A multipurpose thermal vacuum chamber for planetary research compatible with stand-off laser spectroscopies
Laserna-Vázquez, José Javier; Álvarez-Llamas, César; Purohit, Pablo; Moros-Portolés, Javier; Lucena, Patricia; Vadillo-Pérez, José Miguel[et al.] (2022)Stand-off spectroscopies and imaging techniques have gained a proper niche within the modern tools in remote compositional analysis for exploration in-situ planetary surface using rovers. Laser-induced breakdown spectrometry ... -
Attogram sensitivity through laser-induced breakdown spectroscopy of single optically-trapped nanoparticles
Purohit, Pablo; Laserna-Vázquez, José Javier (2017-07-10)Current trends in nanoengineering are bringing along new structures for usage over a wide variety of fields: from readily available products, e.g., clothes or foodstuff, to next-generation electronics or drugs. To suit ... -
Hyperspectral LIBS imaging of single-optically trapped particles
The interaction between discrete particles with laser-induced plasma presents some complexities that directly affects the analysis of bulk aerosols by LIBS. Single-particle analysis is not exempt of this kind of phenomena ... -
LIBS and Acoustic Measurements of Rocks and Regolith Found in the Traverse of the Perseverance Rover Across the Jezero Crater, Mars
Laserna-Vázquez, José Javier; Moros-Portolés, Javier; Álvarez-Llamas, César; Purohit, Pablo; Angel, S.M.; Bernardi, P.; Bousquet, O.; Cadu, A.; Chide, B.; Clavé, E.; Clegg, S.; Dauson, E.; Forni, O.; Fouchet, T.; Gasnault, O.; Jacob, X.; Lacombe, G.; Lanza, N.L.; Larmat, C.; Lasue, J.; Lorenz, R.D.; Meslin, P. -Y.; Montmessin, F.; Murdoch, N.; Ollila, A.M.; Pilleri, P.; Reyes-Newell, A. L.; Schroder, S.; Stott, A.; Cate, J. Ten; Vogt, D.; Maurice, S.; Wiens, R.C.; Mimoun, D.[et al.] (2022)The SuperCam instrument of the NASA MARS 2020 Perseverance rover combines a suite of atomic and molecular spectroscopies intended for an extensive description of rocks, soils and minerals in the surroundings of the landing ... -
OC-OT-LIBS: A novel approach to the chemical characterization of single particles
Spectral identification of individual micro- and nano-sized particles by the sequential intervention of optical catapulting, optical trapping and laser-induced breakdown spectroscopy is presented [1]. The three techniques ... -
Polydispersity and fractionation in laser ablation studied by LIBS in an optical trap
LIBS characterization of aerosols produced by laser ablation of bulk samples is strongly influenced by variations of physicohemical properties of the elements integrating the matrix. Among the consequences of these changes ... -
Spectral identification in the attogram regime through laser induced breakdown spectroscopy of single optically-trapped nanoparticles in air
Laserna-Vázquez, José Javier; Purohit, Pablo (2017-10-20)Current trends in nanoengineering are bringing along new structures of diverse chemical compositions that need to be meticulously defined to ensure their correct operation. Few methods can provide the sensitivity required ... -
Ultrafast laser excitation in atmospheric pressure optical traps for studying attogram mass nanoparticles.
Burgos-Palop, Clara; Purohit, Pablo; Fortes-Román, Francisco Javier; Laserna-Vázquez, José Javier (2023)Owing to the exceedingly small mass involved, complete elemental characterization of single nanoparticles demands a highly precise control of signal background and noise sources. LIBS has demonstrated remarkable merits for ... -
Understanding The Correlation Of Libs And Acoustic Measurements Of Rocks And Soils Found In The Traverse Of The Perseverance Rover Across The Jezero Crater, Mars
Laserna-Vázquez, José Javier; Álvarez-Llamas, César; Moros-Portolés, Javier; Purohit, Pablo; Angel, S.M.; Bernardi, P.; Beyssac, O.; Bousquet, B.; Cadu, A.; Chide, B.; Clavé, E.; Clegg, S.; Dauson, E.; Forni, O.; Fouchet, T.; Gasnault, O.; Jacob, X.; Lacombe, G.; Lanza, N.L.; Larmat, C.; Lasue, J.; Lorenz, R.D.; Meslin, P. -Y.; Montmessin, F.; Murdoch, N.; Ollila, A.M.; Pilleri, P.; Reyes-Newell, A.
