Effect of Microstructure and Space Charge on Cathodic Polarization

ECS Proceedings Volumes, 2005
Bar-shaped samples of porous samaria-doped ceria (SDC) with large neck sizes were fabricated using a three-step method. In the first step, two phase samples containing NiO + SDC were fabricated by sintering powder compacts. In the second step, NiO was reduced to Ni at 800°C in a hydrogen-containing atmosphere.

Hydrogen charging in nickel and iron and its effect on their magnetic properties

, 1996
The current study was undertaken to explore the possibility of detecting hydrogen cavitation in magnetic materials through magnetic propertymeasurements. It is known that dissolved hydrogen in a material causes microvoids.

Engineered AuNPs/fMWCNT Nanocomposite Electrodes for High‐Sensitivity Methylglyoxal Sensing in Saliva and Sweat for Non‐Invasive Diabetes Monitoring

Advanced Healthcare Materials, EarlyView.
An AuNPs/fMWCNT nanocomposite‐modified screen‐printed carbon electrode was engineered via sequential electrodeposition and integrated into a 3D‐printed microfluidic platform for ultrasensitive methylglyoxal detection. The non‐invasive sensing platform enables rapid analysis in saliva and sweat, highlighting strong potential for wearable point‐of‐care ...

Crystal Growth Engineering for Dendrite‐Free Zinc Metal Plating

Advanced Materials, EarlyView.
This research employed the rare‐earth ion dysprosium (Dy) to modulate aqueous zinc (Zn) metal plating. Integrated multiscale experiments and computational modeling unveiled the preferential adsorption of Dy on specific crystal facets, which activated screw dislocation‐driven Zn growth.

Ionic fluxes of charged particles at cathode region

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We analyze the disperse particles charging at cathode region by collisional and diffusive mechanisms. The dependence of charge quantity at nanoparticles on their sizes and characteristics of motion in the electrical field is defined. It is shown that there is the velocity distribution of directed motion of charged particles to the cathode surface at ...

Internal and surface damage after electrochemical hydrogen charging for ultra low carbon steel with various degrees of recrystallization

, 2016
An ultra low carbon (ULC) steel was subjected to electrochemical hydrogen charging to provoke hydrogen induced damage in the material. The damage characteristics were analyzed for recrystallized, partially recrystallized, and cold deformed material.

High Light Utilization and Color Rendering in Vacuum‐Deposited Semitransparent Perovskite Solar Cells

Advanced Materials, EarlyView.
In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

POM‐Based Water Splitting Catalyst Under Acid Conditions Driven by Its Assembly on Carbon Nanotubes

Advanced Materials, EarlyView.
A newly‐engineered POM‐based electrocatalyst incorporating non‐innocent counter cations exhibits fast kinetics for either the OER or HER under strongly acidic conditions (1 m H2SO4), depending on whether it is assembled on carbon nanotubes (1@CNT) or physically mixed with them (1/CNT). In water‐splitting tests using a two‐electrode setup, these systems

Effect of cathodic hydrogen charging on the wear behavior of 5754 Al alloy

, 2017
This research work is focused on investigating the effect of hydrogen uptake on the structural and tribological properties of 5754 Al alloy. The aim is to understand the synergism between hydrogen uptake and wear. In particular, hydrogen was incorporated
