The traditional methods of fighting metal fires are not always safe for firefighters. The sand and salts that are thrown onto the fire to suffocate the flames can lead to splashes of molten metal, putting the firefighters and the surroundings at risk. A novel process is described where magnesium fires are brought under control using a simple two-st...

A novel technique for the in situ removal of mineral hydrocarbons from aged brownfields is described. The approach uses emulsions of plant oil (5–10%, rapeseed) in water, which were found to extract 50–85% of mineral hydrocarbons in one leaching step from the non-saturated zone. The emulsion was allowed to travel though the ground and was pumped of...

In tropical fruits such as durian (Durio zibethinus) and jackfruit (Artocarpus heterophyllus), only one quarter to one third of the fruit is edible. Finding more ways to industrially use the other components of the fruit can reduce the waste burned or dumped in landfills. Another fruit tree of interest that can also grow in Austria is the fig tree...
