Characterization of self-cleaning properties on superhydrophobic aluminum surfaces fabricated by direct laser writing and direct laser interference patterning
(Elsevier B.V., 2020-09)
Self-cleaning ability on technical surfaces can increase the added value of a product. A common path to achieve this property is making the surface superhydrophobic so that water droplets can roll down, picking up dirt ...
Comparison of structural colors achieved by laser-induced periodic surface structures and direct laser interference patterning
(Japan Laser Processing Soc, 2020-09)
Engraving surfaces with holographic features is not only used for decorative applications, but also for protecting products from counterfeit and piracy. Tins structural coloration can be produced on large areas at ...
Multi-scale surface patterning to tune friction under mixed lubricated conditions
(Springer Nature, 2019)
It is well accepted that the tribological performance of surfaces can be directly correlated with their energy efficiency and lifetime. Consequently, surface patterning has gained great attention to manipulate friction and ...
Effect of single- and multi-scale surface patterns on the frictional performance of journal bearings - A numerical study
(Elsevier, 2020)
The present study aims at numerically predicting the frictional performance of journal bearings with single- and multi-scale surface patterns considering the real 3D surface topographies after wearing-in in mixed-elastoh ...
Picosecond laser interference patterning of periodical micro architectures on metallic molds for hot embossing
(Multidisciplinary Digital Publishing Institute, 2019-10-18)
In this work, it is demonstrated that direct laser interference patterning (DLIP) is a method capable of producing microtextured metallic molds for hot embossing processes. Three different metals (Cr, Ni, and Cu), relevant ...
How to Tailor Structural Colors for Extended Visibility and White Light Generation Employing Direct Laser Interference Patterning
(Wiley VCH Verlag, 2019-07)
The appearance of a surface can be controlled by creating periodic microstructures designed to diffract light and produce structural colors. Nevertheless, since structural coloration is based on diffraction, the produced ...
Potential of Photocurrent Improvement in μc-Si:H Solar Cells with TCO Substrates Structured by Direct Laser Interference Patterning
(Wiley VCH Verlag, 2016-09)
Thin film solar cells based on weak absorbers like hydrogenated microcrystalline silicon (µc–Si:H) need an effective light management to maximize light absorption. In this work, the authors study numerically the light ...
Electron emission perpendicular to the polarization direction in laser-assisted XUV atomic ionization
(American Physical Society, 2017-08)
We present a theoretical study of ionization of the hydrogen atom due to an XUV pulse in the presence of an infrared (IR) laser with both fields linearly polarized in the same direction. In particular, we study the energy ...
Wettability control of polymeric microstructures replicated from laser-patterned stamps
(Nature Research, 2020-12)
In this study, two-step approaches to fabricate periodic microstructures on polyethylene terephthalate (PET) and poly(methyl methacrylate) (PMMA) substrates are presented to control the wettability of polymeric surfaces. ...
Development of a monitoring strategy for laser-textured metallic surfaces using a diffractive approach
(Multidisciplinary Digital Publishing Institute, 2019-12)
This paper addresses trajectory tracking problem in mobile robots considering additive uncertainties. The controller design method is based on linear algebra theory. Numerical estimation techniques are used to estimate the ...
