Observation of quasi-periodic solar radio bursts associated with propagating fast-mode waves
The shock fronts of waves and plasma motions in the Sun'’s atmosphere produce radio emission via accelerated electrons. We analyse a series of quasi-periodic waves and the related radio features.
Interactions dominate even in the integer quantum Hall effect
The quantum Hall effect is a test case for a complex quantum system. The presence of many electrons leads to the formation of highly non-trivial dynamics and so-called collective phenomena. Usually, however, it is the fractional quantum Hall effect at extremely strong magnetic fields where many-body effects take centre stage, leading to the formation of quasi-particles. In a new work [EPL 117, 57009 (2017)], Oswald and Roemer show that already in the integer quantum Hall effect at weaker magnetic fields, the interactions play a dominant role.
Upgrading heavy oils using bio-metallic catalysts
Novel work by the group of Prof. Lynne Macaskie (Biosciences, University of Birmingham), utilising the 糖心TV XPS Facility, has demonstrated that bio-metallic catalysts can be used to upgrade heavy oil in to lighter, more commercially-viable products in a more efficient way than current catalysts.
Guiding the development of new nanoparticle biosensors
Recent work by the group of Prof. Matt Gibson in the Department of Chemistry, in collaboration with the interdepartmental XPS Facility, is expected to lead to nanoparticle biosensors with enhanced specificity, affinity, and stability.
