The N.A.C.A. Combustion Chamber Gas-sampling Valve and Some Preliminary Test Results [PDF]
A gas sampling valve of the inertia-operated type was designed for procuring samples of the gases in the combustion chamber of internal combustion engines at identical points in successive cycles so that the analysis of the gas samples thus procured may ...

Gas‐ and Liquid‐Phase Catalysts for Solar‐Driven Catalytic Ammonia Decomposition
Advanced Sustainable Systems, EarlyView.Amid the drive toward carbon‐neutral hydrogen, this review analyzes photocatalytic ammonia decomposition in gas‐ and liquid‐phase systems. It examines catalyst families—TiO2, ZnO, Ru, single‐atom, and antenna–reactor designs. This study summarizes advances in bandgap tuning, active‐site and cocatalyst engineering, photothermal coupling, and machine ...

Ni Single Atoms in Zeolite Beta for Selective Alkyne Hydrogenation
Advanced Sustainable Systems, EarlyView.Single‐atom Ni in zeolite Beta (Ni1/BEA) selectively remove trace acetylene from ethylene. Ni1/BEA achieve full conversion with ≈89% ethylene selectivity, stable for 24 h without coking, and 12 times higher TOF than prior zeolite‐supported single‐atom Ni catalysts. Na+ exchange suppress Brønsted acid‐catalyzed oligomerization. Under ethylene‐rich feeds,
