ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.A hierarchical FeOOH–FeP@Ni3S2 electrocatalyst is engineered on 3D Ni foam to enable efficient alkaline oxygen evolution. Operando spectroscopic techniques reveal dynamic surface reconstruction and proton‐coupled electron transfer (PCET) kinetics. The catalyst exhibits low overpotential and industrial‐level current operation, driving high‐performance ...

Tetramethylammonium hydroxide (TMAH) treatment of dry-etched trenches on (010) β-Ga2O3 to enhance trench profiles [PDF]
AIP AdvancesWe demonstrated heated tetramethylammonium hydroxide (TMAH) etching (25 wt. % concentration, at 90 °C) as an effective post-dry-etch treatment for improving dry-etched trench profiles on (010) β-Ga2O3. This treatment successfully converted rough, tapered

Determination of precise crystallographic directions for mask alignment in wet bulk micromachining for MEMS [PDF]
, 2016 In wet bulk micromachining, the etching characteristics are orientation dependent. As a result, prolonged etching of mask openings of any geometric shape on both Si{100} and Si{110} wafers results in a structure defined by the slowest etching planes.

Titanium Carbide MXene Synthesis by Etching of Titanium Aluminum Carbide in Acetic Acid Solution
Small, Volume 22, Issue 26, 8 May 2026.We propose a new method for Ti3C2Fz MXene synthesis using acetic acid as an etching environment. Contrary to the most often used HF/HCl, a weak acid solution is more beneficial for mass production with reduced environmental impact. Optimal balance between the acetic acid and water amounts allows for complete etching of Al atoms yielding partially ...
