Remote ‘marine deserts’ and dense plankton blooms could provide scientists with clues for understanding climate change.
A research team will set sail from Southampton, Friday, 17th September 2004, for the start of an expedition to study the interaction between the atmosphere and plankton – tiny floating marine organisms. By monitoring these organisms and the influence of changing climate on their growth, they hope to discover whether they act as a source of carbon dioxide, or a ‘sink’ in which the carbon is contained.
Dr Andy Rees, Principal Scientist on the ship said ‘The ship will pass close to the coast of Africa, where we hope to find large numbers of plankton, called blooms. These blooms may be due to nutrient rich water rising to the surface or to dust, laden with nutrients, blown across from the Sahara providing food for the plankton. These areas act as natural chimneys of gases which contribute to global warming. We will have the opportunity to sample some hugely contrasting environments because of the meeting of waters from the northern and southern hemispheres. We will compare this area with barren desert regions of the Atlantic where there are very small numbers of plankton.’

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
