[institut] [phys4phys] IPB seminar: Aleksandar Milosavljević, Friday, 14 August, 12:00

[Nenad Vukmirovic]

Dear colleagues,

You are cordially invited to the Institute of Physics Belgrade seminar, 
which will be held on Friday, 14 August 2026 at 12:00 in the library 
reading room "Dr. Dragan Popović" of the Institute of Physics Belgrade. 
The talk entitled

On-the-fly soft X-ray spectroscopies of isolated and solvated 
nanoparticles: probing metal–molecule interfaces on plasmonic 
nanoparticles and exploring new photovoltaic nanomaterials

will be given by Dr Aleksandar Milosavljević (Synchrotron Soleil, 
France). The abstract of the talk:

A state-of-the-art experimental setup at the PLEIADES beamline (SOLEIL 
Synchrotron, France) for X-ray Aerosol Photoelectron Spectroscopy (XAPS) 
of nanoparticles isolated in vacuum will be presented [1,2]. The 
nanoparticle beam is generated from a colloidal solution, focused by an 
aerodynamic lens, and crossed with the photon beam in front of a 
hemispherical analyzer. This arrangement offers several advantages over 
table-top techniques: it completely avoids substrate influence and 
radiation damage, allows direct alignment to the vacuum level [3], and 
enables depth profiling via tunable photon energy. Moreover, using soft 
X-rays provides exceptional sensitivity to the nanoparticle surface.

I will present and discuss recent results related to the electronic 
structure of new photovoltaic materials [2] and light-induced chemistry 
on functionalized metallic plasmonic nanomaterials [4]. I will briefly 
discuss perspectives on combining XAPS with liquid jet spectroscopy on 
PLEIADES, utilizing mass/charge-selected X-ray spectroscopy to 
investigate ligands alone, and probing light-activated nanoparticles in 
situ.

This activity is supported by the Science Fund of the Republic of 
Serbia, #Grant No. 230, Aerosols of copper-silver based nanomaterials 
for absorbers in solar cells - Aerosol4solar.
