Special Issue Information

Dear Colleagues,

Basing on the success of the first edition of the Special Issue “Laser-Matter Interaction for Nanostructuration and Characterization: From Fundamentals to Sensing and Energy Applications”, we are glad to announce this Special Issue of Nanomaterials “Laser-Matter Interaction for Nanostructuration: From Fundamentals to Optical, Electrochemical, Magnetic and Electrical Quantum Sensing”.

Health care, global warming and climate change, sustainable energy production are key themes of the actual research. At the same time, nanomaterials represent one of the most important topics of 21st-century scientific and technological research. Thus, recent years have seen the exploitation of the nanomaterials potentialities in all the technological fields connected to human society challenges. Over the last few years, among the various fabrication methods, laser technology for nanoscale material synthesis and processing has seen an enormous development. In fact, the use of lasers has opened up new possibilities for material nanoprocessing because of a wide variety of nanostructures which can be obtained due to laser–matter interaction phenomena and controlling the laser process parameters.

Quantum sensing technology has become of enormous importance in recent years thanks to its particular versatility and unconventional responses, ranging from optical, electrochemical, magnetic and electrical sensing. For this Special Issue, we invite researchers to submit original research articles, letters, as well as review and prospective view articles on laser-matter interaction for nanostructuration applied to the production and characterization of quantum sensing materials.

Femtosecond high-intensity laser pulses at intensities surpassing 1014 W/cm2 can generate a diverse range of functional surface nanostructures. Achieving precise control over the production of these functional structures necessitates a thorough understanding of the surface morphology dynamics with nanometer-scale spatial resolution and picosecond-scale temporal resolution. In this study, we show that single XFEL pulses can elucidate structural changes on surfaces induced by laser-generated plasmas using grazing-incidence small-angle X-ray scattering (GISAXS). Using aluminium-coated multilayer samples we distinguish between sub-picosecond (ps) surface morphology dynamics and subsequent multi-ps subsurface density dynamics with nanometer-depth sensitivity. The observed subsurface density dynamics serve to validate advanced simulation models representing matter under extreme conditions. Our findings promise to open new avenues for laser material-nanoprocessing and high-energy-density science. Full article
