Research method
SECCM
3 studies
Scanning electrochemical cell microscopy (SECCM) maps electrochemistry with a droplet cell, so activity can be read grain-by-grain or particle-by-particle.
It turns a 'the electrode is active' claim into a spatial map undergraduates can reason about.

What we know
- This library holds 3 empirical chemistry papers on seccm with isolated findings, rates or spectra rather than reviews.
- Thousands of nanoscale voltammograms show every ITO patch oxidizes ferrocenedimethanol; only 0.2% is fully reversible, and the old sparse-site model fails.
- A little polyvinylpyrrolidone stops alkaline SECCM droplets from spreading, enabling single-grain OER maps that rank Pt(110)/(111) above (100) at pH 13.8.
- SECCM impact transients show 10 nm Ag particles often dissolve in one spike, but larger ones leave, return, and only partly oxidize.
Largest unresolved question
Droplet wetting and electrolyte composition change which sites you actually interrogate.
Common misconceptions
SECCM images the whole electrode the same way AFM does.
It is a local electrochemical measurement, not a topographic image of every atom.

What the evidence shows
Drawn from 3 studies in this library. Mix labels say which citation roles are present; they are not a strength score. Supports means evidence for a finding; Challenges means evidence against a stated position; Qualifies marks scope.

PaperFren reads this as a limit on how far one study travels — different assays, populations, or outcomes — not a forced fight between papers.
