Extending Excitation Time for Detonation Prevention: Mixture Effect in Dimethyl Ether Auto‐Ignition

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Undesired detonation development is an obstacle in the development of modern combustion systems based on auto‐ignition. Excitation time is one of two time scales that affect detonation development. It describes the time interval, during which heat is released.

Characterizing the response time of unpumped oxygen optodes for profiling applications

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The response times of the Aanderaa 4330, Aanderaa 4330 WTW, RBRcoda T.ODO|slow, and PyroScience PICO‐O2‐SUB were evaluated in the laboratory over a range of profiling speeds at two temperatures. The PyroScience PICO‐O2‐SUB had the fastest response time (1–4 s), followed by the RBRcoda T.ODO|slow (~ 15–35 s), Aanderaa 4330 (~ 30–60 s), and ...

Investigating CMAS corrosion in ultrahigh temperature Hf6Ta2O17‐based thermal barrier coatings: A mechanism by which corrosion products hinder corrosion resistance

open access: yesMaterials Genome Engineering Advances, EarlyView.
During the corrosion of Hf6Ta2O17 by CMAS, stable corrosion products—CaTa2O6 and HfSiO4 form at the interface, which hinder further corrosion of Hf6Ta2O17 by CMAS. This mechanism successfully explains the excellent CMAS corrosion resistance of the Hf6Ta2O17 thermal barrier coating.
