The aim of this work is focused on the L-lactide (LLT), a cyclic ester, an intermediate product in the synthesis of Poly(L-lactic acid) (PLLA) by polycondensation reaction from L-lactic acid; a monomer that allows synthesizing PLLA with high molar ma

Lactide dimer is an important monomer produced from lactic acid dehydration, followed by the prepolymer depolymerization process, and subsequent purification. As lactic acid is a chiral molecule, lactide can exist in three isomeric forms: L-, D-, and

The central part of the Galaxy hosts a multitude of stellar populations, including the spheroidal bulge stars, stars moved to the bulge through secular evolution of the bar, inner halo, inner thick disc, inner thin disc, as well as debris from past a

The APOGEE Open Cluster Chemical Abundances and Mapping (OCCAM) survey is used to probe the chemical evolution of the s-process element cerium in the Galactic disk. Cerium abundances were derived from measurements of Ce II lines in the APOGEE spectra

We are carrying out a large ancillary program with the SDSS-III, using the fiber-fed multi-object NIR APOGEE spectrograph, to obtain high-resolution H-band spectra of more than 1200 M dwarfs. These observations are used to measure spectroscopic rotat

The DEEP2 and COMBO-17 surveys are used to study the evolution of the luminosity function of red and blue galaxies to $z \sim 1$. Schechter function fits show that, since $z = 1$, $M^*_B$ dims by $\sim$ 1.3 mag per unit redshift for both color classe

We present the analysis of a sample of distant (z ~ 0.4 – 0.8) dusty starbursts selected by their ISOCAM-15 micra mid-infrared luminosities, for which we have obtained high resolution optical (LRIS, ESI) and near-infrared (NIRSPEC) spectroscopy wit
