• Continuous hydrothermal flow synthesis enables rapid formation of high-crystallinity VO 2 nanoparticles within seconds. • Reaction temperature and residence time play key roles in controlling particle size and crystallinity. • The thermochromic performance of composite films is governed by nanoparticle microstructure. • The developed flow-based approach offers a scalable route toward thermochro…

• Flame propagation of iron–methane–air mixtures was investigated experimentally. • Flame speed decreased near stoichiometric methane due to iron particle heat loss. • Under lean methane, iron oxidation supplied extra heat and enhanced propagation. • XRD showed Fe 2 O 3 formation under lean and FeO/Fe 3 O 4 under stoichiometric condition of methane-air. • Results clarify gas–solid interactions go…

Accurate and SI-traceable characterization of particle diameter and mass is essential for improving the reliability of aerosol measurements and powder technologies. In this study, monodisperse spherical polystyrene latex (PSL) particles were developed as the Certified Reference Material of National Metrology Institute of Japan, NMIJ CRM 5722-a. Both the particle diameter and mass were determined …
