In this work, we evaluated the ability of three numerical methods to predict phase formation in Cu–Zn binary and Cu–Ti–Zn ternary alloy thin films deposited by DC-magnetron sputter deposition. Molecular dynamics (MD) simulations were carried out simulate growth film study organization at atomic level. A Machine Learning (ML) approach trained with a recently published bulk HEA (high-entropy alloy) database was used determine presence an amorphous phase, solid solutions, or/and intermetallics....
Previous studies have shown that undoped and doped SnO2 thin films better optical electrical properties. This study aims to investigate the thermoelectric properties of two distinct semiconducting oxide films, namely F-doped (FTO), by nebulizer spray pyrolysis technique. An X-ray diffraction reveals synthesized exhibit a tetragonal structure with (200) preferred orientation. The film structural quality increases from FTO due substitution F- ions into host lattice. thickness 530 nm for 650...
In this work, we present an new approach for creating laser-induced periodic surface structures (LIPSS) on a soda-lime glass using femtosecond (fs) laser source, marking the first instance of such process. The formation LIPSS upon irradiation with linearly polarized fs-laser pulses (τ = 300 fs, λ 1030 nm) in air environment is experimentally studied. Due to nonlinear absorption behavior beam glass, conducted three different investigations irradiate substrate: (i) thin film-mediated under top...
Single-step thermal chemical vapor deposition was optimized at 400 °C for the growth of CoFe2O4 spinel thin films starting from corresponding metal acetylacetonate precursors. Enhanced magnetization observed conditions leading to a columnar with preferred (100) orientation. The implemented liquid precursor delivery secured reliable films' composition control and straightforward dosage acetylacetone, as molecular inhibitor, enhance film conformality on structured surfaces. enabled an...

This investigation focuses on the influence of thin films laser-induced periodic surface structures (TF-LIPSSs) formed soda-lime glass using femtosecond laser pulses with a wavelength 515 nm. In this study, we introduce new framework involving combined metal film chromium and silver (Cr:30 nm + Ag:100 nm) deposited onto by DC magnetron sputtering. Due to their better coupling heat accumulation, enables more efficient transfer energy dielectric substrate, leading formation structures. The...
In this study, we examine texturing features on soda-lime (SDL) silicate glass bottles achieved using a Carbon Dioxide (CO2) laser with continuous wave power (25 W at 10.6 µm).SDL samples were subjected to irradiation in both static and dynamic modes.In the mode, exposure time (τON) varied from 10 µs 2 ms, while mode involved scan velocities (line) ranging 20 mm/s 3 m/s.Our evaluation focused engraving rate, fracture morphologies, damaged zone characteristics.Using optical microscopy stylus...
