In this study the possibilities of the North American oak (Quercus rubra L.) as an afforestation alternative in the Basque Country Autonomous Community were investigated. The aim was to expand the range of possibilities in forestry production, avoiding monospecific plantations but, at the same time, meeting the needs of the current economy on the basis of sustainable development.
The study centred on 6 plantations of various ages in Bizkaia, firstly studying the wealth of epigeous fungi (based on sporocarps) as well as of hypogeous fungi (as ectomycorrhizals). Over a three-year period of sampling, 111 high-value species of macromycetes were studied; being grouped in 7 orders (Agaricales 60%, Russulas 18%, Boletals 14%, Polyporals 4%, Pezizales 2%, Cantharelles 1% and Phalalles 1%). The mature plantations, apart from showing a greater specific wealth, have proved to be more homogenous amongst each other than the non-mature ones. As regards ectomycorrhizals, 90 morphotypes have been described: 6 of these were identified at a species level; 1 was ascribed to a hitherto unknown morphotype and 7 to a genus. As regards the number of morphotypes, no differences were observed between mature and non-mature plantations. Winter turned out to be the season with the greatest number of morphotypes and of ectomycorrhizals types, followed by the autumn.
Also, the infective potential of the soils of the plantations was evaluated and it was observed that plantlings of 1 or 2 saps can be mycorrhized by the inoculum present in both mature and non-mature plantations.

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...
