A mobile sampling and measurement system for the analysis of gaseous and liquid samples in the field was developed. An inductively coupled plasma optical emission spectrometer (ICP-OES), which is built into a van, was used as detector. The analytical syste ...
When using natural or waste wood in thermo-chemical conversion processes, the presence of a number of heteroatoms (e.g. sulfur, chlorine, potassium and sodium or heavy metals) may hinder the processes themselves as well as pose a threat to equipment and/or ...
Acidic in situ recovery (ISR) of uranium is utilized because of its potential to be much cleaner than traditional physical mining techniques. Instead of spreading uranium-laden waste rock across soil, ISR circulates acid below the surface of the Earth with ...
Real time tip clearance measurement in gas turbines and other rotating machinery is an interesting way to provide enhanced reliability, cost effective maintenance and more overall safety. This paper presents a novel microwave sensor for blade tip clearance ...

The water-soluble Ru(II)-phosphine complex, [{RuCl2(mTPPMS)(2)}(2)] was found a suitable catalyst for the hydrogenation of NaHCO3 to NaHCO2 in aqueous solution under mild conditions with catalyst turnover frequencies (TOFs) in the range of 35-50 h(-1) at 5 ...
An integrated system of a microreformer and a carrier allowing for syngas generation from liquefied petroleum gas (LPG) for micro-SOFC application is discussed. The microreformer with an overall size of 12.7 mm × 12.7 mm × 1.9 mm is fabricated with micro-e ...
The selective dehydrogenation of aqueous solutions of HCOOH/HCOONa to H2 and CO2 gas mixtures has been investigated using RuCl3·3H2O as a homogeneous catalyst precursor in the presence of di␣erent monoaryl-biaryl or alkyl-biaryl phosphines and aryl diphosp ...
We present a far infrared gas spectrometer which uses a thin film pyroelectric detector integrated on silicon. The detector is in-house fabricated and consists of 1 x 50 elements of sol-gel deposited, zirconium rich lead titanate (PZT) which are suspended ...
Modern material technology relies increasingly on processes for surface modification and coating. Generally, we are lacking a possibility to monitor the progress of such processes. Thus the outcome can only be analyzed after the end of the whole process cy ...
