The Chemistry of Soot: Carbon Deposits Under Extreme Heat

A molecular-level examination of how incomplete combustion generates polycyclic aromatic hydrocarbons and soot particles — and why understanding the HACA mechanism, nucleation kinetics, and aggregate morphology matters for engineers, health researchers, and environmental scientists in the Netherlands and beyond.

Carbon Black vs. Soot: Molecular Distinctions That Transformed Industrial Chemistry

Carbon black and soot are both largely elemental carbon — yet one reinforces billions of tyres while the other is a hazardous air pollutant regulated under EU Directive 2004/107/EC. This analysis dissects the chemical, structural, and production differences that determine which material ends up in your car tyres and which ends up in environmental monitoring reports.

Topics covered: furnace-process production, particle morphology, BET surface area, PAH content, ISO 18852 classification, carbon black market applications, soot health impact studies by RIVM.

From Roman Hypocausts to Smart Heat Pumps: 2,000 Years of European Heating Engineering

The longest article in our collection: a sweep through twenty centuries of European thermal engineering, from the Roman underfloor heating systems of Britannia and Gaul through the open hearths of medieval great halls, 16th-century chimney fireplace innovation, 17th-century tile stoves, 19th-century steam radiators, 20th-century condensing boilers, and the ongoing Netherlands energy transition from gas to heat pumps.
