Casper Clausen

During his studies, Casper Clausen researched the development of new sensor technologies and rechargeable batteries by utilizing simple physical concepts and cheap organic chemicals, respectively. The two main subjects of the study, sensors and batteries, are expected to play major roles in the future, e.g. in areas like automation, industrial control, and the renewable energy sector.

One of the sensor projects was focused on the measurement of particles in liquids. The sensor uses a laser beam geometrically shaped in a specific way to measure particle concentration, size, and speed of movement. Casper also investigated another sensor principle, the so-called 3-omega method, which he found to be useful in a variety of different measurements in liquid; flow speed, liquid contact, concentration, and, maybe most noteworthy, fouling thickness.

Furthermore, he studied an organic group of chemical compounds called anthraquinones for a new use as one of the active materials in rechargeable batteries. A battery of this type will likely not be able to compete with existing batteries when it comes to size, but it has a large potential to compete on price. If large capacity batteries are to be used to store excess renewable energy in the near future, the materials cost will be much more important than the size of the battery.

The PhD degree was completed at the Department of Engineering, Science and Technology, Aarhus University.
