This Bendable Smartphone Has A Screen Made of Graphene
Posted by Klaus Baldauf in categories: materials, mobile phones
A video of a fully bendable smartphone with a graphene touch display debuts at a Chinese trade show.
A Chinese company just showed off a fully bendable smartphone with a graphene screen during a trade show at Nanping International Conventional Center in Chongqing. Videos of the incredibly flexible phone are making the rounds, and no wonder, as it looks rather impressive.

Molecular architects: how scientists design new materials
Posted by Karen Hurst in categories: habitats, materials
When Thomas Edison wanted a filament for his light bulb, he scoured the globe collecting thousands of candidates before settling on bamboo. (It was years before people were able to make tungsten work properly.) That’s our traditional way of getting materials. We picked up stones for axes, chopped wood for housing and carved tools out of bone.

Scientists have finally made a substance that’s even stronger than graphene
Posted by Shailesh Prasad in categories: entertainment, materials
Much like in comic books, scientists are on an endless quest to discover or create the strongest, most durable substance possible. Theories about how to go about that have long circulated, but nobody has been able to overcome the challenge—until now. A team of Austrian researchers has finally worked out a way to stabilize what they are calling the strongest of all known materials, an exotic form of carbon called carbyne.

Graphene is both transparent and opaque to radiation
Posted by Shailesh Prasad in categories: internet, materials
A microchip that filters out unwanted radiation with the help of graphene has been developed by scientists from the EPFL and tested by researchers of the University of Geneva (UNIGE). The invention could be used in future devices to transmit wireless data ten times faster.
EPFL and UNIGE scientists have developed a microchip using graphene that could help wireless telecommunications share data at a rate that is ten times faster than currently possible. The results are published today in Nature Communications.
“Our graphene based microchip is an essential building block for faster wireless telecommunications in frequency bands that current mobile devices cannot access,” says EPFL scientist Michele Tamagnone.

Inertia as a zero-point-field Lorentz force
Posted by Andreas Matt in categories: materials, particle physics
Older, but interesting…
Under the hypothesis that ordinary matter is ultimately made of subelementary constitutive primary charged entities or ‘‘partons’’ bound in the manner of traditional elementary Planck oscillators (a time-honored classical technique), it is shown that a heretofore uninvestigated Lorentz force (specifically, the magnetic component of the Lorentz force) arises in any accelerated reference frame from the interaction of the partons with the vacuum electromagnetic zero-point field (ZPF). Partons, though asymptotically free at the highest frequencies, are endowed with a sufficiently large ‘‘bare mass’’ to allow interactions with the ZPF at very high frequencies up to the Planck frequencies. This Lorentz force, though originating at the subelementary parton level, appears to produce an opposition to the acceleration of material objects at a macroscopic level having the correct characteristics to account for the property of inertia. We thus propose the interpretation that inertia is an electromagnetic resistance arising from the known spectral distortion of the ZPF in accelerated frames. The proposed concept also suggests a physically rigorous version of Mach’s principle. Moreover, some preliminary independent corroboration is suggested for ideas proposed by Sakharov (Dokl. Akad. Nauk SSSR 177, 70 (1968) [Sov. Phys. Dokl. 12, 1040 (1968)]) and further explored by one of us [H. E. Puthoff, Phys. Rev. A 39, 2333 (1989)] concerning a ZPF-based model of Newtonian gravity, and for the equivalence of inertial and gravitational mass as dictated by the principle of equivalence.
