Scientists create self-healing 3D building blocks
Scientists have created 3D building blocks that can heal themselves in response to damage.
The engineered living materials (ELMs) exploit biology's ability to heal and...
High-speed camera captures a water jet’s splashy impact as it pierces a droplet
Squirting a jet of water through a drop of liquid may sound like idle fun, but if done precisely, and understood thoroughly, the splashy...
Tandem solar cells could help convert more energy from sun
Many countries around the world are committed to reducing emissions or reaching net-zero emissions to meet the United Nations' climate goals of maintaining temperature...
Woven nanotube fibers could turn heat into power, shows study
Invisibly small carbon nanotubes aligned as fibers and sewn into fabrics become a thermoelectric generator that can turn heat from the sun or other...
Polymer helps make tougher recyclable thermoplastics
To synthesize plastic, small monomer molecules need to be strung together like beads in a necklace, creating long polymer chains.
However, not all plastics –...
This material inspired by chain mail could transforms from flexible to rigid on command
Engineers at Caltech and JPL have developed a material inspired by chain mail that can transform from a foldable, fluid-like state into specific solid...
Want to swim like a fish? Engineers uncover the secrets of fish fins
Peer into any fishbowl, and you'll see that pet goldfish and guppies have nimble fins.
With a few flicks of these appendages, aquarium swimmers can...
Scientists find new way to quadruple microbatteries’ energy density
Weighing about as much as two grains of rice but with the energy density of a much larger, heavier battery, the researchers’ packing-free design...
New sensor could detect when firefighters’ protective clothing is no longer safe
Firefighters risk their lives battling blazes, and aging protective gear can put them at even greater risk.
A University of Alberta researcher is working with...
New material offers ecofriendly solution to converting waste heat into electricity
Perseverance, NASA’s 2020 Mars rover, is powered by something very desirable here on Earth: a thermoelectric device, which converts heat to useful electricity.
On Mars,...
