This week's magnitude 7.8 earthquake in the Philippines came with scenes familiar to New Zealanders: collapsed buildings, shattered facades and streets strewn with rubble.
Researchers from Plasma Technology and Surfaces, Paint/Lacquer Technology, as well as Automation and Production Technology at Fraunhofer IFAM, in collaboration with HYTANK project partners, developed resource-efficient manufacturing and joining technologies for the production of large-format, double-walled hydrogen tanks made of carbon fiber-reinforced plastic (CFRP)—ranging from suitable surface…
The photoacoustic effect has been known for more than 150 years: Gases exposed to light heat up. Pulsing the light generates periodic pressure fluctuations, or sound waves, with frequencies that can be uniquely assigned to individual gases. This photoacoustic effect forms the basis for a measurement method that is highly precise even at low gas concentrations. Despite its high sensitivity, the…
Autonomous vehicles are already a reality on some of our streets and could become a major part of future transportation systems. Safety, of course, is the main concern, as with all vehicles. To help evaluate and improve its autonomous driving technology, U.S. driverless vehicle company Waymo has created a virtual representation of human driver behavior in near-crash situations.
Every underground coal mine has one thing in common: Coal seams leak methane gas into the tunnel network, presenting a serious safety hazard. The control is the same the world over: continuously pump fresh air through the workings, diluting and pushing out the methane. High-volume mechanical ventilation systems are a cornerstone of mine safety, but they create a stubborn environmental problem.
Hydrogen could be the key to a clean energy future, but a tiny problem has been holding it back: bubbles. In a paper published in Energy & Environmental Science, a multidisciplinary team of UNSW researchers, in collaboration with researchers from TotalEnergies and EPFL, has found a new way to boost the efficiency of green hydrogen production.
