Shear-Exfoliated Few-Layer Graphene (FLG) via High-Speed Hydrodynamics

Rejected

This concept did not clear the framework. The reasoning is published in full below.

Why it failed

• Voided by: Illegitimate incumbent

Assessment

Voided under Sub-test A and B because the named comparator (Boron Nitride) is an unformulated raw ceramic filler input rather than a finished TIM product specified by end buyers. Additionally, price parity ($80/kg) is explicitly acknowledged in the text as unsourced due to an absence of BN pricing literature.

Claimed advantage

30.0 W/mK composite thermal conductivity vs 5.0 W/mK for Boron Nitride composite (6.0x delta)

Named comparator: Boron Nitride (BN)

Also flagged

• Evidence rests on non-peer-reviewed sources
• Price parity asserted, not sourced
• no_production_runsheet
• unsourced_equipment
• no_opex

A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
