Get excited for the second CUHS Students' Seminar! Now with three exciting presentations, about similarity between languages, chemistry of magnesium batteries and usage of drone-photography in archeology.
The aim of these seminars is to showcase the academic work Hungarian students, both graduates and undergraduates, do at the University and to provide them with an opportunity to speak about their work to an interested non-specialist audience.
The three speakers of this seminar are:
1) Ferenc Forman: Synthesis of Magnesium Salts for Use in Magnesium Batteries
2) Marcell Fekete: Walking the same walk
How do languages converge and why should we care?
3) Márton Gorka: Using drones for archaeology
1) Ferenc Forman:
Energy storage is one of the most crucial challenges of the next century; necessary for the transition from fossil fuels to renewables, and batteries are expected to play a vital role. Magnesium batteries are a viable option to replace their lithium counterparts, as their theoretical energy density is twice of lithium batteries. Furthermore, they are much less prone to dendrite formation and flammability, though practical and compatible anode, cathode and electrolyte materials are yet to be found. The electrolyte, which transfers magnesium ions from anode to cathode, has to be stable, nontoxic and noncorrosive. Based on the recent application of Mg(PF6)2 in magnesium battery electrolytes, and the success of pnictogenate analogues AsF6- and SbF6- in lithium batteries, magnesium salts of these two anions were explored as potential electrolytes in magnesium batteries.
2) Marcell Fekete:
Most linguists would agree, God did a lousy job at the Tower of Babel. He might have scrambled the sounds, the words and the structure, but languages remain remarkably similar, we just have to look deep enough. For one, languages seem to follow a restricted set of pathways for developing new linguistic material: mostly grammatical items expressing new meanings or functions. These grammaticalization paths (Heine & Kuteva, 2004) are worthy of in-depth investigation. Through following the trails of these linguistic developments, we might learn about the interplay of meaning and language and about human cognition. The focus of my dissertation was the ik verbs in Hungarian, verbs such as törik 'break', fekszik 'lie' and vitatkozik 'argue'. It seems that the developments concerning these verbs fit in with the cross-linguistic developments. Come by for exciting new words such as mediality, reflexivity, reciprocals, anticausatives and so on, and so on!
3) Márton Gorka:
Drones have, in recent years, started to become more widely used in archaeology, both for cheap aerial imagery and as surveying tools. After a period of custom-built drones, now it is possible to use simple, off-the-shelf consumer models to conduct accurate, high-resolution site surveys. In this talk, I will discuss how these drones, which many view as “toys”, are shaking up archaeological surveying. My project consisted of mapping the Iron Age site of Belsar’s Hill in Cambridgeshire and I compared this the previous site survey, showing how easy and quick it is to map a site with a drone. What was created as a camera for hip youtubers to make their vlogs look cool is now being used by archaeologists to accurately map and model archaeological sites in 3D.
