Robotics and additive manufacturing used to produce tougher concrete
Taking inspiration from nature, researchers from Princeton Engineering have improved crack resistance in concrete components by coupling architected designs with additive manufacturing processes and industrial robots that can precisely control materials deposition. The designs increased resistance to cracking by as much as 63 per cent compared to conventional cast … [Read more...] about Robotics and additive manufacturing used to produce tougher concrete
Researchers make breakthrough in smart fabric for sensing and energy harvesting
Researchers at the University of Waterloo in Ontario have developed a smart fabric that has potential for use in energy-harvesting, health-monitoring and movement-tracking applications. The new fabric can convert body heat and solar energy into electricity, potentially enabling continuous operation with no need for an external power source. Different sensors monitoring … [Read more...] about Researchers make breakthrough in smart fabric for sensing and energy harvesting
Forever chemicals removed from water with 3D-printed ceramic ‘monoliths
Researchers at the University of Bath have created ceramic-infused lattices (or ‘monoliths’), that can remove at least three-quarters of perfluorooctanoic acid (PFOA), one of the most common perfluoroalkyl and polyfluoroalkyl substances (PFAS), from water and could become an important tool in future efforts to eliminate the chemicals from water supplies. Known as forever … [Read more...] about Forever chemicals removed from water with 3D-printed ceramic ‘monoliths
Eco-friendly 3D concrete printing takes a step forward
A research team led by engineers at the University of Virginia School of Engineering and Applied Science is exploring how an emerging plant-based material known as cellulose nanofibrils could amplify the benefits of 3D-printed concrete technology. “The improvements we saw on both printability and mechanical measures suggest that incorporating cellulose nanofibrils in … [Read more...] about Eco-friendly 3D concrete printing takes a step forward
