An automatic sprinkler system significantly increases a persons chances of surviving a dormitory fire, according to a report issued recently by the National Institute of Standards and Technology (NIST).

Three NIST experiments,* supported by a U.S. Fire Administration (USFA) initiative for fire safety in college housing, compared the hazards of fires in smoke detector-equipped dormitories with and without fire sprinklers in the room of fire origin. Researchers started fires in a day room or lounge area open to the corridor of a dormitory. They used the temperature of 120 degrees C (248 degrees F) as the cutoff mark for human survival. For comparison, the temperature of boiling water is 100 degrees C.
In two experiments without sprinklers, potentially fatal temperatures exceeding 120 degrees C as well as toxic gases reached a remote corridor 22.9 meters (75 feet) away within three minutes and completely spread throughout the corridor within another three minutes. In an experiment with sprinklers, temperatures at the 1.5 meter (five feet) level and below in the room where the fire began never exceeded 120 degrees C. No significant increase in heat was measured in the corridor during the experiment, allowing adequate time for residents to escape.

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

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...
