Carlo Lamberti, born in 1964, takes his degree thesis in Physics in 1988 with a thesis in the field of many body physics (110/110 cum Laude) in the Turin University. In the 1988-1993 period he worked in the CSELT laboratories Torino Italy, (at that time Telecom Italia, then Avago Technologies) on the characterization of the interfaces of III-V semiconductor heterostructures with 4K photoluminescence, high resolution XRD and X-ray absorption spectroscopies (XAS at synchrotron radiation sources). He presented his PhD defense in solid state physics on this topic in Rome in September 1993. Since 2006 he is associate professor in Physical Chemistry at the Torino University. He is the Italian coordinator of the MaMaSELF project since the beginning (2007).
He is an expert in the techniques based on Synchrotron Radiation and Neutrons beams in the characterization of materials. He and his team performed in the last 20 years more than 200 experiments approved by international committees on the following large scale facilities, ADONE (Frascati, I), LURE DCI and SuperACO (Orasay, Paris, F), ESRF (Grenoble, F), Elettra (Trieste, I), SRS (Daresbury, UK), SLS (Villigen, CH), APS (Argonne, IL, USA), SOLEIL (Orsay, F), MAX II, (Lund, Swedwen), Diamond and ISIS (Didcot, UK), ILL (Grenoble, F), SINQ (Villigen, CH), FRM-II (München, D) among them two Long Time projects at the ESRF.
He authored and co-authored: (i) more than 300 research articles and letters appeared on the most important journals in the field of Physics, Chemistry and Materials Science;
He is the Principal Investigator of the Mega-grant No. 14.Y26.31.0001 of the Russian Federation Government to support scientific research Southern Federal University (MaMaSELF partner) where, for the 2014-16 period, he has the position of full professor in solid state physics and is the Scientific Director of the “Smart Materials” Center.

Metal Nanoparticles and related supports
We investigated the transformation of Pd-acetate precursors into Pd metal nanoparticles supported on highly cross-linked porous polymers by extending the study from poly(4-ethylstyrene-co-divinylbenzene), hereafter PS, to poly(4-vinylpyridine-co-divinylbenzene), hereafter P4VP. In both studies Pd2+ ® Pd0 reduction was performed using H2 or CO reducing gents and we investigated by means of simultaneous XANES/SAXS data collection at the synchrotron (ESRF, BM26A) supported by parallel IR and TEM analyses at the lab, see Figure 1. We have demonstrated that the nature of the polymeric matrix has a strong influence on the formation of the Pd NPs and affects their final properties, in terms of particle size, electronic properties, and type and fraction of accessible surface sites. In particular, the presence of nitrogen-based ligands allows the formation of extremely small, subnanometric Pd clusters in P4VP, as demonstrated by the observation of a specific interaction between Pd nanoparticles and the nitrogen of the pyridine ligands. For both systems, the reduction process is strongly dependent on the nature of the reduction agent (H2 or CO).

Ziegler−Natta polymerization catalysts
We performed a systematic investigation of heterogeneous Ziegler−Natta (ZN) catalysts industrially relevant for polyethylene production, which are based on titanium and magnesium chloride tetrahydrofuranates (Figure 4, left). The structural, vibrational, and electronic properties were investigated in detail by means of a multi-technical approach at each step of catalyst preparation, including pre-catalyst activation. In particular, we combined in situ XAS and XES experiments (performed at BM26 and ID26 beamlines at ESRF, respectively) with XRD, DR UV-Vis and IR (both Mid-IR and Far-IR) measurements.
Metal organic frameworks (MOFs).
We succeeded in the functionalization of UiO-67 MOF with different M metals (M = Pt, Cu, Rh, Ir). An operando EXAFS experiment, fluxing H2/He, allowed us to follow the reduction of Pt2+ to Pt0 by EXAFS (cleavage of the Pt−Cl bonds (green path in Figure 5a), generating coordination vacancies on platinum sites. The large pore size of UiO-67 allows for ligand exchange between 2 Cl− and even bulky ligands such as toluene-3,4-dithiol (H2tdt, ligand exchange path in Figure 5a). Framework bpydcPt(II)Cl2 complexes can also be oxidized at room temperature to bpydcPt(IV)Br4 through oxidative addition of liquid Br2 (oxidation path in Figure:
