This course explores international arbitration as one of the most common methods of international dispute settlement. You will gain an in-depth understanding of international arbitration through the analysis of its role as a mechanism of dispute settlement, its institutions, the fields of law it is…

From publishing students, to addressing bottlenecks in education logistics and a completely new bachelor’s programme. Scroll through our highlights on educational innovation and achievements of our outstanding students.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

Making an impact by creating solutions for the challenges of the future. That’s what we do through our education and research in biodiversity and sustainability, artificial intelligence, complex networks, new medicines, quantum technology, and galaxies.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Can the conditioning paradigm be used for checkpoint inhibition cancer treatment?

Positive expectations can influence sensations of itch and evoke placebo effects, whereas negative expectations can trigger nocebo effects in itch. There is evidence that placebo effects can occur even when people know that they are taking a placebo. Little is known about how these so-called open-label…
