1.1The questions this part answers

Key questions

  • Where is materials risk concentrated?
  • Which couplings carry materials shocks into other systems?
  • Which materials capabilities hold under compound stress?
  • What must 2027 evidence measure first?

In this part

  • Narrative
  • Headline finding
  • Lead figure
  • Five footprint and governance chapters
  • Twelve-domain reading
  • Sector screens
  • Dependency matrix
  • Risk objects
  • Capability ladder
  • Scenario
  • Three lenses
  • Portfolio

1.2The argument

Advanced materials are usually discussed as a race to find new compounds. The 2026 evidence reads them as three things at once: a discovery system whose claims need verification, a supply chain that rests on a few processing countries, and a family of engineered particles whose hazard evidence trails their use51720.

The discovery evidence is large and contested. A study reports 2.2 million predicted structures and 736 independent syntheses5. An autonomous laboratory reports 41 of 58 targets6. Two critiques find that these results do not show new, credible and useful materials89. A 2025 generative model adds one synthesised example7.

The supply evidence is the firmest part. China produced an estimated 82% of natural graphite and 99% of primary low-purity gallium in 2025, and export controls moved three times in a year17. The EU set 2030 benchmarks for extraction, processing and recycling18.

The safety and footprint evidence is the thinnest. IARC assessed carbon nanotubes in 201720, the Commission revised its safe and sustainable by design framework in 202619, and the energy and water use of production is not bound on a common basis. Superconductivity claims show how fast a headline can fall141516.

Figure 1.1How many of its 58 targets did the autonomous laboratory report realising? Compounds

The laboratory reported 41 realised compounds from 58 targets. A 2024 critique examined the products and finds that about two thirds of the claimed successes are likely known disordered phases of the predicted compounds. The two readings are not reconciled in the sources read69.

1.3Twenty couplings between five systems

The materials-centred matrix types the twenty couplings between the five core systems, read for their materials content. Strengths are Nexus estimates (ESTIMATED) from the cited evidence and analogue events; they set the graph that 2027 evidence will test.

Figure 1.2Couplings between the five systems

Each line is one coupling from one system to another, drawn by the strength the edition assigns. Strengths are Nexus estimates from the cited evidence and analogue events.
