Technical
The STREAM™ platform, explained
A vertically integrated graphene refinery that converts carbon-rich feedstocks into few-layer graphene and graphene oxide.
Two production pathways
Graphene, and graphene oxide
STREAM-G™ · Engineered for performance
Argo's proprietary production pathway for micron-scale, few-layer, low-defect graphene from carbon-rich feedstocks. It preserves high electrical and thermal conductivity, mechanical strength and large continuous sheets, while supporting consistent, scalable production.
STREAM-O™ · Engineered for integration
Graphene oxide produced from STREAM-G™ graphene through the STREAM-O™ oxidation process. Oxygen-containing functional groups let it interact and bond with surrounding materials, and disperse in water-based systems.

Analysis
Confirmed three ways
Raman spectroscopy
Confirms high-quality, low-defect few-layer graphene.
XPS
Confirms predominantly sp²-bonded carbon with minimal oxygen functionalization.
XRD
A dominant (002) peak confirms minimal crystalline impurities.
Feedstocks
Multiple carbon sources. Greater strategic flexibility.
