Chem is try — the art of transforming matter.
Data is Do, Analyze, Think, Act — the art of transforming meaning.

Research

I'm mostly focused on the electrochemistry memristor development, the interdisciplinary project involves:

  • Electrochemistry memristor construction and analysis
  • Neural networks, machine learning developments
  • Molecular dynamics analysis
  • DFT, COMSOL simulation

Kirchhoff’s law for memristors

Extends Kirchhoff’s laws to include memristive elements, capturing the dynamic relationship between voltage, current, and memory-dependent resistance in circuit analysis.

Construct neural network

Designs a neural network model to emulate memristor behavior, capturing its nonlinear current–voltage dynamics and memory-dependent resistance for circuit prediction and optimization.

MD simulation and nanopipette simulation

Simulates ionic transport and electrochemical behavior in nanopipettes to study nanoscale sensing, flow, and conductance mechanisms.

Toolkit

Tool 1 — Gamry DTA → Excel (Online)

Convert common Gamry .DTA electrochemistry files (CV/CA/CP/EIS, etc.) into an Excel workbook directly in your browser. Your file is processed locally on your device (no upload).

Download desktop version (.zip)

Choose a file to enable conversion.

What will the Excel contain?
  • Sheet per curve: Curve 1, Curve 2, … (each ... TABLE block (e.g., ZCURVE TABLE, CURVE1 TABLE))
  • Columns: exported as-is from the DTA table
  • Optional: a Header sheet with key/value metadata parsed from the file

Tool 2 — Equation + Data Visualizer (Online)

Plot custom equations and overlay them with experimental datasets from Excel/CSV. To keep this page uncluttered, the visualizer opens in a separate tab/window. Everything runs locally in your browser (no uploads).

  • Equations: exp/sin/cos/tan/log/sqrt/abs, powers (^), constants (pi, e)
  • Data: upload one or more Excel/CSV files (two columns: x,y) for comparison
  • Overlays: assign curves/datasets into up to 10 figures
Open Tool 2 (new window) Open in this tab

If a pop-up blocker interferes, use “Open in this tab”.

Tool 3 — Time-Series Plotter & Trajectory GIF (Online)

Upload an Excel or CSV file in the browser, choose your columns, and make one of two plot types: a lag plot using variable(n) versus variable(n+skip), or a variable trajectory plot in 2D/3D.

  • Upload first: choose a sheet, then select the time/variable columns
  • Plot type A: plot variable(n) versus variable(n+skip) as a lag plot
  • Plot type B: plot variable trajectories in 2D or 3D and export a moving-point GIF
Open Tool 3 (online) Download example Excel (.xlsx)

Everything runs locally in the browser. No server upload is required.
