Determination of Vibration Properties and Reliable Frequency Estimation for Synchronous Vibrations Through Improved Blade Tip Timing Techniques Without a Once-per-Revolution Sensor

open access: yesSensors
Synchronous vibrations, which are caused by periodic excitations, can have a severe impact on the service life of impellers. Blade Tip Timing (BTT) is a promising technique for monitoring synchronous vibrations due to its non-intrusive nature and ability

Exposure Experiments to Test the Kinetic Stability of 5‐hydroxymethylfurfural Oxidase (HMFO) in Different Reactor Environments

open access: yesChemCatChem, Accepted Article.
The impact of agitation on protein aggregation is often misattributed to shear stress rather than related phenomena such as cavitation and entrainment. For some time now, it has been known that shear is unlikely to harm most proteins directly. Rather, interfacial phenomena, particularly those involving dynamic gas‐liquid interfaces, are critical ...

Regionalized chemical footprint method to identify aquatic ecotoxicity hotspots of hard disk drive rare‐earth magnets

open access: yesIntegrated Environmental Assessment and Management, Volume 19, Issue 1, Page 272-283, January 2023., 2023
Abstract The chemical footprint (ChF), which combines life cycle assessment (LCA) and quantitative risk assessment principles, shows promise for exploring localized toxicity impacts of manufacturing processes, which is not achievable with LCA alone. An updated ChF method was applied to the global annual production of a hard disk drive (HDD) rare‐earth ...

Assessment of existing H2/O2 chemical reaction mechanisms at reheat gas turbine conditions [PDF]

open access: yesarXiv, 2011
This paper provides detailed comparisons of chemical reaction mechanisms of H2 applicable at high preheat temperatures and pressures relevant to gas turbine and particularly Alstom's reheat gas turbine conditions. It is shown that the available reaction mechanisms exhibit large differences in several important elementary reaction coefficients.
