Overview

ORION (Optimized Research & Innovation for Organized Nanomaterials) is an autonomous AI agent platform that revolutionizes materials science research by integrating cutting-edge literature mining, intelligent candidate generation, automated simulations, and experimental design.

AI-Driven Discovery

Leverages state-of-the-art LLMs and graph neural networks to propose novel material candidates based on desired properties.

Knowledge Integration

Automatically ingests and processes scientific literature, patents, and experimental data into a comprehensive knowledge graph.

Automated Workflows

Generates detailed laboratory protocols and interfaces with simulation tools for in-silico validation.

Architecture

Component Overview

Microservices Architecture

ORION uses a microservices architecture for scalability and maintainability. Each component runs independently and communicates via REST APIs and message queues.

Core Components:

Data Ingestion Service: Processes literature, patents, and experimental data
Knowledge Graph Engine: Neo4j-based graph database with custom ontology
RAG Service: Hybrid retrieval with cross-encoder reranking
LLM Engine: Fine-tuned models for materials science
Candidate Generator: Ensemble models with uncertainty quantification
Simulation Orchestrator: Interfaces with DFT/MD tools
Protocol Generator: Template-based synthesis protocol creation

Knowledge Graph

The knowledge graph is the central repository for all materials science knowledge in ORION. It uses Neo4j to store and query complex relationships between materials, properties, methods, and applications.

Schema Design

Node Types

Material: Chemical compounds with composition and structure
Property: Physical, chemical, and electronic properties
Method: Synthesis and characterization techniques
Application: Use cases and device applications
Publication: Scientific papers and patents

Query Examples

# Find materials with specific bandgap
MATCH (m:Material)-[:HAS_PROPERTY]->(p:Property)
WHERE p.name = 'bandgap' AND p.value >= 1.5 AND p.value <= 2.0
RETURN m.formula, p.value
ORDER BY p.value

# Find synthesis methods for a material
MATCH (m:Material {formula: 'TiO2'})-[:SYNTHESIZED_BY]->(method:Method)
RETURN method.name, method.parameters
