The result of a research study performed by Rickard Hansen at Mälardalen University (MDH) in Sweden can lead to improved fire safety and evacuation safety of the mining personnel. The most common form of subterranean fires is vehicle fires in mines. Richard Hansen has in his research found out how to predict how these fires behave and develop.
Until today there have not been any extensive and in-depth studies regarding fires in mines, except for coal mines. Rickard Hansen is now changing this through his doctoral thesis "Study of heat releases rates of mining vehicles in underground hard rock mines”.
In his study of fire safety in underground mines, he demonstrates the possibility of calculating the total fire effect for mining vehicles
- These are results that society can benefit from, foremost when designing different fire rescue systems in the mines, such as mobile refuge chambers, stationary refuge chambers and smoke evacuation fans.
The air supply of the mobile refuge chambers and the stationary refuge chambers can be made larger to last longer. One could also increase the number of fans, place them closer together and make them stronger.
Thanks to this new knowledge we can improve the capacity and location of the system. This means increased fire safety and evacuation safety of mining personnel. The results could save lifes, says Rickard Hansen.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
