This article is focused on the automated synthesis of slow-wave structures based on microstrip lines loaded with patch capacitors. Thanks to the presence of the shunt capacitors, the effective capacitance of the line is enhanced, and the phase veloci

In this study, we examined how aluminium corrosion in Al–Cu/PANI galvanic couples in a marine environment is influenced by deposition of polyaniline (PANI) on copper. Polarization curves and immersion assays in 0.1 M NaCl were performed. The morpho

In this study we examined the rhenium electrodeposition process onto p-Si(1 0 0). The study was carried out by means of cyclic voltammetry (CV) and the potential-steps method from which the corresponding nucleation and growth mechanism (NGM) were det
