  • Introduction: Large-scale chemical, food, and biological process facilities all suffer from similar problems: They produce a substance in a large reaction tank, which undergoes a range of different processing steps. At the end of each step, it is essential to understand and filter out the substance of interest from the background liquid in the tank. For example, a common filtering mechanism is to make the substance form aggregates (called “flocculation,” see figure 1) in the tank. These aggregates can sink to the bottom and be isolated for further processing. However, in many of the process steps, manufacturers have minimal access to information about the state of the process in the tank. Therefore, much attention is paid to finding new optical methods that can help monitor and understand these processes.
  • Aim of the project: In the project, the student will utilize a THz-TDS system to look at various water-based liquid systems like those found in large processing tanks. The aim is to controllably vary the content of various constituents in the liquids and investigate whether THz-TDS can capture these changes. The underlying data processing models will be machine-learning based. It is not required that the student has prior knowledge about machine learning to undertake this project; in that case, it is an excellent opportunity to learn about machine learning by using it.
  • The team: This project will be carried out in our newly established THz Innovation Center at DTU Electro. The center consists of 8 researchers with different backgrounds, all working together to make THz technology available to everyone worldwide. The student will be part of the group’s day-to-day work, which ensures a large amount of support. The student is also invited to partake in the group’s social activities, such as everyday lunches, after-work beers, etc.

One of the emerging optical methods is terahertz time-domain spectroscopy (THz-TDS). The method is interesting because it inherently probes interactions between molecules, and it can therefore give insight into chemical reaction kinetics. Most prominently, THz interacts strongly with water and anything that forms chemical bonds to water.

Terahertz is the part of the electromagnetic spectrum that resides between microwaves and infrared. It is historically under-exploited in the industry due to a lack of suitable technology. At DTU Electro, we are alleviating this problem by developing better technology and demonstrating the fantastic value that THz radiation can provide to society.

The student will learn how to work in a structured manner in an optical laboratory to acquire high-quality data. The student will have the option to build the liquid sample handling system, which could, for example, be a flow cell. All data acquisition is handled with a commercial THz system to allow optimal time for the student to understand the chemical/biological liquids and to set up suitable machine-learning models.

This project's scope is well suited for an MSc thesis for one student or a BSc thesis where two students form a group. One very ambitious and skilled BSc student can also undertake it in a 20 ECTS point project.
Prerequisites: The activities to be conducted requires that the student is both well-accomplished academically and is driven by curiosity in all her/his work. No particular courses are required. Whatever knowledge the student will be needing, our extensive team will teach.

Contact: We would love to meet with interested students for a cup of coffee and to explain the project in more detail. If interested, please send an e-mail to Simon at [email protected]
