SOOT PARTICLE SIZE DISTRIBUTION NEAR THE CYLINDER WALL IN A DIRECT INJECTION DIESEL ENGINE [PDF]
Investigation of soot particle size and its distribution inside a direct injection diesel engine provides the idea of how soot particles are distributed in an engine cylinder, particularly near the cylinder wall.

Abstract Substantial concentrations of graphitic carbon and its associated large optical absorption coefficient are observed in the Arctic. The graphitic content shows a dramatic increase from late fall to early spring, reaching levels that are comparable to those found in urban environments (i.e., the peak values in February are only about a factor ...

Particle formation in oxymethylene ethers (OMEn, n = 2-4) / ethylene premixed flames [PDF]
Alternative synthetic fuels can be produced by renewable energy sources and represent a potential route for solving long-term energy storage. Among them, oxygenated fuels have the advantage of significantly reducing pollutant emissions and can therefore be used as carbon-neutral substitute fuels for transportation.

This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
