Nanoparticle meta-grid for enhanced light extraction from light-emitting devices

A tailored layer of plasmonic nanoparticles can be introduced into the epoxy casing of a light-emitting diode (LED) to improve the device's light output, to benefit energy savings and boost the LED lifetime. In a new report on Nature Light: Science & Applications, Debrata Sikdar and a team of scientists in chemistry, electronics and physics at the Imperial College London and the Indian Institute of Technology, showed the benefits of including a two-dimensional (2-D) array of silver nanoparticles known as a 'meta-grid' to the lens shaped epoxy packaging. They tested their theory using computer simulations and demonstrated the ability to improve light extraction from the nanoparticle meta-grid based LED. The alternative approach can be customized to suit a specific color of emission, the authors proposed a few additional schemes to implement the strategy into the existing LED manufacturing technology.

Shock waves might offer the jolt needed to reach Mars

Applying shockwaves can improve conditions for fluid mixing in supersonic combustion engines, paving the way for flights at speeds five times faster than the speed of sound.

A material composed of two one-atom-thick layers of carbon has grabbed the attention of physicists worldwide for its intriguing—and potentially exploitable—conductive properties.

Study reports a transition from spontaneous to stimulated Hawking radiation in a sonic black hole

In 2014 and 2016, Jeff Steinhauer of Technion, Israel, successfully conducted two significant experiments. The first one demonstrated stimulated Hawking radiation in a sonic black hole laser (SBHL). The next one showed spontaneous Hawking radiation from a sonic black hole (SBH). Both experiments were performed in an ultra-cold Bose-Einstein condensate (BEC) of rubidium atoms at nano-Kelvin temperature, an extreme form of quantum fluid almost at absolute zero temperature.

Ultra-fast laser-based writing of data to storage devices

Modern life revolves around data, which means that we need new, fast, and energy-efficient methods to read and write data on our storage devices. Optical-based approaches, which use laser pulses to write data instead of magnets, have received considerable attention over the past decade following the development of all-optical switching (AOS) for magnetic materials. While fast and energy efficient, AOS has issues with precision. Researchers at Eindhoven University of Technology have devised a new method to accurately write data to a cobalt-gadolinium (Co/Gd) layer with a laser pulse using a ferromagnetic material as a reference to help with the writing process. Their research is published in Nature Communications.

Sharing a secret... the quantum way

Researchers at the University of the Witwatersrand in Johannesburg, South Africa, have demonstrated a record setting quantum protocol for sharing a secret amongst many parties. The team created an 11-dimensional quantum state and used it to share a secret amongst 10 parties. By using quantum tricks, the secret can only be unlocked if the parties trust one another. The work sets a new record for the dimension of the state (which impacts on how big the secret can be) and the number of parties with whom it is shared, and is an important step towards distributing information securely across many nodes in a quantum network.

When Dirac meets frustrated magnetism

The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in space, can have special patterns which result in exotic physical properties. Particularly exciting are materials which host multiple types of exotic properties because they give scientists the opportunity to study how those properties interact with and influence each other. The combinations can give rise to unexpected phenomena and fuel years of basic and technological research.

Earth. A new study shows other stars could have as many as seven Earth-like planets in the absence of a gas giant like Jupiter.

New analysis method predicts disruptive solar flares

Solar flares—violent explosions on the surface of the sun—can send blasts of radiation hurtling toward Earth. While the planet's magnetic field protects humans on the surface, powerful solar flares can disable satellites, power grids and radio communications. But scientists aren't sure exactly what triggers solar flares, which makes it difficult to predict when one will occur. One theory suggests these massive explosions can be set off by small disturbances in the sun's magnetic field. Now, researchers have applied that theory to develop a novel method of predicting solar flares before they happen. This method could make the forecasting of solar flares more accurate and reliable than ever before.

NASA's Webb Telescope will study Jupiter, its rings, and two intriguing moons

Jupiter, named for the king of the ancient Roman gods, commands its own mini-version of our solar system of circling satellites; their movements convinced Galileo Galilei that Earth is not the center of the universe in the early 17th century.

Cosmic tango between the very small and the very large

While Einstein's theory of general relativity can explain a large array of fascinating astrophysical and cosmological phenomena, some aspects of the properties of the universe at the largest-scales remain a mystery. A new study using loop quantum cosmology—a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's theory of general relativity—accounts for two major mysteries. While the differences in the theories occur at the tiniest of scales—much smaller than even a proton—they have consequences at the largest of accessible scales in the universe. The study, which appears online July 29 in the journal Physical Review Letters, also provides new predictions about the universe that future satellite missions could test.

Researchers enhance electron spin longevity

The electron is an elementary particle, a building block on which other systems evolve. With specific properties such as spin, or angular momentum, that can be manipulated to carry information, electrons are primed to advance modern information technology. An international collaboration of researchers has now developed a way to extend and stabilize the lifetime of the electron's spin to more effectively carry information.

Long-standing tension in the Standard Model addressed

The best-known particle in the lepton family is the electron, a key building block of matter and central to our understanding of electricity. But the electron is not an only child. It has two heavier siblings, the muon and the tau lepton, and together they are known as the three lepton flavors. According to the Standard Model of particle physics, the only difference between the siblings should be their mass: the muon is about 200 times heavier than the electron, and the tau-lepton is about 17 times heavier than the muon. It is a remarkable feature of the Standard Model that each flavor is equally likely to interact with a W boson, which results from the so-called lepton flavor universality. Lepton flavor universality has been probed in different processes and energy regimes to high precision.

ISOLDE reveals fundamental property of astatine, the rarest element on Earth

A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth. The result, described in a paper just published in Nature Communications, is important for both fundamental and applied research. As well as giving access to hitherto unknown properties of this element and allowing theoretical models to be tested, the finding is of practical interest because astatine is a promising candidate for the creation of chemical compounds for cancer treatment by targeted alpha therapy.
