The darkest material on Earth has become even darker

Posted by in categories: electronics, materials, transportation

New material improving stealth mode vehicles and planes.


When Surrey NanoSystems introduced the original Vantablack, the company said the carbon nanotube material is capable of absorbing 99.96 percent of light that touches it. It’s so dark, it can fool your eyes into seeing a smooth surface even when the nanotubes were actually grown on crumpled foil (seriously — watch the video below the fold). Well, the new version of Vantablack is darker than that. In fact, Surrey can’t even give us the percentage of light that gets absorbed, because its spectrometers can’t measure it.

In this video below (and the GIF above), you can see the material engulf the laser pointer in darkness when it moves across:

Physicists promise a copper revolution in nanophotonics

Posted by in categories: computing, electronics, nanotechnology, physics

Researchers from the Moscow Institute of Physics and Technology (MIPT) have for the first time experimentally demonstrated that copper nanophotonic components can operate successfully in photonic devices – it was previously believed that only gold and silver components could do so. Copper components are not only just as good as components based on noble metals; they can also be easily implemented in integrated circuits using industry-standard fabrication processes. “This is a kind of revolution – using copper will solve one of the main problems in nanophotonics,” say the authors of the paper. The results have been published in the scientific journal Nano Letters.

The discovery, which is revolutionary for photonics and the computers of the future, was made by researchers from the Laboratory of Nanooptics and Plasmonics at MIPT’s Centre of Nanoscale Optoelectronics. They have succeeded, for the first time, in producing copper nanophotonic components, whose characteristics are just as good as those of gold components. It is interesting to note that the scientists fabricated the copper components using the process compatible with the industry-standard manufacturing technologies that are used today to produce modern . This means that in the very near future copper nanophotonic components will form a basis for the development of energy-efficient light sources, ultra-sensitive sensors, as well as high-performance optoelectronic processors with several thousand cores.

The discovery was made under what is known as nanophotonics – a branch of research which aims, among other things, to replace existing components in data processing devices with more modern components by using photons instead of electrons. However, while transistors can be scaled down in size to a few nanometres, the diffraction of light limits the minimum dimensions of photonic components to the size of about the light wavelength (~1 micrometre). Despite the fundamental nature of this so-called , one can overcome it by using metal-dielectric structures to create truly nanoscale photonic components. Firstly, most metals show a negative permittivity at optical frequencies, and light cannot propagate through them, penetrating to a depth of only 25 nanometres. Secondly, light may be converted into surface plasmon polaritons, surface waves propagating along the surface of a metal. This makes it possible to switch from conventional 3D photonics to 2D surface plasmon photonics, which is known as plasmonics. This offers the possibility of controlling light at a scale of around 100 nanometres, i.e., far beyond the diffraction limit.

Are Quantum Dots the Silicon Wafers of the Future?

Posted by in categories: electronics, quantum physics

I cannot wait until Q-Dot technology is commercially available to industries. When we start releasing Q-Dots to the commercial sector we’re going to see some real magic happen and possibly even able to improve many things that are refined, or created today. https://lnkd.in/bF4xm73


Silicon wafers have long been the go-to for all things electronic. First appearing in the ‘50s, they quickly made it as THE connectors, basically singlehandedly kickstarting the silicon revolution. A team of researchers from the Cornell University have discovered something they consider to be the next big step in quantum electronics. They are quite certain of the answer to the question “Are Quantum Dots the Silicon Wafers of the Future?”.

ATR 72 prototype tests all-electrical energy management system

Posted by in categories: electronics, energy, materials, transportation

European turboprop aircraft manufacturer ATR said a prototype ATR 72 conducted a demonstration flight to test an all-electrical energy management system that aims to optimize electrical power distribution.

The flight is the second the ATR 72 demonstration aircraft has flown as part of the European Union’s “Clean Sky Joint Undertaking” program. The first test flight by the ATR 72 prototype, conducted in July 2015, trialed “new and more effective composite insulation materials and new vibro-acoustic sensors integrated into a large panel of the ATR aircraft fuselage,” ATR said in a statement.

The manufacturer said the two demonstration flights “also tested new generation optical fibers for improved identification of micro-cracks and easier maintenance.”

Artificial control of exciplexes opens possibilities for new electronics

Posted by in categories: computing, electronics, materials, solar power, sustainability

Demonstrating a strategy that could form the basis for a new class of electronic devices with uniquely tunable properties, researchers at Kyushu University were able to widely vary the emission color and efficiency of organic light-emitting diodes based on exciplexes simply by changing the distance between key molecules in the devices by a few nanometers.

This new way to control electrical properties by slightly changing the device thickness instead of the materials could lead to new kinds of organic electronic devices with switching behavior or that reacts to external factors.

Organic such as OLEDs and organic solar cells use thin films of for the electrically active materials, making flexible and low-cost devices possible.

Quantum dot solids: This generation’s silicon wafer?

Posted by in categories: electronics, engineering, quantum physics, solar power, sustainability

Just as the single-crystal silicon wafer forever changed the nature of electronics 60 years ago, a group of Cornell researchers is hoping its work with quantum dot solids – crystals made out of crystals – can help usher in a new era in electronics.

The multidisciplinary team, led by Tobias Hanrath, associate professor in the Robert Frederick Smith School of Chemical and Biomolecular Engineering, and graduate student Kevin Whitham, has fashioned two-dimensional superstructures out of single-crystal building blocks. Through directed assembly and attachment processes, the lead selenide quantum dots are synthesized into larger crystals, then fused together to form atomically coherent square superlattices.
