Collection of students' reports - Complex Systems and Self-Organization (TalTech, Spring 2024)
No full text<p>The present file contains a collection of reports of the students of the <strong>Course of Complex Systems and Self-Organization</strong>,<br>given during the Spring 2024 at the Tallinn University of Technology (TalTech, Course YFX1150, “Komplekssüsteemid ja iseorganiseerumine”).</p>
<p>The course was also part of the <strong>EuroTeQ Engineering University</strong> and some of the students joined the course online from other universities connected to EuroTeQ.</p>
<p>The reports were evaluated for the final grades and were intended not only to check the students' ability to study, summarize, and present a research topic, but also to stimulate their creativity and involve them in the actual start of a (small) research project - in fact some of the topics of the reports concern original suggestions made by the students themselves. </p>
<p>Hopefully this collection has been useful for them and will be useful for the new students by providing examples and ideas.</p>

Wood Chemistry Perspectives at TalTech
No full textDespite being the most abundant renewable resource in Estonia, wood has not been fully utilized for its potential value. To fully harness its potential, wood needs to be processed to its core components, such as fibers, wood sugars, and lignin, using chemical, thermochemical, or enzymatic methods. Researchers at TalTech are working on developing a comprehensive value chain for wood valorization, encompassing the production of food additives, thermoplastics, coating materials, and fine chemicals. Traditionally, lignin, a byproduct of the wood fractionation, was burned for energy. However, TalTech researchers are now using lignin to create novel thermoplastics, catalytic materials, and fine chemicals via fermentation processes. Here we show that the conversion of lignin into novel functional materials can be tailored by selecting appropriate extraction methods and source biomass. For instance, organosolv lignin extracted from barley straw exhibits the largest BET active surface area for lignin-based aerogels compared to those produced from softwood or hardwood organosolv lignins. Additionally, we showcase the potential of actinobacterial enzymes to detoxify phenol-containing wood sugar solutions, enabling their utilization in fermentation processes involving a wider array of microbial species
