Femtosecond laser-based Nonlinear Laser Lithography (NLL) was applied to AISI 316L stainless steel, which requires surface modification to achieve satisfactory tribological behaviour. NLL advances over the well-known Laser Induced Periodic Surface Structures (LIPSS) in terms of uniformity and long-range order of high speeds, over large areas. A galvanometric scanner head was used for an high production rate. Dry and lubricated sliding tests, considering different orientations of the nanotexture showed that COF values after NLL treatment are significantly lower. In lubricated tests, COF values of NLL-treated surfaces are nearly half the values of untreated surfaces, whereas the difference further increases when measured in dry conditions, where the orientation of the surface texturing influences the results.

Metal-assisted nano-textured solar cells with SiO2/Si3N4 passivation Es, Fırat; Baytemir, Gulsen; Kulakci, Mustafa; Turan, Raşit (2017-02-01) We demonstrate the fabrication of nano-sized surface textured crystalline silicon by a metal-assisted electroless etching method with nitric acid added as the hole injection agent. This method generates randomly shaped cone-like structures that offer a clear advantage over nanowires by enabling straightforward passivation with standard techniques. Average reflection values as low as 3% have been achieved. Optimizing the thickness of anti-reflective coatings, the doping depth and the screen-printed metal fir...
Application of pulsed laser deposition and laser-induced ion implantation for formation of semiconductor nano-crystallites WOLOWSKI, JERY; BADZIAK, JAN; CZARNECKA, ANNA; PARYS, PİETR; PISAREK, MARCİN; ROSINSKI, MARCİN; Turan, Raşit; Yerci, Selçuk (2007-03-01) This work describes the application of laser ion source (LIS) for fabrication of semiconductor nanostructures, as well as relevant equipment completed and tested in the IPPLM for the EU STREP "SEMINANO" project and the obtained experimental results. A repetitive Pulse laser system of parameters: energy of similar to 0.8 J in a 3.5 ns-pulse, wavelength of 1.06 mu m, repetition rate of up to 10 Hz and intensity on the target of up to 10(11) W/cm(2), has been employed to produce Ge ions intended for ion implan...
Epoxy-based composites and coatings: improvement of multifunctional properties Çaldıklıoğlu, Almira; Bayram, Göknur; Department of Chemical Engineering (2019) The purposes of this study are to improve mechanical properties, thermal stability, resistance to flammability, electrical conductivity and hydrophobicity of epoxy (E) by incorporation of expanded graphite (EG) and titanium dioxide (T) particles. In this study, sonication with the use of solvent method was primarily determined for the epoxy-based binary composite and coating preparation. By this method, the epoxy composites and coatings were produced by changing EG concentration as 0.05, 0.1, 0.25, 0.5, 0.7...
Surfactant-modified multiscale composites for improved tensile fatigue and impact damage sensing Yesil, Sertan; Winkelrnann, Charles; Bayram, Göknur; La Saponara, Valeria (Elsevier BV, 2010-10-25) This paper documents the mechanical and electrical performance of self-sensing conductive polymer composites prepared with a low-cost technique and small hardware, able to considerably improve the dispersion and the surface adhesion of multi-walled carbon nanotubes (CNTs) in epoxy resin with respect to amine-modified CNTs and as-received CNTs. Surface treatment of the CNTs is performed using hexamethylene diamine, or a mix of sulfuric and nitric acid, and one of two surfactants (for the diamine treatment on...
Optomechanical analysis and experimental validation of bonding based prism and mirror mounts in a laser system Ünal, Uğur; Balkan, Raif Tuna; Department of Mechanical Engineering (2012) In this thesis, different optomechanical design and adhesive configurations for mounting mirrors and prisms used in a laser system are investigated. Maintaining stability and strength of optical components of a laser device is difficult especially if the system is to be used in military environment. In order to determine the strength of prism mounts to high acceleration levels, mathematical correlations derived by Yoder are used. By use of these mathematical correlations, safety factor of different prism mo...
