Thinnest ferroelectric material helps to produce new energy-efficient devices, researchers claim

Posted by in categories: computing, materials

“Approximately 200,000 times thinner than human hair.”

New energy-efficient devices are made possible by the thinnest ferroelectric material ever created, thanks to the University of California Berkeley and Argonne National Laboratory.

As a result of this development, intriguing material behavior at small scales could reduce energy demands for computing, revealed ANL.

Researchers create material that transforms from soft to hard when exposed to light

Posted by in categories: materials, robotics/AI

Inspired by living things, the unique material is 10 times as durable as natural rubber.

For the first time, researchers use only light and a catalyst to change properties such as hardness and elasticity in molecules of the same type, according to a new study published October 13 in Science.

The ability to control the physical properties of a material using light as a trigger is potentially transformative.

Engineers weave advanced fabric that can cool a wearer down and warm them up

Posted by in categories: materials, nanotechnology

Textile engineers have developed a fabric woven out of ultra-fine nano-threads made in part of phase-change materials and other advanced substances that combine to produce a fabric that can respond to changing temperatures to heat up and cool down its wearer depending on need.

Materials scientists have designed an advanced textile with nano-scale threads containing in their core a phase-change material that can store and release large amounts of heat when the material changes phase from liquid to solid. Combining the threads with electrothermal and photothermal coatings that enhance the effect, they have in essence developed a fabric that can both quickly cool the wearer down and warm them up as conditions change.

A paper describing the manufacturing technique appeared in ACS Nano on August 10.

Researchers develop automatic drawing machine for making paper-based metamaterials

Posted by in categories: chemistry, materials

Researchers have developed an automatic drawing machine that uses pens and pencils to draw metamaterials onto paper. They demonstrated the new approach by using it to make three metamaterials that can be used to manipulate the microwave region of the electromagnetic spectrum.

Metamaterials are artificially engineered that derive their properties from patterned microstructures, rather than the chemical composition of the materials themselves. The exact shape, geometry, size, orientation and arrangement of the structures can be used to manipulate in ways that aren’t possible with conventional materials.

“Metamaterials, especially those used as absorbers, generally need to be thin, lightweight, wide and strong, but it isn’t easy to create thin and lightweight devices using traditional substrates,” said research team leader Junming Zhao from Nanjing University in China. “Using paper as the substrate can help meet these requirements while also lending itself to metasurfaces that conform to a surface or that are mechanically reconfigurable.”
