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.
