Laser-guided self-assembly enables precise fabrication of micro-rolls for advanced applications
Apr 04, 2024 (Nanowerk Spotlight) The quest to create intricate three-dimensional microstructures has long captivated scientists and engineers, driven by the immense potential these tiny constructs hold for revolutionizing fields such as electronics, photonics, and biomedicine. However, the journey from concept to reality has been fraught with challenges. Conventional fabrication...
Galaxies get more chaotic as they age
Apr 03, 2024 (Nanowerk News) An international team led by Australian research centre ASTRO 3D reports that age is the driving force in changing how stars move within galaxies. Galaxies start life with their stars rotating in an orderly pattern but in some the motion of stars is more random....
Intelligent liquid
Apr 04, 2024 (Nanowerk News) Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a programmable metafluid with tunable springiness, optical properties, viscosity and even the ability to transition between a Newtonian and non-Newtonian fluid. The first-of-its-kind metafluid uses a suspension of small,...
‘Smart swarms’ of tiny robots inspired by natural herd mentality
Apr 03, 2024 (Nanowerk News) In natural ecosystems, the herd mentality plays a major role – from schools of fish, to beehives to ant colonies. This collective behavior allows the whole to exceed the sum of its parts and better respond to threats and challenges. This behavior inspired researchers from...
