LIPSS-Sticks: Laser induced double self organization enhances the broadband light harvesting of TiO2 nanotube arrays

, 2020
Sub-wavelength laser induced periodic surface structures (LIPSS-Sticks) created by ultrashort pulsed laser irradiation on the surface of titanium are used for the first time to template the electrochemical growth of titanium dioxide nanotube arrays. This

Contribution of defect on early stage of LIPSS formation

Optics Express, 2014
We investigated an early stage of laser-induced periodic surface structure (LIPSS) formation to elucidate the contribution of defects on the formation. 4H-SiC crystals were irradiated by multiple pulses of femtosecond laser with different laser spot sizes.

Numerical FDTD-based simulations and Raman experiments of femtosecond LIPSS

Optics Express, 2021
The article describes the results of finite-difference time-domain (FDTD) mathematical modeling of electric field strength distribution near the gold laser-induced periodic surface structures (LIPSS). Both theoretical and experimental results have been described for two fabricated morphologies: round «hill-like» and grating structures.

Wettability surface control on stainless steel by LIPSS formation

Journal of Physics: Conference Series, 2021
Abstract In this paper, laser-induced periodic structures are obtained on the surface of SS304 stainless steel when treated with femtosecond laser radiation. The dependence of the period of surface structures on the speed and power of laser radiation treatment is revealed.

Phase-inversion constructed Mo₂C@NC microreactor with optimized pyridinic N p-band center for high-performance Li-S batteries. [PDF]

Smart Mol
A phase‐inversion constructed Mo2C@NC microreactor activates the intrinsic catalysis of nitrogen‐doped carbon via interfacial electron redistribution. Strong charge transfer to pyridinic N optimizes the p‐band center, enabling efficient lithium polysulfide adsorption, fast redox kinetics, and long‐term stable, high‐rate Li–S battery performance ...
