EQCM Analysis of Titanium Corrosion in Peroxide- or Fluoride-Containing Solutions

The Bulletin of Tokyo Dental College, 2013
Although offering superior resistance to corrosion, titanium is unable to withstand discoloration with exposure to peroxide or fluoride. The mechanism of this discoloration, however, remains to be clarified. The purpose of this study was to investigate the mechanism underlying discoloration of titanium with immersion in peroxide- or fluoride-containing

Revisiting Electrolyte Effects in Oxygen Evolution Reaction on NiOOH: pH‐Controlled Activity Depends on Catalyst Mesostructure

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
pH and electrolyte composition significantly affect the oxygen evolution activity of NiOOH, with the extent of the pH effect depending on layer morphology. Porous, heterogeneous layers show a strong pH dependence, while thin, dense layers exhibit only a weak effect, resulting in distinct pH‐activity trends.

Role of Binders on the Performance of SnO2‐Based Gas Diffusion Electrodes for Electrochemical CO2 Reduction to Formic Acid

ChemElectroChem, Volume 13, Issue 18, 19 September 2026.
Highlights Ionomers (PIL1‐d, Nafion, Sustainion XA9 & PTFE) have a significant effect on the performance of SnO2‐based gas diffusion electrodes (GDE) for eCO2RR. PIL1‐d effectively stabilizes SnO2 catalyst nanoparticles in spray‐coating inks and enhances eCO2RR towards formic acid.

Selenophene π‐Bridge Enables Balanced Ambipolar Transport in High‐Performance Organic Electrochemical Transistors

Advanced Science, Volume 13, Issue 49, 3 September 2026.
We synthesized a high‐performance balanced ambipolar OECT polymer, P(gTDPPSe), via selenophene π‐bridge engineering. The selenophene π‐bridge enhances backbone planarity and optimizes the energy levels for doping, enabling high and balanced p/n‐type transconductance‐a key factor for high‐gain complementary inverters.
