Researchers achieve unprecedented nanostructuring inside silicon

Posted by in category: electronics

Silicon, the cornerstone of modern electronics, photovoltaics, and photonics, has traditionally been limited to surface-level nanofabrication due to the challenges posed by existing lithographic techniques. Available methods either fail to penetrate the wafer surface without causing alterations or are limited by the micron-scale resolution of laser lithography within Si.

Belle II experiment reports the first direct measurement of tau-to-light-lepton ratio

Posted by in categories: electronics, particle physics

The Belle II experiment is a large research effort aimed at precisely measuring weak-interaction parameters, studying exotic hadrons (i.e., a class of subatomic particles) and searching for new physical phenomena. This effort primarily relies on the analysis of data collected by the Belle II detector (i.e., a general purpose spectrometer) and delivered by the SuperKEKB, a particle collider, both located at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan.

Quantum sensors: How does the flow profile affect flow measurements?

Posted by in categories: electronics, quantum physics

Researchers at Fraunhofer IPM have developed a contactless flow measurement method based on magnetic fields. For the first time, they have been able to show the quantitative impact of the flow profile on the magnetic signal. This opens up new possibilities for improving the measurement method.

The results were recently published in the Journal of Applied Physics.

There are many manufacturing processes across various industries where flowing liquids play a key role. Controlling or automating such processes requires reliable data on the rate of the liquids. The -based flow measurement technique developed at Fraunhofer IPM provides accurate flow data without any contact with the liquid.

Shining a light on oil fields to make them more sustainable

Posted by in categories: electronics, sustainability

One of the most common problems is spills of the salty brine that’s a toxic byproduct of pumping oil. Another is over-or under-pumping that can lead to machine failure and methane leaks. (The oil and gas industry is the largest industrial emitter of methane in the U.S.) Then there are extreme weather events, which range from winter frosts to blazing heat, that can put equipment out of commission for months. One of the wildest problems Sebastien Mannai SM ’14, PhD ’18 has encountered are hogs that pop open oil tanks with their snouts to enjoy on-demand oil baths.

Mannai helps oil field owners detect and respond to these problems while optimizing the operation of their machinery to prevent the issues from occurring in the first place. He is the founder and CEO of Amplified Industries, a company selling oil field monitoring and control tools that help make the industry more efficient and sustainable.

Amplified Industries’ sensors and analytics give oil well operators real-time alerts when things go wrong, allowing them to respond to issues before they become disasters.

‘Acceleration beats’ shine bright light on a novel universal modulation regime in a semiconductor-based laser

Posted by in categories: electronics, quantum physics

Researchers at the Paul-Drude-Institute for Solid State Electronics (PDI) have observed a novel modulation regime characterized by the emergence of previously unseen “acceleration beats” in a modulated semiconductor-based laser.

As they detail in a paper published today in Nature Communications, the key—and somewhat counterintuitive—feature of this novel regime is the ability to coherently manipulate using modulation periods longer than the coherence time, provided that the modulation amplitude is large enough.

Harmonic modulation of light sources, such as lasers, is the cornerstone of many modern and emergent telecommunications technologies. In this regard, two regimes of modulation are well-known: the adiabatic regime and the non-adiabatic regime.

Trillionth of a Second Shutter Speed Camera Captures Chaos in Action

Posted by in categories: electronics, materials

To take a picture, the best digital cameras on the market open their shutter for around around one four-thousandths of a second.

To snapshot atomic activity, you’d need a shutter that clicks a lot faster.

With that in mind, scientists have unveiled a way of achieving a shutter speed that’s a mere trillionth of a second, or 250 million times faster than those digital cameras. That makes it capable of capturing something very important in materials science: dynamic disorder.
