending the University of Rome 'Niccolò Cusano' by seroprevalence analysis.

Design: retrospective study based on a point-of-care (POC) SARS-CoV-2 rapid qualitative serological screening performed on asymptomatic students attending the University.
