In this seminar, I will present the MARTINI platform, dedicated to stellar evolution and multi-messenger astronomy. MARTINI builds upon FRUITY, extending its original focus beyond just Asymptotic Giant Branch stars. I will first cover our latest results regarding the s-process, and then share our preliminary findings on Neutron Star Merger models and the related r-process. I will conclude by discussing the atomic data and opacities needed to model kilonova light curves, emphasizing our collaborations with nuclear experiments such as PANDORA and n_TOF.
