Growth Under Pressure: New Metamaterial Designed with Counterintuitive Property

Inspired by 3-D printing, researchers explored development of one mechanical property called effective static compressibility. As they now report in Applied Physics Letters, by using a single cartridge it’s possible to print a metamaterial which expands in size under hydrostatic pressure, even though it’s made up of material which behaves normally under hydrostatic pressure -- that is, it shrinks. In principle, there is no limit to the negative value this material’s effective compressibility can take.

Freezing Lithium Batteries May Make Them Safer and Bendable

Yang-NanoLetterflexiblelithiumbatteryVISUAL.png

Columbia Engineering Professor Yuan Yang has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing new possibilities such as flexible smartphones. His new technique uses ice-templating to control the structure of the solid electrolyte for lithium batteries that are used in portable electronics, electric vehicles, and grid-level energy storage. The study is published online April 24 in Nano Letters.

New Study Reveals the Mystery Behind the Formation of Hollowed Nanoparticles During Metal Oxidation

Hollowed_Nano_900px.jpg

In a newly published Science paper, Argonne and Temple University researchers reveal new knowledge about the behavior of metal nanoparticles when they undergo oxidation, by integrating X-ray imaging and computer modeling and simulation. This knowledge adds to our understanding of fundamental processes like oxidation and corrosion.

Ultrafast Imaging Reveals the Electron’s New Clothes

BES-2017-04-h-lrg.jpg

Scientists use high-speed electrons to visualize “dress-like” distortions in the atomic lattice. This work reveals the vital role of electron-lattice interactions in manganites. This material could be used in data-storage devices with increased data density and reduced power requirements.

One Small Change Makes Solar Cells More Efficient

BES-2017-04-g-lrg.jpg

For years, scientists have explored using tiny drops of designer materials, called quantum dots, to make better solar cells. Adding small amounts of manganese decreases the ability of quantum dots to absorb light but increases the current produced by an average of 300%.
