New 3D Nanoprinting strategy opens door to revolution in Medicine, Robotics

Engineers at the University of Maryland (UMD) have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction — a critical feature for products like implantable devices that release therapies directly into the body.

UMD engineers demonstrate their approach by printing the smallest-known 3D microfluidic circuit element. Engineers at the University of Maryland (UMD) have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction – a critical feature for products like implantable devices that release therapies directly into the body.

An international team led by the University of Liverpool and McMaster University has made a significant breakthrough in the search for new states of matter. In a study published in the journal Nature Physics, researchers show that the perovskite-related metal oxide, TbInO3, exhibits a quantum spin liquid state, a long-sought-after and unusual state of matter.

Using cutting-edge experimental technologies, including inelastic neutron scattering and muon spectroscopy, researchers discovered that the exotic quantum state in TbInO3 emerges from the complexity of the local environment around the magnetic ions in the material, ...

New printing technique and materials could be used to develop intelligent materials and self-adaptive infrastructures and transducers. The piezoelectric materials that inhabit everything from our cell phones to musical greeting cards may be getting an upgrade thanks to work discussed in the journal Nature Materials released online Jan 21.

Xiaoyu ‘Rayne’ Zheng, assistant professor of mechanical engineering in the College of Engineering, and a member of the Macromolecules Innovation Institute, and his team have developed methods to 3D print piezoelectric materials that can be custom-designed to convert movement, impact and stress from any directions to electrical energy...

Feathers: Better than Velcro?

You may have seen a kid play with a feather, or you may have played with one yourself: Running a hand along a feather’s barbs and watching as the feather unzips and zips, seeming to miraculously pull itself back together. That “magical” zipping mechanism could provide a model for new adhesives and new aerospace materials, according to engineers at the University of California San Diego.

Engineers detail bird feather properties that could lead to better adhesives (and aerospace materials). You may have seen a kid play with a feather, or you may have played with one yourself: Running a hand along a feather’s barbs and watching as the feather unzips and zips, seeming to miraculously pull itself back together.

That “magical” zipping mechanism coul...
