CD Superconductor Framework

Computational framework for discovering room-temperature superconductors via correlation-driven (CD) mechanisms.

📊 Overview

This repository contains production planning tools for synthesizing candidate CD superconductor materials identified through computational screening.

🔬 Contents

update_production_details.py

Python script to augment the CD Superconductor screening Excel with detailed production process information:

• Production Methods - Arc melting, DAC synthesis, hydride formation
• Precursor Materials - High-purity elemental sources, isotopes
• Temperature Profiles - Annealing schedules, laser heating parameters
• Safety Compliance - OSHA, NRC, DOE regulations
• Cost Estimates - Equipment, materials, facility requirements
• Timelines - Realistic synthesis schedules

🛠️ Usage

# Install dependencies
pip install openpyxl

# Run the script (requires CD_Superconductor_Screen.xlsx in the same directory)
python update_production_details.py

Output: CD_Superconductor_Screen_with_Production.xlsx

📋 Supported Materials

Binary Pairs (Sheet 2)

• d-d Intermetallics - Arc melting + long anneal (2-4 weeks, $50-150k)

• Special Materials:
  • C-Sc (Scandium carbide) - $100-200k, 3-6 weeks
  • Mo-Tc (Technetium alloy) - $500k+, 12-18 months (NRC license required)
  • Nb-V (Niobium-vanadium) - $50-100k, 2-3 weeks

Ternary Hydrides (Sheet 3)

Automatic safety customization for:

• Beryllium - OSHA 29 CFR 1910.1024 compliance
• Thorium - NRC 10CFR40 source material license
• Rare Earths (La, Y) - Pyrophoric metal handling

⚠️ Safety Notes

This script incorporates regulatory compliance requirements:

• OSHA - Beryllium PEL (0.2 µg/m³), cadmium (5 µg/m³)
• NRC - Radioactive materials (Tc-99, Th)
• DOE - High-pressure equipment, Class 4 lasers

Always consult institutional EH&S before synthesis.
