The Charge Distribution on the Cathode of a Straw Tube Chamber

, 2000
We use Green's reciprocation theorem and the method of weighting fields to deduce the charge distribution on the cathode of a straw tube proportional chamber. The time dependence of the associated current is also discussed.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

The effect of absorbed hydrogen on the dissolution of steel

Heliyon, 2016
Atomic hydrogen (H) was introduced into steel (AISI 1018 mild steel) by controlled cathodic pre-charging. The resultant steel sample, comprising about 1 ppmw diffusible H, and a reference uncharged sample, were studied using atomic emission ...

Mitigating Concentration Polarization in Dry‐Processed Ultra‐Thick Cathodes Using a Low‐Viscosity Electrolyte With Soft Li+ Solvation

Advanced Functional Materials, EarlyView.
A low‐viscosity, soft‐solvating methyl ethanoate (ME)‐based electrolyte facilitates electrolyte infiltration into dense dry‐processed ultra‐thick NCM622 cathodes while reducing Li+ desolvation barriers at Li‐metal anodes. Balanced cathode‐scale ion transport and anode‐side interfacial kinetics mitigate concentration polarization and interfacial ...

Effect of Electrochemical Potential and Solution Concentration on the SCC Behaviour of X-70 Pipeline Steel in NaHCO3

International Journal of Electrochemical Science, 2009
The stress corrosion cracking (SCC) behaviour of a X70 microalloyed pipeline steel, with different heat treatments under both anodic and cathodic overpotrentials has been evaluated by using of the slow strain rate testing (SSRT) technique at 50°C.

Ultrafast Thermal Shock Synthesis of CuNiSnLa Medium‐Entropy Metallic Glass for Sustainable Nitrogen Fixation via Plasma‐Coupled Electrocatalysis

Advanced Functional Materials, EarlyView.
This work introduces an ultrafast thermal shock strategy to synthesize a CuNiSnLa medium‐entropy metallic glass (MEMG). The rapid heating and cooling process generates a robust, highly active catalyst for electrocatalytic nitrate reduction to ammonia (NRA).

Polarization behavior of pipelines with peeled anti-corrosive coating under pulsed current cathodic protection

You-qi chuyun
Objective Buried oil and gas pipelines are typically safeguarded by both anti-corrosive coating and cathodic protection. However, over time, the anti-corrosive coating degrades and may peel off during extended operation.

Mechanisms of Degradation in Li‐Ion Batteries Under Low Temperature Exposures

Advanced Functional Materials, EarlyView.
Low‐temperature exposures, or freeze‐thaw cycles, are observed to significantly accelerate the degradation of Li‐ion batteries. A combination of electrolyte phase separation and mechanochemical stress leads to reversible and irreversible performance losses.
