This electron microscope image shows tiny nanoparticles of bismuth ferrite embedded in a polymer film. The film enhances the unique electric and magnetic properties of bismuth ferrite and preserves these properties even when bent.
The researchers describe the film in a paper published in Applied Physics Letters AIP Publishing.
Flexible electronics have been hard to manufacture because many materials with useful electronic properties tend to be rigid.
The solution was dried in a series of steps at increasing temperatures to produce a thin flexible film.
When the researchers tested the electric and magnetic properties of the film they found that their new material not only preserved
Furthermore the improved properties remained even as the film was curved into a cylindrical shape. Bulk bismuth ferrite has crucial problems for some applications such as a high leakage current
and also gave the film flexible stretchable properties. Multi-ferroric materials such as this could be used in high-density energy efficient memory and switches in wearable devices.
The results are reported in a paper published online by the Journal of Nanophotonics on May 21. hey are certainly smaller than any of the spirals wee found reported in the scientific literature,
and it is notoriously difficult and expensive to fabricate thin films of 2-D materials at such a scale
Before making a thin film of it, the scientists first had to achieve an even dispersion of the material.
The researchers then used an out-of-the-box innovation to produce high-quality thin films:
and the thin film was transferred to a flexible plastic support, which is much less expensive than a traditional solar panel.
The thin film produced like this was tested and found to be superior in efficiency to films made with the same material
but using other comparable methods. At this proof-of-concept stage the direct solar-to-hydrogen conversion efficiency was around 1%lready a vast improvement over thin films prepared by other methods,
and with considerable potential for higher efficiencies in the future. More importantly, this liquid-liquid method can be scaled up on a commercial level. t is suitable for rapid and large-area roll-to-roll processing,

#Graphene-based film can be used for efficient cooling of electronics Researchers have developed a method for efficiently cooling electronics using graphene-based film.
The film has a thermal conductivity capacity that is four times that of copper. Moreover, the graphene film is attachable to electronic components made of silicon,
which favours the film's performance compared to typical graphene characteristics shown in previous, similar experiments.
The researchers have shown that the in-plane thermal conductivity of the graphene-based film, with 20 micrometer thickness, can reach a thermal conductivity value of 1600 W/mk,
"One example is the integration of graphene-based film into microelectronic devices and systems, such as highly Efficient light Emitting Diodes (LEDS), lasers and radio frequency components for cooling purposes.
Graphene-based film could also pave the way for faster, smaller, more energy efficient, sustainable high power electronics."

In combination with innovative quantitative approaches and numerical simulations, they were also able to define the genome architecture at the nanoscale.

"Up to now, research on oxygen catalysts in thin film form for clean energy applications has been focused on the perovskite-structured oxides
Epitaxial thin films can actually act as more efficient fuel cell catalysts than nanocrystalline powder, but growing Bi2pt2o7 directly as a film requires oxidizing the platinum metal--a challenging step.
The team used pulsed laser deposition to co-deposit epitaxial? -Bi2o3 and disordered platinum. Annealing the film in air forced the platinum to oxidize
and encouraged the formation of epitaxial Bi2pt2o7 crystals about 100 nanometers in length.""Our results provide the only currently-known method to form epitaxial Bi2pt2o7,
Synthesizing the material as a thin film instead of as a bulk powder opens up new possibilities for fuel cell technology."

#High-temperature superconductivity in atomically thin films: A route to developing ultimate superconducting nanodevices A research group at Tohoku University has succeeded in fabricating an atomically thin,

that can be fabricated into a thin film. The research team at Tohoku University turned its attention to iron selenide (Fese),
. While the Tc of bulk Fese is only 8 K(-265°C a signature of higher-Tc superconductivity has been suggested in ultrathin film
The researchers at first fabricated high-quality, atomically thin Fese films Fig. 1, with thickness of between one monolayer (which corresponds to three-atoms thickness) and twenty monolayers (sixty-atoms thickness
by using the molecular-beam-epitaxy (MBE) method*3. Then they carefully investigated the electronic structure of grown films by angle-resolved photoemission spectroscopy (ARPES)* 4 Fig. 2. In the ARPES measurement,
which is direct evidence of the emergence of superconductivity in the films. The researchers found that the Tc estimated from the gap-closing in a monolayer film is surprisingly high (above 60 K),
While multilayer films do not show superconductivity in the as-grown state the researchers have discovered a novel method to deposit alkali atoms onto the films
and thereby control the electron density in the film. By employing this method, the researchers have succeeded in converting non-superconducting multilayer Fese films into high-Tc superconductors with Tc as high as 50 K. The present result gives a great impact to both the basic
and applied researches in superconductors. The researchers have shown clearly how the superconductivity is emerged, enhanced and controlled in atomically thin Fese films.
While the Tc achieved in this study (50-60 K) is still lower than that of the cuprate high-Tc superconductors (highest Tc?
135 K) which caused the"high-Tc fever"in the world 30 years ago, it obviously exceeds the record of other"high-Tc superconductors"such as fullerene (C60) superconductors (Tc 33 K) and Mgb2 (Tc 39k),

#How Streaming Is Changing Music There was a moment in the mid-2000s when it seemed like we might be collecting songs, one-by-one, into eternity.
The era of streaming music is upon us and if you need writing on the wall,
turn to the relentless coverage of Apple's acquisition of Beats Music, a subscription service that is scheduled to be rolled into the itunes platform sometime this year, possibly as soon as next week.
we're going to examine the world of streaming music that is upon us in a series called Streaming At The Tipping Point.
But streaming music has unlocked other new questions for the musician and fan alike: of ownership, of taste and of morality.
What role do listeners play in ensuring the life of music and the livelihood of musicians?
Over digital music's 30-year evolution, from the public introduction of the compact disc in 1981 to the international expansion of Spotify in the last half-decade, the question of whether listeners owned the music they purchased got murkier.
In an earlier era, there was no such question buying a vinyl record meant you could listen to the music until you wore it out,
You weren't buying the music itself when you purchased an album or a song,
In this way, streaming music suggests the passing of two eras: the digital download, but also the concept that fans might possess music itself.
No format lives forever. The LP, the cassette, the CD, the MP3 each one dominated the market for about 15 years before ceding to the next technological advance.
