Nanoscale Materials Laboratory
Welcome to the Nanoscale Materials LabThe Nanoscale Materials Laboratory, established on the basis of an agreement by the Department of Physics of the University of Trieste (Department of Excellence 2023-2027) and Elettra, hosts researchers and students carrying out experiments in the fields of Surfaces, 2D Materials and Atomic Clusters Physics, in close collaboration with scientists from Elettra. Besides the other instruments the nmLab host the size-selected nanocluster source ENAC (Exact Number of Atoms in each Cluster). The nmLAB is associated to the National Quantum Science and Technology Institute funded within the PNRR. Since 2000 more than 80 students have carried out experimental work in the lab in preparation of their Master's degree thesis in Physics, as well as in the framework of the PhD in Nanotechnology and Physics. The Lab hosts also the Training Activity of the course Laboratory of Nanomaterials Physics for the undergraduate students in Physics of UniTS. |

Challanges in the oxidation at the sub-nanoscaleAt the sub-nanometric scale, determining oxidation states becomes increasingly complex, as the properties of matter are strongly influenced by the discrete number of atoms involved. 
Oxygen on the top of the smallest mountainDue to the corrugation of graphene and the electronic structure of matter on the sub-nanometer scale, oxygen only adsorbs on top of very small size-selected Pt clusters 
The smallest Silver oxideSurprisingly bulk-like structural motifs appear in Silver-oxides already in the sub-nanoscale regime. Thanks to the new size-selected cluster source developed in the Lab we measured at the SuperESCA beamline the unusual process of Ag oxidation at T=20 K. 
Unusual reversibility of molecular break-upPentacene molecules adsorbed on Ir(111) can undergo a reversible deydrogenation process that can be engineered to produce polyacenes, via on-surface synthesis. 
Epitaxial graphene boosts photocatalysis in titania nanoparticlesThe choice of an interfacial layer of epitaxial graphene to support titania nanoparticles has been revealed as a key ingredient to dramatically increase their capability to split water and produce hydrogen. 
It's a matter of transparency to van der Waals forcesThe van der Waals interactions between light adsorbates with polar (Carbon Monoxide) and non-polar (Argon) character and a metal surface are partially screened by graphene which shows a translucency parameter equal to 0.507. 
Ultra-fast atomic diffusion on grapheneUltra-low atomic diffusion barrier of Pt atoms on graphene was determined by combining High-Resolution XPS and DFT

Una bella chiacchierata su RADIO CAPODISTRIA
Una bella e lunga chiacchierata insieme a Rosanna Bubola per "Calle degli Orti grandi" a parlare di Elettra e della nostra adorata ENAC, per trasmettere un po' l'amore in quel che facciamo e per quello che esploriamo.
(in italiano)
Andrea: one of those who truly love this work and always give their very best! Well done Andrea !
1 September
Proud of our PhD students !
Andrea is back from the ECOSS 38 Conference, which this year was held in Braga, Portugal, with a wonderful gift: the special recgnition of “Honorable Mention” for the seminar he gave, presenting our very latest results on FeS₂ growth.

Press Highlights
Our latest results, published in the Journal of the American Chemical Society, concerning the limitations in understanding the oxidation state of matter at the sub-nanometric scale, have also been highlighted in the Press in recent days.
20-25 July
ICESS-16 in Berkley: we are present !
In the vibrant and captivating atmosphere of Berkeley, the 16th edition of the ICESS conference took place, where Deborah Perco presented the results of our recent work published in JACS, dedicated to the study of the oxidation process of sub-nanometric clusters and entitled "Limitations in Determining Oxidation States in Condensed Matter at the Sub-Nanometric Scale"
