Summary: Laser-based methods are effective in fabricating surface micro- and nanostructures, particularly through the formation of LIPSS for linear structures. By using a combination of pulses at different wavelengths and polarization orientations, different geometries of nanostructures can be obtained.

Summary: The study found that UV-C irradiation had a significant impact on the structural quality of a-C:H and ta-C:H films, reducing the content of sp(3) and oxygen-containing radicals. The influence of UV-C light directed almost parallel to the films' surface on the structural quality of graphene-like films was slightly higher than that directed perpendicular.

Summary: Femtosecond laser was used to create periodic nanostructures on titanium surface, improving its corrosion resistance. The influence of these induced structures on titanium's corrosion resistance was investigated. The study systematically examined the micro-morphology, wetting, microstructural features, and corrosion behavior of the titanium surface before and after femtosecond laser treatment. Results showed that the induced periodic nanostructures enhanced the corrosion resistance of the titanium in a 3.5% NaCl solution through mechanisms such as the low proportion of high-angle grain boundaries, formation of a passive film with higher TiO2 fraction, and the air cushion effect on the structured surface, which reduced the corrosion rate.

Summary: The study revealed that muscovite exhibits a polymer-like response when irradiated with a laser pulse at 515 nm wavelength, forming cavitation and bubbling similar to previous observations in polymethyl-methacrylate (PMMA). Additionally, an absorption band edge for muscovite was reported at around 4 eV, lower than the previously reported band gap energy of 7.8 eV.

Summary: Structural color arises from the interference between light and periodic structures with characteristic length scales similar to the wavelength of visible light. The presence of long-range order usually leads to iridescence, while increasing disorder results in angle-independent colors. Random disorder scatters light across all wavelengths, resulting in white color. Sternotomini longhorn beetles exhibit various non-iridescent, vibrant color patterns. Through advanced imaging techniques and simulations, it is discovered that the color in Sternotomis virescens originates from amorphous photonic networks based on sub-units resembling the I-WP unit cell. This study provides insights into the formation of stable colors in longhorn beetles, highlights the advantages of imaging techniques, and raises questions about the mechanisms of amorphous structures in living organisms.

Summary: One-dimensional periodic surface structures were fabricated on amorphous hydrogenated silicon films by femtosecond laser irradiation. The orientation of the surface structure is determined by laser polarization and the concentration of excited carriers, affecting the formation of periodic relief. Femtosecond laser irradiation significantly increases the conductivity of the films by inducing the formation of Si nanocrystalline phase.

Summary: This study fabricated a surface-enhanced Raman scattering (SERS) substrate with ultrahigh sensitivity and stability using a simple and robust method. The substrate, composed of densely packed and uniformly distributed gold nanoparticles (Au NPs), exhibited a strong SERS effect. It achieved an ultra-low limit of detection for 4-AMTP molecules and demonstrated high sensitivity and reliability for detecting other molecules as well. Finite difference time domain simulations confirmed the experimental observations. The gold plasmonic nanostructures also showed good shelf stability, indicating potential for practical applications.

Summary: Direct ablation-free irradiation of Si-supported thin Au film by nanojoule-energy femtosecond laser pulses is demonstrated as a scalable technology for realizing plasmonic metasurfaces supporting collective resonances. By controlling the aperture size, the fabricated nanostructures exhibit high-Q collective plasmonic response within an expanded spectral range. Vacuum deposition of thin films enables fine tuning of the resonance position and expands the choice of available materials.

Summary: Femtosecond laser-modified amorphous silicon films demonstrated the formation of one-dimensional femtosecond laser-induced periodic surface structures, resulting in conductivity anisotropy. The nonuniform nanocrystallization of the irradiated films, depolarizing effect of LIPSS, and anisotropic crystalline phase distribution within the film contributed to the emergence of conductivity anisotropy. The nonlinearity observed in current-voltage characteristics of modified p-a-Si samples may be associated with the presence of both crystalline and amorphous phases.

Summary: The study found that exposing polypropylene fibers to argon plasma can create a crosslinked surface that reduces crazing formation. The results showed that Ar plasma treated PP fibers were able to reduce crazing and minimize fiber oxidation when exposed to dynamic distention and oxidative stress.

Summary: This study prepared undoped and Co doped ZnO nanostructures using a chemical co-precipitation method. It was found that Co doping caused a drastic change in the morphology of the nanoparticles from spherical to rod-like shapes, and a direct correlation was observed between the change in surface morphology and photoluminescence emission.
