The Weakness of Robustness

Zeolites as coating materials for Fiber Bragg Grating chemical sensors for extreme conditions

Important progress has been made towards the expanding of the limits of applicability of Fiber Bragg Grating (FBG) optical sensors. The development of new inorganic coatings consisting of MFI zeolite crystals (silicalite and ZSM-5) has opened up the possibility towards the use of this technology at high temperatures and pressures. Using two...

Assessment of stability of propellants and safe lifetimes

The surveillance of gun propellants is basically performed either by an investigation into the thermal behavior of the propellant or by the determination of its remaining effective stabilizer content. Over the years it is shown that the surveillance of NC based gun propellants is necessary. NC based materials are intrinsically unstable, and can...

Acid wash scrubbing as a countermeasure for ammonia emissions from a postcombustion CO2 Capture Plant

Amine-based absorption-desorption processes are considered to be the state-of-the-art technology for CO2 capture. However, the typical amines used are susceptible to oxidative and thermal degradation. Ammonia is formed as a result of oxidative solvent degradation. Because of the volatility of ammonia, significant emissions of ammonia can occur....

A novel approach to tribological measurements at harsh conditions

When dealing with high-tech equipment, accurate positioning is of the utmost importance to ensure durability and a productive lifetime. Unexpected high friction or wear of positioning mechanisms can lead to unnecessary down-time or products that are not up to specification. To ensure a sufficient lifetime, it is necessary to know beforehand how...

The climatic-altitude chamber as development and validation tool

Two major trends can be identified for powertrain control in the next decade. The legislation will more and more focus on in-use emissions. Together with the global trend to reduce the CO 2 emissions, this will lead to an integral drive train approach. To develop and validate this integral drive train approach, the need for a new chapter in...
