Top 20 most exotic materials discovered or created by scientists

by

In a significant step forward for electronics innovation, researchers from Murata Manufacturing and Japan’s National Institute for Materials Science (NIMS) have unveiled a massive new database of dielectric material properties.

This extensive collection, detailed in a study published in Science and Technology of Advanced Materials: Methods, has been curated from thousands of scientific papers and is set to accelerate the development of next-generation electronics like smartphones and advanced energy storage systems.

The initiative addresses a major bottleneck in AI-driven materials discovery – the lack of large, diverse datasets. [Read more…] about Top 20 most exotic materials discovered or created by scientists

OCSiAl claims graphene breakthrough in coatings for electronic devices

by

Films play a crucial role in the consumer electronics industry, safeguarding smartphones, tablets, and laptops from scratches, fingerprints, and dust.

As the demand for such devices rises, the need for functional and aesthetically pleasing protective coatings is expanding, with a forecasted global market growth of 5.33 percent by 2027.

Graphene nanotubes offer a unique solution combining permanent conductivity and high transparency in coatings for 3C (computers, consumer electronics and communication) products without changing standard technological processes or equipment.

Swedish startup claims graphene breakthrough

by

A Swedish startup company claims it has made a breakthrough in graphene technology, a material of intense interest to many industries. 

Graphmatech, or Graphene Material Technology, a materials startup, says it is sharing its “good news” at the ongoing Hannover Messe event, where it present as co-exhibitor within Sweden Co-Lab, a place for smart innovations.

Just in time for the fair, Graphmatech says its scientists “achieved world- record values for conductive engineering plastics which has at least 100 times lower resistivity than achieved before in filaments for 3D printing”.  [Read more…] about Swedish startup claims graphene breakthrough

Opinion: Super-material graphene could lead to an electric vehicle breakthrough

by

Electric vehicle manufacturers and battery makers have long been searching for the “holy grail” technology that could lower the cost of batteries while also extending their range.

Government research labs, venture capital, startups, and large corporations have all toyed with different ways to get to the promise land.

But one material is emerging as the most promising innovation to date that could actually lead to cheap, long-range and fast-charging electric vehicles: graphite.  [Read more…] about Opinion: Super-material graphene could lead to an electric vehicle breakthrough

Graphene: A primer on the miracle material

by

Graphene is sometimes described as being two-dimensional, or 2D, which is probably more a reflection of the enthusiasm people feel about the material rather than a statement of fact since graphene is actually one atom thick. 

It may only be one single atom, but it’s still there, which means that graphene is, in fact, three-dimensional.

Another interesting thing about graphene is that the naturally occurring composite mineral it’s extracted from – graphite – has been in use for thousands of years in such things as ceramic paints, and it’s been used in pencils for decades. But only now has graphene been extracted from it and suggested for a wide array of applications.  [Read more…] about Graphene: A primer on the miracle material

Researchers create ‘extremely small’ sensor using ‘white graphene’

by

Researchers from TU Delft in the Netherlands, in collaboration with a team at the University of Cambridge, have found a way to create and clean tiny mechanical sensors in a scalable manner.

They created these sensors by suspending a two-dimensional sheet of hexagonal boron nitride (h-BN), or “white graphene” over small holes in a silicon substrate. This innovation could lead to extremely small gas and pressure sensors for future electronics.

Hexagonal boron nitride (h-BN) is an interesting material, since it has a honeycomb lattice structure similar to that of graphite. But while graphite conducts electricity, h-BN acts as an insulator.  [Read more…] about Researchers create ‘extremely small’ sensor using ‘white graphene’

Nano-chimneys can cool circuits, say Rice University scientists

by

From the Rice University website

The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like “chimney” between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.

The research appears in the American Chemical Society’s Journal of Physical Chemistry C.

Heat is transferred through phonons, quasiparticle waves that also transmit sound. The Rice theory offers a strategy to channel damaging heat away from next-generation nano-electronics.  [Read more…] about Nano-chimneys can cool circuits, say Rice University scientists
