From the sea bottom to the red planet with laser-induced breakdown spectroscopy
(2016-03-04)Laser-induced breakdown spectroscopy (LIBS) constitutes one of the most active research fields in analytical science. Among several important features, ability for adaptation to radically different scenarios constitutes ... -
Fs-Time Resolved Microscopy as a tool for monitoring laser-matter interaction
(2015-09-03)Femtosecond laser pulses provides the advantage in comparison with longer pulses that there is no interaction between laser and plasma. Moreover, the applied energy is deposited in much less time than nanosecond pulses, ... -
Geochemical Analysis of Ronda Peridotite: Insights into Martian Analogues and Alteration Processes.
(2024)In the context of the geochemical characterization of potential Martian analogues on Earth, a peridotite sample from Serranía de Ronda (Málaga, Spain) was analyzed. The peridotites of Ronda are distinguished by the prevalent ... -
