Expert European organizations have united to create the world's first database of valuable materials available for 'urban mining' from scrap vehicles, spent batteries, waste electronic and electrical equipment, and mining wastes. The Urban Mine Platform (urbanmineplatform.eu), created by 17 partners in project ProSUM (Prospecting Secondary Raw Materials in the Urban Mine and Mining Wastes), presents the flows of precious and base metals and critical raw materials in products in use and throughout their journey to end of life.
In research published today in Advanced Materials, a group of researchers led by UC Riverside's David Kisailus has identified a unique structure that wraps around the mantis shrimp's club to protect it from self-inflicted damage as it crushes hard-shelled prey. The finding will help Kisailus' team develop ultra-strong materials for the aerospace and sports industries.
'The beauty of this research is that someone using only a laptop and an object that flickers can detect if someone is using a drone to spy on them,' says Ben Nassi, a Ph.D. student in the BGU Department of Software and Information Systems Engineering and a researcher at the BGU Cyber Security Research Center (CSRC). 'While it has been possible to detect a drone, now someone can also tell if it is recording a video of your location or something else.'
A new 3-D printing technique allows researchers to replicate biological structures, which could be used for tissue regeneration and replica organs.
If a community is resilient, it can withstand and recover from an unanticipated disaster, like an earthquake, fire or flood. But since every disaster and every community is unique, a uniform measure for defining 'resilience' has been hard to come by for engineers and social scientists. A new study offers an innovative approach to defining resilience that could help communities better prepare for hazards.
Drivers' limited capacity to process the myriad details they absorb could explain why they sometimes fail to avoid crashes with motorcycles.
A new class of soft, electrically activated devices is capable of mimicking the expansion and contraction of natural muscles. These devices, which can be constructed from a wide range of low-cost materials, are able to self-sense their movements and self-heal from electrical damage, representing a major advance in soft robotics.
Material scientists at Ruhr-Universität Bochum are able to determine if a new material remains stable under temperature load within the space of a few days. They have developed a novel process for analysing, for example, the temperature and oxidation resistance of complex alloys that are made up of a number of different elements. Previously, such analyses used to take months. The team describes the process in the journal "Materials Horizons".
In a new paper appearing in IEEE Access, members of the Camera Culture group at MIT's Media Lab present a new approach to time-of-flight imaging that increases its depth resolution 1,000-fold. That's the type of resolution that could make self-driving cars practical.
Rosie has been the archetypal representative of helper robots since she wheeled onto televisions screens in the early 1960s. While Rosie vacuumed and washed dishes without a hint of incoordination, it turns out her real-world counterpart is far more likely to tip over and become a hindrance instead of a helper. Researchers from the King Fahd University of Petroleum & Minerals have proposed a control design of the wheeled inverted pendulum assistant robot called I-PENTAR.
