Ultrafast UV-C laser pulses generated and detected using 2D materials

Scientists have developed a new platform for the generation and detection of ultrashort UV-C laser pulses on femtosecond timescales. This breakthrough could unlock new opportunities for transforming optical wireless communication systems, material processing applications and medical imaging.

Scientists from the University of Nottingham’s School of Physics and Astronomy and Imperial College London developed the new platform. The source produces pulses of femtosecond duration, less than 1 trillionth of a second. These pulses are detected at room temperature by sensors based on ultrathin (two-dimensional, 2D) materials. The paper is published in the journal Light: Science & Applications.

Professor Amalia Patané, from the School of Physics and Astronomy at the University of Nottingham, led the development of the sensors. “This work combines for the first time the generation of femtosecond UV-C laser pulses with their fast detection by a new class of 2D semiconductors. These can operate over a wide range of pulse energies and repetition rates, as required for many applications,” says Patané

Physicists Rewrite Thermodynamics for the Quantum Age

Researchers have devised a new way to define thermodynamic concepts in microscopic quantum systems, where conventional distinctions between heat and work begin to blur. Researchers at the University of Basel have introduced a new way to apply thermodynamic principles to very small quantum systems

Astronomers Discover a Star That Breaks the Rules Orbiting a Silent Black Hole

Astronomers have uncovered clues to a red giant’s chaotic past by detecting subtle stellar vibrations that hint at a long-ago collision and an unexpectedly rapid spin. Astronomers at the University of Hawaiʻi Institute for Astronomy (IfA) have pieced together the turbulent history of a distant re

Beyond Einstein: Could Our Universe Have Seven Hidden Dimensions?

The geometry of space, the setting in which physical laws operate, may hold clues to some of the biggest unanswered questions in fundamental physics. The underlying structure of spacetime itself could be the foundation for every interaction observed in nature. A study published in Nuclear Physics

Dark Matter May Have Finally Been Detected in Our Galaxy’s Glow

A strange, never-before-seen glow in the halo of our galaxy may be the strongest dark-matter breadcrumb yet.

A new analysis of 15 years’ worth of data from the Fermi Gamma-Ray Space Telescope reveals a glow of unusually high-energy gamma rays that cannot easily be attributed to any known source.

According to astronomer Tomonori Totani of the University of Tokyo in Japan, it may be the radiation produced when hypothetical dark matter particles collide and wipe out one another.

Your Brain Goes Through 5 Distinct Epochs, Massive Study Finds

The human brain is not a hard-wired machine but a malleable organ that is regularly re-shaping itself.

Neuroscientists at the University of Cambridge in the UK and the University of Pittsburgh in the US have now identified four major turning points in brain wiring between birth and death.

Like chapters of our lives, each of these neurological ‘epochs’ marks a new era of development or decline.

Scientists Cracked Open a Lunar Rock And Found a Huge Surprise

A tiny sample of the Moon locked away for more than 50 years turns out to have been hiding an astronomical secret.

In specks of troilite dust collected by Apollo 17 in 1972, scientists have found material that may be as old – or even older – than the Moon itself, a 4.5-billion-year-old relic of the early Solar System.

“My first thought was, ‘Holy shmolies, that can’t be right,’” says planetary scientist James Dottin of Brown University in the US.

When Your $2M Security Detection Fails: Can your SOC Save You?

Why did all eight detection tools identically fail where the SOC succeeded?

What all these organizations have in common is a balanced investment across the alert lifecycle, which doesn’t neglect their SOC.

This article examines how investing in the SOC is indispensable for organizations that have already allocated significant resources to detection tools. Additionally, a balanced SOC investment is crucial for maximizing the value of their existing detection investments.
