The platinum substitution problem
Why iridium and platinum supply cannot support a 100 GW European electrolyser build-out — and why RuO₂-coated nickel mesh is the only realistic path.
SUPPLYClass-1 versus Class-2: the nickel misread
The financial press reports "nickel surplus" while precision applications face chronic shortage. The gap is a purity specification.
MARINEIMO Ballast Water Management — the 90,000-vessel retrofit
Convention entered into force 2017. Retrofit deadlines are converging on 2026–2028. Ninety thousand vessels. Nickel filtration mesh is the sharp end.
EMIShielding effectiveness and the fourth purity decimal
Why moving from 99.8% to 99.99% purity adds ~18 dB of shielding. A grain-boundary explanation.
SEMISub-3 nm: why deposition substrates now care about roughness
At 3 nm node and below, substrate roughness couples directly into defect density. Sub-nanometre Ra becomes a pre-condition for yield.
ECONWhy Singapore: jurisdictional logic for precision-metals commerce
ACRA governance, MAS supervision, Class-1 logistics, regional OEM density, English-common-law enforceability. A sober comparison.
Case studies
Sector-specific deployments with measured outcomes. Useful reading alongside the explainers.
