An efficient self-assembly process for advanced self-healing materials

Tue, 04/01/2025 - 10:13am
Self-healing coatings are advanced materials that can repair damage, such as scratches and cracks on their own. Researchers have developed an efficient method for preparing self-healing films consisting of alternating layers of highly cross-linked organosiloxane and linear polydimethylsiloxane (PDMS). Their film is more durable than conventional self-healing PDMS materials, offering superior hardness and greater thermal stability while self-healing at mild temperatures, paving the way for stronger, more reliable, and easier-maintained self-healing materials.

Physicists use quantum entanglement to crack mystery of strange metals

Fri, 03/28/2025 - 2:35pm
Scientists have long sought to unravel the mysteries of strange metals -- materials that defy conventional rules of electricity and magnetism. Now, a team of physicists has made a breakthrough in this area using a tool from quantum information science. The study reveals that electrons in strange metals become more entangled at a crucial tipping point, shedding new light on the behavior of these enigmatic materials. The discovery could pave the way for advances in superconductors with the potential to transform energy use in the future.

Artificial neurons organize themselves

Fri, 03/28/2025 - 2:29pm
Novel artificial neurons learn independently and are more strongly modeled on their biological counterparts. A team of researchers has programmed these infomorphic neurons and constructed artificial neural networks from them. The special feature is that the individual artificial neurons learn in a self-organized way and draw the necessary information from their immediate environment in the network.

Smart textiles and surfaces: How lightweight elastomer films are bringing tech to life

Fri, 03/28/2025 - 8:28am
Clothes that can mimic the feeling of being touched, touch displays that provide haptic feedback to users, or even ultralight loudspeakers. These are just some of the devices made possible using thin silicone films that can be precisely controlled so that they vibrate, flex, press or pull exactly as desired. And all done simply by applying an electrical voltage.

Physics of irregular objects on inclined planes probed

Thu, 03/27/2025 - 1:45pm
How gravity causes a perfectly spherical ball to roll down an inclined plane is part of elementary school physics canon. But the world is messier than a textbook. Scientists have sought to quantitatively describe the much more complex rolling physics of real-world objects. They have now combined theory, simulations, and experiments to understand what happens when an imperfect, spherical object is placed on an inclined plane.

The hidden spring in your step

Thu, 03/27/2025 - 11:20am
Researchers reveal the way our legs adapt to fast movements. When people hop at high speeds, key muscle fibers in the calf shorten rather than lengthen as forces increase, which they call 'negative stiffness.' This counterintuitive process helps the leg become stiffer, allowing for faster motion. The findings could improve training, rehabilitation, and even the design of prosthetic limbs or robotic exoskeletons.
