Over the last several decades, turbine efficiency has improved significantly, resulting in higher operating temperatures that negatively affect lubricating oil circulating through system. Exposure to high results degradation and eventual formation of solid deposits which greatly limit oil’s ability reduce wear cool components. An experimental apparatus was designed built allow for studying bett...

Abstract Achieving superior performance of nanoparticle systems is one the biggest challenges in catalysis. Two major phenomena, occurring during reactions, hinder development full potential catalysts: sintering and contamination with carbon containing species, sometimes called coking. Here, we demonstrate that Ir nanocrystals, arranged into periodic networks on hexagonal boron nitride (h-BN) s...

The operating conditions of injectors in spark ignition engines with direct fuel injection make them susceptible to coking, which leads a reduced quality atomization. This can be observed by drop performance and an increase exhaust emissions, especially particulate matter. One effective method reducing injector coking is using detergentdispersing gasoline additives. article describes the effect...
