The formation of an opaque solid foam was induced by the direct interaction between tetraethyl orthosilicate (TEOS) and an ultrashort femtosecond laser source(Nd:glass, 527 nm, 10 Hz, 250 fs). The product, which resulted to be a silica xerogel, was characterized by different techniques. In particular, information about the morphology was obtained by scanning and transmission electron microscopy (SEM and TEM), while the presence of different functional groups was studied through IR measurements.

- Researchers developed a gold plasmonic bowtie nano-antennas array that can create extreme pressure (about 100 GPa) on a nanometer scale, using ultra-short laser pulses for precise control.
- This method utilizes non-linear interactions between photons and water molecules to generate a nano-plasma, resulting in extreme thermodynamic states without the complexity of current mechanical systems.
- The technique allows for the efficient creation of cavitation nano-bubbles and offers the potential to study the mechanical responses of cells and single molecules in ways that were previously difficult to achieve.
