New skills of Graphene: Tunable lattice vibrations

Mon, 2021-03-01 20:29
Technological innovation in the last century was mainly based on the control of electrons or photons. Now, in the emerging research field of phononics, phonons or vibrations of the crystal lattice attract attention. A team showed a graphene-based phononic crystal whose resonant frequency can be tuned over a broad range and has used a helium-ion microscope to produce such a crystal. This is a real breakthrough in the field of phononics.

The technology, which uses organic light-emitting diodes (OLEDs), is applied in the same way as water transfer tattoos. That is, the OLEDs are fabricated on to temporary tattoo paper and transferred to a new surface by being pressed on to it and dabbed with water.

Scientists induce artificial 'magnetic texture' in graphene

Fri, 2021-02-26 00:57
Graphene is not magnetic -- a shortcoming that has stunted its usefulness in spintronics, an emerging field that could rewrite the rules of electronics, leading to more powerful semiconductors and computers. Researchers report an advancement to overcome this obstacle. They describe pairing a magnet with graphene, and inducing what they call 'artificial magnetic texture' in the nonmagnetic wonder material.

Materials scientists show way to make durable artificial tendons from improved hydrogels

Wed, 2021-02-24 22:33
Materials scientists and their colleagues have developed a new method to make synthetic biomaterials that mimic the internal structure, stretchiness, strength and durability of tendons and other biological tissues.

An intelligent soft material that curls under pressure or expands when stretched

Wed, 2021-02-24 22:00
Plants and animals can rapidly respond to changes in their environment, such as a Venus flytrap snapping shut when a fly touches it. However, replicating similar actions in soft robots requires complex mechanics and sensors. Now, researchers reporting have printed liquid metal circuits onto a single piece of soft polymer, creating an intelligent material that curls under pressure or mechanical strain.

Fabricating the future with a new environment friendly method of polymerization

Wed, 2021-02-24 20:38
The current use of metal catalysts to develop polymers leads to suboptimal quality polymers that contain metallic impurities and involves a reaction process that is not environment friendly. Now, scientists have successfully demonstrated the room temperature formation of vinyl and styrene polymers -- two most abundantly found polymers in plastics -- using non-ionic, non-metallic organocatalysts, which pave the way for a low cost, environment friendly, efficient polymer-driven future.

Spintronics: New production method makes crystalline microstructures universally usable

Tue, 2021-02-23 21:37
New storage and information technology requires new higher performance materials. One of these materials is yttrium iron garnet, which has special magnetic properties. Thanks to a new process, it can now be transferred to any material. Developed by physicists, the method could advance the production of smaller, faster and more energy-efficient components for data storage and information processing.
