Three robotic arms extended under the water in a Canadian lake, delicately selecting pebbles from the bed, before storing them back inside the machine.This post was originally published on this site

For weeks, the whiteboard in the lab was crowded with scribbles, diagrams, and chemical formulas. A research team across the Olivetti Group and the MIT Concrete Sustainability Hub (CSHub) was working intensely on a key […]

Converting ammonia production to a low-emission process is one of the major challenges in the fight against climate change. Ammonia, one of the most widely produced chemicals worldwide, is essential for the fertilizer industry and, […]

Satellite-based electro-optical sensors are intended to detect missile launches early on, gaining valuable time for initiating countermeasures in case of an attack. The Fraunhofer Institute of Optronics, System Technologies and Image Exploitation IOSB is developing […]

From ship propellers to wind turbines and harvesters, seals are crucial to ensuring functionality in any technical system with moving parts. To increase their durability, they have mainly been made from plastics that contain PFAS, […]

One of the most striking patterns in the aftermath of many urban fires is how much unburned green vegetation remains amid the wreckage of burned neighborhoods.This post was originally published on this site

Researchers have created dynamic structures that leap into the air on a predetermined schedule without intervention from computers or external stimuli. Precisely when these “metashells” jump, and how high they jump, is engineered into the […]

Germany’s dependence on these critical raw materials became apparent once again following the customs dispute in April, when China restricted exports of rare-earth elements and other elements to the U.S. and, consequently, to Europe.This post […]

The water we use every day is purified in wastewater treatment plants and discharged into rivers, and in recent years, the reuse of treated water for domestic and industrial use has been expanding to solve […]

A University of Nebraska–Lincoln engineering team is another step closer to developing soft robotics and wearable systems that mimic the ability of human and plant skin to detect and self-heal injuries.This post was originally published […]
