Copper doping solves long-standing issue of stacking faults in β-NaMnO2 electrodes
Tokyo University of Science researchers showed how copper doping can stabilize stacking faults in β-NaMnO2, a material used for cathodes in sodium-ion batteries.
3D-printed steel capsules endure nuclear reactor testing
Oak Ridge National Laboratory researchers set a new milestone in nuclear component innovation, successfully testing two 3D-printed stainless steel experimental capsules at the lab’s High Flux Isotope Reactor.
ENVIRONMENT
Nature-inspired thermally responsive cementitious composites
Drawing inspiration from the veinous ears of jackrabbits and elephants, Drexel University researchers embedded a vascular network within cement-based building materials that, when filled with paraffin-based material, can help passively regulate the surface temperature of walls, floors, and ceilings.
Dinosaur-age marine reptile flippers could solve aquatic noise pollution
Palaeontologists proposed that ships could employ a system used by ancient marine reptiles to reduce human-induced noise pollution in aquatic environments.
Seaweed-infused cement could cut concrete’s carbon footprint
Researchers at the University of Washington and Microsoft developed a new type of low-carbon concrete by mixing dried, powdered seaweed with cement. The seaweed-fortified cement has a 21% lower global warming potential while retaining its strength.
MANUFACTURING
Researchers identify most efficient reinforced concrete beam design
Researchers from Florida Atlantic University, the Metallurgical Institute in Ukraine, and Ariel University in Israel applied Dolinsky’s corrosion model to determine that the most efficient design for reinforced concrete beams uses the smallest possible amount of material while still ensuring the structure remains strong and functional.
Study aims to help semiconductor industry be more sustainable
A yearlong collaborative research project between Cargill Bioindustrial and Arizona State University is looking into how a plant-derived material might improve the performance and sustainability of semiconductor technologies.
This AI-powered lab runs itself—and discovers new materials 10x faster
Researchers at North Carolina State University demonstrated a new technique that allows “self-driving laboratories” to collect at least 10 times more data than previous techniques at record speed. It makes use of dynamic flow experiments, where chemical mixtures are continuously varied through the system and are monitored in real time.
A smarter approach to designing metamaterials
Researchers led by the University of California, Berkeley developed a new artificial intelligence-driven framework that can more efficiently design 3D truss metamaterials. Their patent-pending modeling method, dubbed GraphMetaMat, uses deep learning techniques to bridge the gap between metamaterials design and manufacturability.
