How and what do we learn from molecular visualizations in science?
Subject: Visualisation and Media Technology
Lecturer: Gunnar Höst
Time: 15:15-16:00
Location: TP45, Täppan, Campus Norrköping
Abstract: Visualization holds a pivotal role in science learning, especially since so much of the content is imperceptible to the naked eye. Scientific models of the molecular world can be visualized using a multitude of visual, linguistic, and multisensory representations, ranging from images and animations to tangible models and virtual environments. In making sense of such representations, learners must leverage the properties of the visualizations into constructing knowledge of concepts such as molecules, cells and other objects and processes, which are otherwise too small to be seen. This lecture explores learners’ interaction, interpretation and learning in relation to science concepts represented by molecular visualizations. Learning will be discussed in relation to the analogical relationships between visual models and the communicated concepts from the perspectives of conceptual change, multisensory interaction with visualizations and anthropomorphism. I will provide examples of theoretical and methodological contributions to the field of science education, including presenting studies in educational contexts ranging from upper secondary school, university as well as informal learning contexts such as science centers. I will also describe how these findings might impact educational practice, visual communication and visualization design. The lecture will conclude by highlighting future avenues for research on visualization and learning.

Dynamic Automation in Production: Practical implications of adaptable robotics
Subject: Industrial Production
Lecturer: Marie Jonson
Time: 15:15-16:00
Location: ACAS, A-huset, Campus Valla
Abstract: Dynamic automation refers to the implementation of automated systems or processes that possess the capability to adapt and adjust their operations in response to changing conditions, requirements, or stimuli within their environment. Adaptable robotics in this context, denotes a specific subset of dynamic automation that focuses on robotic systems capable of adjusting their behavior, tasks, or configurations to suit changing conditions or requirements, thus increasing system resilience. This lecture explores the transformative role of adaptable robotics in modern production environments. Focused on the practical implications of dynamic automation, it elaborates on the principles of robotics and the evolving landscape of automation in manufacturing. Through case studies and practical examples, attendees gain insights into the design and implementation of dynamic automation systems capable of responding to evolving challenges and lower the threshold for automation in many applications and settings. The lecture also addresses key considerations and challenges in deploying adaptable robotics, offering a glimpse into future trends and opportunities in the field.

From chemical functionalization to green chemistry of conjugated polymers
Subject: Chemistry
Lecturer: Renee Kroon
Time: 10:15-11:00
Location: K2, Kåkenhus, Campus Norrköping
Abstract: Conjugated polymers are materials that, due to their unique chemical design, allow for interaction with electrons and photons. This property has given rise to the field of organic electronics that encompasses green technology such as solar cells and thermoelectric generators as well as wearable electronics.
With regards to the green design and synthesis of conjugated polymers, advances can still be made. Currently, most conjugated polymers are only processable from harmful organic solvents and are not designed for recycling. In addition, conjugated polymers are still synthesized from fossil fuel-based chemicals, while the selection of bio-based chemicals for conjugated monomer synthesis is not straightforward.
In this lecture, I will show how the enhancement of conjugated polymers with functional groups bestows properties such as mechanical reinforcement, water-solubility, and physical crosslinking on these materials and how these properties can be harnessed to create electroactive cellulose hybrids, which can be separated into the various components at end-of-life. With regards to the green synthesis of conjugated polymers, I will discuss what restrictions the established structural designs of conjugated polymers impose on the selection of bio-based platform chemicals and give examples of platform chemicals that can lead to bio-based conjugated monomers.
