Removal of Nitrogen Based Pollutants From the AmmoniaDrive Exhaust

As the shipping industry needs to become greener, it has to move away from fossil fuels. For deep-sea shipping, ammonia is marked as a high potential fuel. The AmmoniaDrive concept feeds the anode-off gas from a Solid Oxide Fuel Cell (SOFC) and additional ammonia into an Internal Combustion Engine (ICE). The exhaust gas coming from the ICE can...

Fate of Hydroxylamine in the Nitrogen Cycle

One of the least studied nitrogen compounds is hydroxylamine. Hydroxylamine<br/>is a highly reactive and toxic inorganic compound that some microorganisms use<br/>as intermediate during nitrogen conversions. The aim of this thesis was to further<br/>understand the role of hydroxylamine in the nitrogen cycle.

The quest for specialist N2O-respiring bacteria

Nitrous oxide (N2O) is a potent greenhouse gas, and its stratospheric concentration is already 20% above the pre-industrial level. Over 70% of N2O is produced by microbial processes. Nitrous oxide reductase is the only enzyme able to reduce N2O to innocuous N2. The high abundance of organisms harbouring it and lacking the genetic potential to...

Providing analgesic laughing gas during birth in a home environment

This master thesis report, authored by Eva Schuurmans in 2016, lays the foundation for the development of a product that enables midwives in the Netherlands who facilitate births at home, to administer analgesic laughing gas to relief women in childbirth from pain. In this thesis, Eva presents a product concept that meets the strict regulations...

Predicting the diffusivity of CO2 in substituted amines

The experimental determination of the diffusivity of carbon dioxide (CO2) in an amine solvent is difficult as the CO2 diffuses and reacts simultaneously when absorbed into an amine solvent. As the knowledge of the diffusivity and solubility of CO2 is essential to design the absorption units based on amine solvents, the nitrous oxide (N2O)...
