Are you interested in writing your research paper (research project/master thesis) in one of the research fields of ISAH?

Here you can find the currently available topics for research papers. Our current topics are divided into four research fields:

Wastewater
Solid waste and circular economy
Microbiology
Drinking water

Besides, you can also have a look on our current reasearch projects and inform us in which you are most interested.

Wastewater

SA/RP: Mobilisation of (microplastic)particles on and infiltration into permeable pavements depending on the rainfall intensity and duration

Tasks:
- Description of the particle mobilisation mechanisms on the surface.
- Which parameters are (also) important for the water driven transport of particles?
- How can maintenance measures influence the mobilisation/vertical penetration/removal of particles?
Type of work:

Seminararbeit or Research Project

MA: Investigation and optimization of biochar adsoption capacity for heavy metals and inert COD removal from landfill leachate by using response surface methodology
Tasks:
Literature review on the existing leachate treatment technologies considering biological (aerobic/anaerobic) and physical/chemical treatment options
Literature review on biochar adsorption for the removal of heavy metals and inert COD in wastewater
Brief description of response surface methodology (RSM) for experimental design optimization
Develop model equations for removal efficiency of heavy metals and inert COD
Recommendation of an investigation protocol for laboratory tests on the use of biochar in the removal of heavy metals ad inert COD

RP/SA/MA: Multi-variate principal component analysis of transition bio-chars using MID-IR ATR

Background:

As part of an Indo-German Research Project, the institute is doing a detailed research on biochar characteristics from complex substrates. As part of this, IR spectroscopy is to be deployed for a quantification of principal components using statistical/chemometric techniques like PLS and PCR. The work would start as a project arbeit, which can then progress on to a masters thesis.

Type: RP/SA/MA

Language: English

Pre-requisites: Good knowledge in chemistry, and Matlab.
