H2O and O2
Monitoring of gas in the lungs and intestines of newborn infants: H2O and O2

Child mortality is high among preterm newborn infants. They are often affected by free gas in lungs and intestines, which may lead to the breakdown of vital organs. The current diagnosis is based on X-ray radiography. According to a study a bed-side, rapid, non-intrusive, and gas-specific technique for in vivo gas sensing would improve diagnosis and enhance the babies' chance of survival. The detection method is based on laser spectroscopy

O2
Power maximization of hypersonic aircraft engines: O2

The maximum power, fuel efficiency and stability of hypersonic aircraft engines depend on the captured air volume. Monitoring the oxygen concentration and velocity are important measures to define the airflow.

O2 and CO
Combustion control in high temperature processes: O2 and CO

Oxygen control enhances process and cost efficiency of incinerators. Oxidation requires excess air. But too much air cools down the combustion and increases the amount of CO in the flue gas. Real-time and in situ monitoring helps to optimize the oxygen content in combustion processes.
