The evolution of interfacial potentials as a function of CTAB concentration was characterized by surface and zeta potential measurements and complemented by molecular dynamic (MD) …
Web10 Feb 2024 · The magnitude of this enhancement is different from that of optical second harmonic generation (SHG). Recently, we produced nanostructure-covered laser-induced periodic surface structures (NC-LIPSSs) [11,12] and investigated their SHG [13,14,15]. We found that NC-LIPSSs could significantly modify the second-order nonlinearity of the …
