Effect of non-stationary current regimes on the morphology of silver electrodeposits [PDF]
Journal of the Serbian Chemical Society, 2009 This work is concerned with the use of reverse current regimes in order to form small-grained and compact silver deposits during the electrorefining process. Several parameters were varied, i.e., i) anodic overpotential, ii) cathodic vs.

Improvement of inverse characteristics of silicon varicap by using low-temperature gettering
Технологія та конструювання в електронній апаратурі, 2023 Varicaps are widely used in radio electronics as a variable capacitance, the value of which is controlled by voltage. However, it should be noted that the cost of varicaps remains relatively high due to a low yield of suitable devices.

Nonsinusoidal current and current reversals in a gating ratchet [PDF]
Physical Review E, 2015 In this work, the ratchet dynamics of Brownian particles driven by an external sinusoidal (harmonic) force is investigated. The gating ratchet effect is observed when another harmonic is used to modulate the spatially symmetric potential in which the particles move.

Improving parameters of planar pulse diode using gettering
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2021 Pulse diodes are widely used as part of high-frequency pulse circuits. However, it should be noted that the cost of pulsed diodes remains relatively high, due to the low yield of suitable devices when they are sorted according to the criteria of reverse ...

Electrochemical deposition and characterization of zinc–nickel alloys deposited by direct and reverse current [PDF]
Journal of the Serbian Chemical Society, 2005 Zn–Ni alloys electrochemically deposited on steel under various deposition conditions were investigated. The alloys were deposited on a rotating disc electrode and on a steel panel from chloride solutions by direct and reverse current.
