📖 About This Skill

SKILL.md — AFM Force Curve Analyzer

Tool Name

afm-force-curve-analyzer — AFM nanoindentation & force spectroscopy data analyzer

When to Use

When analyzing AFM force-distance curves, nanoindentation data, adhesion maps, or force spectroscopy measured during electrochemical cycling (LSV/CV/CP/CA). Triggers on phrases like:
  • "AFM force curve分析"
  • "force spectroscopy"
  • "nanoindentation"
  • "adhesion force"
  • "Young's modulus AFM"
  • "Sneddon模型"

    • Analysis Capabilities

  • Force-distance (F-D) curve import & preprocessing (baseline subtraction, tip radius correction)
  • Young's modulus extraction via Sneddon model (cone/pyramid/spherical indenters)
  • Adhesion force (F_ad) & pull-off work calculation
  • Multiple indentation models: Hertz, Sneddon (cone/pyramid), JKR, DMT
  • Electrochemical potential correlation: modulus/adhesion vs. applied potential
  • Deformation recovery analysis (creep/viscoelastic relaxation)
  • Force map 2D visualization (adhesion, modulus, deformation)
  • Multi-curve statistical comparison (fresh vs. cycled catalyst)
  • Built-in reference database: NiOOH/γ-NiOOH/FeOOH/IrO₂/RuO₂/TiO₂/LiCoO₂/Si/Pt/Au

    • Input Formats

  • CSV/XLSX ( Asylum MFP-3D / Bruker Nanoscope / JPK / NT-MDT / Keysight / Park )
  • TXT (force curve single file, force map grid CSV)
  • NWI (Nanonis)
  • SXM (NT-MDT)

    • Output

  • PNG multi-panel dashboard (F-D curves + statistics + potential correlation + 2D map)
  • CSV with all extracted parameters
  • JSON with metadata
  • Markdown summary report

    • Key Calculations

  • Sneddon model: E = (π/2) × F / (δ² × tan α) for conical indenter
  • Adhesion work: W_ad = ∫F_ad dδ
  • Reduced modulus: 1/E_r = (1−ν²)/E + (1−ν_tip²)/E_tip
  • Standard indenters: ν_sample=0.3 (NiOOH), ν_tip=0.17 (SiN), E_tip=97 GPa (SiN)

    • Usage

    afm-force-curve-analyzer --input data.csv --indenter conical --tip-radius 20e-9 \
  --poisson 0.3 --output ./results --format png,csv,json,md
