Harnessing the powers of light to operate computers

It is said that light is the source of life, and in the near future, it will possibly form the basis of our everyday personal computing needs too. Recently, researchers from the University of Tsukuba have harnessed specific energies of light from a "packet" of light by creating a nanocavity, which may help in the development of future all-optical computers.

Skyrmions on the rise: New 2D material advances low-power computing

Two-dimensional magnetic materials have been hailed as building blocks for the next generation of small, fast electronic devices. These materials, made of layers of crystalline sheets just a few atoms thick, gain their unique magnetic properties from the intrinsic compass-needle-like spins of their electrons. The sheets' atomic-scale thinness means that these spins can be manipulated on the finest scales using external electric fields, potentially leading to novel low-energy data storage and information processing systems. But knowing exactly how to design 2D materials with specific magnetic properties that can be precisely manipulated remains a barrier to their application.

How quantum weirdness is improving electron microscopes

Quantum weirdness is opening new doors for electron microscopes, powerful tools used for high-resolution imaging.

New theory explains mystery behind fast magnetic reconnection

When magnetic field lines of opposite directions merge, they create explosions that can release massive amounts of energy. On the sun, the merging of opposing field lines causes solar flares and coronal mass ejections, giant bursts of energy that can travel to Earth within a day.

Researchers add antireflection coatings to complex 3D printed micro-optical systems

Researchers have developed a new way to apply antireflective (AR) coatings to 3D printed multi-lens systems as small as 600 microns in diameter. Because these coatings help minimize light losses due to reflection, they are critical for making high-quality 3D printed systems consisting of multiple microlenses.

Researchers design simpler magnets for twisty facilities that could lead to steady-state fusion operation

Harnessing the power that makes the sun and stars shine could be made easier by powerful magnets with straighter shapes than have been made before. Researchers linked to the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a way to create such magnets for fusion facilities known as stellarators.

'Lensless' imaging through advanced machine learning for next generation image sensing solutions

A camera usually requires a lens system to capture a focused image, and the lensed camera has been the dominant imaging solution for centuries. A lensed camera requires a complex lens system to achieve high-quality, bright, and aberration-free imaging. Recent decades have seen a surge in the demand for smaller, lighter, and cheaper cameras. There is a clear need for next-generation cameras with high functionality, compact enough to be installed anywhere. However, the miniaturization of the lensed camera is restricted by the lens system and the focusing distance required by refractive lenses.

Laser-based ultrasound detects defect-producing features in metal 3D printing

Lawrence Livermore National Laboratory (LLNL) researchers have developed a new all-optical ultrasound technique capable of performing on-demand characterization of melt tracks and detecting formation of defects in a popular metal 3D printing process.

Time‑correlated single‑photon counting technique to visualize weak pulse electroluminescence

Time‑correlated single‑photon counting (TCSPC) technique is a powerful way to measure the weak light signals. The basic principle behind TCSPC is the photoelectric effect in which an electrical charge is released by absorbing a photon. Compared to the traditional strategy of detecting analog photogenerated voltage, the TCSPC technique counts the single electron pulse created by single photons, which means its sensitivity can be up to single-photon level as its name implies. In fact, the TCSPC technique has been successfully employed to detect the transient/burst photoluminescence (PL) in many research fields, and the transient spectrometer is common equipment in many labs.

New method can predict summer rainfall in the Southwest months in advance

As reservoir levels dwindle in the arid southwestern United States, scientists have developed a method to estimate summer rainfall in the region months in advance. Such seasonal predictions can help state and local officials make key reservoir storage and water allocation decisions earlier in the season and support more efficient water management.

Model pinpoints glaciers at risk of collapse due to climate change

As climate change warms the planet, glaciers are melting faster, and scientists fear that many will collapse by the end of the century, drastically raising sea level and inundating coastal cities and island nations.

Research team finds that some magmas originate from mantle portions containing remnants of Earth's earliest crust

In an international collaboration, Earth scientists at the University of Cologne and Freie Universität Berlin have discovered that some magmas on Earth, which made their way through the deep terrestrial mantle and erupted at Earth's surface, originate from mantle portions that contain remnants of Earth's earliest crust. This ancient material must have been buried in a "graveyard" of old and cold crust more than 4 billion years ago and survived since then, maybe since the giant impact event that formed the moon.

Diminishing Arctic sea ice has lasting impacts on global climate

As the impacts of climate change are felt around the world, no area is experiencing more drastic changes than the northern polar region. Studies have shown the Arctic is warming at two to three times as fast as the rest of the planet, resulting in a rapid loss of its sea ice volume.

How are the physical characteristics of the coal-fluid system reflected in ultrasound?

Around the beginning of the 21st century, the world economy entered a new development cycle, and the demand for oil and natural gas resources around the world has skyrocketed. In the face of this huge energy demand, people are beginning to pay more attention to unconventional oil and natural gas resources. Coalbed methane (CBM) is a gas resource associated and symbiotic with coal. CBM is mainly hydrocarbon gas adsorbed on the pore surface of coal matrix and partially freed in pores or dissolved in water. It is, as an associated mineral resource of coal, a clean, high-quality energy and chemical raw material. It is well-known that the burial depth of CBM reservoirs ranges from hundreds of meters to several thousand meters, and its gas-liquid-solid interaction mechanism is complex. So, it is often necessary to obtain the fluid-coal information by means of, for example, acoustic logging. At present, many scholars have carried out the acoustic research on the fluid-coal system. However, there are relatively few studies on the acoustic characteristics of the gas-liquid-solid linkage effect, especially the fluid saturation effect under different coal rank conditions.
