Controlling the TiN Electrode Work Function at the Atomistic Level: A First Principles Investigation

IEEE Access, 2020
The paper reports on a theoretical description of work function of TiN, which is one of the most used materials for the realization of electrodes and gates in CMOS devices. Indeed, although the work function is a fundamental quantity in quantum mechanics

Hydrodynamic Voltammetry with Channel Electrodes: Microdisk Electrodes

The Journal of Physical Chemistry, 1995
Both the strongly implicit procedure and the alternating direction implicit finite difference (ADI) technique are used to simulate mass transport to a microdisc electrode located in a channel flow, taking account of diffusion in three dimensions and the parabolic laminar convective flow over the electrode surface.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Determination of the effective thickness of a porous electrode in a flow-through reactor; effect of the specific surface area of stainless steel fibres, used as a porous cathode during the deposition of Ag(I) ions. [PDF]

, 2008
This study discusses the use of potential distribution analysis during the deposition of metal ions, at limiting current conditions and determines the optimum electrode thickness at which no hydrogen evolution occurs.

Chronoamperometry at Channel Electrodes: Theory of Double Electrodes

The Journal of Physical Chemistry, 1994
A theoretical treatment is presented which permits the computation of transient effects at double-channel electrodes. In particular, the current response of a downstream «detector» electrode to a potential step at an upstream «generator» electrode is established, and it is shown that such experiments can provide unique information both about the ...

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.
