Wideband characterization of aluminum nitride substrates and high power-high frequency thick film applications
… thick film interaction, and environmental effects on <i>AIN</i> substrates, and also to examine the performance of this material for high power - high frequency hybrid thick film applications. In particular, wideband dielectric constant measurements of A1N and other ceramic substrates are …

New Fatigue Test Method for Evaluating the Performance of Adhesive Bonded Joints
… Other specimens were also subjected to humidity effects. The outcome of the thesis delivers a new FTM, based on one specimen configuration that can be adapted as to evaluate the fatigue and environmental durability characteristics of adhesive joints under more appropriate stress …

SAW humidity sensor and an environmental electronic nose system
… frequency has been successfully applied as a humidity sensor. A YZ-cut lithium niobate substrate was used. The polymer (polyXIO) was deposited directly over the substrate or over a metal film on the substrate. A turn-around in the frequency shift and a jump in the attenuation were observed …

High throughput studies of polymer electrolyte for battery and fuel cell applications
… to be<br/>subjected to temperature and relative humidity effects. The multi-electrode cell was<br/>calibrated using commercially available Nafion samples before being used with<br/>synthesised samples. PEEK was sulfonated to SPEEK using varying temperatures and<br/>reaction times to obtain many …

Multiscale models based on statistical mechanics and physically-based machine learning for the thermo-hygro-mechanical behavior of spider-silk-like hierarchical materials
… open problems are also related to the relevant effects of environmental conditions and in particular on temperature and humidity, strongly conditioning the mechanical performances. In this thesis, aimed at unveiling some of these open problems, we introduce a multiscale model for the …

Granular Activated Carbon Sorption as a Load Equalization Mechanism in Operation of Air Pollution Control Devices
… concentrations, gas flow rates, and relative humidity. Toluene was used as model VOC, and BPL 4x6 mesh GAC was used as a model adsorbent. The research was divided into four tasks. These involved evaluation of GAC load equalization for transient loading conditions involving: (1) intermittent …

Particle Charging and Classification: The Mass Mobility Aerosol Spectrometer (M2AS)
… accuracy across various applications. While the effects of humidity on aerosol behaviour are well-recognised, their influence on particle charging has received limited attention, particularly in the context of charging sensors. In this work, the effect of humidity on particle charging behaviour …
