Title: Scientific opportunities at the Brazilian synchrotron light laboratory (LNLS)

The LNLS has operated a synchrotron light source, the UVX, for more than 20 years. Since 2014, LNLS has been building a new source, the Sirius storage ring, which was successfully injected with a 3 GeV electron beam and is now under final commissioning stage. Sirius is a 4th generation light source with an unprecedent high brilliance that will open many scientific opportunities in many different fields. In this lecture, I will give the status of the Sirius project and first phase beamlines, highlighting the opportunities for nanoscience and nanotechnology research.
